Has there been a faster tune and exhaust only 991.2 Turbo S with a timeslip from a dragstrip?

 

Very impressive and with minimal mods.

I am wondering if you can run E30-40 with the same performance of the 100octane tune. That would be very nice as the cost of E vs 100 makes it a daily 139 trap car.

again congrats!

 

Thanks for sharing the vid!

Have to give credit to our partners at GIAC for really taking the time to work with us on this one! Several days on the dyno, pouring through LOADS of data, and really understanding the process....that's why we continue to partner with and support GIAC.

For a car running nothing but a Tubi Race exhaust and the GIAC software with 93 and 100 octane maps, we could be happier! Talk about bang for your buck!!

This software is now readily available and OBDII-flashable for anyone with a 991.2 Turbo S.

 

Curious where you think a .1 Turbo S would end up with the same mods?

 

The .1 needs a full stage three seup to match a stock 991.2 TTS in some measures. To get where MrJoshua is (and a little further actually), you need to move to larger turbos, like the 68mm VTG rebuilt ones. Near 140mph trap on the stock turbos with just tune + exhaust is fast AF.

 

I think the best we've seen one of our .1 Turbos with similar mods go is around 10.2 at about 134/135. The .2 cars seem to do significantly better thanks to the slightly larger turbochargers on the S models as well as some slightly better fueling.

 

Old 991.1 Turbo S running 10.2's with same mods on Stock tires


I think the best pass was a high 10.1X at 133 mph on stock tires with a 1.45 60 foot.

More than ET, the 991.2 Turbo S is 6 - 7 mph faster in the traps.

 

Bought my 2017 991.2 TTS and it already had a Tubi Catless Exhaust and a GIAC tune on it, installed by Porsche of Houston.
Just called GIAC today and found out my tune is only their Stage 1 plus... 50-60hp gain.
Called my local GIAC dealer and I can upgrade to their Stage 2 plus for $150.
So, I'll give that a shot and see if the 60-130 numbers come in closer to where they should be (Minus the passenger and extra cargo from my previous 7.28 and 7.31 60-130 pulls)


Well, just so I'd have a good idea of the gains from their Stage 1 plus to the Stage 2 Plus (when I get it upgraded), I went out tonight and made sure I got some pulls with just my heavy A$$ in there ( GIAC Stage 1 plus)

So here were the conditions:
- Me with a lot of gear on (two Glocks / spare mags and a few other items) = Approx. 275-280 lbs. min. and a jacket in case I got a flat or some (cold out)
- DA was -486 (36-37* , 78% humidity, 900-990 Ft. Elevations) and Quite Windy!!
-1/2 tank of 93 octane.

The only place near me to do this safely is a section of Hwy over a bridge (Bumpy and slightly sloppy depending on direction). You'll see the results.
I'll upload and post a couple of vids later. Here are the Dragy Stats.

60-130 Pulls
Quickest was a 6.69 ( -1.10 slope )
Slowest was a 7.11 ( + 1.19 slope )

 

Thanks, I'm leaning towards 68's.

 

That's still pretty stout for stock turbos.
Thanks for the reply.

 

@MrJoshua are you the owner of the car? would be be great to add it to the 6speedonline 1/4 Mile list
