smacko84 Posted August 20, 2007 Report Posted August 20, 2007 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? Quote
Trev Posted August 20, 2007 Report Posted August 20, 2007 They ranged from 57 - 67 flywheel Kw's. Quote
LittleRedSpirit Posted August 20, 2007 Report Posted August 20, 2007 My spirit brochure claims 58kw, and a whopping 127NM of torque. Put it on a dyno, that would be so funny! Quote
Robert Posted August 20, 2007 Report Posted August 20, 2007 my estimate would be 40 rwkws from a fresh stock one, might get to 50 with a carb and exhaust. Quote
smacko84 Posted August 20, 2007 Author Report Posted August 20, 2007 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 Quote
Robert Posted August 20, 2007 Report Posted August 20, 2007 Probly 30 if its pretty thrashed, does it go better than a 4k :P , cause an average 4k would put out about 30 kwatw. Quote
andro0o Posted August 20, 2007 Report Posted August 20, 2007 lol my brothers old 4ac got dyno'd at 59.6kwatw... optimistic dyno or fresh engine? ....i have no idea Quote
Robert Posted August 20, 2007 Report Posted August 20, 2007 :P Thats pretty good, most stock bigports make about that. Quote
Trev Posted August 21, 2007 Report Posted August 21, 2007 (edited) :P Thats pretty good, most stock bigports make about that. They make power in the 70-75kw area.... Edited August 21, 2007 by Trev Quote
beerhead Posted August 21, 2007 Report Posted August 21, 2007 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 Quote

55LDE Posted September 10, 2009 Report Posted September 10, 2009 i got 62hp out of my 4ac hahaha with 350+k's on the clock Quote
67Rolla-Ken Posted September 10, 2009 Report Posted September 10, 2009 How the hell did you even find this thread?? :jamie: Quote
Gecko71 Posted September 13, 2009 Report Posted September 13, 2009 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. Quote
Silver_Seca_AE82 Posted October 7, 2009 Report Posted October 7, 2009 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.
