Yes and Yes. You get rid of that mid lag the 8 port suffers from and it improves the accel response. If you want one PM me.

BOOOOOST IT BABY! YEAAAAA!!!

I just put a Nitrous bottle on my JP FX and it absolutely loves it. 8.0 HP at 120,460 RPMS. Just gotta replace the rod every few rpms. lol

Sorry.


The boost bottle may help overall- but don't ever let that tubing come loose- otherwise ~POOF~ Goes the motor!

This is not a bottle its a fan on the back of the engine thats blows air into the crankcase much like a supercharger!


120,000 rpm that cant be good for any engine

Ohhh you mean the Hyper "Turbine" gimmick-

I have no experience with that thing- Might want to ask Grahama.

I thought you were talking about a boost bottle.

NO!!!! IT IS A BOTTLE. NOT THE TURBOFAN!!!!! and it can only be fited to the newer crankcases that have the blanking screw on the left of the carb throat. Do a bit of research on the matter first plz. You made me mad.
