Just beat an S7 2/3 runs with my diesel A7 :)

[BenMTL]

This happened last night....3 red light runs, each running for about 0.25 miles.

I beat him the first and last run, he won the 2nd one. I was really surprised until I researched his engine....We are not THAT far off. We were both reeving at the lights, ESP off, etc.

S7:

420 horsepower, 406 ft lbs, twin turbo, 7 speed stronic, v8, 4.0 liter, petrol

My A7:

 
380 horsepower, 550 ft lbs, twin turbo, 8 speed ZF tiptronic, v6, 3.0 liter, diesel

It was a real S7, exhaust, trim, wheels, everything. Just cost him a lot more than me so I am surprised we are so close, if not me faster on short runs

[flyfishing]

if there was a biturbo diesel here i would buy it over an s7 and tune it :)

Exactly what I did haha....Because no S7 here :)

Video? I’d like to see this in action!

Wasn't recording unfortunately, and was at night so not that you would see much anyway haha....Nice to catch an S7 here by day and try again....Closet thing to me I've raced to date.

SQ7 owned me last week!

[pez81]

No offense dude but I doubt it. S7s stock pull hard unless you've tuned yours massively I don't see it. Might have been a lookalike or he wasn't giving it full beans
Could be wrong but seems unlikely

also the s7 does not have a ZF trans, its the S-tronic

S7:

420 horsepower, 505 ft lbs, twin turbo, 8 speed ZF tiptronic, v8, 4.0 liter, petrol

My A7:

 
380 horsepower, 550 ft lbs, twin turbo, 8 speed ZF tiptronic, v6, 3.0 liter, diesel

Yeah, nor does it have 505 ft lbs stock.

[richib86]

also correct! somehow skipped right over that lol

[BenMTL]

1) Yes my car is tuned (but only stage 1 software)

2) The numbers are from wikipedia, blame them if not correct I had no idea what the S7 numbers were, so googled them.

3) 100% was a real S7


Easily explained, he had +40 hp but I had +50 ft lbs so on short distances I'll win every time. I'm not even sure how he beat me that 1 run tbh.....

Must have been short distance is my guess. Felt good though I'm sure.

The V8TT S7 is also a little more than 100lbs heavier than the A7 3.0TDI V6 when both are stock. Then consider aftermarket wheels or brakes, tunes, intake temperature, driver weight, fuel load, trunk load, and you can get a meaningful weight difference between the two cars in the A7's favor.

There are so many variables to this so it is believable that A7 tdi takes the S7.

Also not sure if any of the spec power figures are correct as mentioned. Looks like usa S7 is 406ft-lbs. If you have 550ft-lbs that is significant.

Oh wow haha, big difference....This is making a lot more sense to me now

S7 was a lot more expensive option here, guess there was no need for it

He's saying 1/4 mile- all things equal I'd be shocked to see a Stage 1 TDI keeping ahead for the entire 1320- but who knows, we have nothing to compare it to, no track info at all available that I can find anywhere.

My bad :-)
Tuned diesel cars can pull really strong no denying it.
Had fun woth a 335d tuned due to the plumes of black smoke pouring out. Nutter was driving high speeds with a space saver I almost soiled myself laughing.

my guess, first race he was not racing. second one (which he won), he realized you wanted to race, so he spanked you. third pull, he figured he already showed you, so was not racing again. the s7 is highly underrated, and stock likely has closer to 460-480 hp. torque is only relevant in this case in first gear, after that, the s7 is in a higher rpm range, so since hp is a function of torque on time, and the s7 is in higher rpms, the s7 will kill the diesel a7. no offense, diesels are cool and all, but a tuned a7 tdi is not pulling on an s7 in the 1/4 mile. the s7 stock will run 12.0 @ 110 mph. the tuned tdi is likely going to pull around a 13 second 1/4, maybe 100mph.

I don't think you read the topic so I can't read the rest of your comment either.

Do your own research or pull up to me on a red light and see for yourself (If you're stock)

A better transmission (stronics are hated here, all hybrid clutch systems are for that matter, including DSG), almost 150 ft lbs more torque, and 100+ lbs lighter....Now im confident I'll be able to beat every other stock S7 now for that matter as well, even if I have 40 less hp (small difference). Our 0-60 miles times are very very similar as well.

[Dasquade]

So? :)
Don't get me wrong, happy for you and yes, i used to be a diesel driver (all my previous car were). Especially the 3.0 biturbo's can pull hard (high torque down low).
Never the less, i bet he was bone stock, where as you have stage 1 and were detirmened to give it your best).
I'm sure if the S7 engine was warmed up, equally tune staged (1)....you would of loved the V8 rumble past and away from you ;).
No offence, no mather what, both very good engines! Still kinda miss the fuel effiency of my previous diesels, but Europe is banning diesels (reasons why i sold mine).
Thanks you goverment for the 'light van' roadtaxes, loving my V8TT van ;).

Offtopic: but highway police and local police here in Belgium have been using the A6 3.0Biturbo's for several years here :). They recently bought a new batch of them....(they aren't tuned i think :p ).

Sorry, I don't see it. Tuned A7 3.0TDI to 400hp and stock S7 not using launch control

Stock pre facelift S7 is a quite slow car, but with the EPL tune it beats the stock RS7, I have done it many times.

[AWDYEAH]

From what I’ve read from APR’s test data, pre-facelift C7’s have the same output as the post. Audi was conservative when quoting what the output was. Manufacturers do that all the time.

[DGVR6]

It’s about a 10hp difference

A Tuned c7.5 on 93 has 4hp less than a c7 on 100 but makes 4ftlb tq more.
It gets better as octane go up for the c7.5

Maybe a gearing thing for more horsepower and less torque on the c7.5, so technically same power.. just something is happening around the gears to shift the numbers over id imagine

[BenMTL]

Yes I was surprised as well, but now looking at the numbers it all makes sense

Next target is Stage 2 or 3 and use the RS7 for comparison instead of S7

[cobrario]

Stock pre facelift S7 is a quite slow car

PFL Cars run virtually the same 1/4 mile times as FL cars- generally around 12.2-12.3 @ 112-113... which I guess is slow?

but with the EPL tune it beats the stock RS7, I have done it many times.

No EPL Car I've seen has bettered my stock times or traps (several other stock RS7's have posted 11.2X at 122/123 also) if you've beaten "many" RS7's from a dig well done; however, I'd say with a driver mod to the RS you'd be staring at taillights.

He's optimistic that's for sure.

the videos above show tuned 3.0tdi running 9 seconds 30km/h - 140 km/h. the stock s7 in the video is doing it in 7 seconds. case closed. s7 faster, not even close.

No need to be jealous friend Please see above numbers.

Oh and I hope you realized there are 4 "3.0 tdi" A7 models right? And that video is not my car, not my engine, and not my tune, all wrong.

[flyfishing]

theres a TDI and theres a bi turbo TDI. mmmm bi turbo

[Dasquade]

Don't become cocky please BenMTL. Again respect for the biturbo diesels....but what was your point again? You semi won with a tuned 3.0biturbo diesel versus a stock S7?
We all know the 4.0TT in the S is very downtuned :), so is diesel but maybe you should try yours against a stage1 S7? :)
Just enjoy your car :).
*yes i debated between a 3.0 biturbo diesel or 4.0TT. Ended up getting the little 'detuned/sleeper' brother of the RS6 (S6) and converted it as light van (no backseat) for super low roadtax use.

No, there are 2 additional engines available actually in terms of A7s at least, those are only 2/4.

Just fucking with him because it seems to really hurt his feelings hahaha, love it. Numbers are facts and don't lie, I was personally surprised with the results, but that doesn't mean you can deny them.

Yes probably Stage 1 S7 will win, no idea haven't tried but that is my next target.... Should be interesting

Your diesel A7 will be destroyed against a proper s7 stage 1 ecu-tcu tuned. I have the EPL stage 1 ecu and tcu, and have even beaten stock rs7. V box showed 0-100, 3,8 seconds with the stage 1 ecu + tcu tune.

"Probably"? You do realize how much extra a stage1 or 2 does on the 4.0TT (at least i know my stage 2 pulled just under 170hp and 330Nm extra).
Never the less, drive safe and just enjoy :).

The video I posted above was a 3.0TDI with more power than yours and still slower than a stock S7 that wasn't even using LC.

I'll believe it when I see a video. The burden of proof is on you friendo. If I am proven wrong I will gladly concede and pray we get that car soon in Canada.

that is what I was saying above. in the vids, the tdi goes 0-140 in 10 seconds, the stock s7 does it in 8 seconds with no LC. I know Ben thinks he is trolling me which I find funny. I am not a diesel hater, I also have a diesel merc with kleeman KD box, and I am fully aware of unleashing additional diesel power, but I am also aware of diesel limitations. all things being equal, the bitdi is 50-100 kg lighter than an s7, which is 2.5-5% lighter, so in terms of power to weight ratio, 380 hp will not cut it. to be equal, the s7 would need to have no more than 400hp, and we all know it is closer to 480 bhp. in order to keep up the bitdi would need more like 450 bhp, not 380.

now, all that being said, the bitdi is a really cool car, and one I wish we had in Canada. I am a huge fan of diesel torque and efficiency, and even looked at diesel a7s before buying my s7. unfortunately they only come in one flavour in north America, 3.0 tdi with 245 bhp. not bad, but also not particularly stunning, and coming from my b8.5 s4 with chipwerke piggy back (and an M5 prior to that), the performance was lacking. perhaps a bitdi would have been different. I don't know, as I have never driven one. also not sure if I would want to try to start one in my current temperature of -36 degrees!
