Oh! & it`s a Genisis not cl,
My bad - sorry Fred! At least I got the list of mods right...
Rae's car made less power with an SNS chip?!?
The chip clearly wasn't suited to Rae's spec, probably for a more highly modified car - it was very rich! Was very useful for people to get AFR plots on their graphs, something we don't get at Aldon - but it tells you a lot about how the car's setup.
Just goes to show how much you get through transmission losses! Book figure for the 535i with the M62 lump is 232 bhp. And surely that Audi S3 book figure should is 225 bhp? Very similar amount of loss to the BMW.
Autobox losses can be huge, plus it's hard to get a true power curve from an auto - e.g. it might not deliver max torque 'til the higher gears, but you can generally only ever lock it in the lower ratios.
The S3 clearly had the hump with the dyno and had gone into a torque-limited mode. John'd seen that before on other newer cars, am sure if the owner had known what to unplug to stop it having a fit it'd make more power!
I think the figures look pretty good apart from the mardy S3. The lightly modded Clio 172 (renowned for not making stock power!) made around the book figures, as did Pete's well setup stock G40. Varley's 1W made 167bhp at Aldon previously and repeated that here - and the Civic is up on standard power as you'd expect from its mods.
I'm still highly amused that Robin's and Hayesey's cars are within less than 1bhp of one another! The only real difference is Hayesey has a BV head, whereas Robin has a stock one but 1341cc bottom end. The higher compression of the 1341cc comes in useful on the turbo'd motor though - lower down the rev range Robin's car makes 10bhp more than Hayesey's, even though Hayesey's turbo spools earlier thanks to the BV head.
