Here is a (poor qulaity) shot I have of Craig at Lawrence Lake with his ASR "Floater Boat" - kilo record was 61+mph - he also ran it in BSR and it went about 72 mph as I recall.

Kilos were very fun stuff - but as is noted above, they were basically like running a whole different class with special boats, different props, different set ups.
