I know Fiid was doing one of these, anyone else in progress or complete?
After doing the contortionist trick of adjusting valves with the exhausts in place a couple of times, I'm in the middle of pulling the HEs off my 1.7 to replace a pair of exhaust studs, and reminding myself how much easier the job would be if the exhausts were off, but thanks to the stock heater system how big a hassle that is. I hate exhaust studs pulling out (No. 3 cylinder, as usual). And all this trouble for only 80hp. 140hp or so from a water-cooled engine with hydraulic lifters (or 20K mile valve adjustment intervals) is starting to sound pretty good right now. If it were any easier to run water lines, I'd be all over this already. |

The torque will only be there if the bar or the mounts are sufficient flexible to allow it. I'd not use the rubber mounts on the engine to the bar, but solidly mount the bar to the engine. Use rubber mounts at the body end. Esp. if you use the threaded bosses as the base of the cylinders as extra stiffeners, what you'll end up with is simply a solid cradle from the stock mounts to the front of the engine. This should flex very little, and exert very little torque on the front of the bar. This can be made with angle, mounting the vertical part against the pan, which would stay well out of the way of exhausts and shift rods. Any flex found could be solved by just making the vertical bit of the angle deeper.
I note that the ends of the stock bar in the stock 914 setup are subject to about the same amount of torque as this proposed mount would be, just turned 90 degrees. The stock mount has mounts on the end, and a narrow mounting point in the middle, with all of the mass of the engine bending the bar through a pretty significant length. The stock bar(s) are stout enough to keep this bending to a small enough degree that there's essentially no torque on the mounts at the ends. |
