hmmm mine had a m16x1.5 not m12x1.5 maybe different holsets had different thread pitchs? i have an 8-blade hx35. anyways i couldnt find anything that was m16x1.5 to 3an so i had to use two fittings(first setup was 3 fittings as i had to use a -4an to -4an 90* fitting for fitment)

i have yet to se a hx35 that didnt have 12x1.50 unless you didnt take the factory fitting off yet
does yours have that nut looking deal on top or no?

 

yes it has a factory fitting on it

when i got the turbo i did tons of searching to find info on it...i remembering it being a pain in the *** to track down info. found most of my answers on dsm websites....for some reason this thread never popped up in my searches

 

take that nut deal off and its a 12x1.50

 

I'm running a -4 with a restrictor to my hx35 and I have no problems with oiling at all. Haven't blown oil and I have about a year on it now. And I'm running 25+ lbs if boost on it daily.

 

So. A lot of people have said that it you want to remove the silencer on the compressor intake of an he351ve then just grind down those 3 pins and it pops off.

Those people are wrong




On the VE (and possibly the he351 as well the pins hold the whole inner portion of the housing in place. Although this makes my idea for pre-turbo meth injectoon

 

I have a really cool and simple idea to control the vgt system on an he351ve without using a motor.

I'll post pics and a video here soon.

 

something like this?

 

Nope, a system like that doesn't offer precise control

My idea uses a dual port internal wastegate assembly as well as a very small liner actuator to open the housing/vane under cruising conditions, when throttle or load reaches a preset limit the ecu retracts the actuator, shutting the vanes (with the help of a return spring) and then through the use of a boost controller, the wastegate actuator opens the at a predetermined rate.

Actually if I can refine the system enough I could just use the return spring and the electric actuator to have precise control

 

Finally got the video made, uploading now

 

 

He351ve blowing into a sc14 supercharger all mounted on my D16 vitara setup.

 

Yay video, its in 1080p and I tried to keep it short, kept getting phone calls so it took 8 takes, no editing so be kind lol

 

says video is private

 

Sorry fixed.

I think the idea is solid, especially after some real world testing.

 

Cool man. Yeah I think your controller for the actuator could handle it all really as you said. The WG actuator is just going to be reading map basically, which is one of the things your controller would be handling as well I am assuming... either AEM or separate pwm out microcontroller.

 

The AEM has a pwm for the IAC and I think one other user designated,

I'm not using an iacv so I might be able to do it with that output, not sure until I start looking at the outputs

I wanted to use the internal actuator at first just to verify the system works, then I'll start dialing back the wastegate and see what the electric actuator can do.

I have to run down to the BMW bike place my friend works at and get the diagram for the actuator and see what kind of signal the ecu sends it.

Because if I can remove the OEM geared piece and replace it with something that can capture the end of the actuator (it has a few grooves) then even a return spring won't be needed, unless back pressure gets high enough to move the vane, then I'll need a helper spring of some sort

I think I'm onto a solid idea, just need to test it all. Still cleaning up from moving since the movers just threw **** everywhere

Plus with the ecu looking at turbine shaft speed, exhaust manifold back pressure and engine load/rpm I think I can map out a solid control system that can be adaptable to any boost levels.

 

sounds like a very well thought out plan, i see no reason why it wouldnt work, hopefully it works as planned then you could make kits and sell them haaha

 

I might be able to make the kits, but tuning would be up to the end user.. and lije I said first in the video, I don't think a chipped p2w could handle it, due to the varying nature of the required inputs (especially the hall effect shaft speed sensor) would require a standalone ECU

And it wouldn't be cheap, the actuator from BMW is 150 by itself. Maybe I can find another cheaper one but I don't know if it would be compact as the BMW ones.

I'm thinking about making the mounting bracket cover the whole area where the controller was, top to bottom and I'll incorporate a crossover tube to allow coolant to flow through the chra, or offer an option for just a flat plate if you don't want to run coolant

I could do the plate in a variety of colors and finishes, anodized or powder coated.

Might be laser/plasma/water cut material, maybe offer an aluminum mounting plate or a slightly cheaper mild steel plate.

It's all still in the bench testing phases though, I need to get a plug in engine simulator for my AEM ems so I can see if it all works (donations accepted :p)

 

Did you get anymore info on this? I maybe picking up one up as well! And where would be a good place to shop t3 exhaust housings with Vband?

 

EBay is about it

 

Yea i figured that..... Im picking up a brand new one for a steal..... but im nowhere near maxing out my setup at the moment, i just figured that if he takes what im gonna give then i might as well jump on it lol

they do holset stuff

 

The concept is very nice.I still didnt undertand how the "partial opening" will happen.That electric mechanism that will open close, can be controled to partialy push?The idea is definetly promising.

 

I like the twincharge setup.Did you test it ?
