Stock Throttle Body Modifications

[illSHOyou]

This 65mm throttle body may have the same flow potential as the 69mm group buy units with stock shaft butterfly assembly. The upper butterfly shaft has been removed, and new screws installed. The mouth of the throttle body has been slightly camfered also.

we call that optimizing on contour.org. but you should do countersunk screws and shave the rear shaft in half. w/all that done a stock 60mm svt tb flowed the same cfms as a 63mm tb.

I didn't go that extreme. I figure its a improvment though. You have any pictures of the "shave the rear shaft in half?"

Don't you like those crimped screws? :laugh_ti:

I did a similar mod to my focus throttle body which has the same crimped screws and a ski jump throttle plate. The throttle response has more than doubled, the computer hates the mod and can't figure it out, but o well...

I really didn't want to shave the bottom shaft because I was worried about making the material too thin and accidently snaping the shaft during a sudden throttle shut.

The focus throttle body:

they've been done the way i'm doing them since i joined the boards back in 00,i've yet to hear of a shaft snapping,though if you went to thin i supp. it could. i've never had a problem getting the screws out the plate/shaft. but the ones in the damn tps!!! they use blue loctite on half of the screw,i almost always have to cut a slit in the head and use a flat head screwdriver to remove them.

I did this to my 94 ATX. Looks almost exactly like Warmonger's. Seems as though there is just a smidge of top end and it takes a little less peddle to get around. So a little low end. But, I also have ported intake, gasket matched surge tanks and gasket matched heads. So, with the BBB's I'm about to get, it should help with the cumulative affect.
