    What's this??

    Welcome to the world of leaking turbos lol. Sucks to hear and Im right there with you on blown HGs Ive already replaced them once in the last year due to boost and now there slowly showing signs again. Not to mention my MAF crapped out so I cant get on it hard unti lI can get to the yard to...

    What's this??

    When you close the throttle you lose the energy that spins the turbine so the wastegate isnt going to help you there only the bov because inertia keeps the compressor spinning. Also some guys do use bovs as bypasses at idle. The vaccum from a closed throttle keeps the bypass open alowing air to...

    What's this??

    some people have had problems with recirculation and some havent. I have my bov dumped to atmoshpere after the maf with no issues. this is mostly because I have my bov adjusted to only open to purge during throttle cut. You can adjust bovs so they stay open during vaccum (idle) and this would...

    The bov looks great so how long until the turbo spins?

    What's this??

    If you couple the turbo where the cat use to be lag will not be an issue. the more lenght of pipe before the turbine the more the exhaust has lost heat=lower velocity gases that have contacted as they lose heat. Turbos love heat. With out heat and cylinder pressure (load) you will not spool the...

    cmon load the motor up I want to hear it spool

    looks great get it started. Do you have a wideband to monitor the AFRs?

    i need some advice on my exploder

    are you 100% positive there rubbing on the sway bars? You may have different back spacing but My 31s only rub on the splash shields near the firewall and that an easy fix that I just havent finished yet

    Still having problems....

    the ticking can also been worn pushrods which are known to wear out quickly

    Actually rear mount turbos do spool slower on the street depending on the setup. Ive had a rear mounted TT v8 setup I dont like how a rear mount spools up on the street. Not to mention relying on a noisy scavenge pump. The only reason they spool as fast as the ydo Is becasue rear mounts generall...

    Turbo Charged 4.0L BII Build

    it can help but also wit hthe bigger volume and restriction of the intercooler the response time is slower. But yes it will always air that is blown by densifying the air cahrge which means more air molecules per volume. its a balancing act. if your only pushing 5 psi of boost and depending on...

    Turbo Charged 4.0L BII Build

    An intercooler, or charge air cooler, is an air-to-air or air-to-liquid heat exchange device used on turbocharged and supercharged (forced induction) internal combustion engines to improve their volumetric efficiency by increasing intake air charge density through isochoric cooling. A decrease...

    It dosent add air the air is denser. Coolar air =denser air. The collder the Air charge more power can be built from the same amount of pressure. it often depends on the compressor/turbocharger design on how much the compressing will heat the air charge. On cold days my 4.0 comsumin 5 psi is...

    Turbo Charged 4.0L BII Build

    depending on the setup you IATs woulnt be that high on only 5 psi. This is why a intercooler isnt truly necesary. The other issue is a intercooler will slow response depending on how restrictive the intercooler is (theres many different designs. cooler air does=denser air. It all depends on how...

    Turbo Charged 4.0L BII Build

    You can used crush bent pipe for a turbo setup. mandrel bent is just better. most shops use compression benders anyways. Very few shops run mandrel benders as the bender itself costs $$$$$$$$$$$$$. Velocity will just be down. All my pipe was dug (with permission from owner) out of an exhaust...

    Both oem manifolds are flipped and the hotside runs in front of the radiator as you can see in this video I haven't dyno'd it yet. The ecu is completely stock and the only fuel system adjustment so far is 30# injectors. After i get the new heads installed "someday" I plan to convert to...
