Can't hold boost, did a boost leak test, check inside.

^Andy i know what holsets are btw, nick is just messing with me.

i think i might take this welding thing to another level.
My only issue is getting a huge spike, but not being able to hold it, i would be good with 25psi to redline, either way i got to shift early cause i can't make power up top.

Hit me up with a PM. Once I get the current car out of here, I will take a ride with you and we can check it out.

Backpressure might just be blowing the flapper open. To run and hold high boost on external wastegate cars, you often have to use the top port on the external and push boost to it, to act as a much stronger spring under boost. You can't do that on a single port internal gate, and internal gates often have weak springs. At 30psi intake side, you might have 50-60+psi of backpressure in the exhaust manifold/turbine housing, just pushing the flapper open all the way.

I know were running E85 so we can boost this high but what is the point? This turbo's peak efficiency range is like 27-28 MAX. After that it's pretty much just hot air blowing and your probably killing the life of the turbo. You can probably make more power with adding more timing and running the 26 to 28. Although I still spike to 27-28 and drop down to 24 by redline and wish I didn't there's really nothing you can do on the internal gate.

Don't worry buddy i know a little bit about running this thing, luckily i have a great FMIC, after a run, even on the dyno where my car runs hot the cold side of the FMIC is cool to the touch while the hot side you can barely hold on to.

Also, i go off of what is proven and that is the top end of the map for the E316G is a mystery, plus we have people nationally setting the bar, not including DSM god himself Curt Brown.

Also where did you come with 27-28 being the max? any proof?

I have timeslips that show my spike to 33 and settle to 22 is good for .2 faster et and 4mph. compared to last year spike to 28-29 and settle to 18-19.

Either way i got a few more tricks up my sleeve for this thing, i just wanted to know if anyone knew of anyways to hold boost, like i said the only car i have seen locally is 2g tsi when he posted his dyno sheet.
Hey dave, did you have an aftermarket intake pipe on your car? That is the only restriction that i can see right now.

Like has been said before, It seems like going with an external gate might be the best option.

I know you know what your doing, hell what do I know running around with a 15.2 afr? lol. What I stated is what I've heard over the last 3 years or so about this turbo. No hard facts, it's basically the whole reason the turbo drops off boost is cause it's not efficient enough to hold that high of boost in the upper rpm's. But like I said this is all that I've "heard" so go out and prove me wrong.

Also I believe the intake would be a pretty good restriction. Get a 3" and I'm sure you'll hold a bit more boost. Even a "street" version of a SMIM would help it out alot also.

Lol, for that price you might as well go external.

Meh, assuming you bought things new.
