So here is the wrap up on the Cayman S with the TPC turbo kit... You can read the full install article with pics HERE.
We delivered the car to the customer who was very happy. We decided to add a Greddy Boost Controller to the unit and set the boost at 5psi. We hid the unit in the glove box which will allow the customer to change if necessary. Here in AZ it is very hot right now and we only have 91oct gas. The wastegate spring pressure would only make about 3.5psi so we we needed more boost to be on target. Since this is a daily driver, we never wanted to test with octane booster or race gas as that would not make sense in this case. We like to give our independent results. As you can see from the YouTube video above, this car is a blast to drive. The overall quality I would give is a 8 out of 10 as some aspects of the kit are just tough given the space and function to make a certain way. The only thing I would personally add to the kit is a blow off valve on the intercooler pipe to relieve the pressure between shifts. Even though it is only making 5psi, there is still a small amount of compressor surge. The installation is a long and tough one. 35hours is what is quoted, but get ready for about 50hours.
Now for the numbers... This car came to us with a couple of mods: Milltek exhaust, Milltek high flow cat headers, IPD Plenum, and REVO ECU Flash. This put the baseline at 256rwhp and 225ft/lbs of torque. Ambient temperature of about 100F. Our best dyno on 91oct and 5.5psi and 100F was 315rwhp as seen here. People doing the math will say that is only a 60HP gain? TPC shows a 150HP gain... Wait. Understand that this baseline had all the mods that most of you do now. TPC tested a BONE stock Cayman S using 93oct and ambient temperature of around 68F. Both the temperature and higher octane makes a HUGE HUGE difference in the cars performance. So there is 2 ways to look at this. First, the turbo kit gains 60HP over standard bolt on mods, not bad. If you look at another Cayman S baseline we did here, you will see that the car on our Mustang Dyno baselined at 218rwhp and 193ft/lbs of torque. Same ambient temp, same Cayman S, same dyno. So really we gained about 100rwhp and 100ft/lbs of torque with the TPC Turbo Kit for the Cayman S. Having had the TPC Supercharger on my own 996C2, we also gained 100rwhp on 91oct proven on our dyno.
So lets talk real world $$$ per horsepower so you can decide how to spend your money.
- Milltek Exhaust, Milltek Headers, IPD Plenum, REVO ECU Flash - $6786 + labor for 38rwhp/32ft/lbs
- Bone Stock Cayman S with TPC Turbo Kit including all Mods/Tuning - $10500 + labor for 100rwhp/100ft/lbs
