i want to run a 75 shot and nx says that the fuel jet to use is #22. what if i use a #24 just to be on the safeside with fuel.would that help the need for fuel? or would it be a problem? if that doesnt work then what do i need to run a 75 shot safley? meaning not wondering if my engine is gonna blow while im kickin some rsx-s or wrx ass.[8D]

thanks

I run the NX 75 shot with no problems Just go 2 sizes down on your plugs and make sure you up 92 + octane and you will be fine. I also use a wot switch.Make sure you only use the jucie
4000 rpm's and up.

I thought it was 3000 and up.

I agree with all that. I would also add a fuel pressure safety switch to the car ( about $40), it will shut it all down if the fuel pressure goes to low. It is a nice safety to have. 2 heat ranges down on the plugs is what he means, and use a copper electrode plug. And as above, ONLY 92 or better octane. You do not have to have it, but a RPM window switch to keep you out of the rev limiter is a good idea ,too

Upping the fuel jet one size is not a bad idea, it will richen the mixture and make it safer. It will lessen the HP of the hit a bit.

thanks guys for the input. those safety switches sound like a good idea. how much does a rpm switch go for? and do i have to get it from nx?

i went to napa and they didnt have copper plugs so then i drove to checkers and the only ones they had were these champion ones. are they good enought to use? and the guy did know if they were 2 steps colder. how do you find that info out? i know these questions are lame but thanks for the help

The plugs you want are Motocraft AZFS22C you can get them from the Ford dealer or anyone else that sells motorcraft also check with the site sponsors to see if they sell them> I know Focus-Power uses them its the same ones Tom uses on his turbo motors[thumb]

If you cant find any I have a 2 extra sets I bought so I would have spare ones since they were hard to find.

Yes i use the AZFS22C plugs in the SVT but in the white car i use a custom plug that we make
by taking another plug and machining it to work , it is a much colder plug than the 22c

tom-

do you sell the custom plugs?

RPM switches are about $60 or so. Several companies make them. Msd, etc. Mine is sold by NX, but any of them will work as far as I know.

I agree with all that as well.

As a former nitrous user safety for the engine is primary. With all that I see you beating some serious cars man. Just be careful and don't abuse of the nitrous( by that I mean using it to many times in a row). Abusing the N2O can damage your even with all those things to make it safer.

Digital MSD window switch might cost a bit more ($150-ish) but it is much easier to deal with when making changes.

That is true ^^ They are easier to work with if you make changes. The cheaper ones use pills with the rpm setting s that can be plugged in and out.
