Stock r32 gts-t boost

[yogi000]

Hey,

I just installed a temporary boost gauge on my r32 gtst which is absolutely stock, the only mod being a redline panel filter. Basically these are my results;

Full throttle in 3nd spikes to 11psi holds 10 psi till about 5300rpm and drops back to 8psi, pretty much got the same result through 2-3-4 gears

Is this normal? only reason i ask is because everyone i speak to reakons all the skylines (r32,r33) only run 7psi but its holding 10psi for a pretty long time, not just spiking upto 10.

Your feedback would be appreciated

P.S done on a 15 degree night.

My gtst and 4 both ran 9psi bog std and would hold that boost, with exhaust and a panel filter that increased to 11psi and didnt drop off. Have to checked to see if your i/c pipes are all on tight?

hey man i have hks pod and cat back exhaust and mine runs 12psi up to 5000rpm then runs out of puff and sits on 10psi all the way to 8000rpm. i have not touched the boost....

im keen on mesuring the intake temp as i reccon the stock cooler isnt doin much now so when i put my new fmic on in the next week or two it should make a bit of dif.

hope this helps a bit

When Mine was stock it ran 9psi of boost.

After the 3" turbo back exhaust it now runs 10.9psi and doesn't drop off.

If I run over 12.5psi of boost it will drop back to 12.5psi over 5500rpm.

I have since redrilled the holes in the wastegate bracket and pulled the wastegate towards the front of the engine bay effectively reducing its travel. After a little bit of fiddling and some nasty boost/afm cuts I've got it holding 16psi until just over 7000rpm where I grab the next gear.

I've also used a gated bleeder to bring boost up a little quicker in the mid range. With just the bleeder as I said it will drop back to 12.5psi.

By doing the wastegate mod it dropped my 0-100times from around 5.6secs to 5.2secs. I can get it doing 5.2secs to 100km/h consistently. Providing the road surface is nice.
