thanks SPEED 16.8@81... 60ft- 2.59

 

If you've got a 5 speed I'd say you should definitely be in the 15's because of the headers. If it's an auto I don't really know, those 2.77's really kill your E.T.'s.

 

I'd definetaly say you should be in the 15s. My 89 305 TBI w/ only a cat-back and Jet Stage II chip ran 15.7 @ 86 MPH. That was with 3.08s and an open rear. Granted this was done at MIR, which is just a little above sea level, but you should still be in the 15s.

I think 30 hp is a little extreem of an estimate. Without a cam change to match that intake your not going to see that much. I think what you will see is an ability to breathe in the upper RPMs and a slight raise in yout TQ curve. I would assume aroun 20hp, but if you could bump up your fuel 1 or 2 PSI to match the added airflow you will have you might be able to get that 30hp

Past Thirdgen:
86 Trans Am w/ built 355TPI with SLP goodies and too much other stuff to List. One sweet *** car, wish I would have had a good enough Job to pay insurance on three cars so I could keep it, but for a 89 Turbo Trans Am w/ Low miles, I think I made the right choice!
