RE: Offical nitro tc3 thread
That is a very good motor puts out hella power but it is only going to beat stock cars yet you will beat them by a few feet now if you go against a modded car they will beat you by a few feet but even so it is a very good motor I still have mine even after I bought my t.z. AND IT IS A BEAST. but I drag race and run the same gearing as flynvy5 but there is a mistake in his numbers if he runs that gearing then I am sure he is on the brink of stripping gears your spur difference is suppose to be the same as your pinion difference so in that respect he should have a six tooth diff on the pinion now that could be minus one on the 1rst or second but hey I could be wrong but I always keep them the same.
hope this helps
