Procharger cam swap HP numbers? Just wondering if anyone knows how much of an increase of HP I should see from a stock cam to a TSP 224/228 .581/.588 LSA 114. This is on a stock displacement LS1 with long tubes, full exhaust, intake and 7lbs out of a P1SC. I'm also trying to figure out if I will have to change injectors, I have Bosch 42lb injectors on it now and I've read so many different things on these. I plan on putting a Walbro 255 in tank fuel pump in it. I have the little procharger piggy back fuel pump on it now.

Well all I can tell you is that i'm running Bosh 42's with a Walbro 255 and hot wire kit, and at 550 rwhp i'm doing just fine. But the difference is that i'm running a nitrous wet kit which doesn't pull off the injectors like a blower. I believe the 255 pump should be good close to 600 rwhp IIRC

OP, I don't remember exactly, but I wanna say the 42's were close to 90% max duty at the 550 rwhp mark. But remember you will be maxing the injectors more so with that blower.
Crazyelf, I was referring to the injectors and not the pump

im betting you will be able to gain 40-50 rear hp . You may have to pulley down to make some more boost . Im right at 500 and my buddy has a setup just about the same and made 560ish with a cam but then was backed off to about 500 for longevity reasons as the engine has 122k on it .
