Just bought an 03 Cobra. All I got for documentation was a dyno sheet (~480whp). I was told it has a 297 Scat stroker (~3k miles on rebuild), with a comp cam, 80lb injectors, long tube headers (no cats), JLT intake and MAF, not sure on pulley size but was told it made around 12 lbs of boost. Might have some gears in the back as the speedo is off.
Only issues right now is that its running pretty rich, and the ABS light is on. But I want to fix the rich issue and it definitely needs to be more quiet. So I have a couple of questions:
-What mufflers can I install on the end to make it the most quiet? (I want to put cats back on to help make it more quiet too)
-The car came with smaller injectors, not sure what size, but if I swap the current 80lbs for something smaller, will it require a tune? (maybe this will help with the rich afr?)
-Anyone with experience on Scat strokers know the ideal oil viscosity to use? (I live in Phx, AZ so temp ranges from 25F to 115F, so I was thinking 5w-40)
-Is it normal for the transmission to become a little more noisy after some driving?
-Recommended shop that can tune my car for drivability? (I dont have all the specs for the engine, so Im not sure if that would pose a tuning difficulty, but it makes enough power as is, just want it to be more tame)
