any hot airs on alky?

This sounds exactly like I have mine setup. It's good to know others have tried it over long periods with no damage to turbo. I will continue to use it this way with fewer worries, hehe.

What group purchase? how much is the $355 kit with the group purchase?

lemme know..

also.. someone tell me why a hotair motor sucks alky in and a IC motor wont..

I think the vacuum must be stronger after the turbo, say at the adapter, since the same VOLUME of air is moving through, but the pipe is smaller, resulting in a higher velocity, and more VACUUM. Our bigger 3" intake pipes move the same VOLUME, but since it is larger, it is at a much slower rate, hence no problems with siphoning that you run into when connecting at the adapter.

Don't know if there's anything to this, but just my opinion. Let me know if anyone agrees.

I think if you went to the intake manifold on an IC car (which is essentially what you are doing at the adapter of a hotair car), you would see the same result. That's why noone needs a check valve on IC cars, since they go to the larger intake pipe (before the TB).

it doesnt seem like the velocity would be very high until you get into boost.. hell... max flow of the turbo is only 390cfm.. but.. i see what youre trying to say...

has anyone screwed a nozzle into the side of the turbo? i really would like to install this kit (whenever i get it) without taking the turbo off..

The reason is simple. On the IC cars the alky is injected in the IC plumbing BEFORE the throttlebody. There is little to no vacuum in the intake tract before the TB.

If you inject it after the throttlebody like in the adaptor you've got 17" of vacuum sucking the reservior dry. The only way to do it without a solenoid is to inject it into the MAF pipe since there's no vacuum there.

Alky

I have been ironing out a homemade alky system since last fall.
I believe I have it working pretty good as of the Bristol event.
You can run a nozzle pre turbo, IF YOU USE A NOZZLE THAT ATOMIZES. I am using a .020 pre turbo atomize jet, coming on at 5 psi, a .024 non atomize ( nitrous rooster tail fan pattern nozzle) coming on at 15 psi. I drilled and tapped the intake just below the cone adapter for the second nozzle. I tried a .044 nitrous spray nozzle in the intake but if I didn/t launch with enough RPM the car would stumble. With the pre turbo nozzle,also coming on at two different power levels, I was able to get rid of the stumble.

This calls for 2 hobbs switches, 2 nitrous solenoid valves ( they must be alky compatable )

I am using methanol. I tried windshield washer pumps with some success, but have went to a Sure Flow pump to get enough pressure to atomize. Jury is still out on this pump.
