registered user Posted January 23, 2015 Report Share Posted January 23, 2015 I would think having windows in the pistons would help with flow but who knows, if your refering to stock cylinders then i would think the windows are a benefit for sure. i would even bet money on it. however on something like a cub or other cp cylinders im doubting there would be a hell of alot of difference in power either way. mostly because it has large boyesen ports. maybe there would be a small difference but im thinking it wouldnt be much we know for sure you dont need windows for long life of the wristpin bearings. windows couldnt hurt but arent necesarry Quote Link to comment Share on other sites More sharing options...
skywalker7374 Posted January 23, 2015 Report Share Posted January 23, 2015 Yeah I see your point about the cub cylinders not really needing windows that would make sense... So basically if you have high flowing boyesen ports you can go without the windows. Quote Link to comment Share on other sites More sharing options...
camatv Posted January 24, 2015 Report Share Posted January 24, 2015 your starting to maybe grasp the concept i figured out.... i can take pictures of the bottom of both a windowed piston and a non windowed i have both and both were ran in cheeta's the windowless are about 6-7 years old and have about 9 million passes on them.. would be interesting to see?

sheerider11 Posted January 24, 2015 Report Share Posted January 24, 2015 Wouldn't the piston with no windows force the charge into the transfers better? Quote Link to comment Share on other sites More sharing options...

camatv Posted January 30, 2015 Report Share Posted January 30, 2015 i think so. BUt it seems i have to make the boost ports HUGE> on stockers i also left the stock intake almost stock size. boost ports were the size of the stock intake windows and pointed in a way to aim the charge up the transfer instead of down. i also had to move and raise the transfer bridge a LOT. IF i could get stocker style pistons with no intake windows i think it would work better.. so there it is.. 1 Quote Link to comment Share on other sites More sharing options...

Wildcardracing Posted April 7, 2015 Report Share Posted April 7, 2015 I had at one time talked to wiseco about doing a similar project. I had planned to do mine as a flat top, any possibility of this being a future offering? Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted April 8, 2015 Report Share Posted April 8, 2015 what nobody usin the new flatops ?? man you be ballin with this shit Am I overthinking the benefits of how much more simple it is to design a dome with a stellar squish band on a flat top vs standard crowned pistons?
