tial wastegate for charge piping

[ajpturbo]

this is a great idea ajp!
i have an atr bov im going to modify for this
didnt even know i could use it!

I don't know if you can...Nobody has done it....Me thinks it's not the best way...I'm not sure why you would want to....It's completely backwards to try and adapt a device that's meant to hold boost under load and bleed pressure under vacuum.

A wastegate is meant to bleed boost or pressure under load

AJP is right. I thought a BOV was more or less just a device to release pressure on the intake side(to prevent compressor surge) vs a wastegate on the exhaust side to control turbo speed . . but after further reading it wouldn't work in this application since it gets sucked open instead of pushed open like a wastegate. My bad for introducing any confusion here. There's a company local to me that makes very affordable and good quality BOV's so i was just exploring it as an option vs a $250 wastegate.

$250 for the wastegate and then $35 or so to have the vband adapter welded to a dump pipe that needs to be bent in the correct position. It's not a cheap modification but well worth it if you are tuned by AJPTURBO.. running 0-60 all day @ 4.3second without break launching...

Well worth it considering it costs same or less than a CAI!

Yeah and i can see data improvements ....not so much with the cai

Yea. Bradley was originally using the throttle blade to control the boost spikes.. same tune but with this WG mod to control the spikes made a HUGE difference... Night and day... If it was between a CAI/Exhaust or this mod... I would take this mod..

i reread it -i get it-in addition to the factory gate

^good to hear some feedback from someone who's performed the mod and felt the improvement. this will definitely be in the future plans for me, just can't swing the cash right now. however. . a sub $300 mod that helps control boost spike and provides ANY performance improvement is a damn good value IMO. vendors!!

I would highly recommend talking to AJPTurbo about having him tune you for this mod if he is taking customer's right now. There are some tuning adjustments that need to be addressed. He goes into some of it in the beginning of this thread.

It really helps because with this mod and AJPTurbos tune the boost is almost a flat line across... So there are no wild dips or jumps in boost so it just pulls through all the gears. And since you don't fight the big boost spikes at shifts your fuel pressure stays nice and strong.

Oh...and you get a really cool blow off valve sound when you step on it... And then if you are VTA those woosh too when you let off.. I have gotten some weird looks from the Subaru guys when they catch up at the next light...

hahaha that's golden! and yes adjustments will be made with the tune when I do it

So if I understand correctly you can't use the waste gate with out blow off valves because if the throttle closes before you have enough enough boost to open the waste gate it will trap the boost.

Why would you not have blow off valves?.....this is a simple device added to the charge piping to allow the system to bleed off excess boost at wot only....has nothing to do with part throttle and lift off conditions....car operates as it should except will it makes it so the ecu doesnt use throttle blade to regulate boost

I could build a mount into my hot pipes as an option

Any movement on this option? I am getting ready to replace my plastic with aluminum pipes, painted to look nice under the hood.  I would like to get on board with this waste gate setup.

None, you'd have to order them uncoated and then have someone weld a tube so you can do what AJP did with a rubber hose.

Maybe I'm misunderstanding what the issue was getting a prototype done, but...  wouldn't you just need aluminum pipe of the same ID as the wastegate Vband flange ID, then weld that pipe to the "noisemaker eliminator pipe" on one end, and an aluminum vband flange on the other end(something like this? http://www.jegs.com/i/TiAL-Sport/768/004809/10002/-1)

Just curious because I want to do hotpipes down the road, and I know this wastegate mod is something I will want to do as well, since boost spikes are creating headaches for me.

Could I use these parts to craft this for my car since there are no other options available yet?

I'd have to cut my intake hope to splice the t-pipe in, but it *shouls* work, shouldn't it? The 2.5" t-pipe is just for an example. I have to go measure the hose to make sure that's the right size.

I wouldn't use that wastegate on the turbo, but it should be fine in this application, right? Other than not being able to build boost, I can't imagine anything catastrophic happening even if the cheap WG fails. Also, since that WG only comes with 2 springs, can I use a boost controller to fine tune it?

Obviously this has to wait until SCT decides I'm allowed to get a tune...

AJP, I have a Tial MV-S on order (and SHO intake tubing with the noisemaker junction) to plumb in to my XPL0DR for the 91 tune.

Just out of curiosity, do you recommend any sort of periodic maintenance for the Tial as far as lubrication and or spring changes? I presume in this low heat application, that it will have better longevity.

Since one side of the waste gate is open inside the engine compartment, would you advise some sort of filter to cover the outlet port and protect against contamination or is that overkill?

Documentation is lacking on the Tial website, so I figured I'd check with the "patent holder" of this boost regulator.

 

[ajpturbo]

I think they are pretty robust...And since wastegates are typically used on the exhaust they are designed for hot temps....so it being on the charge piping and will only see temps of 150 or less and compared to 1000 degrees id expect it to last a lifetime

I expected to see some residue near the outlet but I didn't on mine...but it really isnt open that often...basically wot upshifts for a second or so

 

[StealBlueSHO]

I have no residue on mine either... Very clean, looks as good as the day I bought it...

Cool, thanks guys. One other quick installation question. I was looking at AJP's pictures at the beginning of the thread as well as the pics in StealBlueSho's FS thread, and I was trying to figure out if you guys actually secured the wastegate to anything.

It looks like it's just kind of laying on top of the A/C lines. On my Explorer, it appears that the A/C lines are fixed and the engine may have some movement relative to them, so I wasn't too keen on just letting it lay there in open space.

I was trying to find a way to locate the wg more securely, but plumbing looks like it might get complex.
