About cold starts killing cars.
My first house was on a very steep street. One of my neighbours had a new Nissan something that he used to just fire up and shoot off up the hill, no warm up.
Engine was f**ked in a year. I kid you not.
The rest of us had mechanical sympathy, our cars and bikes...
1st start of the day in cold temps, I'll idle it until some heat is showing on the gauge. Otherwise I'll just let the fast idle reduce and go.
I'll never cane any engine until it's showing normal driving temps
As i understand it, you can't replicate on a dyno the intake airflow in actual driving.
So any differences shown on a dyno run may not occur in the real world.
