That's awesome.... Have you done anything to the motor internally, or had any port work done? What are your other modifications?

my power goal is 150 rwhp j/k well i talked to a few ppl about the turbo the trip on the cold side is a T69.blabla so i just say its a T70 i have heard diff hp from diff ppl my fuel system can only do about 450 safe right now and the turbo can do up 34psi

so i guess my goal will be 375 ta 450 plus i have direct port nitrous with a stand alone fuel system if i need more hp woot got to love the street car

Leave the exterior just like it is........a perfect sleeper. 400 should be easy...

ALSO!!! How much hood clearance you have for carb hat? Try putting a 1/2 in 4150 style perimeter plate and shoot some methanol in there! The engine will run cooler, and more importantly boost 92 octane to 116 octane which allows for more boost! Recipe for power; im addicted.

methanol will allow me to run more boost safter. but it will not bump my octane up that high seeing as methanol by its self is only 113. if i did a 50/50 mix it would make 102 octane.

but i have a stand alone methanol fuel system on my car its for the nitrous. next thing i add will me water meth but that wont be till i get this running perfect at 15 psi.. then with water meth im going to be shooting for 23psi

(fuel a x gal) + (fuel b x gal) / total gal = octane

in your case (91 x 7) + (113 x 7) / 14 = 102 octane


did you know electric superchargers also give you 50hp?

Great, a comedian. Also note it says 116 octane "quality" I dont doubt the math, but I have used Snow's equipment a few times before and thats always the MFR's claim.....Mysterious Also supposedly, According to Snow, (god bless E-Mail) the rating they acheived in that advertisement was based on the amount of timing and boost the water+methanol injection allowed, close as hell to c16 race fuel. So, 116 octane is the level of compatability, not an actual octane rating.

My bad, but they should prolly come out and say that.

i was not in anyway saying water meth dosent work. but its not the same as octane.. it cools the air/fuel mix so it can take more boost 22+ psi on pump gas but if its used with race gas 116 then it will allow youto run more boost if the motor can handle it.

i didint meant to come off like a dick i was just stating that it would not change the octane that much. i also said i was going to be running water meth. caz like you i also know it works to be able to run higher boost with out having to spend money on race gas
