Exactly. Thank you for picking up exactly what I asked in my first post.

 

Thank you Brian. Not a problem ACR, I think the MB board had more respone to Code3's intercooler you might try and search over there.

 

Hi, I ordered the C3P-Intercooler and I can post some results after datalogging. What I see from Brandons Datalogs is that the overall cooling after a short run is nearly the same compared to the stock unit, but the IATs are recovering much faster after letting off the throttle. This should be very helpful for me on the Autobahn after a hard run, letting off for a few seconds and then do a second run! I think it will be worth the money for my daily driving on the Autobahn, although its not a cheap mod...

Regards

 

I do not see anyone in this thread confusing an intercooler for a heat exchanger. Where did you see that?

You guys can spend a few thousand dollars upgrading your IC, HE and so on with minimal results or you can spend $200 to $500 and see big results. I know which route I am going.

 

I think the IC was located where it is to keep pressure drop to a minimum. This I beleive makes ths combination more efficient than a remotely located unit? Any thoughts or am I completel off base?

 

Can you tell us some more details? Is it safe? Thanks.

 

I will look up the link to the alcohol injection forum, you would not believe the detailed info over there. I have some before and after dyno runs on my old supercharged car if I can find them I will show you as well. You can also run a mix of 80% methanol and 20% nitromethane (I have 2 gallons at the house waiting on the srt6 ) and you will pick up another 20whp or so with that when at the track. I have mine custom mixed instead of purchasing the pre-mixed which is about 200% more expensive. A base kit is very simple to install and the kits with the progressive controllers that tie into your MAP sensor are a little more involved but work better for partial throttle response. I have never installed a progressive controller but there is not a lot to it from what I have read up on them. I am ordering mine sometime this week, I may do the progressive controller kit but I am not sure yet. I do plan to run a small 3gph nozzle and run more water than meth since I plan to use it mainly for cooling. The more water you run the cooler the temps and the less it alters your a/f ratio and visa versa for more meth and less water. It just depends on what you want to do. I plan to run 70% water/30% meth. When at the track I am going to run the methanol/nitromethane mix.

Here are some advantages:

• Lower air temperatures by 50-200+ degrees
• Reduces cylinder temperatures by 200+ degrees
• Increase your 87-93 pump gas by 15-20+ points
• Increase horsepower safely by 10-15%
• Allows you to safely run more boost and timing
• Cools and protects the tops of your pistons
• Longer more stable combustion expansion and progression
• Removes carbon build up from combustion chambers, pistons and valves
• Reduces & helps eliminate damaging engine detonation & pre-ignition
• No need for expensive racing fuel or additives

 

Thanks. I think ECU-Adaption will be needed and from what I heard, you have to be careful to adjust the water/alcohol injection very accurate, control water/alcohol level in your tank etc... Some people had engine-problems with such a setup... Maybe it is more for the "hardcore" dragracer than the daily driver. If it is installed correctly, it sure gives more power...

 

nah it is only an issue if you go crazy and start replacing too much fuel with alcohol and go nuts with the timing advance.

 

please be careful with nitro, as it will drastically lower et's but it is very hard on the engine. i do not have doubts to your knowledge on this but i wanted to put up a warnign for those that dont know better.

 

Hell I am no car genius by any means lol.

Spraying with a 3gph nozzle using 20% nitromethane=.6gph. Without being exact and breaking out the calculator the 3gph spray is about 10.5% of the total volume of fuel being sprayed (using a rough 1800cc spray volume total for the stock injectors) and .6gph would equal around 32cc which would be around 1.7% of the total volume of fuel going to the motor so spraying 1.7% nitromethane would be safe since only .28% of the total fuel volume per cyl would be nitromethane. (Rough estimate but relatively close).

BUT if you did go crazy with it and sprayed too much or if the nitro/meth mix would seperate and you sprayed a pure shot of the nitro then it could be trouble. You have to be VERY careful how you mix that stuff, it wants to seperate if you do not get the percentages right. Too much or too little nitro in the methanol and it will seperate to the bottom of the tank and you risk spraying 100% nitromethane in your intake.


Edit:
Oh, and when using nitromethane to spray it does the opposite of the methanol. It makes your car run a little leaner. If you spray wather/meth mix you richen up by about .6 a/f ratio but if you add nitro to the mix it will actually lean out a little.

 

Can you please explain how the 1.7% total volume is somehow diluted when it gets to the cylinders? Since these are percentages (i.e. ratios), I would think 1.7% of fuel volume would stay constant...

 

1.7% divided by 6 cyl.

 

Hey mrphoto - I didn't say I couldn't figure out the math you were applying... perhaps I should've just been more direct and said "I think your calculation is wrong" - if you were dealing with a QUANTITY (i.e. cc's), then yes absolutely you would divide by 6 to get the individual cylinder amounts... e.g. 60 cc's total would wind up being 10 cc's per cylinder. However, if you're dealing with a RATIO (i.e. a percentage), then 1.7% total fuel ratio before the cylinders would still be 1.7% in each cylinder.

 

Man, you guys are good at math, because I couldn't figure this stuff out with a calculator,personal tutor, and a hooked on phonics booklet. You guys are good.

 

Alcohol injection is usually for higher hp applications where cylinder temps need to be cooled down. You can run it but it does increase cylinder pressure, which is harder on head gaskets. It is usually used more with diesels because they can climb too 2000* degrees on egt's on a 1/4 mile drag on a hot tune, or sled pulling. I don't think I personally would go that route because you need to mount a reservoir bottle or hook up to the winshield washer tank. Usually it is a trouble free set-up, once you dial it in. But you always have to remember to fill and check the tank.

 

Mutt is selling his meth injection kit - along with other goodies..better hurry!

 

that is not true at all, you can use meth injection on any car. you can use it on a n/a car or a fi car. it cools temps, raises octane and all the other benefits i posted above. as for increasing cyl pressure, it does a minute amount because it is only spraying a very fine mist. you would have to be spraying an insaine amount to raise cyl pressure.

whoopity doo yeah you can take 2 seconds to mount a tank or you can tap into the stock washer tank which has a low level light on your dash. a tank lasts around 400 miles.

 

Just browsing the forum and noticed alcohol=increased HP. I will test this theory tonight and post my results.

I will not be injecting alcohol simply pouring it the old fasioned way.

CHEERS!!!

 

You are going to add the alcohol to the fuel tank? How much are you adding and what grade alcohol??

Please let us know, thanks
