The cylinder head is the same as on the 9000 wich means the head has the mounting holes there already. The question to solve is how to mount it to the chassis. To make it as firm as possible...rcmdesign said:Where does the mount attach to the motor? Is there already a pre-drilled spot or do you have to make the holes?
Agreed. Once you get under the car to instal a nice new Poly version it's pretty obvious where the failings of the stock one are. Now I just need a new rear mount.genuinesaab said:We explored that option when developing a mount upgrade for my Viggen, and later offering it to our customers. You will notice that most of the 9000 people still have to upgrade the trans mount and the 9-3/900 is even softer than those. The main problem is that the gearbox (actually the end where the shift rod enters the gearbox) can move longitudinally away from the lever in the factory soft rubber mount. Tying the belt end of the engine down helps the rocking of the powertrain but does little for shifter precision since the gearbox is still free to move away from the lever. But you are free to do whatever you want. Just sharing what I have learned.
Yeah, it took me 15 minutes ... in pouring rain. It's easy. When I combined that with a fresh set of plugs (at least in my case) I couldn't put my keys away! I've been having too much fun.genuinesaab said:We have been able to tune out all but just a little of the vibration, it is not a problem. The stock right mount is not a problem either. We are only changing the left mount (the trans side) A new stock mount is $100 so the price difference for a mount that will last the lifetime of the car vs the stock rubber that will fail a few times is a pretty good value to me. It is also a simple 20 min job with no cutting or other silly stuff.
