That\'s good, mine only makes 320 at .9 bar on stock twins, 1993 though.

322 stock motor and tubbies, 95 fuel uprated smic 0.85bar.  

Big difference on who maps, how agressive and how accurate the readings are tbh.

When I bought mine it was making 292whp (according to the dyno sheet) which is roughly 350 (assuming 18% power lost through the transmission).  Mine is a street-ported engine with ARC smic, filters, full exhaust (inc. downpipe and decat) and running 0.85bar on stock twins.

It\'s now running at 1bar, but I have no figures for that.

As said there are big differences depending on who mapped the car, what dyno was used, not to mention how many different setups we all run.

As far as i\'m away its got stock porting, when i brought the car it had a 2nd hand rebuilt engine placed in it that had done 4000 miles.  I presume theres no way of telling what porting its had done other than on the reciept, which doesnt state any porting!

Was mapped by Max @ ReWorx just over a month ago - he suggested i leave it at 0.8 and was very pleased with the way its running.

you should be getting at least the same as mine. i havent pushed mine for outright power my exhaust is still quite quiet with a silenced de cat at around 96db. so its got enough power but is very nice and relaxing on a run :Thumbs-up
