So I went back to the track for more yesterday, drove 50 min to get there and while prep. the car I open the nitrous bottle and nothing... Empty or auto opener failure? I just re filled the bottle so the mechanic must have left it open.

Anyways, since I was there I did 4 passes on motor alone and got my best motor run at 14.75 at 94 mph. I'm so frustrated at the fact that there are no more performance parts to get under $900. I think I bought them all! Is this it? Cams, headers or a custom project? A engine transplant may be cheaper then keep going.
ps. No I don't want another car.
