Awesome I have been looking for something like this.

why do you expect faster spool and 7% power increase?

What i like is that, by my math, you put out 15 lb/min at redline through the exhaust...so about 7.5 lb/min each....the 1544's efficiency max was at 6.3 lb/min, the 1548's are at 8 lb/min....so they should make better hp per psi.

they do look physically bigger in there...how long before two 2056s?
The exhaust sides (x2) should flow around the 2560's, while the compreser flows...a lot. I'm a little worried it my flow too much.

Now that the manifold has T2 flanges, all that needs to be redone is the downpipe. Unfortuantely that's the hardest part. With these turbos the downpipe covered one bolt hole so we had to drill a hole and weld a tube thru the downpipe and use a ~3" long bolt.

I should have layed the 2871 in there to see if it fit.

Hmm. I think slower spool, and I hope for more than 7%.

If spool is too slow I can always turn the anti lag back on
