Wheel broke on c4 vette, clutch blew up going into 2nd gear on my third run. Red lights were to see how fast the car could go

 

This is what I was telling you guys. Launching on big Hoosiers kills S2000 diffs when the clutch is upgraded from OEM. Went through two diffs in one season (one was Comptech capped). Then went for the R200 housing (which isn't BSP legal). The pinion gear is this tiny little thing and teeth just shear off it.

This is what it looks like when that happens:

 

Awesome driving!

 

That sucks. What clutch did you have in there. After we grenaded a comp clutch we want back to oem

My pinion was fine. My diff is what granaded.

 

original osgiken?

 

Did you open the case yet? Pics? Usually that's when the bearing caps flex. Telling you that when the bearing caps don't flex, the pinion is the next thing to break. I've never seen the actual diff unit break on its own without something else being the root cause (like flexing bearing caps).

EDIT: just saw the post about the OS Giken... interested to see if it was a first gen Giken. I don't know how many are left unbroken.

 

"BSP, the class where the winner is the guy that gets to finish all his runs"

 

Yea original OSGiken. I can't see what's broken. It's something inside the diff.



Pinion looks good though



..although I don't know wtf is up with those scratches or cracks on the cover

 

Correct me if i am wrong. But there was two batches of the first gen Giken, The first batch has not had failures, but the second batch, well i think you may have had the last working one from the second batch. And then the second generation has held up nicely?
Me, and colin, and collett still have working first gens.
Agree on the keeping stock clutch, this experiment has been a great big fail
