I'm wondering what induction your using(carbs or Enderle hat)?

What kinda N2O system(Plate on top of huffer or Fogger)?

I ask because if you are using a plate kit on top of a huffer, it really messes with the fuel/air supension when it get pushed around the lobes and all, Fuel has alot of time to fall outta supension(I perfer a Fogger setup in the intake runners just north of the port nozzles.

If you are using a injection hat instead of carbs, well the benifit of the hat is a scopping effect, draw back is, the air collects to the rear of the engine.

Just throwing out some stuff to get you thinking more about your combo. It sounds like your going lean on the 2 cylinders.


Ohh yeah, on boosted aplication made you should use a ignition box that retards timing in relation to boost like the MSD 6 BTM
and then use a fixed retard box that will pull a fixed amount of timing the instant the Spray is activated.
pull 2 degrees per 50hp of Juice... and then a additional 2 degrees of a safty margin.

150hp = 8degrees of retard for the nitrous alone...

Hope some of this helped.
