Also you can leave the hole size and grind the inside housing for better flow out the hole. Most IWG housings have room for porting inside. I mostly leave the hole size alone cause porting that usually causes leaking issues. just a tip for anyone reading comments
If you have a divorced downpipe make sure the splitter clears the wastegate and doesnt rub. Sometimes the splitter gets in the way and wont let the wastegate fully open
A less free-flowing intake track and/or exhaust will also stop creep, but it'll kill power too. My hybrid GT2871 (Garrett 2871 compressor/housing w/ ported stock hotside) didn't creep at all at first. Then, I finished out my full 3" exhaust and started to creep up to ~25psi in the winter on 93 octane (I'm tuned to ~22.psi). No biggie. I run water-methanol, so I have plenty of fueling and knock protection. I also have overboost protection that'll open my BPV at ~26.5psi. My ethanol tune is setup for ~25psi anyways, so it's not really that big of a deal.
The turbine housing sealing surface for the waste gate valve on my K03 turbo cracked in three places. The car is tuned for 5 PSI higher boost than factory. I had to buy a new one piece exhaust manifold/turbine housing. Is it possible to have a machine shop install something like a hardened exhaust valve seat in the sealing surface under the waste gate valve to prevent this failure in the future?
It’s beneficial to also port the inside of the housing to get smoother exhaust flow to the wastegate, correct? And i assume porting the turbine exit doesn’t really do anything
I’m tuned to 26psi and sometimes I get between 19-26. Never lower than 19 or higher than 26. Just random boost levels between those digits. Could it be the wastegate or the flapper not closing or opening when needed???
I have a stock pt cruiser gt... and it start creeping at wot... it flutters ... its the wastagate actuator? I checked for boost leaks and the stock diverter is keaking a lot... could it be that? Thank you
Question I have a 38mm manifold but a 39mm wastegate...will that makes boost creep? I am having the issue of it over boosting way passed the 6 psi spring and boost controller setting...I have a 6 psi spring but it boost to 15 or 16
I’m having an issue where I’ll be idling at about -9 to -10 and it’ll randomly start reading positive numbers and a small blip of my throttle puts it back down. A small pull built up to 3 pounds and then flashed 22 pounds, resulting in the car dying and an overboost code. Could a faulty wastegate be my problem?
I mod a flange to exhaust housing become divorce downpipe and vent to atmosphere, but it's become boost creep, is it the flange i mod has block the valve flap ? So the flap can't open fully when i full throttle, exhaust can't escape fully, become overboost 1.5 bar
Does the nipple helps not to over boost..i have a gt2860rs but dont have that nipple..so my wastegate actuator nipple goes to the vsv vacuum line and T it to go to the bov..byt i do have boost spike i have a 7 psi internal wastegate and after 6k it jumps to 14 psi.. dont know what to do
Hey mate, very good video +1 sub! I know I could go to a forum with this question but a lot gets lots in translation and its late down here in Australia haha. Just today my car RB25DET starting getting some major boost creep. It has a turbo back exhaust and an internally gated turbo. The car has never given me grief before its only been these last days that I've pushed her a fair bit and i think this is why. Even when taking off at say 3k rpm it has been skidding, which is confusing me beyond anything. Could this be a result of a faulty line that inhibits the wastegate from opening? I think its had a little bit of creep before but never this bad so I'm not sure its a porting issue where not enough exhaust is escaping. Anyway let me know what you think it could possible be, cheers!
+Mah Oney when you reduce the back pressure by adding a less restrictive exhaust, the turbo will creep if the wastegate does not flow well enough, but you would never have a creep issue until reducing the back pressure after the turbo
Nice Video man … I have a problem with my boost , it spikes up to 18 PSI on a stock turbo. Not sure to go with replacing the EBC or the IWG actuator. Any suggestions ?
When does it spike up ? Only in CD weather? Give engine spec and turbo special and wastegate setup.. too many variables to just guess best suggestions to your problem.
now that I see this video I think this might be the problem. sometimes my mini cooper does not make full boost even in full throttle, sometimes stops making boost and there sometimes that it doesn't build boost at all and it lags a lot.
+Willie Lemosse I would start off with a boost leak test. If yours has the issue with the wastegate you can get mic turbo the fix it. I'm still trying to figure out how the bushing comes out on the Mini Cooper, I think it's welded in. I'm getting new turbine housing for the mini machined for the larger shafts but I won't get them for another 45 days
+Turbo Lab America im going to start with a boost leak check to see if that's the issue if not im going to send you video and pictures throught an email for you to see it.
I mate I got a 05 bf series ford falcon xr6 turbo with the gt3540 turbo when I get up to high rpm I. The high boost range my car cuts off then back on after a second or 2 I pulled a code for wast gait failure what should I use to fix or get the wast gate flapper working correctly or would it be the boost solinoid I was told to spray wd40 or brake cleaner down the boost solinoid inlets that it generally fixes it when it gets dirty ext ext let me know what you think thanks
+Turbo Lab America I installed 66 turbine i got from you guys. It doesn't spin freely like the original one. We swapped it back to the original and it spins freely. Wondering if I'm doing something wrong. Please help
Good way to blow your engine. BOV doesn’t have pressure controls. The BOV is a release of intake air pressure on the other side of the block. The wastegate is a smarter BOV for your exhaust gases.
@@GriogharThomasBaldwin hmm. i am not convinced. as i see it, the only negative difference is that a blocked wastegate will force the turbo to follow exhaust speed, but that does not matter much. of course the pressure will go up on the turbine side, but that must be a matter of matching the turbo to the engine. no lack and no creep, will be a big benefit. i guess it is a matter of careful matching of the turbo to the engine. in that way you get all the benefits - without blowing your engine. it is only if your engine cannot take the max pressure the turbo can deliver at typical around 6000rpms, that the engine will be forced beyound what it can take. if you match the 2 components, you will get an encredible experience. in this way the wastegate and bov is only a compensation for poor matching.

If your raising boost pressure over stock you build a custom dump pipe or turbo back exhaust system you don't necessarily have to port the wastegate.

Do EFR turbos exhibit the boost creep problem you spoke about or were their internal wastegates engineered to not do this?
What's an EFR Turbo? Yes possibly if there is extra material around WG port in cold weather. It can happen. Not all turbos ate created equal
Austin, I'm bout to put that HX40 you guys machined a hotside for on my KA-T.
ka for lyfe bro

okay thanks for the response. I am 90% sure it's a wastegate issue. Thankyou

If stock you don't need external WG.

true story,. I set boost at 10 psi and got spikes of 14, ported the wastegate and it would only boost to 5psi. Too much pressure on the flapper.
Couldn't you fix this with an electronic boost controller?

Sounds like you hitting a E-Fuel cut. Check ECU parameters and range during operation.

@@Mr94civicEX did he help?
i know this is not precisely the topic. but why not just block the wastegate and regulate everything through the bov?
Good way to blow your engine. BOV doesn’t have pressure controls. The BOV is a release of intake air pressure on the other side of the block. The wastegate is a smarter BOV for your exhaust gases.
