Kind of odd that my torque and HP are almost identical... but here it is.
I had the owner of Horsepower Engineering (11950 Perry Road Houston,TX 77064) tune the car also.
Their standard rate is $75 for 3 pulls, or $400 for tuning. The guy knows his **** and learned MS in about 15 minutes. End result of the tuning was an increase of
He leaned out my top end considerably from what I had in my map... he also added in about 12 degrees of timing just about everywhere. No knock, spools much faster, and I'm pleased as hell.
Seemed to make the best power at about 12.0:1 @ 10-12 psi.
THINGS THAT ARE HOLDING ME BACK:
1) The turbo isn't able to hold 12 psi all the way to redline, this is why the dyno stops at 6500, i wasn't making any more power past that. Boost dropped off to 10 psi around 5800-6000 rpm
2) 2.25" cat back
3) 2.5" downpipe
I'm working with Begi now to get the downpipe issue resolved. The catback I might be getting from AK if he parts out.
I'm hoping that those two will free up the turbo enough to make it breath in the top end. If not I'll get a to4e 50 trim t4 compressor before long.
nice work. that .48 a/r may be the determing factor of that power curve more than the exhaust is. the exhaust will probably improve spool but not so much top end. top end on your setup is probably limited by the small A/R turbine housing. I love that hump at 3500--I bet it feels good in real-world driving.
bigger turbine (higher a/r) would make it a bit more laggy, yes, but the topend will improve significantly. freeflowing exhaust will improve spool as well as topend, but the topend improvement will not be nearly as big as with a bigger turbine. IMO
Dang. I came within inches of buying a .48 today, but held off while I pondered the power roll off. Actually, I still need to check out the 1.8 that's destined for my 92. It's nice to know that the exhaust took care of the restriction.
