Re: RHB5 VJ11. How much power?
 

Which is exacty what happened. Ping was audible so the throttle was let off slightly then back at it. I was using a shitty bleeder style boost controller that I threw on in 5 minutes. I had only planned on running 10-12 psi and did so for my first 4 runs to get a baseline as my engine was newly built. It wasn't until the 3rd set of runs that I decided to up the boost from the stock solenoid. I slapped on the bleeder and went for a couple test runs in the front of the shop. When I was happy with a 16-18 psi hold, I went back to the shop. I overzelously gave it another turn and figured I'd get an 18 psi hold. I was wrong and it spiked to 20~22 psi.

Its not like internal gates are even reliable for anything over 15psi anyways, that looks like a typical dsm spike. Even on your previous dyno it shows how fast torque drops off, definatly not something that fun to drive... super fast spool, and dead on the top end. What fun is driving a honda that you cant bang out to atleast 7 grand?

Re: RHB5 VJ11. How much power?
 

My stock wastegate shouldn't see anything over 14 psi anyways and that is directly from the workshop manual. I have a ton of other wastegates that I'll be experimenting with but will most likely settle on the Bullseye wastegate on an IHI RHF55 VF39 (04~05 STI) and 18~20 psi with more tuning and a Profec B. Like I said, that was for baseline runs only and i didn't expect much. It's the stock turbo on the stock motor. 2.2 MX6 Turbo

ahhhhh, makes more sense now, lol... I thought this was a honda for some reason?.. Ya with a factory EBS you are going to see a much higher wastegate setting. When we put these turbos on hondas, the actual stock wastegate is set exactly 8psi. You kept saying 15+ psi, and I kept thinking to myself... my god, what stock d16 is gonna take that, haha. Anyhow I ran a pair of RHb5's on my twin turbo ls/vtec https://www.homemadeturbo.com/forum/...?topic=19375.0 Definatly a good turbo if you double them up ;)

Re: RHB5 VJ11. How much power?
 

Those aren't VJ11's though. Those are VF series out of the early Subaru's. The VF series have that flat inlet and you have to make a flange or use the stock flange. The VJ11 have the inlet as part of the assembly. They're still RHB5 but slightly smaller than the VJ11.

Re: RHB5 VJ11. How much power?
 

pretty much the same thing, because I actually swapped the center section from the Probe/mx6 into the subaru housings and it fits perfect, they look identicle. The only differences are the housings I beleve.
