how much is too much?

[griemar]

Just curious, is there a such thing as too much WOT running? I have a GT2 with a stock .15x and I dont want to burn it up with too many WOT runs. Also, anyone know the avg life span of that engine as in how many tanks/gals it takes till it starts needing a rebuild and/or replaced?


Thanks in advanced.

P.S. I asked a few questions in the stadium truck section and no-one has responded yet. Dumb questions or just no-one really knows? "What breaks for GT2's?" is the post.

Thanks again.

There isn't really a set life span for these motors. It varies greatly between models and manufacturers. That said if you are running WOT most or all of the time then whatever the lifespan of that mill would have been is going to be reduced, but I don't think there are many of us here who don't beat the ever loving snot out of our rigs on a fairly regular basis. Be as nice to your mill in other ways as possible always stop it at BDC, use after run oil, make sure its not running too lean or hot etc. When she needs a rebuild, do it and then beat on it some more.

Thanks for the info. wasn't sure what BDC was at first, but some quick research and i figured it out. Guess i'll have to start making sure the mill is BDC from now on when i shut down for the day.

Running WOT on a lighter (and 2wd) rig will blow a non-high end engine in a much shorter time.

On light/2wd rigs, the engine is actually allowed to wrap out much higher due to lack of constant traction and minimal moving parts to sap power. Verses someone running something like a savage... or revo WOT across a park.

I'm just saying that because I've noticed on my jato that my OS18TM hits much higher RPM's much more quickly and easily than it ever did in my revo. Due to mostly the lack of traction a lighter 2wd vehicle offers. Even on concrete, there is just so little mass to the vehicle and drive line, that the engine can hit really high and damaging RPM's pretty easy.

Typically the con-rod snaps or the piston gets a hole burned in it. Now, with a $300+ italian mill, it can handle higher RPM's better and for longer periods of time due to how the engine was made and the tolerances of the parts.

A typical RTR mill just isn't built for that kind of abuse in most cases. They are built for reliability, easy tuning and ok power.
