Which Superstock Motor? Cannot Decide

[Wrc action 0]

Simple question which superstock motor is best for this car

its my prototype volkswagen race touareg, using a TB02 chassis as a base.

Ratio just under 10:1

weight sbout 1900gram

Cannot decide if a TZ torque based motor or a BZ motor would be best, I am looking for long run times, 20+ mins and also for a decent turn of top speed tho most important is the acceleration and also a motor that runs cool. I have used TZ motors before and been impressed tho the BZ is also appealing.

Any advice greatly appreciated.

Cheers Ryck

I have ran both a superstock RZ and the BZ in my re-re Hotshot. I found that the BZ gave marginally better run times, the motor ran cooler and so did my batteries. Accleration was much better than the RZ (indeed, for some reason I had a problem going in reverse when using the RZ, something I put down to gearing...). Top speed, well the RZ was faster, but there really wasn't much in it. With the BZ you're supposed to use it within a 9:1 to 11:1 gear ratio.

Hope that helps
