GrayRacing Posted July 12, 2010 Report Posted July 12, 2010 ok guys, my cub cylinders are being sent off to millennium to be renikiled. my bike ran constitant 3.1s and 3.2s in 200ft. im wanting to stick a 25-35 shot of nitrous to it set a track record, whats the biggest shot of spray you can stick to a motor like that and how many tenths should it pick you up ? im just needing to know before i go too big on the spray and blow it all to heck.

lowriderb Posted July 12, 2010 Report Posted July 12, 2010 are you wanting a dry shot or wet shot? whats the compression, fuel, additive fuel your wanting to use, ignition set up ect.. Quote
GrayRacing Posted July 14, 2010 Author Report Posted July 14, 2010 are you wanting a dry shot or wet shot? whats the compression, fuel, additive fuel your wanting to use, ignition set up ect.. im gonna use a wet system, and my bike is running off alky and everyone tells me to use gas as a additive. and idk about the ignition. i have 180 pounds of compression in each cylinder Quote
Wheelman Chassis Posted July 14, 2010 Report Posted July 14, 2010 back the timing down to +2 or so, i would pick the fuel up from a seperate location( not the pingle valve that support the carbs ). make sure the battery you choose can support the solinoids,and the pump. meaning the psi from the pump does not fall to far when you click the the system on, set the psi from the pump flowing.. keep a good eye on bottle psi, its a big deal.... use gas for the fuel.... i would say a 35 shot is fine all day if you have good parts, a 35 shotis like dropin a bomb...you are going to have to gear, tire and bar adjust to optimize the spray. in 200 ft its all going to be how well you get the added power down in the first 75-100 ft Quote
RagunCajun Posted July 17, 2010 Report Posted July 17, 2010 (edited) Assuming timing is retarded enough and air/fuel ratio doesnt go lean, what is the next weak link? Piston strength, rod strength? Just curious because i have a 4mil stock cylinder bike on race fuel. I have a hotrods crank and i dont know what is the limits of my internals in terms of horsepower. I thought about spraying my bike as well just in 4th and 5th with a WOT switch and wet shot(5-10shot per cylinder). I would of done it already but kits are freakin $750+ Edited July 17, 2010 by RagunCajun Quote
makemefaster Posted July 17, 2010 Report Posted July 17, 2010 i just got a nitrous express system and the power sports tech told me not to worry about using gas as a fuel mix he said that it would mix just fine with the alky. he also said that i could run up to a 35 per hole with out changing head studs Quote
RagunCajun Posted July 17, 2010 Report Posted July 17, 2010 damn i never thought about head stuffs. I feel ashamed. That's a huge deal in the car performance world. Does ARP make head studs for stock or aftermarket juggs? Quote
Wheelman Chassis Posted August 2, 2010 Report Posted August 2, 2010 you can use alky for enrichment as long as your pump can supply the volume you need, and you jet the fuel side of the spray with the correct jet size. the fuel jet for gas and alky will be alot diffrent. Quote
Josh Z Posted August 19, 2010 Report Posted August 19, 2010 Look into a Boss noss kit. They come in a little box with the batteries already there and should always have enough fuel to cover the spray. I just bought a kit about 3 weeks ago. just waiting for the time to hook it up. its a way simple kit tho, call boss noss and tell them what you have and they will tell you what is safe. Quote
ree_ree Posted August 19, 2010 Report Posted August 19, 2010 i wouldnt run any more than a 20 shot on a 4 mill stock cylinder set up...but then again what do i know Quote
alcoholbanshee Posted August 19, 2010 Report Posted August 19, 2010 I have ran a lot of 50 shots on a stock cylinder setup..................................... Quote

Josh Z Posted September 14, 2010 Report Posted September 14, 2010 (edited) ok its all done just need to try it out... i will keep ya posted... Have you ran this yet? I think you might have it hooked up wrong? check the NPFI before you run that thing! never mind! That's your fuel splitter. sick bike! I'll have my updated kit next week!
