also running NOS after the blower would be hard to tune i believe, since there are such different intake temps with the JRSC due to heatsoak occuring by driving hard for long amounts of time.

If the air is pressurized at 6psi, and the manifold is still cool, when u would shoot the NOS in, it would cool the intake charge to a certain extent creating colder denser air which needs additional fuel compared to the standard percentage mix of N20 to Fuel that is added. Now if the manifold is hot, there are hotter intake temps going in, and when I'd spray the n2o in it would change the intake charge temperature a certain amount, but not the same amount as it would compared to if there had been no heatsoak, so i cant predict how much extra fuel to add for the cooling effect.

That is what's causing me quite a conundrum here....
trying to get perfect balance of N20 and Fuel added, and where to mount the injection, and also another problem would be about what to set the timing at.
