EBC on internal wastegate?

confUsed · Post by **confUsed** » Fri Aug 01, 2008 8:09 am

Anyone tried running the ebc in ectune on an internally gated setup? I dont have any experience with ebc's, so I dont even know if its possible. But if it might work it would be fun to try

Yeah it works.

yup, done it here too, I actually took a guys profec B off, and used the selenoid ..

OK, thanks! I'll soon have a new toy to play with

can someone post a quick diagram (in ms paint) or even a picture of how they actually routed the vaccuum lines to the EBC solenoid to the internal wastegate nipple?>

put the WG inline, between the WG and turbo... so it bleeds off pressure to air when EBC is doing it's adjustment...

its simple if you take the solenoid and run the vacuum lines from the #2 port to the wastegate actuator and then the #3 to the pressure side or the turbine and filter the #1 then run your ground and then your power to the ecu. Thats it. Good Luck.[/img]

doesnt that effectively create a boost leak?

you can either bleed off or block pressure going to the wg

I think it would be set up as a normally open solenoid (fails to low boost), and 100% DC would be unlimited (full) boost. You wouldn't 'leak' any move CFM's of air through the vent than you would with a normal extranal WG; you'd plug the solenoid's vent since [most] stock actuators slowly bleed off boost all by themselves. Just be aware that the max 'multiplier' over spring pressure won't be as high as being able to pressurize the other side of the WG [external setup]. You could rig it to be dual-ported, but a typical single-port actuator leaks BADLY around the bottom shaft seal. You can get aftermarket actuators that are dual-ported, and seal around the bottom shaft. You would be able to run more boost with the actuator in that case vs just a single port setup.

i did a lot of research on wastegate etc etc.. esp now with the synapse i have... wastegate either internal or external require x amount of pressure to open. this is determent by the spring. the spring will allow a x mm lift per psi.. the psi comes from 2 places... bottom port and manifold(backpressure). synapse has the option to adjust initial valve lift too... on some wg the gate starts to open as soon as it see a few psi due to back pressure.. synapse you can adjust when it starts to open. i'm testing 2 thing shortly... bleeding the bottom port and adding it to the top port. 100% dc will give no boost source to bottom port and 100% boost on top port... and CO2 boost controller

Calvin I've seen some 4-way solenoid valves that could make the 'bleeding' type work, or so I think. It would basicly cycle between pressurizing the top and bottom ports, rather than just adding boost to the top. Most 4-port 4-ways will have one 'input' inlet on the front, the 2nd will be the vent. It will basicly swap the routes between the two outputs. You could then do 100% with the top at boost pressure & bottom at atmosphere pressure, and 0% would be the opposite. I would imagine that you would only have to rewrite some of the input titles to make either work. It would only need different values based on what you want to use, since 100% DC with CO2 could give you far more boost than 100% DC with a normal 3-way boost solenoid.

drop me a mail to discuss this.. what i did now with ectune solenoid is bleed to bottom port to top port... 100% dc is full press on top port and atmosphere pressure on bottom port. Not sure how 4 way work... drop me a mail... i'll try co2 shortly... low boost(low spring) high boost... but is for race application only

I think this is similar to the idea in my other thread. The only issue would be releaving the pressure between each cycle/valve movement. I'll send you some pictures I'm thinking of sometime this week, since school has me nailed to the wall till friday. As for the 4-way, most will work by supplying the boost pressure to one outlet, while venting the other; of course, which gets vented is based on the valve being open or closed. I'm sure a 3-way could work fine, except not as cleanly (extra parts?). I'll have to look into that. I think if you got a co2 system working, you'd have a real winner. It seems more and more common for people to put S36x borg-warner turbos on street cars and run 30+ psi at the track.

i guess so
