Size matters...let's get some real motors in an HD...
« on: June 18, 2007, 08:52:43 PM »

Let me see now, Kaw has a 125 cu. in. Suzuki has a 109, Honda a 108...lets see a 131 cu. in. base line up to a 170 cu. in. TPI motor, Harley can do it. I saw an article on a guy who cut off two cylinders from a WWII British Bomber, ...5.7 litre, 350 Cu. In. that's what I am talkin about...BIG INCHES to eat that JAP CRAP...PERIOD. If it ain't big...leave it on the porch.... :orange:

Rumors have HD planning the following engine displacements for the next few years:

2000 cc = 122 cu in

2200 cc = 134 cu in

2400 cc = 146 cu in

You don't need big inches to make power.

My little 1300cc makes 253 RWHP!

It made 172 RWHP stock.....

Big cubes add a fair share of vibration, cooling issues, size constraints. But it sure helps for bench top bragging rights. :D

Considering all the issues H-D has had with 103 in3 and 110 in3 engines, especially in the area of controlling heat, I think they would be better served by improving the efficiency of the current sizes and leave the monster cubes to the aftermarket.  At least until they convert to water cooling. ::)

You don't have a clue do you?

It's not the size of your HOG, it's what you do with it that counts :)

I may be way off here with this assesment, but I think HDs size increase has very little to do with making HP/TQ, and a lot more to do with meeting EPA guidelines. As the EPA restrictions get tighter, the fuel setting gets leaner, and the timing gets "adjusted" too. So to make up for the losses caused by this, the engine gets larger.

First there was the EVO. An excellent carburated engine. Sure some of the early ones had case problems, but by and large it was a good engine. There are Evos out there today that put out more HP/TQ than some TCs. Then the TCs came out and they all ran hot to meet EPA. Then HD went with FI, first the M&M crap, then Delphi, once again to meet EPA. Then they had to add O2 closed loop to continue to meet EPA. The FI 88s ran hotter and leaner too. Now HD comes out with the TC96, and once again the 96 is one of the hottest running bikes on the face of the planet. Many of them just shut down due to heat management issues. In my opinion the added inches is an attempt to make up for more losses due to EPA. Water cooled is here in the version of the V-Rod.

An alternative, X Wedge by S&S. Preliminary numbers show decent power for a EPA air cooled twin.

I find that most don't realize the power that a small displacement water cooled motor can make. Along the same lines I run a small block in my drag car, against the normal train of thought. ;)

At some point, the MoCo will expand their water cooled offerings, IMHO.  Not sure on what is in store for these sizes - patent applications for them indicate HD wants to step up a bit more in the TQ & HP game.

Expect less mods to be offered to existing engines from the MoCo - this EPA stuff will supress dealers but offer a boom in the aftermarket, unless I read it wrong.  So many times, I read it wrong......  :nixweiss:
