hot rods or vito's 4mm 115mm crank

[Tedder]

Other than two OEM cranks (which are very good quality imo) I've only run Hot Rods in my drag motors under 10mil. Each got upgraded outer bearings from the original  Taiwan's.

Over the years I've had a few welds crack but never separate like the one in your pic and one large end rod pin that snapped clean through. Luckily it busted when I was doing my dry hop before a run.

I've never had a connecting rod snap.

 Did you use the TZ Baron on the clutch side and the max load Baron on the flywheel side?

With 2.68 straight cut primaries I used TZ's on both the clutch and stator side but with my sustained high rpm 1/4 mile runs light brown color always showed up on the inside races. In never saw any galling but the color obviously indicates skidding and heat buildup. With barrel rollers they have more drag also. I'd pretty much decided on going with Max loads even though they're prone to cracking races if subjected to detonation which I sometimes get with my alcohol motors and they don't have near the TZ's load carrying capacity but for better or worse I ended up going ceramics this time. We'll see if that was a wise decision or not! 

Personally if I was doing a gas trail type motor I would go either Koyo or Max loads.

Ok gotch ya. Thank you for the input, I really appreciate it. I would definitely like to know how the ceramics turn out.

Great info.

i used to build mountain bikes (totally different I know) but once I went to ceramic bearings in my hubs I never went back. They lasted forever and showed no wear. Definite noise difference though

Don’t ever buy anything Vito’s. It’s now owned by Rattle Can Ray.
