id like to see the dyno of before and after with the mufflers.
Those numbers came from a member of this site a while ago. I believe it was a Flowmaster Muffler. His 2.8 made 10 hp, and 10 lbs of torque more than it did stock :wink:
The muffler was the only up grade that had been performed.
The 2.8 made 111.5 whp @ 137.6 ft/lbs with the Flowmaster muffler
The car in question had an auto tranny, which uses 33 lbs of torque to drive.
Using this math, we get the following
137.6 + 33 = 170.6 Lbs of torque at the flywheel.
111.5 whp @ 4500 rpm = 130 Wtqe @ 4500 rpm + 33 = 163tqe @ 4500 x 4500\5252 = 139.66 hp @ 4500 rpm at the flywheel
So, thats 140 hp. and 170 lb-ft tqe at the flywheel, which is 10 hp and 10 tqe more that stock.
