I don't know. This motor has me scratching my head. It makes more hp & tq than a stock HD, but the M8 closes that gap. Where HD shines, let her breathe, add a cam, & she really comes to life. This motor doesn't react the same. Tq goes up, but hp doesn't jump like a HD. Not sure, but it might be the intake runners, they're massive & short.

There's a kit out with headwork, cams, 117" etc, that runs about 110hp & 130tq. I can install a set of cams That do that by themselves! The only thing I've seen that increases hp numbers is boost. That tells me the heads flow, as long as they have the air. They just don't have the velocity by themselves.

I see absolutely NO reason to go big bore on this bike. I might do cams, but I'm thoroughly pleased with intake, slipons, & a good tune. It don't take long to get up to cruising speed, that's for sure!

Her you go. Fits on their 121 big jug kit as well.

Yep, Lloyds & someone else posted liked 150hp, 130tq. Too much for me, but wouldn't turn down a chance to wick the throttle on one tho!

Loydz's website said it could be bolted on in 2 hours. Would be fun but probably not very practical.

[speedjunkie]

Not practical at all, but still a hoot if a guy & bottomless bucket of $!

Nothing wrong with a turbo if set up right.
Read that at least twice.
Per bike platform, they look ugly as there is nowhere to hide the stuff.
Next, and the big one, if it can be bolted on in an hour or two, that the cheapest HP per dollar One will ever get!
5 to 6 grand is cheap money compared to what it takes to get real HP.
For under six Grand, that should bring out a minimum of 30 HP and Torq. Probaly a lot more.
It does not get any better than that.
The dwn side to this-
This shows that Indian like Harley is making super low compression models so as to sell more stuff later.
Thats bad- because they left all the HP at the factory on table.
Thats good- cause a turbo will bypass them and all the hype for less money and better results.
I would take a turbo in a heartbeat over Boring/stroking, head work, cams, etc, etc.
For one- the engine only makes power when you ask it.
Two- it does not have static High Comp.

Bolting a turbo on an antiquated V twin is like putting lipstick on a pig.

[thumper 549]

It is whatever anyone wants.
I agree they ( V Twin) are antiquated and archaic,
Dont tell these people about Lipstick and pigs.

Oh... I don't know about an "antiquated V twin" but on the VTX1800 V-twin a turbo really wakes up the stock engine with 160 rear wheel horse power and 140 ft-lb torque.


And the Turbo VTX1800 I have setting on the build bench is going to make 200 RWHP with a highly modded engine. I have been playing with Turbos for many yrs including, but not limited to a 1979 KZ1000, 1972 HD sportster (trying to keep up with the turbo KZ1000 and it could not). The turbo lag on the HDs is horrible and why I recommend a Magnuson Supercharger or MagnaCharger if you want to make good power from the HD tractor motor, it will make them a runner and if the engine is built right they will live for a few miles. If you must put a turbo on an HD then the only turbo I'd recommend is the 53 Series http://aerocharger.com/aerochargers/53series/ Aerocharger Variable Vane Turbo http://aerocharger.com/aerochargers/ like I use on the VTX1800s with a Bell Engineering vacuum adjustable fuel pressure regulator.

With this set up you don't need to run a pop off valve and the Aerocharger has very little lag and spools up fast, does not need to be tapped into the engine oil system as it is self oiled with it own oil reservoir, they are great turbos for most any engine under 2 liter imo.
