matth76 Posted February 7, 2009 Posted February 7, 2009 I have see a lot of references (mainly US) to the mark 1 350z having 283bhp (287ps). Whereas here in the UK we have 276bhp. Do the american 350's have slightly different ecu's to account for this small change in factory quoted performance? The US version also has more quoted torque at 274 lbs/ft compared to the UK's 268 lbs/ft. Thanks for any info. Quote
matth76 Posted February 7, 2009 Author Posted February 7, 2009 The US have a lower octane fuel as standard compared to us. I can only assume they use the JDM ecu which seems to be a mystery as to how different it is to the UK one ...and perhaps they do in fact liberate more power from the engine. Anyone know about the US cars? Quote

lotuscc Posted February 7, 2009 Posted February 7, 2009 The difference is the higher octane fuel used in Japan (100). Octane in US varies state to state. They use a different system of measuring octane so although a US octane rate might seem lower it could be the same or higher than ours. Quote

Most common over there is 87 though, so 91/92 which is still popular in Eastern Europe. Quote
matth76 Posted February 8, 2009 Author Posted February 8, 2009 Cheers guys. Anyone know what may account for the increase in factory advertised power though? Quote
BulletMagnet Posted February 8, 2009 Posted February 8, 2009 In America everything HAS to be bigger and better.... either that or the power increase is to move their McDonalds induced bodies about... Quote

Ekona Posted February 8, 2009 Posted February 8, 2009 The bhp difference could be down to the slightly different way they measure (or used to, anyway) it over there, but not the lb/ft figure. To summarise, I haven't the foggiest! Quote
