Just realized you'd have to be quick cause you'd be doing this after you stage.

 

Yeah hydroboost would be easier and quicker but this works too just takes some practice. I did it my first time last weekend and my reaction time was 10 seconds

i have hydro boost. when i went to 2wd for a few months i could still brake stall to 7 or more psi. but both times i did i broke the left rear axle. so i went back AWD and can still stall to 7 or so psi. launches like that are crazy. i vote hydroboost but i'm bias. oh, and mine is a very very tight 3200 stall. it will only stall to 25-2800 with out boost. once the boost pushes in it goes to a solid 3200.

 

wtf is hydroboost never heard of it.. i have the same problem at track.. huge top end power but 1.75 60' is about good as i can get when i should be getting low 1.6's

 

I have a low mile hydrobooster and pump for sale! It should be in the classifies or PM and I'll post pics.

 

Hydoboost power brakes but uses your power steering to be the helper,. instead of a vaccum source. Normally 3/4 trucks have this. The bad thing is if the engine dies, there is no 1 or 2 pushes before the pedal gets hard.


Has anyone every installed a check valve in the line.

 

With the sts last year and my hyrdoboost swap I was able to brake boost 10# on the street with street tires and it would hold.

 

That is BADAZZ

 

I can build 6psi on footbrake with 91mm using the rev in neutral method but problem is traction. Are you guys hooking these 7-10 psi launches.
