My home brew OBA set up sparked a lot of interest, so my newest creation, might do the same. With the OBA I needed a way to bump up the RPMs to about 1500-1800 for the best performance. I was using a "calibrated" zip tie between the throttle body stop, but I wanted a way to work three pedals at the same time also. I have seen a lot of write ups on this, but they all use a 10 speed shifter, or a BMX Brake lever. I like to be a little more creative then that. I found a hand throttle for a ridding lawn mower at advance auto for $8 and then picked up a 4 pack of bike cables from Wal-Mart for $5. The key to making the hand throttle work in harmony with the pedal is the 16lb chain from Home Depot for .54 cents. I mounted the hand throttle on the front right hand side of the drivers seat, routed the cable under the carpet, through an existing hole in the fire wall and then up and similar to the accelerator cable. I found an air line connection ( bolt with a hole through the middle) to attach the cable housing to the accelerator cable bracket. The end of the cable attaches to about 3" of the chain and the chain attaches to the throttle body right next to the accelerator cable.
It works awesome and looks very clean. It has a groove in the handle throttle that clicks it into the stop position for a little bit of safety. I wanted to take some pictures during the install, but Jess had the camera and she wasn't home. I'll try to get some on Saturday during the post ride air up.
