did you drive the car home?

 

go get your car up to 130 or higher with the pads that are in now. you will find a lil suprize. much better then stock but i am shore a true race pad would be better but for dd you cant go rong. i do need to get to a bigger track. it deff looks like loads of fun.

 

Dan, I was doing that yesterday...I hit 130mph on the front straight every lap. This is why I am able to make a direct comparison, because I've raced on this track several times now, but the previous times were on stock pads, and yesterday was drastically improved with the HP+'s. I was able to stay on the gas longer, then brake with much more confidence and easy coming into turn 1. It was the same on all the hard braking corners - out of 10 turns, 4 of them require threshold braking, and the pads helped in all of them.

 

I think any pad is better than the stock pads.

 

Not really.. the first 3 gears on the MR are wider, the other 3 are smaller (6th gear does not count because obviously we can't compare to the 5 gear tranny) .

Autoplus from the Philipines runs 9's on stoick 6 speed tranny and Cusco transfer case.

BIG BIG BIG difference between running WOT for 9 secs and running WOT for 20mins.

Lots more heat, lots more stress, lots more everything.

Doesn't take much to break a gear, but it takes a man to melt a gear.

So far it is proven that the stock 5spd can take the abuse of the road course much better than the stock 6sp. Even Jon@TRE's first question to me was "You sure you don't want to go to a 5spd?"

 

I'm pretty sure you'll fade the HP+'s w/ R-compounds. Sucks to hear about another 4th gear failure. Hope you get it fixed soon. I guess all those heat sinks Mitsu put on the tranny housings weren't enough.

 

Yeah ..but BIG BIG BIG difference running a car that makes 350whp and the other that makes 700whp plus..... Either way, somtime is unpredictable but it looks like there is a pattern of 4th gear failure. TTP's car also had the same failure but remenber TTP's (Scott) and Warr raced their car a lot too.

I'm going to quote my post above, this time with bolding the key parts in hopes that you actually read it this time...

This has little to do with power. It has to do with heat and the prolonged stress that makes with a car on a road course. Sure 9 secs of 750whp produces stress on the gear face but heat abuse on the road course stresses the gears from the core

 

Welcome to the club Clayton. Member #004.

 

I know what you mean Bryan. Lets wait until we see what caused the failure. I know that TTP's had a massive tranny failure because one of his gear basicly desintegrated taken a lot of debris inisde the tranny and ultimately destroying the tranny completly. Warr's failure is an isolated gear but I hope that his damage doesn't get any worst.

And mine was 4th gear as well. The box is still able to go into all gears including 4th gear fine, but 4th just sounds really broken. Obviously something isn't quiet right with the gearbox. Jon says that 4th gear basically breaks down from the heat and the tolerances change, then everything gets grumpy and something gives.

Jon told me that mitsu has know about this problem for awhile but haven't done much to fix it. I look forward to seeing what Jon finds wrong in my gearbox.

 

Thanks for the info Bryan... I hope that we can build a big database and a create a good collection of pics from MR 6 speeds failure and perhaps show the people the diffrent routes and alternative they would have when facing such issue.

Wartalon, if you need a 6-speed quickly, I've got a spare that Jon (TRE) is just finishing. PM for details.

 

CO_VR4, I will keep that in mind. I don't need it for anything other than having my car for daily driving really (other than my next SCCA auto-x on Aug 12, but I can miss that), but luckily my wife and I work for the same company on the same floor of the same building, so we can just work the same schedule and commute. I would have no qualms with using a TRE-built 6spd, but I'm first going to see what Shep has in store for me (tomorrow).

Scott, I figured it was an inevitability with as much as I've abused this thing for 20k miles - that's probably why I wasn't too upset when we figured out it was 4th gear. You can actually hear a chunk of metal bouncing around in there, which surprises me, because I figured the oil would deaden the sound. It actually sounds like rock tumbling inside a clothes dryer, which seems kinda weird.
