- Untouched factory CNC’d cylinder heads!
What’s also noteworthy here is that if you’ve been reading up with the blog then you will see that the piston design chose by Harrop is very similar to the design I described in a recent article :
The piston used by Harrop features:
- Thicker piston crown for increased strength and a lowered primary ring for reduced ring operating temperature
- Thermal barrier top coating for better combustion efficiency with lower timing numbers as well as less localized heat transfer on the piston crown
- Dished piston (for lower compression) but with a raised outer ring for better squish
- Low friction skirt coating
- A forced side relief design with a longer skirt in the direction of rotation for stability and a shorter skirt in the perpendicular direction for reduced weight and friction
- Lastly: reinforced pin bosses for better load carrying potential

A beautiful example of a Hemi supercharger
Here is a beautiful example of a Hemi Supercharger setup in a 1972 Plymouth Cuda. The car is featured on mopar muscle magazine and is a gutted and tubbed ’street’ car powered by a 6.1 liter Hemi engine. The nicest touch on the car is the use of a water to air intercooler to cool the inlet charge, which gives a shorter route between the supercharger and the engine. This aplifies throttle response because the air has less distance to travel between mashing the big pedal and reaching the combustion chamber.
The setup:
- Chrysler 6.1 liter Hemi
- Paxton supercharger @ 10psi of boost.
- Custom air to water intercooler setup.
- AEM engine management system with dual fuel maps (for pump gas and racing fuel).
- TTI Long tube headers
- 3″ Dual exhaust
- The 518 RWHP was produced with premium unleaded.
