Improving Cayman Gen 987.2 S Performance

[aeales123]

Hi Guys.

Basically I have a gorgeous 987 gen 2, 320ps Cayman. It is incredible in every way. I have a few thousand to spend so I figured I'd see what I could do to increase the power of my Cayman. I've got Celtic tuning coming to remap it soon which is only £300 and adds 15hp to it which is small but noticeable.

Does anyone know which products, exhausts etc to buy to increase the power slightly?

I don't want it to sound super loud but would love to get the hp to 350 or more if possible.

Cheers in advance.

If you're going to get it mapped. Then you should wait until you've done all the other changes you want first!!

Then get it custom mapped. That will make the best out of everything you've put on it. Rather than a generic ECU flash.

Hi there. Thanks for the reply. Do you know anywhere that does custom mapping?

[V800MJH]

Where are you located chap?

[aeales123]

I'm in Northamptonshire, in Corby. I'd like to try to get to 350+hp without doing enormous changes.

I think it's important to try and ignore numbers and focus on how the car will improve throughout the entire rev range. Peak power numbers are normally just pub bragging figures.

I'm afraid I can't help you with any Porsche specialists up in that area. (I'm in Surrey). But I know EFI Tuning are regarded as one of the best for custom mapping in the country, so you could contact them. Still a bit of a drive from you though mind.

If you want to spend some money on the car. I'd look into a new exhaust system, an IPD plenum and then once those are all sorted then get it custom mapped. But obviously liase with the mapper of choice before hand to see their suggestions too.

Hopefully MrD aka Porsche 911R will be along shortly and will be able to guide you as he has done his 987spyder. I believe 350hp is obtainable through changing manifolds , exhaust,plenum and throttle body then finally a remap

Speak to this Jens at EHRESMANN AUTOMOTIVE GMBH

He'll advise you on exactly what you need to do.

[aeales123]

Thanks so much for all your help. It would be amazing if anyone has any links to the components I need to buy and someone who could do the custom remap afterwards it would totally make my day. Any help is appreciated though.

I called Jens and he asked me to send him an email. Isn't he in Germany though? So will he sell me the parts and my local garage or specialist can fit them?

Personally id try and identify what youre actually looking for out of the car.
Getting power from these motors is a very expensive game in my opinion and if i were to start with a base car id probably look to spend my money elsewhere such as the chassis, tyres or tuition.

They will give you so much more than just an extra 30bhp.

My R has the following power upgrades:

EVOMS Intake
IPD Plenum
GT3 Throttle body
Fabspeed race headers with 200 cell cats.
Full Remus Ti exhaust
MASE Engineering mapping.

Makes anything from 345bhp to 375bhp depending on whos rollers its on, make of that what you will.
That to me is a huge amount of outlay to gain very little over the standard car.

Spend your money on some RSS Tarmac lower arms and some decent geometry setup aka Centre Gravity. You'll enjoy the most amazing steering and turn-in.
Genuine improvements you can enjoy all the time and at all speeds.

You make a really good point. I might see if I notice the difference with a basic £300 celtic tune. If I do I bet I'll really notice the other things. I can then remap it again.

£300 isn't too much to see if I really appreciate extra performance.

The car really is incredible, I've thought about selling it so many times but unless I want to spend 40-50k I'm not sure I'd be able to get a better car.

Not trying to pee on your chips mate, just want you to have realistic ideas for gains vs monies spent. I think you would be seriously lucky to see 15bhp from just a map. Reliastically more like 5bhp as a headline figure is probably more like it. Yet you may pick up some mid range torque here and there and maybe some improved drivability.
Alternatively, throw £300 quid at a track day and you'll see just how impressive your Cayman is in standard guise. You'll have more fun in a day than an extra 5bhp will provide all year and memories that last a lifetime.
Start adding some tuition to that and you'll improve the one component you'll take into every car you'll ever own/drive again

This is also worth a read

I'm worried about crashing but I may do a track day at some point to see how much fun they are.

Dont worry about crashing, youre not going out there to set a new lap record. Drive at your pace with some tuition. You'll be amazed at how much you benefit from having someone who knows what theyre doing tell you how to do it properly.

Porsche Club GB do Porsche only days and there are plenty of days just for novices like you who havent done it before.
Its only as fast as YOU make it

Bedford is on your doorstep, just go along, take a helmet and sign up for passenger laps to see how it all works out - it's only £10. People are generally friendly and will help out a novice with advice and passenger seat time.

That is cheap. We also have Rockingham speedway but soon it will be turned into car storage, lol.

don't remap one only it's pointless 10 bhp as best.

I would go Cobb as it's easy to use, Manifolds are a must there are 4 x 400 or 800cel cats in the manifolds so you are not gaining anything without swapping those out and that's £3.5k

At least with Cobb you can get a pro tune to tweak it.

I only have the vflow and the manifolds on the Spyder, I was told no need for the TB as it flows enough air anyway for a 3.4 lump its about 345bhp.

fully changes how the car feels though so great mod. would I go plenum and TB on the 987.2 car prob not.

I did change the TB on the 987.1 car as it was even smaller, but on the gen 2 it depends who you speak too, I think the GT4 has the same size and is a 3.8 and gives 400 bhp with tune only, so I don't see why it's needed on the 987.2 car at 350bhp.

any way Jens will give you a full run down what you can get but he don't use Cobb which is a shame.
I think 365BHP is the max with a full custom tune, TB and 99 ron fuel etc and keeping 2x 200 cats for MOT pass.

Cobb you can go back to stock any time and use it as a full monitor etc and sell it when you have finished with it.
