New dyno numbers for my turdbo 1991 Civic Si.
First of all, I want to give a great big THANK YOU to the guys at Dynospeed in Memphis, TN for setting up the dyno day today for our local forums, Memphis Racing Scene. It was really appreciated and I know the coolers of drinks were a great addition as well. Keep up the great work, guys!
My long term project car has been giving me fits for the last two days trying to get it ready for this dyno day, but it actually made it. I know I wasn't the only one who was shocked to see it actually in the parking lot, then eventually on the dyno, just because of ongoing, nagging issues.
My previous dyno tune on the car was with a less than adequite water to air intercooler setup. It was VERY undersized for the application, and it shows, now that I have new numbers to go by. The best run on that setup was 264whp/193wtq. A pic of that old graph can be seen HERE. I upgraded to a Precision Turbo and Engine "600 hp" model intercooler; their mid sized core. It fit very well behind the bumper with some major bumper support modifications (done by Polk Performance. Thanks, Don) and some very interesting piping. Somehow it all fits in the engine bay.
The car didn't feel all that powerful on the way to dynospeed because of the temperatures, I'm sure. I guess I'm just used to it, because the results definitely put a smile on my face.
Here's the new dyno plot:
325 whp / 226 wtq (the 261 wtq was a fluke on the reading)

And the car, for reference:

This intercooler upgrade was the BEST dollar per horsepower mod I've ever done. I have roughly $900 in the intercooler, piping and labor, and it made about 60 more horsies AT THE WHEELS at the same boost pressure as before. Not a bad investment at all, eh?
With a bit of tuning to get this down to a 12.5 a/f ratio, and some releif from this HEAT, I can see 350 whp being not too far off in the future.
Engine Setup:
Stock b16 block overbored .5mm
STR blockguard
Eagle rods
Endyne/Wiseco pistons
Stock head
GSR cams
Strength matched stock/ITR valvesprings
ITR Intake manifold
JG 64mm TB
Inline Pro manifold
Precision Turbo SC34 turbo (.57 trim, .60 a/r compressor; Stage 3, .63 a/r exhaust)
Precision Turbo "600 hp" Intercooler
35mm TiAl wastegate w/ open dump tube
Precision Performance Custom 2.5" to 3" downpipe
Thermal 3" exhaust with test pipe
15 PSI
Thanks for reading.

Like I said in this thread, the engine bay is a mess. I know this. That is one of my future projectzs. I just wanted it RUNNING first, y'know?

Here's a video of it on the dyno. Sorry for the size, but it's a local forum's dyno day, so there's a lot of cars in it. My car was last.
