my build is an E85 357 twin turbo and i dont want to run an intercooler. How much water/alky should i run to keep things cool? is there a caculation i can do? boost will be kept in the 15-20lb range.

 

Are you looking for what meth/H2O mixture to run or actually how much of it to spray? Mixture wise, most that mix run a 50/50 mix. If your looking for how much to spray, then i think thats probably dependand on your setup. Its usually controlled by nozzle sizing, although even that will vary depending on what psi your running your pump at, weather its full on at a given boost level. I run a Snow system. The flow amount is also controlled by boost level. I'm not familiar with the Alky Control systems, but i would guess they have a similar setup. You'll know when your spraying too much cause it will just fall on its face. But just because it falls on its face doesn't always mean your spraying too much. Might just not have enough timing in it either. Tuning can be tricky, so read as much as you can and you'll need trial and error also when you get it running.

If you are already running E85 you should have plenty of octane. I would mainly focus on using 100% pure meth to cool the charge down. 15-20% of the total fuel consumed should be methanol.

 

that sounds correct, we used aprox 0.10-0.15 gallon on a 8sec run and a burnout. We used 75%meth 25%water and a hob switch that turned it on at 10-12psi..

 

im looking for the amount to run. would a single stage be enough or should i look at a two stage?

 

You mean one nozzle or two? I'd run two smaller nozzles before I ran one large one on your setup.

 

i thought there were a couple of kits that start spraying at lets say 5lbs, and then when it gets to 10lbs, sprays more.
