hey guys my turbos are toast from all the turbo bark i need to put a blow off valve on my truck dont really want to drop $600 on the one from bd i'd to do a custom
setup any help or ideas would be great
thanks in advance
you need a bigger than stock turbo for your mods, you should be at size 5 or 6 with your mods
Max HP = Efficient Max HP at the wheels... (I don't want anyone saying I made 450HP on my stock charger because its not good for your turbo or your truck and failure is just around the corner.)
1. hy35 Max HP 280-300
2. hx35 Max HP 300-320
3. hx35/40 Max HP 320-350
4. SuperB 57mm / s300/ HX40 Max HP 400-425
5. 62mm s300 Max HP 450-500
6. 64mm s300 Max HP 500-550
you can do more, but once you get to this level you should not starve your engine for air... look into a turbo upgrade that matches the power you want to produce.
his sig says he has bd tow twins and 155hp injectors. those turbos can't handle those injectors? What would be wrong with a blowoff valve? If your turbo is barking when you let off and you don't have egt issues at WFO. A bov would let the boost pressure out so the turbo doesn't bark, And to help keep everything spinning the right way one could plumb the bov back into the intake pre turbo, help spoolin between shifts as well I would imagine.
here is something cool that i have been looking into... It doesnt say that it for diesel applications, but since i first read about it in one of the diesel performance magazines i would imagine that it will work. But it is new product so i cant find much info on it.
Has anyone else heard of, or seen one of these? and will they work on large turbos making 50+ psi?
I'm curious how old your turbos are. I know of a few problems with the longevity of BD units and was hoping this isn't the case here. You need a diesel specific BOV because with no throttle blades and no vacuum it has no way of knowing when you are off the throttle. That's why the diesel BOVs are so spendy, because they require an electrical signal from the APPS to know when to dump manifold pressure. I believe the BD one has a seperate controller so you can fine tune it to your driving style. You could avoid all this by not treating the throttle like an on/off switch! And as a former owner of a six speed truck, I know this is not very easy to do!
i think it was on here that i was reading that someone said to just run a linne from the exhaust before the turbo to the bov and when i let off the throttle and drive pressure dropped then the bov would open has anyone tried this method
i would think that the waste gate would act more like a pop off valve then a blow off valve and open when you hit a predetermind amount of boost were as the blow off valve would be used for when you let off the accelerator quickly
