It's Official, SLR Vbox times

So I did some more 60-130mph graph comparisons with several of my cars.

 

First I compared the TTG on PUMP gas, the SLR, the Renntech Sl65 and the LP640.

 

The 60-130mph times are as follows:

 

TTG: 5.93 seconds over 849.50 ft

SLR: 7.24 seconds over 1056.79 ft

SL65: 7.48 seconds over 1082.56 ft

LP640: 7.85 seconds over 1144.85 ft

 

After looking at the graph comparisons I determined the following:

 

When the TTG on pump hit 130mph, it had traveled 849.50 feet, and at this point the:

 

SLR was going 121.86mph and was behind the TTG by 35.44 ft

SL65 was going 119.08mph and was behind the SLR by 15.85 ft

LP640 was going 119.49mph and was behind the SL65 by 2.23 ft

 

When the SLR hit 130mph, it had traveled 1056.79 ft, and at this point the:

 

SL65 was going 128.3mph and was behind the SLR by 19.84 ft

LP640 was going 126.12mph and was behind the SL65 by 4.26 ft

 

When the SL65 hit 130mph, it had traveled 1082.56 ft, and at this point the:

 

LP640 was going 127.7mph and was behind the SL65 by 5.04 ft

 

 

I then did the same graph comparison again with a different combination of cars. The cars included and their 60-130mph times are as follows:

 

TTG on race: 5.21 seconds over 749.54 ft

TTG on pump: 5.93 seconds over 849.50 ft

997TT Tip: 6.73 seconds over 985.60 ft

SLR: 7.24 seconds 1056.79 ft

 

After looking at the graph comparisons I determined the following:

 

When the TTG on race hit 130mph, it had traveled 749.54 feet, and at this point the:

 

TTG on pump was going 123.51mph and was behind the TTG on race by 22.66 ft

997TT tip was going 118.38mph and was behind the TTG on pump by 19.89 ft

SLR was going 116.79mph and was behind the 997TT tip by 8.43 ft

 

When the TTG on pump hit 130mph, it had traveled 849.50 ft, and at this point the:

 

997TT tip was going 123.42mph and was behind the TTG on pump by 25.66 ft

SLR was going 121.86mph and was behind the 997TT tip by 9.84 ft

 

When the 997TT tip hit 130mph, it had traveled 985.60 ft, and at this point the:

 

SLR was going 127.11mph and was behind the 997TT tip by 12.66 ft

 

I did this to determine how far ahead or behind each car would be distance wise. Time to get to a certain MPH can be deceiving and this simulates more of a roll on race. I know its hard to visualize, but hopefully this helps.

I did another graph comparison of 3 cars, this time 0-100mph to see how far behind or in front the cars would be. The results were very interesting, especially when comparing the SLR and LP640.

 

Cars involved and their 0-100mph times and distances.

 

997TT tip: 5.89 seconds over 536.52 feet

LP640: 7.41 seconds over 662.95 feet (egear power launch)

SLR: 7.29 seconds over 601.16 feet

 

When the 997TT hit 100mph it had traveled 536.52 feet, and at this point the:

 

LP640 was going 88.19 mph and was 89.21 ft behind the 997TT tip

SLR was going 84.39mph and was 64.25 ft behind the LP640

 

When the LP640 hit 100mph it had traveled 662.90 feet, and at this point the:

 

SLR was going 99.61 mph and was 68.17 ft behind the LP640

 

 

The reason the LP640 hit 100mph faster than the SLR but the SLR's Vbox time was faster (7.29 vs 7.41) than the LP640 is because of the Rollout setting.

 

All magazines use the 12 inch rollout when doing their acceleration tests, 0-60, 0-100, quarter mile etc. This is done to simulate the drag strip start.

 

Well on the Lp640s run, the rollout (how long it took the car to move 12 inches) was only .35 seconds, and the SLR's was .52 seconds. When I compared the graphs I had to ignore rollout and start from a true zero, since I was doing this to see who would be ahead in a race. FYI, the 997TT tip's rollout was .31 seconds.

 

I have yet to get my best 0-100mph SLR run to use to compare, but the data shows so far that by the time the LP640 hits 100mph the LP640 is about 4.5 car lengths ahead of the SLR. The SLR is obviously catching up and will pass the LP at some unknown point, as evidenced by the 60-130mph comparisons.

 

What I am really impressed with is how badly by 100mph the 997TT tip had annihilated the LP640 (which had an egear power launch start and did 0-60 in 3 flat on that run), and was 6 car lengths ahead of it at that point.

Nice the Autobox Porsches ability to put power down on boost is awesome.

Looking at it again, its actually an interesting contrast between the porsche and GTT, and the SLR and LP. On paper the Porsche looks to be the far faster car, when in reality its not. Its just much more efficient at putting the powerdown from a stop.

Its only putting down a bit over 600 to the wheels, so its obviously not going to be faster from a roll than a TTG. Its fast spooling turbos and Its ability to put the power down to the ground from a stop is precisely why its a great car to own. I nicknamed it the "stop light crusher." It is definitely one of my favorite cars.

Ya, I love it.

 

wow! talk about comprehensive! thanks a lot for taking the time to write all that.

 

the 997TT Tip is REALLY impressive. but is it a surprised that its faster than the Lp640 by so much. sure the LP640 has it launch control feature, but the Turbo is what, 500 lbs lighter? not to mention making 100+ more whp AND not getting any traction issues ( engine over the rear wheels and it still awd, right)? is there really anything short of a Veyron that can take that 997 from a traffic light on the street?

 

edit: about the rollout, does it mean that the TRUE 0-100 time- from a dead stop- for the LP640 was 7.76 and for the SLR 7.81?

Oh god.. you will never stop grasping.

I dont think the 911 turbo is quite 500 pounds lighter, my guess is more like 300 pounds. The fact that the LP went 0-60 in 3 flat and the 997TT was 2 car lengths ahead by 60 mph and 6 car lengths ahead by 100mph is very surprising and extremely impressive. Keep in mind that this 997TT tip is running stock tires, PS2s. "Not getting any traction issues" is easier said than done. This car has the perfect ingredients to make it possible.

 

I am not sure if you are familar with the other 997TT 6 speed I am having upgraded with the "Sledgehammer" package. The first "Sledgehammer" upgraded car ran a 9.7 @146mph quarter mile at the drag strip. (it will trap in the 150s, but 4th gear redlines at 146, so on that run the guy stayed at 146mph for the last 100+ ft of the run) The guy also had a driftbox in the car and I have the graph from that run. The 0-60 was 2.54 seconds, the 0-100 was 4.89 seconds, and the 60-130mph was 4.89 seconds on the same run. Now when I compare that graph to my 997TT tip graph, the 997TT tip is ahead of the Sledgehammer while its going 0-110mph, the Sledgehammer finally takes the lead at 110.64mph. It finally pulled 1 car length at about 122 mph.

 

Yes you are about right on the Rollout stuff. But dont worry, I am going to beat the LPs 0-100mph and quarter mile time with the SLR soon enough

 

Aaron

how does the launch consistancy in the 997, SLR and LP compare? you said the LP was fairly consistant with the 0-60 time. how do the SLR and 997TT compare? probably can take more abuse than the LP, right?

Oh god.. you will never stop grasping.

 

I really enjoy reading your thread Aaron. Thank you for taking the time to post all this real world info. I love your cars

The launch on the 997TT is the most consistent. Then the LP640, and then the SLR. Theres no abuse to the SLR when launching other than to the tires. The power launch on the LP640 is pretty hard on the car. There is probably some stress on the transmission of the 997TT when doing the brake boost, but it should be minimal.

Thanks a lot for the info!

 

one last question though, how man power launched do you feel an LP640 could take without issue?

Really dont know. I know that you have to steer through 4 wheel spin to keep the car straight, it's not an idiot proof launch.

 

Aaron

 

Dug up the best 0-100mph run with the LP640 without a power launch and compared the graph for that to the SLR's 0-100mph.

 

Lp640: 7.86 seconds + .39 rollout

SLR: 7.29 seconds + .52 rollout

 

When the SLR hit 100mph it had traveled 601.15 feet and the:

 

LP640 was going 95.84mph and was 20.70 feet behind the SLR

 

 

Also dug up the 11.9 @127.6 quarter I did with the LP640 without power launch on a 2.5% decline and compared it to the 11.5 @ 129.4mph I did in the SLR on less than a 1% decline.

 

Lp640: 11.96 seconds + .37 rollout

SLR: 11.52 seconds + .60 rollout

 

When the SLR hit 1320ft it was traveling 129.39mph and the:

 

LP640 was going 126.24mph and was 38.03 feet behind the SLR

 

So in a nutshell, an egear LP640 without doing a power launch is very likely to lose against an SLR from a stop.

 

Aaron

can you compare an LP640 powerlaunch vs LP640 without power launch? it would be interesting to see how much of an effect the launch has.

Ok here you go,

 

0 to 100mph comparison:

 

Lp640 with power launch: 7.41 seconds + .35 rollout

Lp640 no power launch: 7.86 seconds + .39 rollout

 

When the Lp with power launch hit 100mph it had traveled 662.91 feet and the:

 

LP without power launch was going 95.42mph and was 88.69 feet behind the Lp with power launch

 

Quite a big difference.

 

Aaron

 

So.......many.......statistics......lol

its like the matrix, you're scrolling the page and all you see is numbers and stuff

 

Thanks for the info Aaron.

Aaron, I just looked at the graph with the 0-100 of the SLR 997 and LP640, and is it just me or the SLR's curve super SMOOTH!? the 997 TT is an auto too, right? it still sees a little wiggle in the curve, and the LP640's two shifts are very aparent.

Aaron, is it possible to view acceleration-time graphs rather than just speed-time graphs?

What do you mean by acceleration? Longitudinal Gs?

ya, I guess m/s^2 on the left rather than m/s.
