I swore i remember a mph chart for 4.10 gearing with our bullitts on this site but i cant locate it. Does anyone know where to find it? I am trying to figure out what my mph would be at the top of 4th. I want to play with the numbers a bit so if I could get a baseline I could use a formula and play with tire sizes to see what would be needed for the track. Thanks for any help!

With 4.10 gears and 275/40/17 Nitto DR, you will hit the rev limiter at 111.1 mph. Been there, done that.

275/40/17 Mickey Thompsons going on today and to the track tonite.

Thanks guys. I knew it was on this site somewhere. I found this site which has every calc you could want.
http://www.wallaceracing.com/et-hp-mph.php

Also there is an awesome spreadsheet on modular depot that you could change all sorts of variables to calc inj size, mass air, air density and mph. It is a excellent apreadsheet. I recommend everyone to download it.
M&H has a DR that is 275/50/17 which brings tire height to 28 inches which would allow me to see up to 140mph. i will need to have these if I choose to hit it with a 35 shot of nitrous on top of my D1SC. I may get kicked off track tonite. Hopefully they won't notice i don't have a cage.
Tonite the drag strip by my house Island Dragway in Great Meadows New Jersey has a barbecue and cruise nite for $10. The first Wed of each month $10 to eat all you want Chicken Barb and race. You can't beat that!!! Gates open at 4:00pm and race til sundown, barb til late. Anyone in northwest NJ area come on down...

I disabled the rev limiter and will be seeing 130+mph hopefully with the 4.10 and 275/40/17 Mickey Thompson DR's. Will see I know I can get it to about 125mph but am not sure if I will run out gear unless I bring it a little past 7000rpm.
