Bad Wastegate... Turbo Major Boost Creep and could have blown my Engine!
HTML-код
- Опубликовано: 12 авг 2019
- Today's task was figuring out my over-boosting issue and trying to determine which wastegate is sticking/stuck or malfunctioning. Tearing the wastegate apart and looking for the issue! Luckily, I have two wastegates but when it hit 39psi I could really tell the engine was making more power! It should have only made 30psi! 9psi overboost is bad, real bad in most cases....I got lucky, this time! Next video will show the data log of what boost creep looks like when this happened!!

Your content is better then a lot of people with 80 thousand subs ...crazy you don't have more followers
He should have 100 subscribers right about now he damn sure deserves it
Thanks
500k subscribers is coming I can almost guarantee. I give it 1 year.
My type guy, build it, tune it, drive it, break it and redo it, that is true racer.
John, I really appreciate all the content that you share. As a guy who is newer to boost I love having all the information that you share as it helps me with ideas and knowledge to use on my own set up. Even though we live far apart I hope to run into you at the track one day. Thanks again and good luck out there
John, loving the vids. Most people are worried about content but you give us what we want. THE REAL STUFF
I wake up and watch your videos before my cup of coffee! Thanks LS Daddy hahah keep me coming!
If it were me, I would go ahead and pull the other one now, just to be safe and take it apart and clean/lube it up.
As easy as you did the first one, it DEF wouldn't be that bad!
Sucks that a cheap part like a wastegate or solenoid can cost you so much money when they stick and blow your motor
A literal ticking time bomb.
this channel is the best thing sense sliced bread!!
I love the content and how u make it easy to understand and learn from can’t wait to see u race
Thanks
Great video John!
Thanks
you read my mind on drilling and tapping the shaft. great minds think alike, lol!
Loving this content. Glad john doc mentioned your channel. Don't tell john, but I click turbo john vids before his now.
Thanks, we are having a ball
Hey John, you make good vids, I learn a lot from your good work. I'm to old to drag race, I still have a KZ1000J2 Modified, from my younger years. I never been to the track. I be a street racer. I have not been on the bike in ten years. Not gonna get on it any time soon. I'm just gonna rebuild it and bring it to bike shows. Be safe John, and Godspeed!
Cool, good luck with the bike! Never stop!
Good call drillin and tappin that valve stem.
It's all them fiberglass fiber's sticking in your arm that's making you itch so bad! It definitely sucks... Keep the informative content! 🇺🇸🦅💪
Your videos are great!
Thanks
Very interesting content TJ
Liked/Subscribed !
Rust build on valve stem, put anti cease on the stem. Meth and heat make rust easy.
I learnt something new!
Hey John if you have anymore wastegate issues I highly recommend the Tial ones. I just don't see as many issues with Tial like I do with all the other brands and is probably why they are also used in a lot of high performance oem applications too.
That tapped screw should definitely made the year
It doesn't matter but subscribers what matters is you are the one of the best keep it up Bubba and thank you for everything that you showing us 👉👆🤟🤟
Thanks
Hey bud if I'm not mistaken there's a few different ways to avoid boost Spike by use an adjustable blow off valve as a purge valve or a eBay 40mm wastegate on the charge pipe🤓👍
I think I’ve got it fixed. I hope so anyway.
I literally lol'd at the "well shit" moment because that's exactly like what I'd do too haha
LOL, I was just moving a little to quick I guess!
I Have a couple questions ... I’m kinda new to this but what lube did you put on the back of the diaphragm and is it really necessary to apply it? Other one is ... does a bad wastegate sound like a lawnmower when u get up to boost?
You should definitely take the other one apart and install the screw from the top. I'm not a turbo guy but that just looks like a bad design from their part. I would definitely do that mod to all waste gates that you get from now on.
Lmao 😂 good Shit man!!!! You keep it real
What type of antiseize did you use. How has it held up?
Of course it’s a starter spring. Damn right we’re gonna take it apart, find the problem and reengineer it to fit our needs. Then we’re gonna put it all back together, take our junk back to the finals and probably win this time. Why? Because that’s what happens when you have more brains than money!! Dooley noted!! GOOD LUCK to you sir!!
Perfectly said!!
LOL, thanks!
HEY JOHN WHAT WASTEGATE ARE YOU USING NOW
Are you running a T4 or T6 turbine housing what's the A/R on it I guess my question is how much A/R is needed for a given fuel for example M1 vs M5
It’s s t6, 1.39 housing. There is more volume with alcohol, so a little larger housing is needed. I’ve never ran m5 but I would say it would use the same housing as m1
That's a tial diaphragm.
Will you make a video how your doors mount? TURBO JOHN!!!
I’m doing a vid on that and s few other things. Should be out in a couple days hopefully.
On the fake waste gate what if you put I real tisl diaphragm
turbo john what turbo are you using thanks and where can i buy one
This is a GTR GT55-102 from Forced Inductions! I have links in the description on the video! Check Lil John’s as well, may have some in stock!
10:42 is when i hit the subscribe button. lol
lol, I had to watch where that was.......sometimes I just get carried away
How do u keep it cooled and control the boost?
Car is on methanol, so it only water in the heads. Fan and vacuum in between rounds cools it down.
did you take the radiator set up off or relocate it
It started leaking, I cracked s fin when I was tightening it
What's the sensor on the side of the wastegate ?
Dome pressure sensor, it monitors co2 pressure for the boost controller
That's a big wastegate what do they get for those on eBay
Cheap, different styles 70-125 bucks
Lmao "LS Daddy" i died laughing in john docs video yesterday when yall said that lol yall seem to be some really good down to eaeth fellas and if you're ever in Nashville Tn and need any help at all just give me a hollar bro and if i can help any at all i will be there i have a shop, trailers, and plenty of extra Chevrolet engine parts lol we raced dirt super late models most of my life but we've been out of racing for a few years now because of my dads health problems it just didn't feel right racing without hum so i just stopped racing but I'm wanting to build a drag car now because of you guys lol i have alot of good engine parts just laying around and one complete engine left over and the engine is a 10,000 rpm circle track sbc with lots of lightweight parts it has brodix aluminum heads with titanium valves and lots of work done to them
Sounds good! John doc is s trip for sure. 10000 rpm is rowdy
Do you have a boost cut set?
I do, it’s at 40psi lol. It’s a revert to wastegate, do I don’t know how much it would bleed if only one opened. I don’t like hard ignition cuts
You don’t recon there was a small piece of aluminum trapped somewhere where the engine blew up b4 and got hung in that seat? You really haven’t heated up the engine like that until you made a pass other night. I’ve seen stranger things happen lol Question, do you have any problems spooling that big turbo up? Every time I mention getting one that big instead of two everybody starts bitching and complaining telling me I won’t be able to spool it. It would be on my 9.5 deck 438 if I don’t upgrade to the new 460ci SBF. I’d love to know how you spec out your turbo for your build, I’m kinda new to the pushrod turbo stuff, the wife’s Coyote has to 68-70 twins on it but I didn’t spec them out but I installed them and do all the tuning. I guess it would be about the same huh?
I didn’t see any debris when I pulled the gate apart, hopefully it’s good now. It usually spoils pretty good, no issues. But something has happened to the fueling map at low rpm. I’m trying to slowly lean it out, it’s way rich when I first stab the gas right now.
Turbo John well if there’s one thing I’ve learned watch you and your channel is that you’ll figure out the problem 💯 good luck dude 💯💯
What size engine your running
364
My gate siezed,and I blew my shit up 😔
I like John doc but you need to make your own hats 🧢
We created a very simple logo, hope to have a few shirts and hats in a few weeks!
Turbo John cool I’ll buy some
I have boost creep
A little boost creep (1-2psi) in not a big issue in my opinion. But if it never levels out, then there is a problem with flow (sizing) or wastegate placement
I wish you had the money to buy this C6 Vette from Mike @ StreetSpeed717 cuz he just gets a bunch of sponsors to build him a low 8 high 7 second car for next to nothing and does a bunch of stupid stuff with his cars for a while to make content for RUclips then sells the car for what it would really cost to build the car a makes a huge profit from it and he has a bunch of subscribers and views and all of his videos are stupid if you ask me I would much rather watch your channel John Doc's channel and Cleetus Mcfarland's channel cuz for one you guys build and work on your own cars and don't sell them faster than McDonald's sell fries lol and that's pretty damn fast if you ask me and I love the set up you got going on old school Gen 1 SBC "LS DADDY" to the front good luck to you on Thursday night if I was closer to Galot I would come out and hang out and watch you guys get down out there but hopefully one day soon you can get your car to the level of all them other undercover pro mods you're running up against with a carbon fiber front clip and doors and deck lid and optic armor windows or lexan windows and if it can come over the winter to where you can put that thing on a diet would be awesome atleast get it down to 2800lbs without you in it and I saw a website the other day if I come across it again I'll shoot it over to you if you want it but they sell Billet Aluminum blocks including SBC and they say that their SBC's can get up to 560cid and with a Billet block with aluminum heads rods and intake that 560cid SBC ought to be pretty light but with that many cubic inches to play with out of a fast and high revving small block with that ball bearing Jose 102mm CHOO CHOO BOI going low 4s high 3s shouldn't be a problem hell Big Chief and Murder Nova Shawn only go low 4s with them big cubic inch small blocks they got with 2 Pro Mod 88's on there but they are on big tires if they set it up to run radials I think they could get their cars to go just a little faster but anyways this is long enough Go Fast and Get Some Win Lights whether the clocks are on or not lol can't wait to see what you have in store for John Doc and did you see what he did in Maryland with Brown Sugar? LMAO now it's Broken Booger 😆
Thanks, hopefully the weather holds good for us. He is bringing the cow, which is perfect! Sucks he got the rear!
