273 Supercharged...ITS HAPPENING PEOPLE!!

How much more power does the 727 use over the 904?
You state the Paxton will eat power. How much HP is required to turn the unit?

The answer is a lot less than most people guess. But if you in fact have numbers, I'd like to know.



Same question as above. ^^^^

Sure, it takes no power to run a belt driven blower and a 727 will have exactly the same loads and internal friction and rotating mass as a 904. ...sure, whatever...
I'd be thinking that on a tiny little torqueless engine like this, with only 5 psi of boost, that every little thing would help, cutting down the weight of the trans, cost as well as the decreased internal drag and rotating mass would be a plus, but obviously, you think that's not the case and fitting the extra "lump" would be the way to go...

The last time I changed out a 727 to a 904, the car picked up almost .4 in the ET. From memory that worked out to about 8 percent.
