its the same size as the TM323 but this version has dual scoops on the crankshaft which they call a bi-turbo crankshaft. And it has 7+2 Porting whereas the 323 had 5+2. Should be a sweet mill!
Any feedback on this engine, from what I hear, the 323 is overkill as it is, would anyone advise against getting this 7 port version or should I get the older 323 5 port.
I've chatted with a few Revo owners with the new TM523 and they love it. They did mention how much power it had and the gearing took a while to get right. I didn't get to ask him what gear setup he had. Does anyone here have the new TM523 yet on their Revo?
