Bill, I am new to this site but wish I joined about 12 years ago when I started to build my car.I have had lots of hot rods with lots of HP before and if I realised that helical cut gear trans axels suck for having to much torque I might not of built this type of car. My opinion ,after fighting to keep my transaxel togather for years ,is they cannot with stand close to 600 ft lbs of torque on a road race track. I'm sure it,s my fault for having that much torque ,but there is nothing better than having your hands just about ripped off the steering wheel coming on to a streight away.I to have an RBT. And have had many delays from them. He is a small co. and a nice guy but probly has to much work and not enough employees.I have had my trans rebuilt at pantera performance in CO. and RBT. Pantera performance was much faster. My trans axel lasted two years without problems on the race track. Now it starts leaking oil out the front seal after three days of track time. I beleive that the case is worn out and causes the input shaft to whip and wearout the pilot bushing in the crank
I have dail indicated the bell housing numerous times and it is within .003. I am thinking about dumping it for something different and stronger ? If its not to late you should concider somthing different than a zf if you are going to have lots of HP and torque. Just my opinion.
