I personally am not impressed at all with nitrous cars regardless of the e.t. I know there is a real science to making a good sytem work and the motors have to be built completely differant than a N/A motor, but they usually don't run what I think they should for the "advantage" they should seem to have and that eveyone who uses them claims. But the same holds true for all the "big" engines I run against. I've worked a long time getting my little engine to run like I think/know it should and I'm not done with it yet. 8.92 149.95 m.p.h under 370 inches 2950 lbs N/A
