Well he could potentially get the tune and exhaust…but I doubt it.
Last I heard the exhaust is still another month from full production. The tune is possible, but not an easy process to get one if you aren’t near someone with the necessary cables and such.
I have one of those cables ;D…bought it to install the tune on the S6
Thanks!! I will be back to the track in a month or so to test out the new parts. I am really fighting to not have exhaust but it seems I will end getting some. We will see…
well, the RS4 downpipes are 2.5" and have 2 cats in each pipe. You should pull the downpipes and eliminate the pre-cat up by the connection to the stock headers.
The stock 2.5" downpipes then neck down to 2.35" just before the stock catback, which is also 2.35". You’re giving up a bunch of flow from that neckdown back…but if you want to keep it, just keep it. But make sure you knock out those pre-cats. If you don’t get tuned, you will need to add spacers to prevent a catalyst efficiency CEL. If you do get tuned, it should prevent the catalyst efficiency CEL from happening.
Well, since they had to switch to a new fabshhop, they also needed new jigs because the ones the original fabricator were not really…good. He was good, but it was like messy handwriting as an analogy…only he really could make them work. So they had to basically start from scratch, then test a couple of fabshops to see if they could handle the work, and do well. They’re moving forward now. Bit of a backlog though.
As for the tune, there’s no way anybody can get JHM tuned for an RS4 right now. Not even Dan @ JHM. Their server deal they had with VAST turned into a negotiating point/hostage that VAST used in the dispute over the clutches for the B5 S4…and since VAST has gone flat mental, it doesn’t look like that’s coming back anytime soon. So they need to get on another server, with safety, protection, distribution. We’ll see what happens. It’s taking ages for a good reason…JHM doesn’t want to just let anyone see their tunes. They need to be very safe about it.
So what’s the actual ETA for the 2.75 S4 exhaust? Because I think that I would want that instead of the 2.5 FI exhaust.
JHM doesnt make a 2.75" exhaust for the S4. It’s for the RS4. The 2.5" FI exhaust is for the S4.
Thanks karsty, I just got off the phone with them. After they make the RS4 2.75 they plan to make one for blown S4’s as well. But that all seems pretty far off. Looks like I will be settling for the 2.5 FI, which isn’t too bad either. ;D
Sakimano, I will be running a Jhm tune. I had a good long talk with Dan , give him my opinion on a few items as well as taking some of his opinions. I did explain I will break this car in the process of being competitive, but I don’t mind about that. I did tell him point blank his time will be in jeopardy, he embraces competition. That Shows that he is a good guy.
lol you sound just like Dan funny enough (breaking records and parts).

his RS4 time was 12.29 @ 111…so he’s second. 2000S4 (george) ran 12.28 @ 112.45. That’s the ‘all motor’ benchmark.
Since you’re a good driver, you should be able to squeeze quite a bit out of the car, but I have to say, Dan and George are excellent drivers. They have all of your mods + 2.75" catless full back. You’ll be hard pressed to have your driving make up for that 20 or so whp you’ll be down.
My plan is:
LW rotors
LW flywheel + JHM III clutch (when my clutch goes)
Intake Spacers
Piggies
Stock catback
JHM 93+ tune
My goal is 12.4 @ 111 (which would be 0.5secs/4mph faster than my stock 12.9 @ 107)
saki, this forum is very lucky to have you as you contribute a lot of positive and correct informatin.
as for me putting a hurtin’ on those guys we will see in due time as I not giving away all my little secrets just yet 
you will have well rounded car when you install those parts!
I did put my car on the rollers today , since i am puting in my clutch/fw and few vgarious other bits. I wanted a base-line before its modded. it put down 357@ 7900 rpm iirc , this is on a mustang dyno. what is about the average output for a stock rs on a mustang?
357 whp?
that’s really high frankly. Usually guys see about 290-310 on a mustang…maybe 320 if freshly carbon cleaned…330-340 if tuned/exhaust (other than JHM) and up in the 350-370 range if JHM tuned/JHM full exhaust. Of courrse ‘usually’ is a tough term to apply since so few modified cars have hit the dyno.
I guess all that matters is a baseline and a delta once you go back to the dyno. Just make sure they use the exact same calibration as they did today. Fact is though, the most effective ‘dyno’ was done a few weeks ago (12.84@107.9)! I’m sure your delta at the strip will be far more important. Try to get back out there before it gets too hot. I hear you guys had 30 degree weather a few nights ago. Would have been great DA.
I agree to the dyno results, so we did it again . This time 355 was the result. I was quite surprised as this dyno netted 235 HP on my stock 370z , after all mods done to my old z , it put down 319@7900.point being was it is not a “high reading” dyno. Yes mustangs, can be manipulated, I have nothing to gain by this. I will aquire the graph and post it. Yes, we had great weather I bit ago, but I have a shitty clutch.
yeah, no doubt about the dyno. That’s just awesome numbers for an RS4. Looking forward to seeing the progress you make with your car.
Pretty amazing that, all motor, you were able to go from 235 to 319 whp on the Z. That’s nuts.
What was your best stock quarter mile vs. your best modded quarter mile on that car?
I should as I did with the Z. As for my times with the z, stock iirc 12.9’s fully modded 12.24@113 w/ 1.83 60ft street tires and original 19’s.
I am trying to post my dyno graph and video. Brb
Also… I made 354hp/267tq
Definitely significant, it is nice to see another company other than JHM getting some positive results for the 4.2 platform
Top of the league - well done to MRC/TTS I hope they follow this thread.
p.s. horsepower/deltav…who the hell makes your videos…Guy Ritchie? they’re amazing
I’ve never seen this one before.
