hey guys im running 8.3's @ 83mph right now. the truck is almost stock aside from my custom turbo set-up @ 10psi

im looking for ways to get my trap up to 86 or 87mph.......

@ 8psi my trap was only 80mph. do you think by upping the boost to 12psi i could get another 2 or 3mph out of the truck

also what a shorter 3000stall torque converter?
Shorter tire?
someway to move the power curve up in the rpms a little? (e-fans?)


any help would be appreciated.... im happy with taking down stock Fbodies and stuff like that but i would like to start getting into faster car territory which is why i need a better trap..

thanks

Shorter tire and lock your converter earlier.

Do you lock your converter in the 1/4? I thought you werent suppose to?

also i have a 31" tire. and heavy *** wheels and tires. going to a shorter tire and a lighter wheel/tire combo would that help with mph @ all?

Going lighter will help.

I do. I experimented with various lock-up points and for my application, just after the 2-3 shift is ideal for a good balance between MPH and ET (for me).

add about a 75-100 shot that would help

A lighter wheel and tire combo will help some. What gears are you running? Most turbo cars like tall gears.

it all depends on the hp curve and where you are shifting and where u r crossing the finish line if shorter tires will help
