Shaner S3 Rocks!!! Just installed the Shaner S3 that I bought from a member here. That tb is a work of 
art!!!! You CAN feel the difference up top and throttle response is a bit more crisp. Looks like it was CNC'd. If you don't have one yet it's the best money spent on a throttle body! It'll really help when I do the cam next month.

The only bad part about it was that Shaner didn't do the half shaft mod. I traded my stock one for the S3 plus $100. The seller was putting his car back to stock to sell. I didn't port the stock, but I previously did a clean job on the half shaft. When I got the S3 I swapped the shaft for the one I already did and THAT made it "perfect"

FIREHAWK#608, very nice explanation of the half-shaft mod!! it does wonders for part-throttle airflow.

I am sure he doesn't do the half-shaft mod because there are only marginal gains to be had, and it significantly reduces the structural integrity of the throttle shaft. I am glad it wasn't done.

Actually the half-shaft mod has been tested to over 16# of boost....w/o any issues. There aren't even any threads on the top part of the shaft...just the bottom 
Yes, in theory you may be lessening the integrity of the shaft a slight bit.....but for all intent and purpose I don't know anyone on this board that is running enough boost and is still using the stock tb for it to matter. The small theoretical loss is so minimal as to be neglible on most any LS1 motor out there. Are you going to be running 25# on an ls1 motor anytime soon? 30#? Me either....

HTS-2000, eh? i don't mind more time to complete, better results are what matter. i'd rather do 2-4 GREAT tb's a month than 4-6 good ones. where'd you find this stuff @?

Check out the video. They show you how to "mold" new aluminum from a steel cast. Pretty trick.

Cypher is right on the half shaft mod. Holley carbs have been this way for decades- the main thing is the remaining part of the shaft is behind the blade at rest which is the main reason its only "slightly" weaker. I have, along with to many to count other guys doin TBs, never seen any ill effects off of the mod other than extra power.

There are countless threads that raz on the BBK throttlebodies. The shaft probably broke because of faulty casting. I've yet to hear of a case where the stock shaft has broken because of the half shaft mod. Doing the half shaft isn't really considered "taking chances". Doing the mod might only show minimal gains, but it's one of those "every little bit counts" types of deal. Plus it looks so much better.
