Hey, I've been searching the forums and everywhere else and can't seem to get a definitive answer to how much power the motor take before you need to forge internals and build the motor?

 

I tried to find this when i when i had my g35. So heres what i know. first gen 400rwhp. second gen was 450rwhp. Everything i found about this motor pointed to 600rwhp with good tune but now they are pushing past that.

 

700hp. Shoot for the moon!

 

Completely subjective. It depends on how you are driving it. It's not how much HP the engine can produce, but how and how often you are using that HP to the maximum. There's no set number. Stress to an engine is cumulative over time. One guy might run a 650 HP setup on a stock engine for quite some time. Another guy might damage it right off the bat with 450 HP. There are a lot of factors that go into that.

 

+1 to BB. You could put down 600+ whp on a dyno and then cruise around in your car and shift at 3k rpm and your engine will last forever. You could also go to every track day in your area with 450whp and find yourself rebuilding your engine very soon.

 

I thought the VHR motor already has forged internals?

 

From what I understand, and this is things I have seen on the internet in the past so by no means I have I confirmed it, They say the cam and crank are forged but the pistons are not.


Great saying from a comercial......
"It was on the internet so it must be true" "Where did you hear that?" "On the internet"

 

Im a French model to!!!!!!!

 

the crank is forged and I read that the connecting rods are beefy and strong but don't know if they are forged. The pistons are not forged definitely know that.

 

Although I have an auto and it gives lower than actual readings due to the torque converter, my last dyno when I did that was 590whp with stock internals. At the track it bent four rods USING this HP.

There's a fellow with a single turbo who achieved 647whp on a stock block. The builder allowed he's now on engine number two due to a failure of some form...

If you plan on exceeding 550whp, I'd subject that's the point of no return on longetivity.
