Hey there,
Pre-production Turbo kits for 1986-2003 Sportsters are currently available, reach out to us via our website to inquire. www.doctor-motorcycle.com
The bike is a 1994 Harley Sportster that I built over a year ago now; I've put 10,000 miles on the bike, as it's been my daily rider. We've collected a ton of data over the past year riding the bike every day, and it's from this data that we developed the new and improved Version 2.0 kit.
The new turbo setup utilizes a much smaller GT15 turbo (carbon sealed), which spools WAY faster than the original, as you can see in the comparison at the end of the video. The comparison portion of the video was actually posted and uploaded on patreon a month ago. The new setup also uses a custom programmed ignition box, with our own timing map that took many, many hours of testing to develop. The new turbo setup is better than the old one in every way.
For those of you that want help and guidance with your turbo setup, our "How-to Turbocharge your Carbureted Motorcycle from Scratch" video will break down EVERYTHING; Draw-Thru (including carbon sealing), Blow through, from fuel pump selection to vacuum line routing to setting up the fuel pressure regulator and more. We have an additional 10 how-to videos, from tank painting to cable modifications.
If that isn't enough, I'll be there to answer any and all questions you have.

I’m new to motorcycles, but I’ve always liked the simple design and size of the sportster. Yours is exceptionally killer how you’ve trimmed it up a bit here and there. Even without the turbo setup it looks fast and aggressive. Definitely some cafe racer inspiration. You do some amazing work.

Thanks, before building this bike I felt that many custom sportster's go for a similar look, which I was trying to avoid. Many people see this bike and don't realize it's a Harley, which is a complement in my eyes. Cheers!

Thanks for the compliment, however, I'm actually naturally very bad at mechanics and it didn't come easy to me at all. I've been working on dirtbikes/cars/motorcycles since I was 12, and I didn't even consider myself proficient until I was 25-26, and only recently started hitting my stride (I'm 29 now).

Thanks Tyler, though I do wish I would've bought one sooner. That's one of the reasons I haven't sold my KZ650; the turbo setup was all flux core welded, and it looks so bad I don't want to sell it like that. The next video is actually going to be me bringing that bike back, and making it the monster it should've been. Cheers!

@DoctorMotorcycle Жыл бұрын

I did in the original build video, check it out, it's on the channel near the end of the video. Stock sportsters of this vintage do 0-60 in mid 5's, so to hit 3.9 with a soft baby launch is very fast. I believe if I raised the 2-step and committed to a full throttle, full boost launch, 3.5/3.6 0-60 would be doable on low-boost.

Nice work, glad to see you arrived at the same turbo as I did. Quick tip from my side: the Ignitech (I think since version V.88) can do boost retard, so you can make the bike even more lively, by running more ignition advance boost and then retard it one degree per pound of boost to keep it running A LOT cooler. Pressure switch can either be bought from them in CZ, but as it turns out, it's just a generic Bosch map-switch, as found in many Volkswagen/Audi turbodiesels. That'll probably shave off another 2 or 3 tenths off the acceleration time.

@DoctorMotorcycle Жыл бұрын

Yeah, I'm running a hobbs switch which activates an alternative ignition map, and have a MAP sensor on hand to install as well.

@gregsochor Жыл бұрын

@@DoctorMotorcycle Excellent choice, I tend to forget that the new(er) versions even can switch between maps. Curious to see how the bike develops. Do you plan to install a burst panel on the plenum or do you expect the rubber hose to pop off, when it back fires?

You need a good annular cutter kit for your drill setup. Those step bits are terrible. Once you get one of those annular kits you'll never go back. The good ones last too. Nice build btw! Excellent spool time too

Thanks, surprisingly I've never heard of these, and will look in to getting a few. The step drills are actually pretty handy, it's just that stainless steel is hell on drill's, especially cheap HSS/cobalts. Cheers!

@@DoctormotorcycleToo I'm laid up at the moment with a surgery, but I'll be at my shop in a couple of days. I'll try my best to remember to find my kit and see if the companies name is on it. If that's the case then I'll get back to you with the name, ect. Those annular cutters ROCK! Check with your tool suppliers as well, they might know where to get a good set. I bought my kit in '13 or '14 and it's held up admirably. I just don't remember off of the top of my head who made it. It's American made, that much I do remember. They cut quick too. Oh yeah, before I forget, get Rapid-Tap for a cutting fluid. That stuff beats all of the plumber grade dark cutting oils, ect. hands down. If you use it your cutters won't overheat and wear out. Cut real slow with that stuff too. It'll actually push faster through the steel that way. I found out about all of this stuff working in a diesel shop for a pipeline company. Cool turbo setups boss, your builds rock out.

@DoctorMotorcycle Жыл бұрын

I've thought about it, I'm still leaning towards no just because of how many additional questions and support I'll have to offer people who are either first timers or are just not super experienced with turbo's. I've sold a few carbon sealed T25's locally and one guy installed the center section upside down (fed oil through the oil drain/drained out the feed) and the other one hit me up twice a week with questions about jetting and help with the setup.

@zchambo1615 11 ай бұрын

Beautiful video, I have a few questions though. 1: are you suffocating it with the filter by your leg? I may be wrong here but having the turbo on the left side with wraparound headers and the intake facing forward might tidy it up and breathe better. Just a thought. 2: stock 1200 motor? 3: What do you think about e85? The e85 could benefit the lag on top of the gt15. Ive been running e85 on a stage 2 1200, stock carb with big jets (48,190) for the last 1k miles and no problems so far. 4: are you going to attempt boost by gear or rpm?

@DoctorMotorcycle 10 ай бұрын

Stock Motor, I've ran E85 before and it makes the driveability too crappy on a Carb'd bike. The draw-thru turbo setups need heat in the plenum/intake to run well, and the E85 keeps everything so cold it just doesn't run good until the bike is almost completely up to temp. It's quite a bit faster on Ethanol though. It would be the way to go with EFI for sure. Boost by gear/rpm not unless I try to max the turbo out and doing drag racing type riding, which I will eventually.

@DoctorMotorcycle 10 ай бұрын

Don't know if you know this, but the Buell XB bikes were originally supposed to be turbocharged, and most of the development was done with those bikes at 150hp with boost. Can't remember why Harley pulled the plug but they were close to production ready with the Turbo Buell. It's why the XB's had a hole in the left side of the frame, it was for the charge tube from the turbocharger.

Ive been debating between a turbo and Hammer 120hp kit for my 2000. Its my first Harley, but Ive had it long enough to be quite bored of the power. Why did you choose turbo over big engine? Also, I think I recognize a few streets from your riding videos. You in the Phoenix area? I just loved to the valley and been looking for places to ride.

@DoctorMotorcycle 10 ай бұрын

Yeah I'm in Phoenix. Going the all motor route is more expensive than boosted, and once you have the money sunk into an N/A setup, you aren't getting it back. With a turbo, you can pull off the turbo setup and sell it when you sell the bike and get 70% of your money back. I also like having a lot of torque down low, and being able to pass people on the freeway while just leaving it in 5th and using the grunt. Plus, If I ever want it to be an absolute monster, I can dump some Q16 race gas in the tank and turn it up to 12-14psi of boost and/or do a water/meth injection setup. I'm going to be selling these as a Kit for under $4k, 100% bolt-on, pre-jetted carb and you can install it in a single day easy. We're only a month or two away from the release of the kit. www.doctor-motorcycle.com

@@DoctorMotorcycle I ended up grabbing a 1275 Hammer kit, but not the big one. There was definitely a point where cost to power gains ratio became less than ideal so I got a smaller kit. I did opt for flat top pistons since I am still intrigued by the idea of going boosted and that leaves me some room to do so later. Im gonna get used to this kit once we're done with the bike, whatever weekend we can get to it and in another 6 months or so Im sure Ill be bored of the current power again and ready to start lookin at more upgrades. Sounds like you'll be done with the turbo kits by then so we'll have to chat. Honestly Im a little nervous to ride on the 10 or the 60 out here. Maybe out passed AJ would be good. Any good riding areas you recommend? Thanks!

@DoctorMotorcycle Жыл бұрын

What are you talking about burn your knees? The only thing inside your leg is an air filter, and part of the front of the carb. This whole setup is designed exactly to avoid that, there's 0 things warm near the rider. Supercharger is better? That would be a packaging nightmare on a sporty, and superchargers are are inferior to turbochargers anyway.
