depends on fuel pressure.

depends on fuel pressure.

I'm not looking for FP setting, just what ppl are using # wise on their jets....
I'm going to assume most nitrous ppl will set it around 5.5-5.75.

Perfect example!!!! Is that like a 550 shot slighty lean?!

 

[johnquick302]

Perfect example!!!!

im just talking shit, i never used that before. it would burn down id think pretty fast with that tune up. but it would be fun for a few seconds.

Well. that changes the jet spread.


If your looking for good baseline tuneups. call monty smith or steve johnon. Both guy are very good at delivering clean tuneups that don't kill parts.

I belive Monty Smith had alot to do with those new tuneups.If so thats a good thing. He tunes some of the fastest Nitrous motors around.

 

[82bird]

Yeah I was wondering why all the tune ups and that big sheet of timing numbers for the big shot where all changed. Its a good change tho, especially the timing chart

At stage IV jetting level (93/93 jetting), the Cheater nitrous solenoid is flowing at maximum capability. Increasing jetting levels
beyond this point will not provide a performance increase. If you need performance greater than Stage IV delivers, contact NOS
Technical Support for information on higher flow rate solenoids and other related parts.
