Finally got some drag times (Draggy) for my Taycan Turbo S

[iamai]

I am currently out of town is the only reason I'm not out time testing this with 90+% charge ?

There is a huge difference between 85% and 95% SOC on this car after 60mph. And this is on the completely stock car. I expect this to remain true even with the tune.

What I did not expect was any difference in launching power with the tune. I'll have to prep the car better to manage the torque I think.
I still did the same usual 2.7x second zero to sixty mph with the tune though, but I could feel and hear the tires squealing and screaming where they were usually quiet and almost deadhooking when it was stock.

To answer your question of if I feel a difference with a turbo S....yes very much so. To be honest even if this tune gave zero horsepower increase, the difference would be the just as intense with giving you a full 750hp with no throttle filtering at all times. Car feels completely different at all times

yes, on Turbo S the most noticeable improvement is when the car is in motion anywhere from 30-70 mph. You really have to be careful if there are cars around you as the pickup is really hard.
I will do my Draggy measurements and share at some point but probably only in August.

I have not been able to get clear roads to make runs (my usual spot is only good on weekends since it's completely out of my way on weekdays, and I have been traveling a lot on the weekends).

Preliminary unprepped runs show no changes post-tune. However, I have not had a run with time to get a good satellite lock either so there is that (low satellites have always resulted in a slightly slower time for me on the draggy)

This is from a few days ago.......

I am just noticing how consistent the times are LOL. I have a third run which is almost identical as well. 10.38 at 131 plus mile an hour
These are all not prepped runs. Tire pressure is on my normal driving of 44/45 PSI

what do you mean by that? You actually have a drag strip you go to?

How is my trap speed the same as yours?

Probably because the tune puts out the same BHP (800 BHP)

No just a flat long spot with no cars around

My tuned GTS is only putting down 10.7 @ 129 in the quarter mile. Clearly there is a hardware difference between the GTS and the Turbo S that cannot be overcome by unthrottling the software.

Mr. Smith’s results don’t really make sense to me.The only conclusion I can come to is that the Audi has something else going on with its hardware/software.

Something else I forgot to mention. After the tune I noticed much higher battery usages that was slowly getting better but definitely noticeable. I was using a ton more kw going to and from work as well as to the airport. When I tried to make a draggy run the first time post tune after charging to 100%, by the time I made it to a clear spot, I was down to 92% (usually I will be down to 96% pre tune to the same spot). I lost 2% of battery by the time I made it out of my driveway to the main road.

So I reconditioned my battery by draining down to around 6-8% and left it for 12-14 hours. Then recharged back to 100%.
I actually use less battery now than before the tune. The battery pack seems to run cooler, and I get to the same spot with 97-98% soc (improvement of -2-3%).

This isn't the first time I've reconditioned/balanced the battery. I did this about 2 or so months ago when the car was completely stock.
It was after the reconditioning that I started to get the more consistent faster runs I posted in the first post on here.
Let's see what happens in a week/month or so now.

Another thing is wheel spin. The tires now howl loudly through 40-50mph since the tune.
Does not feel like it's really spinning (probably cos the ecu is stopping it), but it's the loudest I've heard these tires ever since buying the car.

Prior to the tune, the was barely a squeak when launching. The tires were a ton more quiet for sure. And when I lowered my tire pressure, it would just about dead hook.

I spoke to Mario about this and he confirmed that power is being pulled out of the motors probably through 60mph for traction. So I'll lose time there. I have to improve traction if I want to go faster for sure with the tune.

okay…it took some digging but I confirmed online what I thought I had read previously, the Turbo S does have different hardware. From Car Magazine article:

Also shown is the inverter, which, for the front motor, comes in two flavors: 300 amp peak output (190 amp continuous) and 600 amp (380 amp continuous), with the latter coming in the Turbo S and enabling a maximum output of 255 horsepower and 325 lb-ft of torque during short launch events (and 295 lb-ft for longer durations). The standard Turbo model’s front motor, with its 300 amp inverter, pumps out 238 horsepower and a maximum of 221 lb-ft.

This make sense and explains why I am still not quite at Turbo S overboost-level performance. FWIW, I still would highly recommend the Redshift tune!

RS E-Tron GT, Taycan GTS, Turbo, Turbo S are all the same hardware, with a 600amp inverter on the rear motor.
Turbo S just has the 600amp inverter on the front motor to give it a better launch.

The 600amp inverter for the rear motor is the exact same part number for the Turbo S front motor.
A friend already tried installing that 600 amp inverter on the front motor of his RS E-Tron GT, but the software was not compatible.

Mario has been working to make that 600amp inverter compatible for the front motor.
When that happeneds, your GTS will be a Turbo S

0-60 is such a small percentage of driving fast or racing. It's all about the 60-130mph which where all the action happens. That's the benefit of the Redshift tune

Not to be argumentative (and apologies as it was from Jalopnik, not CAR), but directly from the article:

The two inverters, which yield 168 pound and 157 pound total weights for the front axle module, save cost by sharing quite a few components, Porsche says. It’s not clear if the 600 amp rear inverter is the same as the 600 amp optional front inverter, but I bet it is. (Update: Porsche says it’s different).

Also, what is your basis for your claim that the more powerful front inverter only helps with 0-60 as opposed to at all speeds? I am struggling to understand how that would be the case…

The easiest way to confirm the 0-60 is from the from inverter is the Turbo and the Turbo S are identical HP when not in launch control and from data on the Internet, the same 100-200km times, along with the RS E-Tron GT that is .02sec slower, which is a software detune

i I think the fact that the Turbo and Turbo S have the same “base HP” is down to the software…all else being equal, being derestricted, an inverter with a higher Amp rating is going to deploy more power, period.

I plan to do some additional testing of 60-130 from a roll vs from a dig to see if my time improves from 7.99 sec. If the premise that the power output is being throttled due to temperature management is accurate, then I would expect to see better 60-130 metrics from a rolling start at say 50mph as the motors/batteries are being asked to deliver max power for a shorter duration than a 0-130 run.

I would love to see 60-130 times similar to what you have quoted with your car, but am skeptical given my displayed battery temps started in the mid-80’s during my quarter mile attempts and only rose by a few degrees during my brief testing. I do appreciate there may be a difference between instantaneous temperature increase at specific components vs the ”global” temperature of the batteries/system.
