trying to find the cause of the lazyness in the race car... weve had it shoot fire at night but never in the shop have we been able to see it like this during the day
nope both sides... plugs look normal after a pass
what are these injectors you speak of????Well... there goes my theory.
I'm going over to the throttle body thread and making a new page.
What injectors are you using? What are you using to drive those injectors? Is that driver adjustable by chance? Are they low or high impedance?

as for the cam lobe down. nope... motor was just refreshed and everything was apart
I hope my car blows flames at some point. Anyone seen that happen on a stockish motor with a Vortech, no cats, and mufflers(Flows)?
my car all the time. "flows" being magnaflows and motor is somewhat stockish. Still a 302...I hope my car blows flames at some point. Anyone seen that happen on a stockish motor with a Vortech, no cats, and mufflers(Flows)?
i believe thats would be a "lean pop"my car all the time. "flows" being magnaflows and motor is somewhat stockish. Still a 302...
End of burnout... It's always when I'm at my limiter or shifting at high RPM's
Unfortunately it caused a hole in the bumper last winter as the urethane was cold and 100 miles of a spirited run didn't like it
Such said hole in Bumperi believe thats would be a "lean pop"
Gotcha. I would love to know if that were the case.. but I cut out the factory rev limiter and have a custom tune. I am using my MSD box but I am not bouncing the limiter when I shift....you said it does it when your up near the limiter right? stock computer cuts fuel at the limiter... which is why i believe its a lean pop
Thats what I thought...well then thats not it... the MSD cuts spark
Did you change the cam? As in a different profile? It takes unburned fuel to cause that condition. So somehow there is fuel in the exhaust that is lighting off, or a lot of fuel is not being burned in the combustion chamber but in the exhaust pipe. In other words, the combustion process is still taking place when the exhaust valve opens and all of that combustion process is now finishing itself in the exhaust pipe.haha not sure what the cause of it is honestly... dont think its tune related unless its an issue in the MSD7530 thats causing timing to come out we dont have programmed. but we've put a light on it and the timing drops as it should and shows our base timing while it idles. then the timing drops as the nitrous comes on...
could be cam timing related could be carb related could be fuel pressure on the nitrous side related.
