So, how do we "frog" a stock GY6 150 ?  By  Noneshere (Read 2,442 times)

The 150s usually come with 13/40 gearing so if it does a REAL 60mph that is better than most. And if you go taller for more top end you will loose some of the bottom zip. Normally stock 150s will do 50-55 real mph. You already are rolling with 11 gram weights, the 150s run good with 11-12 gram weights. What you did not mention are the RPMS at say 40, 50, 60 mph, that will tell tell you what you need for more zip at the bottom end. To punch out of a hole like you seem to want you need power to move the weight, and that requires more low end torque which more displacement is needed.

He is talking about CAMARO burnouts (NOT STOCK) no matter what he does. He is already running 11grams and I know what 11s do I also know what 10s will do, so to do something of what he wants he will loose top end.

Alley is right , his rpms will tell everything " like wether he has any room left at top end for improvement or not "
