i've been running a 125 shot of n2o for a while now, and i loved it for about a bottle and a half, but here lately, everytime i spray the motor just boggs down. any ideas? i dont think its low bottle pressure, i just got it filled, but i've heard a few people talk about inline filters, are these necasary, could something be clogged? or do i just need a bottle warmer now that its getting colder?
Thanx in advance.

 

If its cold you won't have the same pressure. It will be low and greatly effect how the well the system works. Try to borrow someone's gauge to see if it happens when the pressure is up. Bottle warmers are worth their weight in gold.

 

Agreed on the bottle heater. I picked one up after I found out that I was only achieving about half of the 150hp shot when it was 55* outside.

There should also be an inline filter. Probably wouldn't hurt to check or replace.

What's up Schultzy?

Does it completely bog and sputter or does it just not feel as potent as it used to?

 

Not as potent... the pressure is not there in the bottle. The heat keeps the pressure up.

mine completely boggs and sputters like its gonna die.

 

are you running a fuel pressure switch? If so, do you have it wired to turn both solenoids off or just the nitrous solenoid?

 

As long at there still is some N2O in the bottle, bottle temperature has a much bigger effect on bottle pressure then how much N2O is in it. Bottle pressure determines how much N2O is sprayed. Below 50* I’d bet that you’re getting maybe 40hp shot of N2O and the normal N2O/fuel mixture is about 6:1 (way rich), so you’re probably about 2:1 A/F with the N2O/fuel that you’re injecting in the engine… of course it bogs.

Filters shouldn’t effect this, but are a very good idea. They’re used to keep crap from getting into the N2O solenoid and sticking it OPEN
