I got 3 full passes on a 150 shot before the pressure would start to drop drastically.

I got 6 full passes out of a 15# bottle, and then the car started to slow down quite a bit.

That was in a 10 second mustang with a 150 jetted NX plate.

 

its normal, this is what I get evrytime...not long enough. I wish I could spray 100x more..

 

It sucks....but hell ive got too much time and money in my kit and havnt used it enought to pull it for F/I, maybe next year

 

ha ha! i wish i got 3 passes out of a bottle. i have to swap bottles cause i can make another full pass, lol!!! it is impossible to maintain the pressure throughout a full pass. that is why i have 7 bottles and a mother bottle for topping it up.

and yes i am an addict!
