question on porting

[AJSTANG]

93GTDin: My motor combo includes twisted wedge heads, cobra intake and lunati cam (equal to TFS stage I). This engine in my 93 GT conv yielded 12.8/108 mph. In avg weather I ran low 13's @107. You could port the heads for a few extra ponies, but I recommend that you rebuild the AOD with a higher stall converter and 3.73 gears or swap to a T-5 if you want to run quicker.

My car too did not run well after parts were initally put on and often stalled. It also felt very sluggish on the low end. The initial reason I got from the tuner was the old excuse of "the computer needs time to learn the new parameters." I took the car back a couple more times. Turns out that the TPS sensor was reading > 1 volt. I got this readjusted to less than 1 volt and I no longer had the idling problem. The low end sluggishness was cured by adjusting the timing to 18 degrees initial and fuel pressure to 45 @ zero vacuum. At the track, the mph went from 103 to 107 in the heavy vert. I now trap 109 with this engine in a lighter coupe.


Chunkfunky: The TFS street intake is worth an additional 10-20 hp over the stock Cobra intake; good power up to about 5500. The TFS track heat makes power up to 6500. I think the TFS intake, stage I cam and twisted wedge heads is a good package. Based on info from people who have this combo, the power figures are 290-300 rwhp/315-325 rwtrq.
