Well it absolutely works.
Fire it up and the engine smooths out as the exhaust manifold warms up, which happens very quickly, in about 20 seconds.
Put power on the solenoid and it opens to cold air.
Our sharp eyed readers might have noticed I did not use the Russian thermostatic air mixing valve. I needed a 2.5'' to 1.75'' reducer elbow to do a clean install, so I ordered one from frozenboost dot com.
I need that hot air on startup more than anything at the moment.
Cold air open.
Hot air flap closed.
Preheater tube attached to manifold
Vacuum solenoid.
Extra vacuum solenoid next to 15mm wrench.
Actual size.
