kevin ribeiro Posted September 6, 2011 Report Share Posted September 6, 2011 i wondering if a 1.8 liter 4cyl engine can take a 320amp alternator or should a 270amp alternator work better any one running a HO alternator on 4cyl engines?

MECHMAN Posted September 6, 2011 Report Share Posted September 6, 2011 (edited) A 320a or 270a can work, it's a matter of load at idle and belt size and wrap. If the belt has insufficient wrap or is too small like a single-v or 4-rib it can cause slip. Proper tensioning and good belts are mandatory.

jsawdy212 Posted September 6, 2011 Report Share Posted September 6, 2011 it's all about idle amps that will put the strain on the motor when the RPM's come up it won't be as much as an issue. But make sure the belt has enough wrap and tension Quote 2007 caliber 2 Fi ssd 18's rd audio 3250 xs power d3100 (need 2 more) stock alt (soon to be singer 350a) 2.75:1 4th order in progress!

meade916 Posted September 6, 2011 Report Share Posted September 6, 2011 i saw my boy Jack (from the forum, and local to me), drop one of my old Chrome Irragi's in his Geo Metro. It was a 300a and it UNBELIEVABLY did great!! never heard it slip either. Thats more credit towards the installer then the product though because you wont get the same results unless you do it right, like he did.

LoudBimmer Posted September 6, 2011 Report Share Posted September 6, 2011 If you can, get 270a. It's little more expensive, but will be useful in future upgrades. Quote Link to comment Share on other sites More sharing options...
