I've got an Edge Comp, K&N intake, 4in Exhaust, Holley Blue pusher, Plenty of Clutch. What next to get to 500 HP? Is it possible with Edge Nozzles?

 

you need a turbo and injectors. a 62 or 64mm charger and some 150hp injectors should get close to 500hp. do a 64 and some 200hp injectors and you will be over 500.

 

Don't forget the heads studs.

 

With a drag comp and 150’s and stock HX-35
Aggiehorsepower made 428hp and around 930 on level 3. 4 & 5 he lost power not enough air.

 

What were the EGTs like?

 

Yeah, I'd say you need at least 150 hp injectors, but the HX is never gonna get you there. Dieselfan gave some good advice. My goal is a larger single, and 150-220 hp sticks on top of what I have, should be an easy 500.

 

Would everyone say that 450 HP is the max with a stock head gasket? It seems that 400 HP is the max with a stock turbo if no NO2 is used.

 

Not an apples to apples but Rick is over 500 on a stock HG, and I think Brian broke 500 as well. Not sure what GB did on his last dyno with the stock HG...

 

Im over 400 with the stock turbo. But I should have the head back next thursday, with the full treatment. Im hoping for abit more.

 

I'm at the power you see now in my sig with a stock headgasket. I'm putting studs in this weekend though since I'm running water/meth now and I plan on upping the boost as well. The numbers in my sig were before water/meth and only at 40psi of boost. I think that with 50psi of boost and some water/meth (low concentration of meth) and some more timing I could break 500.
