What am I lookin at in the 1/4 mile?
 

I have a 91 Gt 5.0 and I have flowmaster cat-back,9mm wires, mac headers, off-road h-pipe, TCI street fighter aod tranny, stall converter, trans cooler, Racecraft springs, saleen lower control arms, g-load brace, strut tower brace, 4 wheel disc brakes, 3:55 gears, aluminum driveshaft, removed ac, Edelbrock performer 5.0 Intake ported, fpr, 190lph fuel pump, with 245/40/17 tires and 235/40/17 in the front. I'm just curious on what my 1/4 mile time and mph would be. Thanks everyone

mid to low 14's @95-97mph.

IMO,

Get rid of the stock heads, pick up a 65mm tb, a new maf, and you would be in good shape, Maybe an e303 cam too. - John

Does anyone think I may be running high 13's like 13.9 or 13.8. Thats what I've been shooting for, I do have that manual valvebody on my tranny, whoops I also have underdrive pulleys.Thanks again

I wish you the best of luck at running 13s. But, the only one that can tell you is the track. We can have fun guessing. I always answer this question with this answer, Their are too many variables, you have to go to the track and find out.

If you had 4.10's and sticky tires 13's would be easy. Almost everyone is disapointed with there 1st trip to the track.

Like 88workcar said, There is one way to find out.;)

Later,

Uuummm for fun I'm gonna guess 14.4@98mph. Yeah alot of people are disappointed their first time to the track, but I wasn't! My 14.331 was very suprising to me.

Stiff suspension and 17" radials are gonna hurt you (I speak from experience). I've got more breathing mods and a lighter car and I could only get a 13.8 @104.77 as my best street tire run (2.199 60') with a set of M/T sportsman pro's I got a 13.34 @ 103.6mph and a 1.90 60' and I no longer had to granny shift second like with the street tires.
My prediction is that your car will run 97-99mph and the ET I won't touch.
