hand vs. machine...there is no comparison in the quality of the job when it is done properly on the correct machines. I'm not talking hand drill or dremel...I'm talking modifying the shaft in a milling machine, tapering the intake and output of the TB in a lathe and countersinking the TB plate in a drill press with the proper 100 deg. counter sink not a drill bit like some others have done. Also replacing the screws with 100 deg. flathead S/S screws and cutting them down flush with the back side of the TB shaft. Plus if you are spending 2-3 hours on each TB that is way too much time. Set up on the proper machines can be done easily in half that time with far superior quality work.
You can't produce this kind of results by hand on the TB housing...the shaft isn't as hard and can be done by hand if nessasary as long as the plate is countersunk on a drill rpess with a 100 deg. countersink. This SVT TB was smothed and opend up on a lathe...now it was an experiment and is over bored a LOT to repair a botched attempt by another member to create a 65mm TB out of a SVT TB...it is now a 67mm after the repair and machining (see the small circular area around the TB shaft). I have not finished the new shaft and TB plate yet but you can see the results of using a lathe to do the machining, this can not be matched by hand no matter how much time you spend.
I concur. I have examined one of Scott's optimized throttle bodies and there is absolutely no comparison between hand and machine optimization. Scott has told me he will be offering this service in the near future. Josh, no intent to hijack your thread or anything - I'm sure your TBs will be a good offer to CEGers.
