Drivetrain Weak links, High HP failures
 

What are you high HP (400+) guys breaking on the Rx8? I see plenty of 600+hp Rx7's doing insane launches on slicks with them and they seem to be holding up well (may be heavily modded idk). I am just trying to see whats going to be the main issue...transmission, clutch, axles, or the differential.

The transmission is made of glass...the syncros suck...

Mainly...

ouch, thats worse case snenario really. I wonder if the AT is any stronger?

if there were 400+ hp rx8s, we'd like to tell you

Ive seen a few....

on Renesis ? or its already on 13B-REW

show me a "few" with Renesis. I have yet to see one, we're getting there tho.

Nah, I dont recall any with the renesis, I am sure there are some real close though. I have seen a few claims of 400+ but thats about it on the renesis.

I think the first thing that "snap" is the rear axle or something.

CRH on this forum sells an "upgraded" one thats suppose to be able to handle 800+ hp. but of course no one can get close to that (on Renesis yet), couple of PR guys got some 20B in their rx-8, forgot they're pushing it tho (hp wise)

no 400+ rx8 have been seen yet..

as to the auto trans ? if you have to ask, you need to read a bit more..

i will give you a hint the auto only revs to 7500 rpm.

i don't think those 600hp rx-7 run stock tranny. One tends to forget that lots of internals need to be changed to accomodate such hp. Unless you have a Veyron.

No...however seek ye mazsport for their transmission...or Charles Hill (Black Halo) here on the forum...

They are who you need...

I wasnt planning on swapping a 400+hp engine and 6sp for a stock renesis 4port and auto. Sometimes automatics will handle more HP than the manual in the same car, the manuals take a beating where the automatics dont.

Thanks for the heads up on the axles, I will check into those. Thanks for the input.

as twinkie said the mazsport trans is the way to go..

Sounds great man.

i like nachos!
