After doing some research I saw that with NOS you want your A/F to be around 11.5-12.0. My A/F N/A was 12.8-13.0 and they told me my air fuel was identical on the NOS compared to N/A and it was fine? Is it dangerous to run it on spray at those A/F ratios? Im running a NX wet kit with 52/33 Jets.

Thats a bit lean. I spoke to tnt about safe afrs. They like to see 10.9-11.5. I say look at your fuel system.

 

I would shoot for 11.0-11.5 on the spray at least put a 34 and redyno it.

 

Is there a chance more power can be made if my A/F is better? Im not sure if I was loosing anything by being soo lean on the spray.

 

Just save for a new motor...

u may pick up some tq with the right af.

10hp is not worth the cost of a new motor IMO.
