FB25 Supercharger Part 10: SC14 Up and Running!

Getting the SC14 setup running right, and benchmarking the performance.
Search tags:
2015 Subaru Forester 2.5i Supercharger DIY project. Eaton M65 (same internals as Eaton M45) from a Mercedes M271 engine. DIY Boost / Forced induction / Blower / Turbo / Intercooler on the FB25 2.5L engine featuring 0-60 testing, tuning using EcuFlash / RomRaider. Boost leaks, pressure testing, smoke test, brazing aluminum, intake baffle to quiet supercharger whine, supercharger rebuild, AP SureTrac R160 rear limited slip diff (LSD), Subaru clutch replacement, oil heat exchanger install using sandwich plate, installing a smaller supercharger pulley (65mm to 62mm) for increased MAP / boost psi. Upgraded to a Toyota Previa's SC14 for increased performance and on/off clutch operation. Next up, let's increase the SC14 boost pressure!

Love this video! Doing stuff that no one is! That’s my jam! Made my day when this popped up as a suggested video for me.

Seems very slow, for sure something is not right. Cool project tho, im sure youll figure it out. Seems for sure you should be making more than 2psi. What does the bpv setup look like? Whats it from? P.s. Watch out for undefined tables in ecu flash, they can be tricky and cause some real headaches.

Yeah it just occurred to me today that the SC14 clutch itself could be slipping, will test this evening. The recirculating BOV is an Greddy clone, has been working well. But the electric bypass valve is just an exhaust cutout valve (detailed earlier in this vid) and probably leaks a bit.

Just tested for clutch slip - there's absolutely none. So whatever boost I'm leaking is probably through my bypass valve. I'll wait until the smaller pulley arrives, test with that, and post an update. Thanks for watching / commenting, btw!

Dig it man! Really cool to see the home brew setup and learning new things!
