Re: Dustom's Turbocharged Harley 1250

A CEAT Zoom at the front and a car tyre on the rear. And all this on a HD.

You sir are a genius or plain loco How's the bike doing? Any more changes?

Re: Dustom's Turbocharged Harley 1250

Not much of the stock mosickle left eh Dustom😂

Re: Dustom's Turbocharged Harley 1250

CEAT zoom was put on when I suffered multiple punchers whilr coming from noida tobharidwar and couldn't find michlin . This was the only tire that could go on.
Bike is doing fantastic , I am not !
Met with an accident when a ladder collasped and I hurt my neck pretty bad.
Now recovered enough to get back on the saddle.
Next I think could be front end rake and some weird handle bars. But that's not happning anytime soon.

Solo to friends place haridwar - ruderpur - haldwani. , 600km of unadulterated motorcycle Nirvana.


Just for some sound bite , that Turbo shrill.

Re: Dustom's Turbocharged Harley 1250

I am just wondering how the rear tyre would be doing even in a slight lean angle during corners. After all its a real flat car tyre. IMO

Re: Dustom's Turbocharged Harley 1250

Tons of clips for dark side car tire available on YouTube. Help yourself.
From personal experience , I can tell you anything above 40kmph , car tire is at par or better at doing everything than a motorcycle tire. At very high speeds like 120-140 , it makes better road feedback as well as so much better stability under brakes.

Re: Dustom's Turbocharged Harley 1250

If car tyres were better than the rounded ones, sports bike manufacturers would switch to those. Rounded tyres have an increased contact patch with the road during cornering.

For the type of cornering a HD does, I think a flat car Tyre makes more sense.

Re: Dustom's Turbocharged Harley 1250

We aren't talking sports or RR in here , anyway as I said , at slow speeds , this tire tries to react to undulations , pits , stones on the road , so you have to keep a firm check where the bike wants to go. As you speed up this tendency reduces n finally vanishes.
Manufacturers have to build for customers who have just enough cash , irrespective of riding experience.
I would not recommend it to a new rider atall , simply for having sort of a mind of its own at low speeds.
Just like in equestrian , not all horses are for everyone.
It is definitely a big leap forward under braking n wet traction.
I put it on for same reason that people put on ultra tall handlebars , 50*rake front ends , hard tail their rides . some say the reason is - look at me , I am cool .
Those who actually go down the less beaten path will tell you the reason is - middle finger to the world.

Atleast for cruisers and heavy touring ones , lots n lots of people are using car tire , gives better milage , tire life .

Manufacturers aren't using Turbo chargers as well in motorcycle , what are your thoughts on this subject?

Re: Dustom's Turbocharged Harley 1250

If you feel better results with car tyres please go ahead, boss. I'm a fan of what works best IS best. Since I don't own a cruiser and I probably never will, I'll take your word for it.


On the subject of turbos, I must confess that I have zero knowledge. However if the cost vs performance of turbos make sense to the bean counters, I'm sure bike makers would embrace turbos. The ninja H2R has a supercharger, and look at the price.

PS : Since you've taken all the trouble to put a turbo on your bike, and a DIY that too, I would love to know what is the total cost of it, and the real world performance increase you got from it.

Re: Dustom's Turbocharged Harley 1250

Most turbos @ dealership cost in range ok 50k , at manufacturers it's almost one third of that. I know costing at Tata and Honda , Gt17vnt costs them under 18k , costs in 60ies in open market.
Most manufacturers are able to extract twice the horsepower with same block and internals between a Turbo and NA .that with even more warranty and newer emission norms.

I have nearly 70 bhp more than what it left showroom with , although 30-35 increase goes to 883-1250cc conversion.
I could have nearly 15-20 more with factory reliability if I had gadgets n facilities manufacturers have. Another 20 if the engine was water cooled.
What it cost me is immaterial ,I knew what needs to be done and how, if you bought horsepower in open aftermarket , you would probably add it atvrate of 10-15k per horsepower.
if a manufacturer provided you with that much horsepower along with the fact that the customer having the feel good of having rare Turbo motorcycle , they would charge a lot more.
Money is charged for know how and R&D , specially when other similar motorcycle aren't having same or equivalent tech.

Turbos have made horsepower cheaper than any other single system in history of mechanical engineering.
Consider the example of most modern diesel cars , same blocks and heads produce 60-70bhp , when same car is equiped with a Turbo it's nearly twice . Turbo model being 2-3 lc more expensive.
So it is in fact extra 70bhp for 2 lc .
Classic examples are Tata and Mahindra.
So it is in fact adding bhp for nearly 3k INR for every bhp added.

Even in Upgrade market , parts Harley Davidson sells under brand of Screamin eagle performance parts , likes of cams , tunes , exhausts usually add 1 bhp @ 10kinr.

Re: Dustom's Turbocharged Harley 1250

Thanks for time you took to give out the info.

Did you test out the top speed your turbo bike is capable of?

Re: Dustom's Turbocharged Harley 1250

Naah , I never went faster than 190. 189 is my max recorded speed.
She will go to just about 200-205 , limited by rpm limiter , not power. But she goes from 80-150 like she is accelerating in 2nd gear. That's what I wanted with torque .

Re: Dustom's Turbocharged Harley 1250

What about tractability, does that reduce on turbo bikes? What is the lowest speed the bike does in 5th/6th? Also, can it do 10 kmph in second gear without lugging?
