AX,
another of your awesome ideas. When they start scraping those EGR heat exchangers, send us a few, OK.

(erased the thermostat issue) Modern cars with electric fans are designed to warm up in 2 miles unless very cold air temps. with grill block even faster.

I have everything made to block the exhaust on my F250, i just haven't had a chance to test it yet. This vehicle had a clutch fan which is terrible for warmup.

What data do you want?
temps., outside air, engine coolant vs. time
manifold vacuum(to test the Exhaust Gas Retention)EGR
Back pressure?
