Justin, i run the one on one intermediate, it is pretty much a copy of the berg inter mount.
Colin, the traction bar helps prevent the engine from moving downwards but not rotationaly, the inter mount keeps the nosecone from moving around too much, i have broken nosecones before in my old 1914cc 64 on the street so i know how that feels!!!!
The torque bars work differently, they tie into the framehorns, the idea is to prevent bent framehorns on hard launching cars that produce a lot of horsepower and torque. ive managed up to now without one so if your car is light enough and running anywhere near the 12's i would say there is no real need for a torque bar, built box and slicks may change that scenario as with that combination you can launch the car putting far more stress on pretty much everything, check out Daves car, he has torque bars tied into the frame horns and cage, all adjustable and all handmade.
