how much power can a stock 2003 350z tranny can hold without worry about breaking? thanks you

 

You're welcomes.

 

pretty close to 320 hp. after that it starts to grenade.

 

Ha....

Sound Performance put 1150rwhp through the stock '03 trans (008) and went 9.35 @ 158 on same trans......
They put 1248rwhp through the newer 009 trans and went in 9's a few times before oil pump let go....again

how long will it last....who knows

Tom

 

I would say to take it past 276.789345 WHP would be pushing it and you should take extreme caution.

That or install a search button and it will prob be ok

 

300 hp

 

428.611 horsepower until failure
