Below is some info on the chip Jim did for my '95 M3. You may wish to
reconsider using the word HYPE, although I doubt you did so derogatorily.
" Today we dynoed an M3 Lux at 273HP using ..
- Supersprint Headers/Exh. w/ Dr Gas crossover and stock cats
- Euro Airbox, HFM, and bigger Throttlebody
- Larger flow-matched ERT injectors
- Custom chip ...
This is the HIGHEST HP I have EVER seen on an S50USB30 motor that
has NOT been opened up ..
The HP Peak is a flat line from 6000 thru 7000rpms producing 220HP at
the REAR Wheels!!
Torque is flat from 4250 thru 5700 in the 200 lb/ft range (rear wheel,
about 250 at the shaft)
I can also say that we dynoed 278HP for the track with a catless
center section and a bit more tuning ....
And that is ALL she wrote for the S50US/B30 motor .. there IS no more to
be had !!
Note, that BMW race guru T.C. Kline said that the HIGHEST HP they
had EVER seen on a CSL motor, with headers/race exh. (no cats)
and all the intake tricks you could muster was .. 268HP .."
Dinan makes fine chips--Jim makes _great_ones.
Best to all,
