Man i'd like to have an efr turbine on my delta for the 'big' turbo....
Everone on performance engines is switching to efr if possible right now. They are a work of art, makes the garrett gtx series look like something from the past.....
Garrett only do rnd on the turbines... borgwarner reworkes the complete case,turbines,shafts,wastegates everything.... those things have a verry wide effective range allow for higher boost as garret eqivalents and spool faster...
This however is a variable 'inlet' Twinscroll Turbo... it's body looks like an efr..... however twinscroll turbos are mostly big, the smallest efr is rated for 300-400bhp (petrol)
Those inlet designs are simmilar to quick boost valves, they reduce turbine inlet diameter (smaller innlet greater gasvelocity)
