I had that same question ..WHY?
well first I researched this TPC Racing Co as I personally had never heard of them and I wanted to see for myself who and what they were all about so I went to their site TPC Racing and researched the history of the company as well as E-mailing forum members that currently had a TPC on their Cayman/Boxster. If I am going to put a Turbo on a car I already have a ton of money in to then I want precision quality and Reputation. My research concluded this was then place I wanted to do business with ,THE BEST ! these guys have a LONG list of references ,Top Notch
Then It was a simple dollar paid per HP increase If the Turbo without the intercooloer can add 100 hp for $7500 you have More Power then a Cayman S@295 and a 2.7 turbo = 345 hp estimate
With the TPC turbo including the intercooler and front radiator parts are 10K but an estimate of HP increase is @ 150 so a 2.7 would have just under 400HP!! .these are all just estimates as we still dont know what they will be until there is a completed 2.7 TPC TURBO finished.
Then IMO you have a Real Mean Machine A Dream machine
A car you keep for Life
Not quite a GTt-3 killer, but close ,and far faster then an S model or 911 .

FYI - I do not work for or personally have any affiliation with TPC RACING .

 

thanks. the issues you considered are similar to the things i am considering.

before i start sending my inquiries to tpc, i have one more question: was the atp:l low pressure turbo kit that you selected specifically engineered/designed for the 2.7l motor that we have? or was it intended for the 3.4l motor, but you will have to adapt it for the 2.7l?

i recall seeing a copy of an email from tom chan of tpc dated december 21, 2007, that indicated that the $10,000 tpc turbo kit is for the cayman s with the 3.4l engine and 6-spd gearbox. however, tom also indicated that tpc will develop versions for the tiptronic gearbox, 2.7l engine, and 3.8l engine.

 

I dont know about the tiptronic gearbox, 2.7l engine, and 3.8l engine in regards to the TPC . I have a 2.7 5 speed and they will be using the same unit I believe .I think the Turbo installation and software tuning procedure needed to complete the project are pretty similar for the 2.7 and 3.4 ,maybe Casey will chime in and have an answer for you ?

 

We have recently finished development on the non-intercooled version which is optimal for the tip car as you do not have to add an aux trans cooler. Our installer in Hawaii has already installed one with and his client is extremely happy!

We finished the fitment with the 986tip last week and you can find a thread on it here

https://www.6speedonline.com/forums/...ing-turbo.html

Will have some video of it this coming week!

Let me know if i can answer anything else.

 

casey, thanks for your response. my apologies, but it appears that i have been imprecise.

i have a 2.7 5-spd (non-"s" model) and after seeing porschepet's post that he was going to have the atp:l low pressure turbo system installed on his 2.7, i became quite interested. tpc's website appears to indicate that the 987 cayman s turbo kit is for the 3.4 engine ("Turn your stock CaymanS into a GT3 killer with the 485HP TPCRacing CaymanS Turbo Kit"). however, as i don't have the "s" model, it didn't appear that the tpcracing caymans turbo kit was for my car.

however, i recall seeing a copy of an e-mail (i believe it was on pelican forums) from tom chan indicating that tpc was developing a turbo system for the 2.7 engine in the non-"s". i presumed that the low pressure turbo system that porschepet is planning to have installed in his non-"s" (2.7) was the system referenced in tom's december 2007 email. however, tpc's website does not indicate that the low pressure system was engineered for the 2.7 (non-"s"). the website merely indicates that the low pressure system is a cost effective way of turboing 986 and 987 models (non-intercooled, ~4.5psi, an additional ~100hp at the drive wheels).

was the atp:l low pressure turbo system that porschepet is installing in his 2.7 engineered for the 2.7 (non-"s")? or was the system designed for the 3.4 engine (the "s" model) and has to be adapted/modified for the 2.7?

one other thing, can you identify your installer in hawaii?

 

This does sound interesting with the 2.7. It could make a great price point for power.

--The system works just fine. The only issue is adjusting the tuning(which is not a big concern) as the majority of the pieces bolt on w/o issue. We dont advertise the system on the smaller engines, simply because we have not gotten to a place where we have had enough demand for it to create the tooling and modifying our jigs. Porschepet's car will be the first m97 2.7L we have completed. He is having the system installed at a very good installer, one who we trust.

--We are in the final stages of releasing the ATP:L system for the masses. It will fit on mostly all m96 and m97 blocks, with possibly only a small bit of fabrication. Whether it is a 2.5, 2.7, 3.2 or 3.4(excluding dfi, for now), we have options, both in Manual and Auto.

--As i stated before, it is roughly the same design, some of our piping needs to be adjusted, but before we send the system out we will test fit on a local car.

-Chris has already installed one and did a fantastic job. It was on a 3.4L Auto cayman(non-intercooled) and he and the client are extremely happy with the results.


This latest boxster, that we just finished has the newest version of the lower pressure kit. Pretty trick and i will get some video up as soon as I have a moment to finish editing and uploading it!

shoot me an email to cparkin@tpcracing.net and I can answer further questions there.

 

casey, thanks for your response. i also received your pm.

i'm in the early stage of researching power upgrades, with the tpc low pressure turbo system currently at the top of the list. i'm still probably several months from pulling the trigger on such an upgrade. i would like to wait until porschepet has put enough miles on his upgrade to hear what he likes and what, if anything i should lookout for (be prepared for).

also, i'm planning to first have a guard transmission tbd for the 5-spd (when they come out, which according to matt monson, should be in the near future) installed, which is part of the reason for my timetable (the several months wait before i pull the trigger on the tpc system...in this economy, i can't afford to do it all at once, i'll need to have it done in increments).

i'll be anxiously waiting to see porschepet's reviews of his upgrade over the upcoming miles of driving that i presume he will do.

i'll be in contact with you when i decide to pull the trigger. until then, in addition to reviewing porschepet's review of his upgrade, i'll continue to periodically visit tpc's website for further updates.

 

i just pulled the trigger on the system for my 2.7l cayman. thanks to casey for his assistance and patients.

it'll take about 2 weeks for TPC to build my system, but they'll try to finish it sooner. then it'll have to be shipped to the TPC authorized installer in honolulu (another week or so?). the installer indicated that it'll take between 1 and 2 weeks to complete the installation (he's already installed the same system on a 3.4l tip cayman). that means that in about 5 weeks i'll have a "new" car!

 

Whats the price for the system for the 2.7 and what would a shop in LA charge for the install??

 

check the TPC Racing website for their prices.

i believe it is estimated to take about 20 hours for the installation. the cost would then be whatever the hourly rate the shop charges x 20. the shop doing my installation charges $90/hr.

 

You can ask Casey at TPC Racing for the nearest Install shop ,I am sure there are several within striking distance of Compton . RSS or Sharkwerks possibly ?

 

TPC's website also lists their authorized installers.

 

I would recommend GMG or BBI, Call betim or Fabryce.

Casey

 

Wow 2 Really top notch shops .. Must be cool to live in La
