Its were you take half of the shaft off the throttle body shaft where the plate goes.

I personally don't like how he did that. I would think you want to keep the throttle plate in the same spot on shaft and grind off the bottom, this way the plate is still in the center of tb. Just my opinion, I went the easy way and bought a 60mm.

you cant grind off the bottom, its where the 2 screws attach the throttle plate to the shaft. That and judging by your current mods a 60mm tb is way to big. the half shaft on a 52mm atx tb will net about the same flow as a 55mm tb with a full shaft. Its an easy free mod. Casue lets face it $200 for a tb, no way.
Yeah 60 is a little big my manifold opening is only 55, but when I see a good deal I impulse buy. $125 new still in the box. I will get more use out of it one of these days when I get the turbo installed. Later that night I realized I was wrong about what I said about it being off center. The plate only moved down, not to the side. It would only be off center when open and then it wouldn't matter. So my mistake, sorry for being human.

Its all good, im not arguing with ya, thats not me. But not to rub it in, but your wrong again. The plate doesn't move down, it stays in the same location. On a stock TB the plate actually goes in the middle of the shaft via a slot cut into it. all your doing is removing the top half of the shaft, then reattaching it and then screwing it back in and cut the screws down.
But hey a 60mm for 125, i would have passed it up either

Damn, I must have not paid much attention to the stocker I had at all. I had it disassembled to do this and found the 60 and never finished it. It's in the bottom of my toolbox at work, I have been meaning to check it out since we got on this subject and never think about it when I am at work.

See the Neon guys round here make fun of me for half shafting my 52mm ATX TB... lolwickedgoodneon wrote:you cant grind off the bottom, its where the 2 screws attach the throttle plate to the shaft.

has the 52mm half shafted been tested for CFM flow..? anybody know?

id assume WOT would be about the only time the size of the TB rly comes into play neway. Idk, id just like to see what they flow vs. a untouched ATX.. which would mean testing them at WOT.wickedgoodneon wrote:not to my knowledge. from what i understand its more of a WOT mod. Meaning there are not real gains unless the TB is pinned wide open
