Looks like a cool setup. Do you have any pics of how the hotside runs up to the turbo inlet? I have to get my stuff refabbed so a reroute might help. Pics would help best.
As for the ebrake thing, Gen 2s have another set of brake shoes for the ebrake that the Gen 1s don't, thats what FMOS was talking about.
The technique I was using worked like this.
I had a front line lock so during the burnout I would use it to hold the truck still and then put a little pressure to drag the back brakes a little. This would put some heat in these pads so they would grab a little better.
Next I would roll up to the 1st beam, stop and set the parking brake HARD. Then I would move my feet to the regular gas and brake pedals, putting light pressure on the brake and giving enough gas to get close to my stall speed (2400 RPM). Let the other guy get all the way staged at this point so you have control of when the lights come down. Put your hand on the ebrake release lever at this point. Holding light brake pressure bring the rpms up until the truck lurches forward into the 2nd beam. You will get a feel of how much brake and gas to use to get just the right amout of movement. Once you are in the 2nd beam STAND on the brake and bring the RPMs up to just below where the truck will roll forward. When the lights come down mat the gas and release the brakes and away you go.
Doing this helped my cut my 60's by a 10th or so. I really needed a higher stall for my combo. I never fiddled with the shifting and such.
