Dyno Results with 200 Shot

[HI-NOS-Viper]

Yes plumcrazy again you are exactly correct. Of course by the time I realized that, my dyno runs were done and later on picked up the different jets. I just wish the kit would of came more than it did in increments of 50.

same thing happened to me, thats why I keep them all in stock now....lol

burnhamb, What convinced you to go with a wet nitrous kit instead of say a propane-nitrous kit? I'm assuming the more attractive price tag of the wet kit was what sealed your deal. My reason for asking is that most SRT-10 owners that I have spoken to about nitrous believe that any Wet kit with a 150 shot or more will drain the stock fuel rails and starve the engine of the normal amount of fuel it would use causing a spike-lean condition that can cause detonation and ruin the engine. I believe a big wet shot(150+) can be very safe as long as you use the proper fuel system (better than stock ie. upgraded rails, pumps, and injectors)and have a proper tune. I may have been converted already, but I believe that the nitrous-propane set-up is a better kit for a stock SRT-10 because you are adding extra fuel in the form of propane, thereby, not taking any additional fuel from the fuel hungry V10. Not to mention the torque perk that the propane offers

Well the reason was not price tag, I am not cheap by any means and will take no short cuts, but tend to act faster than I should at times. The kit on NX site looked like it would work for what I wanted, more HP, and would not take that long to install. That and at first I didn't plan on running a 200 shot all the time, but 150 at the most, started with just 100(got use to 100 pretty fast)

Than I did a search on this forum and saw a few members running 150-200 on a stock fuel system and stock components with no problems. Well I have learned from others after that there may be some things I should consider especially if I'm going to constantly run a 200, especially on a car like this, I don't want to take any chances. Like you have mentioned, a propane kit, Nitrous pistons, and a progressive system so the 200 doesn't hit right away maybe causing drivetrain issues, and well just wheel spin. If anything, I am not running lean, but rich at least according to the dyno's.

I was in a bit of a hurry when I got home on vacation, I am a contractor working in Baghdad, and was able to take 2 months off(lucky to get that much at one time), so I was able to get a Viper while i was home, had to register it, of course had to spend time with the Fiance, got use to driving the stock HP, wanted more HP, and wanted a fast way to get more HP. After i was limited enough on how long i would be able to drive the car,

I didn't want the car in the shop the entire time I could of been driving it just to make it faster. I am now back in Baghdad and when i get home, I plan on upgrading the pistons and getting a progressive system, and taking the time to get everything done right. Do you have a link for the propane tank? How easy would that be to tie into my existing system? I also plan on running a second 10 pound bottle, I hated having to fill that thing up about everyday

I have considered many times the route you took with the wet kit since I already have a GM wet kit off an 02 T/A from a couple years back that can be easily modified to work on my srt-10. I haven't done this yet because as I did research on big shot wet kits, I noticed many SRT-10 owners tend to steer clear of 150+ wet shot due to high risk caused by cast pistons and fuel stravation. The progressive system you described is a good idea as it is less stressful on the car overall in the lower, more violent gears. The progressive system is just more costly and I don"t see a need for it unless your car is for track and you have the suspension & tires set up for it. Personally I barely track my car and don't plan on spraying from a stop as it is too stressful on a stock drivetrain. As for the propane tank, BTR offers a small 5lb. tank good for at least 60 1/4 mile passes when full. I have seen other small tanks varying in size, just do a search on google. Propane is 119 octane which greatly reduces the chance of detonation, being a gas, it mixes better with nitrous than fuel does and atomizes better in the intake manifold, and you avoid fuel puddling which can cause a backfire and blow your intake manifold apart (happened in my T/A). If you want to spray constantly on your large wet shot, you will need at the minimum forged pistons, and you will eat away at your stock clutch but it should last a while as long as you stay away from sticky tires. You can add the propane to your wet kit easily, I believe Tom Welch at BTR Performance offers a kit that converts your system from gas/nitrous to propane/nitrous. He also offers a crazy kit for the bold that sprays nitrous/gas/and propane all at once, but the gains are rediculous and I highly doubt any of the stock components will last long under such extreme stress. Anyway, goodluck in Baghdad, and I hope you come back home safely and bring the beast down to the 10's safely or better
