I know what most of you will say. Dont push the stock bottom end with our glass like pistons. But im curious if anyone is pushing 600 or slightly over with a great tune. My car is breathing great as it is so theres not much restriction. I figure if I go pop then its 426 time anyway.

I'll be on a dyno soon with my HHP-Procharger setup. Oversized intercooler, 87 throttle body, exhaust and a killer tune from Josh. Fingers crossed!

How much boost? Nothing forged right.

7 psi and the engine internals are bone stock. Josh recommended we leave the engine alone and stay below 8 psi with a safe tune.
Now, all dynos are different so I don't know about eclipsing 600. But the number means little to me, it's the driveability I'm after. So we'll do a baseline dyno and a final which I'll post up. But key for me is that HHP will keep the car for a few days and tune her for all of the little glitches that can sometimes come up.

Im actually referring to 600RWHP or more. 7psi will keep u well below that number.

Dad just got off the mustang dyno with his rt 392 motor swap, forged pistons, stock cam, apache heads, headers, 6.1 intake, 90mm, procharger 9psi 598rwhp. Believe it would have been higher on a dyno jet.

You would be about 670 whp until the pistons burned up and blew the motor...should get a few dyno runs before tha happens though so will have a nice piece of paper showing power output...and a 4300 lb paperweight to hold it down. :icon_eek:

haha... Yeah I wouldn't crank boost to 9psi on stock internals and a cam even though yours is mild man...even running E85 and being cooler running...not likely to last long at all.

I have emailed back and fourth w/ Josh recently...HHP seems top notch... Cant wait to hear your results....

My install is scheduled for next week now so I'll post results right after. Who knows, maybe I'll be lucky for anchange and my Challenger is a factory ringer! LOL

I've always heard there are a few unicorns out there that just run strong as hell. Sure would be nice to have mine be one so we'll do the before and after dyno to confirm.

611 rwhp 2011 srt8 gwe

My car Dyno-ed at 611 RWHP. I am running Kooks Headers and High Flow Cats and a Maggie SC.

I have a stock bottom end and have had NO issues......except the fuel pump which I just upgraded otherwise plenty of power

I only have 13,000 miles on the car, 6000 of them with the SC and I drive the car hard

No issues to date, knock on wood and I hope to keep it that way.

I change my oil every 1500 miles, full synthetic Mobile 1, other than putting gas in it and changing the tires once a season. I just switched from Cooper to Nitto NT-01s and they are awesome. I have never had better launch or handling traction!

Thanks man. That's exactly what I wanted to hear. How does it do on the strip?

I had a stock bottom end and blew it all to pieces. Now I am all forged. You are on borrowed time with a stock bottom end and a supercharger. Trust me! i see'em all the time.

How much power were you pushing and what were you doing at the time it blew. What other mods did you have?

Arrington fuel pump, SRT4 injectors, 180 thermostat, bigger intercooler, Josh/HHP tune. The helical gears are almost silent and best thing for me is that the entire experience just feels like a bigger motor. Josh has done tons of Procharger setups with stock pistons. The key I'm told is in the tune. And knock on wood, to date not one of his has grenaded.

No cam or headers? The reason I ask is my buddy has a procharger with 7.5psi and isnt running that much power to the wheels
