It's great to see the real-life methods of turbo system design, including the alternatives to theory that may work well in specific setups. Showing this wide range of design choices is pretty sharp.
I've wondered about how I should plumb my wastegate; this helped a bunch! That gate built into the turbine housing...I'm gonna have to think about that one. I recognize that functionally it's not significantly different from an internal gate, but I gotta wrap my head around it. And as another commenter said, that has to be the most casual 930 whp ever, snuck up on a few psi at a time. He didn't like the wagon, but I think it's cool! A Grampa car, but with mods...I love it! No cool kid from high school would ever suspect.
I learn a lot every time I view your videos. Good work would love to see you build from start to finish a GMC envoy with a 4.2 vortec turbo system. Please
I had a single 38mm wastegate on my stock 5.0 Mustang off the passenger side merge pipe and did fine with the large frame T4 Freightliner turbo but with the 96mm T6 it was like detouring a river with a straw....hopeless lol.
3:30 that's the thing though... Loads of people do run 90 degree wastegate setups like that and it works fine. There's plenty of very experienced and successful manifold builders that are doing it with a wastegate coming off at 90 degrees. Maybe it becomes an issue at really high boost levels but for most of us running less than 2 bar of boost its really a non issue
where did the 3~4% turbine efficiency loss number come from ? (trying to learn. gate on the turbine is common in the bmw i6 world. ) also, that Camero? it's twin scroll but the manifold is built so banks aren't divided so the pulses are not separated ?
@@drewdavis239 Thanks. Ok. Gotcha. That one actually is plumbed with each bank going into each portion of the divided turbine. We used one of these. www.ebay.com/itm/154797660840?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=j763U9XpSne&sssrc=2349624&ssuid=egm6iVD_T8e&var=&widget_ver=artemis&media=COPY
I have not had any trouble with that in the past. The one setup I showed was similar to what you are describing, and has a lot.of street miles on it with no issues.
Getting close on my project for injectors. What injectors are you using ? And are decapped ones worth the trouble probably gonna start with 8-10 lbs boost. But that probably won't last long . Thanks
I normally use decapped injectors for lower lower horsepower stuff. They work great. For medium to high horsepower stuff we've have great success with Snake Eater Performance injectors.
@@Calvin-Nelson yup, that’s why I went to drive by wire on top of my blower, so I could change the throttle opening rate, big block Chevy blower motors and five speeds don’t launch well under full power
100% love the real world technical stuff people can learn from mistakes
And bad mistakes... I've made a few... Lol
@@Calvin-Nelson we all have that's how good people learn 😉🦘
@@Calvin-Nelson What you did there. I see it.
Great, educational video Calvin. It is a good way to teach young/ inexperienced fabricators why you should or shouldn't do certain things
That is the most casual 930whp I've ever seen
Leave the gate in the truck and just cap it-all da boost
lol lets see this on your channel wastegate delete dyno test. #therealbigbang!!!
Moon tune!

Great video again calvin!!
Learning and seeing it in your hands and in action on the car is great. You explain things very well. The wagon tho... mmmm
These info vids are getting good !!!!!!
Put it on the turbo exhaust housing, you don't want to disturb the exhaust flow in the manifold
always educational .. love the vids! keep it up
mate that was extremely informative, I learned a heap. Thanks
I learn a lot every time I view your videos. Good work would love to see you build from start to finish a GMC envoy with a 4.2 vortec turbo system. Please
Great information!
Where in pa are u guys here for work wasn't sure if there was any dragstrip stuff going on

Thank you sir. Can you explain about Blow off valve? Its need special location like this or not?
It's not as critical, but I try to run it closer to the throttle body.
@@Calvin-Nelson thank you very much sir. appreciate it🤜🤛
Well explained.

If it works for you, that's great. I'm just trying to help people that are starting from scratch.
That 25 psi run sounds scary!

The percentage came from my friend who is a compressor engineer.
Not sure what Camaro you are talking about. Maybe you could provide a time stamp.
5:15 thanks for the fast reply. crazy how many big RUclips channels comment on your videos .. says a lot about this channel

How many cars you got now?? 😄🏁🏁
A lot
Will I overheat a waste gates placing it closer to the engine than the turbo? Say half way in between for a compact package

Loved the vid Kev!

Should be in a bend from what I've read .. but I guess I'll find out in this video 😅
you mean "Where", not how?
"We got away with it i dont know why" because it doesnt really matter lol
I don't know about you, but I like to maximize my chances of success, but I'm not going to tell you how to live your life. Have a good one!
Boost control is easy, just change your blower pulley! 😹
That's really hard to do going down the track. Lol
@@Calvin-Nelson yup, that’s why I went to drive by wire on top of my blower, so I could change the throttle opening rate, big block Chevy blower motors and five speeds don’t launch well under full power
The losses by having the waste gate on the turbine you won't even notice. Shit f1 had that in the late 70s.
