Alky for an 84 hot air?

[racemybuick]

I've seen it done, and I got the basic gist of it, however, I have a couple q's. One is, what is the best possible place for the injection? Ive seen it drilled into the intake adapter, and I havbe also seent he factory ports on the front and rear of the intake, but is there anything better? At the point when I have it on the car and running, how and when is it used? I mean, is it constantly running as the car runs, or only on the strip? Do you shoot it like NOS? Well, that's just the tip of the iceberg for me. Thanks for your help in advance!

Problem is the places to put the jets are in vacuum. So you'll need to have a solenoid to prevent your system from getting siphoned out. I did a kit for a hot air already, its triggered at 3 psi boost. And sprays only when in boost. The more boost, the more it sprays. So its not like NOS.

When you let off, the solenoid shuts. Easy but adds cost to the system due to the extra solenoid, fittings, hoses are longer, etc.. Not bad tho.

what type of jet or how would you mount a jet on a hotair? I would like to hook mine up with both the front and rear vacuum ports. I do have an oil burner nozzle similar to the mcmaster carr M10 nozzle. I found a search from I believe Razor on how to use an elbow for the M10 nozzle but this wouldn't work on the front and rear ports. right?

I was shown a model from Herb Fishman and how he hooked his up was through the adapter to the intake, between the turbo and intake. The jet that came with the kit was fitted through a small hole tapped in the side and the shot went directly after the turbo. I guess it worked damn good for him, so I just need to do what he did. Only, I dont know how he did it exactly. I want to figure the best, most economical way, for the most gain, obviously, but I also want to do it right. Thanks for the help!

I helped with a kit for a Hot Air board member, 6SENSE.

I'll see if he has any pixs to help you guys out.

 

[racemybuick]

thank you razor.

Razor, were you able to find some of those hotair pics?

What kind of system---bought or DIY? If DIY, are willing to remove the intake? If so, there are 3 places you can install Aquamist nozzles. I would not recomend using the 2 factory ports. Aquamist nozzles require a metric tap.

I will be doing it DIY

The intake adapter is not exactly an ideal place to put it. If you've seen pictures/drawings of the inside of the hot air intake, the air goes in to the intake, then moves forward towards the front of the engine, then into the upper plenum area, then into the ports. You're better off mounting the jet in the front of the intake to spray into the open area by the intake ports, that way the alky will actually get into the combustion chambers instead of just puddling in the bottom of the intake. Way more effective.

 

[redhotrod]

I was thinking of spraying either into or close to the existing front and rear ports, one for each side of the motor, I would think that would be the most benificial way to inject.

I suggest tapping into the intake to turbo adaptor for the most simple yet effective install (at least simple as far as our air intake configuration goes). I suppose there could be some differences depending on what is done or not done to the intake (mine is gutted/open plenum Turbomotion V1). However, IMO injecting right after the turbo should prove to promote atomization and equal distribution. Puddling shouldnt be an issue especially with the setup working as it should. As long as the alky is atomizing correctly, shouldnt really matter what intake. Whichever configuration, the now cooler air charge moving through the engine will prove beneficial. Cooler aircharge has always been #1 priority with alky/water injection, especially for a non intercooled car. Fuel enrichment is a secondary yet much much welcomed additional benefit that has especially been realized by the turbobuick community which primarily uses alcohol rather than the more widely used water (tried em all, I recommend straight methanol). Nozzle and psi of course is key here. After much DIY experimenting over the years, I believe the parts I received from Razors kit will/do the trick most efficiently. Im using a single mcmaster m15 nozzle. I have used a NOS fan spray in the past, but I dont think there is any comparison.
I have not maxed out my current combo yet with the little ta33. It is very tempting to jump to a larger turbo but all in good time. I feel that Mid 12s are attainable with what I have now, with traction and a couple more mph (locking tcc should help here), and did I say traction? Larger turbo/more air flow, and turning up the progressive alky a bit should = some interesting #s in the future. I dont consider my car heavily modded at all. Still much to do. The mods I have added are for the most part fairly simple and no different than what any '86/'87 guy would add first. turbo is smaller than the smallest the intercooled guys would go with (ta49), and of course still no intercooler. Plus stock short block and cam. Alky has hands down been the #1 best bang for the buck mod I have done. Finally have (much much thanks to Razor) what I think will be the setup to stick with for quite some time. The progressive capability I believe will prove to be quite the factor. Being able to have as much alky as you need when you need it through a nozzle capable of supplying it from a pump (shurflo) capable of pushing it .....
Depending on future mods, who knows what will change as far as nozzle quantity/placement, but the single m15 should be quite sufficient for awhile. Depends on what your trying to do I guess. If you are primarily trying to supplement (or perhaps replace) fuel then I can see adding numerous nozzles around the intake. Here you may have issues to monitor as far as equal distribution to cylinders. Again, alky/water injection used in the traditional manner mentioned above atomizing correctly shouldnt pose an issue. I can only try to imagine the particulars of his setup and what he has designed it to do, but as far as edging towards more of a fueling aspect, maybe Lee Thompson would have some insight. He, if I remember correctly is using as many nozzles as injectors around the intake and a fuel cell full of methanol. My guess would be their is quite a fuel enrichment benefit going on here
