Good luck for saturday mate. Hope the test ride goes well
Well I got it all back together and figured it should start sweet and burn off the extra oil laying around and I can take it for a run WRONG :([V]:(
I notice when I rode into the shed last time that it stalled out and I did hit the starter but it didn't fire back up but I was more worried about the oil then.
Anyway after check everything including spark with a test plug, then thinking maybe I have fucked a ring or 2 ( but I would have to be the unluckiest person on earth)then checking everything again I pulled the plugs and check them and they are arcing onto the insulator (WTF) or at best across to the thread not the ground electrode. New NGK spark plugs about 20k's old but failed :(:(:(
Try to find some tomorrow what Plug do you guy's recommend ??
NGK CR9E. whenever you over oil the system it'll foul the plugs. when i first set mine up it happened to me more times than i can remember. you can use CR9EK's (double electrode) but they're more expensive and chances are you'll foul a few sets before you get it right.
Thanks
Had the CR9E in will grab some more tomorrow and ebay myself a box or 2 next week ;)
Pav was saying that he read you spaced / aligned your plugs so that the spark was protected from the incoming air/fuel. Was that any help ?
it did seem to help the problem but it didn't stop it all together. it is a fair bit of fuckin around though. the main problem was probably the oil fouling the plugs. it used to get blown through my intercooler and would take forever to clear. i don't know if you saw the pics of my bike, but it has an oil cooler under the turbo. it serves 2 purposes, cool the oil and act like a sump so the oil can easily drain from the turbo.
Did check that out earlier. I was thinking of fitting something like this to cool the oil

Just gotta track down the correct size
Over rich and oil contamination will quickly make a carbon track and cause misfire
just as easily as too lean will burn aluminium , and if you ride it on boost to the point of a lean miss this can happen very quickly .
be prepared to replace plugs often while your sorting it out , std type plugs or the twin ground strap type , but don't waste your time with iridium , they just cost more and don't last any longer in this circumstance .
New plugs and it runs. I have noticed that the fuel pressure spikes upto 10psi when the boost comes on (hard to watch and ride at the same time)gunna put a restrictor in the ref line to try and take out any pulses see if that helps. anyone got any idea's?
Forgot oil seems OK for now did a couple of runs and no smoke or oiling up :)
Is it a rising rate fuel pressure reg? If it is, the pressure is meant to rise with boost.
1:1 but it seems over the top at 1 psi boost fuel spiked upto 10psi fuel then dropped to 5 then to 8 etc just seems all over the place like it was seeing pulses dunno. Will try again shortly
What reg have you used? Have you got some sort of way of telling what your afr is while doing these tests?

Aeromotive 13301 - Universal Bypass Regulator
No AFR mter as yet hope to get it soon.
Did a comp test and was getting some strange readings 3 below what it should be and one a 1/4 down on those again so dropped out the motor and striped it down. Was going to happen anyway at some stage so may aswell be now. No major failure couple of good marks in the bore and by the looks of it some monkey has had it apart previously broken 1 of the rocker bolts and other tell tale signs.
Going to google options now for rebuild kits and the like. Should I look at turbo pistons or standard with a base plate?
Is that a Efi reg or low pressure. Might have issues controlling such a low pressure
fuck you work fast. plugs in, test ride,compression test, engine out, strip down and all in one day. you'll probably wind out the day with a shit, shower and shave and then even hit the mrs up for a quicky.:D
Deano those regs come with 2 springs , efi and carb ,
Where are you taking the pressure signal for the reg from ?
Depends on the quality of your pistons, on my gsxr 750 i get std pistons HPC coated and use a 2mm spacer and there lasting well to 30 psi. on a streetbikerunning to 10 psi i would probably just stick to a 1mm spacer .
i had stock pistons with 2mm spacer on the zxr. it ran 18psi boost. the gearbox failed before the pistons. on my zx9B motor i have the HPC ceramic coating on the crown and teflon on the skirts. it seems to be runnig fine.
I am thinking standard with 1.5mm spacer. What was it like with a 2mm spacer off boost.
As Booster said dual pressure I have the low pressure spring in.
I have the ref line 'T' into the small pipe across the throat of the plenumm intake.
Ok what about wastegate pressure reference ? and what sort of wastegate (probably pictured and referred to somewhere )
You can add to a 1mm spacer with std basegaskets, the 2mm on mine realy kills the bottom end , and with the big turbo and hi gearing i mean KILLS...
this vid is with 1mm spacer when i was running methanol , just to get an idea http://www.youtube.com/watch?v=bRNWt_yGTAI
Who make up your spacers? What material is best?
Wastegate comes from the snail and is standard factory built in to the turbo
