Don't get your hopes up for use of this system on the older Vipers. They don't utilize "Top Feed" injectors. But, the new 2003 Vipers will have top feed injectors and the system is available for V/10 applications.

I have also seen this new setup and while It may be neat on some applications, It is not the safest method of injecting a nitrous/fuel mix into an engine.

Remember that a direct port style nitrous injection system has no method of controlling nitrous or fuel flow into the engine should a solenoid fail in the open position. At least with nozzles outside of the throttle bodies you are protected by closing the butterfly of the throttle body allowing the nitrous/fuel mix to escape to atmosphere through the air intake, should a solenoid failure occur.

Just my $.02

What's a top feed injector?

Top feed injectors are supplied fuel via a "Top mounted fuel rail" isolating the intake from the fuel.

ALL current production Vipers utilize "Galley feed" (also known as) "Bottom feed" or "Side feed" injectors. I'm pleased to see Dodge's Gen III production engines now produced with top feed application injectors.

If you take a look at these pix you'll note our conversion of "Top feed" injector rails in contrast to the preexisting "Galley feed" system. The fuel rails mounted atop of the injectors supplies a cooler dose of raw fuel translating into a much denser fuel/air mixture. High performance applications need higher demands in fuel supply, the rails (especially larger ones) supply a larger quantity of fuel, dampening injector pulses and assure against fuel cavitation. Also, there's a much better selection of top feed injectors readily available in today's market to facilitate our performance modification upgrades. Not to mention, the cost is less of these injectors. As a side note, a larger injector cannot suffice for proper fuel distribution unless a properly programed ECU has been retrofitted.

I agree with your explanation, but of course, their are several ways to safeguard against accidental discharge of nitrous. As we all know, nothing is ever "Fail safe," especially with the use of nitrous but there are as many cars running around with "Plate systems" or "Direct port" applications as there are "Pre throttle body systems." Commonly, you'll find it much easier and cost effective to install a "Pre throttle body" system on the "average" road/track nitrous system.

"IF" this new system proves to be successful (for it's intended purpose), you'll see these become a VERY popular and effective means for nitrous enthusiasts. Once again, I can see it as one of the MOST innovative products to hit the nitrous industry!

Best,
Doug
