Just saw this from the GSL boys!! They're aiming for 6-700hp with 4.5L stroker and bigger fuel pump.

ohhhhh this is nice, about to do a compound setup on my 1hdt with a Hx30 but cant decide on a hx35 or 40 as the bigger turbo. what do you guys reckon?
 
I would love to see the dyno sheets on these, i wouldn't have thought that 2 turbos will net a big advantage over a properly setup single turbo, these motors have a small rpm range and i have heard of people running into issues with boost before 1600rpm? Is that a thing or a rumor? obviously not built to be to much of a daily driver. Would be interesting to know if compound turbos could make a good daily on the fte, I can imagine needing a built trans and axles to cope with such, in a reliable way.
 
Only if someone had a bolt on solution this would be awesome. Anyone have compounds with VNT turbos?
