Just like Joe said after a high HP build it's all a matter of putting that on the ground. I was not able to keep the car on the ground on higher boost levels. The car was happier with two people in it

 

Art,

Explore the "Ramp" type front diff. It will give you the capability of transferring a lot of that wasted power to the front tires.

 

i wonder what rims/tires setup u r using guys!!!

 

Not that I'm one of the "fast" ones, but I made my pass AWD with 19's. I had Nitto INVO's in the rear and PS2s in the front. My pass was a very lucky pass because I got the boost just enough on the brakes as to when I let go it spun VERY little on the initial hit. Most of my passes on even higher boost ended up with me almost hitting the wall if I tried to stay in it or having to just let off almost instantly. I never made a pass on my 27.5" Drag Radials (on 16's LOL) and my front runners. I think I can make a 2nd-3rd gear pull and get my 60-130 down because I go right into boost in 2nd gear before 60. Plus with a 7800 RPM rev limiter I think I can nail it right at the end.

 

Nail it with out a 3-4 shift?

 

Yup, taller tires (1.5" taller almost) and big rev limiter help out a lot
