The kit comes with a 2 lb bottle but I also bought a 2.5 lb that U can see in the pic. I'm using .020 jets in the nozzles which should give me 72 HP at the crank. I also installed the NX kit which is similar on another Apex and we rode it last week in 2 ft of fresh powder and it rocks. Its my pops sled and he pulled me about 10 sleds in about 1000 ft with 40 hp jetting
Also this is the jetting calculator I use. It is the old school fogger setup but it works. I think this is why the NX and Holley kits give you more than their rated HP because these kits are designed for street bikes that rate the HP at the wheels. thus a 40HP NX or NOS is actually like 60 at the crank.
I have the same kit that will be going on a apex when the time comes. the only thing I want to do diffrent is run off the factory fuel system which I am pretty sure that it runs at 40 psi. and the jetting combo I was going to run is .012 n20 .008 fuel. it is a small shot but I want the bottle to last. the only thing I'm worried about is fuel issues with that small of a jet or getting cloged with somthing. any thoughts advise? thanks
I don't think you can get a jet smaller than .010 so that would limit you to a low pressure fuel setup. Or you could T into the factory line and regulate it down so you can use a larger jet. I am using the included fuel pump and it has worked great. I just wish my bottle was bigger. lol.
Fuel jet calcualtor. I would go a couple of jet sizes bigger than recommended just to be safe.
It is the Holley kit for a 4 cylinder street bike. It is not "turn key" I had to buy a lot of little fittings and parts to make it fit like I wanted it to. It's not hard just a lot of trips to House Of Hose.
If you noticed in my last picture, I had to modify the crankcase breather to accomodate the nozzle. It is made out of magnesium so you will need to find someone who can weld it. You can't get the nozzle to fit any other way.
So far I am very impressed with this setup. I have sprayed a lot of nitrous through it, and have surprised a few with my "stocker". lol
