mugen power booster INS box
 

Had lots of temp problems with the mugen Ins box.
Had to run to lean to get some performance out of the engine, resulting in way to high temp.
Someone suggested to put on a "normal" box, engine suddenly run to rich, and after adjusting, temp was back to normal.
Mugenfilter was clean.
Anybody, comments on this?

A couple of people at our club were running them and noticed a power loss with them. They went back to the novarossi or rb boxes and their cars ran much better. Seems like the Mugen INS box is more designed for 10th scale.

thanks for your reply..
I run 235mm even with 2,5cc it is no good....
