Booster's Landspeed racer

[TurboKat]

The worlds fastest SRAD ? (not a bad title for a movie [:I])
Are you allowed to use different profile windscreens Greg? From the pic it looks like maybe the aero's might benefit from a taller "Touring" type screen or maybe a GP style "Double Bubble"
I'm sure you've considered this - being a World Landspeed Record holder & all - so feel free to tell me to fuck off & stick to Roadracing.
Oh yeah, what tyre pressures do you run for this stuff?
Keep up the good work mate.

[Booster]

Thanks for the resize, bit hard to see pixal by pixal :D

Lots of real name guys out here but i'm just a small fish in a big pond, one that made the biggest impression on me was Roger Goldammer, if the name doesn't ring any bells look him up, one of the simplest most impressive bikes i have seen [8D]

That run hurt my neck.. kept thinking "hurry up.. hurry up can't do this much longer,so i brought a double bubble , see if that helps , Tires at 45psi, holding real well, new Dunlop tourer.

[Z Power]

Good stuff booster, your a fucking legend

[Iceman]

Well done Greg. Sounds like your having ball. How long before you're back in oz?

[Booster]

26th landing in melb, leaving here on the 24th... go figure it only took 45 mins to get here...
1 run today foulded plugs. popping and farting for a 164
6th in line for a run tomorrow..

[gibbo]

Good luck Greg, woulda thought farting would produce extra boost! Go fast Tomorrow!!!!!

Bit of an update to the saltlake racing too
The blue bike is now NAKED and red and has run over 200mph like this, i have done 199 on it , Damn windy :D
The bike i used to build the kit on in 08 now travels to the US to give us a 2 bike team, My mate Jim in Cali houses the naked bike , now co owns it and races it at other meets during the year

The Aussie 750 has busa landspeed fairings, in 09 it ran a gt2871 , undertank air/air intercooler, sealed from the engine heat and fed air from the centre of the nose fairing , running on methanol, best one way pass was 220 mph but it hurt the engine in that run mid track, and the 220 was rolling through the top of the timed mile with 1 dead and another injured cyl

[latheboy]

Awesome Greg, why has the fairing been taken off?

[Booster]

To run in other classes, and its a bit of a challenge trying to get 200mph out of a 750 with no aero help ,
Jim was keen to try it so we thought why not

[Booster]

Currently working on an icebox and water/air intercooler for the aussie bike
12 litres capacity with internal pump should last the 3 mins it takes to get from standing start one end and stopped 5 miles later

Nice work with the chilli box mate,go camp Kiwi.

[Booster]

LOL.. that was the Kiwi end of our pit, Sponser was Kiwi , but the Aussie flag was flying on the next post and the stars & stripes on the next , for all the members of our group , next meet had Steve and his crew , so the pommie flag was flying too

[rock hard]

Absolutly fuckin awesome greg,man you inspire me to put the Bullfrog bike on the salt..Jeremy and his brother Lee loaded his bike up and drove across from perth
a couple of years ago but when they got to lake gardiner it was wet.
they drove back without getting a run.and typical of Bullfrog no complaining
he was chuffed to be able to do the trip with Lee and always intended to return
to the salt.might have to find a way to tick that box for him..
Rocket is keen to run the Turbo if i can get the dollars
we are on our way..

[rock hard]

Booster, just curious about the detonation and erroded valve.
was it boost/ign fuel air?and what did the other cylinders look like.and thanks for posting these threads are awesome for what you have achieved..nice work

[Hagarr]

Mozz you are gonna do this I can sense it.

As they say in the classics "Just Do It"

Thats Bonneville USA Mozz,last time i heard Lake Gairdner was damp again,but it dries up quick.I think i just worked out why my turbo is so rusty.

[rock hard]

Thanks Davo, yes haggar but we need a truck.Trouble is Toni doesnt understand my obsession,come to think of it neither do i .ButWHO CARES.
i know that the older i get the more i Feel ALIVE
when im on the bike givin it shit..obsession-- addiction
its fuckin AWESOME.

[Booster]

We ran at Gairdiner in March, was wet for the first few days but dried out as the week went on, best day was the last when Brett DeStoop ran his 1000cc waterbottle to 232mph, bloody spectacular.

Yep Moz, that was an a/f problem , bloody methanol, log shows good a/f but obviously all parts of all cyls were not the same .
going back to c 16 style race fuel, and thats why the better intercooler on this bike , similar to the 08 bike that has been so reliable .
Just remember the salt is very corrosive, and when your trying to wash it off you can cause it to wick up inside the wiring,
coat everything in lanoline spray (brigs and stratton have a good pressure pack ), silicone grease all electrical plugs and hot glure gun the backs of connectors , its messy but can save a lot of drama later.. cad plating can discolour in a day and pitted fork legs in a week , steering bearings shock links and wheel bearings will show signs of siezing 6 months later and keys will not turn about mid winter after a couple of foggy or damp days ... nasty shit salt ...
major cleanup needed after

[rock hard]

Thanks Greg, thats good info,was wondering about the ways to keep all that alkaline at bay..

Bit more of the latest work

looking good mate well done

[Booster]

Thanks Deano, getting there slowly, missed getting anything done today, trying to get the VIV for the bus ... what a pain in the ass the whole VIV thing is..
Back out to the shed for a few hours this evening then on the dyno tomorrow ..

[Surt]

awesome story Booster! didnt know i was talking to a worlds celebrity [:p] wtf is viv i luv vidsvidsvidsvids!!! [8D]

[Booster]

VIV is a local vehicle check to put an accident damaged bike back on the road, you need receipts of everything that was replaced , including VIN numbers of the doner bikes if the parts were secondhand and pics of the repairs as there getting done and abn numbers of the suppliers of new parts

Vids this year for sure , brought one of the 3.99 ebay cameras
actually at that price i'm thinking of getting several, could have all the angles Rossi or Stoner does :)
Be good to see the wheelspin or playback the gauges, one of my favorite youtube vids is Scott Horner on his bronze turbo busa at Bonneville with a rear facing camera

[Booster]

Well the bike is in its box and heading for the Wild West , not that California is that wild anymore..
Will see it again in late Aug.
Had a hickup tuning, the aem lost injector reference above 10k rpm, had several of these units and not seen that before, funny to see the boost rising but the rpm indicator falling on full throttle
so a last min change to a microtech secondary system, full day modifying another plenum to fit the 750 and wiring it in then tuning, still breaking down some and not revving beyond 11500 but generally its pulling to 30 psi and can make repeated runs hot without probs so even if it will not sound great it should still do ok, and i may be able to track down the probs in Cali before we go racing . i have paid out too much that it would not cost less to not take the bike now whatever state it was in.

Hey Booster, thats amazing i hope it works a treat when you get it out on the salt.there is always a point in any project that all the work is all done then its fingers crossed and GO..just a side note in the vane of burt munro are you going to hop on a crappy ship and work as the cook! if so you better get working on your welsh/kiwi accent...seriously though..GOOD LUCK MATE...morry

[Booster]

Thanks Morry
About on Berts budget this time, But we have some help, Local Suzi dealer helps on parts prices , Triumph guy gives me the bike crate and straps , & co rider Kim has raised some money towards shipping in her local community, most welcome and unexpected was from the Yackandanda historical society who figure there helping a local gal make history, i hope we can get Kim her red hat with lots of pics and detail and realy give them value for money

I'll do the washing up in the plane, only a couple of meals to worry about :)

[RevHead]

im sure you,d be much better fitting a busa rear end to the 750 as there wind tunnel tested that fibreglass rear end looks like it,l cause drag and lots of drama ,a rear end that big will cause it to weave,

[Booster]

The rear end in page 1 or 2 was shithouse, weave at 175mph , put the std one back on and rock solid
the trouble with the "aerodynamic" one pictured is its too short and the sides taper in too quick.
the air needs to reattach its self to the fairing after the turbulance of the rider , then you can guide it back and leave a very small wake , a good example of bad air is this vid of me in 09 http://www.youtube.com/watch?v=RyOmmOMFnbc
see the dotted salt in my wake, very disturbed air .. i'm pulling a large vacuum behind me costing as much speed as parting the air in the first place , needs to be like a hi diver entering the water with no splash.
once the air is reattached you can curve the tail in and the air will bend some .
another tail i keep going to try but never get time to finish it was made by another ASF member, Bones
i'll post some pics .

[Booster]

This was dummied up on my busa and looking to improve the fairing , the printers aluminium is cut at the approximate shape i was after
this is still too low at the rear of the rider , it needs to be higher at first then curve more, and the sides are too flat, it should be parrallel for a bit then curve in .
Gave this and another fairing to another of the guys in our container that has put in extensive work in a wind tunnel , his ideas are very close to mine and will make up a plug using parts of each then we each will have a good rearend

Fastest ever pass on a sit on bike by Joe Amo on an oldschool zx10 at 272mph shows just how good things can get if you get the aero right

[RevHead]

yeah im pretty sure if the arse end finished into a point you,d defeet drag

[Booster]

Unfortunately regs don't let it get that long, from 200-400mm depending on what class and which event (also some require a 180 deg view of the wheel) , so the next best is a squared off end , the air continues on as if the tail were complete and leaves a much smaller footprint than the rear view may suggest

[Booster]

Back home again
Bikes worked a treat , only had a few engine probs and mostly no handling issues
Fastest pass by Jim the US side of our team was 225mph,
By Kim Aussies fastest motorcycling lady was a 220mph mile average with a 227mph exit speed, (still accelerating , too bad there was no timer in the next mile[:p])
And 229mph by myself, which was the fastest time of the meet at the 2010 Bubs event , turbo busa's were having terrible handling probs
Aussie bike ended up as seen in the following pic, after just running 2 228 mph passes for a 228mph record at the last event we entered, the World Of Speed put on by the Utah Salt Flats Racing Association

A few vids are appearing, this is of day 3 at the Bubs meet

http://www.youtube.com/watch?v=d-JusoG9aWY&feature=related

I'm at 5.30 and 8.23 or so
Thanks again guys, hope you don't get too sick of me pushing this a bit more in the next 12 months, hoping to get better support for next year and with better bodywork look towards the hi 240's to 250mph , so as much as i am uncomfortable about putting ourselves out there and getting press etc, were going to try harder and see if we can get some backing and do it better
Plans for next year are all aero mods
This bodywork made by Ralph Hudson in CA went 211mph on a mostly std gsxr750, i figure thats 30 mph advantage from std
http://img.photobucket.com/albums/v378/maj750/3DAY_RECORDS_0081.jpg
and Kim was presented with a womens encouragement award from SheEmoto in California,Promoting women in landspeed racing ... some of that money went straight to Ralph for a new back half on the bike .
we can test the 2 tails in March back to back , aero will make a bigger difference here with our lakes low altitude

what tyre d'u use on the salt Greg? any 'upgrade' to be done to it like shaving or smth?... already asked yankers but theyve never bothered to reply

[Booster]

Tire regs are going through some revision , we had to use "race rubber" this year at the SCTA events , previously z rated touring road tires were the preferred option, hopefully the z rated tires will be allowed back in .Also i have heard of a specific motorcycle landspeed tire in the works, that would solve all these issues if that is fact .
Shaving helps and was recommended for the touring tires for the very high speeds like 250+
I have a tire that has done 260mph from Rich Assens bike last year and it looks like it just come off the shaving machine.
We will be using it on the Aussie Busa in March ,

[Surt]

i'd luv to see what it looks like to have a slightest idea what the shaving is all about? as well as the shaving machine - never heard of
wats the essence of shavins - removing grooves to make it a slick like or to make it lighter or some special profile or wat?

[Booster]

Tire is still in the container on its way home but its basicly put in a machine that spins the wheel/tire combo and a very sharp mounted blade is used to remove most of the rubber and shape the tire , think tire lathe...

[Booster]

Well its nearly March and racing is getting close
This years mods are mostly looking for better aerodynamics , and improve the electronics
Going to fit a 07 gix ecu and loom as they are reflashable, this will let me tune the ecu directly, and let me use various "added" features like logging,autotune,traction control,rev limit control,Boost fueling, gear based boost control.. Can't wait to try it all out
Fairing tail arrived, just sat in the foreground to get a feel of how it will look and fit
http://img.photobucket.com/albums/v378/maj750/1298082353294.jpg
Not much change needed to fit , but have to extend the filler on the ice tank so i can access it via a hatch in the tail

[BANDITROD]

Looking good greg but your gunna need a longer trailer

[Booster]

That seems so obvious now you have pointed it out but i spent all my time looking at the fit on the bike the trailer may as well not be there [:I] ... they travel in the back of the ute but its 7 ft like the trailer , may have to loose the tailgate and use a net .

[80s freak]

Looks the biz Greg. Is it the same unit as Chris Brysons?

[latheboy]

Wow that's a whole lot of tail.... You need to find someone with a wind tunnel and mate friends...

[Booster]

Not sure what Chris has this year, lots of guys buy the one like i had earlier, (pg2-3 i think )
The guy that made this has only sold a few so far, , i am also making one for my busa, trying the tail we used in the last week in the US , but longer, and the lower section filled in
http://img.photobucket.com/albums/v378/maj750/1298079560680.jpg
And its already gone through several changes since this pic... 18 days to go and counting ...

[Dynomutt]

Interesting thread this one, cracking results so far, what pistons are you using? They look like stock items.I know cost is an issue with any of these things but I'd be inclined to switch from stock exhaust valves to some aftermarket items like Kibblewhite or Ferrea, they'll be a lot more durable. You can slot a 750K5 motor into the SRAD chassis, which would be a better starting point, newer more powerful lump to start with. I'd also look at using a larger turbo, to help reduce the inlet temps. Have a look on 750Turbo website, Lorcan Parnell has been doing some nice things with an old Kawasaki 750 turbo, albeit bored to 810cc.

[EXBEN]

quote:You can slot a 750K5 motor into the SRAD chassis, which would be a better starting point, newer more powerful lump to start with.
But then you'd have to change the whole motor when you blow it up, the SRAD has seperate barrels,& they are cheaper on parts, there's a reason for everything....

[EXBEN]

Tail looks good BTW Booster, There's gotta be a few MPH in that.

[Booster]

Yep stock pistons, not had any probs with pistons yet, apart from one that was hurt after a wastegate hose burnt through , cut through the piston top and out through the skirt and nearly all the way through the cyl wall , has the look that it all happened during one stroke of the piston as there is bugger all smearing or other damage , another plazma event ???
I don't like stainless valves, stock are fine , when they have been hurt there was a fault, prefer to fix the cause .

the Srad motor is much more durable than the later ones , heavier rods,pins, crank,gearbox, and as Ben said, the cyls lift off making it easier to service in the field , easier to decompress,

Turbo is getting pretty big now, 2871 next will be a 3071 to try and improve exhaust flow , but i'm not in any hurry to change the compressor size, maybe a new gtx wheel when there available will improve the inlet side and get better effiancy at high boost.

I have been a regular reader and occasionaly comment on Lorcans site , between him, Gary Evans and Rick Yacoucci i learn a hell of a lot when i first started playing with turbo's on bikes

Ben i hope there is a lot of mph as its taking lots of time that i realy don't have , just hope i don't turn a straight arrow into a swimming salmon

[Dynomutt]

I would have thought that making some new headers would improve the flow no end. Ideally try and get them all equal lengths, and port the part where all 4 join together. Have a look at 200mph.org there's a lot of guys going very quickly on there, and you'll find some really useful info from some kindred spirits. You'll see Lorcan is also on there, as well as some very quick Busa SSB guys. There's also a lot of guys doing the flyers as well so it's not all 1/4 mile stuff.

[Tony Nitrous]

Sorry if I missed it in the thread Greg,
but is your 220mph run still a record ?
and does the tail change your class ?
Streamlined and not production shape ?

Good luck and hope all go's to plan.

Tony.J.

[Iceman]

Looking good Greg. Just remember if it does start to wag it's tail, all's you have to do is stick you head up. I've seen it on TV it must be true!

[Booster]

Yeah those headers have been replaced, the mild steel was showing the salt and heat damage
Probably gets a bit mixed up in these long threads, there are 2 750's now one always in the US and one that travels, first build pics went on the US bike , later built stuff went on the Aussie bike that had a lot of upgrades, stuff that worked was then fitted to the US bike too, like the headers
V3.0
http://img.photobucket.com/albums/v378/maj750/1298928446929.jpg
Met one of the 200mph guys at Bonneville last year Barry , he has a BigCC built Busa, He ended up pitting next to us , hope to catch up with him again next year :)

Tony i still have records in MPS class but have moved to APS class with these changes , M cannot have the rear tailpiece beyond the tire, A gives a lot of extra length, Aussie A is 400mm US A is 250mm FIM is half the tire diameter , so the angle grinder will come out after the Aussie meet

Clint if it wags its tail too much i'm rolling off the throttle , there is always some movement but no sense pushing beyond safe, not like the run is the one and only chance you get in the week, if there is an issue we try and address it then run again..i am bringing a more standard tail too..

[Dynomutt]

Have a look at the NLR headers, they are a work of art, and flow beautifully. Personally I'd bring the outer 2 cylinders in at the back and the centre two out over them and into the front, and siamese all 4 in together. A lot dpends on what space you have available behind the wheel. There has been some experimentation recently with side mounting the turbo with the intake facing forwards, but you may not be able to run that due to the salt. I'm currently building a 750 long stroke oil cooled turbo, although I have bored mine to 1003cc, using a relinered short stroke block and matching gasflowed DOT head and 09 busa pistons running on a knife edged balanced and polished crank with Carrillo H beam rods, with a T25 blowing through 34mm CV carbs. I'm aiming for around 200 to 220bhp, in a bike which weighs in at about 180kgs wet, with upto a 68 inch wheelbase.

[Booster]

Sebs look too good to put on a bike , not much room to get artistic, and have the turbo gravity drain , as it is it smokes a little some times if idling for a while but has no ill effects , currently i think i have enough hp to go much faster if i can get the bodywork right figure i'm near 350hp at the moment, have to put the hp part of my dyno into operation one day when i'm tuning, uses the same serial port as my enginemanagement and have to restart the laptop to let a different device use that port , so most times i can't be bothered its only a number when i'm looking for specific a/f ratios and not peak hp
I wouldn't sidemount , don't think there is any real advantage just different and in your face , and definitely not aerodynamic like i need

Nice project :) have you considered a bigger turbo , looking at your combination a t25 seems fairly conservative , will boost early but i think exhaust flow will be restricted in the top of your rpm range

[Dynomutt]

There's a reason for using the T25, the bike is mainly going to live on the road. Wheer I live is all small twisty A roads, and even twistier B roads. I have a T28 sitting waiting for a rebuild if it needs to go larger, but round here it will be hard to get maximum speed out of it, the arm will have the option of going to 68 inch wheelbase if I want to take it out on the strip as I have two NSA meetings fairly local to me.
My old 750K5 fighter had 134bhp N/A at the wheel with another 30 dry shot, and weighed around 150kgs, and was utterly psychopathic on the roads round here, which is why I sold it before I got seriously smashed up again ( last big off broke 18 bones).
My ZRX650R Kawasaki is ideal on the roads around here, but I want something bonkers to play on again. My Zed1000J caff racer is good for the twisties, but gets a bit boring.
What dyno are you running? I currently have a Dynojet200 with the WinPEP7 software. I'm looking to upgrade to a 250 equivalent with the addition of the eddy brake, but I'm limited for weight and space, my dyno is in a vehicle, which enables me to attend various shows etc, and gives me more space in the workshop. It's possible to use an eddy brake from a bus or lorry, Telma retarders come up for sale regularly at sensible prices. Mercedes City bus type things have a good eddy brake which can be fitted to a Dynojet drum fairly easily, and is quite a bit smaller and lighter than the DJ one, I've looked at using one of those mounted behind the drum driven by a large toothed belt like a Harley primary belt driven by a small pulley in place of the hydraulic disc brake assembly. They run from a 24V system on the Bus, which is easy to use as my truck is 24V. The Dynojet eddy brake is slightly too wide to fit and gets me too close to the weight limit on my ex library truck.

[Booster]

Its a home build http://wotid.com/dyno/ , have thought about fitting a retarder, there less common out here , i think its MAN or Scania trucks the most common, the Merc city sounds interesting , have to check UK ebay more often , then its a matter of changing the currently fairly simple software ... Wayne at Tuneboy has mentioned helping with this previously , should give him a call again :)
I found i preferred a larger turbo on my streetbike, (gen 2 busa with gt3071) had used a gt28r and 2871 but found the power very lightswitch , the bigger turbo lets me corner preboost and in transition then come on as i exit , very controllable, did a 680km run a few weeks ago mainly in our mountains and fell in love even more with the busa and its current setup (build is in here somewhere)..... power difference between the 2871 and 3071 on the 1340cc is more drive forward with the 3071 wheras the 2871 drives up , turns a nice bike into a pogo stick ....
Somewhere in my shed is a 1k for drags , 68" gt 30 ice cooler ,slider clutch , actually thought about selling it lately, don't get enough time to ride my roadbike much less get to race meets , my local track is about 1 1/2 hrs from me , best time so far on a busa at 8.4/ 177mph was hoping to get the 1k into the 7's

Going to try and get some testing in at an airfield or maybe up at Lake Omeo before sending it to the US as its easy to make a poor handling bike putting this much area at the back

Not much luck with land speed race meets in Australia lately, it seems it's almost a bi-annual event now.

Yeah we have to find alternate venues
Lake Omeo looks promising, and its close , only be limited distance but that has worked for the guys raceing at El Mirage for 60 odd years so i can't see why it shouldn't work here too , Noonan has top bike speed at El Mirage at something like 252mph on a 1.3 mile long standing start dirt track , and i have run 201mph there, with more in it :)
