can I do port propane injection?

[fluff]

I have a tacoma v6 with eaton SC and want to spray propane. I want to make sure it distributes evenly, do it the right way the first time, so I want port injection. The shape of my SC's discharge manifold wouldn't disperse the fuel very well IMO.

Is propane reliable on a daily driver basis or does it not last very long? Is it's injection rate consistant? Does the injection rate rise with boost? What sets the pro pain kit apart from the others or is there another well founded system?

I appreciate any advise.

I would not recommend port injection for propane.

You will not need to do propane injection with direct port, the propain kit injects gas vapor and it mixes better if you put it in your piping instead.

Injection rate is somewhat consistent with the regulator but injection rate does not raise with boost. You can set it to come on at different PSI levels, though.

It is not a spray!! It is not nitrous.. if I hear the words "spray and propane" used together again I think I'm going to blow up

Well, I guess that excludes me from using propane. I don't want to damage the epoxy coating on my SC, so maybe I'll just juice it. Why is port injection no good? Doesn't mix with the air well enough? Not safe?

I'm trying to find a way to lower my intake temps without the ability to intercool so I can run more boost. Maybe I just need to slap a turbo on and be done with it.

Thanks for the replies.

Do you have data proving that propane eats away the "epoxy coating". I'm not familiar with superchargers.

However you would be injecting after the SC anyway, so exposion to propane is neglectable.

If you want to lower intake temps look into water injection. Propane does not exactly cool intake temps despite various claims (I've measured and saw no difference).

The propane is also extra fuel.. in some case it is alot of fuel and I personally feel it's best if you can tune your gasoline delivery to compensate.

I was under the impression that the propane would lower intake temps signifigantly, allowing for higher boost, like the temp of NOS usually allows you to run more boost if it's a small shot. But maybe I should be looking further into water/alky which can be port injected. I just hear that you have to use the aquamist nozzles and the line that goes to them is not alky resistant, which could cause them to pop off. Any insight on those claims?

Propane for diesels is a whole nother ball of wax.
