That whole long-ass drag quad was under 300 lbs, making over 175hp on the nitrous. We never did get a good dyno reading on it. 175 was where the dyno couldn't keep up anymore, based on how fast it made HP on NOS... With the bottle off and closed, it was something like 136, motor only. The nitrous was triggered on the throttle position. If you were 95% on the throttle, you didn't spray. If you WHACKED IT, and went WOT on the gas, you were FULL ON NITROUS, ...
In additions to the turbo(S) - yes, BOTH turbos... Whack it open, spray, and pray that you can hang on...
