Nice! I can't wait to see some results on it and the final pricing as well.

This is a true twin scroll design @Edkiefer and you have exactly the right idea about where the runners are directed.

Are you referring to quick spool valves found on some other systems, with regard to the flapper?

yeh, like old RX7 turbo II systems (1986-90 ) , they had a high an low port that was actuated at 5lb if my memory right .
the exhaust housing had 2 separate intakes scrolls to the exhaust impeller . The flapper valve(thats what I call it ) was part of the manifold .

Anyway , just wanted to know if what I thought was going on is right .

I think the flapper is called a butterfly valve.

well butterfly are round and pivot at center , this valve is rectangle in shape and pivots at end so no restriction when open , but anyway, its like a internal wastegate but with bigger valve that covers one of the 2 scroll ports .

here pic, go down to middle manifold one , 4th post, second pic . Used to work on the 13b a lot .

Anyway, there no valve here with 2.3 EB , thats important part

Nice to see some progress. Bgolden, I know you're helping and not the one pricing it, but to be a considerable option for the money, it's got to come down when compared to the 2 current options, and the third probably coming after SEMA.

[BGolden]

Well last they posted about a blown motor the entire community attacked the op. I don't think they want to go down that route again

Cute little turbo with hopefully a cute little price for big gains?
