What Rpm Does R32 Gtr Start Boosting?

[lang]

driving along the freeway at 100k's and hour i make 2-3psi at 2800rpm (this is very slightly uphill, crusing at constant speed, without full acceleration)

Is yours stock? i don't think i make any boost at 100K in fifth. The standard boost gauge is also really bad so i might change that first and see. If only money was no issue :

its got stock turbos and dumps and intercooler, its got a cat back exhaust and hks airpods, so that might make it boost a little earlier that a completley stock car

I make 15psi by 2900rpm in 5th gear! Thats a full exhaust system on an R32 GTST with standard turbo, before the exhaust it would of been more like 3500rpm for 10psi...

Thats just an example of what a free flowing exhaust can do

Jazza08,

This is a rb26dett thread.

Unless that is you run an rb26dett under the bonnet.

Yes i understand that completely im just trying to show an example of how a free flowing exhaust will help boost levels come on earlier as that was what the original question was about

Sorry if its useless information lol

i did a little test today because my car has a peak hold function on the boost guage

at 3000rpm exactly in 3rd gear my car makes 4.7 psi on a flat piece of road

looks like i'll be getting a free flowing exhaust soon then

What does a RB26TT run standard boost wise? is it around 10 or 12 psi?

I'm asking this because once the exhaust is in, the boost will creep up 1-2 psi anyway so i don't need a boost controller. I don't want to run more than 14psi on the stock turbos.
