Nitrous for Joyner, who's done it?

[huunz]

Ok, so it seems to me that if I'm going to have to rebuild the motor anyway, a little Sneaky Pete setup on the 650 might be fun. I'm thinking something to top the dune at Comp Hill, that kind of thing.

Has anyone built a N2O system for a Joyner? I figured I'd drill and tap the bottom of the intake with Fogger nozzles, put the smallest jets available in and hit it halfway up.

Anyone done this?

that sounds like it could be awsome but not a great idea but if you do it let us know

You're crazy. But a good kind of crazy.

As long as you put enough fuel to it you will be ok... a universal efi kit from NOS will work perfect

I was actually thinking, as I noodled it a bit, of two Fogger nozzles, one in each manifold runner, which would provide both the fuel and the N2O. The issue I can see is the size nozzle required may be much smaller than normally used.

Here's the math: 650 cc in two cylinders is roughly equal to 1300 cc in four cylinders, or 2600 cc in a V8. That's a very small displacement, and many nozzle setups are for 5700 cc or larger V8 models.

The EFi kit, I don't think would work, because the car is a carb setup. Maybe some Joyners are EFI, it would work on that, where you just add the N2O in a nozzle, and have the computer add extra fuel when the N2O is activated.

I really don't need the extra power all the time, just at the tops of dunes, so this could be the hot setup until the motor goes completely and I get the Silver Bullet kit.

Hmmm....

Oh, and my crankcase evacuation kit came while I was on vacation, that should add a tiny bit of power ;-)

Im sorry i assumed u had a trooper i guess... check out Highlifter.com. they custom build kits for atv's ans side by sides. They will prolly suggest an efi pump for the nos kit but they will run 2 fogger nozles and know the correct jet sizes

They make all kinds of kits for snowmobiles as small as 440 for sure that I have seen google nos for snowmobile mite help you out

A little research showed that the N2O kits with a pair of fogger nozzles and all the parts are more expensive than the Silver Bullet engine kit. And, I'd be adding N2O to an engine with cast pistons.... Maybe Silver Bullet first, then N2O..... In the meantime, I put the evac system partially in place. If I didn't want everything nicely painted, it would probably be easier

So, I've been collecting bits and pieces on eBay for my buggy nitrous system. Kinda fun putting little bits together to see if you can make it work. Crankcase evac really woke it up, by the way.
