V8 air conditioning compressor instalation help
Posted by: rvrana

I have a 1979 MGB with a Rover P6 motor. My wife has asked me to install A/C on the car if we are going to make any long drives in the future, IE - MG 2018. I have the original 4 cyl A/C kit from the car but need to mount a pulley, compressor, and condenser on the V8 motor. I was talking to D&D about their compressor bracket and changing out my rover harmonic balancer to their Buick 215 model (even sent them the balancer). They sent the balancer back with a note "parts no longer available" and do not answer calls or email so I need to go another route. Does anybody have any suggestions on a compressor mount and compressor for my Rover motor. I think I can get a pulley made to fit the harmonic balancer once I have the compressor set up installed.

If anybody has suggestions/pictures on how to mount the condenser that would be great.

Please contact me off line so as not to clog up the forum

Hi Ralph and welcome to BritishV8! There are a lot LOT of guys here who have AC on their V8 MGBs. You should go through the gallery and see how they have done it. Just go the the gallery and select MGB and look for the Buick or Rover engines. Like this: []

I made custom brackets for mine so can't help that much, but check with Rick (Mowog1), I'm pretty sure he sourced a bracket somewhere that uses a Sanden compressor and V-belt. Use the biggest condenser you can mount.

Hi Ralph, it's great to know you're still involved with the MGV8 hobby. We haven't heard from you in a while. I'm the fellow that purchased a Webaso Roof from you back in Cleveland around 20 years ago. I was trying to decide weather to install air conditioning at that time and you mentioned you had a roof panel with the "fold back" roof and brought it the next day. I bought it and threw it in the back seat of my Bonneville and the rest is history. The car was completed and now is owned by Allan Moor in Tipp City, Ohio.

I sourced my compressor bracket through D&D in Michigan.
