2017 C63s Edition 1 JB4
SuperFlow Dyno using Eddy-Current method, where the Dyno wheel is loaded so you get a more true street number. We strapped it down, measured the tire diameter and put in 4K lbs for the weight of the car. Then put car in "Roller Test" mode, and all pulls were made in 5th gear. Note it was about 105F outside but not sure exactly what it was inside the shop with coolers running and 3 fans in front of the car. Cooled the car down to 120 IAT's for all runs except the Valet Mode MAP8. Fuel was Shell 91Oct


Here is the HP/TQ for the runs:
Stock in C mode = 335/410 - seems low
Stock in Race = 330/436
High Flow Air Filters Race Mode = 335/364 - not sure how I lost TQ
Map1 Race Mode = 419/453
Map 8 Valet in Race Mode=285/391
Map 7 +5psi =436/? (getting the graph again since it did not print)
Map 7 +6si = 438/523

Logs attached and will scan in the Dyno graphs later

Thanks. Itís a shame that more often than not, something looks whacky at a dyno. Youíre right that both stock having 335 hp is low and that the 364 tq with the air filters is really weird and highly suspect.

anything more on the codes/rough running today?

thanks again for doing the testing. Looks like you skipped doing map 2, correct?

Delta sounds good for a load dyno. Remember numbers will vary dramatically based on the machine and operating parameters. Only the dynojet brand is relatively consistent. I see you emailed the logs in, we'll check those out tomorrow for you.

Yeah looking at the Delta I think things lined up, my plan will be to find a shop with a Dyno jet in the fall when things cool off, Iíve only ever used DJís so this load dyno as a new game. On the street the thing is insane, I added 3 gal of E85 and topped off with 91 and holy s**t itís spinning the 305ís even with the 1st and 2nd boost reduction 😎 but itís totally controllable

Are you using WMI with 3 gal of E85 on Map 7? What Map are you running? I got rear ended last Tuesday right after putting in E30 (4 Gal of E85 with 93 octane top off), so my car is unfortunately at the shop for another month. I had a difficult time finding a shop with a Dynojet in my area. Most use Mustang. I was planing on Dyno-ing. I want to invest in WMI, but I am not sure if I should take the leap yet. Did you observe any codes or issues with the WMI install? Thanks!

I did try using E85 with all MAP's including 7, but my car did NOT like the E85 even at 3 Gallons with 91 top off. I was getting all kinds of misfire and vac leak codes and limp mode, so I ran that tank out on the freeway. Then I filled up with 100oct race fuel and most all my issues went away. Now I am about maxed out on the fuel trims on MAP6 /100oct so will probably stick with my WMI using 91oct fuel on MAP7 with Boost Add or 5 or 6 and try 7 at some point.

The Install of the WMI is time consuming but if you take your time it can be installed very stealth and even keep the OEM cabin air filter box.

I still have not found a shop that will allow me to "rent" their Dyno-Jet most won't allow that unless they are tuning you or doing other work.

Sorry to hear about your accident, that must be very frustrating! Let me know how you do on the E85, 4 gallons is kind of a lot, most go with 3 but my car did not care for it!

Thanks for the prompt feedback. Yeah, 4 gals of E85 is right at E35 topped off with 93 octane. I did not get a chance to fully test the car on the mixture. The additional 2 octane might make a difference on how the car responds. We'll see.

Soon!! Production always takes a little longer than we'd like on these things.
