Dyno Graphs... *56k beware*

That is REALLY nice, my friend...really nice.

Nice graph. You have about 15 hp hiding in there with some good tuning. Your a/f chart is way out of whack.
Get that fixed and you will have more power not to mention better overall driveability.

Good numbers. its crazy though how much your tq drops. blast that intake. My 2.8 is only making 190 peak hp on the dyno,
but at 6k rpm we have about the same tq numbers. Its my intake though. My tq doesnt' start to fall till 5k rpm. Peaks at 3700 or
so at 190 lb ft and holds till 5k rpm/ Mine is right aroudn 150 lb ft at 6k rpm which is where yours looks about.

OMFG. You have NO idea, Shaun! I'm porting the base, and middle plenum sections, and building a new, bigger plenum with a 62mm throttle body (stock is 52mm)

Sweet. That should add a decent amount of power at the same boost levels. Basically you want to
shorten runner length and add more plenum volume to gain more top end.

My intake displaces more liters then my engine does. I basically elminated teh stock Fiero upper plenum
and went to a dual tb setup. One manifold per bank of cylinders with a tb feeding both cylinders.

62 mm tb will really help out too.

GEt an SAFC fuel computer and tune your fuel with that to a better a/f ratio.

I also suggest upgrading to a 20g wheel for a bit more top end. It will flow more at the same boost level as a
16g wheel and is also more efficient at the boost levels you will be running on it.

These mods with a good tune and same boost should put you close to 270 whp peak.

20g? Nah.... T61? Well, ok.

[Guest]

I mentioned 20 g cause it will bolt to your flange. It has the Mitsu flange like the 16g so it would be a easy swap.

A T61 would need a new flange. Which is no biggie if you dont' mind some flange modifying.

*grins* I built this entire kit, from scratch, from the ground up. I also built it in such a way, as that swapping turbos only requires 1 small pipe change
