Tell us how you REALLY feel Vinnie

 

tim thats about the helpfullest GD thing ive seen in a while, i called magnuson to see if they had something like that for the 112. we outta come up with some ways to make this thing run like the KB there has to be a way. i think someone like chris from works would be smart since he has the way to do it, would be to build a rear inlet case for these things, that a new plenum and some porting letting us use the rotors and snout would be a better idea.

 

Interesting! From the site:

"Question: Don't you lose horsepower, due to the extra torque required to drive the a/c compressor?

Answer: No. Many vehicle computer systems automatically deactivate the a/c clutch circuit at about 75% of full throttle. For those which do not, just manually turn off the a/c switch just prior to max acceleration. Remember, the purpose of the insulated liquid reservoir is to store pre-cooled liquid for future use. That means that the intercooler receives a steady stream of cold liquid even AFTER the compressor is disengaged because it is being fed by the electric water pump. When you order a reservoir, be sure it is large enough to prevent a power fade down the stretch."

Do our trucks have this "75% cutout" of the compressor?

 

I know at WOT they do... very possible it's at 75%.

Cool. WOT is good enough. At open track events, other than some scary sections, I'm usually either braking or WOT.

This could get interesting. Right now I'm toying with the idea of intercooler upgrades, but want to get some baseline data first. So I need to measure the intercooler fluid temps stock

Then JDM, then with fans, then, perhaps, with A/C chilling. I have some serious reservations about dumping $2K on intercooling on my stock engine, but would really like to collect data on intercooler mods.

 

This really got my gears turning too. I read about nitrous, water/alcohol, heat exchangers, etc... all in the name of power and all they are doing is COOLING things down.
I'm thinking something like cpu radiator cooling parts could be VERY useful.

Keep in touch. Everytime this comes up; I get a hair in my a$$ to start experimenting....

You need to get Chet's old super chiller setup. I think he is selling it for $500. They guy who did all of his work says he got a 20° decrease in water temps with it...
here is his email. Darren Nist I think is his name. He is out there in CA.
Here is what the setup looks like. Can't use it at the track. Everything is supposed to be included...


I'm not getting anything out of this deal. Just strictly passing along info.

 

Does anyone mind if I put my Bannana in the Dogpatch??

Okay this thread is way over me here. LOL

 

Why is that?

John

 

It has to be used with the airconditioner. Even thought the A/C turns off at WOT you would still be dripping in the stagging lanes. They don't like that.

 

"At the track" means something completely different to me, Easter. Open track, baby.

NASA, the sanctioning body whose events I have been going to lately, actually encourage the use of the A/C when lined up to go out. A cool driver is an alert driver. Now I may have a secret weapon. Bwwwwaaahhhh.

 

Tim, very very helpful informative info. To anybody not intending to road race, why not do like all the Pro 50 and Super street outlaw car? Get a 10 gallon cell, fill it with ice and go. In 90 degree heat it takes about 4 bags of ice. I realize the ice bags can cost but so does this a/c cooler. I guess this is the same arguement that we use to have with our Mustangs. Blowers Vs N20, blower is always there (a/c system) and you dont have to worry about filling a bottle (Ice tank)

 

Another consideration is weight. Water is 8 lbs per gallon. That would make the fuel cell 80-90 lbs. The chiller unit might weigh 10. But ice water in the intercooler is a time-tested trick.

 

I think I maybe 'reinventing' the wheel; but this seems appropriate.
Why not switch to a larger intercooler resevoir? Also- I understand that anti-freeze doesn't have very good heat transfer properties compared to distilled water .... I'll have to search on this ... later.

Also- I've been kicking around with the 'extreme overclocking' computer geeks about mini refrigeration units. It seems almost practical to try to get one of these up and running to chill the intercooler resevoir/fluid ... and if you look hard enough you can find these used mini fridges way cheap <$50 Biggest pain in my **** would be wiring.

dang- no spell check

 

i wouldn't even think about running at the track with out my air condition on and i love my lightning
