V-rod TURBO Drag bike! Fabricating a turbo kit. Harley Davidson V-ROD.

Turbos. Today we're going to be making a turbo kit for a V-Rod drag bike. So the bike was already turboed but the owner contacted me with a few issues. So turbo was too large. He actually had a failure on the turbo because oil starvation issues and the headers. He just wasn't happy with the position of the headers, length. So yeah we're going to be making a whole new setup. New headers, new exhaust pipe, new charge pipe, everything. We're keeping the wastegate because it still works, still functions properly. But yeah let's get stuck into it. All right so here's the bike. That's the old header setup. So you can see in there that the front header is really short. Rear header is quite long. That's the wastegate there. The turbo used to hang down the bottom here. This is the old turbo. Look at the size comparison. So it's understandable that he was having spool issues with this. Like it's a giant turbo. This one I've used on multiple V-Rods. Perfect sizing. So this is still 500 horsepower capable turbo. Not that the engine is going to put out that much but definitely big enough. This one was far too big. So yeah. So the owner said he wants to put the turbo about here and try and even up the length of each header. And we need to work out the best way to route the exhaust. Obviously foot pegs are here. Your knee comes up about here. So we need to route the exhaust in a way that it's not going to burn him. And also we need to run charge pipe up to this plenum. So the old setup ran around the back and came up through. We might have to switch the lid around and come up with something else. But yeah let's pull off all the old stuff and get stuck in. All right so speaking with the owner of the bike he's opted to put the turbo right in the middle like we said. And we're actually going to face it backwards. So the charge pipe will actually just be a straight shot right up into the plenum. I'll show you guys in a second. Second reason is the exhaust it won't be too hot because it won't be pointing towards him if you know what I mean. So it'll actually come down the front of the bike and turn down. We've done heaps of kits like this before. I'll put some up on the screen now but uh yeah. So you can see there we've got a few pipes sort of mocked up. Turbo flange is going here and it's going to face this way. Charge pipe goes straight up into the plenum. Once this lid flips around you've got the inlet of the plenum right here. Try and do this with one hand. A little something like this. So charge pipe will go straight up. Exhaust will go down the front of the bike. All right there we got the turbo mounted. Don't mind the core it's not clocked correctly it's just how I put it on. You can see there the turbo flange tacked on. V-band there so we can make it removable. So yeah it's almost a perfect straight shot up into the plenum. Slight bend into it. It's going to be a turbo guard on the front and the exhaust is going run down here. Wastegate coming out here at the collector. The screamer will run parallel with the exhaust. All right it's the next day. I've been doing a couple of things off camera because I've got to get a move on. I'm not supposed to be punching this out over the weekend but anyway. Yeah so I've put the wastegate on and started tacking up the dump pot and I think it looks pretty cool. All right as you can see I've got the wastegate mounted. This morning I had to run to Harley and get some exhaust gaskets because the ones I had they were too thick to suit these flanges that were machined. So I had to go get some screamin eagle ones. I installed those today so these headers are ready to finish up. Just obviously tacked here and here. Wastegate is mounted and I've got a bit of the exhaust tacked up. So the owner wanted to use the original pipe but it wasn't going to suit this application. It was just one big 90 and it ended up sort of out here. But anyway I got these um I chopped up the old dump pipe because it's got the x-pipe already welded into it and the tip's already in a nice slash. So chopped up the old dump pipe and mocked it up here. Look at that. Follows the frame nicely. Nice slash cut out of the bottom and the screamin pipe is going to follow along and have the same slash cut backwards at the same angle of the frame exhaust. Exhaust follows the same angle as the frame. Looks sick. Very happy with that. So a few things left to do. Weld this out. Weld this out. I'm going to put a bracket across the two. Bolts them together. We've got O2 sensor bungs here and here. Finish welding out the headers there. Put a brace here to carry the weight of the turbo and that'll wrap this one up. So I'm going to put you guys on time-lapse and I'm going to get stuck in. All right there you have it. It's all finished up. Obviously it's got to go to the mechanic and get the oil drain line, oil feed line sorted. You can see the brace here that I made. It's welded onto the rear housing and onto the frame. This engine is hard mounted just in case you're concerned about that and
