Hello everyone i definitely feel like i made a big misstake choosing the P1SC. I have now ordered expensive FIC30s, LPE HPFP, 32% lobe cam so i think i have plenty fuel but i feel like its going to be limited now by the P1 supercharger. I think im going 3.4 pulley and i bet it gives alot of boost but i read that the D series or even better F series would keep it going cooler. What is you guys opinion? Maybe go for more E% and that will help? Will a GT35 42% cam help me alot? Very thankfull for every tip.

Keep in mind an f series will require a 10 rib pulley system AND the biggest pulley you can put on will have you at over 14 lbs. P1SC should allow you 750+ rwhp with the right combination of supporting mods. If your piston rings are not regapped for boost or you don't have forged pistons/rods installed, that p1sc is more than capable of blowing your stock bottom end.

I’m at 707rwhp with the P1 (93 octane). I too thought I made the wrong decision but I was never planning on making it to this point. I’m only at 7-8lbs of boost right now so I think it will be fine. What are your power goals?

Iirc you can send it in for a D conversion if you feel the need.

P1sc is efficient in the 7-8psi range. Above that it starts to climb above it's efficiency range. You can cheat that by spraying meth injection and it will cool the boost which will allow it to go further. Even the P1x starts to crank some heat out once above 9psi. Imo a D series supercharger is the sweet spot for most builds not using meth.

I would Contact BRC race works and get a 43% lobe from Ryne Cunningham to maximize the potential of your LPE HPFP. 32% lobe will work but you might be mixing around E60 to keep the fuel system demand in check. Nothing wrong with E60 as it's the sweet spot for Ethanol on most builds. You just have to deal with mixing the stuff which imo is not that difficult. But either way, since you spent the money on fuel system you might as well get the right cam lobe to fully utilize the systems potential.

Ok Thanks for info again! Do you think the LT4 intank and JMS booster will be able to support that much fuel?

It would depend on the percentage of ethanol you attempt to use. Pump e85 only, probably not. Blended pump 93 and e85 as King mentioned to you to make e50 or e60, yes it will support it.

That’s to bad. Maybe a dsx lowside could help? And yes i have a set of drop in pistons and rods from GPI on order, just waiting for the compstar rods to get ready which I feel like is taking forever lol. Not GPIs fault though

Goals is not really set yet. 750 ish would be great. I just got obsessed with the fueling I guess lol and I feel that i have focused to much about fueling and am forgetting that there are other important parts to the build lol

I talked to procharger last week before I ordered. He recommended going with the P1x. Little more efficient bearing setup than the P1 and D1. He said they really work good on the modern muscle cars especially with the 8 and 10 speeds. I also got the stage 2 intercooler. He highly recommend that.

Sounds great! Thanks for the info.

I currently have the P1X and stage 2... no complaints except now in the heat. The IATs really climb and the intercooler doesn't pull enough heat. If I had it to do over... I'd probably have gone with D1X... or a Maggy... but I've heard there are tradeoffs so.... ???? P1X with more effective intercooler options would be great.

Guess I’ll try it out with the P1 first and see how it performs. Yeah I read your thread and at the same time I was experiencing the same issues. It was insanely hot and humid here in Sweden the other week and it was very noticeable that it pulled timing.

I have the P1X with 3.7” and the 8.25 balancer pulley (12psi). Stage 2IC. LPE,+30, btr stage 2 cam (32%) fore in tank pump. I made 840whp on full e85. I’m planning on putting a 3.55 pulley on soon. Gonna do the D1X upgrade and race IC over winter possibly. Just sharing my experience. Good luck with your build
