The 8.1 intercooler is air-to-water, they're quite a bit more complicated, that's why the price.

At that low a temperature difference a cooler would probably only be 50% efficient. That's just 30* cooler, I think hardly worth the trouble.

I won't be able to back up my argument until it gets hot out again.

I got Whipple to knock off a few bucks cause i dont need the electronics and injectors, but i have to use the savings to buy the new 42lb Multecs. They will run me $400 or better. Maybe this summer or fall i can add that on, should be a simple upgrade too. Im sitting at about $5100 for the S/C, injectors, and the dyno tune i am going to get when Im done. Why are the intercoolers so expensive? Its just a radiator for air isnt it?

His name is Chris, and he is knocking off $800....I just got a call from him last night. He said the website does not have the updated performance info or the updated price info for the new compressors yet. The black, non-intercooled unit is now $4600 (-$800 for the deleted parts I dont need) and to add 6% to the dyno figures that are reported for the 8.1L kit on the site. I will have to sign a letter of release for the the custom kit that will also void my warranty. Now I am just wondering if the $800 savings is worth loosing the entire warranty. Based on others comments who are running the setup like I want to and having no problems at all, i would have to say at this point $800 off is probably worth it. According to Chris it will come with everything except the electronics, exra injectors, and handheld programmer. I would assume (but will confirm before I purchase) that the kit will include:
The compressor
the hardware/brackets
the induction system
the air by-pass valve
instructions
By the way, are the electronics involved at all in the air by-pass valve? Or is it totally vacuum/boost driven?
If you can get past the girl at the front desk, they seem to be very helpful and willing to work with you on getting your project set up. Dont get me wrong, she is a nice girl, I just hate being screened before I talk to someone.

by the way, there is a good sale on the Multec II's here....
http://www.racetronix.com/17113739.html
pretty sure these are direct fit with no adjustments to the rails needed.
$360 for 8 is not to shabby.

I also have a 5 gallon tank to which I can add ice. The air/air guys have their own tricks. The adiabatic efficiency is also a factor. Those turbo guys I hear can get as high as 80-85%. Compared to 50% roots or 75% screw/centrifical that's pretty darn cool boost.
I agree with everybody...it's just a balance of which and in what location under what "normal" operating conditions that one will fall. People in Arizona will certainly complain first of their non-intercooled kits before people here in the northwest. I agree with Linda especially...coin talks!
I say throw a meth/water injection kit on it. Waaaay less money and you WILL notice the difference....for a 1/4th of the price...if that.

Looks air driven to me
