Default First time using spray

I won a $500 gift cert at a local speed shop, guess what I used it for?
NOS EFI Wet system!

Can it run with a stock Fuel Pump, and what else is a must?
What about the heat in the back with the bottle? Will the Vent Shade provide enough cover?

How much hp are you shooting for? Your bottle getting warm in back is a good thing. Keeps pressure up.

I will probably spray 75-100 shot. I am worried about during daily driving and the sun beating on the bottle even though I have really dark tints. I wonder if the vent shade will work to keep the heat off, or if I need a blanket.

Heat is a good thing. For it to get too hot, well...I don't think that's gonna get that hot, but one thing I do have on mine is a blow off tube.

Basically, if the bottle pressure gets too high, it blows a seal on the bottle and vents it down and outside the car. Safety helps a bit there.

south florida heat is bad! my bottle buried the needle at 1500! i was wondering why the safety didn't blow!!! the pressure was so high the purge selonoid wouldn't work. that evening when things cooled down, it seemed to operate ok.

for they guy wanting to jet it 150... i've been told the car's computer can safely adjust fuel, timing etc. up to around 100hp. after that you should consider aftermarket ignition, colder spark plugs, better fuel delivery etc.
not worth the risk for me 100 shot is just fine, i usually beat everyone without having to open the bottle anyway!
