Before I got the blower and with only the exhaust I had dynoed at 240RWHP and 279RWTQ (SAE)
After I added the blower I gained:
+123RWHP +83RWTQ (SAE)
just from the Cobra Killer Kit.
Which puts me at:
363RWHP and 362RWTQ (SAE)
I then added a Paxton Intercooler, Steeda Powerpipe, 3.3 RR pulley, Vortech Mini Race Bypass and a new tune(required). I also swapped out my 30lb injectors and upgraded to 42lb injectors.
My new numbers are 384RWHP and 373RWTQ SAE with a T&J mail order tune.
The "blimp" in the a/f at around 3,800-3,900rpms was NOT the tune...the a/f machine had a brain fart or something lol and that's why it spiked rich for a sec. My other a/f pulls that day can confirm that.
