Funny Gas Facts for LTx!

[Stroked96Bowtie]

Hello LTx Tech!

I took some time to gather and format some pretty common stuff about nitrous. The idea is to help kick-off the nitrous section of LTxTech with some helpful LTx nitrous detail. Im sure others will add, and please do we can create a master sticky with all the good on nitros setups for our cars.

NX, TNT, Zex Jet Sizes (Wet kits)
Single Nozzle (RWHP Rated)
50HP = 35N 10F
75HP = 41N 22F
100HP = 52N 28F
150HP = 62N 33F

Dual Nozzle (RWHP Rated)
100HP = 35N 22F
150HP = 42N 25F
200HP = 51N 28F
250HP = 55N 31F
300HP = 63N 35F
350HP = 67N 39F

NOS (Wet)
Single Nozzle (RWHP Rated)
75HP = 41N 28F
100HP = 51N 31F
125HP = 55N 35F

NOS (Dry)
75HP = 28N

looks good.....and I really like those wiring diagrams ;)

One thing I don't understand is why so many people still feel that a projected tip plug like a TR6 is safe for nitrous. I know a lot of people are using them but they must look like a glow plug :shame:

There is a big support for those plugs with a power adder...I still use the stock heat range TR55's (@.035 gap) for the little shot Im running. Seems to work good so far.

What other plugs are good for nitrous?

Nice info, thanks man :)

I was looking to get some thing like that for here. They were writen by others and I had not got approval from the writers ;)

As long as all is in order it will stay stuck :D
