*NEW* TPC Racing 991.1 Turbo S Build for Optima Batteries Street Car Invitational
Owner, aerospace engineer, and champion racer Mike Levitas will be piloting our TPC Racing/DSC Sport Porsche 991.1 Turbo S for the Optima Batteries Street Car Invitational of 2018! We stumbled upon this new opportunity back at SEMA a few months back with the idea of showcasing all that we have to offer at TPC Racing and DSC Sport on the track with a street car of our own. We wouldn’t sell our products to the public without the testing and quality control standards that we hold at TPC Racing to this day, so what better way to showcase our products then entering the street car challenge and pushing our capabilities above and beyond to perform.
When the 991 Turbo S was first delivered, we couldn’t help but adore the luxury of the interior with the street cars already aggressive look on 19 inch wheels with carbon ceramic brakes right from the start! Don’t forget the excitement over the forced induction system that will be immediately addressed with larger TPC Racing turbos VGT, TPC Racing intercoolers, TPC Racing tuner and ecu tune, TPC Racing BiMode HiFlo active exhaust, and more inspired from our 680Blitzkrieg turbo package.
The first time we put the 991 Turbo S on the lift, all the fluids were changed, and we took a good look of what we could remove and replace on the entire vehicle. The blueprint for this build was taking off and we had many different ideas of how we could develop the car.
Mike has been driving the 991 Turbo S on the road with the DSC Sport V3 controller with Dual-Mode exhaust control installed and already has been adjusting the calibration file for his driving style. Soon enough, we will be installing the Tractive Suspension damper set to the vehicle to further enhance the suspension setup along with the TPC Racing active sway bar kit, TPC Racing adjustable toe links, TPC Racing full monoball system including control arms and spherical bearings, and more that will be sitting on a set of new Forgeline wheels.
As the parts are coming in, we had an extensive amount of work and challenges ahead to prepare the 991 Turbo S for the season. So far, the TPC Racing GT2RSx carbon fiber body kit arrived that will be outfitted to the car including hood, fenders, quarter panels, deck lid, trunk, wing, front and rear bumper, front aero, and more to start our weight savings.
We are ecstatic for the opportunity to explore this new venture with Mike Levitas and his expertise that has the advantages in our favor! The livery from the 991 cup car will be matched for the livery on the 991 Turbo S after the body panel work has been complete! Be sure to stay tuned for updates and progress on this new program for the 991 Turbo S!

With progress made, we thought it was time for an update to keep everyone on their toes!
We stripped the Turbo S of its factory body work to fit the new GT2RSx carbon fiber package that was to be outfitted to the car.
All compatible factory wiring harnesses, lights, and hardware items were in need to be transferred to the new carbon fiber bodywork.
As we began fitment of the deck lid, we saw the need for modification for the ducting to the factory plenum as well as the carbon fiber rear deck cover needed to be slightly modified for factory mounting.
The bodywork for the rear was coming together nicely and the rear wing was ready to be fitted. While the rear bodywork was off, we took the time to fabricate larger intercooler pipes.
The front end was to be addressed and we proceeded with fitment of its new bumper, fenders, and aero. We were all very eager for the 991 Turbo S to see sunlight.
Great strides were made on the GT2RSx body work and it is ready to be wrapped today! Soon we will begin focus on the suspension with the install of major suspension components including TPC Racing active sway bar kit, TPC Racing adjustable toe links, TPC Racing full monoball system including control arms and spherical bearings, and Tractive Suspension dampers!
Stay tuned or subscribe to get the next update on the TPC Racing/DSC Sport Turbo S project for SEMA 2018 and Optima Batteries Street Car Invitational with its new graphics and more!
I think this is probably the best thread I've ever seen on Rennlist! I have not commented before...because I'm just speechless! I can't wait to see the final build specs, and then ultimately bring my car up to TPC Racing to get some portion of the final options.
I called these guys to ask about the DSC V3 box, and ended up talking to Mike Levitas for about 45 minutes about all of the options and setups possible for the 991 TTS. This guy knows suspensions!!
BEHOLD! The new TPC Racing/DSCsport race car build! Champion race car driver, shop owner, master aerospace engineer, and master technician Mike Levitas will be piloting our new race car build with a 2015 Porsche 991 911 Turbo S with PDK in next season’s OPTIMA Batteries Search for the Ultimate
Street Car Invitational series!
Over the next few months, we will see the 991 Turbo S transform as it becomes heavily modified with ALL that TPC Racing and DSCsport have to offer!
Levitas and his team as former Daytona 24hr champions in 2006 as well as former IMSA GT3 Gold Cup Challenge champions will look to make a forceful impact as the new competition. Levitas is no stranger to the podium as he has countless race victories and podium finishes which makes him and his team no
underdogs to the new race series. With the series approaching, look to find Levitas and his team in the TPC Racing/DSCsport 991 911 Turbo S at the following races below. The series will be TV broadcasted and the TV schedule will be posted as it becomes available.
The series schedule for 2018 is as follows:
March 17-18: Las Vegas Motor Speedway
April 14-15: NOLA Motorsports Park
June 2-3: National Corvette Museum Grand Course
July 7-8: Pikes Pike International Raceway
Aug 4-5: Barber Motorsports Park
September 15-16: Auto Club Speedway
October 6-7: Road America
Nov 3-4: OUSCI at Las Vegas Motor Speedway
We look forward to the new challenge and to be able to share our experience with the community!

The Turbo S AKA the TPC Racing GT2RSx was wrapped as we mentioned before to correspond with Mike Levitas’ #36 991 Cup Car livery. ENS Graphics did a great job on designing and wrapping the new fascia and corners of the Optima Batteries Street Car SEMA Build to give it a distinct look that won’t be mistaken for anything else.
At a certain point, we had to move the GT2RSx back into another suitable spot in order to use our alignment rack, so here is where they finished the vinyl wrap with our partners and sponsors for the season clearly labeled.
The next phase of the project was to focus on the suspension upgrades including upgrading to 991 C4 Tractive RT Suspension as well as upgrading the OEM bushings on the hub assemblies to Elephant racing monoball spherical bearings all around. We dropped the rear hub assemblies to focus on the new bushings installation first.
Here we have Mike and our lead mechanic Marco strategizing the next phase.
The goal for replacing the OEM bushings to spherical monoball bushings is to replace rubber with spherical bearings that hold precise camber and toe, eliminate flex from the suspension, and to make the car handling predictable and easier to drive fast.
The 991 Tractive RT Suspension is a direct OEM replacement to the factory PASM suspension. Tractive Suspension includes top of the line quality with Billet Aluminum monoball top plates, hats, and spring collars . First we put the Tractive RT damper on the shock dyno to get our base numbers for the current shock valving and determine if we were going to make any changes.
After the suspension numbers were recorded, we assembled the Tractive RT Suspension with the Billet Aluminum top plates, hats, and SWIFT springs. While the hub assemblies were out of the car, it was the perfect opportunity to install our TPC Racing Billet Aluminum thrust arm caster bushings.
Thanks to Forgeline, a sponsor of our Optima Batteries street car GT2RSx build, we were delighted to install a set of 19” Forgeline GA1R-CL in a gun metal gray finish sitting on Bridgestone Potenza RE-71R’s.
Final assembly of the suspension components were going smooth and soon we will be able to see the GT2RSx street car build sit on its new shoes and ready for a TPC Racing track-spec alignment.
Major thanks to our sponsor PFC Brakes, we got new PFC Brake GT3 Cup calipers for our GT2RSx to replace the OEM Porsche calipers and carbon ceramic rotors. The front calipers are 6-piston calipers while the rear calipers are 4-piston with amazing quality and finish. The Turbo S will be ready to stop on a dime during the Speed-Stop challenges throughout the Optima Batteries Street Car Challenge events with this incredible brake upgrade.
Our master mechanic had the task of adapting the new PFC Brake calipers with PFC Brake rotors. We mocked up the fitment with a set of used PFC rotors to get us thru the fitment process for the custom caliper brackets made in house until the new rotors arrived.
The final machining of the caliper brackets was done and the new PFC brake rotors were in! Stay tuned for availability of the TPC Racing Cup Car PFC Brake conversion kit for the 991 chassis!
As we moved forward with the project, it was time to engineer a bolt-in harness bar for our 991 and the market that would be easy for DIY and that would complement our RT4009W Racetech seats and 6-point Racetech harnesses. In the end, we have a great product to offer as you can see below and 100% manufactured in house. Contact us for availability on the TPC Racing 991 safety harness bar kits!
As an added bonus, we added a carbon fiber gurney flap to enhance the rear aero as well as cup car front fender flares to enhance the front. The carbon fiber gurney flap was modified to fit the curvature of the rear wing and the fender flares were modified from cup car parts we had at the shop.
We got the chance to install more front aero to the bumper before we felt the need for a photoshoot of our current progress in the sunlight.
After bedding the new brakes and test driving the GT2RSx for the first time with all of its new features, we did final prep for our first Optima Batteries Street Car Challenge event at NOLA Motorsports Park in New Orleans on April 14-15, 2018! Mike will be taking the GT2RSx to VIR this week to do some final testing before NOLA!
Be on the lookout for the next update on our build thread with first impressions, video highlights, NOLA Motorsports Park USCA event results, and more!
I caught up with Mike Levitas at VIR this week doing some shakedown with this car. Beautiful! I had just installed the TPC Racing DSCsport V3 box, which is transformational, and has it's own thread.
We’re at NOLA to test the TPC Racing/DSC Sport Porsche 991 GT2RSx in preparation for this weekend’s competition. Reigning 2017 OUSCI Champion Ken Thwaits stopped by to meet Mike and scope out our car. Should be an epic battle and a sure one to watch!!!
Be sure to stay subscribed for updates on the event results!
Is there a concise but detailed listing of all of the changes/mods to this car? I need to start working on a budget!! Also, what's the price for this whole package?
The GT2RSx has went on a diet! With ~ 70lbs in weight reduction, we removed the sunroof top and converted the USCA build to a slick top, removing the sunroof, tracking, and sunroof motor. While we had the chance, we removed the rear OEM Porsche window to replace it with the lightweight Porsche Motorsport GT3 cup rear window.
With an overall finish of 2nd at our first event and setting the Hot Lap pace at NOLA, we look forward to our next event and the opportunity to earn an invitation to the Las Vegas Final! Be sure to look out for the #36 GT2RSx and Mike Levitas at the next upcoming events! Speaking of which, the diet between events for the GT2RSx should be very beneficial!
As the season for the Optima Battery's USCA has come to a close at SEMA, we have plans this winter to develop the ultimate 991 RSx Blitzkrieg package for marginal HP gain on the GT2RSx which as some may know started as a 991.1 Turbo.
With the engine out, changes to the tune, addition of the TPC Racing intercooler kit, the charge Y-pipe, and a change from the restrictive OEM intake manifolds, look to see marginal gains the next time we rip the GT2RSx on the Dyno with the Dyno results.
We have been testing with changes to the tune before and now are putting more aftermarket performance products into this build to get the gains we are looking for to provide to the market. Less restriction for more airflow is the key!
With the perfect combination in parts and a perfected tune, in short time we will have the 991 RSx Blitzkrieg package by TPC Racing for the 991 Turbo which will be bullet proof for the consumer looking for a marginal gain without sacrificing reliability. Stay tuned for developments on the GT2RSx build as we continue our tinkering on developing the ultimate package for gains and for you!
Still awaiting a price list for all the options. (Also, better not try to test a TTS on that particular dyno. AWD?)
You are right, Mike looks like he is at peace and also thinking of his next move! The driveshaft to the front was removed for the purpose of the Dyno runs.
