Decided to go today to Dyno my car. It's on a dynojet. Temps were 69 outside at 69% humidity. My start IAT's were mid 50's to low 60's. Must say I was shocked how quickly the IAT's would drop after he let off, within a few seconds I was back in the low 60's and then about a minute later mid 50's. First Run we did, something went wrong on his end and we got no readings, so all I have is 2nd and 3rd runs. The 3rd run he had trouble getting an accurate read on the torque numbers. Both runs are done in 4th gear. Mods are in the Sig but if you got a phone and cant see it here it is.

Eurocharged Mids
Primary Cat Delete
Muffler Delete
Needswings Dual Intake
76MM Pulley
Killer Chiller
2.5 Underhood Tank
EC ECU/TCU Tune


One thing to mention i ran back to back pretty much only 2 minutes tops between runs, there is no ice in the tank. I wanted this set up to be tested wasn't looking for a one time glory number.

480 RWHP and 556 RWTQ
481 RWHP and 536 RWTQ

Nice! That Killer Chiller seems to be working great

karpetcm

Ya the recovery is really amazing.

Looks great boss you should be very happy with those numbers for sure.

Wonder what it would make if you removed the filters from the tubes?

That's aweome, great numbers and consistency. Must be a blast to drive.

karpetcm

Yes for sure, thank you. Lots of torque from that 76mm and pulls really well top end now. Appreciate all your advice and help, to everyone.

FunkTron

and you are on the stock injectors?

karpetcm

Yes on stock

VictoryRoadPerformance

those numbers are really good. I would consider upgrading injectors next, More for the fear of them failing then out of necessity.

With that cooling and the headers you could also drop to 72mm without an issue.

karpetcm

Would 550cc be okay

VictoryRoadPerformance

yes, 550cc would be enough

Before jumping onto injectors. Log your AFR on highway pulls and then see if you are running lean.
Dyno with hood open and fan blowing is will equate to different AFR numbers.

Great get up today turn the car on and got an exhaust leak. Car sounds like crap. Gotta see were thats coming from did a recent headers instal

VictoryRoadPerformance

The replacement would be to hedge against an injector failing, vs smoothing AFRs, The 550cc would give you some head room for future mods aswell.

Bosch 550 are more likely to have issues due to low cost pig tail harness provided by some vendors than a stock injector failing.

E55amg0220

I soldered in good pigtails and removed the stock injector plugs for my 550cc injectors they wk amazing.

VictoryRoadPerformance

Yeah, never had to replace a connector for anyone so I guess just be careful where you buy them?

Fountain35

Do you install LT headers?

MSG 55G

Bought a set of Bosch 550cc from VRP and installed back in November, NO issue here!

karpetcm

Its just figuring out if i do 550cc injectors should i go with 72mm clutched pulley or not, or should i drive it like it is and wait another 1 or so and get a 14 E63. I fixed my exhaust leak as well today. Down pipe that connects to the headers bolts had come off one on each side and the other 2 were loose.

MSG 55G

Glad it was an easy fix! Let me guess, Serge did your headers install! lol...
