The GX-7R is renown for it top end, so I think it will like it a lot

. In a straight line drag race it would be one of the quicker motors at the top end on the market.
If you are doing a lot of WOT running just run it a tad richer on top. Not so itīs blubbery, but just to make sure it gets enough fuel through with the constant WOT running. It will thank you for it.
