6.7, Holset HE351VGT turbo

[KLauber]

hey if ur willin to sell it, u might have a taker here. i had the idea not 2 months ago, and then i just read ur thread. the he351 seems to be the perfect solution to us guys that arent pushin any real power levels, yet. did you say you did get a double action waste gate?

i am currently using a he351cw mon vgt version on my 96, it mounts right to the the manifold and uses a hx40 downpipe. the turbo has to be reclocked and it works great, but surges at 20+psi when i let off the throttle fast. peak boost between 42 and 45psi and keeps egt's cooler than the hx35. i know its not the vgt but it works good.



i have heard of people using the he351cw or hx35 wastegate actuator modified to actuate the vanes using a set of stop screws to limit travel and control surge.

it is more then likely going on my 635 bmw. i could never find a double acting wastegate, the final control system i figured up was a wastegate to open and a linear actuator to run the e-brake direction, with a possibility of running the whole thing off the actuator, i found a place with a $70 controller that has 3 positions at the push of a button, one for the brake and run the other two off pressure switches to advance the rack in steps

I have the turbo but the moving the vanes has me im set on using a wastegate accuator just not sure how to get the brake to work with it. Help Please.

I am very interested in what you guys are talking about here a friend has just recently bought a VGT off a 08 and we are working on getting it set up to put on his 2000 5sp. we are planning on trying to control the vanes with a waste gate actuator that is set to open clear up at like 8lbs of boost and then we are going to try to use an electronic ram to slotted to the VGT actuator to control the E brake control. would like any thoughts regarding this idea?

this is what i came up with before i aborted the project
#ad


i was going to use a low pressure wastegate of around 5# opening pressure and trim the opening point with a bleed valve, the other side labeled actuator i was going to use some sort of linear actuator (on the other side of a seesaw linkage), either pressure, vacuum or electric, the opposing not in action servo would act as the pivot for the acting servo to move the rack arm, tweak it to a nice starting position at rest and then tune the servos to move it to the desired end point

its not a perfect solution but it is the concept i came up with, i never got as far as prototype so it likely has bugs, the last actuator i came up with was electric and run by a stand alone controller that you can set the end points and have 3 different preset positions, it was about $150 and i had started thinking about running the whole thing via a single more advanced actuator/controller with more preset position capability and have the thing advance the rack as pressure sensors would be tripped by rising boost
