Is there anyone out there besides Mr.Peepers with a true twin scroll HX35 setup? Especially an 8 blade? What does yours spool like?
I built a real twin scroll manifold, and with a 12cm housing I'm not seeing anywhere near the quoted results. The manifold is completely divided, the internal WG is welded shut, there are not boost or exhaust leaks, and I have a 3" turbo back.
Starting at 2k, I see 25psi at about 4100, and 35 psi at 5500.
Mr.Peepers logs are showing 25 at about 3400, on his 7 blade.
That's a 700rpm difference! Is that the 8 blade larger heavier wheel showing up, or is something wring with my setup?
If thats all the better its gonna be, I'm tempted to put my 20cm housing back on to gain some flow back.
