Converting secondary injectors to Nitrous jets?
« on: December 10, 2019, 08:07:02 PM »
I have an RCC Ultra turbo manifold but will not be using the secondary injectors - just bigger primaries. I was thinking that the secondary fuel rail would be a good place for nitrous jets IF there was some sort of adaptor that could fit in the injector holes to hold the jets. Does something like that exist? I suppose I could machine something to do it but would rather buy a proven product.

Does anyone know of an adaptor like this?

Thanks
Don

Don, I think Nitrous direct has a nozzle that shares space with an EFI injector... but I have not seen a replacement.  Of course you could use one of those and plug the injector or install a dummy

Thanks Stainless, I checked it out and think I found what you described. However that adaptor is too bulky to fit in the plenum recess hole. I will keep looking. Or just buy a throttle body holder with nitrous injectors like Schnitz sells.

Yes I plan on running nitrous with turbo. Even though I have an ice bath intercooler I still think the intake temps are too high which contributes to my exploding engines.

The nitrous will add cooling too, so the plan is to reduce boost a bit and make up the HP with Nitrous. That's the theory! I am going to use a MAXX ECU which they say will handle the fueling well and have safeguards as the system will have closed loop, traction control, boost control, etc.

I did make the nitrous injectors to fit in the plenum and when I am finished I will post some pics here.

Great love to see it. The diesel guys use nitrous with turbos so why not?

The injector replacements are all finished and installed. I was lucky that I already had a piece of Al 1" rod laying by my lathe. I used that to make the 4 NO2 injectors. I tried to match the profile of the existing fuel injectors but the most important part was to get the o-ring seal correct. BTW, had to use my 20 ton press to get the old injectors OUT of the plenum. They are a very close fit in the plenum and after about 6 trips to the salt flats, had enough salt galvanic corrosion that they had welded themselves in. So I think I wrecked them trying to get them out.

Once the profile was shaped on the lathe I polished them, cleaned, then set up an anodizing station to anodize them for anti-corrosion and dying. They came out a little darker than I wanted.

Then I put the old o-rings on, bolted on the fuel rail and all appears to be a good fit. I will run two -3 braided NO2 lines from a solenoid (had to buy -6 to -3 reducers).

So that is how I will use NO2 to give me a bit of power, and cooling. Yes I could have bought a kit to do this from Schnitz or somewhere else, but if it is worth doing, it is worth over-doing.

Awesome work I'm curious of how much heat it will pull out of boosted air.
Here's how they do it in the truck world, don't need no fancy airbox.

Damn! Why didn't I think of that! That is so easy. Those diesel truck guys are geniuses! Awesome!

Actually I was thinking of something similar to get a few MPH more.  Pulse-jet exhaust pipes!

If you landspeed turbo guys weren't so adamant about blocking off your air intakes you could have scramjet power at speed lol

Oh i agree , Last bodywork we had done at Airtech spent a fair bit of time making ducting from the front to the turbo and including it in the fairing

Looking good Don,   :thumb:
