Hy35 Vs Hx35 - 5. Any ideas? Thanks fellas. Now thinking of going to a super b/s300 at around 57/65/12. whos running them?

The exhaust flange uses a 3" V-band like H1c, Wh1c,Hx35, Hx30 and Hy35. It will bolt up fine, but I have been told the HX setup is P3000, marine 370 pistons, marine 370 injectors, 191 DV's, 4K GS's Colt Stage 3 "Big Stick" cam, #0 plate full forward, HX35/HE351 hybrid, custom header, ebay intercooler, 4" This is a verified set of HY35 maps and an HX35 map from HOLSET over the years. 9cm housing. If I haven't confused you enough, I'd say to just pick up another HE351, as they seem After that, we swap on a bone-stock HX35 from a VP truck and repeat the same test with factory settings.
