Flinte, the manual is very correct!

Keep her under 4,200 RPM. Don't lug the engine. Exercise the gears, for example down shift to 5th for 10-15 minutes, then 3rd for 5-10 minutes, and then back upto 6th for 45 minutes, and cycle again when on a long trip. Get some long drives in. And I also changed my oil, at the dealership, at the 1,000 mile mark for added protection, long term.

Tires "scrub-in" in about 200 miles.

Easy on the brakes for a few hundred miles too!!

Your car will love you for the above!!

There is no "break in" period for Porsches in the RoW (Rest of the World). It may have to do more with the American Legal system/lawyers, and getting used to the car. Porsche revs the sh*t out of the engines in the factory anyway on the dyno for at least 30 minutes -which is considered the crucial break in period.

Sure is, like white987s said. You would think with the deflector plate on the intake side it is not functional. I don't know how it could breathe with it. I removed mine, and dyno seems to suggest it has measurable HP increase in the upper RPMS. Ken at caymanclub.net (where you can learn to do it too) got a 13 rwhp increase between total stock and then removing the plate. Results will probably vary, but I believe it does provide a positive difference on mine, so I would reccomend it.

One dyno run does not prove a significant difference. The 13 HP is probably within the dyno measurements limit of error. I find it hard to believe that Porsche spends millions of dollars designing/maximizing a car, and would fail to boost HP by 13 just by removing a splash guard. Do you really believe some backyard car enthusiast in 30 minutes found something that 100s of Porsche engineers somehow overlooked/ or did not consider?

Show me the averages after 10 dyno runs with and without the deflector plate - I'm willing to bet there is no significant HP difference.

What might be my chance of success in transplanting the hybrid drive system, ICE, MG1/MG2, etc, from a wrecked FWD Prius to a RWD Cayman, keeping the Cayman's RWD aspects?

Then recover some of the Cayman's "GO" by adding a SuperCharger driven by an A/C motor using a variable frequency drive powered by the 270 hybrid battery.

What do yawl think...?

All that extra weight will slow down your car, decrease the handling, increase braking distance, and diminish the valuable Porsche "feel".

Why do you want to do this? Porsche engineers spent A LOT of time perfecting the car. Enjoy it as it is.

Porsche states that the plate over the air intake does NOT restrict airflow, and removing it does not provide HP gain.
