New member - GSXR1100 mechanicals interest

[jmw76]

Hi All,
Just a quick note of introduction.
I have a passion for Suzuki GSXR 1100 motorcycle mechanicals.
So much so, that I have a little race machine that is GSXR powered.

Not exactly a street fighter, but I guess in this small world this is benefit in sharing knowledge about these old engines across disciplines.

Maybe later, I would like to build a street fighter. I have always admired the GSXR derived ones (Harris frames, etc).

Cheers

Peter.

That is mad. I would love to make a road based quad around the same engine or similar. I have a spare 750.... but I couldn't register it in WA.

[DCRacing]

i saw something similar do a couple of laps around Morganpark once they have some serious mumbo and stick to the deck unbelievably well.
Were are you based Peter, i am racing a 88 gsxr1100 in a 1990 frame, i can't take any credit for the engine performance tho, but i am building another couple of engines to run and see how they go.

Welcome to the madhouse Pete [}:)]

[jmw76]

I am located in Victoria.
My car was originally built by a guy in QLD.
I do 1:46 around the island and 1:35 around Winton here in Victoria.

Mods to my engine include:
- 1052 engine
- Wiseco 81mm pistons
- mild cylinder head porting and skimming (13:1 comp)
- RS40 carbs
- custom headers (38mm tube)
- std cams but timing set to 109/106
- runs on pump fuel

Not sure of power output. I estimate 150bhp + at crank.

Pulls hard out of corners.

Cheers

Peter.

Shithot ... must get me one just for midnight runs up Mt. dandy ...
Welcome .. i might know a guy who can get it on a dyno for you if you ask nice ...

theres a bloke up here on the Sunny Coast with 1 of them things,but its got a turbo Busa engine and 450RWHP. He's also into hill climbs,but has had it out at Willowbank...could only do 8 seconds coz it couldn't get traction.they wouldn't let it run again without a chute.
welcome

Might be worth a look if you wanted restricted Rego in Qld in trying to get it registered as a UD category vehicle - UD = UnDefined same as forklift. Your local Qlde Transport will be able to assist you in that. Or alternately under a club rego perhaps?

I love the Turbo Busa Idea though...

Welcome aboard mate, looks like good fun

Hi Guys,

Thanks for the interest.
It's not so much about shear power.
It's all about how you use it on the track.
I haven't got bags of power to play with and I am pushing quite a bit more weight (340kg) and more frontal area (drag) than a bike and yet I can wip the arse of many bike riders around the island (except of course for the out and out racers).

I wouldn't mind getting the car on a dyno one. I would be happy to share the results with all that are interested.

But first I need to do some repairs. I have a broken gearbox that I need to fix. Currently I am having a little difficulty finding good parts for it.

Cheers

HEY PETE I WAS LOOKING AT A 1216 IN US. sposed to put out 162 rw
much the same specs- stock cams , i was thinking about running 109-110 ex as well on my 88-1100 mayeby 108-110 inlet to move power
out of the mid range a bit with the 13:1 1216cc ,stop it from being such a nuisance trying to wheelie in the middle of corners, bloke on gixxer.com claimed his ran hot with 110 ex centreline?

[jmw76]

Yeah, it would be really nice to stick mine on a dyno one day and see what it really knocks out.
BTW I think my cam numbers were around the wrong way. Intake centre = 106, exhaust centre = 109.
I have played around a bit with timing and to be quite frank have not really noticed a lot of difference (at least to lap times anyway). I also run bog standard ignition timing.

When I have been up against Busa powered vehicles, I seem to have similar grunt out of the turns. I think it is mainly down to skill and balls at the end of the day. There are some vehicles I run against which seem to have a bit more top end. I run out of speed at about 220 and power over 10,000. Just think of what lap times I could do if I could pull 250+ down the front straight at the island. You have to really hang on for turn 1 however. It takes a lot of courage not to lift.

Talking to some Sidedy guys today. That might be fun. But I kind of link the security of a harness to hold me in place in my machine.

I saw a photo of a fighter the other day based on a gixxer. It looked like a stealth bomber and must gixxer bits looked pretty standard. Cool machine.

Power isn't everything. My daily driver/tow car knocks out about 530bhp. A bit more than the GSXR power plant but not as fast. Race runs to 100kph in about 3.5s. Daily driver is only about 4.5 - 5s.

I have only ever run a 1/4 once back in 2003 at Geelong speed trials.
My first ever drive of the race car. Only got one run where I didnt stall at 12.3s.


cheers

Welcome aboard Peter

[BANDITROD]

welcome mate

[old gsxrr]

Pete,whats your daily driver? i have about a 400hp 308 in a 1 tonne-tow/daily driver,i build a lot of engines using engine analiser programs i concentrate on power/economy engines on computor as most of the people i build engines for have to travel a couple of hours to get to bris/sunshine coast etc.308 gets better than 25mpg when i'm not towing and i've got 20 towing a vl group a from sunshine coast to here in murgon -ken

[jmw76]

My daily driver is a supercharged, 6.0L, VZ, HSV Clubsport R8. She gets 10L/100k on a trip. 15-16 L/100 with the trailer and race car on the back. It's a pity they don't build them this way to start with. She's got more grunt than the new W427.
Cheers

Ken, for your interest you may like to look here

BLOODY EXCELLANT,WHAT SORT OF BLOWER IS IT? PEOPLE EQUATE 4CYL WITH ECONOMY ,OLDER FRIEND HAS A FAIRLY NEW HILUX HE USES TO TOW HIS SPEEDWAY CAR GETS 20 MPG BY ITSELF 14MPG WITH TRAILER AND CAR
SAYS FORGET TRYING TO OVERTAKE IFF YOU GET CAUGHT BEHIND SOMETHING,

[jmw76]

The blower is a Harrop unit.
The car really only needs one gear.
The 1st five are just to get you up to cruising speed.
When driving to Winton from Melbourne with the race car and trailer attached, I just slap it into 6th, set the cruise control for 110 and sit back and relax.
You just don't have to change until you get to the other end.
If you want it to feel a bit sportier for the occasional overtaking manouver you just leave it in 5th.
Cheers

Welcome Peter try Suzuki they have good parts for them.
