DIY Propane Injection

[NickPSI]

I am trying to figure out a way to build my own propane injection system. I know the obvious parts, but what can I use in order for the system to only inject propane at certain times/under certain conditions. IE only at WOT.

Chicken, how does your system work? Kurtis?



Thanks in advance.

I would guess that you would use the same throttle switch from a NOS kit. :eh:
The switch can be mounted on your throttle so it only activates at full throttle.

NOS micro throttle switch part # 741-15640 $11.99 from Jeg's

This requires a microprocessor of some kind. This is the key component in all of the kits and is more or less a trade secret. If you want to assemble the kit yourself you will still have to buy this from one of the propane kit distributors.

$10.95 from Summit part # NOS-15640

No its not throttle regulated it is boost regulated. You need a boost switch which then opens the propane.

sounds like you could make it work off any adjustable pressure switch to me

ya the n20 stuff is just a gas solenoid.....it works the same way that the solenoid for the argon or other shielding gas in a welder works.

This is what I love about this board, all these engineers throwing out ideas to help.


So, adjustable pressure switch, and a n2o solenoid eh....

wont/can't happen. Me and my friends tried so hard ... we bought one of those camping ones and literally covered it with explosive targets and then shot it with a FMJ 30-06 round from about 200 yards out. The targets all blew up but the tank just started shooting out a 3' jet of flame ... was kind of cool but nowhere near as cool as what we wanted. The movies lie a lot ...

I seem to remember my dad setting up a grill tank at 100-150 yards when i was like 10, then his buddy shot at it with his 308 and the tank shot about 8 feet into the air with a ball of flames. He might have been using a tracer round though.....:blush:

or he left the valve open ...

i have seen it happen. they do explode.

i plan to do it this summer :smokin:

it was on real tv once i think. you take the tank, light some fire around it, then shoot it with a high powered rifle. the flame catches the gas that shoots out and hopefully the tank blows :)

they dont blow up good, cause there isnt all that much pressure in a grill tank

take a big gas cylinder with like 2500psi in it and try that :thumbsup:
