How do you come up with that # Dan? You must have some kind of special engine kit from Porsche.

My tach shows redline at 7200. I checked in the owners manual under engine specs and no redline is called out. The tach is the only clue they give. Well, that and the info Slow posted from the tech manual. I see nothing that would indicate a redline over 7200.

It's in the workshop manual. Trust me. You just have to look for it. Porsche doesn't mark their tachs to that level of detail. They used to, but not for these regular mass-produced cars. 7300 is for both the 997 and 997S (first generation--I can't speak for the 997.2 engines.)

(Other useful technical information is found within the factory workshop manual that can be a source of other disputes! For example, the 997 engines are supposed to have a consumption of oil of 500 cubic centimeter = 0.528 344 104 72 quart [US, liquid] over 1000 kilometers (620 miles).)

That is the rev limiter range. PDK is a direct connection tranny without the soft limiting torque converter. It is not an over-rev. Zone is a legitimate rev-limiter range.

OK then.

Now riddle me this. Where did you get the workshop manual info?. I'd love to have this stuff! Do you have access to the whole manual?

I'd ask Slow, but he only likes to dole out bits and pieces it seems. Some kind of big secret!

Thanks

I have the whole manual. There's a lot of good stuff in it. I believe the redline info is also in some of their sales literature as well. You can probably get your own from Porsche.

So the question remains can you overrev w/PDK?

This is interesting.

According to the Service Information Technik MY 2005 published 1.7.2005 for the Carrera S and the Service Information Technik MY 2005 published 1.5.2005 for the Carrera the rev limiter of both engines is at 7300rpm.

Now in the official PIWIS and under Technical Information Service in Vehicle Analysis Log: Evaluating overspeed events, the rev limiter and starting point of an overspeed events is at 7200rpm for range 1.

Both are official documents, with the VAL being newer and specific to the rev ranges and a dealer tool for evaluating overspeed events and warranty claims.

Both can't be correct..so a gentleman with a durametric or equivalent and a 997.1 will log for us the max rpm and solve the puzzle, although I think that 7300 is the correct one..

RollingArt

Probably not.

It's my understanding that this manual is NOT available from the dealer network.

Let me ask this way. Where did you get yours? PM if necessary?

Haven't read all the posts here so maybe this was posted previously but this is what my Porsche dealer provided me re: the various ranges.

Tell your dealer to do his homework and stop sharing inaccurate information.
I don't want to see the wrong values all over Rennlist.

Thanks.

John,

I think your response to JHBrennan above was a little overbearing and quite frankly, uncalled for, especially in light of your previous post (#52 of this thread).

In post #52, (which is the top post I quoted) you state that Service Information Technik states the rev limiter to be at 7,300 while VAL states it to be 7,200.

So which is it? Are you ABSOLUTELY 100% CERTAIN rev range 1 starts at 7,200 as shown in a link (included below) you referenced on the previous page?.... or is it 7,300 as shown on JHBrennan's chart?

Either way, there is no need to shoot the messenger. Personally I don't care if it is 7,200 or 7,300, I just didn't like the tone of your post, ESPECIALLY from a Moderator!

Here is your link 997.1 Rev Ranges.

Rev range 1: 7,200 -1 ... to 7,500 -1
Rev range 2: 7,500 -1 ... to 7,700 -1
Rev range 3: 7,700 -1 ... to 7,900 -1
Rev range 4: 7,900 -1 ... to 8,400 -1
Rev range 5: 8,400 -1 ... to 9,500 -1
Rev range 6: over 9,500 -1

Here is JHBrennan's chart.

Interesting chart, but what's a Boxter?

Tim you are absolutely right, it was rude and I apologize to everyone and especially to member jhbrennan.

I should have tried to explain it better but as I was reading and writing from the iPhone's screen, I noticed that the GT3 / 997 turbo values mentioned in the above table were wrong lost my temper and posted.

The truth is that we had this discussion about over-rev ranges so many times that I don't want to see wrong numbers being recirculated around the forums anymore, especially when I'm paying out of my own money for Rennlist to have access to the official and correct PIWIS data (same data used by the Porsche Centres).

Best,

John,

Thanks for the response. I appreciate your understanding of my comments.

Your comment makes more sense now given the Turbo context, but since were were discussing the Carrera/S, I couldn't understand the comment. I guess had you mentioned the Turbo numbers were wrong, then it would have put it in context. Honestly, I didn't even look at the Turbo numbers. Even if I had, I wouldn't have known if they were wrong or right, because admitedly, I know very little detail about the Turbos.

Thanks!

jhbrennan

No offense taken...I would like to know the correct ranges for the 997.1 turbo if someone will post. Thanks.
