Just thought I'd mention it. I'm taking my car down to AFM for a dyno tune this Friday. I'm having them clean up a few other issues, so I'll be leaving the car there for the week, and picking up the following weekend. Any HP guesses with mods in sig?
I'll say 310rwhp. I suggest you grind open your bbk collector. It necks down to under 2.5" at the end of the ball/socket joint. Open it up a bit more to flow better. What other issues are you having?
Install PMS, 3.73 gears, smog delete, ignition amplifier, fuel pressure regulator. That's pretty much it.
I would not be afraid to agree with you on this......with the stick very attainable with a good tune.
I'm gonna say 290s. That sounds like a stout combo, but I don't know if the street heat will give you the RPMS at the high end. Adam
