Well from the Dyno Day Yesterday heres a result from a UK import mr2 . Forum : Techie On the Move Name : ? Car : sw20 Euro Spec Engine : 3sge Power : 138.5hp And the white 20v is way more powerful than any other 20v around these parts , apart from maybe Mr Motecs black top one . Here is a mildly modded 2zz , i think he had a apex fc , exhaust etc . Forum : Toymods Name: Mat Car: 2000 Celica Engine: 2zz Power: 157.7hp 117.6kw , 154.5hp 115.2kw We didn't have many Honda's turn up , well not as many that where going to come . All canceled due to mechanical issue , those dc2 intergra's normally pull 143hp atw , those engine's with a few mods normally pull some big numbers for the engine size . The euro's dynoed yesterday had lots of strange differences . Forum : Oz Honda name : yfin Car : Euro Engine : K24 Power: 135.6hp 101.1kw Forum : Oz Honda name: euro77 car: Euro STD manual Engine: K24A Power : 160.80hp 119.9kw Why the difference , one is driven harder than the other maybe . Also there have a very interesting ecu , it self adapts to the driving style used . The most powerful euro had feathered tyres in 19.000k's so i guess it must work . The mapping of these newer honda engines is very different to most cars , the air fuel ratio at throttle levels to pass euro 3 regulations is very lean . Then as soon as the rpm or throttle percentage is above the required level the air fuel drops to very rich levels to protect the engine . But there no fuel smoke from the exhaust pointed out by race engineer which was there , so there cylinder combustion must be spot on . Also another strange ecu function is the way the mapping is controlled by the vehicle speed and which gear is used . Basically the car is mapped more powerful in the lower gears than the over protected top gears . Looking at the rules for n/a engine a/f ratio if you could just change that function in the mapping those euro's would have had maybe 200hp at the wheels not bad for a stock production engine . Yes there along way ahead of most manufactures in the n/a engine design . [Report message to a moderator]
