Valve Float?....... Next Step?

[mr skidz]

did you compare spring rates?

You can say the statement is shit all you like, but if you actually have a decent engine builder that checks the seat pressure you will find you can't get enough seat pressure without the creating a coil bind situation because they are made to soft from factory

I agree but that's because you chose the wrong spring it's not japan's fault that the spring don't work it's yours.

your statement still makes no sense

we have all used different brand and model of springs and they all have the same issue, it's ok we've made the mistakes and are happy to pass on the information. If you still choose to buy them and then end up paying twice, I really don't care cause I've learnt from my mistakes and won't be making them again

[mr skidz]

Well since you're tomei springs were to soft what are they rated at and what were they measured at, tell me what the difference was because I have some here that I haven't used yet and I plan on checking them before installing them if you are correct then I will bow to your comment

[r32-25t]

We needed 80 pound of seat pressure and when we shimmed them up enough to achieve it they would bind even with a poncam (9.15mm)

[mr skidz]

we're they the type a tomei spring

[r32-25t]

Yes they were

[mr skidz]

tomei type A springs have 52.9lbs seat pressure that's why there to soft for you.

Might have been 60 was 3 years ago, but you're welcome to ask Joey or piggaz about their experience with Japanese valve springs. Make sure you ask Joey tho cause his is definitely a story you'll want to hear

[mr skidz]

tomei valve springs

[r32-25t]

Go fit them I don't care it's not my money, but make sure you talk to Joey and piggaz

[Piggaz]

48 lb on the intake and 50 on the exhaust. HKS Step 2 springs. May aswell have put some rainbow coloured slinkies in there.

[WARLORD]

Lol love it piggaz

lol is that what you had before?

if so what rate springs did you settle for piggaz ?

That's what I installed, yes. I don't know how it got past me but when the stupid thing was carrying on like a two bob tart on the dyno I went and saw the bloke that put the engine together. That's what the seat pressures were. We

ripped them out and put in a camtech single spring and Ti retainer package (which fit SO much better then the previous stuff), put it back on the dyno and issue was gone.

19 psi, 6500 rpm it would float at. Go half throttle it would go to 8000, give it more boost and it would fluff around at 5000 rpm.

Best bit was the camtech package was so much cheaper than the jap stuff, fit as it should and did the job.

Never tested what the seat pressures were as the swap was done in the car. But it went onto hold 30 psi no problems.

[GTR_JOEY]

He went super techs I bought Ferrea dual springs..

Mine have yet to be tested but getting close

[mr skidz]

was it the rates that were no good or the brand/quality ?

[djr81]

Joey, The Ferrea's are dual springs?

[Piggaz]

Well joeys spring broke in his engine and destroyed it.
