I did a compression test on my 87 T yesterday, looking for the source of why my car is not making the power I think it should be making.
Compression was 80 psi on all cylinders. Test was conducted with all spark plugs out and throttle open. I thought maybe the battery was a little weak so I hooked up the battery charger and did a second test. Same results
. shouldn't compression tests on these motors yield around 120-140 psi? The car starts fine and runs great I just thought that the car should do better than 11.70 @ 117mph 1.70 60 ft. with thhis combo.
.030 over 109 block ,champ. irons,218/218 flat tappet, 72 lb. inj., pt71gtq, pte front mount, accufab 70mm plenum/tb., walboro double pumper, 3.5 THDP, 1.6 roller rockers, accufab FPR, FAST ecu.
2 months after those first E.T.'s the car still runs 11.70 but mph is down to 114!!
I will be checking camshaft soon, any other inputfrom you guys would be great!!
