I have a tnt F2 kit and I decided to go and step it up and go to the 200 jets my air fuel was at 10.00 %on the wideband what is the right air fuel to get the maxium H.P.

 

Under 12 is what most recommend.

So say 11.5-11.8

I am planning on 11.7 when I spray 200.

 

this is a wet kit too.

 

Does the wideband max out at 10.0? Many do. You may even be richer than that if its maxed.

Anyways...for a setup like yours I would shoot for 11.0-11.3 or so. I would also be inclined to run some 100 octane.

Di you do this on a dyno. What gains did you get?
And whats your timing?

 

 

good avice right there

 

did a 150 shot on the dyno and was reading 11.5 and produce and extra 152 h.p on the dyno compared to my all motor run. I dont know the exact timming I have out of it my buddy tunned it I will have to ask him.
