Tb coolant loop ?

Hi i heard that you can take the coolant out of the throttle body and loop it gas anyone got any threads on it or picture or something I know there's a search bar but it comes up with irrelevant posts and can't find a suitable post

Search Pollyp's blog he's done it and should have pictures

Take off the two coolant pipes from the TB and joint them with a small piece of pipe

Coolant through the TB and MAF sensor originally served to them both at a stable warm temp (during freezing conditions) and also operate the primative waxstat fast idle mechanism (which nowadays tends to seize open).

I bypass/eliminated the TB coolant lines to prevent the hot coolant from heating up TB. Cooler intake components = cooler air = denser air molecules & bigger heat difference between cold air vs hot combustion = more combustion pressure = power

After disconnecting the TB coolant, the coolant operated fast idle waxstat will no longer work (although they tend to age & seize anyway) so the sprung waxstat mechanism that keeps the butterfly open will need to be removed.
the electronic IACV at the front does the same fast idle job. prob a good idea to clean and calibrate the valve making sure it works perfectly.
