Badass

 

WoW

I didn't think it had throttle plates at first because of the way you have built them. They look very clean and simple. Excellent work!

 

thanks guys! yeah i got 2 springs tucked away in there too on each side of the throttle arm.

 

wow great work

 

damn nice work - ask TWM for a job and then make roller style openings for the next batch

 

That is some awesome fabrication right there

 

Did you make the butterfly plate too or did you buy them? I just thought it would be difficult to size it exactly right. Also where did you get the air tight bearings?

That's some tight work

 

the blades are very easy to make. im running about a .001 per side clearance and im using bronze bushings instead of bearings. yeah they will leak a little but not enough to matter. i should be able to close it up tight enough to kill the motor if i wanted to.

when i build single tb's i do use bearings and then a seal similiar to an oil seal on the outside of the bearing. the tps end is still a bushing but the tps sensor itself uses a gasket so that traps the remaing air.

since this manifold doesnt use idle air control the butterflies will have to be cracked open a bit just to get it to idle so any air that would leak through the bushing isnt gonna hurt anything.
