Octane My new engine build

[speedysprocket]

My 93mm bore cylinder just came! They're sitting on Polaris cases with a brand new stock Octane crankshaft (70mm stroke) that'll make me a 950cc Polaris engine for my Octane! Bringing them to Richmond today for the porting and assembly!

nice! looking fwd to see how it runs, puts ideas in my head for my octane. watching this..

 

[egbrig]

Yes, I think your arms are going to get longer!!!

 

[speedysprocket]

I hope so! Octane is going to demand some respect!

 

[StandupWI]

This is going to be awesome!! Do you mind sharing where you got the cylinder? I assume they are off a liberty sled engine?

The Crank Shop in Vermont.

You gonna post the hole engine build on here....would be great and what Pipe are you gonna use?

 

[speedysprocket]

Low profile power valves should let me keep my B-pipe.

 

[Shane1989]

Any news on your engine??

 

[speedysprocket]

More pictures. Crank Shop valves had to be cut down to fit the Dasa assembly. Cases are bored and ported. Head will come from Power Factor after the crank and pistons are set in for measurements...

That thing looks good Alex, cant wait to see it in the hull running! Looks like it wont be much longer before its ready to roll!

 

[speedysprocket]

Just waiting for some measurements so I can get a head made!

I think this build is awesome, and its sweet to see people trying different things. Do you know what the cylinders are from? I know they are big bore cylinders for a sled, but what sled? I assume the sleeves are custom made for ski porting too? I think this thing is going to rip!

 

[speedysprocket]

They're custom cylinders. Same ones EME uses. No sleeves, it's a nikasil bore. Porting was requested when ordered then cleaned up by my builder...

 

[speedysprocket]

Cylinder head! Getting closer...

 

[egbrig]

Alex, we are very close. Here are some pics of the Low Profile P/V's I made today bolted in. Just waiting for a seal and C-clip and I can put all together.

 

[speedysprocket]

Erik, I can't wait!

Looks nice.

That looks great Alex! I like the low profile power valves. I thought Malone cylinders weren't set up for low profile valves, what's the deal?
