Power @wheels versus power @flywheel

[1975DCS]

We all know in the end you have less power @wheels then the engine chucks out @flywheel. But when I searched for an exhaust I came to the site of Supersprint whom for most cars have a dyno read out: nice! Interesting to see that Honda's have less transmission loss then a Renault (or other manufactures). It is also interesting to see what exhausts and manifolds can do on some cars. Anyway I always thought that my remapped Twingo RS, which did 117,3 bhp @wheels, would be in the 137 bhp @flywheels, but after seeing the results on Supersprint it is probably more like 140-145 bhp... Is that similar with other Twingo's that have seen the rolling road?

I have a rolling road day in a few weeks so i'll try and get graphs etc. Although I don't have an aftermarket exhaust

Me neither... Would fancy the R2 manifold, kat and custom silencer though...
