May need a 6.8-6.9 to get there. A 7.0 in the 1/8th got me an 11.17 (damn wind resistance)

NIce!! When you throwin a cam in there??

 

Congrats on the new times!!!

 

nice runs, so you are not adding any extra fuel for the nitrous? I think I would be scared of melting a piston

 

Nice time!!
He is adding more fuel with the nitrous,just running a leaner A/F than most do like on motor.
Even though he may run the same A/F on the bottle as motor,that does not mean he is not adding fuel,you have to add fuel with nitrous or it will go WAY lean.

 

I am running a custom dry kit from nitro dave and I run 1.20 on the pe multiplier on motor and 1.22 on the nitrous and its the same afr so adding fuel just not like most people say you shoud run 11.8 afr on nitrous i am running right around 12.6 to 12.8 no knock and running 22 degrees of timing and 32 degrees on motor.

 

dang that's alot of timing on motor.

 

thats what i was thinking. i only run 26

 

Congrats on the new time. Interesting fueling. I'd be pulling spark plugs after every pass.

 

"The mixture is read at the very base of the porcelain and if you can see a ring of color with your naked eye, you are DEAD RICH. The base of the porcelain should be a clean white and if there is color there, it should take a magnifying plug light to see it and it should be very faint. At this point, you will be somewhat close. Dark specs is usually detonation and the fact that you described your straps as a "grey color" sounds to me like you have too much lead in the motor. If the strap or end of the plug looks like it has been hot, such as this "grey color" you describe, it is generally over timed. If the gaps open after a run or the sharp edges are no longer sharp, you are over timed. Depending on the plug you run, there will be no "heat line" on the strap. If you run NGKs (and you should) and see a "heat line", you are over timed. The proper tune will deliver a plug that is scary clean on the porcelain and a strap that takes on a little of a dusty cinnamon color on the strap...."
