I currently have the tubi street 200 cell exhaust with a tune from http://www.dkr-tuning.de/web/en. Was wondering if a 997tt with a tune and exhaust should be faster than a stock gt2. Had a buddy with me and raced a gt2, gt2 was about a car ahead till 170km then he startet to pull away after that. I understand the gt2 is about 100kg lighter, but the extra torque from the tune should at least compensate the weight difference. Am I expecting too much or is this about right?

 

Its gonna take a bit more than a tune look into upgraded vgt turbos and a good tune i use protomotive and had great luck

 

gt2 is really fasrter car

 

exhaust and ecu flash should take you to approx. 580HP. You should be able to keep up well with a GT2 which is lighter by 300lbs and at 530hp. The GT2 will pull away at the higher speeds.

 

I raced a GT2, a 599 and some rice box Evo. We all had the fortune of getting on the highway at the same time. The 599 got eaten and I had a few car lengths on the GT2, at about 120-130 the GT2 started to catch me, but I still had the lead. I don't remember what happened to the EVO.
I was surprised how slow the 599 was and so was the owner

 

A tuned 997TT with exhaust should run to 300 kph in about 31-34 seconds in a manual. A GT2 should reach 300 in about 33-36 seconds.

Drivers race, with GT2 likely benefiting from low weight, but greater drag due to its large wing.

 

hmmm, seems like my car isn't doing too well.

 

if you bump up to 650-700hp package, no problem with GT2 all day with a "drag" race; track times different story. i'm at 615hp with full tubi exhaust, BMC, BRVs, and GIAC tune, got dusted by ZR1, not even close! gonna get AWE 700 in the spring; look out ZR1!

 

Yes, ZR1's are quick, had one hand me my lunch at pocono this yr.

 

Hmm...this is a 630 tuned Evotech 997 against the ZR1. If you were at 615, I would have thought you would be closer.

 

try it and let us know...

 

I did, that's what happened. Started at 40 km and at 170 kms he was like a car ahead and after 170 he started going.

 

Do you have a vbox? Some data could help. What kind of fuel are you running?

 

I have headers, tubi, I/C and GIAC 91 oct flash the car dyno'd at 530 awhp. I raced a new ZR1 from about 30 mph. I got the jump on him and was ahead by a car length at the beginning. We raced well into fourth gear...he stayed with me and then caught me and if we kept going I think he would have pulled on me a little. I was happy he did not smoke me...and in my mind we were a pretty even match. Nice guy by the way, not all vette guys are so friendly.

On another note, I have run my Race 100 octane program a few times. All I can say is Holy Sh%t. Wish I was running the race program when I met up with the ZR1. I would have left him in the dust.

 

ZR1s dusted ferrari, lambo, and porsche in Motor Trend's all out test; not even close (YouTube). ZR1 ran the 1/4 mi in 11.0-11.2s; but i have seen (YouTube) 630hp tt run the 1/4 mi in 10.8s! i don't get it; modded tt should be able to take ZR1, NO PROBLEM?
