The GT4 gives us sports car and track enthusiasts much to celebrate about. We love working on GT4's and watching our customers get sync'ed to their cars as we provide setup support along the way. Here's to the GT4 and the hardworking TPC Racing crew- Got 4 tickets for Pick 4, with 4 4's for working on GT4's on 4 consecutive Thursdays.
Here are some photos from our shop to celebrate the Glorious GT4 and all the lovely colors we have seen and yet to see, and the different variations of setup/prep that's far from mundane!
And this gent takes the prize for the best key chain!
Cool pics! Open up a facility on the West Coast! Orange county works for me.
Thanks! I think there're plenty of good shops in Cali. Some of them we have raced against in pro racing and found to be formidable and very worthy competitors. If you come through the Washington DC/Baltimore area feel free to drop in. :-)
My 'friend' who already has headers needs to come by for the Cobb AP, IPD plenum/gt3 TB, and tune. Are these available currently?
Please let your "friend" know that they are indeed available. COBB AP with TPC custom map is one of our most popular products. Completely eliminates the power dip in mid-range and adds ~20whp peak gain. We go through 10 units at a time faster than milk expires.
While we can certainly do in-house dyno custom tune to his plenum/TB, here's a sneak of what we're working on- Later this Fall we'll offer a package that features our CNC billet aluminum adapter plates to adapt OEM 991 GT3 intake manifold and TB on any 9A1-type 3.8L engine. The OEM 991 complete intake manifolds have massive runners, with custom COBB AP mapping will seriously rip! This has been project that we've been wanting to do on our shop's GT4 since last Fall but our suspension development program, customer support, and IMSA racing effort has left us no spare time. Now that IMSA racing season is over we will complete this GT4 power package. We installed this package in a 997.2 Carrera S 3.8, the 991 GT3 intake manifold and TB extended the powerband so much it was insane! Needless to say, we are an advocate of some aftermarket go fast parts as we feel that some OEM parts don't satistfy our usage needs but whenever possible we also take advantage of factory/Motorsport engineering from higher model in the lineup to increase performance This package is a perfect example. We are psyched about this development program and we will be offering the finished package along side with the elite BGB Motorsports team. Here's are some sneak photos.
Bump! Updates on GT3 manifold swap! How much is the GT3 manifold? Install time?
Thanks for the bump. We have our shop's GT4 and 3 local customer cars lined up to do this. We have scheduled for the first installation in December. We will be documenting the installation and results and provide installation time and cost of the package at that time.

I am afraid the answer for this question is I don't know. We are using OEM 991 GT3 manifolds, plenum and throttle body to take advantage of the factory engineered complete intake manifold. At this time we have no plans to deviate from the OEM 991 GT3 parts.
Please ask Mike when he plans to supercharge the GT4...
I still remember the red supercharged 993. It was only one of the most satisfying Porsches I have ever driven. Instant and utterly predictable torque, yet didn't feel supercharged and revved out. Felt like an 8.0-liter flat six with a lightweight flywheel.
My friend will hold off on his IPD Plenum purchase
My "friend", who has been away from RL for some time now, just saw this and can't wait to get his hands on this mod....was about to pull the trigger on the IPD mod but will hold to see the results and some info on the installation. Would be a very nice Christmas present!
