thoughts on the B8 S4 game

B8 S4
#41

sak, i was just bringing this topic up because i know you, brian and a few others are up on your shiz on blowers from the b6/7’s. that and with FI cars its the usual progression so at some point in time be it soon or 3 years out, it’ll happen.

don’t give me that light weight bullshit, we all know the one company that can do it, won’t do it… IM CALLING YOU OUT DAN!! lol. my last convo with dan i told him id be sending him my brakes at some point both for the stock setup and for the rs5 brakes I’m running. the rs5 rotors may happen really soon as i have an annoying ass shimmy when I’m on the brakes, i think they may be warped.
im also really hoping that the s5 flywheel setup will truly work on the s4 as well.
what i would REALLY REALY REALLY like to see is some sort of drivetrain mount, especially one for the diff, like the apikol application for the b6/7. the car has a fair amount of DT slack which worries me after APR said they blew the sport diff right off the mounts in some of there testing.

now the exhaust… its a touchy subject. this motor sounds like complete shit for a DD when its all opened up. we all know danny at FI knows what he’s doing and he gave up on this exhaust cus no1 was pleased with the amount of interior drone and to add resonators would conflict with his design. i think the manufacturers gave up on that front and made what was most pleasing to the ears. the FI setup with the headers made me feel like i was listening to the brown note and shitting my pants could happen at any given moment. and tho its subjective and still up for debate, the butt dyno feels like the miltek runs stronger than the FI setup. and i still feel that the 2.36" diameter of the miltek helps retain some crucial back pressure with this car, maybe its in my head?

yeah, it’s easy for a V8 to sound decent so it’s easy for us to forget that. Good point.

With the 3.0 you’ve also got to be careful as the smaller 6 engines have drone at a different RPM which can be unbearable (highway cruiseRPMS from 2-3k) whereas the 4.2 V8 engines drone 1100-1900 which is never really used. The E46 M3 guys had this problem…lots of aftermarket exhausts were chucked as a result. I wonder if the 335 guys have the same problems, and what they’ve done to make it bearable. Resonators don’t really do much for drone I’d think. Rather they might just exacerbate the problem.

As for JHM stepping up, their clutch and flywheel for the S5 should be awesome. I do remember being there when they took apart an S5 at a meet and the JHM guys were all looking at the S5 C/FW setup like it had come out of a spaceship. It was definitely weird, explaining why there are no options for the car really.

i mean… who the hell would think its a good idea to put a half shaft between a clutch and flywheel… i mean seriously, why does audi have to give me this damn run around lol

hey, is the S4 exactly the same? You’ve had your motor out I think…send some pics over to Dan.

actually you know what? Tell eurocode to send their shit over to JHM too…didn’t they replace it with something? Maybe it was just clutch not flywheel. still can’t hurt for JHM to get their hands on one.

you get that awesome minor improvement in front:rear weight balance!

i just sent david a text asking for some pictures, when we pulled my motor, the trans came with it and was never separated. anyone have access to etka? maybe we can look up both part numbers and go about it that way? id die for another jhm clutch setup. possibly my favorite mod i did to the rs4

I still have the 4.2. I keep it when Im in keywest I use it for my DD. The 5.2 All I can say is this 11sec talk is weak. My car stock will do that. :stuck_out_tongue:

I laugh because the only documented RS4 Supercharger sucuess comes from the same blower thats on the S4. So by extension 3.0 of 4.2 that blower can only push so much air. When you stack it up the blower is going to tell the time more then the motor. The RS4 guys need a hero. The B6 guys have several. The S5 guys are getting laughed at with there PES fail.

Its great another B8 S4 went into the 11’s. Still I could care less unless there a member here. So go get that top spot time back Primetime.
