I thought about spraying my car a couple years ago and decided not to. I talked to one guy who ran nitrous and he told me it was addictive and I would not let it be at a 150 shot. Instead I put on alky for a while the had to park it until last year. Switched over to E85 when I got the car back out only ran 4 or 5 times last year and health problems forced me to park it again. I have raced once this year and the car ran great but, now I have very low oil PSI. I have not torn it down yet maybe after vacation in a couple weeks I can look at the motor.
