rwhp converted to flywheel?
I thought the standard for loss of hp through the driveline (fbody) was:
m6< 10-13% loss
a4< up to 15%
Vettes lose more through their driveline, so it's probably more like 17% loss for you.
670 is probably the closest guess of your flywheel hp
Anyone else use this as a guide?

I calculated about 636hp what's your guess!

Still wondering why % are used. I wouldn't bet on a % being accurate.
Example 1 a big block blown alcohol car that makes 2000 hp at 7000 rpm with a manual- alcohol cars have no radiator thus no water pump or other accesories besides the blower itself vs.
Example 2 a small block with all accesories and an auto making 500 hp at 7000.
example 1 : with 15% loss = 300 hp loss when compared engine dyno to RWHP
example 2 : with 17% loss = 85 hp loss when compared to an engine dynovs rwhp.
thats a joke. %'s just dont work.
I would bet all accesories add up to about 40+ hp and the auto trans would steal 60 or more unlocked at 7000 rpms. VS. a manual like a lenco which would rob very little at 7000 rpm. Nevermind driveline losses.

% is linear across the curve, the more you make the more gets lost as heat buildup in the motor and driveline...and it could take upwards of 300 hp to drive a blower that big at that hp level

An engine dyno accounts for the blower loss. Are you telling me it doubles its penalty once installed in a vehicle?
NOT!
%'s only work when calculating air temp differences and compression changes.
