This is a true dog box, with dog engagement and straight cut gears.

Yup. That's what I picture when someone talks about a "dogbox" tranny. Strong straight cut dogs, not helical cut which puts some side loading on the gears.

What you see there is straight cut gears, which puts all the force threw the shafts, which if they are designed to handle it is fine. But the dsm dog box still breaks, it is not the end all for the MT dsm.

And the Helical cut gears puts some power to the shafts and some power to the bearings, its more of an even trade.

I only have 473 torques for 720 awhp. And we made the car as light as possible, I guess I need to get carbon fiber panels, and start making suspension and sub frames from aluminum.

Has anyone looked into running Evo X gears? I have to assume they are very similar. From everything I have read they are simply beefier than previous generations. So far no one on X's has really ran into problems, even the 800whp+ guys.

I doubt it will work but figured I would ask.

I am sure he had to go threw it every now and then to fix/replace stuff, but right now that is not in my budget.

There are lots of guys making a lot more TQ keeping their stuff together, you should give them a shout a lot of them seem pretty helpful.

a car setup for mile runs makes 1098/698 and he just made some passes last week with no issues.

I hope you get this figured out soon, keep up the hard work.
