It's Official, SLR Vbox times

Took the SLR out for some Vbox runs this morning. It was a cool 52 degrees and sunny. I started with some 60-130mph runs. With traction control off and sport mode on, I downshifted into 2nd gear at 50 mph and hit it. I let the automatic do all the shifting. I did 4-5 runs and it was fairly consistent. Best of the bunch was 7.24 seconds on a 2.77% decline. This beats the 7.85 second time I got with my former LP640, and the 7.48 second time I got with my Renntech SL65. Also for more comparisons, I have run 5.94 in my TTG on pump gas, 5.22 on race gas, and with my newly acquired 997TT tip my best is 6.73.

 

Next I thought I would try a couple 0-100mph runs. With the weather being as cold as it was, I wasnt too optomistic about getting good traction. Turns out I was right and even though I started in comfort mode (which starts in 2nd gear), the car didnt have much traction until like 50 mph. The esp light kept coming on and cutting power, but I still managed a halfway decent time on one of the runs. I will try again when the weather is warmer, and I can get better traction.

 

0-10 0.4

0-20 1.2

0-30 1.8

0-40 2.4

0-50 3.0

0-60 3.7

0-70 4.4

0-80 5.2

0-90 6.2

0-100 7.3

 

The SLR's 0-100mph (7.29) is faster than my time of 7.41 in the LP640 and 7.38 in the Renntech SL65. With better traction the SLR will easily improve its 0-100 mph times, although it will be no where near my best time of 6.37 in my TTG on pump gas, or my best time of 5.89 seconds in my 997TT tip.

 

Here are a couple of pictures of the Vbox display.

Impressive.

Just wanted to remind you of these:

 

My Post:

2. In a 60-150mph race, I maintain that a stock SLR will be approx 5 cars ahead of the stock LP.

 

Your post:

2. In a 60-150 race, a stock SLR will likely be ahead of an LP640, and maybe in AZ it would be 5 cars. Although I think that given normal conditions (normal elevation and temps), the LP would only be about 2 cars behind max. The acceleration is not night and day as you claim, and the LP is by far the better looking and more comfortable car.

 

 

 

Now Id like to revise my statement and add that in a 60-150mph race an SLR would be MORE than 5 cars ahead of the Lp

 

So to reiterate... I said that an SLR would catch and pass an Lp640 before 100mph....making up the massive lead the Lp gained on its initial launch. From a roll the SLR will walk an Lp. They say every 1/10 of a second in a quarter mile is equal to 2 cars, not sure how that translates from a roll. You gained 6/10's just in a 60-130 run, and we talked about 60-150mph. If you went from a roll of say 10-15mph with the Lp, the Lp wouldnt know what happened.

 

#2. I said that a STOCK SLR is faster than a modded SL65

 

Not trying to be arguementative here at all. Im soo happy you got an SLR, and now I think you can somewhat see my frustrations with it. Not only are you dealing with a car that doesnt give you full power till 80mph, you still deal with massive traction issues to around 50mph where the ESP is pulling even MORE power. If you could solve the traction issue with just a set of sticky tires, the SLR would obliterate any of its listed times easily.

 

As for the TTG, I still stand by my word, a Modded SLR, with the right tires, against an early G TT on pump gas will be a very very close race in 0-130-140mph dash.

 

On a side note against the modded Porsches, I raced the SLR when stock against 3 modded Porsches.. 2 of them, Rakjoes 996TT and a 997TT made around 575awhp, and the SLR was slightly quicker than the 996TT, and seemed to be about even with the 997TT in a 160mph run when the SLR was stock. SeccJoes 660rwhp GT2 in a 40-140 race was faster than the SLR by a couple cars after the SLR held strong to 100mph.

 

Damn, now I miss my SLR...

 

 

 

 

 

those are incredible times!

 

comparing those times to those from your LP640 (done on the same road?) the LP640 is basically gaining ground for the first 7 seconds after which the SLR is making up ground.

 

any distance results? the 1/4 mile run in your LP640 was 11.3 @ 126-127 mph.

Another way of looking at it is that from a dead stop at 60mph the SLR is 7/10's behind... From 60 to 100mph it gains back almost a full second.

 

I also wonder what the shift times between the SLR and the Lp look like.

 

As for the 1/4, I think Acichelli might be able to dip into the high 10's, 11.00 @130-131 on his Vbox.

I see you reading this allan

Of course. This is my favorite thread in the last year. Better than any TT G thread.

 

On a side note, brand new 997 GT2, with one shift recorded 60-130 in 8.1 seconds.

yes, but if you look at an isolated 60-100 time the SLR gains back almost a full second, but the LP640 shifts right after 60, and going by Aaron's times, the LP640 hit the rev limiter. at 70 mph thought, the LP640 took 4.3 seconds to get there, and the SLR took 4.4 so looking at a 60-100 mph time rather than a 70-100 mph (during which he didnt hit the rev limiter) plays more into the hands of the SLR.

 

my argument is that right off the line the LP640 gains a lot of ground and for the first 7ish seconds (with good shifts) would slowly be gaining more of a lead. but at a little over 7 seconds, they will be going equal speed, after which the SLR will be gaining. its hard to tell how these numbers translate into distance though.

 

 

BTW, so a GT2's 60-130 is slower than a Plastic mess-06?

LOL, youve got more excuses than a convict going to jail. The fact is that in ANY measured distance of speed other than 0-60mph, the SLR will destroy the lp640. Not to mention that in the 60-130 run, the SLR doesnt fire on all cylinders until it hits 80mph and is shifting to 3rd. There is another measure of speed that several magazines like to do.. the street start, from 5mph on. Watching that race would make you cry.

Haha Allan, dont bring up what I said in the past. I was totally biased back then towards the LP, and now I am totally biased towards the SLR. So obviously now that I have picked having the SLR over the LP, it would be at least 5 cars ahead in a 60-150mph race.

 

The distance results for that 0-100+ mph run is as follows

 

Distance() Time(s) @Speed(mph)

0-60' 02.1 35.3

0-330' 05.2 80.0

0-660' 07.7 103.6

 

I will have to dig up more info on the LP and SL65 info to see how they compared.

I should move to this to the general section for all the abuse i took from all the know it alls who said that an Lp is faster.

And not to mention the MbWORLD idiots who said that an SLR is about as fast as a stock SL65, one idiot wrote of racing a 722 in his stock Sl65 and pulling on it!

I found this for the LP quarter mile run with power launch on the same road I did the 0-100+ mph in the SLR

Can you do a 1/4 mile run there in the SLR

 

I did run one the other day in the cold weather, but I wasnt hooking up well at all on that run. The distance results were as follows.

 

Distance() Time(s) @Speed(mph)

0-60' 02.1 35.3

0-330' 05.3 78.7

0-660' 07.8 102.9

0-1320' 11.6 124.3

 

I know the car will easily trap higher.

Yes, you certainly need a better run than that. Your trap speed should be a few mph higher than my actuall 1/4 mile speed. Im figuring 130-131mph.

Send me that bloody Vbox will ya, i wanna see if i can beat these times.

Nice runs Aaron!! How many shifts for the SLR in the 60-130 pass, how fast does the SLR change gears, and how does that compare to the LP640(in terms of the amount of shifts and speed of shifts for each car)?

Thanks Bernard. I believe its 2 shifts, one around 80ish and one around 123ish. I just went out with the Vbox and ran a quarter mile in the SLR, I will post the results shortly.

 

Aaron

 

Btw Bernard, its too hard to tell how fast an auto changes gears, and where the shift points exactly are using the graphing software. The autos ease in and out of the gear shifts, making it hard to tell where the long Gs drop and pick back up.

 

Aaron

 

Temp was up to 67 degrees (still too cool for great traction), so I took the SLR out to try another 1/4 mile run. I figured out why my other run's trap speed was so low. It was because I let up before the end of the quarter. The road I am doing these runs on, has barely enough room to run a quarter mile and still have enough time to slow down. I did 2 quarter mile runs. The first one I got a good start, but I didnt run all the way through the quarter and still ran an 11.5 @109.9 mph. The 2nd one I didnt as good of a start, but I held the gas all the way through and ran 11.5 @ 129.4 mph.

 

Heres the Vbox pics.

 

On the first quarter mile run attempt, I captured the 0-120mph results on the Vbox.

 

0-10 0.4

0-20 1.1

0-30 1.7

so 11.3 @ 126-127 for the LP640 and 11.5 @ 129-130 for the SLR. both of which you said could be improved upon, right?

This is your second run no? The vbox pic shows the quarter mile @109.9mph in 11.5 seconds on your first run. The first results might be wrong, because you would need a much better 60ft time to have the same ET in both runs. The huge difference in trap speeds is puzzling.

 

Great trap speed on the second pass. Congrats!!
