Hey guys so im going to have a crack at the kilo record over here in aus for 1250cc mono. its currently set with a boat the same as mine but with a 920cc on it at 83mph i think it is.

Im wanting to have a go at it but with a 814cc.

I have a hustler 75hp, Phil's mod 50 pistons and the matching rods, im going to use my straight in 5pedal front with the 1inch carbs on it.

what im needing to know is what should i do it it, it'll be fingerported, but im thinking it'll need to be spinning well into the 7's
i also know this motor will only be good for a kilo run not normal circuit racing..

my current motor does 75mph, its 814 fingerported with a single throat front, 2-1 gear ratio and 12x23 @6500rpm.

i have 2.4-1, 2-1, and like a 1.85-1 gearboxes for it and many props. 12x23 12x25 13x23 13x27 and so on.

all help is muchly appreciated!

850
