Nytro Fuel Injection on Tvector

[Turbo11T]

I have a vector motor in a rev chassis and the way I wanna do the IC is not making it easy to pull the carbs and change the jets. I am thinking it would be slick to run a nytro fuel injection setup.

Couple Questions:

1. Do you think it would work, why or why not?

2. What controller should I use? Boondocker, pl, attitude?

3. How much boost can the stock injectors handle?

I looked into doing this on my rx-1 a few years back. I was going to put an apex head on it and everything and I was told that it isn't doable. Something about the heads are different and you can't put an apex head on an rx-1 bottom end. I was told that the stock head wouldn't respond well to the fuel injection.

i disscuss this befor with a yammi guy said it could be done .need all the nytro electronics + fuel rail the vec uses less fuel so you would need a controller whatever you can get for a good price. mite have to have it reprogramed not sure how much fuel you would have to take away nms system would be the best.the only thing you would have to look into is whether the intake ports are the same angle on the nytro vs the vec mite need the nytro head.

I like NM's fuel system and I think it could maybe even be made to work well with the carbs, but I really don't have room for that either. The injector boss's would have my steering post. I can pull the carbs easily without the steering post in the way. I had a friend sugest making a three pc post that I can unbolt the center section to get the ic off.

Still thinking fuel injection would be nice. But don't want the headaches of not being able to pull fuel back enough either.

just hold your horses.. as soon as it snows I might have a nice alternative for ya.... If it works as well under load as it did in the garage.. forget gas.

I think you could get away with a boost signal restrictor to your carbs. You just jet a bit fat with your mains and then install a valve in the signal line to your carbs so you can restrict the amount of boost the carbs see. I have a buddy that did it on his Vector/Rev sled, and it seems to work. If I remember correctly, he used the carb coolant valve from the stock 800 carbs.

Believe it or not I have a coolant valve sitting in my garage on the bench.

Perfect! Come to think of it, I am sure Phil is running stock mains. In theory, pressuring the bowls provides enough fuel at wide open. By restricting boost to the bowls, you drop fuel pressure and fuel supply (leans it out). Try it out and let us know how it goes!

I know on my setup, stock jetting was to big as my pitot tube got a crazy amount of pressure to the float bowls..

you should be able to get darn close after a few runs on jetting, then you can just adjust appropriately with your valve in the air stream, this worked really well on mine, and im betting you will like it as well, then you can keep everything together and keep your current airbox/ic setup.

Much the same way a variflow works, in a manual sense or dpm in a automatic sense. Changes the float bowl pressure, allowing less fuel at different alltitudes.

its exactly what it does.. beautiful stuff.. carbs are pretty nice in the simplicity, you just gotta figure out how to make em work for ya.
