well i am looking for a slightly smaller pulley now (i have a 4.00 right now) i am at 8 lbs of boost. (fyi i am in colorado 5200 ft elev.) i was thinking a little more boost with methanol (??) would you go 10 lbs with meth... or even 12 lbs with methanol? waht would my boost be with the 3.75? approx? when they sent me the wrong pulley (4.25) i had 6lbs, with the 4 inch i have 8lbs...would i have 10 with the 3.75 or??...is my thinking correct??..thanks guys

With the pulley I would expect you will get near 10psi. I would definately go with Meth are you speed density?

If yes I would go pressure progressive controlled Meth if MAF I would use a MAF progressive controller.

Good luck

you can also get a bigger crank pulley

At some point you will likely go to SD. If it were me I would get a Meth progressive controller based on Boost.

That way you can use it with MAF and SD. I use LaBonte there are many companies selling them now. Also you will need to lean out the tune especially with Meth

Good luck

run a 3.4" pulley and throw a restrictor plate on it to limit the boost to 10 psi. then run the meth.
