131ci Stage IV Lowrider S / Build / Dyno / Stage 4 Harley / Milwaukee 8 / Series / Before & After

In this video series I will be building the 'bolt on' 131ci Screamin Eagle stage 4 kit. Once the build is complete & I'm happy with the dyno results I will be making a camshaft swap to the Cyclerama 512 that has been specifically designed for the SE 131ci Engine.

This video is part 1, I take you through a complete time lapse of the engine assembly/build process then, fit up the D&D Fatcat 2-1 exhaust system & get it on the dyno.

I talk through some of the differences between a drop in base map & then a tune that I have done to suit the bike. Trimming the fuel & VE Tables makes a huge difference to the HP & TQ curves as you will get to see first hand.

I was actually surprised at how much power the bike made on the drop in tune, but obviously I wasn't going to leave it that LEAN!!!!

Harley-Davidson & Screamin Eagle have come out swinging with this engine combo!!! The power & torque available is amazing.

I can't wait for to get the Cyclerama 512 Camshaft into this monster because I know for sure we'll be making MORE POWER!!!! Wes Brown really knows his Cams & I for one will vouch for just how SOLID & BROAD the torque curves are from his cam grinds, not mention the power curves that just keep going UP TO THE MOON!

Stay tuned for Part 2 of this build when the cam goes in.
