hello rob, i'd race if i could drive. i seem to be able to build a nice truck here and there but i'm really just a basher. i'm wondering if the storm center diff is really going to hold up to the punishment of the .26 with the mutant chassis setup. it honestly seems a bit flimsey in comparison to the rest of it. everything else is steel except for the front/rear diff housings that are stock t maxx. don't get me wrong, i'm not knocking the storm. yes i've seen the the more expensive torsen diffs but just wondring if thier might be a more beefy setup without spending the $200+. i'm using 7,000 wt silicon oil filled to your specs.
ahhhh "mutant chassis". I thought this was a normal buggy. The Monster Pirate center diff has been used for several applications. It's not a "diff" at all. It's just a spur gear connected to a solid axel. People have used them in twin engine setups. the one thing i don't know is if it's a 1/10 scale spur gear or a 1/8th scale. the tooth pitch is different between 1/10 and 1/8 (ask wdavidhicks).
for a special project like that, I'd check out a solid axel setup.
