Wet vs Dry nitrous qestions
 

What is the difference between a wet and dry system? which would be more user friendly with less chance of problems?

Is there an approxiamate cost?

How large of a shot could i run on an HCI car?

Wet kit: Supplies its own fuel
Dry kit: Does not supply its own fuel. It spikes your fuel pressure to provide the additional fuel via your injectors.

I'm not a nitrous expert by any means, maybe Nickm50 will chime in, he's been running it for YEARS and has experience with both kits and has had three nitrous "assisted" vehicles including that S-truck you are familiar with.

You have a hyper piston motor, so, you are going to hear a lot of different answers in regards to that part of your question. Some say no more than 100-shot, others say you CAN run a 150.....etc. Just don't detonate it, or bye-bye piston(s).

i've already had some detonation, but on the stock engine it wouldn't have hurt it....with nitrous....bye bye pistion!!! that is why i will be taking it to get a tune next year to make sure everything is working properly!

IMO, a dry kit if always easier and safer than a wet kit, i get flamed for it, but usually by people who don't know any better.

Dry kits are indeed simpler and will work for most people just fine. Now a guy who wants to tune more power then there is too be had, well BOOM!

guestimate on price...no labour

Looks like you wont be able to run nitrous, our cars love detonation lol

With good fuel and a tune you'd be fine with a dry shot. If your running over 100hp make your best off to run a better pump. It can be done with the stock pump but it isn't smart.

Start small and tune what you have before stepping up. I have run this stuff forever and have picked up over a full second with a tiny 75hp hit. If you put a kit on and see little gains, re-sist the urge to jam bigger jets in and figure out your problem first.

I also think a dry kit is a safer bet, I would run 100hp max, with that you could get an adjustable fuel press. regulator and see if it will do, if not, you'll need to upgrade your injectors and pump. For a basic kit, I'd say you'll be looking at $700-1000 depending on the brand, used kits can be had for around $500+/- $100.

I have a brand new stock pump and an ACCEL adj regulator

Well, I'd try and have it tuned like that, if it goes lean, you'll need to do injectors and calibrated MAF, if it's stock most likely it will be fine, you should be able to adjust it to flow enough fuel, but you never know-every combo is different and especially if you're doing a good H/C/I combo-you'll probably need to upgrade injectors.

I should mention that the stock pump is fine for a stock engine, if you add heads and such then you should get a pump first anyways.

for a new "user" the dry kit is definately the way to go! not much you can really mess up and is stock engine friendly. up to a 100 shot you don't need anything but the kit, after that as mentioned by most every one else you will need to upgrade your fuel pump. you shouldn't need to have it tuned to run a 150 shot, just buy a good fuel pressure gauge and watch for fuel pressure drops. The smaller kits (up to 150hp dry) are calibrated for stock injectors and fuel pressures. You just have to make sure the pressure does not drop (engine will go lean real quick). the rule of thumb is 2 degrees timing retard for every 50 hp.

also in a 95 I would try 8 initial timing on a 100 shot, with ultra 94 just to be safe!

make sure you invest in a good fuel pressure guage first!

if you plan on using nitrous i would just get the kit first, then do heads cam and intake later, the nitrous alone will give you more than you are looking for at this point! It takes some getting used to.

I'm running a dry kit.It's a Zex kit on a 100 shot.With my combo feel I should be way faster than I am so far.But it takes time to learn the stuff but it is a rush.

thanks for the infor guys....im gonna do a little reading on Nitrous before i go and buy a kit!

zex makes a good system....look online at american muscle....to your door about 700 bucks for the 75 to 125 shot....and you can order bigger or smaller jets....100 is max on regular plugs,stock fuel pump etc...and i like the wet system simply because there is a much less chance of detonating because the a/f is evenly mixed with the nitrous....dry kits get sprayed before the throttle body and will never get mixed evenly going into the cylinders....jmo

Take your time and learn all the Do's and Don'ts of nitrous. A dry shot is safer because you will not have puddling in the intake, but you have to rely on your injectors/computer to increase fuel. A wet shot makes better power, but a chance of puddling on EFI intakes can happen.

Wow... 4 month old thread resurrected. Check the dates before you post. AND NO WAY IS A DRY KIT SAFER

OK Boss! I see you responded to this thread that was started in 2006!!! Only about 4 yrs later, Wow!! Check the years before you post!! And your on my azz for posting 4 month's after your post??????? LMAO!!!!

Excellent tech info from Nitro Dave from the Nitrous Outlet.

Wow an oldie but goodie lol

I'm sorry I had to be an idiot towards him. But he responded almost 4 years after the last post in this thread and he attacks me for responding 4 months from HIS post!??? :suicide:

Ya...if you look it was one of my very first posts ever on this site. I didn't know they were dated and I was absorbing every bit of info I could. At the time I didn't know there were dates on em. Newb mistake. What's your excuse

I didn't attack you. I did what every guy in this site has done to me when I resurrected old threads. You American or something

I don't follow the herd!:D I like threads about nitrous.

K...so we are clear here. No one got insulted and we are all smiles...please. I don't have the heart to argue today. Hehehe

all is good boys
