I have read that the 3.5" ICs are more than enough with 7 psi and the 4.5" IC are only required over 500 HP. Has anyone had issues with theirs, I would think that if there was that they would be standard with the kit as they are with the D1SC? Where I am we do have a high humidex during the summer, as I am going to order a complete kit it seemed like a good upgrade but I am staying with the P1SC-1 and 7 psi so I'm wondering if is worth it? Thanks, Les.

On a 85 deg day I will see a 30 deg increase in intake air temps on a 1/4 mile pass. That is a P1SC-1 at 8 lbs. Gonna try some meth hopefully this summer.

11 psi no problem on my 3.5's and did not see much gain going to fmic

really ? im on the 3.5" and was wondering about this . Id like to get a set of 4.5" ics but if you get the 3.5 i would do meth along with it .

I called Procharger, they said the difference is only at higher boost levels, about 10 degrees. Supposed to pick up .5 psi though?

But when we do the f1-c it is game on for a street car

Sorry, not getting your point?

Think of an intercooler as a restriction to flow. It's a double edged sword. It's got to be big enough to cool sufficiently, but if it's not big enough it becomes a restriction just like exhaust that's too small. So on a stock car, shorty headers might be enough, but for a larger cube motor with heads and cam, they are a restriction. Same thing with the intercooler. If you're only pushing 6-7psi from a P1SC, 3.5" intercoolers are enough, but start pushing more airflow, and the intercoolers won't flow enough air or cool the air enough.

Right on and that's my point, I am not planning on going over the kit design, I've been down that road and it never ends! What I am really trying to find out is, is it worth it at that boost level to go with the larger intercoolers? If they are good for up to 500hp I am protected, but if they are marginal then its a consern? Also, if there is less pressure drop and I pick up some boost, will the tune still be "on".

It all depends, who did the tune? The beauty with a procharger or any centri blower is the boost is linear. So if they tuned it for 7psi of boost, it is just as easy to extend the tune out further since it is somewhat linear. Granted, it's not perfectly linear, but a little extra boost shouldn't hurt your tune.

Its the tune that comes with the kit. I'm getting ready to order it, staying with the P1SC-1, not planning on going over design. Just would like to know if anyone has had issues with the 3.5s or if at that boost levels would the 4.5s make a difference?

FYI, spring for a custom tune, it's safer, and will perform better. There's no way they can adequitly tune every car to perform well with a generic box tune.

Well, Procharger and the dealer both say for a stock LS1 this is a 50 State Carb legal Dyno tune, supposed to be turnkey, for 7 GRAND it should be?

not trying to hijack your thread, just wanted to meantion that I'm selling my FULL D1SC kit and I upgraded to 4.5" intercoolers, went to 60 pound injectors and got the stealth 340 fuel pump. It only has 110 miles on the kit nothing wrong with it what so ever, as soon as it got put on and did some pulls on the street the 60e was toast.lol Also as to the questions to 3.5-4.5" intercoolers the others are correct as to the 3.5" will be restrictive to a certain point so the 4.5" is better in the long run that way it gives you some room to grow if you want to go over that 500hp mark you want.

absolutely 100% agree!

2002 T/A

OK, but I have no intention of going past the 7 psi kit for various reasons or I would go 8 rib, D1SC and 4.5", 60lb injectors from the start. Just want to stay with the kit, I may get it on the Dyno at some point. Back to the 3.5"s, are they more than enough under 500hp, do the 4.5" have less pressure drop at 7 psi? Thanks again

Yeah for up to that mark if all you want is 500 with no plans of going farther then your fine with the p1sc you won't have an issue. But I know for my off of 8 pounds through my 4l80e mine made 535rear wheel HP and I honestly got used to the power way faster than I expected wanting me wanting way more. It is very linear power so you get more boost the higher RPM's you go but I think you to would be wanting more.lol it took me a day and I wanted a minimum of 700,it's funny sometimes when you have a set goal then you get there and plans change quick lol

I know what your saying but then more is never enough. Then you are putting more fuel in the tank, upgrading the already weak diff, frame connectors and so on! Then you can't even use it on the street and lose it all when you sell it! I am willing to lose $10 grand to do this and $500 a season on back tires to have fun. Learning to control my obsessions with age and manage the loss when I upgrade to something better! Lol for sure.

just a heads up but if you want a procharger no way is the base system 10 grand, id call around to some sponsers and see if you can customize the kit to what exactly you want, you might get a better deal. Also subframe connectors are cheap and a great insurance for you. As far as the stock 10 bolt, those are always on borrowed time, 9" and your done problem solved. If you want to drive it and do some highway pulls your not going to run into overheating issues or anything like that, 7 pounds is it then your golden nothing to worry about don't worry about the whole heat thing....nothing to worry about, put the kit on, rip and go...well of course tune but you get where I'm going.lol
