Hey, for a low power Nos system that self regulates according to the power requirement of the engine, would it be reasonable to run the Nos itself thru an extra fuel injector that runs in parallel to the original injectors (ie. so that metering is regulated just like the fuel thru the injectors - ie. according to actual engine demand) - and use a system of increasing fuel pressure for the fuel enrichment part - ie. I was thinking maybe of a setup where the Nos itself is used increase fuel regulator pressure when the system is activated.

The system would be designed to operate only at WOT (microswitch on throttle) - but thru the whole rev range. How about taking the fuel regulator vacuum from a fitting attached right behind the TB - and the Nos injector actually fires into that reg vacuum line (Tee'd in) - with a restrictor of the right calibration in the fitting behind the TB such that there's a pressurizing effect on the reg which is the correct relationship to the Nos output to make it all correct.

How does that sound?

That is exactly the way the Kit goes together, when installin the DRY Kit. No need for an extra injector with a dry kit. Check my post in relation to BA on NOS. It is pretty much self explanatary. To adjust the amount of NOS the engine ingests you change the jets in the NOS injector. As to using it through the whole rev range, i currently do when at the track. Simply ARM the NOS, Turn on the Bottle, and when the light goes green, floor it and leave it in Drive with the Econ switch on. Thats it.
