288 hp BNR stage 4 dyno
Well I went to the dyno today. I tuned my car for about 3 hours.I first dyno'd around 250 and I was able to tune it up to 288 hp but that was @16 psi and 16 deg advanced (a little too high for me on pump gas)
It just didn’t make the power I was looking for. A little disappointing
My afrs were pretty stable all the way to redline.
I will post the dyno slip as soon as I get to a scanner

man that sucks, i'm sure something was wrong. not saying there's something wrong with your tuning but that just doesn't seem right. i mean people have put down good numbers with those turbos.
peace

what would be aggressive advance for pump gas at 16psi?

uhh boost leaks? I wish there was an easy way to pressure test these cars. A friend of mine with a Vr-4 has this thingie he bought off the forums. You fit it into the intake pipe and hook an air compressor up to it, and then you can hear and feel all the boost leaks.

The dyno graph looks okay all the way up to 6kRPM or so.
After that it gets all weird.
The AFR's drop hard around there, and that explains the drop is power.
It looks like the power was headed to 300 or over that, but you need to clean up the tuning up there.
Was the engine hesitating at the top end?
Old spark plugs?

spark plugs were a few days old. i should probably throw a new set of wires on there.
the AFRs seemed a little tricky to adjust up there. there was no hesitation, it pulled all the way to about 7300 where i hit rev limiter.
i got about 15 ponys from 14 to 16 deg ign advance. when i bumped that to 17 it didnt show any power increase so i droped it off.
i can try to pull a point or two of fuel at 6 grand and then a few points at 65 grand.
