AJPTurbo boost regulator mod with EcoPowerParts charge pipes

ok guys, seems to be working now. it is starting to leak at 28.3psi including atmosphere pressure. needs fine tuned, but i have a good feeling about this.
here is a log to peek at. couldnt do a full ajp log,too much traffic.
 
Looking pretty good f8tlSHO!

I got a log this weekend of my car, in warmer weather, so I thought I would share. Fuel pressure looks better, so I think I will be able to go up a spring for the drag track, once I get a time on the current setup.

 
here is a log with 3 pulls on it. the first pull had a spike of about 232kpa ,i opened the mbc a little,the last 2 look pretty steady right around 200kpa. the gate opened in between shifts and faded back to closed. i am no expert looking at logs,anyone see anything funky?
 
i have a quick question... i understand why you guys are using a waste gate to regulate, does that mean that the stock waste gates do not function properly in order to keep fuel spikes and irregularboost levels or is it juat not a tunable with only the stock qaste gates... all i know is that i cant stand when the throttle blade closes during a pull.  like a brick wall.

Stock gates work exactly as designed. The regulator mod (added wastegate) only functions to keep boost from spiking on shifts, and allowing for the throttle to stay open. It actually keeps fuel pressure in check better than the OE system with throttle closing does IMO.
 
^What derf said. This mod does not affect the function of the OE wastegates.

This mod is adding an additional wastegate in a non-traditional function (intake tract rather than exhaust).

This allows the throttle blade to stay fully open, and when the TIP spikes during a shift, the extra pressure bleeds out of the intake wastegate rather than being forced into the intake (or closing the throttle blade, as is done to control boost spikes without the mod).

In this application, the intake wastegate functions more or less, kinda-sorta like a BOV (but not quite, lol)

Think this would work for the wastegate flange to weld to noisemaker eliminator pipe? Tial makes an actual 38mm aluminum flange kit says 38mm,

It may work, and I don't recall if that was available when I did mine a while back. However, the gasket for the Vband ma cause some issue, and you would need to verify that the two sides of the vband flange will be compatable, as not all vband flanges are milled to the same specs. I would call TiAL and ask, as when I did so, I was told they had nothing that would mate.
 
I emailed them, I can't seem to find their phone number. THe website contact info only shows a fax number and it just whistles at me when I call. I whistled back but I think it cursed me out.
 
LOL, need to practice that whistle i guess!  Will see if a phone no exists.

OK may have found a solution for a mount, working on it. :)

hope your solution doesn't involve TiAL, they just got back to me:

"Hello,

Being it is a wastegate and not a bypass valve, we do not make a alum flange for this unit, nor will the QRJ flange work.  You would have to mimic the flange in the box on a lathe or find someone that makes it, which there are a few out there that do.

Best Regards"
 
Happen to be near me at all? I'm in southeastern PA :|  Looking to get at least the tial setup next and I just had downpiipes put on and was looking at those cutout mods. What do you think of that cutout you have, looks nice?

What did each of those cost?

I live in southeastern Massachusetts. I love the exhaust cutout although very expensive approximately $2000. The wastegate mod was around $650 complete with the gate and repowdercoating the pipe

Someone told me they ran the wastegate mod and car was running hotter vs the throttle control method. Do you find that with yours?

That was me... and yes, I have datalogs to prove it.  It's a great modification but my turbos did run hotter. First through second gear was not bad as the wastegate mod didn't open much... third gear with no throttle control the wastegate opens longer which causes the turbos to work harder to keep the boost..

I didn't poo poo the modification. I loved it when I ran it, but I believe personally using the throttle works better on this car to control the boost spikes.

Again... this is just my opinion on my car... others run it and like it..

There are dynos of those with and without the modification... they are identical in curve and output... so why stress the turbos for little to no gain?

Keeping the throttle open does make the car much more responsive.
