I dont think you will pick up MPH as an auto will dyno less but you will pick up et for sure.

With the 400 and tbrake, you can do 1.5s all day long on a decent tire....faster on good tires. Here is a little info for you
9.5 psi...launch off idle and turbo doesnt spool till after 60'.....1.98 60'.....kinda equals the type runs you were making with the easy launch
11.32 @ 131
right back in line and launched off the tbrake...no other changes...
10.29@ 132 60' was 1.56

now for more info......idle launch...1.98 60'...5 psi
11.47@ 125
only .10 slower than 9.5 psi idle launch and 6 mph slower.....all the difference is that first 330'

All I want to do is hit the 150mph mark for some reason???? I know a taller tire will pick me up some mph,but with that said I also want to feel the g's off the line and see if I can get to pull the wheel's a little!Ha Ha. Decisions decision's!
I will think on it a little,but in the mean time I am going to be pulling some baggage off of it!

screw the mph bro!! you can do that rol racing anytime! you ride with jerry or i once when we launch and you'll forget all that mph nonsense. now after you get the fast times and consistency you want then it's fun to see if you can work out higher mph. see ya at the v next thurs.

Actually a taller tire will lower your mph. 150mph is a hell of a lot of power for a F body. Auto tranny is for drag racing, thats the ONLY reason to own one. Nice car. btw.

So if I go to a 28in tall tire and get rid of my 25in tall tire,I will not pick up mph??I have to disagree with you on this!! I am only 6 mph away from my goal. I think I can do it with the power I am at now!

Every car I have ever seen swap to a taller tire has lost mph. By running a taller tire its just like changing your FD. A smaller tire is going to net you a higher mph b/c your rate of acceleration is greater than a taller one, given that you are not running out of gear due to the smaller tire. The only way that you can get a higher mph with a taller tire is with more power. If your not to the point where your current tire is your limitation, then there is no need for larger or wider. With the power and the car you have, a 28" 10.5" tire should do fine. I mean if the 10.5 guys can put down 2000hp or whatever they are and getting that **** in the 4's and 5's (1/8 mile), I see no need for more tire. At the track, a street tire is going to slow you down and your mph can be higher. Most of the time slips I have seen on slicks, a lower et was always at a lower mph, unless there was the ability to get more power down. If you hook sooner you accelerate sooner, not 1/2 way down the track where your mph will be up. Mph is measured at the end of the track in a box. You cross the 1st beam and then through the 2nd and your distance/time is calculated.

That's understandable! Actually with the 9in. rear i am going to have to get a 3.50 gear. Currently i have a 3.23 gear so with the higher gear and taller tire I should be about the same.
