Yes with sport Crono

 

OK, I am learning the Driftbox and graphing functions thanks to KPG. The original times that I posted for our 545 HP /590 TQ upgrade were incorrect. I had a 1 foot roll out feature enabled which is only for the 1/4 mile timing. I ran the car again tonight on my way home from work and here are the times with the 1 foot roll out disabled:

EVO 997TT 545 HP / 590 TQ
Best, Average
0-60: 3.3, 3.5
0-100: 7.5, 7.6
1/4 mile: 11.30 @ 126, 11.40 @125

I will post the graphs as soon as I can. We are in the middle of moving into our new facility and have all of my data transfer cables packed. Thank you KPG for the info and sample graph.

 

Dayyum, this is gonna be faster than the 996 GT2 was stock, which is scary but not in the 997TT it wont be it will be shmooooth.
Good work Todd.

I'm glad that you discovered the roll out error. The data log would have clued you in when it indicated that the car was moving at 4 miles an hour with a 0 feet distance travelled. Looking forward to the results.<!-- / message --><!-- sig -->

 

Maybe someone can explain this to me....with all the talk about errors in readings etc.. It does seem that something is really wrong with these numbers....

Here are the results from 3 different magazines on stock 997Turbos:

Auto Motor Und Sport (stock997TT) :
0-62mph: 3.7 s.
0-100mph:8.0s.
=> 62-100mph: 4.3s.

Sport Car (stock997TT):
0-62mph: 3.8 s.
0-100mph:8.4s.
=> 62-100mph: 4.6s.

Car Magazine (stock997TT):
0-62mph: 3.9 s.
0-100mph:8.2s.
=> 62-100mph: 4.3s.

Here is the 996TT X50:
0-62mph: 4.1 s.
0-100mph:8.5s.
=> 62-100mph: 4.4s.

And a stock 996TT (420HP)
0-62mph: 4.2 s.
0-100mph:9.4s.
=> 62-100mph: 5.2s.

EVOMS Stock (stock997TT) :
0-62mph: 3.8 s.
0-100mph:9.7s.
=> 60-100mph: 5.9s. This is slower than a stock 996TT by a bunch including a 0.1s from 60-62mph.

Hence why the modded car seems so much faster when compared to stock..What gives?

 

Todd,

Do you plan to do any work with a tiptronic 997TT?? That would be very interesting. Might be close to a 3.0 sec 0 to 60??

 

Jean,

I guess that as with anything, there are no absolute ways to compare with 100% accuracy. The dyno tests cannot be compared due to different dynos / operators, the driving tests cannot be compared due to different equipment, methods of use and or drivers / methods. I think now that I have more seat time in the car, my stock numbers could be improved upon slightly. The other consideration is my testing in my conditions may not be an apple to apples comparison to the magazines that you mentioned. Bottom line the way I see it is all of this data is good but will never be a 100% absolute science.

 

<!-- / message --><!-- sig --> Yes it did after I downloaded the graphs and received some guidance from KPG. This is when I decided to check and change the settings and retest the car with the changed 1 foot roll out feature. When I had been using the driftbox prior to this discovery, I was resetting the driftbox in between every run and just writing down the results that were displayed on the unit itself. It does not show any data besides the 0-60, 0-100, etc times for that specific run.

 

Without a doubt we will be working on the tiptronic cars. It will be interesting to see what times it can produce. The tiptronic car will be an easier car to more accurately test 0-60 / 0-100 times due to fewer inconsistencies with driver ability / error. I am looking forward to seeing the results.

 

That is amazing. Wow. Great work.

 

Todd, I agree.

A difference of a couple of tenths can certainly be due to many external factors, but here we have three different magazines being quite close to each other, and your run was about 28% off the slowest run, that's over 130hp difference alone when comparing between stock and "tuned" side by side..

As you said, your stock runs seem to have been quite slow.

I grabbed a bone stock 993TT last night and did many GPS runs, my times were almost spot-on with a magazine test that was published back at the time.. 10 years later. Differences can only be small, certainly not of that magnitude. I cannot post the comparison now for some reason, I will upload it later.

 

Todd, any data can be pulled off the SD card and scanned for a specific test ie: 47mph -84 mph.. anything can be done. The data displayed on the units screen is not the final number due to the lack of a second decimal place and the way the unit rounds numbers. For example: 9Eleven used my unit and told me he had done 0-60 in 3.8 sec and 0-100 in 7.7 sec. Once the data is run thru Vbox tools, like the run log of my 0-60 times I sent you, the actual figure is produced. 9Eleven's 0-60 was actually 3.73 sec so he was faster than the units display.His 0-100 time increased to 7.74 . Also, there are 2 user programmable accel ranges that can be viewed in the accel 2 screen. I programmed 0-130 and 60-130 for 9Eleven so he would have a good idea of the vehicles real time performance.Just some thoughts. Kevin

 

Good numbers Todd! I want a ride when I come down to the shop next time....

 

The 997 Tip is a real blast after a ECU flash.I did one last week and it sure does motor.

What kind of numbers are you seeing after flashing??
