A couple of friends and I took our cars to Addict Motorsports in Woodinville, WA today to see what our respective mods had yielded. We purposely chose Addict/Jason because he has a 4WD/linked Mustang dyno (the ego killer) and because I ran my RS7 Performance and E63S there in the past so we have earlier numbers to compare against. All the data below is based on WA 92 octane pump gas.

The C63S Coupe has upgraded turbos, Weistec cat'less downpipes and an Akrapovic exhaust (among others). It's a RWD car and it made so much power, we actually had a hard time with the tires slipping over the drums so 2 of us sat in the trunk (when I say "us", I mean them ) to solve that one to some extent at least. IIRC, it made ~580rwhp and ~680ft Ibs--not bad at all considering it was still slipping.

The E63S is actually my old car--not like my old car--my actual car so the mods my friend made since he took it over can be reasonably and objectively determined. Back then, it had nothing more than a EuroCharged ECU tune and made 621rwhp and 735 ft Ibs in dyno mode (note that dyno mode disables the front drivetrain becoming rear-wheel drive only). Today, the E63S has cat'less downpipes and an Akrapovic exhaust plus an ECU tune tweaked to take advantage of them. While the torque was roughly the same as before, it made much more horsepower, 674 all-wheel horsepower; note we decided to test it in AWD-drive mode because his tires weren't hooking up and to allow for an apples-comparison against the M5. That's a nice bump in power!!

My 2019 M5 Comp has BMC air filters and a JB4 piggyback tune; everything else powertrain-related is stock. Again, I don't have the WinPEP files yet so I'll update the post once I do. We ran it quite a few times, here are the MIND-BLOWING numbers that caused Jason (the tuner) to say, "I've never had a car make that much wheel horsepower", that includes R8s, RS7s, completely built motors, etc.

• Stock: 590 awhp / 570 ft Ibs --> that's comparable to others
• map 1 (+ 4 psi over stock): 640awhp / 680 ft Ibs (that's my best recollection; I'll update later)
• map 6 (flat boost @23psi): … are you ready for this because not one of us was?

… yes, you're reading that right. Over multiple runs (only two shown here) we progressed from 640awhp up through multiple map 6 runs yielding between 710 and 715awhp and between 730 and 740 ft Ibs of torque. Were these numbers isolated to this one car on this one day, I'd dismiss them as an anomaly but they're not--the M5's stock numbers are right on point; the E63S is also right where it should be and the C63S numbers seem about right albeit in need of a better/custom tune which Addict/Jason is working on. Add to that the fact that the M5 numbers climbed progressively from stock through lesser maps and ultimately to map 6 with consistent increases over multiple runs--call me a believer.

So far, this car has repeatedly run 10.7s in the 1/4 mile @131mph on undulating/uneven cold & totally crap farm road on pump gas. The weather is getting warmer here now so I'll take it to the dragstrip soon and get some numbers that truly reflect what it's capable of.

Do you have all connections attached(4vs2) on jb4 including obd2? These #’s on 92 octane? What would your estimate of chp be? Great #’s!!

Thanks!

Yes, you can't use anything beyond map 1 without OBD II (at least, my car goes nuts when I tried). The map 1 pull was good but substantially lower than map 6.

Yes, 92 octane.

Sorry, chp?

[Fuel-It!]

JB4 FTW! Nice results!

I think he means crank hp.

those are crazy numbers. what else is different between map 1 and 6?

Ah, yes... I'm an idiot. I lean toward conservative on drivetrain loss to avoid flame-wars and the like so if I use a 12% drivetrain loss, that results in 812.5hp but, to be candid, it seems too much to be believable to me but I don't know how else to interpret the numbers given the evidence supporting the credibility of them across 3 cars, multiple runs and stock numbers that align with everyone else's.

I'm not qualified to answer that fully. I can say that map 1 adds 4psi over ECU at its peak. Map 6 attempts to do whatever I tell it to at various RPM increments, in my case, I've set a 23psi target across all RPM increments--it hits that easily and climbs to 24 briefly as revs increase but the mean is ~23.

so to be clear, all these numbers are on pump fuel? i'm seeing dyno's for this car, which is cool but i'd like to see more of it in some roll racing to see what it's doing where it matters.

Yes, pump gas (92 octane).

I'm getting there on the compete-data but, as for roll-racing, it's just too risky on public roads and I know of no other legitimate local venues. I'm at the track (road course) in a few weeks to see how she stacks up in the twisties and I'll take her to PCR soon for some 1/4 mile times.

Damn I wasn't planing to tune my f90 but I guess I have to now. So what would it do with DPs? Another 50 or so?

That's where I was headed with my mods. I'm doing DP's first. intake after that and tune last.

Great question. I don't want to just guess at a number but I imagine a custom ECU tune with DPs, etc. would provide noticeable gains.

[Who's on first]

Do we need to do anything special to run the cars on a dyno?

I have one scheduled for the 21st.

(It's an AWD Mustang Type dyno)

I tried my car on a Dynojet non-linked--> it was a nightmare. I tried it on a Dynopak(?) hub dyno--> it was a nightmare.

We shoved it on a Mustang linked-dyno and floored it--> et voila!

The car does have a dyno mode but we didn't use it. That was based in part on the advice of Imran from Evolve.

OP, did you do the ewg connections as well as TMAP? Am surprised that with that much boost and 92 octane it wasn’t pulling timing?? Certainly impressive numbers. Do you know if your Mustang was calibrated to read Dynojet like numbers? Thx

Yes, sorry, my previous answer was incomplete: yes, TMAP, EWG and OBD II are all hooked up.

I pulled two map 1 runs, a map 2 run and 2 map 6 runs (@23psi) using the JB4 mobile app--I sent the map 6 runs to Terry. He replied 4 or 5 mins later saying all looks fine.

If Addict's/Jason's Mustang is calibrated to feed egos, I'll eat my shorts. He's not your conventional businessman--pretty much does and says what he wants but he's great at what he does and I love the guy! Short story: I don't know but I find it highly unlikely. I'll ask him (whether he responds or not is a different matter).

Is map 1 +4psi? And that is approximately 22psi (?)

Map 1 is +4 psi relative to ECU.

I don't think map 1 reached 22psi. From memory, I'd say it peaked around 20.

Logs of Map1 and Map 6 from the dyne would be interesting to see..

I'm not sure what happened but I can't find the map 1 log. I do have two of the map 6 logs which are arguably the important ones although, granted, it would've been nice to contrast against a map 1 pull.

PM your email address and I'll send over the CSV.

Thanks, but the comparison had my interest. Very strong power production though. Should run hard !
