yeah some learning curve! can make some big boost at low stress levels for the turbos, the way i look at it is a turbo compresses via ratios. so if its a 2:1 for eg, feed in atmospheric and you get 1 bar over atmosphere, but ram 1 bar over atmosphere in there and its pumping out 4bar....

will need some stout boost control!!

is this the first compound turbo bug???

This isn't the first compound setup in a bug. Wally did it years ago on his 1200 challenge setup. The engine didn't last long, had a bearing failure or something like that and the project got shelved. I have a friend that has a dragster with a very similar setup. He has a bypass valve between the turbos in case the big unit starts moving too much air. It hasn't run down the track yet.

I'd like 350whp+, not sure I'll get it, but I'll sure try!

Love it! Can't wait to see drag vids. I always thought using a short cut through the shroud was a space saving method. Glad to see it being done.

I figure that the fuel and ignition systems can support it, the turbo system should easily support it. I can cool hot pressurized air in 2 different ways, and the bottom end should be pretty stout too. Why not put it to work and see what comes from it.

I don't know that I'll keep the through the shroud intake on version 2.0. It looks cool, and packages nice, but it sure makes working on things a chore. I've had it this was for 6 years now, i think its about time for some reconfiguring.

Maybe V bands instead of flanges on both sides of the shroud.

I have a silicone coupler on the back side. The 4 bolts into the shroud work fine enough. Just tight to work behind the shroud.

Compound, yes. Everything I've seen shows big turbo feeding the small one.
Cool! I build that with the 1200cc if you remember. Pity I could not get results from it.
Space is the major isuue usually

I remember your old setup. I actually mentioned it a few posts before this one. I hope it gives good results. Not a big deal either way, its pretty easy to swap back to the big single or even the little subie setup if i need to. It'll be a fun test either way.
