At Wayside Performance, we are always pushing the boundaries of what is possible on the Ecoboost platform. 

With our extensive knowledge and experience of high power engine builds, we have developed a keyway kit for the 1.6 Ecoboost to prevent the crank pulley slipping and causing catastrophic engine failure on high performance applications.  

The standard crankshaft on the 1.6 Ecoboost relies solely on the torque of the crank pulley bolt to retain your engines timing and preventing piston to valve contact. When raising the RPM and overall power levels, the OEM spec Crankshaft has a big risk of slipping and causing huge internal failure. 

Please see our YouTube video here to see 

This is the same kit as is on our own ST180 G25-660 race car. 

This service is to cut the keyway in your existing crank. You will need to send your crank and crank pulley to us and we will return it to you in 2-4 weeks. 


Had a Turbosmart 50/50 dual port blow off valve fitted by Wayside Performance today on my Focus ST Mk3. Great noise. Fantastic service and Chris knows his stuff. Supplied and fitted in under an hour. Definitely recommend.

Hands down the best garage I’ve ever been to. With some expert advise from Chris I was able to get performance out of my car that I could only have dreamt of before

Traveled down from Bolton today for injectors and remap on my Corsa VXR Nurburgring. Chris did a great job really happy. Great drive home I would highly recommend.
