Building a Turbo '04 Sportster 1200 - Full Build + Camshaft Comparison

[@michaelbrinks8089]

Turbocharge Everything!!! 👍

[@DoctorMotorcycle]

Hehe you know me Mike!

[@drunkredninja]

no annoying music, jibber jabber or long winded explanations just unintentional asmr with useful pauses of information. quality.

[@ryanpaulik864]

This bike was my coworkers, and now owned by my long term hooligan buddy! Great work! Look forward to riding with him.... Maybe you can do my 17 Victory Magnum x1 next....

[@TineEdong]

Turbo your bike Ryan!!

[@oricardoribeiroh]

Oh boy, it just puts a smile on my face seeing a new turbo project

[@TineEdong]

The smile on my face doesn’t come off!!!!!! It’s so much fun! I’m not scared against rockets now! Lol

[@SloppyMechanics]

i love your videos thank for doing them

[@robertwells6454]

Great results, great sounds out the pipes & I'm sure more fun to ride. 👍

[@DoctorMotorcycle]

100%, the cams really woke the bike up. With the stock cam it hit hard at 3,000 but the top end power felt constrained. With the cams it will power wheelie!

[@robertwells6454]

The Bike sounds great with that setup.

[@TammieDessa]

Another Amazing video Thanks!

[@basilrehmann2631]

yesssiiirrrrrrrr, been waiting for that one

[@DoctorMotorcycle]

Thanks Buddy, enjoy!

[@joseflores-mz2rl]

Been waiting for a new video! Thanks brother!!

[@Pleksilasi]

An awesome project man, well done. Tell us, what is your thought process when choosing the next project? Do you just go willy nilly and slap snails on anything with 2 wheels? Or is there some prerequisite or other method to your madness? Like choosing bikes with very low natural compression ratios to stay safer with knock? Tell us sensei! Cheers!

[@DoctorMotorcycle]

Thanks, it's mostly whatever the customer owns and wants turbocharged. The past 3 builds have all been commissioned, so I don't have a say in what bike it is. But we're going to be focusing on Sportster based engines from here on out - Buell XB, Sportster, Tube frame Buells as well as Ironhead Sportsters, and eventually Harley Softails. I'd like to build a Turbo Vrod, Harley Softail etc. But it seems like people need to see a build on their exact bike before they take the plunge. We can do Japanese bikes too but I have to follow the money, and with Harley riders, $4-6k isn't a big deal

[@TineEdong]

I would agree with the money part. Trask is selling their kits for more money and NOT installed. This is a bargain for not needing to buy a 20k worth of getting another bike.

[@jerrybigrig9475]

😎👍😎 ..

[@joemahan311]

Do you think a turbo kit would affect highway cruising or is that just dependent on revs?

[@DoctorMotorcycle]

During 70mph cruise it doesn't make any boost, but as soon as you accelerate even a little bit, it will make boost. It's dependent on throttle position - 3/8 throttle will make 5-6psi, and anything above that will be at or near full boost. Highway fuel economy is very close to stock so long as you're cruising without getting into boost a ton.

[@ohexra]

i wanna ask, can you turbocharge a single cylinder? since the power is pulsating a lot would it affect the output perofrmance?

[@DoctorMotorcycle]

Yes, but you need a BIG plenum and an intelligently designed turbo setup with a relatively large turbine housing.

[@petergriffin4629]

Did he make a detailed video comparing blow through vs suck in carb set ups? Is the suck through worse?

[@TineEdong]

They’re a little different he explains things on patreon

[@GingerPiston]

Wow…so you CAN polish a turd. Remarkable.

[@TineEdong]

😂😂😂😂😂

[@TineEdong]

I’m keeping this turd now lmao

[@kramler]

11:11 that pension is sus

[@TineEdong]

It definitely rides better than my factory 14’ 883

[@chriszeis5477]

How about a liquid cooled twin turbo sport bike or supercharged bike

[@Ghettochappy]

That bike should have double front brakediscs ,aftermarket rims?

[@DoctorMotorcycle]

Yeah, someone stole a bunch of stuff off this bike, I think it may have been wrecked at some point. The forks were missing and it should've had the high performance .551 cams, it ended up having the low performance W cams. Bummer, cause those the two main things different on the 1200R

[@Ghettochappy]

@ that sucks man! Yeah i have a sportster 1200R 2006 ,ive read that it should have somewhat bigger ports in the head to but i dont know.. Very cool turbo build you did I might be interested in a kit

[@TineEdong]

It’s the one thing I hate about the bike honestly. I knew it should have had them and it was such a heart breaker when I saw the W cams. W doesn’t mean winning either damnit! lol I’m glad the Doctor told me to get cams that will be better for turbo applications. Replacing that front end with factory forks is like 3 grand…. 😭 and I hate spoke wheels too but again, finding factory ones are really hard to get.

[@Goku69762]

I wanna see tubo charged lawnmower. Cuz that's the engine in my bike 😅. ( Prolly lower capacity 😢 )

[@oldgangster4119]

Bro put riding video of gt 650 on 2nd channel

[@DoctorMotorcycle]

Unfortunately I don't have much riding content on the Enfield, but I can put together a build breakdown that has a couple of pulls and wheelies in it.

[@grabir01]

At 17:29 that Buell was tank slapping! Yikes!!

[@DoctorMotorcycle]

No, that wasn't a tank slapper, that's called headshake. Headshake is due to gyroscopic procession (how a motorcycle stays upright going down the road), and this will be apparent under hard acceleration with all motorcycles that have enough power to pull the front wheel at higher speeds. Headshake is normal for high powered motorcycles, and is not the same thing as a tank slapper, which is complete loss of control of the steering due to violent, lock-to-lock bar shaking, which that was obviously not.

[@grabir01]

@@DoctorMotorcycle That was the beginning of a tank slapper.

[@grabir01]

Not a good idea as these sportsters will tank slap when you get above 90-100 mph. Solve the handling problem before you do any power adders.

[@DoctorMotorcycle]

I already discussed how I took care of this in the video, pay closer attention. 100mph is a speed most responsible adults will very infrequently hit anyway.
