hey, 81…did you guys get like 20 passes in? That was a LOT of timeslips.
Closer to 27 runs.
HOT LAPPING FTW!!!
each? WTF!
I would like to see that. as of now. these cars have a artificial strong hold on the 11’s. that strong hold comes at the expence of a fuel that no one runs unless there going to the track. So to me while impressive its not real day data unless you run it how you drive it on the street
I had the car tuned at 2200 miles and it hasn’t seen a drop of anything lower than 100 octane since… I run 100 in my Mustang and had run 100 in my B5 exclusively… They aren’t daily drivers but do get driven to the office and for errands on occasion… We have stations around me that sell 100 and higher at the pump so that is what I choose to run… Yes I am the exception but my car will run the same times on the street as it does at the track…
B8 hater! lol
I know what you mean. The one exception might be primetime who runs race gas full time, but I know what you mean. It doesn’t take the accomplishment away…let’s be clear about that. It just makes it tough to compare platform to platform when the gold standard for one platform is race gas, while the other might be pump gas based. put those two cars side by side on the highway, when they’re full interior and pump gas, and it’s a different story vs. the timeslips. I like looking at quarter mile times to see where car vs. car stacks up, so I don’t dig the race or stripped times really.
The B8 race gas love is very similar to the B5 days. Alll of the fast B5 times, and I mean ALL of them, are race gas or stripped cars or both. The fastest full interior B5 S4 I believe is jaybquick from JHM. He ran 11.1 @ 131 on race gas, but full interior. They even shot a one cut video of the run then opened all doors and the trunk so you could see. On pump I think Jay ran 11.5 @ 12X. Not sure about guruman but he was most certainly on race gas when he went 10s. marc (TenSecondS4) was race gas and had stripped everything from the car till it weighed 2800 lbs. The polish guy’s car is a race car so that’s irrelevant. So that’s it?
This is interesting…I wonder what the fastest full interior B5 S4 time on pump gas is? I bet it’s that jaybquick 11.5 time. That just shows you that the B5 and the 4.2 cars really aren’t that far apart. It really puts the last 24 months in perspective. We went from everyone worshipping the B5 whiel the B6/7 struggled to break into the 12s…to looking forward to Dan @ JHM"s RS4 getting supercharged to potentially take down the fastest B5 pump gas time ever.
It’s funny because nobody has run any of the fastest B6/7 S4/RS4 or S5 cars on race gas. Everyone’s on pump. It’s interesting how the B8 guys immediately embraced race gas. I think Primetime is the big reason…all the other guys saw his success and wanted to duplicate that success.
ok Ill give the nod to prime. If you indeed run pump race all the time them you fall into the class of true hardcore racers as thats how my mopar runs all the time C16. So actually more proper nod to you. Thats actually impressive.
I supose to be more clear I don’t like the guys who goto the track with race gas take out the passenger seat back seat and then say they have a XX.XX fast car.
I supose the beter way to put it is I wonder if in street trim the B8 is as impressive
Oh its impressive on pump too
There are a couple of low 12 second pump gas times. Let’s not forget…this is just a $50,000 car and with pulley, tune, hfc and exhaust ($5000) its a mid-low 12 second car running like a stock $70,000 m3/rs5/c63. Maybe a hair quicker.
That’s pretty awesome. Can’t take anything away from that 3.0T…its excellent. The torque curve is a massive difference maker even though the b8 forums obsess over whp numbers. Did you see my thread about the 3.0T A6 loaner we have right now? Huge, heavy, soft, mooshy trans…and still fast. Raced an S5 last night and it was closer than he would have liked I can assure you. I was surprised.
i can only dream of what a fully built bottom and top end 3.0 with a tvs 1650 and a 100 shot on c16 would be like lol
^^^Do you think it will ever go that way? I mean with the B5, the built motors happened because there really were no other Audis that could push the envelope performance wise. However with RS4 , RS5 shipping with already forged internals and stock headers and great heads and cams, and from the looks of it 500+whp from the stock motor will be safe, I have a hard time believing that someone would drop $20,000+ supporting mods on a V6 3.0 build. Maybe I’m just missing it.
Also, the 1650 is not likely to even need a build. Of course it’s just a diagram on someone’s computer at EATON so we don’t even have a compressor map (thus I’m just guessing) but it looks like it will maybe flow around 950-1000 CFM, or about 600 at the crank. That’s 500 whp at 16% drivetrain loss…and I’d have a hard time believing that Audi wouldn’t make the forced induction 3.0 able to handle 500 whp if the high revving 4.2 FSI can. Different applications of course, with the 3.0T being in a bunch of ‘calm’ cars while the 4.2 FSI high revving version is just in the RS and R8…but it would be weird if the FI motor wasn’t as strong.
If you go built, think 1900, although I’m not sure how effiicient that will be from such a small displacement engine. I don’t know enough about that to guess if that’s a problem. Anyone?
the 1.9 is a lot of blower, its gonna to suck a lot of power spinning it… but then again Kenne Bell makes a 4.2L blower kit for the 6.2L Camaros so a similarly massive blower to motor displacement. It depends on how its geared up (overdriven, underdriven). I’d rather just leave the stock blower on there and put a c-s/c somewhere and have it blow into the stocker.
It will also depend on how well the heads flow and where it puts you for a boost level. Its tough to guesstimate since blowers are trial and error (pick blower, pick hp you want ie cfm or mass flow, pick pulley ratio and spin it up).

Are you kidding? Holy crap.
and thats not even a really big blower, a GM 6:71 is 339cid for the smaller version and 411 cid for the larger version… an 8:71 is 436 cid per rotation. So like 5.6 to 7.1 liter blowers.
^ jaw on the ground just laughing at that prospect right now. . .
and top fuelers run two 8:71s typically iirc (maybe 6:71s) that are overdriven (so already pumping in 14L of air for every rotation, the blowers are then spun faster than they cram in even more air)… the motor is only a ~500cid or ~8.2L which means it consumes that much air volume every two rotations or 4.1L per rotation… roots blower so it externally compresses to about 50# of boost all in all.
Wow. And I though a 2.8 KB was big
