Nightrider Posted January 15, 2004 Report Posted January 15, 2004 How exactly do you increase fuel pressure on a carbuerated application????You stated your systems were DRY systems.This is where your making no sense. When I mentioned fuel pump,you said I was talking about wet systems,but now your telling me fuel pressure will make up for the extra needed fuel in a dry system. Shorty,am I missing something here,is there some info that your not telling us about.Are these banshees fuel injected?There has to be fuel injected from some point if fuel pressure is playing a role.Are these some kind of special carbs? This is why your not making any sense,We are not here to ridicule your Dry set-up,but your telling us one thing that conflicts with other points your trying to make.And when we question you,you seem to get all defensive.At first your post interested me and I figured that some of the added cost was from the manifold blocks.I agree they can be expensive.But the logic behind your system didn't make sense. The more you try to explain it,the harder it is for us to understand you. Like I said if your dry system works for you,then use it,but to come here and preach about the advantages of a dry system over a wet is useless.There is no advantage. Quote

Like I said if your dry system works for you,then use it,but to come here and preach about the advantages of a dry system over a wet is useless.There is no advantage. this is where your not getting it......there is no fuel to pump for the dry NOS..... The carb runs the exact same as it does without the nos. The pressure is adjustable from the blocks to the carb. This way you can adjust the enrichment externally. Thus being able to jet the carb in minutes. Now if you guys would have asked the questions before and not dogged this system telling me wet is better, blah blah blah....... then you would have understood it by now. Just my 2 cents. there is no advantage in your mind.... I guess the problem I am having is none of you guys have put NOS on a banshee.....or if you have it was several years ago. They are kind of like turbos.....you can put one on a banshee and when they run, good they run extremely good... but 75% of the time they break and or run badly. Quote
Nightrider Posted January 16, 2004 Report Posted January 16, 2004 Shorty,my main question is...what pressurizes the fuel.You keep talking about increasing fuel pressure,now you say you can richen it up externally.Are you just richening up the mixture?This sounds like your using a type of Dial-A-jet system. Is that what it is?If not what pressurizes the fuel. Try to be a bit more specific next time,it takes a bit more typing,but it helps people understand what your trying to explain,Most people that have no clue about nitrous and would never know the difference,but i'm very familiar with it.

Maybe not you specificly but all the same. The manafold block is adjustable for pressure to the float bowl.....the stem that attaches to the block is adjustable for nitrous to the carbs......(IE:how much) by dialing in the pressure (up or down) you can enrichen or lean out the fuel the carbs produce. So it is using the motors crankcase pressures to enrichen itself basicly.....but you adjust it at the blocks. Maybe next time Raxen can let you in on how it is done since he seems to know sooooo much about it. Quote
Nightrider Posted January 16, 2004 Report Posted January 16, 2004 You should have said an example could be seen on your website.Hell I don't go to those weblinks on anyones,you never know where there gonna send you(theres some sick people out there)Now I see what your doin.I've never heard of pressurising the bowls.HMM All of this could have been avoided,I think Raxen and bigboybanshee were ready to go "all backyard wrestling" on ya.No worries its under control now.

A dry system has one distinct advantage. Variable progressive injection. The amount of NOS ingestion and fuel enrichment is controlled by the CFM demands of the motor at any given point. Basically, the more throttle you give the motor the more NOS and enrichment fuel is delivered A wet system can be set in stages but a dry system is totally progressive Also auto compensates for temp, alt, and bottle psi. With a meth dry system it uses the existing carburetors and fuel system for enrichment. There is nothing else to purge other then that you are normally used too. But you will get better performance using race fuel if the temp is below 75 degrees or so. I run both systems. A wet system is a hassle with meth since you have to not only plumb but also flush it's fuel delivery system out in addition to the carb system. A meth system is temperamental be it wet or dry but on a wet system you must manually compensate for changes in altitude and temp. A dry system automatically compensates for these variables. A wet system involves more parts but is less expensive then a dry due to the manifold (two manifolds on a banshee) cost. I prefer dry systems with methanol. I prefer wet or dry systems with race fuel. I prefer dry systems for bracket racing (better consistency) I prefer wet systems for heads up auto racing (higher output potential) Here is a photo of Bill (Shortys) alky burning drag bike with a dry system installed. Only two builders have been successful building, tuning and drag racing this system. Shortys and KandT. BDR Quote

raxen Posted January 16, 2004 Report Posted January 16, 2004 Wow, just got back from dinner. It looks like I missed out on alot around here. Damn it, I love a good argument. Oh well, wet kits are the real way to juice it, anything less would be uncivilized. Quote
Brindley Posted January 16, 2004 Author Report Posted January 16, 2004 i have both kits dry and wet. i have experince with both, I would not refer anybody to dry (My Opinion) you can only presurize the float bowl so much before you have to jet up your carbs, which makes your ride run rich until you hit the juice switch. wet kits you jet both the fuel and the nitrous at the nozzle you jet you fuel if the right jets are installed you will not ever run to lean and will be consistant every time as long as you have bottle presure. very simple to jet there is a formula that tells you what size of fuel and nitrous jets to run for the hp you want. i have lots of experience with nitrous on 2stroke engines i have it on my 03' 800 polaris escape and on my 450 K&T banshee both with out problems, banshee has a 30hp shot and snowmobile has 70hp shot all my friends run this wet kit 2 and 4 strokes and they kill fogger systems. But mabey yours works, would like to see it in person where are you from. PS why does K&T have boondockers if yours is so good? Quote
bigboybanshee Posted January 16, 2004 Report Posted January 16, 2004 I think Raxen and bigboybanshee were ready to go "all backyard wrestling" on ya.No worries its under control now. LOL! Nah, I just wanted sense to be made of this...Although some backyard wrestling would do me good right now Quote
Brindley Posted January 16, 2004 Author Report Posted January 16, 2004 the bowl presure is what i was talking about, not the bottle presure. how much presure does the bowl create? thanks Quote
shortys racing Posted January 16, 2004 Report Posted January 16, 2004 the bowl presure is what i was talking about, not the bottle presure. how much presure does the bowl create? thanks I was talking about the same thing (bowl pressure).....I can up the bottle pressure with heat so thats no problem. Don't really know yet, haven't got a guage yet....will have one by the next time we run it. What i was saying is that I believe that the motor will fail before I turn up the NOS enough to have a bowl pressure failure. There is alot of adjustment left.... Quote
kenr74 Posted January 16, 2004 Report Posted January 16, 2004 Hey Shorty, I'm just up the road from you. How about putting a demo (free) system on my bike and then I can do some "testing" for you!! Quote
