Not even close. I have a '78 Fiat X1/9 streetcar, with a built 1500 motor,
including 10:1 compression, big cam, ported/polished head, twin 40mm webers,
header, + custom exhaust, light flywheel, etc, etc..... And it dyno'ed (on a
dynojet machine) at:
83.4 rwhp
82.5 rwft-lbs.
see http://members.tripod.com/yugopwr for dyno sheet.
A DSP 1500, with crappy cam, stock head, and stock 8.5:1 compression isn't
making 100 flywheel horsepower. No way. No how.
I wish it could.

Yep. I figure with my steetcar, I'm around 100-108 flywheel HP. My motor
would put me smack into D-mod, not even DP! A realistic number for a DSP Fiat
with 1500 is ~80 horsepower or so.
