Reving The Engine

[emguy]

Hi all,

I just got a new 997 GT3.....I used to have a Cerrera S and I remember that the owner's manula stated that one should not exceed 4500 rpm in the firts five minutes of driving....I have not seen the same warning on the Gt3 manual.....Does this rule or a similar apply to this car?

Thanks a lot

Congrats on the new car!

I always keep the RPM's below 4,000 until the engine has come up to operating temp.

Emguy, you should also follow proper engine brake-in too, since the car is new. Takes about 2,200 mils.

As a normal procedure, I like to see 200'F before putting any load on the engine, and ditto keeping the RPM under 4200 until the indicated temp is reached.

Regarding breakin, I posted a response (at the bottom of the link shown) that might be helpful.

Why does Porsche pick 4,200 RPM's for brake-in? Does this have anything to do with the VarioCam??

There is probably a lot of fudge in there. They tell you 4200 because you will go past that sometimes and they want you to take it easy. You will probably hit 5K from time to time. If they told you 5K, you would hit 6K and so forth.

What is most important is getting as much break in time with the engine and systems warmed up. They really mean it when they tell you to take a few long trips. I took a 1,000 mile road trip the day after I got mine.. It was a pleasure.

Keep in mind that many systems need break in. The steering loosens up. The transmission does too - noticeably after 2K. You always need to baby the engine and tranny when cold - but especially during break in.

And get the car aligned. They are never spot on from the factory. Might as well do this after break in. The suspension may settle a touch and you will be taking it easy in the meantime...... RIGHT????
