One question, and yes I have search but found different opinions about this. Should the meth start spraying while Im making boost on the tree? I had a problem before, while making the burnout and the meth started spraying it would turn off the truck, the meth was set at 4psi, after I moved it to 6psi and it wouln't spray, problem solve. But what if I want to make 8psi on the tree to launch?

 

it depends if you have a on/off system or a progressive system. mine works off of injector duty cycle so i can build all the boost i want on the tree. but if you have a straight up on/off then it might give too much juice all at once. i put up a thread about this before but like you said there are alot of opinions on the subject. i have a log from when the wife went last time to the track and she stalled to almost 13psi on the line while spraying meth/water.

 

put a window switch in line with it. This way you get both, boost online without drowning out your spark and meth on the run to give you your octane boost.

 

I have the snow performance boost cooler, which activates by boost, start boost which sprays less then full which sprays more, I had set the first stage on 6psi and the second at 10psi. I was told to put a window switch, which would you guys recommend?

Thanks for the help.

 

Mine starts to come in @10PSI, and is full by 12. If Im only running 10PSI I have it all come in @9, and I run the small single nozzle.

 

You cold set it up just like a nitrous system to only come on at full throttle. Combine that with dialing in the boost level and you shouldn't have a problem.

 

Well Im only running 10psi right now so Im gonna set both to start at 9. I want to run 15psi then I'll set one at 12 and the second on 15. hope it works.

Im going to install a nitrous system this week and now I don't know if to use both, meth and nitrous, I want to use the nitrous just for the 60's

 

What size meth nozzles are you running?

 

I really don't know, I would need to ask Allen, but I'm going to try it like yours this week and lets hope it works.

 

I just install the 2 step, it works goods, I can built boost at 3300 rpm but without the 2 step I need to rev the truck to over 4000rpm to make boost, the weird think is that if I keep pressing the gas the rpms will go up to 5000rpm which I don't know if thats right???
