Can't I'm in charge whilst bossman meeting our paymasters in Germany so not an option unfortunately. Thats why I had to have last week off to use up my annual leave.

Interested to see what BHP the 1125s are giving out and how the torque curves look.

First run, standard exhaust, 134bhp... Plots to follow later (all on the dyno machine)...

Just changing exhaust, installing lambda sensors, locking AFV then we'll log a couple more runs...

Ran with the first exhaust, 134bhp again. Fuelling was pretty much OK. I made some videos, but for some reason I cannot upload them to youtube.

Actually, thats isn't bad by any means. Being able to ditch the dustbin system and with it a few kg's as well has having a better sound and also not have to worry about fuelling sounds like a result!

Equal length primaries tested, bit lower on volumetric efficiency at the top end and a few HP down.

The first exhaust was pretty much spot on for fuelling, knocking on 12.5:1, you could probably trim it a little, but not really worth it for 1 or 2 HP IMHO. Second was a bit rich at the top end due to lower vol eff, if we trimmed that, we would still be down on power...

Will try and post the videos when I get home.
