I'm gonna run it some then see how fast it will go. It's 13800 in the video.

020 off the key

190 lbs of compression

If squish is the same, why would the compression be different?

Squish and base dont have to be cut as much to get the ex down.

So wouldn't more squish cutting raise comp even more?

I probably have it backwards.

 

[jmssaws]

I cut 050 from the chamber but I did it on a decent angle to keep compression around 200lbs.

It takes 070 from the chamber that get 230-240 where I live,they don't need that much though.

This saw is a good example of what widening the ports dose,it gained some from it but the biggest gains by far is compression and timing.

It runs better now but not by a huge amount.

 

[jmssaws]

I'm gonna turn it as fast as it will run and see what we got.

I think that's what everyone wants to hear

I've been noodling with a 32" 404 8pin and it likes the longer bar. Video loading.


I've ran 2 tanks through it since new and it's beginning to free up.

 

[jmssaws]

It's strong fellas

 

[lwhaples]

Awesome.

I'm leaving the circle crank out of this saw but I'm not done messing with it,I'll build another saw and try it again.

That saw is gitting it!!

Nice work, thank you for sharing.

Curious to see what a twin with the circle crank would do.??

 

[jmssaws]

A twin?

 

[mdavlee]

Well I am very curious to see where this go's! I have a 281 piston sitting here, I think I'll try it out in my 064 next time I take it apart.

There's some wiseco pistons for sale that fit 046 and 281. The ring I'll eat up the lining so you have to have it replated.

Chamber size.

I ordered one yesterday, for a 660 the number is 1122 790 9102

My 660 stock brake handle (1122 793 9103) works perfect with my full wrap pro safety handle. No replacement needed.
