Engine boost at what rpm?

julian · Post by **julian** » Thu Oct 18, 2007 10:56 pm

Similar to steptoe's thread below on engine rpm at a certain speed, I was wondering at what revs people are getting full boost running an EA82t?
I have stock boost levels with only mod a 2.5" exhaust all the way and I get a full indicated 8psi at between 2000-2100rpm.
Others?

Yeah that sounds about right, only mines only at 6.5 psi

I would check the accuracy of your boost gauge.
At 2000RPM it should be just coming on to boost. I.e. 1 to 5 PSI

I am pulling a full 11.5 PSI @ 2000RPM due to my redesigned 'Up' pipe....

2000-2500 rpm but i wont know till i weld up the manifold and replace the missing studs in the turbo and re fit the intercooler lol but i think from the previous owner it was running full boost at 2700rpm 11 psi

Fair enough...

I'd like boost on my car, but i think this will always remain on the wish list...

I cant see the problem with that, at about 1900 the needle nudges just past 0psi and by about 2200 there is the desired 6.5psi

11psi at 2k, so at what point do you start building boost? (please say idle;))
One of these redesigned uppipes might be worth a go

3500rpm and 17psi

It rolls past the 0PSI mark at about 1700RPm

thats a little bit different to when u mentioned this

WOW! The new pipe makes a HUGE difference!
It now pulls 4-5PSI @ 2000Rpm!!!!

Xtreme_RX · Post by **Xtreme_RX** » Mon Oct 22, 2007 7:39 am

4-5PSI @ 2000RPM is with the boost tap closed (max boost 7PSI)

11.5PSI @ 2000RPM is with the boost top open
(Unrestricted waste gate action till 11.5PSI)

Big difference between 'factory' & 'Open'
