That is what i was thinking. Drive a 3.5psi procharged 496 HO responsibly with some occasional bursts of high speed followed by decent cruising rpms and you'll be alright. If it was grenading all over the place than noone would carry the line and there would be class action lawsuits. I am still considering my options though, supercharging versus new engine...damn all i need is alot of money!

i like mine so far (496ho/whipple),but i dont have enough hours on it to draw any conclusion....the engine has eagle rods and .030'' wiseco blower pistons,so this might save my azzz in the long run

You do know that the GM LSA engine has hyperutetic pistons right? So the new Camaro ZL1, Caddy CTSV and many marine applications in ski-boats and air boats have this same motor in it.

Hyperutetic is not a problem if you maintain decent cylinder pressures. What kills them is over pressure from detonation and high temps.

There have been many, many, many PC failures on 496's. We've done A LOT of PCM's for these. There "key" is to tell you to start at 40psi on there FMU and adjust after reading the spark plugs. So if you fail, you didn't read the plugs right! LOL They would be better off adding $200 to each kit and giving customers some wide band O2 gauge and bung and say this is part of the install, adjust until its 11.5:1 @ WOT. That would be better then giving people 20psi range of fuel psi.

Running small injectors, stock pump with an FMU is a receipe for a disaster. You can't even properly match fuel psi rising rate with injector flow. The stock pumps nearly stall at 75psi yet you need nearly 80psi to make them have enough flow. Get into colder conditions, now your maxxed out on injector. Running injectors at 100% all the time means you have almost no control, and thats exactly what they are doing. Do you know how much more fuel you need when the air temp is 60deg F vs 100deg F? Factory PCM has the compensation, but when the injectors are 100% open, doesn't really matter what the PCM says to do at that point!! Can't go to 100%. Not only that, the PCM555 goes bonkers when injectors go 100% and the motor goes very lean.

Why do people ask questions like this and then refuse to take the advice that the PRO"S give them ???? You are getting advice from some of the best in the business yet you will not listen . So my advise to you is go buy a pro charger bolt it on blow all your sh!t to hell then come back and tell use how you made out .

Maybe because alot of "pros" are just salesmen trying to sell you something you really do not need?

Put the pro-charger on and give it he11. Don't listen to anyone who tells you not to do it. Those self-proclaimed pros who've had failures and who have lots of experience playing with that engine really know nothing. Buy the PC.

We need something more fun to read than this thread..

Like I said in an earlier post... I did put one on & ran it for 5 yrs & 200 hours WITHOUT ANY PROBLEMS....and the new owner is still running it.....

Good Knowledable Advice?:
