Four Thou off, doesn't that mean they are at 7K$ for a s/c system w/o any cooling methods?

Hmmm...the Vortech on my Saleen didn't have any supplemental cooling system either. In the 12's on street tires in an automatic/convertible. Never even came close to overheating. LOL Everyone should chill - no pun intended. Can't we all just get along?

Ummm no... not on this topic.
<insert long drawn out explaination we've already discussed before here>
heat expands, cold compresses, the goal of the SC is to compress air. The cooler the air, the more it'll compress... density... compression... big boom
12 second runs with an SC verse long term drivability and reliable are not comparible.
With my stock IC, at an autox I can feel it progressively drag it's feet with contigious runs for 40 -50 seconds per lap.
blah blah blah dead topic

I sell/install a non-intercooled S/C system for my Viper clients and the installed/tuned cost is roughly $8,500.00 out the door. This system when bolted to a bone stock V10 will produce roughly 530rwhp and 550rwtq. The closest system that is intercooled will cost roughly $15K plus installed, but will produce an additional 100HP and TQ. Does that mean the intercooled system is a "better" system? No! What it means is you just paid almost double for a more efficient system. Can you compare these (2) systems given the price differential? No, how could you, it's like comparing the "F40 to an F60." Right? So, how could the Kleemann system be compared to the HPS? Quite simply, it can't! The non-intercooled HPS system, given it's price, is pretty good bang for your buck. Right? BTW, there are things called "aftercoolers" that can be engineered for positive displacement S/C's, which is what I believe the Kleemann system utilizes. If HPS were to engineer such a device, then you could compare "Apples to Apples" for a 1/3 of what the Kleemann system would cost. I'm rambling...
Is the Kleemann head unit manufatured by AutoRotor?

Kleemann uses an intercooler and an aftercooler!
Intercoolers are not always necessary, but in many cars can be the difference between running safely and detonation. Do a search for the HPS dyno's on 91 octane and see for your self. Even without the a/f ratio (which I guess no one will ever know), you can see that the car leans out on top where the power curve stops climbing and becomes wavy. Board members, tuners, and even Kleemann offered advice that could have actually helped build a bettter product, but it has to this day been ignored.
Also, the Dodge Viper has a compression ratio of 9.6:1. The 430 engine is 10:1 and the 55 is 11:1. As you know there is a big difference in there. We're actually lowering the compression ratio on our 6.2K CLK in order to safely handle boost.

I can't get too much into it, but we have changed the pistons to lower the compression and sleeved the cylinders to keep them running smoothly. I'll let the owner chime in when he chooses.
I have not verified whether the HPS system detonates or not, but I personally would not run boost on a high compression motor w/ 91 octane and no intercooler. Something may start out cheaper, and later wind up costing more.
Nevertheless, I don't want to start another endless debate, and I'm sure that the majority of readers don't want to read one. I'm going to step back from here, and take a breather...
