lauching boost??

[dank GN]

What do u guys leave at? i have a t brake and was leaving off 8-9lbs and was only getting a 1.8 1.9 60' times. also if i drop a 10th on my 60' what does that = on the top end?

I launch at 15lbs and get 1.4x 60ft times. I also have moser 31 spline axles, broke the stock ones over time launching that hard. I believe a tenth on 60 ft is like a tenth and half on top end

I believe a tenth on 60 ft is like a tenth and half on top end

that is correct

every setup is different i suppose, ive been leaving with about 2" vaccum (brake issues) and manage 1.88-1.94 60' times

How do you launch?
A. Floor it on the transbrake, then let it rip when the boost is at 8-9psi?
B. Sit on the brake and apply just enough throttle to get 8-9psi, release the brake and floor it?
C. Pick a certain rpm to launch at which happens to be 8-9psi?

My avitar was a 9psi launch off the brake, method A

Leave as hard as your tires and drive train will take. Leaving at 12psi, the car would 60' in the mid 1.5 range.
