Does anyone have any real experience with an alky setup in a daily driven TD?

I have a GLH I'm building up for street fun and my original plan was to put a big intercooler in it to feed my freshly built 2.5. The more I try, the more sick of the idea of a large cooler I get. I tried with a Porsche 944 cooler, but it just isn't working.

I am fully willing to put out the bucks for the alkycontrol.com setup, but I am wondering how far alcohol injection can take me with no IC. I am planning on using the stock garrett, or stock garrett with a bigger turbine housing. Will alcohol alone support ~20psi on pump gas while still keeping EGT's reasonable on the street? And maybe ~25psi at the track when I go?

I know a lot will be individual-setup and tuning dependent, but just to ballpark here so that I'm not stuck going down a path that was a horrible idea to begin with. Someone give me some input! Keeping in mind this will be a daily or often driven street ride.

Thanks,

My thoughts have been that chemical intercooling was only to be used as a supplement to standard intercooling. Why can't you use a GLHS intercooler setup?

I think that having an alky system would work if you got it just right, BUT you'd have to be very very careful to look out for (alky) system problems while cruising around at 20 - 25. Does that sytem have some sort of low fluid alert? I know that's something that you could monitor yourself, but the situation could be catastrophic if it did happen.

Also, you'd HAVE to get the mist distribution just right. individual runner nozzles may work, but if you just put a mister before the throttle body; i'd put money down that cylinder 4 wouldn't be around for very long.

all of this is my personal opinion, and I don't don't think it should be done without an intercooler.

You have some good points. Yes, it does have an LED for low fluid level. Also, I was thinking I may wire it such that in addition to just lighting the LED, it would also flip a solenoid which would somply route full manifold pressure to the wastegate.

I was planning on only doing the single mister before the throttle body. I am in the process of completing the "#4 cooling mod" for what it's worth. (Seperate line from water pump to side of head next to #4)

The reason I wasn't going to use the GLHS IC setup is because of lack of flow in the stock unit. If I can get 20psi on the street, I'd probably be content there. I just don't want to plumb some huge cooler in an omni if I can avoid it.

Other opinions? Honestly I figured after the emergence of Larry's 500+ HP alky fed motor there would be more interest for chem injection in a hurry...

A properly set up alcohol injection system can out cool or cool as well as any IC out there period. Plus heat soak is no longer a issue, the need for race gas has been eliminated. You have around 105+ octane depending on your mixture your using.

I run the "coolingmist" system my daytona. I was at 22# of boost with garret t2 with the system comming on at a 15# works great! I bought the basic kit $139 us 3.5 gph misting nozzle. I will be going to two nozzles the 3.5 coming on at 10# and another 3.5 gph on at 18# We'll see what happends

Cracked:
So you don't use a progressive setup? The one I was looking at will up alky per psi of boost, that way you don't need a second nozzle coming on for higher boost.

Now my question is whether or not to try something crazy like a multi-port setup so #4 doesn't lean out.

Thanks for the input gentlemen.

zerolag, i have my egt gauge in the #4 runner, every thing looks good!! Ive pulled the spark plugs and they all match I have looked at the progressive set up and will definatly go that route. I can then have it come on earlier(5#) and then ramp up (water psi/ boost psi). 22# More power

A multi-port setup that is "progressive" is by far the "best" way to go for the most ideal setup. That said, you probably don't need to go that exotic to be safe & reliable. Cracked's 2 stage setup would work fine for a non I/C street car. (although in your case with, with no I/C, I would run bigger alcohol injectors and less gas) With no I/C, I'd probably go with 5 gal/hr nozzle opening at 7-8psi, and a 10 gal/hr opening at 14-15psi. You'd have to watch your EGT gage, and run the boost up slowely, to make sure you're safe. With a setup like this you could definately go 20psi on the street, once you dialed in the correct size of both alky nozzles.

I've got the coolingmist setup... 100psi pump with (1) 15 gal/hr nozzle. (single stage) It opens up at 13psi. I've found that most of the time I don't exceed 10psi under acceleration. If I do it's because I've got my foot to the floor. lol I do have a large Volvo FMIC though. I'm definately on the "rich" side, but until I get my EGT gage hooked up, I'm not going over 16psi. I figure my EG Temps right now are probably in the 900 - 1000 degree range (brrr) due to the amount of alky its drinking at a paltry 16psi. I'll probably tune for around 20psi, like you, once I get the EGT gage hooked up.
BTW... this is my daily driver. (45miles round trip to work)

Honestly, bang for the buck, alcohol is probably the cheapest power adder going. As most will echo on here, for $200 - $300 you can have the whole setup, and by just adjusting jet size and boost, well... God help your drivetrain! lol

Hoped this helped.

PS- I would never be without alky on a turbo vehicle again. If I buy more in the future, this would be one of the first mods I did.

Do you guys have links to good alky set-ups, or are they already up on a million threads in this section already

?

Already up, do a search... Coolingmist... Alkycontrol....

Did you check out the kit that Dvldoc has posted in the progressive alky kit group buy in this section. I've priced out a few of the other kits out there and his prices blow them all out of the water. Looks and sounds like a very nice unit. I ordered mine Wednesday and it's shipping Monday.

log non IC setup is best for the alki. A buddy here adds a grainger and a Hobbs switch to his grand national. Fills the washer bottle with alki, hooks the hose into the intake pointing really close to the compressor of the turbo. Run the hobbs switch to washer bottle pump, they are preset for 15 PSI, perfect. Then run 20 PSI of boost. Around town no alki till you floor it and hit real boost. The nice thing about it is the compressor really does a nice job of atomising the alki so it cools and fires better. Very simple mod for a GLH T1 car.

I am running 32 lbs of boost on 91 oct. Meth comes on at 10psi. My piece of crap turbo broke but have no signs of damage to engine from detonation. Drove this way daily for 3 or 4 weeks.

Where can you get Methanol? This is probably a dumb question...

I also race a 360 sprint car that runs on methanol so I always have plenty. I buy my barrels from a guy at the racetrack. 100$ for a 55 gal drum.

Use caution when handling methanol. Wear rubber gloves and don't breath the fumes. It can damage internal organs, and the nervous system.

Use it in a well ventilated place.

If your local speed shop doesn't sell it, then they should be able to point you at somebody who does. If there are alot of guys racing circle track in your area then it should be easy to find. I buy Edge racing alcohol (which is marketed by the people that sell Turbo Blue race gas) at a local gas station for $1.89/gal.
