R4 a/c compressor or sandem compressor

[chvz99]

hey guys, im trying to get my a/c working before it gets real hot here in tx,
what would be a better choice for an a/c compressor i have no experience with any of this 2,
some say r4 is a POS, too noisy and unneficient. but this would be a bolt on deal on 88 to 99 ls swaps, since one can use factory a/c lines and the new holley bracket looks like a factory piece. some say that sandem compressor put too much load on the engine and sometimes there belt slippage.
whats your experience with any of this 2, how about u guys running the R4 in pre vortec motors/ 95- years.
thanks for any feedback,

I have owned my '93 for over 10 years now and not had any problems with the R4 compressor. The previous owner spent some cash converting over to R134A and it has always been a good cold A/C system. Even after converting to the 6.0 LS engine, it has been a reliable performer. I can't comment on the Sanden since I've never had one.


If you're looking to save some cash, check out this link on how to make the original R4 bracket from the old 4.3 V6 and 305/350 small block work for the LS engine. I did it and it works well.
