Lager turbo housing question?

[99red7.3]

Hey guys I'm wanting your opinion on what larger exhaust side I should get for my truck it's the one in my sig. Should I go with a 1.0 AR or the 1.15 AR? I pull a 11000 lb 5th wheel and am wanting to keep good power up top but keep my egts down I'll also be installing 4" exhaust at the same time.

Any input would be appreciated.

Thanks,

Evan

A "lager" housing will make your truck sluggish and may get you arrested.

Sorry i dont have a serious answer. I dont know.

The IPA housing is tits but the Stout housing has a creamy smooth power delivery!

Seroiusly, I remember reading some opinions that if you are into heavy towing the larger exhaust housing will actually hurt in the lower RPMs. Pretty laggy untill the higher RPMs.

i would do the EBPV delete with the high flow outlet from strictly diesel.
you need change out your turbo pedestal to the non-EBPV as well.
the high flow outlet is 145$ the new non-EBPV pedestal is 115$.
that set up will work fine.

Blue stroker do you know if that will help me bring down my egt while towing? That's my whole goal is to get those lower and not loose top end. A gain in top would be nice with minimal lower end loss.

Thanks for the input so far keep it coming

it is supposed to lower egts 100-200 degrees. i looked into doing this myself but the wallet wont permit at the time lol
i hope this helps.

Awesome thats great! thats what im looking to do is bring down the EGT's

Look into a van turbo will help egts. I don't just deleting the ebpv will really make a difference a lot of people delete it because it leaks everywhere eventually.

You should see how fast the turbo spools in my van. I can get the turbo up to 30psi in about 2 seconds with PHP's 100hp tune, but this is also without additional lag from an intercooler.

Under heavy towing you really shouldn't keep the rpms too low anyhow, so I can't see how the 1.15 housing would hurt. Also, great tuning makes all the difference in the world.

The common concensus between OBS and super duty guys is the 1.0 housing is the best. The super duty guys get a .84 housing, which causes GREAT off-idle torque and great in-boost characteristics (ie boost is always on-tap), but the .84 housing produces high drive pressures and a lack of top-end power. You SD guys get an IC to help with the higher egt's caused by this housing too. The OBS guys get a 1.15 exhaust housing, which makes torque suck *** off the line, but causes great mid-top end power. We aren't IC'd, so this 1.15 housing is great at keeping egt's down. But it also takes several seconds to build boost at nearly any speed.

the 1.0 housing always has boost on tap, has better drive pressures, still keeps egt's plenty low, offers plenty of torque off the line, and maintains great mid-top end power. 1.0 housing with ported compressor housing FTW for you super duty guys.
