Very exciting! Great work!!!

Damn!!!..That is why I love this Forum!
that build is SO .....I'm speachless..!!

4 Rotor = The Holy of all Holies. The engineering and fabrication in this project is inspiring.

O my god... I think I just jizzed in my pants...

I am so in! This is awesome.

looking good, really good.

i just recentl learned why i is best to keep the intake nice and straight, and explains why Mad Mike gained some HP on his most recent engine modification and another 500-1000 rpms.

i have seen somewhere before that aluminium centre plates wouldnt hold up to higher rpms as the bearings work themselves loose and on an engine such as yours with all the time and effort into building this bad boy the last thing you want is a bearing wrecking everything.

i take it you cant show us the eshaft? is it something you have designed and made? 3 piece?

did you think to try the engine cooling like mazda did or was that too complex?

looking forward to the progress, the build and the start up :D:D:D:D:D:D

thanks for sharing too

Just amazing. Cant wait to hear the sexy sounds it will make!

I'm speechless O_O realy impressive seriously props to you

Awesome - Going to be following this one very closely :cool:

Love the new firewall. Engine is a work of art! I hope you have a high quality video camera to capture the sound when she runs :)

What metals are you using that "cant be welded"? :scratch:

Dear mother of god!!!

What? You couldn't spend the extra cash and do a 6 rotor? :P Awesome job!

Incredible man! Impressive as always.

Such an awesome build!

Brass to aluminum. At least not that I am aware of or willing to try. Plus I didn't want to risk hurting the diameter tolerance.

Thanks DJ!

Super clean work. Love it.

great setup, definitely some thought gone into that!. I hope the needle roller center bearing doesn't drive you crazy.

What is it noisy?

Wow, awesome work. A build thread actually worth reading here....

Can't wait to see some numbers... GREAT build, again.

This is my new favorite thread of all time. :D

This is just all out crazy! I was completely blown away with your S3 article, but this is going to be on a whole other level! Good luck with it and I am anxious to see this thing come together. Best of luck.

Random, but are you manufacturing your front splitters with '93-'95 fronts for the masses?

nice 4 rotors build, cant wait to see the engine start up!!

Thanks Grant! I didn't photo the eshaft, was always in a hurry. It's a custom 4-piece unit, so trick. I am releasing a video that has a bunch of footage showing most of the internal parts. Stay tuned on it :-)

I was going to do center cooling, but the center bearing feed tube made it too complex. Had to skip it. The external method is rather nice still, so not too big a deal

Thanks! No plans to make splitters unfortunately
