Craig Mack said:Another very good question. Shifting too early can knock off at least a couple MPH.

5800 was too low
and 6200 seemed to lose power
I admit I need more seat time as this is my first 4.6L
I think the car will go 8's as-is
And it does need to be dyno tuned very soon 95000miles on it

I have very similar mods on my 98 Vert and I hit a 13.2 at 104mph at a track at nearly 3000 feet altitude with 3:73's.97poonstang said:sounds like there are some driving issues here. Put some drag rads on and dump the clutch @ 4500-5000, your car will hook up! Also lower the psi on your tires to about 12lbs for better traction! My fastest 1/4 is a 12.97 with what I have listed....all smiles
I also think it would be a very good idea to take a look at IMRC's on this car. With a 60' like that it sounds like it's running flatter in the higher revs than it should. If they have never been cleaned it's a good chance that they’re clogged on this car killing its high end power.Craig Mack said:98mph trap? Ouch Maybe you need a tune up?
