Since I got my engine finally running well after a summer of oil leaks and head gaskets I got my car on a 4-wheel dynometer. Evolution Motorsports of Tempe, Az., offer a $60 special the first Thursday of each month so I stopped by. My car is now running the following: Mance SXTB, RS3 MAF, HVRS with my own Samco silicone hose kit and a ported and polished intake manifold. I wasn't sure what to expect, I do know that the stock 12v engine puts out around 120 whp and I had at least 25 or more h.p. over stock.
The guys at Evolution strapped her down and did their best to calibrate it. A couple of issues: they couldn't get a pulse from the coil wires and their OBD 2 cable wasn't long enough so they had to calibrate things in a different way. I'm assuming it was accurate, they had the weight and other model-specific criteria in their database.
Did 3 pulls up to 5500 rpm and here is the best run, 151 whp (all 3 were within 3 h.p. btw):



The tester commented that with the auto box it was hard to get the car up to full throttle without having the transmission wanting to downshift. Power-wise I feel I've gotten pretty good results with all of Mance's mods, a solid 30 h.p. gain. Perhaps with a different exhaust system and AAH cams I might get a bit more. I'm curious if going to redline would have made much of a difference..?
