Building a slant for torque
I'm always curious as to why people still even build those things.....
I always wonder why V-8 owners enjoy trolling on the Slant-Six forum. I own 3 1960's Mopars with slant, small-block, and big-block engines. I love just looking at the slant, which is a convertible which will always be rolling slow and cool. I even own two 1980's M-B diesel cars just to tic people off. Fuel with bio-diesel (buy at pump in CA) so less net-CO2 emissions than any battery car.
Re the question, I'm waiting for better e-motor boost systems. Seems a simple way to overcome the poor breathing in slant heads, without the complexity of a turbocharger or supercharger. Current ones ~$1000 actually work, but the controls are crude. Costs will come down and probably better controls to control pressure output. You don't want to overboost at low rpm and risk melting pistons. If an EFI system with MAP sensor (for boost, to not clip signal > 1 atm), fuel should properly adjust. Perhaps the company now making an MPFI intake manifold for the slant will someday add an option for e-boost.
OE manufacturers might someday change to e-boost, allowing leveraging them at junkyards. But, I'm guessing the transition to hybrids will limit that since the e-motor already provides torque when needed, and especially in plug-in hybrids where the gas motor is used mostly as a generator. Another thought is adapting the small supercharger in 2000's M-B Kompressor cars, which might be a good fit to a slant. I've seen used ones inexpensive on ebay.
