reeeeer
Are you trying to say your wife has some nice curves?
Damn builtmotorelitists…fuck
I picked a winner :o
Well this escalated quickly Haha
lol… I think Saki is going a little overboard with the instigating.
Haha maybe a touch, but this is why I’m a big fan of AR, good topic with a good discussion, it might get alittle heated, but glad that everyone here can take a step back and realize were all in it for the same reasons, and then come back to the table with even more to discuss. It really is a win win for everyone!
I do have a couple questions and I appologize if they come off noobish, just these are newer things for me;
Timing upgrades? Is this mostly to do with the S4 4.2? I haven’t seen or heard to many issues with the RS4 4.2, regarding timing components, although I might have completely over looked this. I’m guessing these beautiful JHM gears we see are to get rid of the adjusters?
With the RS4 4.2 built motor program, what exactly is going to involved with this? Pistons, rods, new heads, new valves, any new component’s for the timing? Obviously a sleeved block, but wanted to see of what else was going to be beefed up, considering that these motor did have quite the jump over the S4 motor, in terms of strength. Also wanted to see if the stock Rev limit would be kept, increased or decreased?
Yeah the timing upgrades(mechanical cam adjusters) that we’ve been talking about would be for the S4 4.2. I tried prying some info out of Dru about the built motor program for the RS4 but he wasn’t really giving anything up since it’s still in it’s infancy. I’d imagine it’d be similar to the S4 built motor program meaning sleeved block, forged pistons and rods with the option of doing the heads as well with new valves, springs, and retainers. I also tried to get info on the red line for my S4 and I haven’t been given an answer yet. Probably will have to wait until I pick up my car or one of the other guys who gets their cars back first posts the info. I’d imagine it would increase if anything.
just having a laugh
It’s cool… That picture you posted gave me a good laugh.
With a centrifugal blower that JHM gears accordingly you don’t need to worry about trying to spin 9k RPMs. Just think what a mis shift at those engine speeds does…even to built motors. I think they should leave the limits right where they are, pushing beyond that adds a ton more stress to components.
If your making a shit ton of power from 3-7k, you’ll be happy, trust me. On the stage one stock motor kit that blower was limited by the tune dramatically. Now hopefully CV can let it breathe with the built motors! Saki’s lucky ass actually got to ride in these different combinations maybe he can chime in on the power throughout the rev range.
Rx and MDUBZ… don’t forget the cameras! ;D
I got alittle info out of Dru, and seems to be very close to the S4 development program, the ability of getting a built block and just running that, knowing its virtually bulletproof, then later on pushing some air through it would be awesome. Im thinking for the RS4 we would get a return to the stock Revlimit, which really isn’t much difference, just wonder where it set at, as for the S4 setup not to sure what you guys are expected to see, probably a slight bump at least.
Completely Agree, I was a big fan that the Stage 1/2 on stock motor was turned down alittle, just interested to see where JHM sets the limits now that the block and heads are going to be built, probably no higher then stock.
mis-shift at those speeds I don’t even want to think about… yikes…
stage1 was held back quite a bit, and I know that saki said stage 2+ was modified GTR territory which crazy, but with a built motor and actually allowing the motor to breathe even more, it just gets even more interesting, I have trouble wrapping my head around how far there planning on taking this at the moment, although i do plan to own the experience sooner or later.
This.
Yes, this discussion is mostly the B67 S4. I haven’t heard much about the RS4 timing components. I know that Audi revised them a couple of times and perhaps later model B7 S4 and RS4 are in better shape. I would like to hear about that though.
The reality is the timing component failure in the B67 is certainly an issue but it’s not like 100% of B67s at 100,0000 miles will need a motor pull and chain job. We have heard of probably 50 cars having this done…out of what, 40,0000 on the roads? If the same type of ratio (all guesses) applies to the RS4 that would mean that 2 in North America have been done. So we could easily have missed it. Maybe JHM can comment on RS4 timing components.
The RS4 is definitely having upgraded rods and pistons made. I held them in my hand in California. Not sure on the valvetrain but why wouldn’t you really if you’re tearing it down. Although it’s strong as hell stock to support the insane RPMs
Jason said that regarding the rods…the stock rods are very strong, but why wouldn’t you make them bulletproof while you’re in there already? Imagine spending a fortune for pistons and sleeved blcok…and then a rod fails on you at 600 whp? Wouldn’t you feel stupid that you saved $1500 and destroyed a $20,000 engine?
Yes I was lucky. Stage 1 and stage 2 built S4, and stage 1 and 2+ RS4.
The feeling is pretty cool. Hvaing put 150,000 KMS on B7 S4 stock and modded…and B7 RS4 stock and modded, it was cool to feel the changes.
Stock B7 S4 was nice and torquey and fun. But when you JHM tuned it, it really made it much more responsive and way quicker. I picked up what…5-6 MPH in trap speed with my tune/exhaust. But it still fell off up top. You’d get to 6000 and start to feel it. Not dramatic, but you felt it.
Then I drove AXEL’s stage 1 S4 and it felt WAY different…car just pulled forever. It really runs away from you compared to NA. You can just feel it and then you have to watch the tach because you get up there quickly without the signals from the fall off of power you had when NA. My best trap ever was what…107 in my B7 S4. AXEL’s car trapped 114 - 116. That’s a huge step
Interestingly though the stock motor stage 1 S4 kit is SOOOOO held back up top. But it doesn’t feel it compared to NA. It feels awesome. I believe the tune has throttle down to like 40% at 6000 RPM even if your foot is through the floor. Protecting the motor.
In California I put probably 100 miles on the JHM stage 1 supercharged B6 S4. It had headers and was afrigging blast. There was another level there vs. Axel’s car, primarily because of the headers and the tune for headers stage 1 giving it a bit more. Not dramatic, but definitely quicker. That level was evident in performance testing, as well as on the road fully loaded. We had Dan from JHM, CountVohn and Me in the car. The three of us weighed around 700 lbs. Then we had some luggage in there as well. A guy in a burnt orange SRT Challenger pulled up on us, and it was on. Quick downshift, let him get beside us with some momentum for him and then pin it…and there was no chance for him. It was hilarious. At the end of the pull after we slowed down and he caught back up, he was giving us the Wayne’s world ‘not worthy’ bow. We all had a good laugh.
The stage 2 S4 I was in I was just a passenger, and it was going through breakin so we couldn’t exactly take it through the roof, but pulling through the RPMs was excellent. I have some 60-90 MPH data (PBOX GPS BASED) on every one of these B67 S4 configurations and I will just say none of the others are anywhere close to the stage 2 S4…and that’s on a bitch tune.
Yeha, RS4 Stage 1 is pretty awesome . A bit quicker than any stage 1 S4 setup, headers included. Maybe a little more power. Very fucking impressive.
They don’t touch the rev limit. There’s not a huge benefit to trying to out engineer Audi when it comes to the rev limit on the RS4. THe amount of $$$ and engineering that goes into preparing the 4.2 FSI to run up to 8200 RPMs is staggering…so pushing it to 8500-8600 RPM on stock motor is nuts in my opinion. I am not sure what they ’ are doing on the built motor program but I don’t think they’re touching it.
Yea it’s crazy that the throttle is shutting down big time at 6k and onward, but Count said as far as power, to just keep taking it to redline b/c with the blower, regardless of the throttle plate, it just keeps making power as you go up in RPM.
Its kind of an exponential increase in airflow as the RPM’s go up too, the built motors getting to keep the throttle plate open the full time will be a huge advantage right there alone.
Saki, that was seriously an awesome experience you got. Even the guys getting the stg 2/3 S4/RS4 may never get the opportunity to hope in as many different variants as you did on that trip. Kinda the downside of being a relatively small performance base car.
+1… Sounds like he had a great day or couple of days. When I go fly out there to pick my car up I’m going to make sure I follow suit and at least take a ride in everything I can. That’ll make the trip out there even more worth it.
does the performance gap between the 2 cars narrow as the stages increase? Obviously a stock RS4 and stock S4 are quite far apart… it sounds like they are closer when they are both stage 1… is it even closer at stage 2?
I think the RS4 will generally always have a 1/2 to “1” stg lead on the S4. But the “stages” are also fairly relative terminology.
It’ll be interesting to see where both cars are at when both are Stg3.
Also don’t forget the gearing and higher redline of the RS4 will always be an inherent advantage.
