I got 1.2 sec and 13 mph (on a 12 second car) on a 0.051 jet

Something may have been up...


Superchuck, in my limited experience, that sounds like a good start. WHat fuel jet and fuel pressure you plan on running?


The carb is using 72/78 I can't remember the nitrous jet sizes, the kit came with 100/ 150/ 175/ 250 jets. I put in the smallest. Carb fuel pressure is 5 1/2 and I still have the set the pressure for the nitrous, I was thinking the same at 5 1/2. Maybe I should tighten up the spark plug gap?

My car is only used for sportman bracket racing, I'll only use the nitrous for test and tune for a few of those WOOHOOO passes. I already had the kit for something else.
