Then you’ll need the LT4 system.

Exactly why I said to get the LT4 fuel system. Most stretch the stock fuel system so it's a touch on the lean side even at 7psi. Then when it gets cooler out you make more boost and bam out of fuel.
There is a active thread in the forced induction section right now with good information. Cjperformance is the OP.

The LT4 fueling (HPFP and injectors) are money well spent. I think I spent maybe $1150ish at the time. They are not necessary on a P1SC or P1X if you stay below 7 psi and maybe 580HP. Cam not necessary. Had mine at 545 HP on stock fueling before turning it up to 630 with LT4 and E.

LT4 fuel system is a good idea because not every car taps out at the same spot. Base supercharger kits are sold as being ok for a stock LT1, but that is not always the case in other words. Cjperformance for example recently did a Procharger with the base pulley, and his was losing low side fuel pressure, while his high side was maxed out. My SS with a base pulley supercharger was losing high side fuel pressure and the injector pulse width was too much. I had pre-emptively upgraded to the ZL1 in-tank pump, so I don't know if my stock low side pump was also weak. CJ and I only knew about it because we had bought HPT, so many guys are unaware of how close to the line, or even over, they are on the fuel system, because they are not datalogging. This means that a lot of the guys who've said the LT1 fuel system was adequate for the supercharger, don't actually know whether it was or not.

One thing to keep in mind. A LT1 with about 7psi makes similar power to a stock LT4 which makes 9-10 psi. The higher compression of the LT1 allows it to make similar power at less boost. The LT4 comes from the factory with a better fuel system. Ideally you will need to run the LT1 a touch richer for cooling on pump 93 due to the increased compression which further increases fuel demand. So that means a 7psi setup really needs the LT4 fuel system hence why I always suggest it as a minimum.

Agreed. I ran mine around for about a year before doing LT4 but I didn't beat on it relentlessly.

Same here…about 10 months. With Prochargers tune and LT1 fuel, it put down 545rwhp. With custom tune and LT4 fuel, it jumped to 589 (same boost: 7lbs).

Very similar as mine. Got 553whp on stock fuel. Saw you are at 707whp now, what is done to reach that? 700s are my goal this year just ordered stage 1 cam 38% fuel, LT4 pump and injectors, pistons, rods and E85. Hoping for high 600s at least.
