Maybe on a ported engine.

SiH · October 14, 2008, 07:02:32 PM

With ports maybe.
I made just over 340 on (as far as i know) and unporrted block with .92 bar on 99 spec twins.

is the claim at the fly or the wheels? mine made 358.7 atf on 0.8bar on 99 spec twins!

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

FDAsh · October 14, 2008, 08:16:59 PM

320bhp at 0.9bar for me on standard twins.

Hmm, interesting - is that with a port? and who was it mapped and dyno\'d by?

307.2fwhp on stock twins at 0.8bar

Ricco_04 · October 15, 2008, 03:14:46 PM

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.

od404 · October 15, 2008, 04:09:13 PM

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.

306 fwhp @ 0.8bar with just a decat+backbox safe map by pip.

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.
