I know this video is 2 years old already but roughly the same time I had an idea of making a sleeper exhaust so it looks like it is 1 exhaust but both exhaust manifolds are kept separate through out the whole exhaust system and having twin tail pipes
@fahler speed and performance, are you selling these to the public or was it a one time thing? I’d like to see how much one with a T4 flange would cost.
one time thing. This was an incredible amount of labor, I'm not sure small benefits would warrant the cost when compared to one of our "standard" headers
That's dope but that far back cylinder port merge scares me and should have been bent more and the entry moved forward to smooth the flow imo cause of how tight it is back there and how abrupt the turn is
the template didnt fit right because your drawing was from two flat circles. drawing a plane between the two created a oval shaped pipe. couple different ways to draw it round, but it still ended up close enough. would be a bit more critical if it were thin wall
Nice job Joey!! Have you and Matt done any testing on this? I was thinking this would allow a more accurate reading for trying closed loop with a 02 bung for passenger side. Just a thought
Thanks. We did not do much testing other than Butt Dyno. Matt thought it felt more punchy down low. You may be right on the 02 readings, but most sensors dont survive long under the high heat and pressure of pre-turbo exhaust in my experience.
We never got any official data. But matt did say he felt it spooled significantly faster than his old set up. I would like to think his butt is calibrated fairly well.
Exactly, Only really beneficial on a v8 if you’re running twin turbos and all 4 of the runners on each side are the same length and paired together at the collector based on firing order.
Looks like I am going to have to build something similar for my Ford truck. How do you come up with your saddle joints? I would like to not do that the hard way. I need to go 1 3/4 into 2 1/5 log that I will reduce back to 2 inches.
Hooker is a nice product but requires you to build connection from their header to your turbo, places the turbo too far forward in many cases, and is ductile iron so will rust and is difficult to weld. Their v-band connections are also non interlocking, which is not always the best seal for turbo applications. Ours provides a compact and direct mounting provisions for the turbo that works well for many common applications. Cast from 304 stainless steel means it wont ever corrode and can be welded by anyone with a basic mig welder. We also use a male/female vband for the cross over to help with sealing and locating of the cross over. Also Made in the USA and includes high quality gaskets to seal everything up nicely. In the end, it really depends on what the end users application, budget, and goals are.
SWEET!!! I have Joey's hand built manifold, ordered the same Edelbrock Intake, crazy cool to see what my setup is going to look like... I am stoked. My guess is the drivers side is the Hooker manifold
As someone who fabricated my own ls turbo manifold , I will be giving you a call to order my next one. 😁 Mine turned out real nice and has lasted 5 years now but what alot of work. Nice job on the twin scroll
Excellent work. I don’t like the tank the throttle opening should point toward the top of the plenum rather than right at 2 of the ports. I’m sure that it will do really good. I have to think those cylinders right behind the throttle opening are going to flow drastically more air... example of what I’m talking about is the Holley hi-ram they do that for distribution.
