are the exhaust valves the limiting factor in the vw i ask this after reading bob hoovers accounts on the subject and he is adament that the exhaust valves get to hot when in continuous use at high rpm .i hear 2900 -3000 or around 55-60hp continuous being the maximum
so question is if they are getting to hot will fitting larger valves help by transfering the heat over a larger valve seat area and into the head. this could be a good move potentialy pureely for the cooling aspect has anyone fitted larger valves in the 1835 than standard of 35in 32 ex and what did you find . in the 2180 i am fairly sure bigger valves are needed phil ------=_NextPart_000_027F_01C6590B.250B55D0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=iso-8859-1"> <META content="MSHTML 6.00.2800.1106" name=GENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=#ffffff> <DIV><FONT face=Arial size=2><FONT size=1> <P>ar<FONT size=2>e the exhaust valves the limiting factor in the vw i ask this after reading bob hoovers accounts on the subject and he is adament that the exhaust valves get to hot when in continuous use at high rpm .i hear 2900 -3000 or around 55-60hp continuous being the maximum </FONT></P> <P><FONT size=2>so question is if they are getting to hot will fitting larger valves help by transfering the heat over a larger valve seat area and into the head. this could be a good move potentialy pureely for the cooling aspect </FONT></P> <P><FONT size=2>has anyone fitted larger valves in the 1835 than standard of 35in 32 ex and what did you find .</FONT></P> <P><FONT size=2>in the 2180 i am fairly sure bigger valves are needed</FONT></P> <P><FONT size=2>phil </FONT></P> <P> </P> <P><FONT size=2></FONT> </P></FONT></FONT></DIV></BODY></HTML> ------=_NextPart_000_027F_01C6590B.250B55D0-- -------------- next part -------------- No virus found in this outgoing message.
