I have seen many Dynos in european magazines. When new the car dynoed 175 hp after a couple of thousand kilometres it dynoed 182 hp.

but i don't have a dyno scanned, sorry. Trial's header dyno should give you an idea as well. That car has an exhaust, header and 105 octane gas. In europe most places can have access to 99+ octane gas. Trust me it is the difference in octanes that gives the extra hp. The ECU makes full use of the higher octane gas. When I use gas with low octane rating there a noticeable loss in hp.

Brad it is not just uk cars. it is both japanese and european cars. They have a different ECU and different emissions control (EGR). I haven't seen any US stock celica in the 175hp area. have you seen trial's dyno?was it in ps or hp? i cant remember

I think european cars have larger front discs. i am not sure though. even parts like the alternator pulley are different. people had difficulties installing a UR pulley on a european car.

I know there is a difference with ps and hp but I am quite sure that the difference in hp has to do with the gas octane rating. What do you have in the states 87?

phil c i didn't know about that.

And the Gt model in europe is listed with about 143 hp which is the same with usa.

Following the same logic then the t-sport is 12hp more than the usa model
