Fastest Olds powered jet boat
« on: July 06, 2022, 08:36:12 PM »
What/who was the fastest Olds powered jet boat that anyone knows of here?  What was their setup?

I assume an AA impeller or steeper because lots of torque And not lots of rpm...

Just curious

A guy in Bullhead (Mark, I think?) has an Olds powered sled, mid 70s mph, but I don't know what's been done to it.

There was a guy on here 69 Kona, I believe his name is Lee. He was competing in the Top 10 with an Olds. I?ll have to see if I can find the thread where he was building a Comp Jet, I believe. It had an Olds as well.

Yes fastest I?ve been is 87mph .. pretty fast for a Oldsmobile .. we got quite a few seasons on the motor now . I had Bostick fluff up a set of edelbrocks and got the flow numbers up . Gonna stick them on a new shortblock one of these days .
