word thats whats up!! thanks fellas
190whp?? help

would the dsm 14b fit on the greddy mani and still be a/c compatibale??
what's your power goal? when did volvos come with hybrids (what year and model is the volvo)?Would you guys NOT recommend a T3/T4 used turbo off a Volvo in a junkyard?With minimal shaft play?
do you even know what youre talking about? because a turbo is internally wastegated doesnt mean anything about a blow off valve. anytime you put a turbo on a car it is highly suggested that you put a blow off valve in so that your turbo doesnt get surges from the air when you close the throttle.no need for a BOV on a T25, i don't care what you're boosting, and that will definately shave the price. it's internally gated, so packaging is smaller.
ps. post #500 and it only took 2 1/2 years!!!
i apologize, i should have seperated those two statements. i was saying that there's no need for a BOV because THERE IS NO NEED FOR A BOV. NONE. modern ball bearing turbos can take the stress of compressor surge. hell, modern JOURNAL bearing turbos can take the stress of compressor surge (the stress really is that minimal. yes, it's axial stress, but that's why there's bearings!). the only reason to fit a BOV or BPV is if you don't want to hear the flutter caused by compressor surge. that's it.do you even know what youre talking about? because a turbo is internally wastegated doesnt mean anything about a blow off valve. anytime you put a turbo on a car it is highly suggested that you put a blow off valve in so that your turbo doesnt get surges from the air when you close the throttle.
the internally gated comment was because he was wanting to keep his A/C. having the turbo internally gated makes for easier packaging.
well a t25 does need a bov and most hybrid t3/t4's. at least the budget ones, because they are not ball bearing.
i ran a dsm t25 with a budget setup. i never had it on a dyno, but the butt dyno said about 180whp.
paid almost $500 for the whole setup. actually i'm thinkin about sellin the old setup -mani. comes with dsm 450cc inj, all charge piping(abs ftw!!), dsm t25(needs rebuilt) intercooler.
you can use an hf manifold with an adapter plate tho, on the cheap.

if you really want a BOV or BPV grab an OEM bosch
part number: 0 280 142 103 or 0 280 142 108 (better)
BPV and either recirculate it or vent it to atmosphere.

so if its not needed, why are everyone using them? why do stock turboed cars come with them? if theyre not needed, im sure car manufacturers wouldnt put them on because it would lower the price to make a reliable turbo car. ball bearings are not there to take the stress of compressor surge, theyre there to decrease turbo lag.i apologize, i should have seperated those two statements. i was saying that there's no need for a BOV because THERE IS NO NEED FOR A BOV.

not necessarily. wastegates dont always get in the way of the air compressor, the turbo and/or exhaust manifold does. wastegates can be vented off to either side or even in front of the turbo. only thing internally wastegated turbos are good for is price. its cheaper because you dont have to buy an external wastegate which can be pricey. internally wastegated turbos spool slower than externally wastegated because the actuator in an internally wastegated turbo starts to open several pounds before its target boost level. where as externally wastegated turbos wastegates dont open till the desired boost level. so ideally, if he wants to keep his ac but also get the best setup he could, he should look into exhaust manifolds that allow him to keep his ac and go with an external wastegate setup. is that the cheapest route, no. but keeping the ac and going turbo isnt normally cheap.the internally gated comment was because he was wanting to keep his A/C. having the turbo internally gated makes for easier packaging.
hf manifold will not allow him to keep his ac.you can use an hf manifold with an adapter plate tho, on the cheap.
my gt-four didn't come with a BOV or BPV. supras never had BOV or BPV fitted stock.
the reason manufacturers fit them originally was to muffle the sound of compressor surge. my gt-four had enough snorkels and resonators in the intake to start a full on swing band with brass section.
i was running 14psi on my gt2871r w/o a bypass or BOV with NO ISSUES. NONE. no boost spikes, no fuel problems, nothing. the only thing that made me want to install a bypass was that heads would turn when they heard compressor surge. i had someone ask me what kind of BOV i had because they liked the way it sounded. when i told them i didn't have one they gave me a look like i said i was using a potato.
yes, you can pick up a BOV for cheap enough that it's worth the peace of mind that you're not causing undue axial load on your compressor, but it's not worth spending $200 or $500 on a super crazy insane dual piston dodecahedral quad chamber rotary bypass. they all do the same damned thing, and their role is minimal at best.
both internal and external wastegates operate on exactly the same principal. higher end wastegates offer technology that prevents wastegate creep. you can get the same thing in a well-made wastegate actuator, from, say forge motorsports.
it isn't that the wastegate itself would get in the way, it's orienting the turbo and piping to allow the correct fitment of the wastegate that becomes an issue.
unless you're planning on building an insane monster of a turbo engine, internal gating will suffice.
