Super Jet Why doesn't my superjet rev as fast as other ppls

Location

I have a 2002 superjet Freeride porting.175 compression dual38s r&d dry pipe running completly dry except the stinger. Stock ignition no rev limited and timing advanced. 14/18 concord prop stock nozzle n cone. I was very happy with my ski until I rode a couple others. No matter the setup dry pipe if b pipe they both have stock 62t motors with 185 compression no porting. Their motors seem like they pull thrue the mid range rpms wAy faster. Any suggestions on what area to make changes in to get mine to Rev up faster. Different size nozzle and cone mabe a different prop? Thanks

All of the above listed so far are good. I think you are over propped. First thing I'd do is get the Hooker 9/15 from Impros and then sell your concord prop. That alone will give you a massive improvement. If that doesn't give you the power you desire, there are plenty of other things to do. You can bore your reduction nozzle and get a stubby pump cone. This gives you better hole shot but at the expense of top speed. You can do the lightweight flywheel and epic or MSD enhancer but I still think total loss ignition is the way to go if you want the most hole shot possible. However, you'll have to charge the battery every couple rides.
