I have been thinking about this kit for a LONG time. I am ready to make the purchase. How many of you out there are running this kit? I want to do this kit becuase it is the safest way to do NOS. MY questions are, how much is it? DO I have to get the bottle and all the equip needed to do it from JWT? I already have their ECU, so I imagine that I send it back for the NOS program and thats it. Can I get the NOS equipment elsewhere?
Does JWT have a package deal? I think i saw 50 shot kits for less than $500...am I incorrect?

Someone please enlighten me! ;)

Why is this considered the safest kit? I'd consider mine to be about the safest. Window switch and fuel pressure safety switch. What does JWT do to the ECU to make it safer?

JWT does all the things you're doing manually (fuel pressure, timing retard, window switch, etc) and makes them controlled by the ecu. It is simply plug-and-play, with very little tweaking on your end.

Which is attractive to the first-time nitrous user. Can't argue about that.

For those who are more automotively inclined, a good manual setup can be just as safe and easy to use. It just comes down to how much you want to do and how much you want to spend. :)

I agree with Greg, except for I have yet to see someone get more then 50hp out of a 50 shot of nitrous. IIRC the JWT 50 shot gave a little bit more then 50 on their SCC car. And I know Russell runs the JWT 100 shot and I think he got over 100hp to the wheels with it. It's definately a great kit. But as with most things in life, you have to pay for the quality.

I can comment on this as I used to have this same exact kit.

First of all, if you have a JWT ECU, you will need to send it back to them to get the NOS daughterboard. This is $450. You will also need to buy the NOS equipment from JWT, I believe this runs around $300-$350 or so, but I could be wrong. You get a 10lb NOS bottle, 14' S/S braided line, a solenoid, fogger, and a .036" size jet - basically everything you need to install the kit within a few hours.

Now for the safety features:

RPM turn on and cutoff: N2O won't flow if you have the switch armed and you are at WOT if you're under 2200rpms or above 7500rpms.

N2O-specific spark and fuel maps: Since you get a separate NOS daughterboard, you have a NOS-specific program which controls timing and fuel. And when you're off the juice, you are still optimized NA with the basic JWT ECU program.

Fail-safe mode: If for some reason, the ECU does receive WOT signals, rpm data, etc...the ECU will not power the solenoid on. Also, when everything is working right, your check engine light will come on to let you know everything is working ok.

All in all, for a first time N2O user, this is a killer deal. I really liked the safety features - one time I slammed into the rev limiter 2 times in a row while on the juice and the automatic rpm cutoff saved my engine. And this system has been dyno-proven (not by me though) to make +65whp and +100wlb-ft of torque. With your basic breathing mods and slicks, you will be well into the 13s with this system.

Good luck and happy spraying!

I thought the beauty of the JWT ECU is that once you have it,
ANY reprogram, turbo, NOS, was only $100? I cant see it being $450 in addition the the $595 I already spent...

Otherwise, thanks for all the info! Sounds like a killer kit!

Nope, it's $450 for the DAUGHTERBOARD. This is not a reprogram, JWT is adding an additional daughterboard to your ECU with the NOS program. When you get your ECU back, you will receive it with the daughterboard installed with about 3 wires coming out of it. Yes, it's expensive, but how much of a price do you put on peace of mind? It's safe and it works assuming your motor is in good shape and tuned correctly (i.e. timing at 15*, fuel system in tip top shape, etc.) Believe me, once you feel the kick of the N2O flowing, you forget how much it all costs. ;)

It is $100 for a reprogram, like from NA to turbo, S series cam program to C-series cam program, NOS control to water injection control, injector and MAF reprograms, etc...

Hope that helps!

MSD Window Switch: $85 (retail)
Modules: $19.99/pack (u need 2 series) = $40 (retail)
Fuel Pressure Safety Switch: $35 (retail)
Timing Retard: $Free if u have a gun, or a friend w/ one

If you don't know what you're doing, or having to retard your timing a couple degrees really bothers you, then go for the JWT program. Otherwise, i can't imaging spending $450 just for the daughterboard. My way leaves almost $300 (enough money for a purge, bottle warmer, and your first bottle of juice!)

I guess if you've got the $$$, and want the off-bottle driveability, JWT is definatly the way to go.

Yeah.. but I heard that someone *cough* is selling a whole JWT 50shot kit for a pretty decent price in the "for sale" forum!

Sure you can do manual timing retard.. but I don't think I'd want to have to jump out of the car and retard my timing every time I want to squeeze. Unless you like driving your car a 10 degrees timing :D

Or...you can add a MSD Digital 6 box and have the timing retarded for you, only while your arming switch is seeing 12v current. And, you can dial in the soft-touch rev limiter to hit *right* before your factory rev-limiter. And, you'll have a two-step launch rev limiter, to boot.

$297 at Summit. :)

Yeah yeah :) But then again.. I like having my ECU when I"m not on the bottle. I guess its up to the user. I wish JWT could do a progressive setup.. oh well.

I like Greg ran my old set up just like he did. I had a very good turn out with my set up. But JWT is the way to go if you can spend the cash. If you are mechanicaly inclined then do it anyway you think better. But if not deffinitely go JWT!!!

Luis, I did not intend to come across as putting down the JWT setup. Just showing that, indeed, there are many ways to skin a cat.

The JWT setup is the slickest way to skin this particular cat, IMHO. :)

If you like plug-and-play, with a host of built-in safeguards, then by all means get the JWT setup. It appears to be all but fool-proof, from what I've heard.

Yeah, I used to bother JWT about doing this for me all the time. From what I understand, the main problem is building a solenoid which can take the abuse of a progressive system. I think the Jacobs Mastermind Progressive Nitrous Controller has the same problem.

Why use a 'progressive' NOS controller that PWM the NOS solenoid?

Why hasn't someone just come up with say 3 NOS solenoids, each a different orifice size and actuate them in sequence depending on RPM?

like turn on the "30" shot solenoid from 2000 - 3500 RPM
the "40" shot solenoid from 3500 - 5500 and the "50" shot solenoid for 5500 - 7500 RPM? 120 hp shot in total, but in 3 increments.
