If you decide to market this, and once you set a price point (so I know how much to start saving for) consider me a future customer!!!

I am dead serious, that is the most perfect first test drive I have ever taken, period, in any car, ever!!!!!

• I let her idle up to operating temperature and had to add some fuel to my old map
• I then had a fair amount of hesitation on very slight throttle so I upped the TPS enrichment
• Played with fuel until the fuel trims leveled out close to zero at idle
• Shut her off
• Double checked everything by look, feel, touch
• Started her up and went for a 5 - 10 minute drive when all I set out to do was go to the first stop sign and back

I'm not kidding, aside from a very slight hesitation with a feather foot on the throttle, it was brilliant! I ended up getting her up to 72.8% throttle (low rpm), 13.4% engine load and about 45 mph.

I was also very impressed with the BOV noise as it was non existent at idle or cruise. You hear it a little rolling to a stop or on throttle release but nothing like the jet sound of the old C30 on a 1.8l. Some might even like it this way as it wasn't annoying at all. However, I will still end up quieting it down.

Now get this!!!!!! I'm sure this will change over a much longer run but the IAT's were very impressive. With the stock intake I was seeing an early 25 degrees delta between the TB and ambient temps. This quickly went to 35 on the highway and ultimately 50 degrees on a hot day.

In this 10 minute drive, it was 95 degrees outside and the IATs never went above 108 at a stop sign!!!!!!!!!! Then when I hit the gas, it would go down to 104 then level off at about 106 while at a 35 mph cruise!

Also, coolant temps never went above 198 and seemed to hover closer to 196 or so.

That is absolutely freaking awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

For the Street:

· A Rotrex is better for under the hood temps
o You can typically push it harder, faster, longer than a turbo at a comparable power level
· It typically creates a nice linear power band that is excellent for drivability
o It behaves itself enough for grandma to drive unless she puts it to the floor
o Its linear power band is fluid and increases until redline
o No severe excess of torque in the mid range then a gradual decline in output as with a large single turbo
o A Rotrex is going to enhance the natural characteristics of the motor
§ In fact, the Rotrex will make it feel quite simply, like you bolted a much larger motor in place
· The Rotrex has No lag whatsoever, throttle response is instant and almost always improved
o The Rotrex is always flowing more air then the motor needs so it ALWAYS has power on tap
o A car with a Rotrex always feels like it is ready to pounce
· The fun factor is through the roof for all of the above

What do I mean by this last comment?

The torque delivery of the Rotrex is linear and increases until redline. This equates to the feeling of sitting in a rocket that gets faster and faster and faster until you let off the gas. A turbo has a different feel. A turbo setup when matched HP for HP to a Rotrex making large numbers on a motor will typically hit incredibly hard at its boost threshold then taper off to redline.

That said, the Rotrex is not going to provide an ungodly kick in the pants. Instead, it is nice and smooth and predictable.

If you like controlled fury, the Rotrex is for you. If you like a wild *** kick in the pants and hanging on to life by a thread, maybe the turbo is better.

IMHO ->

Street, Twisties, The Dragon - I say Rotrex

Dragstrip - I say turbo and some monster tires to keep that torque to the ground!

There is a lot more to this discussion as you could also go off into electronic boost control, WI, etc. The answer is Yes, you could build a turbo to match the characteristics of a Rotrex AND have the ability to turn up the boost at will. However, at what relative cost and level of complexity?

It really all depends on what you want out of it and your application. Many people think it is about nothing but low end torque. I typically am on that boat, but there is such a thing as too much. Just ask the guys who can never seem to find a tire wide enough to keep their rubber from melting off the rim To me, the Rotrex is the perfect compromise and fits the largest number of "wants" on my well educated wish list.
