And now a higher resolution photo of the Faux Cam motor on the dyno.

The motor uses the Wilhoit 2133 kit which has about 160 hp in single plug form. Gregory’s motor is twin plug so it will be interesting to see if there are any Hp gains due to the second plug.

More to come. Thanks for following along.

Well, it has been a while since I last posted - I have been busy getting the new home in Seattle ready to live in and getting ready to retire.

Gregory has his faux cam motor running in his 904 clone and those of you at Monterey last week and this week may see him driving the car around town. He says it is race car fast, and he should know. The car was built by Martin and Walker in the UK, where I also have one on order. Gregory's motor is a 2133cc build using Wilhoit's heads and crank etc with the prototype of our pushrod distributor V drive. Zero problems with the distributor V drive so far. My 904 project will use the 4 cam motor currently in the 59A, and the 59A will get my faux cam motor when the time comes.

I have been making updates to the distributor V drive CAD model to incorporate things Gregory and I learned from the prototype. We reduced the diameter of the mount bowl for Faux Cam motor use down to the same size as the normal 4 cam V drive, made the outer end cap part of the drive body, since the "guts" can be loaded from the motor side and made many changes that reduced the front to rear length of the mount bowl and V drive body by about 1.5 cm. If Gregory's measurements are right, this will allow the unit to fit on a pushrod motor with the stock rear engine tin in place. We plan to do a 3D plastic print to make final checks before we make another metal unit. Once everything is confirmed I will also make a second version of the mount bowl for use on pushrod motors still running the stock crank pulley and fan shroud. This version will have a larger diameter bowl to accommodate the stock pulley, which will make it viable for use on twin plug motors where the owner does not want to go the full faux cam route.

File comment: V Drive body with mount bowl (in red). larger mount bosses for drive body to bowl to allow for larger washers inside the bowl used to mount the body to the bowl. Cut out on the bottom of the mount bowl is to clear the dry sump oil pump.

File comment: Also rotated the distributor clamp bosses from the prototype to make the height lower. This then required moving the oil inlet boss on the right side down so the oil line would clear. Probably 30 other little changes.

I had planned on taking the 59A with 2 liter 4 cam motor down to Rennsport VI, but found an exhaust stud pulled from the head when I was in Seattle earlier this month. So I pulled the motor, crated it and it is on the way to Jacques LeFriant for a refresh. This was planned anyway, just not so soon. The motor has about 40 vintage race hours on it from use in Stan Gold's 904 and RS60 before I purchased it, so it is time. I plan to assist with the tear down the week after Rennsport.

File comment: Crate packed. Used Adam Wright's method with ratcheting tie down straps to hold the motor in place. Bottom of case also blocked in place. Any other bits held down with metal strapping screwed in place.

I hope to see as many friends as I can while at Rennsport in a few weeks. Or stop by Jacques shop the week after to see a torn apart motor.
