Fuel jet/N20 jet Sizing

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.

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.
 
NOS has released most of there there new baseline Tune ups.
If you go to NOS site click products, then click whichever kit you want then look at instructions the tune ups are there.

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.
 
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.
