[s-cars] 80tq: 20v Project Update, 415whp, 12.25, etc

[Elijahallen92 at aol.com]

I just want to see all you guys line up and see who gets from one point to  
another first. I know its not fair to include those of us with lighter 20vt 
cars  but most of you have URS4/S6's so lets see it, I mean all this travel to 
see  your dyno #'s here and there, why not just have a drag meet, or a nice 
streach  of closed road that you can do a second gear at 4000rpm to 150mph RACE? 
Great  thread though guys, keep it up!

Add  another data point..
Some one pull their high HP motor already and put it  on a engine dyno.
I would love to see a comparison that way.

I would  also love to know if a 200 WHP engine losses the same drivetrain and 
 
friction losses thru the drive line as a 400 WHP.
I really wonder if  using a percentage to approximate driveline loss is 
really the way to  go.
