At present, I'm working up on the amount of rpm this system is going to give me with the TC I'm now using.
I am using an extraordinarily tight TC. Off the nitrous, and at zero boost, the TC stalls at 2400-2700 rpm.
I'm presently up to about .92 of a second on the nitrous before the transbrake is released for the launch. The rpm by that point is 4090 rpm with the MAP maintaining a very steady climb. The turbo I'm using is very big. Even for a V8 it would be considered big. An Airwerks S510/91mm. The turbine side looks to be for a diesel truck. At launch, only about 1 to 1.5 psi boost has developed, but the MAP from nitrous activation onward maintains a very steady climb.
The car actually leaves the line more as a nitrous car and transitions to a turbo only car by the 70-80 foot mark.
To answer your stall question, the tight stall of the TC is presently acting as my rev limiter for the launch.
I am going to slowly work up with the nitrous on-time before transbrake release to see what's on the other side. Stay tuned.
