GRP .21 Tuned Engine
With this engine I'm allowed to run 20% fuel right as long as I get the right plug for it and not use the turbo plug that comes with it?

RE: GRP .21 Tuned Engine
It'll run as is.
|
RE: GRP .21 Tuned Engine
As is meaning that I can run it with the turbo plug and 20% fuel?
|
RE: GRP .21 Tuned Engine
Yes
|
RE: GRP .21 Tuned Engine
Thanks alot.

RE: GRP .21 Tuned Engine
I reckon this engine is shimmed for 30% fuel and lot of people are using the OS P3 plugs.

If the engine uses turbo plugs there are 2 things you must remember:
1) you cannot use regular plugs in an engine that uses turbo plugs without putting on a standard head button & 2) I don't think that engines that use turbo plugs use shims (please correct me if I am wrong on this one). www.focusprinting.com |

Excuse me for being a little out of the loop on this being new to the sport but where do you put the shim?
|
RE: GRP .21 Tuned Engine
under the cooling head, they sit on the top of the crank case, and when u put the cooling head on, it sits on the shims, and thats how u get the clearance.

Gotcha thanks a lot......... Got a question about engine I'm currently running, I have the hyper .21 race engine and it has a head shim on it, would I need to remove it due to the fact that I'm using 20% fuel and a MC8 plug because I have been having some serious problems trying to break this thing in?
