My friend owns a t-maxx and thinks it has 37,000 rpms. I told him no it dosen't because the truck would be alot faster. i said it might have 26-28,000. I have looked left and right, up and down and can't find the rpm's any where on the net. Will someone please help me.

well its a small block engine so chances are it will hit well over 30,000 rpms (max). but i have never seen specs for any traxxas engine either.

The HPI Savage 25 does 38,000 RPM max and is it faster than the T-Maxx? No.

RPM's don't mean much, unless your are increasing them. Buying an engine with a higher RPM usually means sacrificing power someplace else. In the end the speed is determined by how large of a gear the engine can push, not the raw engine RPM.

Actually, traxxas has claimed roughly 40,00 RPM's on that engine. Any good small block will pull more RPM's than a larger displacement engine. My sons maxx will out run any big block truck i have in this RC room. RPM's equal top end speed. The advantage to high RPM engines is gearing for torque, and still having RPM's left for a good top end. The opposite can be said about a big block. While a Picco .26 doesnt pull nearly as many R's as an average small block, it has the GRUNT to move the truck with larger clutch bells, and smaller spurs.

Ive seen specs on the engine in the tmaxx that state up to 49,000 rpms for the stock 2.5
