Agency power makes one since Evosport is out of business.

Does anyone have this on their C63? Is it worth getting? Currently I have MBH headers, X pipe, Resonator delete, Euro Intake, and Custom ECU tune. Was wondering if this crank pulley upgrade would give me a nice kick in power and let the engine rev quicker

Putting mine on monday. I have a feeling that this will be like when I installed my ROW air boxes. Thought my car was pulling better but it was mostly because i put clean filters in.

Eurocharged was making these very briefly. If you're not seeing them using it or Weistec, IMHO it's probably not worth it.

ive had the EC one for like 1-1.5 years, no issues... - CaptnCharisma ...i think ROW boxes gain 10-25 whp (some peoples results)

Try 0. My car made no more horse power and trapped the exact same mile an hour with row boxes. I felt a difference with the air box lids I modded, but it made the CEL come on.

So I had it thrown on Monday. Shop had to take out my radiator and use an impact wrench to get the bolt out for it so keep that in mind thats a possibility if you do it yourself.
So far I like it. Shifting feels faster and smoother since the car has thrown me off guard all week. No issues with the AC or electrical when at a stop or low rpms. No CEL. Personally it was worth the money despite needing to have a shop put it on. Just wasn't something I wanted to start working on to just find out I needed to pull out more stuff than expected.

That's like an extra little surprise!

thats odd..stock filters? or APE Dry?..i netted i think around 10whp with the ROW boxes before > after dyno ..my car actually chokes hard with the stock boxes
