We put together this performance package for the M8 engines and it has an unbelievable power for just a bolt in cam. It uses stock HD springs and makes a very reliable combo producing over 30 RWHP from stock! First we start with a 475 Chain Drive Cam then we add new S&S Precision Roller Lifters, Quick Install Pushrods Set with your choice of chrome or black tubes and all necessary gaskets. We strongly recommend adding a Billet Cam Plate and Oil Pump for any combo over 110RWHP which is very realistic with this setup but we do offer it both ways. On the bike we have our dyno results from it has a TTS Mastertune, Hi-Flow Air Cleaner and 2-1 Pipe with no other mods and it made 113 RWHP and 120 Ft lbs. of torque. Which is a crazy gain for such a minimal cost. We offer a TTS and installation with Dyno for our local customers.
With some more dyno time we have added a few more cams to this kit. These packages are without upgraded Oil Pump & Cam Plate. We have a separate page with those kits.
