If you stop by our SEMA booth this year, you won't be disappointed...
the small frame EFR spool SO fast, i agree twinscroll is not nearly as big of a difference. The larger frame EFR's work great as singlescrolls with a T3 housing... But in twinscroll config their spoolup and response is the best ive experienced from any turbo mfg
Yes a vband version would be great. I may think of switching if this comes out. The results are great for the small frame versions, but the commitment to t25 flange makes upgrading a bit more expensive. If not Id opt for the 7064 just to leave it a bit more modular for upgrades. If there were a vband version in both small and medium frame that would be perfect assuming the outlet for all versions were in the same location and size.
I also like the wheel combos as they fit the suby a bit better with the larger turbine wheel (minus the required pressure ratios).
