Lol, I was informed that if you wanted to go above a proper 500bhp atw you should rebuild with full steel internals or if you like your tuner that much I am sure he will re build and re build again and again, they just love taking money off us

Yeah, but how long did it last???? My Steel eng is good for 1000bhp, but I use it well within its safety envelope at 720atf and 600atw.

So does that mean it only lasted for 2 years ?

I have had mine for 11 (eng only 4 years old with about 2000 miles a year)

1400hp/10,000rpm on a stock 20 year old RB30 crank and block for 2 years of abuse, still in the same motor, in a different car, still running fine.

There is nothing at all wrong with a properly prepared stock crank even for 7 and 8 second cars, its been proven more than once and its proven reliable.
