It would be really cool if you could give a roundabout figure of what a motor like this would cost to build. It would give your viewer an idea if they would want to pursue something to that degree or not. If you could do that with each engine you put on the dyno it would be even better.

[@vehdynam]

Great video . Kyle is really stepping up to the plate, very knowledgeable . Lots of information here . Thanks so much.

[@Headsup9550]

I'm surprised that Kyle isn't more familiar with tuning pid values, as I know that he tunes a lot of high HP cars. It's not a a huge deal, it's just swinging too far and as a result recovering too far trying to keep the boost regulated. Your wastegate manufacturer won't even be able to tell you exactly what pid value will be best, you will just have to perfect it based on a lot of factors per application. The best resource for learning this is KZbin and make sure you're not searching for automotive pid tuning in your search, the best videos are people explaining how to tune pid values in a generic sense. Computer geeks that control things through a circuit board use pid values for everything and will explain ensuring that your "P" value isn't too aggressive, thus won't require such an aggressive "I" value in order to bring it back within range and the significance of the "D" value. I like this setup in the video!! That setup is going to get it done with some dome pressure and timing!! Great video!!

[@Motorsportkyle]

Thanks for the input! Yeah particularly on the holley stuff ive never had to change it before its just always been right. I will definitely be experimenting and looking into it more!

[@okiebob5873]

I didn’t see his numbers but assuming his proportional isn’t too aggressive he should be able to smooth it out with a little more integration time.

[@mikealfieri641]

I saw the title and was thinking CLICK BAIT an LS cant do that with head gaskets! Then I saw it was Steve Morris, and all doubts went away.

Thats a lot of power from an LS with that little boost. One hell of a combo

[@markim5087]

These are some of the most drop dead gorgeous pieces of metal known to man kind, :)…

[@skullhart]

26:10 Interesting anomaly on the dome pressure. Wonding if there is a way to add a standalone sensor to verify the surge or investigate turbulence from the union flange where the turbos join. The bend in the tubing on the passenger side turbo might generate just enough vacuum to vortice. A high velosity leak also appears behind the drivers side turbo during the last pull. Lastly, the turbo union could be causing the issue due to its divergent shape which slows air flow and causes pressures to lower. My money is on if you were able to check pressure before and after that union I'd bet you'll see a difference. I'm just a retired jet engine mechanic so take it for what it's worth.

[@codylapoint]

I also thought that the merge point looks a little questionable. The way it steps up in size right after could cause a low pressure pocket to form and cause the air to swirl back creating turbulence.

[@BassManBobBassCovers]

Attention to detail definitely pays off! That level of power is insane for that engine.

[@hrsniperguy]

good you are getting Kyle onto the Vids, always good to see the next generation.

Great job Kyle. At 26lbs of boost this LS should zero problems with head gaskets. I can't wait to see a SML on a dyno with about 35 - 40 lbs of boost.

I suspect you would just see a cracked block....

Boost tells you nothing. It's just a measure of resistance. Cylinder pressure is what kills things. You can hurt things with 15 psi and make things live with 30.

[@Jase877]

Awesome video. I don’t tune cars but do have a lot of experience in PID tuning normally we done play with D as you get a lot of oscillation from the output while trying to control to a setpoint if the process can’t correct as fast as your trying to tell it to go. Play around with “I” as a fine tune to get it to creep up on your setpoint. Look at P as the first big push to getting to a setpoint. You may know this already but hope it helps if you didn’t.

Hey bud this is Charlie from Western PA I was just wondering could you put an engine plate on the front to tie the turbos in to keep everything calm especially the vibrations through the manifold cuz you guys are pumping out some good horsepower and there's a lot of shaking and I thought you know either not don't have to be a whole plate but just maybe something that ties it into the motor so it feels like it's one when it's cranking out some horsepower just an idea bud you build a hell of a motor brother hell yeah brother Charlie Western PA

[@Relleum68]

I think you guys are the best in the business hands down. I just have one question about some of these twin turbo setups I see (not just yours)… why not use mirror image turbos? From a plumbing/aesthetics standpoint it just looks odd. Is there a technical reason for not using RH/LH housing? Keep up the great work! I hope your channel and business in general continue to grow. You deserve it!

[@Jordan_Rush]

I am sure someone will correct me if I am wrong. With mirror image, you have to carry a left and right turbo in the event of a failure. I do love the look of a mirror image setup!

[@Dr_Mike2]

@Jordan, you're correct. So with mirror image you have to have 4 turbos total to have a spare on hand. With standard turbos, you only have to have 3, because they're all interchangeable. However, I'm guessing this motor to be @ $70k you'd think another $4k for an extra turbo would be more an investment than a financial burden.

[@MrAnviljenkins]

Pondering on Cletus issues with the mandrel on Mullet led me to wonder if there is good reason to put a pickup on the fuel pump pulley. If a setup has enough inputs monitoring that rotation could be an engine saver ?? Maybe same on the oil pump pulley ?? Shutting the engine off after we fail to see something like 5 pulley rotations on either one would be better than the lean condition shutting it off at peak HP and 1000' typical engine RPM ?

Prob a stupid question but why do you have 2 4in pipes from the turbos compressed down into a 4in then to a6 inch. Wouldn't that hurt the turbos.

[@djrisberg]

Could the dome pressure oscillations possibly be caused by the dome pressure lines physically bouncing around on the engine? Seems when you hit high boost at high RPM on the dyno, the lines were bouncing around pretty good...Either that or the valves in the wastegate (one or both) are sticky... and when the dome pressure spikes to compensate to unstick them the springs decompress and over-open the gates and then the dome pressure drops to get boost back...then the wastegate returns to its sticky spot and the cycling continues...you could test that theory by running with a stiff spring(s), maybe 15# springs and see if it levels off...and also cycle each wastegate valve by hand and see if one or both have a rough or sticky place somewhere in its range of motion. Pls post what you find when you figure it out.

@@AB-80X well a cooler will reduce the intake temps and that increases the density and that yields more efficient power . They mentioned running this thing on pump gas too. Doing a high end build and leaving obvious power on the table just seems bizarre to me.

I'm a little surprised on the cold side design. It has a pair of "small" individual runners that then merge into what appears to be the same size, before a cone up to a larger diameter. I would have expected the merge to be designed to exit at the larger size. Maybe it doesn't matter much given the boost level but at these power levels I'd expect the little things to matter.
