True, but since it's not stated in the quote I was responding to I left it out. Even if it did, it's not possible to get the IAT within 3% of ambient even with an intercooler, unless boost is so low as to make it pointless in the first place.

My point is, compressing air heats it up. Unless they've found a way to cheat the laws of thermodynamics (which would be worth $Billions), it's just Marketing BS - which always gets me on a rant no matter what the product is.

I've just spoken to the official distributor for Australia and his recommended me something in the C30 series.

Has anyone had first hand experience using a c30 on a k20? What sized c30 and what sized pulley to be used for optimum power with reliability?

Ambient temp: 70 F
Pressure ratio 15 + 7 / 15 = 1.47

[(70 + 460) * 1.115] - 460 = 131 deg F temp rise.

It's not even that good since they use an ordinary turbo impeller; the actual figure will be about 30% higher. I wonder what marketing fine print makes it okay to make such claims.

Don't drink Marketing Kool-aid, it's seldom as presented.
I'm sorry, I meant to type 30%, my fault. Still better than the temperature raise versus turbo setups.

I still don't see how it can be less because on the compressor side, a turbo and this thing are identical. Maybe because the hot turbine section isn't there? OTOH, the gearbox makes its own heat, enough that it needs a cooler.

I don't think they are making kits for every chassis with a K series in it, that's why they have the race version where you have to make your own intercooler and intercooler piping, supporting mods. I might be wrong but I'm pretty sure that's how they are taking care of it.

The Kraftwerks uses friction gears. I dont think the heat will be much, but i could be wrong.

You are right Ben.

The Rotrex oil never goes over 175°F and runs about 100-140°F. The traction drive stays at a relatively low temperature compared to turbines (1000+°F) in a turbocharged application.

Hi,

I am wondering if there's a kit for my DC5R, running stock compression, but I would like to keep the airconditioning.

I have found the roots supercharger kit but it has no intercooler, and the charged air temp is too high. Someone has managed to install this roots charger with water-injection kit on a stock K20a engine, and getting decent power of 340hp at crank.

http://www.drivencrazy.com.sg/index.php/archives/35

Pls advise if there is such a kit.

Thks.
