This mornings episode of Horsepower on Spike TV did a whole big segment on the Snow Performance system. They installed it on a 572 cu. in. crate motor that pulled 700 hp on 110 race fuel. They removed the race fuel, replaced it with 93 octane pump gas and then installed the Snow system. It made less hp and they had to do some carb tuning. Reduced the jets from 92 down to 87 and fiddled with the timing eventually settling on around 40 degrees total timing and pulled 733 hp. Maybe the show is available 'On Demand'? Then they installed a system on a new supercharged Hemi Challenger.........
I just checked my DirecTV and they do NOT have Horsepower available for on demand. If you are on the west coast, you might still be able to catch this mornings episode.
