- What are wastegates and blow off valves? How do they work? This is a quick video discussing wastegates and blow off valves basics! How to plumb them and why they are needed. Wastegates control boost pressure and blow off valves let the boost pressure out when you let off of the throttle.

My favorite RUclipsr!! Jus a down to earth fella tryn to show everyone how to go fast on a budget!!! A true racer!!! Like to see you build a street car!!! G body to the front!!!
This might be your most informative video ever John good job I know this is gonna help a bunch of guys out there.
Can't wait to see you guys out there having fun love the channel and I like to watch the long video I like the long ones I get to see more and sometimes learn more
Very informative, simple to understand. Thanks John. 😁👍💪💪
Cool video! Idk much about the whole turbo setup but I am learning to turbo my sbf. Thanks man.
I’m still a nitrous guy, because I don’t know enough about turbos and computer tuning to run them. This video shed some light on some things. I want to go turbo one day and let my and eat!! It’s similar to Randys motor setup, just with his old heads. Still gets down in the 460-470 range, which too bad for a nitrous small block on a working man’s budget. Lol. Love the video man
Excellent Breakdown
Awesome video TJohn! I am a retired Teamster of 30 years! I didn't know that there was that much to a turbo with wastegates!🤩🤩
Love these types of videos. Thanks. I need some help understanding C02 and zHolley HP control.
Great content! I learned some things I didn’t know.
Good video.
Thanks John 🤟🔥😁
Actually on a MAF equipped vehicle, the recirculated air goes after the MAF sensor, not before, since that air has already passed through the MAF sensor and has been calibrated for by the computer already.
Nice job bud
Hey John what’s that sound that a turbo car makes after a burnout? Just do it one more time please lol
Right on
Cool 😎 !
It will be harder on the turbo John I was with a team running that setup and it's pretty slick but you do put a little bit more wear on your turbos but I would say it's no more than ten percent more and worth it in my opinion for how sweet it makes controlling the turbos. It allows you to make peak performance out of your turbos with better control for the whole run and it's repeatable every time and that's something that's unheard of in the turbo world.
Is the additional wear and tear on the turbo due to it over spinning or from back pressure in the intake back onto the turbo?
It seems to me that smaller engines would be able to spool the turbo much quicker with the waste gate on the charge pipe, is that true?
Yeah, I have had the same question in my mind about the way Promod guys like Mark Micke are running wastegates on the intake side only. How do they keep the turbo from over spinning? Is it controlled via back pressure in the intake charge pipe back to the turbo? Will be interested to hear the information you get from Vanderhoof.
It's been really interesting what Mark and the guys at Fuel tech have done. They have said that there's always a limit to how fast a turbo can spin according to how much air the engine, and all the supporting parts can handle. As long as your running a good, proper sized turbo (not an ebay hairdrier) you shouldn't ever over spin it. It's kinda like the cheap dollar store pin wheel. It only spins as hard as you can blow on it. At some point, a motor runs out of "blow". It's really no different that having your waste gates pinned shut at wide open throttle.
Will using wastegates on the turbo discharge pipe cause the turbo to push oil pass the turbo seals? Everytime I see a diesel blow off a turbo hose it push oil pass the turbo oil seals
Well said John....a 2d hole is a 3d sphere 🍺
You're a good teacher John! Now go show us how it works on the track! Throw some TurboJohn Gaptizing on their ass! 😂
John diesel engines don't have throttle plates No butterflies therefore they can not search
They surge when you are on the left side of the compressor map.
@@TurboJohnRacing in your case it's either a bad wastegate that's a 7.3 or is there a variable vein in back of the turbine wheel that stuck because of the carbon which is what controls the Boost that's why you don't see a wastegate
That’s not serge it’s lugging the motor you need to down shift from OD to D and possibly 2nd
On a stock 7.3, it 100 percent is turbo surge. There used to be some RUclips vids where you could hear it.
Dang hair dryers…
I feel like you skipped a bunch of information. Maybe I’m just stupid
