Only 280 HP?

can make more but will need bigger turbo and less driveability
220hp atw would be perfect with a t28bb at 9000rpm.
Exhaust energy of normal 13b is comparable to Ford AU 4L 6 cyl
so halve or that energy is best with a disco potato sized snail.

Leon Prommet drove his single 12a for over 10 years in Sydney,
I had the chance to meet him in Sydney one summer day just as
he parked next to me and the seed was re-planted again after
reading about his efforts in ultra-lite and cars.

Standard 13B - Height 42 cm width 30 cm length 42 cm
Single 6.5B - Height 42 cm width 30 cm length 30 cm

why only one rotor though? that 6 rotor Redbul drift car drives ok

comedian :) - They R 47kg perfect for 600kg car.
fits light strong standard 5 speed gearboxes
from a 12a rx7 s1-2-3 or s4 even a six speed rx8.
With boost can make 280hp or more with big snails
NA about 170hp with halve the parts to buid a twin.
Also no valves, expensive rocker gear or all the
cost of building an NA 4 cylinder that weighs more.
Revs to 11,000rpm without issues of a twin due to
e shaft not experiencing reverse flexing etc.

I love it. If I was single, I'd be thinking about it.

ok you won me over. Funny thing happed when I was working at Ford. One day we got in an F250 rear brake drum, but it wasn't a drum.....it was a 20B rotor housing cos they use the same size box

So minus all of the above dribble what does it need to run in it's most simplistic form?
