Pure N2O was Re: Siamesed ....

[Dave Zug]

You're  thinking Steven!

How many folks read that and had that little light just burn out in the
brain   lol...

What kind of N2O flow would be required for that to happen... hmmm... could
I seal off my TB and try this???

MAP would be bad for this, as you'd never reach zero vacuum..(or could you
just re-VE for 0 - 40 Kpa). MAF would have to be placed AFTER the N2O
injection, and N2O would be the only thing flowing.. at 1/4 the normal
rate??

need a 2-way ball valve for the NOS or maybe hook the injector drivers to
the NOS solenoid and pulse it (isolation setup required of coarse).. with
the proper N20 jetting... hmmm.. intereating!
