^ Mooty or anyone who might have an answer to these 2 questions ; why would anyone order the option #461 '' rod antenna '' ? I've seen a couple cars with it , yet have seen cars with virtually no options that don't have it . I see it was a no cost option . Also , is there anyplace to check how many cars where built with radio delete ?

Hmm, for me it's a 997 RS over 964 RS any day.

The rod antenna is for those addicted to "talk" radio on the AM dial which the regular integrated antenna in the car is not very good at picking...

^ Thanks - I was puzzled as to why it was an option . I haven't seen a build sheet or window sticker for a car with radio delete , but assume it was a no cost option as it was on my 991 RS ?

IIRC radio delete was only available on 997-2 cars.

Here's a radio delete car, you can ask PNH for the build sheet: https://www.porscheofnorthhouston.co...AC2A99AS783748

When the cars were new I saw a green radio delete car . I may be wrong , but I think you couldn't delete the A/C on the .1 I have seen a handful of .2 cars with radio delete or radio and A/C delete .

Wow, market seems to be coming down a bit on these. I don't know if I should say thanks for posting of be mad that I'm trying not to pick up the phone to give John a call

That's a car has problems from what I recall. It's been for sale on and off for 18+ months, first on Long Island, then PNH. I was just posting it as a reference of a radio-delete example.

on 997.1 RS you could only delete A/C while in 997.2 RS you could delete both A/C and radio. there were 11 radio delete 997.2 RS 3.8 made for North America and 12 radio deleted 997.2 RS 4.0, so 23 total. while not that rare of a number made (23), none were green...

It's been a number of years ; if I have that backwards was there a green .1 without A/C that you know of ?

misterwaterfall

Thanks for the heads up. Could be the reason it's not posted on here.

Do you know if the ROW cars had radio delete as an option ? If so you could at least buy the box / plate and remove the system and have a finished look .

I searched last week to see if this car had been discussed as it seemed unusually reasonable, even with no radio (assuming one sees this as a bug and not a feature). VIN did not pop up but I found it searching for "delete." I found this reference:

According to the GT3 RS registry this one is A/C delete.

Some advice for you guys that own a car, or are looking to pick up a car, and want to ask about a vehicle's DME report/overrevs...

At the end of the day, if you are looking for a cherry as an investment, look for minimal to no range 4-6 overrevs but don't be afraid of overrevs on a DME report in general. Overruns in ranges 1-3 are an expected and common occurrence on a manual transmission car. It is almost impossible to find a used one with nothing on the DME, and they are deemed relatively harmless and meaningless to the point where Porsche will CPO a vehicle with ranges 1-3, and there is no cap on the length of time of overrevs in those ranges or how recently they occurred. If you are looking for a car to drive thoroughly and enjoy and don't care as much about resale affected by DME reports, you can even consider a car with range 4-6 overrevs. However, as they occur at rpm ranges and happen in situations that are more stressful to the engine, you should look for how long ago they occurred and how much time was spent in those higher rpm ranges to err on the side of caution.

Another important thing to keep in mind is that a DME readout does not show the number of overrev occurrences in a particular range. What it shows is the number of ignition cycles that occurred in that overrev range. It is important to ask for this data and analyze it for its true meaning in an educated manner. For example, lets break down a 997 GT3 with a total run time of 280hrs and a DME report that says...

"Number of ignition cycles range 1 ----> 1957/253.5h"
"Number of ignition cycles range 2 ----> 365/137.5h"

This is saying that this GT3 has been in a range 1 overrev status for a total of 1957 ignition cycles and the last occurrence was at the 253.5 hour mark of the engine's run time. Same principle for range 2. To the uneducated this may be frightening, these are big numbers. However, what you want to do is convert these ignition cycles into a length of time for a meaningful reference point. To do this accurately you need a chart breaking down the RPM ranges that dictate the overrev ranges, and this changes from car to car. For your reference....997 GT3 Range 1 Overrevs are between 9000-9200rpm, and Range 2 Overrevs are between 9200-9400rpm. Here is the conversion.

Range 1: 9000rpm/60sec=150rps. These engine have 3 ignition cycles per engine revolution, so 3x150rps=450 ignition cycles per second. 1957 ignition cycles in overrev/450 ignition cycles per second=4.34 seconds of ignition cycles in the Range 1 overrev range.

Same math applies for Range 2, although at 9200rpm as this is where the Range 2 overrev range begins.

Range 2: 9200/60=153.33, 3x153.33=460, 365/460=.79 seconds of ignition cycles in Range 2.

As you can see those big numbers just turned very small, as this GT3 has had a relatively minuscule 4.34 seconds (Range 1) and .79 seconds (Range 2) of total time in an overrev condition throughout it's entire engine life of 280hrs, and they occurred near 30hrs ago in run time. This car should be considered perfect, it would be CPO'd by Porsche's standards. That goes the same for essentially any length of time in Ranges 1-3, and as recent as 5 minutes ago. Ranges 4-6 are essentially the only ones worth doing these calculations on and determining the length of time and how recent they were.

I hope this helps provide some insight on how to ask the right questions on the overrev topic, as simply asking "does the car have overrevs" can unfortunately and unnecessarily leave a passionate owner, or potential owner, turned off and unenthusiastic about their car or the one they'd like to pick up. That little worry in the back of your head can unconsciously hamper the driving experience of the car, and contribute towards false negativity about the reliability of these wonderfully engineered Porsches, and potentially effect their value in the long run.....it doesn't have to be that way.

I always like to say an educated decision is the best decision, so make sure that is what you do on this topic like any other. If there is anything we can do to help make that happen for you, please don't hesitate to give us a call

i do not know if there were factory radio delete .1RS. BUT you can remove radio and put the oem delete box in there. it looks finished. i'll see if i can find pic


driven 993RSCS, 993GT2 and 964RS in asia. i would take 964RS over 997RS
