There isn't much of a restriction, it is a pretty efficient set-up. We had a 347 cubic inch engine with a D-1SC at 16 psi of boost in a Corvette C5 with this set-up. The car was used on a road course and the set-up worked quite well, as it did not block the radiator. Bob

A T76 on a LS1 at 9 pounds will gain about 200 whp from its factory 300ish. Pounds of Boost is not the key when making power on a FI set up but more about matching the right compressor size to the right set up since a larger compressor will flow more air at lower boost over a smaller one. Just my 2 cents.
What do you think on this set up? This is what i have ls3 with a 418 stroker kit 823 heads i think they are 68cc, Wiseco Forged Piston -20cc Dish and a custom cam 236/236, .602"/.602" 115 LSA

You're welcome. New from ProCharger will be in the $1400.00 range. Guys will sometimes swap them out for a front mount when they start boosting past 14 psi, and a lot of times you can buy the complete assembly for $400 to $500 used. I see them on here is the used section every now and then. Bob

'trust' ran twin coolers and a d1sc with a 396 making 808rwhp. I dont think they will hold you back. Not many people have reached numbers this high and it was through a stalled auto. just my .02

Depends on your IATs. I would get some logs done and see what your temps are doing before you say no to meth.

Local dragstrips usually sell 100% methanol and it is normally a lot less money as they get it in 55 gal barrels. For forced induction I recommend using 100% methanol, as a water mixture tends to put the flame out. Bob
