what's the record power output for the 4g63 on stock bottom/stock internals?

 

i think people have pushed it up to around 560awhp dynojet for short dyno testing

 

WOW. but would the motor be ok with that much power?

 

I recently put down an average of 480whp on a Mustang with a peak of 500. Also, this was on a 92 octane pump gas map that we just put down 410 whp with 22 or so psi. Drained the tank and put 110 and turned the boost up for 2 pulls and got the 480whp average on 26 to 27 pounds of boost. Don't know what it has left in it, but not really wanting to find out, so I am doing some upgrades to the bottom end before it lets go.

 

what turbo and ems setup are you running?

 

i've seen it high as 550whp on stock bottom with upgraded turbo/ FMIC.

but you know, i don't know if you count cams, cause it had cams in it.

 

I believe Al (dynoflash) has the highest stock bottom record. He did 556 before pulling the motor and building it a year ago.

 

yeah, i was just wondering what stock rods/pistons/etc could hold. cams are cool

 

True - and our fearless customer Superz make 535 on his engine and keeps driving it.

 

Thats a very strong engine.

 

Sup Al! I will be visiting you soon Actually I traded the blue Evo in a month ago and now have an MR I will soon be re-installing all of my old parts and will get flashed once again- 500+whp here we come . My BBY Evo held up amazingly well even when running 23psi daily (=425whp). I never had any issues mechanically, no headgasket problems, no bottom end problems. There is NOTHING like driving a stock ECU Evo daily, nothing beats the driveabilty.

 

Did you have stock rod bolts also?

 

can you hit 500whp stock rods/pistons on pump?

 

I upgraded the rod bolts and headbolts to ARP hardware. And no, I dont think its possible for anyone to ever hit 500whp on pump.

 

big enough turbo and anything is possible. if you can deal with your power coming on at 7k.
