how much boost is that on? That was an awesome run, like i said in that other thread, its been fun watching this truck keep getting faster.

 

Its almost dropped a full 3 seconds and +16 mph since i started watching it.

 

12 psi...no intercooler so 12 deg timing up top....we wanna keep it safe.

 

That truck launched hard out of the hole.. Where did he buy the 2 step from??

 

is he still running the gt67? What about meth, i cant remember if he was using that last time or not?

 

It is a Harlan 2-step.

 

what does a 2-step do?

 

You set it to an rpm. On this run 2900. You stand on the brake and floor the gas. Once rpms hit 2900 it kills the spark to one bank of cylinders and holds the motor at 2900. When you let off the brake all cylinders hit and all hell brakes loose.

 

cool, does the harlan go in 100 rmp increments.
