Vf36 vs Vf37 spool up characteristics
Keen to hear experiences from owners & mappers on what differences they found between these two turbos. Specefically, looking at what RPM do they make peak torque at & peak boost. (Not too bothered with what max bhp they make as they are both very similar at between 330bhp to 360bhp).
-My Ver10 Hawkeye Spec C would hit 1.7 bar boost at 3,500 rpm and approx 380ft/lbs torque. (with decat 3" & Forge blue spring actuator)
-On the other hand yesterday, my Ver9 Blob Sti hit 1.65 bar boost at 3,950 rpm and approx 350ft/lbs torque. (with decat 3", Forge blue spring actuator & VTA breather system, Walbro fuel pump & Sard FPR)
Im not too concerned with the fact that the Spec C made more boost but want to know whether others have found such differences between VF36 & VF37 spool up rates? Can the Vf36 being roller bearing & lighter turbine/shaft & the Vf37 being sleave journal make this difference? (One is at approx 3500rpm the other at 3950rpm). (Other variables in above comparison is differences betwen Ver9/10 Heads, Inlets, Cams, & different dynos)
