Let me explain what "Horsepower Per Dollar" means.....

I opened a can of worms talking about the guy who wanted to run in the Silver State Classic. If you don't know-once a year the Nevada Highway Patrol works in conjunction with a motorsports organization. They block off a deserted section of Highway 93 and let people make top-speed runs. There's seversl classes-of course the one with all the glory is the over 200 mph class. R.J. Gorrileib's "Big Red" '69 Camaro accomplished this feat several years ago. You may or may not remember besides being featured in Hot Rod magazine- this car was in "Fast& Furious 4- I can't remember the actor's name- but the character was-"Big Daddy Dwight"-who was kissing the hooker's feet at the orgy when he got arrested for dealing drugs ( Falsely )  because he taunted Paul Walker-"Muscle Beats Import every time, Nut Sack"- drove this car in the movie. Any how-I got a bunch of questions "What about this car / engine combo?" "What about that one?" The answer to all of them is no, they won't go 200, and no it can't be built cheaper than my suggested '82-90 T/A with a Big Block Chevy for power. Here's a couple of the more entertaining ones of people who can't do math. # 1. What about a '70's Corvette with a 638 hp LS9 ZR1 LS motor?  Again- a '70's Stingray-while looking swoopy has a drag coefficient of .044. Only slightly less than a '70's T/A and still substantially higher than the .028-.032 of the '80's T/A. Secondly-An LS9 complete engine assembly retails for $22,900 through GMPP. That's more than double what a 650 hp 540 inch Rat motor built by Blueprint engines costs. That's eight grand MORE than the price of a 720 hp GMPP 572 Rat motor. A 610 hp 528 crate Hemi is $22,999 through Mopar Performance Huh? that's right folks, 8 thousand dollars MORE for roughly 100 LESS horsepower!!  Like I said-for hp per dollar the Rat is king. Here's another one: "What about a Buick Grand National with the boost turned way up?" "They were popular and competitive in NASCAR in the '80's." Yes the GN body was competitive in NASCAR-and occasionally ran 200 mph on long tracks like Daytona or Talledega. However their still a brick ( aerodynamically speaking ) compared to an '82-90 T/A, and that blistering speed was accomplished with a  paperthin fiberglass body over a lightweight chrome-moly tube chassis with an 750 hp small-block Chevy under the hood!! It wasn't a steel, body-on-frame-full-bodied car with a Turbocharged 231 inch V6!!  And GN drag racers-spare me your 700hp dyno sheets. Yes It's POSSIBLE to build a 700 hp Turbocharged GM V6; but not for anywhere near the low cost of a 700hp Rat motor! And one of those holding together for a few 1/4 mile runs while you put ice in the intake manifold between runs, is NOT holding together for a sustained 50 MILE top-end run!! And-you 9-second GN drag racers-your car still only goes 160 mph-not 200!! Guys-read up on physics. A couple guys were featured in Hot Rod a few years ago. They had a 750 hp Hemi in a '69 Road Runner which is only slightly less aero than an '87 GN- and they could only make 186 mph. To do 200 mph your going to need- like I said- at least 600 hp in a VERY light, VERY aerodynamic car-or like R.J. Gottlieb and "Big Red" about 850 hp in anything else. It's simple math fellas, nothing else. Mastermind
