I just read the link. Hmmmm, thirty seconds for 90 bucks, the chargers can be had for about $12 a case of twenty from commercial food supply stores, whipped cream makers.
How is the extra fuel supply happening? Hmmmm.
I like the post about the engine "sneezing parts all over the lake", LOL
I can picture that!

I think with a couple "whip-ettes" and some home-depot type hardware one could rig up something cheaper than 90 bucks,
the trick is to get it to fire at MAX throttle, which is what NOS Systems instructions say, only at max.

They said most engine failures come from the system being 'on' (or leaky seals in the valves) at first ingnition.
A build up of gas and/or n.o.s. at first ignition and KABLEWIE!!!!
