I do need to video tape the car off the line and down the track. Well I guess this car is defying the laws of physics, or is it? Here is an experiment for you. Hook you garden hose (10 psi of fluid?) against your air compressor (125 psi air?) I bet you'll fill your air compressor tank up with water in a matter of minutes. Fluid pressure will win every time no matter what the air pressure is.

On the Nitrous injector. Which I made myself, I inject the NOS in behind the fuel to force it into the intake. 10 psi of boost is not going to hold back 7 psi of fuel.

ok thanks. i got a t25 turbo so all i should need is a electric full pump that will run round 10psi and a new fule line then all that is left to do is to make a custom hat to go ontop of the carby and ehaust manifold. then tune it.

I think you got that wrong son.
Thats like saying 1 tonne of bricks is heavier that 1 tonne of feathers.
Pressure is Pressure.
My bet is a look at your plugs after a dyno run, will show white hot plugs.

Boost pressure wont affect a brake booster "IF" it has a one way valve.

Some water might enter the reciver tank of the compressor IF the joint where the air and the air hoses were joined was higher than the compressor.

Hey Bart,
Did you give the experiment a try? I'm sure you have a drain hole on the bottom of your air compressor tank to remove the water after the experiment is done.

I think Phunkdoktaspok ought to do it as well.
And we are not talking about 1 way valves.
My plugs are fine and I'm using a MSD Street Fire Ignition Box as well.

Come on, give it a try.

If you want me to explain why a higher air pressure is no match in pushing a lower fluid pressure than let me know.

I'm not going to try your experiment. The compressor would blow my hose fittings off at the garden tap. Plus you realise the pressure at the tap would be higher than you might think.
I reaalise that fluids are non compressable. but if you have an explaination, please enlighten me. I'm not saying your full of sh1t, I'm just saying what you say goes against what I've read. Doesn't mean you are wrong. I'm all ears mate.

As you are right, fluids are not compressible but... they are but a minimal amount. So minimal it is not even calculated. Anyways, compressed air will not push back a fluid but only push by it. One to one side of the hose and one to the other. 125 psi of compressed air going one direction and 10 psi (or what ever your water tap puts out) going the other direction. You will fill your air compressor tank with water and if you concerned about your water lines, use a air pressure regulator to decrease the air pressure if you are willing to still try it.
Really, don't try it.
If there is some type of baffle between the two than yes, of course, the high pressure will prevail.

Have fun and I hope to back on the road by later next week. No more broken axles..... I hope.

1 way valves is refering to the post about brake boosters, as it states.
But since you refer to it now, 1 way valve. What is a needle and seat in a carbie?
If your 1-12.5 fuel/air pressure ratio can over come this. Well I guess I'd like to see that and learn your secret.
Should be good to hear your description on how the needle and seat will drop as the fuel bowl empties.
You beaut ignition wont do anything to stop plugs burning white hot if the mixture is lean as a result of the fuel bowl not filling up.
Do my experiment of checking your plugs after a dyno run.
Take it easy.
