looking for the formula
well, i can say this much....
someone i know accidently put his window switch for 2000 instead of 3000 and sprayed a 135 wet shot from a nossle in the bellow... HUGE backfire and cracked his intake.
this was on a proven, sprayed it 30+ bottles nitrous car...
based only on that, id say, 2000 is a little low for a 150 wet shot..lol.

In the stock LS1 I referenced, (from a good engine simulation program) average intake port velocity was about 80 feet per second (fps) @ 2000 and increased linearly with rpm. (160 fps @4000 and 240 fps @ 6000).
Intake flow (CFM) is not linear with rpm as you might expect, but it's fairly close. If a "150" shot injects the same amount of nitrous and fuel independent of rpm, it could easily be too much for a slow rev from 2000. In first gear engine speed is increasing over 1000 rpm/sec.

it's just one of those debates that will never be solved.

now 3rd (auto) or 4th (manual) might be a problem. good thing about autos is they will downshift.
