The results are in. I added the #7 converter, recurved the ignition with the Crane kit and added nitrous to my 385 sb. The ignition and converter made throttle response and seat of pants feeling awsome. You can light the tire( Freewheel / Smoke ) at anytime under about 50mph at will. I have only fired the nitrous once and it lit the tire at about 65mph. A very satisfying series of modifications! Crazy Rick rode it at the airport yesterday and almost burned the tire off :twisted: . When I figure out how to post on this site, we made some great pictures and video of burnouts. See some of you at Daytona :?:

BTW, We did all the work in my basement and the hardest part was getting the carb linkage(choke ) to clear the nitrous plate. Just hanging on the edge and then expanded with heat so the throttle would not return to idle. First ride around got exciting after it heated up and it wouldn't idle under 2300rpm! :oops:. All well that ends well.

Ya baby, I can see that smile on your face now. I can see I'm heading to nitrous on my baby in the not so far away future. To much WOW factor to pass up while I'm still young enough to enjoy it!!!!!!!!! Can't wait to see the burn out pics. Steve

Hi Guys,


Yes, I am still running the 230 Avon. I'm not sure that I want any more traction yet :D . It wasn't the frame causing the problem on the nitrous installation, it was the plate being wider than the manifold and (barely) interfering with the linkage. The problem got worse as the aluminum plate grew with heat expansion.

Lamont, thanks for posting the picture - I figured out the url stuff but couldn't get it over to your server. Thanks!!

NOS Sniper

It is the NOS Sniper system. It comes with three jet sizes - 100,125,150. I have the 125's in mine. BTW - All the smoking was done with the nitrous off! The converter and ignition changes go a long way toward making the SB's a lot of fun.

Phil,
I've done the ignition and converter changes already. You're right that they "wake up" the bike. I forgot to ask :oops: ........what size bottle and where'd you get it. Did you get the bottle mounts at the same place? Thanks again for the info!

Bottle Size

The bottle size is 2 1/2 lb. It is mounted on a very neat bracket on the shock. The basic system with mount was bought from Mountain Boss. The price is very dependant on mount and bottle finish - Chrome COSTS :shock: !! The Sniper system can be bought at most any good Hot Rod shop. You will have to customize the length of the solenoid fittings to make them fit under the tank. This is no big deal, you just need to find 3/16 compression fitting ferrels(?) and cut the steel lines that are premade in the kit. Easier than it sounds. Great fun so far.

Phil,
Sounds like a great installation! I know you are trying to figure out how to post pix on this site. When you figure it out, would you post a picture of your 2 1/2 lb bottle installed?

I've seen the 10 lb bottle installed on the rear shock, but not smaller one mounted on the rear shock like you described. Do you have one on each side?

Also, do you feel as if you have enough laughing gas with the smaller bottle/bottles? I have read some comments saying that the 10 lb bottle may be required for the big V8 when a few shots are planned for one evening.

Thanks,

Bill

I just bought a 2-1/2 lb chrome bottle and bracket from Marv at Chopper City. The bottle and the bracket were right at $500. Marv said the small bottle is good for about 24 seconds and a normal "blast" would be about 4 to 6 seconds.
I have not installed mine yet but I also bought a sniper system. Sounds like I may need to do some adusting.

Phil, What did you use for your arming switch?

Switch and pictures

I will make a picture of the bottle on the bike today and post. Crazy Rick put two of tem on his 502! Consumption rates published by NOS are 100hp=1lb @ 10 seconds, 125hp = 1.25lb @ 10 seconds, 150hp = 1.5lb @ 10 seconds. I don't think you can hold on for more than 4/6 seconds :twisted: .

I used a waterproof toggle mounted on the side panel for the arming switch. The switch that came with the kit didn't look as if it would stand up to any weather. The microswitch that came with the kit that mounts on the carb stud appears of good quality and I am using it to fire the nitrous at wide open throttle. Have fun.

Phil,
Did you have to customize the length of the fittings, etc. with the kit you got from Mountain BH, or was eveything ready to go? The price of the Sniper kit from Summit is considerably less, ($369.95 + shipping) but if Mountain does all the work for you, then maybe it's worth the price they ask. Thanks......Don

nope!

They just sent the standard kit. You still have to make it fit the Hoss. BTW - nitrous isn't much good in real cold weather because it lowers the pressure by a bunch. You would need a heater "blanket" to get much use out of it in real cold weather. I guess the car guys use the blanket.

Phil,
The same can be said about me! :)
So I'll only be using it when it's nice and warm out. 8)
Thanks for all the info!!
