Hi Glen.

Personally I wanted to know what the preferred boost pressure is, what the maximum reliable boost pressure is and how reliable the turbo's are in general. e.g are they weak anywhere in particular etc...

cheers m8

1.5 bar is the most I am aware of , however the Ozzy touring cars (GTR) ran 1.7 in practice I believe.
I have never seen more than 1.4 from mine , but never really tried as I know the afm's will max out.
The chap I got mine off used to consistantly run 1.5 bar and made 380 wkws, he had 300 zx afm's so he could ....

hi glen v good power on that boost, whot boost was used on the red power curve, cheers. D

GT-R Glenn · 9th October 2005, 08:45 PM

Im pretty sure 1.3 bar in that graph , I thought we did run it on 1.4 but it went back after the initial tune to iron out a miss and I think the second time we ran it we tried 1.4 and 1.5...And thats definatley the first tune graph...

Nice power, true. Bear in mind the tcf value if comparing to other dynapack graphs though as each may put different figures in there.

I could be wrong (please correct me if I am) but is the tcf a correction factor to compensate for transmission losses?
