Some of the additional parts we used to make this unique little engine.
Supertec 906 cylinder cooling tin
Passion Rose intermediate gear.
906 225 cooling fan, combined with a Supertec Power Pulley and fan center.
The challenge with ducted cooling fans is that the closer the fan tips get the super-sonic the less effective it becomes do to harmonic inversion/cavitation . The 225 fan diameter reduces tip travel, the Power Pulley reduces the speed so that the fan actually move move air at higher engine speeds. It also reduces horse power losses.
Supertec idler arm updates (more important than pressure fed for reliability)
Updated chain box cover for pressure fed tensioners
Supertec rocker arms
We remove the old bushing and adjuster (if present)
Clean adjuster threads with 8x1.0 forming tap.
Ream the bushing hole
Black Oxide the rocker
Press in the new DP4 bushing and burnish
Surface the contact pad
Coat the contact pad with Moly dry film (TLML 2)
Treat the rocker to a Cryogenic conversion process
And of course a shout out to Aaron Burham's oil sump covers
