Ah, air to water....now i remember reading that someplace. That explains the price. I would image when its hot outside that it would still run better than it did without it.....i would sure hope anyway

 

I have to disagree, partly from wishful thinking, and partly from all these guys on LS1 Tech saying that their intercoolers keep them at only 5-10 degrees above ambient. If they're not lying (and I hope not, because of how much a pain in the *** my install is being), then the difference between 110 IAT and 160 on a 100 degree day should make substantially more power. I won't be able to back up my argument until it gets hot out again.

 

Most coolers installed "as is" are only about 70% efficient. Like the LS1 guys, I have tweeked my cooler (air/water) with a bigger front radiator and a Meziere 1" 20 gal/hr pump instead of the stock wimpy .5" Bosch. 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.

 

Linda, who did you speak to and how much did they take off for the craptronics? Can you give me a list of parts you are going to get? Thanx. You can email me or PM me.

 

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....

pretty sure these are direct fit with no adjustments to the rails needed.

$360 for 8 is not to shabby.

 

So before all the tweaking what where your AIT's at on a WOT run? Then what where they with the tweaks? That bigger pump and Hxr might be great, but the balance is tricky, I am not sold that a bigger faster pump is all that great of an idea(not that a small one is either). Seems moving the water through the intercooler faster is great but keeping it moving throught the Hxr at the same fast speeds isn't helpful either. Hence the low effiency rate. The larger Hxr will help with that creating more surface space...hence the "slowing" of the time it takes the water to go through the Hxr. Seems to be your case, that's why I am curious of your differences in AIT's...before and after.

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

 

are 42lb hr injectors even going to be enough on an 8.1L with 6psi of boost?

 

Yup, looks like...cool.

Thats what Westers, Kenne Bell, and Delphi recommend, so I sure hope so. Anything larger and I think I will have to make rail, pump, and connector changes. Dont really wanna do that.
