N20 and fuel reaching the chamber at the same time is done with jetting and fuel pressure. That is why bottle pressure and fuel pressure are always keys to correct tunning. I will say that I quit using the little fuel pump that they sell in their kits. I used an aeromotive a1000 fuel pump and a regulator plus a return line from the regulator and a air bleed for the fuel coming right off the fuel solenoid going back to the fuel tank. Plus I always flowed my system before I made a pass. I tuned my system to run a 1000 lbs of n20 pressure at 7 psi free flowing fuel pressure. Once n20 pressure would decrease I would re flow the fuel and adjust accordingly. Would only take a couple of mins. To some that may be to much, but for those who want to make power it is just a little time for the outcome.

If you inject both nitrous and fuel at the same place, at the same time, the lighter one travels faster, its a matter of physics. Fuel nor nitrous pressure can change that.
I find it ironic that most people that like the holley setup run short runs, and usually have time to adjust between races. Those of us without that luxury, choose other setups that can handle many long runs, one after another.
Lets do a test. At Ds days, lets have someone bring there wet system, any of them, and we will bring both a boonies kit, and a boss kit, and we will run them back to back, until the bottles are empty, and see which one holds tune the longest. No adjusting in between races. That would be a pretty good example of what system runs the best, the longest.
Like I said earlier, if you are running short runs, or have time to tune between runs, the "wet" systems are the ones to have.
I also ran a 25 shot on my stock motor with well over a hundred pounds through it, for over a year, with not a single issue. People under estimate the duability of a stock engine.
By the way, Boondockers has been on the fastest sleds many years in a row, competing in the top hill climbs in the country. Much more money to be had then a weekend atv event. Wonder why they run it? I'll bet consistancy.

I also got to thinking, wonder why most all 1/4 mile drags run the "wet sytem"? Short runs maybe? Time to tune between runs, or add bottle pressure? Maybe. Well you get my point,lol!
I really do think its just a matter of different worlds. Like using a rigid frame for hill shooting. Sure it might get the job done, but I dont want to be the one to try it.

In a matter of physics, restricting the lighter one slows down the flow rate, restricting either one slows down the flow rate. Better question would be, why do all 1/4 drags run a "wet system", or the fast ones at least. See my point below in my other posts.
A dry system is limited, Dry systems are for slow street cars. I dont think you will ever see Pat Musi Running a dry kit on his 6 second door slammer......

thanks for all the advice. listen guys. i got a few more questions. lets just say i went with a boondocker system. is it worth it for me. i ride 90% trails and am in the mud alot. i do like to drag and open it up on fire roads too but only on occasion. i am happy with my power now but like i said earlier i want to fend off the rappy 700's. hightower mentioned an extended swinger and i value his opinion. do i need one for the juice to be effective? i like my stock swingarm for trails. what kind of reliability issues will i have to worry about? valves and things like that. also i am not the guy who heads back to camp to retune his carb if it rains and the temp drops ten degrees. in fact i dont even re-jet for winter in northern ohio. i just ride and love my reliability. dont get me wrong but i love to tool on the ds but when its ride time, its ride time. i only fix it if its broke during that time. if i got to beat the heck out of something to finish riding time, thats what i do. ask hightower[img]i/expressions/face-icon-small-wink.gif[/img] anyway guys is it worth it for me to run some happy gas thru my bike?

In a matter of physics, slowing down the flow rate does nothing but slow the amount. If you are injecting it later than the fuel, then yes, it will reach the said point later. Flow rates control amount, not time.
As said earlier, short runs=wet. I dont know who it is you just mentioned so I cant comment.
