altitude, oh yeah Posted by Cmyles [Email] (#1126) [Profile/Gallery] (more from Cmyles) on Wed, 21 Aug 2013 12:20:53 In Reply to: Respectfully disagree. Compression is low., jjacob, Wed, 21 Aug 2013 09:52:48 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Axe-shelly those may be excellent compression numbers depending on where Alvin lives. Let's not scare him for no reason. An engine that has compression of 150 PSI at sea level will read 128 PSI at a mere 5500 feet (all else being equal). 5500 feet isn't anywhere near the "top of a mountain" in the western states where a lot of us live much higher than that. Additionally, plus, too, also the difference between 150 and 128 is more than "a few psi" man. (Now if he lives on the coast those numbers WOULD be a little low.) Aaaaaaand if his car is below sea level then all bets are off!
