I suck at the quarter mile but I will make it a point to go to the strip in spring. Kinda hard living in the Pacific North Wet. Road courses are on for sure.
You don’t have to be good with the RS5 
Launch control, ESP/ASR off, full throttle and keep the steering wheel straight. Lol!
When I went 12.75 @ 108.36 it was +300 I believe. April 6, 2012 at 3pm at Toronto motorsports Park.
When I went 12.82 @109.9 it was - 1050. There was a 12.6 in it that day if I had been smart enough to lower pressures. Car just spun like crazy all day. Here’s one of those runs

There are two other stock rs4s that went pretty much what I did. Jnaut went 12.84@107.9 and Richard jeans went 12.87@108
Apr went 12.43@ 110.38 and that is the rs5 record. I have seen like 5 other stock rs5 times. Magazines have it anywhere from 12.7-12.9.
Some dude at Englishtown 12.9 @ 107

Some dude in Australia 12.7 @ 109 and 12.44 @ ??? (MPH is broken but 1/8 was same as the 109 run)

As I said I think dsg and that extra 35hp helps, but it’s not going to be 0.5 seconds if it’s a good drier in the rs4.
Edit: 3:43 pm. Da was +281 feet at 4pm.

The red one with with the kit going for $51k
Richard Jeans had a full milltek on his run. Edit: I spoke to Richard and only mod on that run was Michelin Pliot Cup tires which don’t seem like much of a mod when you look at the 60’.
Jnaut was about .4 seconds slower than a stock RS5.
I don’t put much credit in magazine 1/4 mile times. Every magazine had the RS4 at 13.2 and B8 S4’s in the 13.4 range.
Also Richard Jeans car is lighter since it’s non US spec. About ~100lbs.
Also some other things to remember. The 20" wheels are def heavier than the RS4 wheels, that RS5 run at E-Town was +1000 DA and 75 degrees.
The other guy ran 12.44 and APR ran 12.4 which seems pretty fair as to what a stock RS5 is capable of.
Tough question… The primal desire for power in me say get the biggest baddest blower immediately! But since I’ve owed the M3 I’ve gained an appreciation for the overall balance of the M3 package. Though I do feel more power could be fun, in certain areas, I worry that it may throw-off the overall balance that I’m beginning to really enjoy… I would image the same can be said for any RS model as we’ll…
It is just lulz to compare performance of any auidi, even the R8 v10 plus, to a GTR. You cant, however it is funny how the GTR was brought up when I just recently went down to the Nissan dealer two days ago to seriously check one out.
I came to the same conclusion as 81bear did, the fit and finish, rear end, and interior just was off. I just don’t like them to make it my daily driver, no matter how fast it may be and how tunable it may be. I will keep my S5, still love everything about it.
The only upgrade I would go from here would be a TT UR R8, something retarded like 1200hp on pump.
I don’t care that a stage III+ RS4 is as fast as a stock GTR or faster than the 2008 GTR (which would be a more fair comparison at 11.6 quarter mile) it is simply a much nicer car overall. If all you care about is performance then GTR is your car. It is more tunable and cost effective to bring that GTR to a level the RS4 will never touch with over 1000 hp on pump.
Agreed… I believe it’s the high compression engine that will be the limiting factor! You could do a full engine rebuild but it’s very prices especially compared to other platforms i.e GTR’s
- 1000%
I’d be willing to settle for a V8 R8 S/C’ed if I can do consistent 10’s in the 1/4 mile on pump (lol… Can’t believe I’m saying I’m “settle” for an R8)
Audi RS4 = $35,000 for a good one (not a great one, not a beat one)
JHM Engine build with sleeved block = $15,000 (guestimate)
JHM stage 3 supercharger kit = $14,000
JHM Exhaust and Stage 5R clutch/Flywheel = $5,000
This will be good for approximately 700 WHP, and if they introduce a bigger supercharger, even more. They are already working on this, with teh V3 Si getting pushed to its limit on stage 3.
So $64,000 .
What’s going to touch that for $64,000? Is there a GTR in North America even for sale for that money? Never mind the $10,000 or so in mods you will need to catch a stage III RS4. And nevermind the fact that you’re driving a 2 door, somewhat ugly, impractical, rickety JDM car with probably 100,000 kms on it.
You’ve totally lost me… I was saying the cost to build a NA S65 engine (M3) is about $15k where as building a GTR motor is about $7-8k (half the cost).
To your point you can get a GTR in the mid $50’s (US) + $7kish in bolt-ons will have the GTR in a position where it’ll out perform the hypothetical RS4 car in your scenario. It should have about 40-60k miles on it and it probably be an 09-10 model year. Ugly is subjective. Rickety probably…
An example of the GTR in my scenario:
The package I’m referring to is SBD700 kit ($5k). I’d also include ported intake manifold for $1,200 (not included on the 10.5@130.5mph below)
http://www.gtrlife.com/forums/topic/91847-new-pb-93-octane-oem-turbos-10525-13056mph/
This shows the SBD700 kit going 10.0@136mph (on E85 but is missing the ported intake manifold which should equal out)

How about exhaust? I doubt anyone who is going to spend almost 30k on a blower and built motor is gonna be on stock exhaust.
At 700whp will the transmission hold up? Might need a rebuild as well as stronger axles.
It’ll probably need motor mounts, diff mount and trans mount as well.
Suspension upgrade at this point is a must, as well as some type of brake upgrade. Basically you’re putting down 2.5x more power than stock.
He included exhaust (exhaust + clutch for $5k).
Brakes and suspension is a personal choice but not mandatory for straight line power.
All mounts added up together don’t even equal $1k I believe.
As for axles and transmissions, can’t speak to that. I honestly wouldn’t know.
Didn’t see the exhaust, my bad…
Brakes and suspension are mandatory when you’re pushing 700whp+
The trans and axles will not hold up to multiple 700whp+ AWD launches.
Tell me why they’re mandatory. I would personally upgrade them myself, I even have for way less power but I don’t see them as being mandatory. And last I checked, the RS4 had 8 piston brakes stock. Maybe start a new thread 
As for the trans and axles, probably but untested.
Watch the launch of the race gas APR RS4 and anyone with any drag racing experience can tell you that the car is in dier need of suspension…
The stock brakes sucks and if you plan to make 700whp I assume you want to drive your car hard, correct?
What do I know thought lol, what I’m trying to get through hear is that building a car is never that simple. It’s never as easy as listing three mods, ordering and installing. There’s always a million and one little things that add up and end up being a decent amount of extra cash…
Guarantee you that you won’t be able to drive a reliable 700whp RS4 for under 50k in mods, it won’t happen.
Seems most of the super power cars I’ve seen are pretty soft suspension wise.
Besides the Apr car had stock cat back and suspension and went 10.6. I think it’s doing just fine. The suspension was not an issue.
I thought you were saying ‘just buy a gtr’ as a financially better option than a motor build.
Those gtrs from America with mods are interesting. The first one is trapping what a stage 2 RS4 does, never mind stage 3. The second one is slower than what I think the built motor rs4 will do.
And they are gtrs .
What year are those by the way? Are they early models? I was under the impression that the gtr was a bit of a China doll in the early year(s). If you’re showing 2011+ gtrs with modest mod lists, shouldn’t you be starting at around $80,000 for the car? Won’t the early cars need a good bit more work to keep up?
The 10.5 car is a 2014
http://www.gtrlife.com/forums/topic/89958-my-pearl-white-2014-nissan-gtr-black-edition/page__view__findpost__p__1248896
So that’s what… $125,000+mods?
The second car had drag slicks, a carbon fibre trunk, a spoiler delete and who knows what else.
So I think your reply to my off-topic reply is off-off-topic 
The 10.6 run had no Catback and high flow cats.
Suspension IMO def held it back, it needs to be stiffer- it’s sloppy.
