My Caymans S 341BHp and 300Ft/lbs Torque.
Discussion
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 ?

More details on the cup car parts please MrD.
I still struggle to believe the numbers... Were the runs done in the same gear, both corrected etc etc? I just didn't think the inlet/ exhaust were 'that' restrictive and the mapping so conservative...
I know it is possible, I just struggle to accept it I guess!?

How much has it cost in total including the cost of buying the Cayman itself? Im genuinely interested as the cayman/boxster engine isnt the strongest so im just curious to see if a 996 mk1/2 GT3 with a proper Porsche lump would of been a better basis to start off with.

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.

You'll always get your fair share of doubts and doubters about such matters mate, it's human nature. From what I've heard you did a fine job minimising the differences between the two tests and you have the right to be chuffed with the results.
Speaking from the viewpoint of someone who has actually driven the car in question (since the work was carried out) I can confirm that it picks up far better in the 3,000rpm dead zone than my car (which has the Remus exhaust but none of the other kit) and I for one find that justification enough, regardless of bhp gains.
Good work fella

hmmm.. its no elise though is it 
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.

Actually their site still says 10.8 for the Elise on this link - a lot faster than their 11.97 website claim for the Exige PP lol!

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.
