1st of That video i posted was run by me. So when u doubt something you are doubting my credibilty as a 6speeder here. Here is a pic of the car i shot right before the race. The Badge in the back clearly says HKS 600 while the owner him self told me it's the 620 package on.



2nd The video you posted states 612 Dyno run. Which is equivilant to somewhat 700~. While my comparison lies on crank Hp.

3rd if u look closely at the video you posted even with nearly 200hp advantage that GT-R barely pulled from a roll. And from a dig the turbo S had him ..



I'm absolutely with you on that. But, the video's posted were not random. We don't advertise for certain products and we are not shareholders in Porsche . Therefore, what you see is what you see

 

First of all, all mighty credible one, it doesn't matter if that car had a HKS 600 sticker on it or a HKS 10,000 sticker on it. Bottom line is that a 620 HP GTR is not going to get ruined by a 500 HP PDK like your video shows. That is a fact that all unbiased Porsche owners will admit to.

Wrong! It is 612 BHP. It has exhaust, injectors, intake, and tune. There is no GTR in existence (that I know of) that makes 612 whp on the stock turbos.

200 hp advantage? Lets see here....

If the GTR is making 612 BHP, that would be a 82 HP advantage
If the GTR is making 612 whp, that would be a 132 whp advantage (assuming PDK makes about 480 whp)

So it doesn't have a 200 HP advantage, not even close, any way you look at it.

Until the GTR went right by him..

Again, for every video you show me, I can show you an opposing result. All these video's don't mean much to me. Quantitative data speaks volume, and a P700 (625 awhp) GTR has trapped over 217 km/h already, and a 600 BHP GTR has trapped 209 km already. These are facts, not opinions or claimed stickers on cars..=)

 

Normally, I don't like to get involved with such arguments.
They end up being he said/she said and somewhat pointless, specially seeing as rarely can someone come up with uncontroversial proof.

I agree with SCvet00 about the nature of online videos. So many variables that true and accurate conclusions cannot be really drawn.

How about PBox Data then? Can that be more helpful?

Here is a side-by-side comparo of my car, PDK that at the time dynoed at around 515AWHP and my friend's GTR that at the time dynoed at 650AWHP. If my basic arithmetics are correct, that's a 135 AWHP difference. (We have both moved beyond that point since those runs were recorded )

This is PBox data taken from his best run and one of my better runs (not my very best as I couldn't locate that).

Now, can I prove that my friend's car dynoed at 650AWHP. No. It is up to you guys to believe, or not. No skin off my nose. Just thought it would be interesting for everyone.

But take a look at not only the times, but distance covered and you will get the full picture. At the top end speed, the GTR's weight comes seriously into play.
When we ran against each other, with no one getting the jump, and we ran five or six times, here's what happened:
-from a rolling start in first gear three times, I leap ahead and he just cannot catch me
-from a rolling start in second gear three times, I leap ahead, he overtakes me in the midrange, then I pass him by the time we are doing three hundred and he cannot catch me.

Guaranteed, I don't annihilate him, but from first gear I open up about three or four car lengths by the time we are nearing top speed and from second gear, I open up about one or two car lengths at the nd of the top speed run.

Here's the PBox comparo, and yes, I have the original PBox files that I can send to anyone who cares to see them.

 

+++1^^^^
Thank u Karim! I was gona call u to scheme in with that slip!!
and a little bit of a write up to clear the GT-R vs turbo PDK issue here ..

 

Unless you have mislabeled the columns, the numbers say the GT-R was much faster.

The GT-R took less time and less distance to achieve any given speed.

Am I missing something here? Oh, the numbers for the 180 line for the PDK are suspect.

xoxoxo

 

To K_DDSL,

Yes we can see on the datas that up to 290kph the 997 is accelerating quicker, but my opinion is the weight is not the issue at that speed, the issue can result from 2 facts:

-the gearing of the both cars in comparison with their power curves.
-the aero which is the first affect after 250kph.

or the both...

BTW, I do not protect in any sort the GTR, my favourite is the 997TT (I have got one), I just try to stay logic

 

Sorry about the 180 line Barry. Miscopied.

The GTR from 100 to 290 was indeed quicker with less distance.
Look at from 290 to 300 what happened!!
In total, the GTR took 28.1 seconds to 300 and needed 1900 meters to do it.
In total my PDK took 28.07 seconds to 300 and needed 1822 meters to do it.

Also, like I said, this was not my very best run, while this is my friend's best run.

I guess what I am trying to say is, with such a huge power gap of 135AWHP, common sense would have you believe that the two cars should not be in the same league. Real world, I ran my friend six times and beat him six times.

BTW Barry, miss yah pal!

 

Salut et bonjour!

You are right. There are a number of reasons.
Gearing, weight, aero. At the top end, the GTR is falling flat on its face.

 

Barry, this is the properly copied PBox comparo:

 

100-200 is not very good for a 650whp GTR. My heavy tip convertible does it in 5,5sec at best and 5,9sec at worse, on VTGs which cannot be more than 600whp

 

congratulations for your videos and 997TT PDK IS GREAT CAR, for the GT-R will be a MONSTER OF PERFORMANCE needs + P800!!!!
my friend has GT-R P850/900hps ans run in etanol, this GT-R is very very fast!!!

see the video of this GT-R 850/900hps in etanol

Weird data.

So what I've learned so far is that a lot of people have fast cars. The driver, apparently makes a difference when it comes to shifting an automatic car. People always badge their cars true, and tell even more accurate truths.

According to the data by k_ddsl - the GT-R will smoke the 997, until 290kph... So unless I'm racing to over 180mph, I'll win.

Got it.

 

Thank you for posting this data.

First of all, your data shows that the GTR is much quicker from any rolling speed to any rolling speed, with the only exception being from 290 km/h - 300 km/h.

Now, lets REALLY look at this data in detail and compare it to the videos posted here..

Your data shows a 650 awhp GTR vs. a 515 awhp PDK. So that means the GTR had a 135 whp advantage. So, with a 135 whp advantage to the GTR, it is obviously much quicker from 100-290 km/h (by over 2 full secs)

Now, let's look at the videos that were posted and compare them to your pbox data. The first video is of a 700 HP GTR (630 awhp) vs. a 550 HP PDK (500 awhp). So that is a differnce of about 130 awhp in advantage to the GTR. So, the difference in whp between those cars is similar to the difference in whp from the cars data you posted. Your data shows that from 100-250, the GTR is much quicker, but in the first video, it shows the Porsche to be much quicker. It DOESN'T make sense.

Now, lets look at the next video....

Spunky shows a video of a 620 HP GTR (550 awhp) vs. a stock PDK (480 awhp). The difference is 70 whp advantage to the GTR. From your chart, when there is a difference of 135 whp, the GTR is much quicker from 100 to 290 km/h, so then it is safe to assume with 70 whp advantage to the GTR, it would be very close (maybe a tad quicker, maybe a tad slower, who knows). But Spunky is showing him in the PDK OBLITERATING the GTR. It DOESN'T make sense.

So, lets talk FACTS and what we BOTH can agree on for certain..

FACT:
A P700 BHP GTR has trapped 217+ km/h

FACT:
A P600 BHP GTR has trapped at 209 km/h

I understand you have a Porsche (and I love them, A LOT), but don't let brand loyalty BLIND you. The vidoes posted in this thread by the original poster and the Spunky don't make ANY sense.

 

Spunky, this is for you from the GTR owner confirming that he beat the PDK with 612 BHP..

 

All I can say is that this is one slow GT-R. I have raced a SPI P750 Tip with my GT-R and was surprised at how on every shift, I would creep ahead, then he'd gain a bit, then he'd shift and I'd start to pull. The tranny is a big equalizer in the GT-R and the Porsche's PDK has solved this problem.

IMHO, I believe that GT-R has a very conservative tune. If a good tuner got a hold of a GT-R with this hardware, it should logically, pull on your 997TT PDK. But that is most definitely a win so I'd feel very happy if I were you congrats!
