not sure what you mean... are you saying its spinning too fast?
Surging and SRI/CAI.
Ok, so I thought I heard the turbo surging when I first did the SRI system and still thought I heard it when I did the CAI extension. My buddy drove it this past week while I was away and he heard it also.
Did Hyundai really build a turbo vehicle that reaches the surge line on the stock boost levels and tune?
Anyone else heard it? It sounds like the turbo is kinda quivering under full load at higher rpms. You probably wont hear it with the stock intake on.

Yup I think you are absolutely right Socks. Ive noticed it on mine to.
That's not good right??
How do we fix it...... this is my first Turbo car... I understand the basic of how Turbos work, but not exactly sure how surge happens and how to fix it.

No vin I don't think that's good lol BUT lucky for us socks and GT800 will fill us in on the goods (or/and bad).... =S....right socks and GT800 =D =/That's not good right??

I haven't noticed this and I don't have the FORGE BOV. I think all of you guys have this, it is possible but not likely that you guys may have attached the forge bov backwards. I'm referring to the moon crescents. Not likely but it is possible and so what's happening is most of the pressure is being shot right back to the intercooler and eventually to the turbo since its retardly set up that way. I don't honestly know tho guys, just an idea.
the forge BOV is definitely not installed backwards or it wouldn't let out any air.. The only thing that I can think of and I have no way of testing this is somehow the stock BPV/BOV setup starts venting off boost at a certain point and it doesn't with the forge. The only way to test it would be look at the boost levels on one run with the stock BPV/BOV setup and then swap to the forge with the same type of run with the same weather.
Still wouldn't quite make sense though as the turbo shouldn't be flowing anywhere near enough to be hitting the surge line. It may not actually be surge but I don't know what would cause the sound that I am hearing.
Real compressor surge (not the stuff that people talk about when their BOV doesn't open) can be a bad thing if it is really bad surge. The surge (or sound I am hearing) seems like it is very minor and hardly at the surge line.
Another reason I haven't been to concerned is typically in a surge situation the boost will fluctuate quite a bit and I haven't seen anything in the logs showing the boost spiking and dropping.

Try the $4 bov style with your intake setup and see if it still does it then, ti rule out the Forge as being involved. Then go from there..

i'd love to but chucked the stocker when I swapped to the forge. haha
There isn't really any reasoning the forge could cause it anyway. The WGA should be controlling the boost and not letting it overboost to the surge line or past it when upgrading the intake/BOV.
probably is happening stock but you aren't able to hear it with the restrictive system.

So the only way to really tell is with a Boost gauge?
And the fix would be a boost controller?

wouldn't the wastegate be controlled by the ecu?
it is however a boost controller will "trick" it to thinking it's running less boostwouldn't the wastegate be controlled by the ecu?
I dont have a Forge and im almost sure im hearing the same thing that socks is. Kinda hard to explain but ive never dealt with this style turbo before so maybe this is normal for them.
You think taking it to a shop that deals with a lot of turbos would be a good idea or do you think they would just try to sell you parts and labor? I haven't gotten my VT yet and this kind of worries me =/I dont have a Forge and im almost sure im hearing the same thing that socks is.

this sounds like the same thing i was moaning about w/ my stock VT. http://www.velosterturbo.org/forum/veloster-turbo-discussions/1075-strange-sound-turbo.html
I assume it is just being amplified since you have the CAI. If this is surging this is not good news for us VT owners. Im going to try and take a vid on my way home today and we can see if were talking about the same thing.

Mine does it too, but it really doesnt sound like surge, it sounds like the BOV is opening up at high boost to me. I think the spring needs to be a little stiffer in the stock bov. I remember back in my DSM days we would crush the stocker with a hammer so it would hold up, but I dont think I'm willing to try it here.
BTW my mods are only a sri, exhaust, and letting the stock BOV vent to atmosphere. I've looked into trying a boost controller, but this damned turbo is a pain in the ass to get to, I cant see wastegate, so I havent been able to try one out and see if it is stable.

i get this sound if i mash the gas at 3k rpm in any gear after 3rd...i dont think its surging but shrug.
My car did it tonight on my way home, I took some friends home after only letting the car warm half way. I did a full pull in the neighborhood and it felt like it was surging or lunging forward on and on like it didn't want to full boost. I did not hear any sound tho. I drove back home and I raced a mazdaspeed3 and won and there was no surging at all so idk if it wasent warm enough or.... it bugs me because its not the first time and im at 9400 on the ODO..
Mine does it also sounds like a wave. I only have a cone filter and the bvp to bov mod.
