Procharged LT1

Dennis 2ss · 01-15-2022, 11:03 AM

Hey guys i currently have a Procharged Camaro SS. I already have LT4 in tank and JMS booster and 2 inch kooks headers. Dynoed 553whp 492 ft lb with that. Now i want more and ordered this...

GPI pistons n rods drop in package
WeaponX stage 1 Centri cam package 38% fuel lobe
LT4 Pump and injectors
Flexfuel

Now my question is where is the limit here fueling wise? Is it the injectors still?
Im considering upping my order with FIC 30% injectors instead. Goal would be 700whp but 650 isn't bad either for me.
Oh and the procharger is a P1SC. Thankful for any tip.

Looks like your pretty much on track and no what to upgrade next.

LT4 in the tank - check
Did you do LT4 high side pump?
LT4 injectors is a must.
You did the fuel line booster - check

I would consider doing the heads to complete the set up.

Very close to my set up…..I had the heads done tho. I almost went with the FIC 30s but ended up not.

High side LT4 is ordered and LT4 injectors. I will talk to my tuner about the heads. Might as well do them now when its opened up. Just wonder since im going E85 mix if the LT4 injectors are good enough or i should just have ordered FICs 30% extra Injectors?

Yeah i could save the money and skip the FICs and just do the heads instead

I’m at 7-8lbs of boost with the P1SC as well. What are the cam specs you’re looking at?

If you have the cash get the better injectors that’s my thought but ask your tuner for sure. Let me know what he thinks, what’s the price for 8 of them?

$3200 so they are pricey plus i'm in Sweden so 32% extra with taxes bullsh.

From my understanding, LT4 set up (hpfp, injectors, & intank pump) is good to high 600'rwhp on an ethanol blend. Adding a cam to that, I think that you can almost max out that p1sc.

For comparison purposes, my cam specs are:
Intake: 228 @ .050
Exhaust: 240 @ .050
Intake lift: .646”
Exhaust lift: .646”
Lobe separation: 116

Last I checked Extreme XDI + 30's were 2500 when I last looked. I would do them for E. Best of luck.
