Not a knock or anything, but why would you need 2 superchargers to make 167 extra horse power? If Vortech can make a kit for the Ls1 engine (small 350) that makes 150 extra horse power, 167 wouldnt be too hard to obtain and it would keep the costs down greatly, right?

"Thank you for the comments,
We went with the twin blowers for several reasons, with two
units you have a much fatter boost curve. The engine comes under boost earlier and makes more low rpm power. Being that each blower is not working as hard as one, parasitic loss is comparable. With two superchargers blower surge problems are reduced and tuning is easier. This system incorporates an all
new blower design (developed for this application),it is not a Vortec or Paxton. The system also uses a balance tube and a special belt tensioning system (that addresses the torque loads
of two blowers). The crossmenber is replaced with a stronger
trianglated unit."

Also, what's that "only 167" more horsepower all about? Most Gen II Vipers make around 400-410 REAR wheel horsepower from the factory. Dan's 617 "rwhp" is at least 200 more than stock, and done on basically a stock motor. And, I'm willing to bet that 200 extra hp using the twin chargers is a lot easier on all the parts than only 150 more REAR wheel hp cranked through a single one on a stock chevy 350. I think he has a great package for the money!!! Anyone can make horsepower with any motor, but the more you make...... is always accomplished at the cost of either some drivability or reliability...... and, of course..... bucks! Ain't no free lunch!
Personally, I would rather sacrifice some power to keep a car more bulletproof, whether a Viper OR a....... GM thingy.
