I went ahead and put this nitrous kit together on the scoot. using a .018 jet spraying dry into the inlet....initial tests are promising!...very noticeable power at the push of a button is a huge plus! ....I hope to get into the 3's (50m sprint) with this setup......right now in the mid 4's on motor. There doesnt seem to be too much info floating around concerning GY6's and nitrous ....so Im just playing it by ear here.  
 Here is a video to demonstrate the difference with and without nitrous. 6-7 1/10ths difference in a 50m sprint! |

Nice! Try upping to a .02, if it improves cool, if not I don't think it will hurt.

Like the lowered and stretched look you have and the bars.
Just from what I have read mostly the racers use nos but they are rebuilding motors a pretty good bit also. Hope you can find a good balance to keep it somewhat dependable. I see you put the nos jet size but how much hp gain do you think you're getting?

I honestly don't think its much more than a 4-5hp boost...I am spraying in the inlet before the carb....so its probably losing a bit of effectiveness as it heats up....it would probably be a more aggressive hit if it were in the intake manifold...my typical rule of thumb for power adders is if you stay around 50% of overall power added then you can maintain some reliability. |

Yes I have been looking at the scooters from PR.....they are VERY impressive....do you have any advice for how much nitrous a 172cc 61mm bore GY6 can handle?....

We run nitrous with custom made pistons made to handle it. such as this JE Piston made to handle a 35 Shot. Also run Big bore kits with very thick cylinder walls, Forged Crankshaft rods. Welded Crankshafts.  Also i noticed on your setup is different from what i have seen here. Most drill the Nozzle in the intake manifold after the carburetor. not before. |

That looks awesome! I just want the front plastic. I have a front body plastic off an old spare scooter that I may try to configure to fit. My Style is the Handsome Boy ViP style, it is easy to take off. I will try this today.

Good to know....I am using a 61mm bore/piston with stock rod/crankshaft......I need to step up to the PR special recipe!!....Hook a brother up!... I cant imagine how 30hp extra would feel on this 15hp scooter!...ha!! |
