RZMotorsports 20B 4th gear pull

http://www.youtube.com/watch?v=BCO6Ei2X5qw

We were trying to make a full pull in 4th gear at low boost but as soon as 7 to 10psi hit car started spinning the tires. Low boost setting in pump gas is 16psi. Need some drag radials lol.

car has 610hp and 500sh torque at low boost 16psi pump gas but tires started spinning around 7 to 10 psi. At high boost car made 831hp 710 torque. Speed I don't know didn't look car gets loose so wasn't paying attention to speed.

Car is loud you wouldn't hear it u only feel it. In the previous pass my friend 1bad20b was recording I think and I didn't eased in the throtel just punched it and car started to change lane to his becuase tire spin. He was next to me.

Maybe it is the tires. I really don't have the same problems at 560 whp in my 20b. At 7-10 psi, you're probably only 450 ish. The proper tires shouldn't be spinning....is the road cold? That could be the problem. I will say you are making a lot of tq though.

it's been a long 10 years but it's all worth it. Making a couple of more changes to get the 1000hp that I set out to get.
