the only dynoed 1.2 bar run I've ever done made a mediocre 430-ish hp at the wheels, redlined at 7000rpm. The car makes power through 8000rpm, and well, if you've got the balls and the map to turn it up past 1.7 bars, you'll make a lot more power I'll tell ya that :)

1.5 bar is next on the list with some 800cc injectors. not yet though pointless in this weather lol.

my wheel power peak with boost and afr curves

This was from my old R32 @ 1.2 bar, built by Rob & Justin.

2530 turbo's
1st sheet is on 1,28 bar (peakboost) when we were setting up for early response at a longer range.



This one is at 1,72 bar of boost. same as first one but then the final result at that moment on the same turbo's.



still 2568 cc standard block, standard internals. On E85 bio-ethanol.

looking good peeps, nice few results here now :thumbsup:

for 18 psi boost pressure these are some good power outputs imo. and all above 400 lbft :clap:

ive looked into this since i started this thread and the compressor maps give us a good idea. the center curve of the map is a good reference for boost - airflow.

1 bar 500 hp
1.25 bar 550 hp
1.5 bar 580 hp
1.75 bar 610 hp
2 bar 630 hp

if im correct i should see a GENUINE 600 hp at 1.7 bar.
