holset h1c with bep housing

[Aproductions]

okay so with a holset h1c with a dsm bep housing.....can someone tell me what psi that is good for?....like where does the bep housing make this turbo efficient too?

thanks

Its not a matter of psi because you can't assume 100% efficiency. The turbo is rated flow wise for around 47lbs/mins in a bep housing. So depending on your setup, however much psi it takes to get there. So unless you plan on above 450whp, I wouldn't worry about it.

well like a t25 is good for 15 psi...so thheres no way to find that out for this turbo?

There are multiple threads about the efficency of these holset turbo's. If I were you I would use the search button before getting flamed from a moderator. And if you have to ask what psi x brand turbo is good to then I would just stick with the stock one bro.

I've been reading alot about this turbo too becaue I own one and will be hopefully dialing in everything new with ecmlink within the month. Supposed to spool like my 16g was but really wake up around 25 and continue until at least 35lbs.

25 and continue until at least 35lbs.

well I was asking people questions about my build(piston compression)
and they all said go with 9:1 but if the turbo doesn't wake up till like 25+.....then shouldn't i get 8.5:1?

If you plan on running 93 or e85, it shouldn't be a problem. If you running less that 93, I would recommend 8.5:1 to avoid knocking.
