Is it possible to supercharge and turbocharge an engine? what about NOS??
all this with 383 TPI. Maybe on an LT1.
Thanx for your help.

JeffT

anything is poss. if you have enough $$$. However, one question comes to mind--why???

GOFASTER

Why? Simple man, POWER. I will be re-building my 350 soon. stroke it out to a 383 forgged everything, dual stage 225 shot NOS, and if money allows twin turbos or vortech.

Pure power, can you say 10's......... he he

that would be the hardest motor ever to tune. pick one power adder, all easy to put you in the 10's or lower. plus nitrous works well with superchargers as an intercooler so to speak

JeffT

You can go 10's with any ONE of the power adders you mentioned. No reason to combine all of them unless you just have a bunch of extra $$$ around or you really want to be unique. So, again, I ask why?

I have run both a supercharger (6 psig) and nitrous (50-hp shot) concurrently. My signature shows the results.

With just the supercharger, I use water injection and keep my total timing at 38 degrees. I would have to retard the timing without H2O. With nitrous in conjunction with the blower, I set my total timing to 35 degrees. I do not use H2O with nitrous (not necessary).

Ryan,
what trany do u have? If its a t-5 all that power your planing to put to it will shatter it like a grenade. I broke a t-5 with a stock GMPP 350. If your gonna spend all this money on nitrous, super charger, and turbo's y dont u just buy one and spent the other 6 grand on a new motor and rear?
I mean no offence but thats just my $00.02
later

Oh yeah, how about a 400sm with 18* heads, two large turbos, and DFI? Also, planned on a little juice instead of the brake. But could use both, you never know.
-Dan when did you decide on nitrous too?

Give me 2.5 years and i will be done and looking for high 8's.
