changing water pump
I had to change the water pump and had all of this CRAP in the way.
2 pumps multiple hoses lines. large filter. the tubes on the exhaust make it a pain in the ass when changing plugs. And now my engine compartmnt looks like it has an engine in it.
I just plugged the end of the lines till I can get some headers.
But I removed 2 pumps all hose and filter.
I have been told at the dragstrip they can add up to 15 HP by removing the power steering belt . So I wonder how much these two old pumps were robbing me?
RE: changing water pump
The air pump isn't really using much hp at all, since there is virtually no resistance. I doubt you'd even see much of a difference with having the pump off. But hey every little bit does help.
