I'm a bit suprised that you have that racing gear box sound due to the changed flywheel.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

12 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

Hi Guys I tested the acceleration of my Cayman 3.8s today. I have taken the time from 40km/h to 140km/h for a Cayman S, Carrera 2S, and 997tt and compared it with my Cayman 3.8s. The other cars were tested by Car magazine. My Cayman has the stock 997s software and exhaust with 600km on the engine. The only modifications are headers, de-snork and light weight flywheel. -------------------3rd-----4th------5th------6th (gear) 997 tt-------------6.9------9.0-----12.0-----17.6 Cayman 3.8s-----9.4-----12.2----15.4------20.3 997s-------------10.1-----13.4----17.3------24.5 Cayman S-------11.2-----15.3-----21.3------24.6 After running in the engine I will test it again with an aftermarket exhaust. Cheers Herman

POST 2Original post

Very nice. I'd like to see a 997 GT3 thrown in the mix. Thanks.

POST 4Original post

Hi Ken I do not know how Car magazine test their car. I used my GPS the check that 40km/h is 40 km/h on my car and 142km/h on my car was 140 on my GPS. I cuised at 40 and on a level road in 3rd, 4th, 5th and 6th gear and used my Sports Chrone to measure the time it took to reach 142 km/h. I did this four times per gear and the times were very close each time. We have a Porsche day on 6 May and will then post my 1/4 mile results. Car magazine is currently testing a GT3 RS. The results should be out next month. Cheers Herman

POST 5Original post

Did you use the figure on the speedo or the GPS?? There is quite a bit of "damping" built into the speedo reading, so you will actual hit 140 a lot sooner than the display reads 140kph. Magazines would always use a GPS-based data-logger which would give much more accurate results. The good news is, Herman, that correct measurement should only improve your figures Mmmm, me too would like to see the 997 GT3 figures thrown in there as well. Thanks for the continued feedback from your very interesting project. Jack

Herman, Would you please give me sourcing info on your light flywheel. Brand and specs if you have them. thanks! -G

POST 7Original post

Aasco Light Weight Flywheel Hi Greg My friend Randy owns Aasco Performance in LA. He makes a one piece aluminum flywheel that weighs about 16lbs. He gave me Sachs clutch plate with springs as the standard disc is solid. The price was $850 for the LWF and $500 for the clutch plate. With this single mass flywheel you get a lot of gearbox clatter up to 2800 rpm. It sounds the same as a 997GT3RS as it also has a single mass LWF. Cheers Herman

Herman, do you also have solid motor and trans mounts? I'm a bit suprised that you have that racing gear box sound due to the changed flywheel.

who did your conversion i am currently communicating with Farnbacher Loles as they seem to be the most reputable source here in the states.How many HP out of your 3.8, F-L says 400 hp out of their revo tuned conversion. K-Man Are they a site sponsor and if so is there something I should say or do to get you credit for the 50K or so i am going to spend with them?
