Re: 202 RWHP Dyno Chart

The car is a 2003 BMW 330 Coupe. It's interesting that a lower (advertised) powered car is making more RWHP than our "238" HP 8.

They rather maybe underrate their engine a bit. Good choice IMHO. The most extreme case of underating is the NEON SRT4. It is advertised as 215 HP but on a dyno it puts down anywhere from 205-215 WHEEL HP!!! Same with the late Z28. Rated at 305 and it put down 290+ at the wheels. (ls1 engine).
Some manufacturers have had both. NISSAN really OVERrated the sentra SER spec v! rated at 180hp at first it only put down 138hp at the wheels! they rerated at 175 but that too is overating oh well. No such problems with the 350z which puts down consistenly 235 wheel hp stock.
If I were a manufacturer I rather UNDERATE a car. That first eliminates any disapointment from false expectations also helps lower insurance costs of ownership.
(all #'s posted are DYNOJET examples, mustang type and dynopac dyno numbers differ)

i believe hp # sell cars
so they would rather have as high hp output as they can put down on paper
also, i don't know the % of owner that would take their car to a dyno or look at web sites to find out the dyno figure of their cars. so they might prefer to lie at the beginning, and then later on do a cover up
oh wait, or is it just Ford that has been doing this?? :D
