Being that I missed the original muscle car battle of the late sixties to the early seventies, I am paying very close attention to the new (And possibly last, thanks to upcoming emissions standards) battle royale between Detroit’s finest V8 cars. I was so excited to read Motor Trend’s  comparison back in June between the stock versions of the Camaro SS, Mustang GT, and Challenger R/T. These cars embody so much of what I love in a car: style, simplicity, raw power, and that oh-so-sexy V8 growl. I must have read that article ten times.

Then I got the mail the other day and nearly fell over when I saw the December cover. When words like “Hennessey”, “Shelby” and “SpeedFactory” grace the cover of a magazine, you know you’re in for a good read. In so many words, the Hennessey Camaro made a little less horsepower than the Shelby pony but whipped it on the track due mostly to a better handling package and stickier tires. The best news for everybody is that the claimed “650″ horsepower by Hennessey is in fact a gross understatement. On the dyno, the HPE650 made 612 at the wheels! Using a 15% drivetrain loss, this puts the Camaro at over 700 to the crank, well above the claimed amount. Sweet. Now Hennessey has their LS9-swapped HPE700 which has 645 rwhp…wait…only 33 more? I don’t know the package pricing, but I imagine that the HPE700 is much more expensive. I’d be anxious to see it go against an even more tuned GT500 and a 7.2L Challenger. We shall see.

I think those were the words that Ford Racing Parts engineers told droves of 2010 GT500 owners when asked about what was coming out for the new ’stang. FRP has introduced a few different supercharger options for the prized pony, but the mack daddy 750 hp upgrade is the one to watch for. With a 2.9L blower and a Whipple MAF, the FRP kit is no joke. It’s the only kit (to our knowledge) currently available for the new GT500 and seems like it will rip the doors off of just about everything else out there. Has anybody seen real world RWHP numbers?

After keeping us waiting for a couple years, Whipple Industries has recently unveiled their new line of twin-screw superchargers for the GMT900 platform trucks and SUVs. The superchargers cover all motors from the base truck 4.8L up to the Cadillac/GMC 6.2L and can provide a claimed 85% increase in horsepower. Whipple states a 25% loss through drivetrain components which gives the 5.3L Tahoe that they tested an estimated 586 crank horsepower (an 83% increase). Does that mean that a 6.2L Escalade or Denali would be pushing 745 crank hp?! If so, this forced-induction nut will start saving his pennies for one! Check out the video below for some of that sweet blower whine that we all love.
