Terryg Posted April 4, 2017 Report Share Posted April 4, 2017 I have just seen a thread on PH where a guy is given a loan car identical to his own and finds that it's markedly quicker than his own. There were a lot of theories as to why this may be but to mind the most likely was that the loan car had been driven hard, whereas his own car hadn't. Now then @John T @Loz987 I suspect you may both have something to do with my own baby revving much cleaner and quicker in the last few weeks than it did previously, so thank you (I think). I believe it's known as an "Italian tune up" on this site and I take it as proof positive that these cars absolutely have to be thrashed for their own good on a reasonable regular basis. Not terribly scientific but I think it's enough evidence to convince those who don't need much convicing Link to comment Share on other sites More sharing options...
Mr96er Posted April 4, 2017 Report Share Posted April 4, 2017 I'm sure a good "de-coking" can only be beneficial to your cars performance envelope. I am glad yours feels like she's cleaned her pipes! Let's get out again when you're local. Nowt like a bit of empirical evidence to get the nay Sayers tongues wagging! Link to comment Share on other sites More sharing options...

Terryg Posted April 4, 2017 Author Report Share Posted April 4, 2017 Blimey, just realised you two might start charging, Already got Russ emptying my account last thing I want is you guys at it too! If you have anything on the go the following weekend, I'll probably come out and play Link to comment Share on other sites More sharing options...
PaulQ Posted April 4, 2017 Report Share Posted April 4, 2017 If you can't "smell" that engine at the end of your run, then you didn't drive it hard enough ! Link to comment Share on other sites More sharing options...

Terryg Posted April 4, 2017 Author Report Share Posted April 4, 2017 Just now, Southy said: It should smell and make cracking/ticking noises My old air cooled bikes used to do that, not so certain about a water cooled car riven on the road.

topradio Posted April 4, 2017 Report Share Posted April 4, 2017 Love the way the car crackles as the insulation contracts after a spirited drive. I first noticed this on an MR2 MK2 that I owned in the mid nineties. Link to comment Share on other sites More sharing options...
edc Posted April 4, 2017 Report Share Posted April 4, 2017 This is easy to evidence. I've organised several dyno days for Boxsters and filled the day up with some other Porkers. It's quite clear that same car same engine can have a range in power output. Link to comment Share on other sites More sharing options...
Bike Loon Posted April 4, 2017 Report Share Posted April 4, 2017 It's worth turning the ignition on and leaving it for about a minute until you hear a click. This resets the throttle position sensor. As it "learns over time" when you reset it, it sharpens things up Link to comment Share on other sites More sharing options...

Not terribly scientific but I think it's enough evidence to convince those who don't need much convicing There is also a bike tuner who runs engines in when oil is warm with high and different load cases including max rpm sweeps. says it beds the piston rings in better... I plan on Italian tuning my Boxster S regularly once the coolant is up to temp... My Integra DC2 gets regular Italian tune ups.. as of course did my Lancia Integrale Evo when I owned that Link to comment Share on other sites More sharing options...

Anyone can speculate but with unknown history cars and owner profiles it's just a guess. You could argue for simple servicing, mileage, fuel, ECU adaptation etc. Also the engines are not blue printed. They are all built to within a tolerance range so inevitably there will be some variation in performance. Link to comment Share on other sites More sharing options...

I have closed off the PH thread but I think they were both 3000 milers and for that reason would have similar OPC service histories. I believe the variance in Porsche engines is controlled at the factory and anything significantly out of spec is rejected, but I take your point.

TV8 Posted April 4, 2017 Report Share Posted April 4, 2017 Haven't read the PH thread but equally as likely that the driver is less bothered about the loan car vs the owned car and uses it differently. Link to comment Share on other sites More sharing options...

Southy Posted April 5, 2017 Report Share Posted April 5, 2017 My car was having a service yesterday it could be just coincidence but they left the ignition on so the ecu reset. I normally get a follow up email asking how the car felt Link to comment Share on other sites More sharing options...
