How Am I Reaching 10Psi?

[El Chilli Dawg]

Okay guys just recently bought a series 1 r33 and recently installed an aftermarket boost gauge which reads about 10psi.

I sussed out through the threads and judging buy what my stock gauge reads it converts correctly.

What bugs me is that im pretty sure the engine is near factory all I have done to it was install a podfilter and just a regular canon (came with car)

Shouldn't it be reading around 7-8psi? I thought that was std factory?

let me know your thoughts.

Pod filter gets the engine breathing better, will free up a bit more flow. Cannon wouldn't have made much difference but probably wouldn't need to. The gauge is possibly a little bit off as well so it's not too much of a stretch for the pod to have freed it up to about 10.

Otherwise are you sure the previous owner didn't install an RB20 actuator on the turbo, they are a 10psi spring.

Pod, intercooler and exhaust always allows more flow. Mine had trouble staying under 10psi like this.

Get a powerfc and a tune, and you'll be fine.

Freer flowing exhaust (maybe), pod and anything else that makes it flow more than stock will make it run more boost. With a straight through exhaust, FMIC and pod on my rb20det it was running 13psi with no controller.

Cheers guys I'll suss it out more detail. I just want to the know the exact current psi im doing before I increase it more with a EBC lol

Does your EBC not show you?

If your using a EBC tapped into the right vac lines it should be pretty accurate.

At stock boost levels the pod filter wont raise the boost. It will be the exhaust doing all the work.

[Rolls]

he said he only has a cannon so stock exhaust

[gotRICE?]

Oh right, so he did.

Still, stand by that statement though

Have run back to back with stock aitbox/pod. zero difference.

But back to the other thing i noticed.. raising the boost with an EBC and having a stock exhaust? Interesting way to do it dont you think?

[Manuel Kasko]

Yeah fix your exhaust and get a FMIC

Then worrie about the EBC

Plus a $50 bleed valve will do the job for you if your not looking to mod to much

Well it obviously depends on the pod/panel filter/etc in use, but I've definitely seen just a pod filter free up 1-2psi before.

I suppose if you're comparing an 20 year old stock filter maybe. I did an Apexi pod vs an Apexi panel.

Lets not forget that parts like split fire claim huge gains too.

[Hanaldo]

Oh yeh for sure, I'd have rated the apexi panel over the pod, interesting that there was no difference. I imagine that if you had done a few full load runs then left the car to sit and heat soak, there would have been a bigger difference.
