Hey guys, i'm trying to figure out how much power the 04 G35's rear end can take.

I'm about to build my motor, and my turbo setup is already over 500hp to the crank. Once I build my block, i'm going to be pushing ~720ish crank. At close to 550whp, I know the chassy will start to twist. I have a 4 point roll cage, and chassy supports being put in for that. I just need to know whats safe for the axle and differential.

Any of you heard how much they can handle? Or have you had problems with it yourself?

Thanks in advance

This is the picture thread of my car, if any of you are wondering.

 

intresting question
also want to know the stock limit

 

Talking about the block? Because I know that already. haha

 

and now ???
sorry

 

Stock block is good for ~390whp, for safe driving (on 93octane)

Mix a little 104 octane and you can bring it up closer to 440whp. That much will eventually take it's toll on your motor though, block isn't built for that much pressure. If you run ~400 constantly, you'll have a few issues down the road.

 

The rear axles can't take much. I can't give you an exact number but it is common for FI'd guys to snap axles at the drag strip. Some of the 350z guys even went as far as to buy extra axles in advance because of this. There is a shop however ( I just can't remember the name right now ) that sells aftermarket axles to handle the extra power.
