This is kinda crazy...... But ingenious.
Think rotory with a power stroke every 33.3 degrees.
I love the tech involved here.

Hey I have some of those!
I see some cool here. What am I looking at please. Has to be a Ford so go from there.....
Yup.Hey I have some of those!
Well it was supposed to be a numbers matching stock 302 in a ‘68 Shelby GT350. It came in for a re-seal and swapping out the 4 speed for an automatic because that’s how the car was born.I see some cool here. What am I looking at please. Has to be a Ford so go from there.....
The question isn't "will a single wastegate do the trick" but rather "if I put the waste gate in a position where it only gates one half of the engine, will that cause a backpressure issue."Look at the Cat C-15 accert motors they used a compound set up.
Small turbo would spool fast. Then the big turbo would take over to the tune of about 40 psi.
Great bottom end performance. I cannot remember but I believe they only had one wastegate.
The wastegate exhaust will still be directed to the larger turbo right?The question isn't "will a single wastegate do the trick" but rather "if I put the waste gate in a position where it only gates one half of the engine, will that cause a backpressure issue."
Also, I'm basically cramming the entire exhaust into a tiny T3 housing flange. It's just a lot of exhaust moving into a very small space, which has potential to increase backpressure and cause issues. Adding the extra gate should help it spool the larger turbo faster while also relieving that pressure.
What I don't know is, if I only gate half of the engine, will it even out the pressure on it's own or will it do some kind of funky backpressure thing with one half of the engine.
I may just have to do it and put two back-pressure gauges on the car. Maybe a third. One for each half of the engine and one leading directly into the turbo to see what the turbo pressure is.
Yes, it would still be directed into the bigger turbo.The wastegate exhaust will still be directed to the larger turbo right?
If so I would think it would even out, but I'm not a turbo guy.
Could you run the small turbo off of one bank and then the exhaust from that turbo and the other bank exhaust into the larger turbo?
As long as the piping was sized big enough I imagine it would work, but hell I don't know anything.Yes, it would still be directed into the bigger turbo.
What you're suggesting is kind of what I'm wondering would effectively happen. I would be putting the gate right before the turbo at the collector. So if the gate opens, theoretically it would vent that bank directly into the big turbo.
AKA - system starts off with both banks lighting the little turbo, then quickly moves to one bank lighting the big turbo. At least in theory.
So actually, on compound setups the little turbo is fed by the big turbo.Talked to a Cat guy He said the small turbo will feed the big turbo. Like you explained but that’s for a I6 don’t know if the V8 would change the equation?
My brain hurts trying to think about it!
So actually, on compound setups the little turbo is fed by the big turbo.
Exhaust enters the little turbo first, then goes out the little one and into the big one.
For intake air, the big turbo sucks atmosphere air, compresses it and sends it into the intake of the little one. Little one then spits the air into the intercooler and then the engine.
I agree with this.Best practice I’ve seen pretty consistently across turbo builds is to put the wastegate as close to the collector as possible while maintaining good flow. Putting it 90 degrees to the exhaust piping anywhere in the system will not allow you any control.
