An A5 2.0t K04 is fast... I will run with the S5 and RS5...stock.

That is all.

In stock form, you don't think so? It sure feels like it. If not, I'm going to be delusional, too late to find an S5/RS5. You know I love when you chime in...

I think of it like this, in 1983 I ran a 4.7 40 as a 230lb LB, now LBs run 4.5, looks like 2 tenths to me. I could run with them...

I mean power wise, it could potentially put down slightly more power to the wheels than a stock S5, but that doesn't mean it will be faster. If it's a DSG S5 I think the transmission would prove to be a big difference maker. As far as going up against a stock RS5, I would highly doubt it unless you were racing at a high elevation. At 6500 ft. elevation a stock B8.5 S5 and RS5 are remarkably close on acceleration, but the RS5 will still pull away. So, you'd probably have to go even higher than 6500 ft before a K04 A5 would stand a chance against the RS5.

I think this calls for a Dragy to verify results.

Lol...

Just remember, "it's not a lie, if you believe it." LMAO!

That's not an achievement....b8/8.5 rs5 are slow. I own one lol. I love it but it isn't a fast car these days.

I think an RS5 would eat your lunch.

But let's talk numbers. What kind of power & torque would you say that you're putting down with the K04? I mean, an RS5 has 450 HP off the showroom floor compared to your 211 HP, so I hope you at least doubled your HP with that K04 swap.

They aren't slow compared to an A5. It's all relative....

Numbers wise.. a K04 A5 could keep up with an RS5. Both of these charts are with 93 octane. The A5 has more torque almost the entire time throughout both power curves. Yes the RS5 makes more HP starting only around 5k RPM. Combine relatively close power figures with being with being approx 500lbs lighter iirc, an K04 A5 sticks right with an RS5.

When I go on cruises with my local Audi group, one of the guys with an RS5 barely pulls on me around 30-60mph. It's really only after 60mph I can see him separating.

So you're not actually keeping up with him is what you're really saying.

Okay, but let's be real here....even with a K04 swap and some associated mods, the A5 isn't going to make nearly the HP of a stock RS5. The additional torque is nice, but the RS5 will absolutely rip in the upper rpms and on the top end with it's much higher horsepower. And it's nice that you can almost keep up with your buddy's RS5 from 30 to 60 mph, but in a typical drag race, we're looking at more than 100 mph and the RS5 will easily walk away.

But hey, maybe Mr. A6Sport was just claiming that he can run with an RS5 up to 30 mph. Then I'd have to agree with him. The RS5 obviously isn't made for low end torque, it's made for high rpm horsepower. And last time I checked, once the RS5 gets to high rpm in 1st gear, it stays there banging shifts through every gear. In other words, it's in the sweet spot pretty much the whole time. That's why an RS5 runs 12s bone stock and an A5 runs like 15 seconds bone stock. You just aren't going to turn an A5 into a 12 second car by adding a K04.

Back in the late '60s/early '70s, there was a similar (but more realistic) comparison between the Dodge/Plymouth 440CI engine and the 426 Hemi. The 440 had more low end torque and the Hemi had more horsepower up in the rev range. So, a 440 could step out in front of the Hemi from the start and then shut down before the 1/4 mile mark and "claim" victory. Point is, yes the additional torque will give you the advantage down low, but you're not going to keep up over a longer period of time.

Now, if we were discussing a modded 3.0T ….

Yeah, that's true. Torque gets you off the line, but horsepower is what pulls you the rest of the way. I see it all the time at the track. My buddy has a high-HP modified Supra and he gets killed out of the hole by any number of track cars. In so many cases he ends up blowing by them around mid track and never looks back. The true indication is quarter mile trap speed. HP always beats torque when it comes to high trap speeds because torque really doesn't matter there....it's all about horsepower.

What track do you take your car to? I'm in the same area and have a slow A5 with a couple of mods. I'm certain that my car isn't as fast in a straight line as an RS5, but I'm curious as to how much slower it is...or is it?

I used to go to Englishtown, but they recently shut down. ATCO isn't that far, so there's an option. Go ahead and see what you run. You don't need an RS5 to compare. Just see if you can get your car into the 12s or not. Keep in mind that it will take a lot for an A5 to see 12s.

BTW, I don't have an RS5. I also don't have an S5. My car is an A5.

You also don't need a drag strip to see how fast your car is. If you have a safe, isolated, reasonably flat road nearby, buy a Dragy for $150 that you can use over and over again. It would be especially handy and useful in the event you plan to do more mods, so you can determine their effectiveness.
