Supercharged Hayabusa Engine 1340cc Big Power
This engine specification has been running in my DJ Racecars single seater since Alex Summers had the car in 2012 and I bought it in 2015 is very high specification. It’s been very reliable for me, and I ran so that I had two engines, swapping at end of each year to rebuilt one. Its specification has been improved at this rebuild to get some extra power but not been dyno’d to confirm yet.
