Chevrolet's new-generation of all-alloy V8 engines are absolute
gems! Although retaining pushrod valve operation from a single
central camshaft, the LS-series engines are nonetheless
technologically very advanced and refined engines, revving up to
7000 rpm.
Powerful and possessing massive torque, due to their large swept
volume, they are also very reliable, as they do not need high
levels of race tuning, and, remarkably, they are almost the same
(low) weight as the BMW M60 in race trim, which is a testament to
their state-of-the-art design.
With 7 litres of raw power and
torque, the LS7 is the most powerful engine option for the Aquila
CR1 available.
The LS7 features cross-bolted main
bearings, titanium connecting rods and sodium-cooled exhaust valves
- a very sophisticated piece of kit. The LS7 is obviously best
suited to classes with no restrictions on power or engine capacity,
or to classes restricted by power-to-weight ratio run on high-speed
circuits, where the high power means high straight-line speeds, and
the high torque enables carriage of considerable ballast without
undue loss in acceleration performance.
