Well as some of you know I set out to tune the Cayman S a little.

I feel the Cayman is a better car all round than the 911 so a good place to start.

I also think atm the Cayman S is a great buy and a good step up from my old Exige for a usable every day road sports car.

In standard form it Dyno at 292Bhp and about 245 Ft/lbs torque, there was also a nasty dead spot (which all Caymans have) at the 3200Rpm range.

I looked long and hard on what to do, as we all know money is tight and getting more Bhp from a Porsche can be expensive. So I turned my eye to what the USA were doing to these cars and was amazed at some of the claims.

So I set out to test the USA kit over here in the UK and have taken many pictures and readings before and after of my car and what has been done. ALso with live data with my laptop using Motronic ECU on all runs.

I must say I am very pleased with the out come.
The car drives fantastic, the power is smooth in the whole rev range and also NO dead spots which you can feel while driving.

My results are 341Bhp and 300 Ft/lbs Torque
(I am even sure I might have a little more as intake temps were a little high on test day)
ALso my 60-100Mph time is down by 1 second on My GPS data logger and mid range punch/power is to hand every where. No lag or heat soke here

Many said impossible cannot be done on a N/A car
I even thought the claims in the USA were over rated myself.

But I have done it from start to finish and I have the results
I hope this will help people in the UK to know what can be done for little money, and infact we are having a Cayman S tuning party this weekend and tuning up 5 more Caymans, so any guys going from here can expect great results ;-)

Scott who has worked with Porsche for over 16 years seems the master of the Porsche ECU and has made the Cayman one of the greats.

It even gives more Mpg which can only be a good thing with petrol on the way back up.

Total cost for the tuning items was only £2100 and can only be great value imho.
(These price have gone up as the £ is not so great and his price has also gone up)

Porsche warranty lol

As for the map its invisable and the only Porsche map to be invisable
I have a few maps for my car and it can go back to stock any time.

All other parts are Porsche GT3 Cup car items (bar the exhaust system)

So no 3rd party parts used, all Porsche items in the engine bay.

Now do you think Porsche held back the Cayman to save 911 face ?

Will post all graphs on my web site

lol at doubters, I am just a guy testing stuff as I did not think the gains were possible.

Dyno were the same in every way, I even made sure the same guy did it which took some doing.

yes corrected by the dyno for flywheel as i did not take the engine out :-)the BHp at the wheels are 240 before 283BHp after.
Tyre pressure were set just before the run both times and also the same fuel has been used all through the tests which was Shell V max.

hmmm.. its no elise though is it frown
No thank goodness :-)I have yet to see any proven Elise times As Lotus always state 9.9 seconds to a ton and 2 seconds faster round their track lol.

As for Location of the Dyno, what does that matter, as long as the tests were done the same before and after it shows the gain on the same unit.

If any Dyno owners want to do a free Dyno and pay me travel costs on the car then PM me.
But as the car will have not been done on that Dyno when standard it will not prove much.

Put it this way the people I used do not sell or tune Porsche's as I would have never got that past you and that would have been a fix aswell.

Lets not get into Lotus bashing ( i owned 2 )

But they never hit the quoted times and 9.9 was the Exige S quoted time on launch lol when not even the Cup260 can do that time.

Another reason why i sold my Exige and did not S/C it 5k is not good value and the figures stink, all these quoted Bhp/Ton figures but no real results
:-(

ALso forced induction cars start to eat up the fuel and suffer heat soke My Cayman does more Mpg now :-)and no lag or heat soke problems.

Anyway lets keep this thread on a Porsche topic, Lotus boys have their own forum to talk figures. And they still make the best track day toys imho.(after a few mods)

I got told to go away when I questioned Lotus times on the Lotus Piston heads forum, so I did :-p

So I find it odd to talk about Lotus cars here on a Proven Cayman tuning thread.

As for SELOC that is the new Porsche forum I thought :-)

All the shootout data has been deleted from the bottom of the graph, makes me suspicious immiditately.
yes that was my comment on his other thread too. What's going on with that?

The other point is that Manthey and Cargraphic don't seem to think they can get this power with their mods?
That's why I did not go with any of those Porsche tuners :-)

I choose the best person in the world imho to get my map from, He does tuning and engine rebuild of the 996/997 Cup GT cars and has been doing Porsche cars for 16 years, Knows the Porsche ECU better than any one imho.

My plots will all be on my web site un edited for all to see, but as i have about 8 bits of paper i just showed you this one, but rest assured every thing was the same, If any thing my car has more than that Bhp as I did the last run late in the afternoon and temps were very hot, My car even felt slower that day, it was 20oc after all, and we all know cold air is best, even my intake temps were 10 oc higher for that run. I have been using my car today and tonight its realy shifting and temps are 12 Oc outside atm.

Other people have 360+Bhp with the same mods + Manafold :-)

As for 997 C2S I think my car would be faster no contest (non DFi model)
Shame no UK tuners are doing good value tuning work and we have to do tuning parties and import the best stuff on our own.

I think 10 or so Caymans are using these mods in the UK now and growing every time some one has a go in one. We( when i say we I mean I had a beer and BBQ and watched other people work) did another one today and we also took two more people out in both cars and now they want it doing also :-)

All very interesting stuff.

I have no idea how Dynos work and I have no real interest in BHp figures.
My car was not dyno tuned the map is an adaptive learning map which matchs my mods.
The lotus Car tuners proves dyno results are pointless with massive Bhp/Ton figures but no fast times to back them up.

But People always ask for them so I did some at my own cost at a non Porsche tuning Dyno rig which is a well know unit in the UK.

All I can do is test my car in every way possable before I had it tuned and then try and do the same tests after.

I have never talked about Porsche figures all I have talked about was what MY car did on the dyno before and after. And my Vbox runs which I need to do again as I have now got a better map. which picks up quicker at lower revs.
So take correction out at the flywheel etc and just show the at the wheels figures these were 240Bhp before and 283Bhp after.

The 1 second faster is a real figure and you can feel it, the other great thing is NO dead spot at 3000Rpm this always bugged me and now the power is just so smooth any where in the range, So driving it just feels much nicer.

But the vbox is the best thing as it just shows the car faster every where, I am trying to learn the graph plotting feature so people will be able to see what times I got in runs like 30-70Mph runs
and all the times inbetween, I have done lots of tests and will do many more, I have never liked Dyno figures but I love vbox speed times as you get to see real on the road gains which is some thing no tuners ever show.

Calling Surry rolling road and Charlie.

Did you not RR the "Yellow peril" to 360+Bhp ?

I am sure karel used you to test his car which was the 1st one done in the UK.

"I just don't believe that the top German tuners would leave that much power on the table if it was actually real and available. Why would they?

Who is this guy that did your mapping?"
End quote

German tuners can have all the skill in the world but if they don't have Scott Slauson then they cannot get the best out of the ECU imho which is why i choose his system.

Even Scotts software uploads quicker than the factory can do it, he sure does know about Porsche ECU's.

I know nothing about Surry RR . mine was done at Thorney Motor Sport.

As for Charlie @ surry RR I don't think he has tested the yellow car in its current form so I have just been told.


There are many Quotes about Scott here are some good ones.

"Softronic’s owner and tuner Scott Slauson is considered to be the leading authority in Porsche tuning by many. With over 30 years in fuel injection experience, Softronic is the lead company in Porsche race car data checking. Softronic sets the ground for which there is no comparison in automotive technologies"


"Softronic has been doing Porsche Performance for 20+ years. As the former PCA technical advisor and now working with Porsche Motorsports and even well known race teams for data checking and tuning, Scott Slauson brings a convenient, well thought out, and proven form of ECU Tuning to Porsche"

"Softronics was created and is run by Scott Slauson. You may recognize his name from the Porsche Club of America and/or the Panorama magazine. Scott has been on the PCA technical committee since about 2001, specializing and sharing his expertise on the 986, 987 and Carrera GT platforms. Scott has been turning wrenches on Porsches for a long time and is recognized as one of the worlds most qualified experts on Porsche DME software."

I think people are happy with Scotts work :-)

I do have some faster times I will dig them out.

thing is above 100Mph you start to need big Hp to over come drag.
I have been next to a 997 GT3 but after 125Mph it just flew by, but then it does have 415Bhp.

I am getting NO discount or any finders fee, btw
I did this as I was gob smaked at the claims and did this to prove them wrong, but I found out that they are right and the car is amazing.

here is the lastest quote from the last one which was tuned posted today on the Cayman Forum

"Well, what does it feel like? Fantastic, fabulous, punchy, more grunt and yet still smooth, rich and full powerband with more everywhere throughout - not just at the top-end. Exactly what I was hoping for having driven Karel's Yellow Peril a few weeks ago.

I hadn't noticed how much the dip around 3500rpm that my car had previously was affecting my driving experience. Now there is power and torque available on tap and overall it feels like a very well sorted engine map - spot on.
"

some people do not care about figures, they drive a tuned car and just want the same.

quote "stock 100-200kph is about 14s, if yours has 340 real hp it should come in under 11s "


Well it's not going to do under 11 seconds is it when 385Bhp cars are only just in 11's and GT3 are 11.3 !!!
Must be the extra drag on the Boxster slowing it down above 100Mph

these are some figurers I have spent time collecting 4 for each car than average them out 100kph to 200kph.

14.7 Boxster 3.4 RS60 with 305 Bhp
14.1 Cayman S 295 gen 1
13.5 Cayman S techart 310Bhp
13.5 Cayman S PDK 320Bhp
13.2 Cayman S Weland 320Bhp
11.9 Cayman S Techart 385 Bhp
11.1 Cayman S Weland 385Bhp

other faster Porsche
12.8 997 C2 325Bhp
12.3 997 C2 345Bhp PDK
11.5 997 C2s 355Bhp
11.5 997 C2s 385Bhp PDK ( ok which is right cannot be the same time as the old 355BHp car)
11.4 997 C2s 385BHp power pack car
11.3 GT3 Mk1 360Bhp

So some interesting times there.

Scott gets them from Porsche, but atm he gets all stock available as when you see the date stamp these thing are 1 to 2 months old max.
he also mods the chip inside the unit. so i dont think any one else can get the part.

Here is a pic of both parts together, plenum and throttle body

Costs are in a kit which he does just for the Cayman with the map to match
If you dont by the kit from him he will not sell you a map.

Ofcourse you can buy the 2 items as a stock product one of them is £350 i forget the other price.

As for Vmax stuff that's all down to drag,wind etc I have a bigger rear spoiler on mine so will not be vmaxing at 170Mph.

I know the techart gt3 Style wing for the cayman loses 20Mph of top speed as an example.

But Vmax is a whole new ball game and not some thing i am interested in.
at 7000Rpm the max speed of a Cayman S is is 172Mph

Yes the gt3 is a nice car bar it's 10 years old.

I don't track the Cayman it's just a every day road car for me
Some people just like the Cayman for what it is, all I am saying is if you want/or already have a Cayman then spending 2k on it does transform it.

Forget about dyno results If you own or are in the market for a Cayman do what I and afew other have done, you will love it.

you cannot put a old car V a new car. ffs

A 3 year old Cayman is 25k a nice mk2 996 GT3 is 42k so not even in the same ball park cost wise.

Why are you on this thread again ?

If you want a GT3 V a new Cayman thread start one and fook off mine :-p

A picture = 1000 words

I think the Cayman is a great looking car,
I need to get computers in it.
I like to go on holiday in it.
I like having something which is not just another off the peg car.
When I got it GT3's were 15k more expensive and still are.
I don't do track days any more. So no need for my Exige.
I like being faster than 911's in the ""poor mans Porsche"" :-p
It's a hobby and a one off looking car.

Yes I would not mind a GT3 for a laugh but atm it would not fit my needs.


As for this line "if you want a good handling fast porsche buy the real deal"

er I bought the best handling car Porsche make ;-)

No other reason to post a 150k+ 15 year old car on a Cayman 25k tuning thread.
