Dyno database anyone?
Posted this in C3 tech figured may as well here too.
With al the claims out there with internet land it would be interesting to see what these cars put down to the wheels.
Say we form a pool, ea kick in a couple bucks to get someones car on the rollers and post the results combo from fan to tires. Doubt CF would allow some friendly $ wagers but could even offer some type of freebie for the closest guess.
Must post as many details about internals as possible from gearing, internals head flow etc.
Varying tire pressure, engine temps...could run pizza cutters out back for run 2 that type of thing.
Or has it been done to death on these cars and not needed?
Thoughts?

Are you suggesting that we post what the build is and then guess the dyno results? Or a database of engine builds with the dyno numbers? Or, possibly that we (a group of members) manage to meet at the same dyno and get some numbers? (Would have to be the same dyno on the same day to get consistent comparisons. That would be a fun event.)

Or we create a sticky with a table of known engine setups and results? With columns of data like (fictional example):
login infomanss
block GM 350 iron
crank Summit 3.75" cast
rods I-beam
pistons Hypereutectic
heads GM Vortec L31
cam COMP Cams XR276HR 276/282 .502/.510
lifters COMP Cams Hydraulic Roller
rockers COMP Cams Aluminum Full Roller 1:6
intake FIRST TPI
throttle body FIRST TPI 1050 CFM
engine mgmt F.A.S.T. EZ 2.0
hp peak 350
hp rpm 4500
torque 510
torque rpm 2500
method engine dyno
notes tested at blah blah conditions with E85 fuel and Hooker long tube headers
EDIT NOTE: ewww this came out ugly...try to imagine a table of data :-)
