August 20, 200719 yr comment_192751 Wasnt sure where to post this one. Just wanted to know what a stock 4AC would be putting out in kw? I don't particularly want to embarrass myself by throwing her on a dyno and pumping out a whole 20kw but I'm curious is all. Does anyone know? Report
August 20, 200719 yr comment_192760 My spirit brochure claims 58kw, and a whopping 127NM of torque. Put it on a dyno, that would be so funny! Report
August 20, 200719 yr comment_192761 my estimate would be 40 rwkws from a fresh stock one, might get to 50 with a carb and exhaust. Report
August 20, 200719 yr Author comment_192803 So if I'm lucky i'd be pushin 30kw?? Cos its a bit tired. See what happens next time there is a dyno day around the place. Might throw it on there for shits and giggles, will depend on funds :P Cheers guys Report
August 20, 200719 yr comment_192806 Probly 30 if its pretty thrashed, does it go better than a 4k :P , cause an average 4k would put out about 30 kwatw. Report
August 20, 200719 yr comment_192842 lol my brothers old 4ac got dyno'd at 59.6kwatw... optimistic dyno or fresh engine? ....i have no idea Report
August 20, 200719 yr comment_192854 :P Thats pretty good, most stock bigports make about that. Report
August 21, 200719 yr comment_192889 :P Thats pretty good, most stock bigports make about that. They make power in the 70-75kw area.... Edited August 21, 200719 yr by Trev Report
August 21, 200719 yr comment_192907 For extra amusement pipe up a cream bulb dispenser to the intake and put methanol in the windscreen wiper bottle down there too :D easy 20kw :P Report
August 21, 200719 yr Author comment_192937 Probly 30 if its pretty thrashed, does it go better than a 4k :P , cause an average 4k would put out about 30 kwatw. it isnt overly thrashed :D came out of an auto ae82 with about 200k on the clock, doesnt blow smoke but it gets a work out when its due :yes: Report
September 10, 200917 yr comment_372867 i got 62hp out of my 4ac hahaha with 350+k's on the clock Report
September 13, 200917 yr comment_373563 My 4AC (110,000km) ran a 43kW at the flywheel, I put a Weber on and it run 43kW at the wheels now, about 63 at the flywheel. Report
October 7, 200916 yr comment_379847 Other than chucking a sports exhaust and different carb on there, what other cheap mods would benefit a 4ac? Or even just some certain tweaks that give them a bit more go? I've got a 4ac but I don't want to do anything major. One because I'm broke :D and two it'll be up for a re-con in about 50k anyway.
