I went down to see Dave this weekend and run the car on the dyno. I've attached a chart that shows what the car did last spring before the cam and what the car is doing now with the cam, and a couple of other mild mods that will help to support making more power.
In the spring the car was virtually stock except for a almost non ported '94 blower stock 90 sc pulley, a 75mm TB, 76mm MAF, and 42# injectors and she peaked at 221 rwhp @ 4586 rpm's with a 289 rwtq peak as seen on the chart.
Now the car has a cam, a ported blower over driven at 10%, and a few issues. Before I show the numbers here's the issues.
1. A very crappy exhaust system which includes the stock 2-1/4" newer style center section that goes under the tank. This time though the cats where gutted, and there is a chance that that can hurt performance more than the stock cats in good shape, but not proven.
2. When we pulled the blower apart to port it, I got to see the cleanest, most polished rotors I have ever seen ... they looked gorgeous... but 1 problem. This meant that the coating I knew was there earlier this year was now sitting in the top of my intercooler. Almost all of the coating had come off. Now the blower was less efficient and I had a partially blocked intercooler. The good thing though, the porting job was beautiful , so to take advantage of that I need to order up some coated GP rotors.
So with the above in mind and the car running good otherwise the dyno pulls proceeded. (BTW the car was running 91 octane). Because the intercooler was partialy blocked and the blower itself was down in efficiency, the ACT's skyrocketed each run so Dave felt it was better to cut the run off at 4500 rpm's, as so much timing was been pulled by that point the car was losing power.
The car still made 247rwhp at 4471 rpm with a 316 rwtq peak. Thats a gain of 26rwhp .
Because of the issues above we feel there is more in the car and that will show up when I sort out the exhaust, and deal with the rotors.
Also goes to show that you can still have a totally stock looking car that can run pretty descent power and not have to rob a bank to get there.
