Blown 502 Mag efi Makes 1000 HP?
If I were to install new injectors, port the intake and plenum area and use a fast or haltech stand alone EFI controller can I make 1000 HP? The questions are : Is the intake too restrictive? I question this because of only spinning about 6000 rpm. Does anyone have any experience using this manifold and throttle body with higher boost ( 7-12 Psi)? Thanks Greg

Im talking about the std 502 Mag efi unit not the 454 mpi or the hp500 efi. The area of the throttle body is about the same as a 950 holley, and I have all of the stuff fuel rail sensors etc. I would just like to up the boost to 10-12 lbs. Greg

Hey Greg, you tryin to make that Eagle fly.
I don't know if I would trust the stock crank or rods for that much HP. Are yours after market? I think you have forged crank and pistons since you are already putting out around 800HP, right.
Sounds like a fun project.

I've run 11-12 lbs boost with this engine and made 744HP with all stock components. Just need a big intercooler and blower. With all the right parts-cam, heads, etc., could see 8-900HP. 1000HP would be tough but could get very close with a 540 and all the right parts and 10-12lbs boost.

With race gas and enough boost, dang near anything can make 1000hp. Just a matter of whether it will hold together or not.
Kid down the road had a 348 Ford motor showing 1000 on a dyno. Had VP race fuel and close to 30 pounds of boost at 7000rpm. I think it stretched every head bolt and main cap bolt in it. They had planned to drop it in the car right after the pull, but they have gone back inside it for mysterious reasons...

I did a 454 Mag with Brodix heads. The intake was extrude honed at AZM. Running a 2000 CFM throttle body and 6 PSI boost it made 789 HP @ 5500 RPM. I don't think the stock bottom end would last for very long if you ran it hard though. This engine has been together 2 years, but spends 99% of it's life below 4000 RPM.
