i have a gsr with i/h/c/e would a alcohol injection kit do anything for my car at all.

anyone kno anything about alcohol injection

 

I wouldn't touch that with a ten foot pole.

Maybe a water injection kit.

But why thin out the mixture??

Wish i had racing gas??? what does that mean? higher octane?? i didnt think alcohol made an octane change. I do know it burns easier. Which confuses me on the with

"It suppresses detonation so well it is like having a full tank of race gas at all times. Have you ever had an encounter where it left you saying " I wish I had some race gas in my tank and I would have stomped him..."

as octane is a retarder not an accelerator in ignition.



i wanna know too. i wont ever use it. but i'd like to know

i'd think it would lean you out and cause detonation. :/

 

I used alcohol/water injection on my turbo setup. Works superb

 

thanks guy's anyone else

 

i doubt it would help in your situation. you should be able to get all the timing advance you need from pump gas with that setup.

we use methanol injection on some turbo cars and it works great. it cools the intake charge ALOT (35 deg ait's on a 75 deg day at 25psi on the dyno) and is an exelent knock supressant.

 

so it doesnt affect the fuel mixture?

ive personally dealt with the JR water injection system worked great for cooling charge temps on a b16a wit JR charger.

is the action similiar?

 

the effect on the fuel mixture depends on the ammount of methanl you inject. the way i have done it is to use a solid state relay and connect the pump to an injector output on the ems. that way i can tune the ammount of methanol i want. we usually mix it 50/50 with water.

 

don't you have any problem with corrosion with methanol injection when let in your garage for a certain periode of time?

and what about propane injection? I haven't seen a lot of people using them, but it looks like a good way to lower detonation!

 

we havent seen any corrosion at all in the system. it normally stays full and we never flush it. its been in the car since october.

i dont like propane... ***** way to flamable. i just have some conserns of riding around wiht a 20lb propane cylinder in my car.

You have a lot of research to do. Alcohol injection is nothing new in the Automotive Performance industry as its been around for about more than 25 years.

But before you go crazy trying to research. Ask yourself this question....

Why does the Alchohol burn so easy ? And what are the benefits ?

 

I'm a believer! I consider alcohol injection to be mandatory in all boosted applications. On your particular set up, it won't really help that much. The benefits of alcohol injection are well documented on the internet. It's been around for years...

Here's a pic of my set up.

 

Alcohol is a safe additive to use. Since the 1960s, all cars have been manufactured with alcohol resistant hoses, connections, O-rings, seals, and plastics. This was necessary because of the popular use of alcohol base gas line antifreeze additives, and the use of ethanol mixes in automotive fuel. But, the biggest advantage of alcohol injection is that it is an "on demand" system for both the street, or strip. Especially for street applications, the realities are that, for most drivers, less than 2 percent of the time high turbo boost is actually used. So, the argument becomes: Why have the fuel tank filled with high price race gas, or add a couple of gallons of toluene with every tank, when the higher knock threshold protection is only needed for those relatively brief events closer to WOT? Tuning with alcohol injection only for those boost levels when it's really needed to raise the knock threshold (higher octane equivalent) also accounts for the small quantities of alcohol consumed.

Tuning to the edge of the envelope quickly bumps into the knock limits of the fuel being used. Alcohol injection can increase the knock threshold of 91-93 octane pump gas to the equivalent of the range of 104-108 octane. The relatively small amounts of alcohol injected doesn't increase the total fuel energy much, and only adds small amounts of additional oxygen. While methanol alcohol has an equivalent octane rating of 108, the main effect is the result of large, rapid evaporatative cooling of the intake air. Also, small amounts of water added help control the flame front in the cylinder for smooth, controlled cylinder pressure rises at ignition (the opposite of knock). This effect also shows up as a very significant reduction of 60 to 100 degees (F) of the EGT at WOT. The cooling effect of alcohol is also used on supercharged (up to 8 pounds boost) engines with no IC. The effect is like adding an intercooler. Alcohol injection is a very mature technology that has been in widespread use, especially since WWII, with lots of experience, and data availble. There is no need to re-invent the wheel, or plow any new ground. It is a reliable, cost effective way, to raise the knock threshold of the fuel being used. So, the answer to the question: "Why alcohol injection?" is simply "Why not?"
