Only did a couple runs in the 997.2. New fuel system allowed for a lot more top end than the stock system could handle however placement of the new fuel system hardware caused a code and resulting limp on every run (getting fixed now). Despite that had two runs where I didn't limp until the very end of the half mile. As posted in my previous thread vBox accel stats were better than ever before in such high DA (2,500-2,700 feet):


60-130 6.1-6.2 seconds
1/4 mile 139.9
1/2 mile 167.66


I didn't get many races in the 991 either. I asked but not a lot of people in the other cars wanted to race as the 911 Turbo's flat out dominated everything at the event.


Cheers.

Wow! That 991 TTS is moving. Can't wait to join the club!

 

Great vid as always!! 991 TTS is just on another level, damn!

 

Thx gents!


I have found that the 991 with just a tune is pretty much the fastest tune only car 0-130 on the planet with the exception of the 918 and maybe the Veyron (although the Veyron would be close). I can't think of any other car with just a tune including the P1 that could keep up. It is very efficient with it's tiny 56mm turbos. On pump with a couple gallons of e85 it did a 6.6 60-130 verified on a relatively flat slope of -0.5 on my very first try. I'm sure I can drop a couple tenths off that. I doubt the 997.2 TTS tune only can do that. Even tho it has the same motor and trans, the hardware on the 991 is more improved.


The 991 will stay tune-only while I figure out how far to take the 997.2 now that I have a much more robust fuel system.

 

Very nice! Bothh your rides are beasts....Good job....991 is impressive....

Take care,
DC

 

great video! Both cars look great. Will be interesting to see when you get the 997 sorted!

 

Great vids and stats LB. Whats frightening on your 997.2 t is I still think there's significant improvement once you've debugged the new fuel system - to gain same performance on gen 1 997 t platform you need built engine and 800hp. Agree re 991.1 turbo = rapid out of the box.

 

got damn Adam your 991 is fast.. that launch is crazy hahah

 

Your cars are absolute weapons.

 

Very Impressive !!!

Now im debating if to modify my 997.2 or to upgrade for a 991...

Will be nice to see both of them head to head after you sort the 997.

Thank you for sharing!

 

When it was happy it was fast Adam! You could totally tell when you had a good run vs a limp mode run.

991TT all the way though guys! All the 991TT's were KILLING it! Especially the white ones!

 

Awesome video - thanks for sharing.

As stated previously - you have a pretty mean garage there! I love watching you smoke the competition - keep it up!!

 

That F12 race, LOL.

 

Thx bro. Any more mods for you before the next NFZ Midwest? e85 maybe

Thx. Hopefully I'll get back to NFZ Arizona again. Did you go last weekend?

The stock turbos probably cannot flow much more. I think 140 1/4 mile trap is the limit on stock weight. I do think the 1/2 mile MPH can improve a little since I was limping the last few hundred yards of my best runs. So maybe close to 170mph. But if I want to go beyond that I will need the Champion 68's. Not for now...I want to see how I can do for a while on the stock turbos at other events and at the track. GIAC created more of a linear profile on the boost profile so it feels better at the track. Not sure I want bigger 68's messing up this really awesome powerband!

Bro, Austin@GIAC has a pic where it looks like my front tires came off the ground on the launch. On stock tires and crappy surface. The launch on the 991 is no joke!

By the way what did you get into? A GT3?

AWD+Turbo+PDK is certainly formidable recipe! Porsche gets all the credit.

Keep the 997.2 as it will be less expensive in the long run.

The 991 has much more potential because of a larger stock fuel system so you can take advantage of larger turbos. But if you are keeping turbos stock, the 997.2's are larger (56mm for the 991 vs 61mm for the 997.2).

The race against the Agate Grey 991 is forum member Mark Blackwell. On that same setup (GIAC Stg 2 with MT drag radials) he did a 10.1 at 134.Xmph which is the USA record for stock turbos with no nitrous. As you can see I flew away from him in my 997.2 which also has stock turbos.

There are definitely pros and cons to both the 991 and 997.2. They are so different I don't know which one I like better. Sometimes I like the 991 but other times I like the 997.2. Porsche has given us an incredible platform either way!

Thx bro! 2 more airstrip events in April.

Funny thing I actually hit the rev limiter on my launch which stalled the car for a split second. If you watch the vid again you can see my momentum slowing just after the start. But it didn't matter...cause 660 Porsche horsepower is obviously much faster than 731 Ferrari horsepower

 

Hi Adam,

Congrats on the 991 and kuddos for all the races on the 997.2.
