I am considering purchasing the JWT complete NOS setup from Cattman Performance. Does anyone use this currently? If so, do you think this would be a good way to go? It sounds like most everyone puts together their own system, this one from JWT seems pretty complete. Any help would be appreciated.

I emailed Cattman about this. I am also considering this upgrade.


This is the message:

Sorry the JWT ECU/N2O kit thread ran cold before I got a look at it, I can't
even begin to keep up with the forums along with everything else...

I'll be happy to tell you anything I can about Jim Wolfs really cool ECU-driven
N2O setup. It involves 3 main elements, the basic JWT ECU upgrade, their N2O
module (which also mounts in the ECU case) and the N2O hardware, which can be
purchased from them as a kit (made by NOS) that is specifically for the JWT
setup (i.e. it doesn't include any supplementary fuel solenoid, lines or jet) or
assembled from parts from other suppliers of Nitrous systems if someone knows
what they're doing and follow JWT's specs.

What sets this system apart from all others also makes it far safer, and more
efficient. Its a dry manifold system, because the ECU directs all fuel through
the injectors directly and evenly into all the cylinders.

[The long runners of Maxima manifolds are terrible for wet-manifold N2O systems
because the fuel is delivered unevenly to the different cylinders, meaning that
the fuel has to run way too rich (too avoid excessive temperatures) and this
really steps on the power.]

This 65-shot system runs as hard or harder than some 100-shot sytems I've seen.
The ECU comes back to you with a wire that runs to the N2O control solenoid and
another wire to a microswitch that is used to arm the system. When you're ready
to go, you flip the switch and floor it. The N2O won't kick in unless its
floored (the ECU senses this automatically, so this part is fool proof), and not
until the rpms reach 2500. When that happens, the nitrous solenoid opens up and
the fuel mapping function shifts to the nitrous module, which contains a third
set of fuel mapping (in addition to the stock one and the one that runs from the
ECU upgrade daughterboard).

In addition to the other technical advantages, the neat thing about this setup
over other N2O setups is that you have the benefits of the JWT ECU upgrade all
the time, plus N20 when you need it.

Purchase works like this. You can put up a core charge ($700) in addition to
the purchase price and they will send you the ECU for your car, already set up.
You send your stock one back (w/in two weeks) and the core charge is credited
back to you. Or, avoid the whole core charge by just sending in your ECU and
they will turn it around in about 7-10 days (sooner for just an ECU upgrade).

Price of the ECU upgrade is $565 ($595/JWT's price), I sell the ECU upgrade and
N20 module together for $950 ($1045/JWT) if you want to do your own N2O
hardware, and the entire system is $1495 ($1640/JWT). Typical N2O system
extras, like remote bottle shut-off, heaters, blankets, etc. are not included.

That should about cover things, but let me know if you have any more questions.

Don in Texas uses the JWT NOS kit, BUT... It's for the 95-96 Max only...
