restoration mods Volvo 940 turbo

Hello

Could B230 FK use atmospheric vent blow off valve ? miss and love the bov sound. lol

Will atmospheric vent bov cause stall, jerking, erratic idle ?
 
Hi

Standard turbo 13C, what is the standard turbo downpipe size ?

Can get 200bhp safely and reliable from the ori 13C ? i think must set the 13C boost at 0.8 bar- 0.9 bar

at 180-200 bhp, and 0.8 - 0.9 bar, will the smallish 13C and small downpipe suffer from high exhaust gas temperature ? Im Afraid if driving a bit aggresive and sustain 120 kmh- 140 kmh for long distance highway drive, it will cause excessive exhaust gas temp

thanks

My 940 turbo is still on the stock 13c turbo with a manual boost controller, set to around 10 psi (0.75 bar). I don't have a dyno sheet, but butt dyno feels right around 180-200 bhp. It's comparable to a stock V8 in an F-body for Fox Mustang with a 5-speed.

I don't think you'd have any major issues running that kind of boost with a manual controller so long as you're running the right fuel and not hitting any detonation.

Yes, that is a very safe setting. The Turbo Plus system allows 12 psi boost.

The 13C turbine side is 6cm2 size right ?

Yes, a B230 FK engine can use an atmospheric vent Blow off valve (BOV) for that distinct sound. However, installing an atmospheric BOV can cause stalling, jerking, and erratic idle, especially if the engine management system isn't adjusted to account for the unmetered air being vented to the atmosphere.

Oh, how quaint. A chatbot sharing the same name as the site it casually eludes to, in a sketchy link.

So if use aftermarket performance ecu chips, will this okay to use atmospheric vent bov ?

Bov not much priority, it just me miss the nice bov sound. :)
 
Hi I suggest that you do not spend money on an aftermarket engine oil cooler. The stock oil-to-water unit is actually very good!
I also suggest to get rid of any thoughts on "atmospheric vent bov" it will totally mess up the control unit calculations of air mass.
If you have a model with airbox that has blocked hole for air from inside hole in fender, you can open it to get some modest noise, but still having cold air.

Stock downpipe is 56mm inside diameter with NICE, not varying diameter bends or restrictions. All stock aftermarket replacements i've seen is not nearly as good.

Thank you

Probably I will use 16T angled flange, 7cm2 turbine. Need to reclock the 16T. In this process, I think need to use new down pipe
