Very Tidy looking Turbo's
Just spoted these on another forum, a very clever idea by somebody!

very nice looking, but like that same forum asks, does it work?

balancing must be an issue

Wastegate pressures must be a bugger to balance. Imagine having FOUR turbos all spooling up at the same time! I would be interested to see if there is
any advantage to running that setup, though somehow I think it was more of a publicity stunt....... or was it

Hearing two slightly unsynchronised dump valves is a nice sound, imagine 4.

Was chatting to the chap on the from Owen Developments who built this setup.
It was a bit of fun to show off their skills and hasn't actually been run up yet.
Very clever guys at Owen developments. they built the FQ400 kit for Mitsubishi.
Apperently the guy from mistsy has already offered them a substantial wedge to buy that setup and put it on show in his office

Hmm, lovely bit of fabrication. Not sure it would work very well.
Normally the turbo would see all four (for simplicities sake) exhaust pulses.
i.e. pulse pulse pulse pulse etc etc
like this each would only see 1 in 4
pulse wait wait wait pulse wait ... etc.
Not sure what that means in real terms, but I suspect at the very least it isn't going to be easy to make work as well as a more conventional
setup.

thats pretty impressive,
Owen developments do all the mapping work on my friends corrado, everyone said he was mad to try 2 bar boost from a gt42 R turbo into a 9.5:1
compression engine, but owen just got on with it.

It actually reminded me of a tiny V8 I saw at a show last year.
I think it was 160cc and a true 4 stroke V8 with valves and everything! 
It wasn't running at the show - probably sounded like a thousand sparrow farts

I agree, I think you would have to join the exhaust manifold intogether and then split them again to go through the turbos?

Nice bit of engineering...but think of the lag!

It probably sounded like the ones this guy makes. Click on the video link to see/hear them.
There's some more here. The flathead V8 sounds great!
