Hi All

Just wondering what the general consensus is on performance mods on the 997 3.8s.

Which ones are worth it??

If you haven't got it already, and to remain with OEM parts, perhaps a PSE sports exhaust.

Having only owned my 911 C2S Gen 2 since August of last year, I'm in no way knowledgeable enough with these cars to talk about technical upgrades. However, I have put just over 9700 miles on my car since purchasing it so here’s my thoughts on upgrades I’m looking at.

The first one is driver tuition. I’m pretty sure that paying a driver who’s far more skilled than I am at getting the best out of a 997 to show me how to get the best out of it will be the best performance upgrade that I can ever invest in.

I go to Spa Francorchamps every August and witness the same thing every year and that’s guy’s in their 30’s driving stripped out Mazda MX5’s and old Honda Civics leaving guys in their 60’s who are driving 100-200k supercars for dead.

So driver training is top of my list.

Secondly its wheels and to be more specific, the 19’s that came with the car and are scheduled to go back on after Easter. I’m running OEM 18’s with winder tyres at the moment and while comparing winter tyres to summer tyres is like comparing apples and oranges, 18’s and tyres with a little bit more rubber has transformed the feel of the car.

I’m not able to tell you technically why it feels so much more planted on the road but what I can say is that I’m seriously considering not moving back up to 19’s. I drives so much better on 18’s.

Yes, the trend may well be for bigger and bigger wheels and my car does sit better on 19’s but it can’t be all about the look, can it?

So driver training and wheel choice based on driving feel more than looks would be my consideration.

Wow

Driver training never even entered my mind.

How much does that cost? Sounds quite fun.

I was looking at performance mods? But driver training is an interesting shout.

As far as performance mods I’m assuming the norm.

Exhaust, air filter, map etc

I’ve already fitted new switchable back boxes and BMC filter. Just wondering what the general consensus was?

You have to throw serious cash at the situation to get major gains in performace since the car is already so well engineered.

Depends what you want. For me I have a cab as well and I think the car is plenty fast enough for the road, so have been focusing on the visceral upgrades:

GUNDO exhaust hack for the noise
Michelin PS4S tyres - has really improved handling, NVH, feel etc..

Looking at short shift kit and maybe the PASM piggy back box which turns the passive suspension into active suspension (sounds really interesting to me, not sure if it’s name but it’s about £1500!), also interested in lowering springs and spacers for improved stance.

Cold air induction I’ve read doesn’t add any ponies unless you lay down some serious cash on motorsport stuff, but interesting in making the induction noise louder for when the roof is off.

Depends what you are chasing. Decide that and there are loads of options.

If you haven’t done much track time then that’s a good place to start.

I’d suggest buying something faster.

I did look at a 996 turbo but they appear to have risen in price £2/5k in the last 2 years.

I think I missed the boat on that one😩

With a Turbo you can at least tune and get real gains.

With the NA cars there’s all this talk of improved throttle response, better torque curve etc, most of which is imagined.

Imagined?

I would have thought there would be small improvements? I know it won’t be the same as turbo cars but I would like to think I could get another 20hp out the car??

Sounds like you don’t think so on a NA car?

As above, the NA cars are fairly much at the limit of tuning as they came out of the factory. You can make them sound different and ride different but will really struggle to have any real effect on the actual power output. Turbo’s however have a lot more room for play.

To be honest I’m really surprised.

I would have thought there would be something more than improved sound?

Free flowing exhaust, air filters, Re maps etc, most of these do talk about small increases, both of the above suggest not. I’ve videos with rolling roads before and after on an exhaust system. Gains of 10/20hp appears possible?

Oh well, just have to buy that turbo. 😂🤣

Got are the days of restrictive exhausts and air filters a la Max Power tuning. The 911 is a seriously well engineered thing and any gains will be marginal. Not to say they aren’t possible I think there was an x51 performance package from factory with some improvements so they are in the Carrera package, but what is 20bhp?! Like less than 10% gain, would you ever feel that on the road? Better to make it sound and feel faster, or be able to drive it faster. Either that or sell it and get a machine with more horses if that’s what you are chasing.

Just think it’s not worth the money for the gains personally, not like a turbo car where you can remap and get an instant 20% gain.

Just bear in mind the so called gain of 10hp or 20 hp can be achieved by running on a cold damp day as against a hot dry day, the temperature of the cars engine, altitude, new oil etc etc not anything that is guaranteed repeatable.
