Last week 9Eleven pm'ed asking if he could use my Racelogic GPS unit to test his GT2. I said no problem and that I hoped he would post the data whether it exceeded his expectations or not. He replied " I seek the truth, nothing more. No ego here. Post whatever data the car produces" Well, it sure did produce!He even produced a 0-160 run...damn near fell off my seat on that one . He will update the car and the mods later I expect. This is a very strong, very impressive machine. I will get some of my GPS data in a bit and post for comparison purposes since it shows the evils of weight in these vehicles. These two vehicles make an interesting side by side due to their differing weights and power levels, yet overall equal performance data.Jean, I know the long G's are off on the 0-xxx runs, not sure why, but remember no accelerometers are used to calculate speed and distance.
For those of you who do not like run logs and graphs here is the Cliff Notes version:
0-60 3.73 sec
0-100 7.74sec
0-130 12.59sec
0-160 19.89sec
60-130 1shift 8.10sec
60-130 2shift 8.42 sec
30-50 1.27sec
50-70 1.30sec
100-200km 1shift 7.05
100-200km 2shift 7.40
0-200km 11.60

My hat is off to 9Eleven for making his data public. Congrats on an impressive GT2. Kevin

more....

9Eleven

I just got home after a long day and I was happy to see Kevin posted my numbers. What can you say about a guy that sends a 700.00 Racelogic to a total stranger? Kevin is a credit to every Rennlister, a trusting gentlemen who is just trying to learn what these cars are capable of doing. I feel the same way; I just want to know what they honestly can produce when modifications are done.

I am going to dyno her again as soon as I can get TPC to reserve some time. I am going to continue to monitor her progress; modification by modification. Right now she has a flashed ECU (Orton Performance) and Evo DV's, that's it. Oh yea, a new set of MPS2's. Those definitely made me feel better at 160. The 160 time could have been better, I didn't keep her floored through to 160, I think my self preservation instinct kicked in.

Thanks Kevin, I really enjoyed putting her through the paces. Although my wife thinks I'm crazy. Just for the record, it was in the low 50's air temp, a half a tank of gas, on a few runs there was a quarter tank and I weigh 210 lbs. So I think the car was tipping the scales at 3400 pounds give or take. Final note, 93 Octane pump gas.

That is one fast GT2 for just a flash, very, very impressive and those K-24's must
be blowing some good air!!!

congrats, and glad to hear Neil's new software is working as expected.

Congrats and thanks for sharing!

Come on Marty... I did beat him to 130 by .06sec I think he hit more bugs on the way to 130 than I did. Kevin

9Eleven - welcome to the exclusive club of those not afraid to reveal theri GPS data

How does the "height" scale work, it looks like the runs were done on a slope, is this right ? If yes what sort of slope, meaningful or not ?

Excellent numbers - PSI rate your package at what, 525hp ?

Edit
Just read what you said on 6speed regarding the slope (or lack of) - I know it is difficult making the call that the road is completely flat, even the airfield which we ran at recently had a bit of a slope on it

9Eleven

The road was as flat as I could find. The slope variable's were negligable. On a few runs there was a slope of 50 feet over a 1300 foot area. Not much of a slope. On some it went slightly uphill a dozen or so feet, then down a dozen or so feet, based on the GPS data. I did my best to get as accurate of a reading as possible.

It is hard to find a perfectly flat road for over a quarter mile especially in Maryland, maybe in Florida I would have had better luck. Hell, I think some of the quarter mile tracks even have a slope of 20 to 30 feet down hill. On the 0 - 160 run, I travelled 3000 feet, that's over a half mile. Try finding a road that is perfectly flat for over a half mile in my state.

I think Orton rates my flash at 530 hp and 545 tq at the fw. I think it's dead on or maybe slightly underrated. Remember prior to the flash, the car's best dyno was 444 hp with 428 tq at the wheel. Either way the car produces a lot of torque. It took several runs to keep the wheel spin down to get that 3.73 second 0 - 60 time.

9Eleven

That's at 1 bar! I'm trying to get the waste gate springs adjusted to get a sustained 1.1, but I really don't think that will make much of a difference. Probably more of a mental thing. More has to be better, right? Thanks for all of the kind words. I think it's good that we exchange information, it can only benefit everyone that is interested. Kevin is a hell of a guy.

Stummel

Thank you for the numbers!

It is certainly not easy to hit 3.73 sec. with the 2wd GT2.

A stock 483 PS GT2 does 0-200kph in 11.8 sec with the same 0-100kph of 3.8 sec.
I guess you are not shifting as fast as the testing professionals but have less weight than the test cars with full tank and passenger.

So it seems that you have almost 500 Porsche horses with only ECU tuning.

Congrats!


for comparison the stock 04 GT2 with 483 PS.
0 - 80 km/h 3,0 s
0 - 100 km/h 3,8 s
0 - 120 km/h 5,2 s
0 - 140 km/h 6,4 s
0 - 160 km/h 7,9 s
0 - 180 km/h 9,8 s
0 - 200 km/h 11,8 s

Stummel

for another comparison a 542 PS GT2 with ECU, enhanced turbos, exhaust and cats (a fast one though!)

0 - 80 km/h 2,9 s
0 - 100 km/h 3,7 s
0 - 120 km/h 5,0 s
0 - 140 km/h 6,1 s
0 - 160 km/h 7,3 s
0 - 180 km/h 9,3 s
0 - 200 km/h 10,7 s

funny thing is that it is 1.1 s faster from 0-200kph but only 0.5s faster from 0-180kph.
Jean, could that be a higher rev limiter resulting in 1 less shift?

Jean

The slope is fine, I don't think it will matter much. Getting it flatter is a real challenge, I am actually surprised that you were able to find such a long straight which is this flat in Maryland.

Stummel, any GT2 will go through the 124mph in 4th unless it has an 8k RPM limiter So they are being compared apples to apples. 9Eleven's shifts are excellent based on what I can see above.

Woodster

TB,

just to clarify, This is not a PSI product!!
I am surprised that has not been made clear.

Stummel, using the above referenced data... the stock GT2 does 100-200km in 8sec flat and the Modified GT2 takes 7 sec flat. 9Eleven's 2 shift 100-200km run is 7.40 sec which fares well against the modified GT2.I think the numbers are right where they would be expected. Kevin

Stummel

Kevin, you are right when looking at the 7.4s best 100-200kph run.
8.4s = 463 PS
8.0s = 483 PS
7.0s = 542 PS

so 7.4s should be 510-520 PS with same weight.
Although it has less weight with 50% fuel that is fast with stock exhaust.

I compared the 0-200kph times.
11.8s@483PS
10.7s@542PS

you get 11.6s@490-500PS.

KPG

All of you that preach GPS data has made a believer out of me. I will still go to the 1/4 now and then ,but theGPS data is just too much fun and very flexible. Kevin
