THE BIG PROBLEMS IGNITION LEAD
PULL MORE TIMING OUT AND ADD A LIL FUEL
AFTER 16 YEARS OF PROMOD/PROCOMP YOU'LL FIND OUT SHIT
I agree 100% this will eliminate "abnormal combustion", pre ignition, detnation. As a byproduct of doing it this way you lose lots of power. It doesn't make sense to spray 150hp of nitrous into a motor that only makes 195 hp because you have too much timing backed out of it, and loading it with too much fuel. 195+150 yeilds you 345
This has been my arument with big wet kits for years. Subtract another 10 motor hp for the pertruding nozzles. now you have a 335hp motor
Nitrous is a balancing act, The most timing you can keep in, the least amount of fuel, and the hottest spark makes the most power every time. You just have to figure out what works and what burns parts. Last year our motor made 253, and we hit it with 150+ dry nitrous pulling out minimal timing, and adding probably too much fuel. This combination made 400+hp with the back tire breaking lose.
There is a lot more to be made. Control is the issue
