Some men look at porn... I look at old harleys... That is one impressive beautifully crafted machine. I could see Jesus riding that.

Amazing creation!!! I think your cooling fan could do with an up grade though ; )

What displacement is that engine? I don't see that anyone mentioned the engine size, just that it's a flathead.

[manuelito33able]

god dammit man with turbo

[Th3Art0fRu1n]

These old engines are a lot harder to come across now. Much less a turbocharged 90HP one..

The flatheads put out around 36HP (correct me if I'm wrong). You guys almost tripled that! (x2.5) awesome.

To get 90+ HP from a UL Flatty is sick!!  Its not your New Evo or Twincam,This is an antique!!WoW!!!!

[ndeep45]

freakin Hot ! thanks for showing it,

[ndeep45]

Man!! thats just too freakin cool

thats a ul rigtht?

[americancyclefab]

@ndeep45 Yup, it's a UL for sure.Thanks for your interest.

[turbospirites]

Does anybody read the description before posting? the motor is 1938 90hp 111tq is impressive for a flat head motor! A 221 v8 ford flat head motor only produced 65 horsepower in that era this thing is a V twin!

OH MY FUCKING GOD. GOOD MUSIC ON YOUTUBE VIDEO FOR ONCE. HOLY SHIT. Is the ice for the intercooler?

[americancyclefab]

@magnum9987 Yes, the ice is for the inter cooler. Takes intake air to below ambien air temp. Is only good for about 5 mins. Thanks for your comment.

[JacksonMooresExotics]

So it only has 90HP. That is not alot of power. It looks and sounded like it had a lot more go/

[ndeep45]

@JacksonMooresExotics dude do you know anything about motorcycles and hp?

[jcthawaii]

@JacksonMooresExotics You don't know squat about motors do you? That is a 2 cylinder FLATHEAD more than 70 years old stupid.

[bugratoksoz]

what is the music name?

[TwinCamSam88]

Wow

[americancyclefab]

An immense amount of work has been done internally - everything you could imagine to be able to sustain this kind of torque and horsepower. Among other things a special set of turbo cams designed and built by American Cycle Fabrication. This motor pulls 70 horsepower naturally aspirated!

90 horses from a ul flattie.....impressive,what was done internally to achieve this?

[stosja]

@MrRooster67 guzzi!
