Engine Performance problem
1990 Toyota Corolla 4 cyl Front Wheel Drive Manual 80,000 miles
Why is back pressure being said to be important to have in a naturally aspirated engine? And why is it important to have none in a boosted one?
Isn't it right that if the exhaust gases goes out of the engine faster, then it will decrease wasted power, and improve performance of the engine?
Then what is back pressure for?
have the same problem?
