Racer Randy Williams built a really cool 1970 Challenger for the 2023 No Prep Kings drag racing. He initially purchased a rusted-out Challenger which he found rotting in a field in Nebraska and hauled the carcass to Jason Wood at Wizard Race Cars. After cutting it up, though, the men realized the car’s steel roof and quarters were too far gone … although the VIN plate and other odds and ends were still intact. Fortunately, some factory steel replacement panels and other fiberglass replacement parts from Glasstek breathed new life into the old car. The car was then painted B5 blue metallic. Much care was taken to maintain the integrity of the stock wheelbase and original body lines, although the hood’s height was massaged slightly to accommodate the massive intake manifold. “We had to play with the front end to get my fuel cell to fit, so we ended up cutting it into two pieces and re-molding it,” shared Williams. A BAE 521 cubic inch Hemi was installed along with a ProCharger F-140 supercharger. Randy Williams Returns To NPK With New 1970 Dodge Challenger
On another note, I am curious about remote mounting a centrifugal blower on a car powered by a (powerful) electric motor. Not the cheap gee-whiz tiny snails marketed on Ebay. Ironically, it would have some lag as it would have some delay between flooring it and full RPM being achieved, but, the plus side is close to zero parasitic loss when throttle was not needed much. So, like a turbo, but without the restriction of stuffing all the exhaust through a turbo turbine all the time. How much power do those blowers consume, I am curious to ascertain. Since Top Fuelers old Roots-style blowers consume around 800hp, I am sure a centrifugal would use far less.
I once had a Polaris Diesel ATV, slow as shit, but I always thought of putting an electric blower on it to give it more HP and speed.
BTW. it is more efficient to have a two-stage supercharger than a single-stage, which is why warplanes had a two-stage unit, in addition to having two available drive speeds. The charge air was only cooled after the second stage, but that makes sense as the compressors were coaxial.
