http://www.planet-9.com/gallery/files/3/productphoto.jpg INTRODUCING THE FIRST 981 CAYMAN/BOXSTER TURBO KIT - TPC Racing 981 kit offers 100+ horsepower to the wheel!

Based on our wildly successful turbo kits for the 986/987 platforms, TPC Racing proudly introduces the first and only bolt-on turbo kit for the 981 Boxster/Cayman. Available for “S” and “non-S” models, The TPC Racing 981 Turbo Kit provides significant power increases to the Boxster/Cayman models that are well known for their superior mid-engine handling.

“It really is the ultimate drivers’ car,” Mike Levitas, Developer and Driver, exclaims. “With the added power from this kit, you can now crush the 911s on the straights while dominating them in corners thanks to the mid-engine handling characteristics of the Cayman and Boxster.”

Performance Tuning via Cobb Access Port
A very first for TPC turbo kits, the 981 Turbo Kit will feature full ECU tuning via the Cobb Tuning Accessport, in addition to Cobb Tuning options for the NA 981 with power increases for the base S model starting at 35HP.

As always, the 981 Turbo Kit makes use of a conservative .3 bar boost level to maintain engine longevity and reliability. Some owners of the TPC Racing 987 Turbo Kits have enjoyed over 100,000 miles on their TPC Cayman/Boxster turbo on street and track!

However, don’t be fooled by TPC’s focus on reliability. With no sacrifice on performance, the stage 1 kit provides 100+ horsepower to the wheel and 100+ ft-lb of torque, in addition to an aggressively throaty exhaust system!

Pricing & Availability
The TPC Racing 981 Turbo Kit is offered as a 100% bolt-on system with a starting price of $9,490.00. The kits can be ordered through TPC Racing or any affiliated dealer, which can be found at www.tpcracing.com. Each kit includes an ECU tune by developer Mike Levitas, so no additional tuning is necessary.

Yeah... everything I've read here on P9 tells me that these cars can't be tuned through the OBD port and that the only way to tune them is to send my ECU off to be modified in some mysterious process that frightens me a bit.

And then, just tossed in here like an afterthought, there's mention of a Cobb tuner for the 981. :D

^^ must be brand new for the 981, I didn't see it on their web site. Also the 'Porsche' versions, especially for the later models is not inexpensive...
 
#10 ·
Don't know what the price is for a Porsche, but for BMW it is $900. Assuming their claim of 35 hp is achieved (big if) then converting from Porsche to real dollars, they are practically giving it away.

This is a shot in the dark... but if someone buys the tuner, can they do multiple cars with it? In the GM world, there's a company that sells a thing called HP Tuners and they work on a credit system. You buy the programmer gizmo and then buy credits for each car you want to use it on.

Also... my apologies for sending the turbo announcement off on a tangent. We should start another thread to discuss the Cobb Accessport. :)

No intercooler option yet. We will be working on that down the road. For right now, we recommend our 2 gallon methanol injection system if you are in warm climates or use the car for track use. The methanol will not only offer a power gain and increase the octane level, but it will also lower the inlet air temperatures.

This is great news on every level! What can we expect from a stage 1 base 2.7 car? Is it still 100hp/ 100 tq?

Any info relating to tuning the 2.7?
 
#19 ·
Cobb confirmed that the tune they have for the 991 turbo is OBDII based. Same deal will be for the 981 I assume.

TPC, will Cobb be releasing the NA tunes direct or is this something they are working through you on? Timing?

Last I spoke with them they said the 981 was something they were considering but had not gotten too deep, but it was plausible based on the 001 turbo work.
 
#20 ·
I am not sure of the tunes that Cobb will be coming up with for the 981 NA car. For the 997TT we have had great success with the Accessport and have used our own tune and used the Accessport as the delivery tool. We will be doing the same with the 981 but still need time with that tune as we focused more on the turbo kit when we worked with creating a file. We will definitely keep everyone posted on when that will be available though!

Then it'll take us 5 years to know the results...

Am I the only one that has a "problem" with this whole concept :helpme:

When it was rumored that the new 981's would be turbo-4s I was tremendously upset given how much I love the sounds from my NA BS and really felt that there was no way a turbo-4 could ever hope to match the overall sound experience of a NA flat 6. There was NO WAY I was going to fall for that improved powerplant garbage.

And now I read about the opportunity to pick up an easy 100 hp and I'm drooling all over myself with anticipation. What happened to my resolve about the beautiful sounds of a non-turbo flat 6? What happened to my concerns about cooling and longevity? This is very, very bewieldering!!:confused:

Me too. I promised myself that I would not modify my next car given how much I've hacked up my current (and what I am going through right now with regards to an insurance claim on a wall excursion incident at the Nurburgring - but more on that once the case is settled), but this kit would make it tempting.

Hey all!

Awesome to see all of the interest in our tuning solution, the Accessport. We are indeed planning to add support for 981 vehicles in the future. While we do not currently have a hard release date, the plan is to have something available by the end of the year! Once we are closer to release, we'll definitely share more information regarding map availability, power gains, and pricing. We are also excited to work with TPC Racing to provide a comprehensive tuning solution for their recently released turbo kit.

The excitment in this thread is palpable, and I can understand that.

Me? I don't care if it offers 200 extra ponies and torques, and cost only 100 bucks to buy and install. The GTS is too fast as it is for street use, and the noise it makes when I can (briefly) put my foot down is something no added power can match.

Congratulations to TPC for making the kit, and for fellow P9ers looking to buy one. Me? I'm keeping mine like I intend on keeping my daughters (if I have any). Unmolested.

For the 2.7L, we are expecting a gain between 80 to 85whp and 80 lbs/ft torque.

In regards to issues, we have not had any. We are running a very low amount of boost and the car handles it extremely well!

As with all of our turbo kits here at TPC Racing, we always look for a smooth and increasing power band. At 2000 RPM all the way to redline the car is making power and you are never waiting for the turbo to come on.

The turbo kit will work great for both street and track. We have clients with 987 turbo kits who have over 100,000 turbo kit miles and drive the cars to work during the weeks and to the tracks for track events on the weekends. We design the system so that you can have a car that drives normal on the street but has a very smooth power delivery with a lot of power to offer.

For right now, we are asking that the first 5 or 10 cars be sent here for install. We are asking this because we want to make sure everything is going well with the install and also make sure that the tuning is perfect before the car leaves our facility. Once we have done enough of them to where we feel comfortable with how the installs have gone, we will start doing mail order and in house installations like we do for our 987 turbo kits.

Do you have any data on what installing turbo does to the gas mileage for normal driving?
 
#58 · (Edited)
I am sure Harris will provide an answer, but I have to ask what your definition of normal is? With all of the added HP you may find that you are stepping on it all the time! ;)

As we all will admit to from time to time we drive these cars "spiritedly", but when driven this way we have to acquiesce to the fact that mileage is not going to be great... that extra 100HP on demand comes from the fuel used.

I am sure that if you drive like there was an egg under the gas peddle the mileage wouldn't be much worse then before the modifications.

So the turbo kicks in at 2000 RPM? A clip of the tach when you floor it from a dead stop would be nice. Some clips of how it sounds/acts while driving around would be great too.

So people would need to either ship their car off (really expensive) or drive to you (big hassle). Looks like TPC racing is located in Maryland, like 1 hour north of Washington? How long does the install take and what are accommodations while waiting around the shop?

Jessup has the typical hotels that are on the Interstate. There is a diner across the street from the shop but if you stay too long "helping" out you might add a day to the previous three and a half day install times. It could be a wash to ship the car or drive and stay to do some DC sightseeing.

As for gas mileage, full boost comes on with WOT so in "normal" driving that might be only occasionally.

While there may not be a direct correlation between a turbo 3.4 and my hungrier 3.8, I get mpg in the low 20s during a generally steady 75ish highway cruise. When I'm into boost a bunch I'm in the high teens.
BTW, a TPC turbocharged 98x doesn't "kick in." It's the most seamless and linear turbo system I've driven. Likely because off boost its a high compression engine and the boost level is quite low.

I went to the TPC website and couldn't find any supporting information - basic information such as AFR management strategy, control of boost creep, target boost, general fuel management to ensure minimisation of early detonation etc. The absence of an intercooler......., type of turbo.....mass flow rates etc.

It would be good to see this supporting information so that consumers can make an informed decision - Just a thought
