www.alcohol-injection.com or type in Devil's Own in google. Also, they are a supporting vendor too I believe. Boost based kit works great for me and my 2.6" pulley. Blower stays just warm to the touch and not crazy hot.

I'm posting this from a different thread. It was posted by 2K5SS/SC
I'm going to dable in on this one. Here is my take on things as I have seen and proved it myself.
1. Better traction, a better clutch, and DSS Stg2 axles = a broken 3rd gear for me at the track. I wasn't running slicks and all I had was and Ingalls TD for wheel hop, but when I pushed the clutch in and put it in third gear exploded without a hop, grind, or anything! Be cognisent of this as I am on tranny #3 already and they get expensive.
2. As for the HE adding HP, I'll go 50/50 on this. For all intents and purposes, a car receiving colder denser air into the combustion chambers will effectively make more power because a better burn will occur. From this we can conclude that the HE allows the air entering the combustion chambers to be colder effectively gaining horsepower from it. Also, it can be known that the blower will not heatsoak as badly and recover faster from it with the HE preventing the loss of HP due to the hot air entering the combustion chamber. I have seen turbo cars gain up to 60whp with the addition of a more efficient intercooler and no tuning, thus prooving both points here.
3. With methanol injection, I spray before the blower and can confirm that it makes my blower a lot colder considering I have a 2.6" pulley right now. After a bunch of consecutive pulls I did, I pulled over and placed my hand on the blower. Without the methanol, it would have burned my hand, but with my methanol I could touch it and it was nice and cool. Now methanol will effectively add more power without tuning by adding higher octane into the combustion chamber and cooling the air charge at the same time. Colder denser air and higher octane would definitely yield more horsepower. Tuning on top of that will net even greater yields.

If you ran 100% meth I think it would eat at stuff, but the 50/50 mix works great!
now is it just me or does a supporting vendor offer a plate for a bigger throttle body with a meth injection slot? not put on a bigger throttle body and add meth and youve got some great power comming to the car. just a little thought for the summer time

yea you're right. one of the vendors offers a throttle body spacer with a meth injection nipple. I know rebel autoworx does. I think there is another one too. It would work great too. Or you could just do what I did, I just drilled a whole on the underside of my intake, that way it isn't visible to the naked eye, and screwed the nipple in there. Sleeper FTW!

i love this thread. now some1 just needs to make a poll of the best and most recommended cooling kits or combos for the LSJ, (set aside the cost, i think we're all looking for reliability and the actual ability of the kit to perform with the best result and compatability at any given situation. HURRY, i wanna know so i can buy mine ASAP.

I like the way you think. I have my cobra heat exchanger and brackets from bwoody sitting here waiting upon a day im off work and school to install, and im still waiting on my methanol kit to arrive from AIS....i cant wait to see what this stuff will do for me. does anyone have an estimate of how much horsepower i could have with my mods below?? i have never been dynoed...

You should do the dual pass and set your IC pump to run @ 100% always and set the fan to at least run 30%-40% for when you go to the track. The dual pass made a big difference on Blown 4-banger's car. And running the fan and pump constantly at the track really helps evacuate all the heat from the HE's.
Some of the cars in AZ were doing that as thier normal tune, but unfortunately the computer kinda freaks out with the fan running and sometimes forgets to shut it off after you turn off the car and walk away. That's why it should be a track only thing. The pump actually works fine and Blown 4-banger had his always running.
If you don't want to do it that way or don't access to HP Tuners like that you can make jumpers to replace the fan and pump relays. Here is the how to on that courtesey of WopOnTour.

EDIT:
UPDATE:
I made 222WHP and 201WTQ on the dyno. Tuning helped a ton as my tq curve is phenominal. I went to the drag strip in Kansas City and on my shakedown run I ran a 13.6@100mph. 1/8th mile was a 8.8@80mph and 60ft. was a 2.0. Not bad and I was excited cause I knew I was gonna run faster. Well unfortunately I experienced linkage problems that resulted in no gears and I had to be towed home. On that shakedown run I slipped the clutch off the line at 3Krpms and was shifting at 7Krpms. Plus I discovered, while fixing the linkages, that the slicks were rubbing a tad on the suspension mount. So I need to grind down on that some to make sure that doesn't happen again. Next time at the track will definitely be fun and I'm positive that I'll get into the low 13's with a trap speed near 105.

Added to first post also.
Direct Injection METH And TUNING!
So now I'm looking into changing my meth injection a little. I'm going to be injecting a 90cc nozzle before the throttle body and directly injecting 4 50cc injectors into the intake manifold runners (after the supercharger). This will put me at 290cc's instead of the 300cc that I was using but I'm not injecting some before the supercharger and the rest after. Before I was just injecting before. My IAT1 temps right now are 15 degrees and my IAT2 temps are 90-100degrees. The goal is to keep both IAT1 and IAT2 below 50 degrees. I'll keep you all updated with how it goes.

I think people are gonna give you **** for saying direct injection meth, for a second i thought you were going to somehow tap the head and set up some real crazy ass direct injection. Good luck with the new injectors, looking forward to seeing how much manifold injection and TB injection is better than just the straight up manifold injection.
Good job on finding a combo that works for you!
But why is it that noone has mentioned that methanol injection is not strictly speaking a cooling mod???
Its great that youve hit on this combo, but I think its misleading and pretentious to be telling the world that youve accomplished what you did with merely "cooling mods".
Didnt I catch in here some where that you upgraded to larger fuel injectors?
How about the simple fact that methanol injections benefits are NOT PURELY cooling, in fact I would wager to say that the octane enhancing as well as additional fuel and oxygen, methanol supply actually outweigh its cooling benefits. Meaning yeah it cools, but it also provides extra OXYGEN AND FUEL.
Two things which are required to produce power beyond stock capabilites.
People rag on guys who use nitrous, well guess what, I am sure most of you know this, but all nitrous does is COOL and add OXYGEN. It doesnt add any extra fuel or increase octane as Meth does. So why is it okay to flame on nitrous, but you guys are all over ralliarts vitrual ***** for being so creative and forward thinking for using methanol when its a bigger "cheat" than N20????
Yes methanol injection has been around for years, but its not a cooling mod. WATER INJECTION would be considered more of a cooling mod(although youre still getting an extra cylinder pressure increase even with pure water, do to the creation of steam in the combustion chamber{its this extra pressure that accounts for the additional torque that N20, H20 and CH3OH injection are known for}, but youve gotta have pretty big ***** to be strutting around extolling the virtues of cooling system mods when the only true cooling system mod you made is the heat exchanger and the bypass arrangement, which by my reckoning most of the guys running good numbers on this site already did.
Youve done a good job geting the most out of an essentially stock engine, but its boastful and arrogant to be running around claiming innovation and cooling mods are the reason. When the truth lies closer to the fact that youre adding more and higher octane fuel to the party.
