I guess this is directed at the FI guys. When have people started to experience failure or have observed their tranny, diff, rear axle feeling overwhelmed.

Want to know because it would be interesting to see at what power level a whole new investment is required.

Thanks.

 

About 200 crank hp, or ~155 rwhp.

 

Are they really that bad? If so, this really isn't the ideal platform for super/turbocharging then.

 

I think 200 RWHP. The Comptech diff. has huge billet U clamps holding the gears in it. Work's good to keep the gears from getting shuved out the back under power.

STOCK DRIVE SHAFTS-

 

So in other words, no more than stock power then. Why was it that Supras, Zs, and Rx-7s were able to handle such big power boosts? Or am I mistaken?

 

I think a lot depends on your driving style. If you are dropping the clutch at 7k RPM and are speed shifting, you are stressing the drivetrain much more. The reason the S2K has a soft clutch is to let the clutch absorb that initial shock and not your transmission, gears, etc. Upgrade to a quick engaging clutch and you increase the stress exponentially on the rest of the drive train.

 

so
that means i shouldn't be upgrading the clutch until i upgrade the rest of the drivetrain cause we want the clutch to be the wear our item?

 

Thats my opinion. Think of the clutch as a safety fuse for your drivetrain. Of course if you are careful, you won't need that margin. I think the Honda engineers did it right!

 

Reverend, et al,

Any tips for keeping the stock rear end alive (besides not raising the HP or dumping the clutch at high RPMs)?

 

Umm... prayer? I couldn't have driven much easier on my second rear end and it still was messed up (made noises while turning). When I rebuilt the rear end, I found nothing broken or worn out. It was just a defective diff. Lawsuit is pending... and their lawyers are playing hardball with us.
