Drivetrain Project 1.8L Rotrex SC Stroker
Wow 22lbs with a high flow everything is plenty of boost.
So, are you changing the pulley to something a little larger to slow the SC rpm, or are you saying that it just will theoretically be lower due to a larger combustion chamber or piston design?
Also, can you share any pics of the Rotrex mounted? Some pics that are maybe a little more 'work in progress', as it was going back together.
Thanks for sharing your awesome build with us.

the production kits are slightly different from LBs especially all the black paint
We have tweaked a few things, also using a different waterpump design which is also lighter. Things are looking very good. All parts are finished now in final design. Waiting on manufacturers of those parts to get them all to me. Then final pricing will be complete

Hey, I wanted to say thanks to all you guys for the kind words. I almost stopped posting because of all the BS that's gone on here and on other sites. It's really cool to see so many guys I respect on here posting . My goal is to share and have fun doing so along the way. I'm done responding to the 
people. It became a kids game that I'd rather not play. Again, thanks for helping to make NAM a cool place to share again

You are not taking engine over 5,000 rpm? What have you been told about engine break-in technique? Not to hijack this thread, as this is a controversial topic. But some believe running hard seats rings best, and they are the only things which "wear" in. And you have to do it before the cross-hatching of the honing is gone.

Not taking it past 5K until Jan changes to the tune so thing's don't go POP

I didn't have time for a re-map between my travels. I've been out the country a lot over the last couple months. I'm finally home tomorrow for a good while. Man I can't wait!
