New Owner Question

[Adam]

Boxster makes the juice from 5k-7,200k rpm. This engine is not a low-mid rpm torque monster like a 5.7L corvette engine....particulary the 2.7L. You have to keep the revs up to extract decent power.

Thanks for all your help - here's a picture of her - not the best one, but you get the idea...

Glad to finally be a part of the Porsche family -

If you were ever on Long Island I'd have to take you out some time...
I just bought my first porsche (also my first manual) and I've never driven stick before so i figured that it'd mess up my engine if i shifted past 3k...

so i was disappointed and told my friends "its not as fast as you'd think it would be"

after reading this i took it out on the parkway and did some 5k-7k shifting and it was like a completely different car... so much more fun to drive haha
thanks

That's a nice looking ride C5150. A classic already.

I'm glad someone brought this up. I've been shifting around 3k so I'll try some 5k shifting tonight. Thanks guys.

wow... really?

It's funny; I read these posts and thought "wow, I can't believe these people have never taken their Boxsters past 3k rpm!!!", and then I thought back to the last few months of my life, driving back and forth to work at 65 mph, running errands on weekends and being careful not to jar the wife or the dog too much, and it occured to me that I also haven't really enjoyed the higher RPM's in a while.

I think I'll go for a drive at lunch today.

It would be germane to this thread to bring up two issues:

1. Every time you redline it, your Boxster's computer records it permanently. This gives Porsche the ammo they need when your engine blows out, forcing you to pay for it. My mechanic says that they don't even clear it out (or can't clear it out) after they replace a blown out engine... so you have to carry the sins of the previous owners and the way a previous engine was treated with the car for a lifetime.

2. Power does not increase to the redline and beyond it. In a 2.5 or a 2.7, by the time you hit 6300 RPM or so you've sqeezed all the HP and TQ out of the engine. Going beyond this simply wastes fuel and is unnecessarily hard on your engine.

I've written it here before, and I shall write it again just to remind myself of it...

If I am ever lucky enough to buy a brand new Porsche, I will not sign the papers and take possession of it until I see a PST tool's display myself to insure some idiot on a test drive hasn't repeatedly redlined the car before I bought it. If you ask me, those couple of hundred miles on the Porsches that sit on the lot are the hardest engine miles that car may ever see. Lord knows on a test drive I put my foot in it to see what a car can do, so the next guy is no different!

And yes, I know the factory takes the brand new cars out on a track for a test drive and they probably redline it at least once to see if it can handle it, and that may be on the computer... but if I see 20 or more redlines on a new car with 200 miles on it, I'm afraid I would have to drive away from the dealership in the car I drove there.

[Houston C4S]

May I add a few words here?

These engines, at least the 3.6 and the 2.7 Box that I drive have
redlines, meaning the rev limits, of 7,300. The reading I have done
tells me that the computer's black box history recorder thingy (that
is a technical term) records two types of over-rev conditions.

Forgive me if I don't recall what their names for them are, but
one is where you exceed the rev limit upon acceleration and invoke
the rev limiter function of the DME. You are not hurting the engine
by doing so, but it is indicative of your driving style. And it gets
recorded.


The other is a hard over-rev. This is where you are winding out
third, let's say, nearing 7,000 rpm and 100 mph, right?

As you grab for a fast shift into fourth (which, in my opinion,
you never need to make a really fast shift -- these are not
drag cars) as a result of over-enthusiasm, inexperience or
perhaps alcohol induced state of "I can out run that Mustang!"
-- whatever, but you instead select second gear.

As you let the clutch out (if it didn't already blow up first)
and if your engine doesn't grenade right there (which it likely
will), then Mr. Black Box will let Porsche know you revved it
to a zillion rpm. And you get to pay for your new engine. As
you should.

Even if you just downshift a tad early, but over-rev the engine
it would be recorded as a hard over-rev.

Anyway, those are the two types of conditions that I understand
are recorded.

But these engines are Porsches and are designed to run at any
speed less than the indicated "red line." I don't know about your
2.5, Randall, but the 2.7 runs to 7,300 and the resonance flap
(which yours does not have) does not even open until 5,500 rpm.

So the moral of my little story is this:

To enjoy your car a long time, change the oil often, use factory
stuff (filters, etc.), warm it up completely before any heavy
throttle or rpm use, rev it within reason -- meaning don't hit
the rev limiter -- and keep in mind that high rpm and open
throttle = high fuel consumption.

And shift reasonably slowly, which saves your synchronizers
in the trans, don't miss your shifts and enjoy a great car.

Have a Boxster day...
