Throttle Body Spacer/Coolant Flow

I had an engine with a throttle body spacer on it that I picked up for spare parts. The idea of putting a piece of plastic between two pieces of aluminum to stop heat soak in theory does seem like a decent idea. Well I know that throttle body spacers block off the coolant passageway and can cause problems. Has anyone ever thought to machine a new passage? I mean it seems like you could do it right on the inlet if I'm not mistaken.

Any thoughts on this? Otherwise I geuss I have no use for that TB spacer haha.
 


why would you do that? why would you want the throttle body hot? you want it cold block that shyt off "hence" cold air intake =better performance and more hp:th_thumbsup-wink:

lolwut?

There's several threads regarding this already. Coolant flow into the throttle body was apparently done to keep frost off the buttefly/tb blade I believe. Blocking the coolant shouldn't hurt anything. I'm not sure how many people block all coolant going into the blower to be honest.

well thats what ive always been told by the older guys that race cars especially lt1/ls1 cars, less heat at throtle body the more cold air get into the motor :th_nanana:
 
these blower cars dont need cold air..they need MORE air.

TW, drill and tap the LIM instead of plugging the blower. there are two holes that youll need to cover. however, once you do this youll also have to pop off the end cap on the drivers side of the LIM and open that up a little more too so that the coolant flow to the rear head isnt compromised. part of the flow to the rear head is what normally flows through the throttle body and blower.

then once you stop coolant from going to the throttle body youll never need a new throttle body gasket ever again.
 


if you have wrapped headers/manifolds with cooler t stat and fan turn on points, the tb shouldnt get hot. I even took my TB heatshield off and the TB doesnt get hot. its much cooler using that tb spacer
