This stunning White on Red 991 Turbo just got dropped off here at Fabspeed Motorsport HQ for baseline testing and product development! We see a huge amount of potential here just after our initial observations and getting the car up in the air

We are excited to become a part of the rapidly growing 991 Turbo and 991 GT3 community

Stay tuned for exciting Photos, Videos and product information in the weeks to come!

Look at those headers and massive cats!!

Looking forward to the power gains!

I had the car on the dyno last night, and this car did not disappoint.

I google searched 991 Turbo Dyno because I could not believe, at first, how much torque it made.

Remember these things (the non Turbo S cars) are rated at 524 ft. lbs from the factory, with Sport Chrono/overboost.

Porsche is always conservative. I bet in 100 degree heat the thing will still make 524 ft. lbs.

The only graph I found was Champions, which starts at 3000 - I found that rather odd for this car. They also dyno'ed in 4th gear, which is not the closest ratio to 1:1 on the 7spd PDK cars. On a Mustang dyno they recorded 456 ft. lbs of torque to the rear wheels. Judging by the graph, the gear they chose, and their location (Florida), my guess is that a combination of the hotter weather, high rpm start point, and higher gear ratio did not allow the car to build boost quick enough to make the torque that we did at Fabspeed on our AWD Dynojet. I would also be curious to know how they were getting their rpm signal - if it was calculated based off drum speed, or if they were actually grabbing it from a signal from the car. For those that do not know much about dyno's, Mustang dynos allow you to calculate vehicle rpm based on wheel speed - you must input such things as gear ratio, final drive ratio, and tire circumference, and the software back-calculates rpm, and then calculates torque from this. It is far from the most accurate way, but some of these newer cars are a pain to get an accurate tach signal from, especially Porsches that have very difficult coil pack access. We use an EZ-RPM module that receives pulses from the alternator.

Anyway, onto the good stuff. Below is our graph from a bone stock 991 Turbo non S. We did multiple runs, and did 2 4th gear pulls as well as 5th gear pulls. One of the lines below (runfile 6) was done in normal mode. Very impressive numbers. Very similar graphs to the 997.2 Turbo S cars that we've dyno'ed.

Run conditions:
All runs were performed with high powered Bapro fans in front (22,000 CFM)

One Minuteman Rapidair Carpet blower in each intercooler duct (60 mph velocity but not a lot of CFM)

Water misting in each intercooler duct in order to prevent heat soak and repeatedly/accurately determine factory power levels

68.7 degrees in the dyno room

Maximum overboost pressure achieved via OBD2 datalogging was 18.6psi

Runs started at 1600rpm due to factory claimed torque peak which starts at 1950 – need a few hundred rpm while throttle is “rolled into” to prevent downshift, even in Sport Plus/Manual mode

Chris...please excuse my ignorance in advance.
Can you confirm which pulls were in 4th and which pulls were in 5th gear?
I'm guessing that #5 and #6 are 4th gear pulls with #6 in "Normal" mode and #8 and #9 are in 5th.

It's on the graph.

8&9-4th (Sport+)
5&6-5th (Sport+ / Normal)

Snorman

Duh...thanks. Not sure how I missed that.

Trust me man. Surprised I saw it-lol

Whollychit. Tagscribing this one.

Wouldn't it be easier to clamp on an ignition wire off the ECU?

Chris@Fabspeed

No, which is why the module we use is called "E-Z RPM". On certain cars we can use an inductive pickup on primary or secondary coil wires. We have a different pickup for each respective one. For example the new Mercedes E63 AMG I had to do this way, but the ECU and wire harness are right on top of the engine for easy access.

I pressure washed the engine underside and washed and detailed the car it's immaculate.
We have made a fabspeed Motorsport Maxflo race exhaust that is 2.75" 70mm with our cast stainless X pipe and no catalytic converters.
Next up HJS Germany Sports racing trimetalic catalytic converters with our Maxflo exhaust.

All the above will unleash power and sports car sound. The stock 991TT has 2 ceramic cats on each exhaust bank and going to larger 200 cell HJS HD cats will unleash power with no check engine lights and NO tunes required to eliminate cel lights.

We are also designing Quad tips and headers for this special car. If anyone you are closely our facility cruise by for a tour of fabspeed Motorsports USA.

More pictures to come..

The next time I'm in Malvern, Pa to visit my parents, I'll plan a trip to come take a tour.

Back in 2004,I bought exhaust from you guys for my non turbo 996 and used a private wrench for the install.

Who do recommend for the installation, dealer or private shop for the 991TT?

Can't wait for the sound bite!!
