I called PC and went over all of this when I bought my setup.

I will say this, get the Stage 2 intercooler at the minimum. The Race I/C would be a great option, but it requires you to remove the crash bar behind the bumper to get it to fit.

Personally I would opt for the 2" surge valve option and get a Tial 2" Q series surge valve. Either way what ever you do, DO NOT GET THE STANDARD 1.5" PC PROFLOW VALVE...!!!

That thing is junk.

The only other must do mods I would suggest is to go ahead and get the LT4 HPFP, LT4 injectors and replace the orifice fuel line with the non-orifice fuel line and get the LT4 fuel lines.

I would hold of on buying any form of CAI or ported throttle body until you make the decision of why supercharger you are wanting. If you go the PC route, the CAI will be worthless as they dont use them and the ported TB would help on a blow thru Centri blowed. If you go with a PD like Whipple or such then the CAI and ported TB will swap over to them.

Congrats and have fun.

I agree except I would always choose the P1x over the P1sc. This is what Procharger says"Both the P-1X and D-1X superchargers fit into the same brackets as P-1SC-1 systems and will be an optional upgrade for those who want increased performance on otherwise stock, modern V8 engines–to the tune of 10-15 more flywheel horsepower at the same pulley size (with stock motors running standard boost levels)!"

I can tell you right now, that with the same pulley size a D1X will absolutely DESTROY a P1SC at ANY RPM.... I had to put a HUGE pulley on my D1X just so the engine would not blow up. Even with the HUGE pulley (same 7 PSI of boost at fuel cut) boost ramp up time was only slightly affected. This is a belt drive turbo (basically) so there is no more lag because of the bigger volute or for the D1X the bigger compressor wheel. That said I think t(IMO) he P1X is the better choice, but if it is cheap enough would agree the P1SC is more than enough... spend money on headers.

I completely agree that a P1X vs a D1X what you posted based on a max boost of 7 PSI, the P1X is by far the better choice just price alone.

I will note that it is not part of this tread that a proper BOV system used as a wastegate could have a D1X with a 3.75 pulley making 7 PSI of boost at say 2500 engine RPM.....






I'm interested in the orifice fuel line? When I did my low side, I asked the dealer if the LT4 was the same from the low pump to the hard-line and he said that it was. I know the flex line just before the high side pump is visually different but never bothered to compare. So please explain?

I had no idea the standard intercooler removed the crash beam
