wellI couldn't find the V-band flange for the BW 8374 EFR compressor anywhere so Igot a friend of mine to mill me one on his CNC lathe
don'tmind the fact that it looks like there is a space between the compressor sideof the flange to the pipe side, it's a consequence to the fact my milling tool wasn'tlong enough to complete the finish to the flange surface in one go, so I orderedone that should arrive next week to finish it off, then both flanges will beflush and a bit finer.

Hi guys, i've been following this thread for a couple of years and finally thought i'd post now that i've got my EFR up and running.
Very impressed so far with a transient response and the early spool.
Haven't lost torque anywhere coming from a td05 based 50 trim single scroll turbo but it really comes alive from 4000 onwards!
Evo 1RS
2.4 4G64
87.5mm Wiseco's
100mm crank
Eagle rods
8.8:1 compression
Ported head
FP4 cams
2200cc Id2000's
Walbro 416 and DW300 lift pump
AN6 fuel lines
E85
Autronic SMC
300m COP
MSD DIS4
BW EFR8374 1.05a/r
Twin 38mm MVS gates
3 inch dump pipe and exhaust
This is the result from my first tune, we ran into boost control issues as i had weak 10psi springs in the gates and the controller didn't want to pull it up past 22psi accurately. That 26psi run was a mistake and largely untuned with not much timing.
Also ran into cooling issues so we called it a day. Looking forward to running more boost as the turbo was just starting to come alive
