Sure.. when you coming over? I'll buy ya one.. :biggrin:

I agree with that. My whole argument was that extended wrist pin and lower rod bearing life would be minimal if any and is not the key benifit to a long rod crank. (IMO the piston skirt wear is the primary benifit for increased life) Loads on the bearings will remain the same with long rods unless resistance is reduced. Long rods dont reduce the resistance they only provied a mechanical advantage against it. But you did make a VERY good point that with reduced side wall friction less resistance will be obtained. :thumbsup:

did we scare him off already? :biggrin:

You just need to find a smaller wife.. You can be 4 inches and get the same ratio... :ninja: :yelrotflmao:

Good points :thumbsup: I agree with all of that! I never thought about the port area being open longer with a shorter rod.. It makes sense though..

wow.. wish i had a set of T-6's.. lol

I agree. That sounds like a plan. :thumbsup:

expander.. tension.. same thing.. :biggrin:

TTT Great motor at a great price.. You can't build this motor for 3k

I made my point. NOW i'm done.. :biggrin:

LOL Really?? are you serious?? You just proved my point!!! That whole reference was referring to the mechanical advantage of the long rods and does not change the force or reduce the amount force. It simply reduces the EFFORT (Mechanical effort) to apply it. ok.. I'll use your broom stick approach. to prove the load doesn't change or get reduced. Take your broom and tie 100lb bucket of rocks to the end. Now stand on a scale and point that broom straight over your head. Does the scale read 100lbs over your weight? it should.. lol Now take the broom and angle it. does it still read 100lbs over your weight.. probably so. Now was it harder to hold it out at a angle compared to straight up? Probably.. but did the scale ever read less due to the angle?? NOPE! What your referring to is a reduction in mechanical effort.. not a reduction in force on the bearings... I wont comment on your last paragraph about the pistons job to turn heat energy to mechanical energy.. you'll have people heating their pistons with torches to increase power.. lol

It might be a tension ring.. I've seen some piston manufacturers include them..

I think the last time I went to bobs.. there was a bike drag ported by RB.. I was very impressed.. :thumbsup:

What do you know about pirate hookers?

yeah.. what do you know.. :biggrin: lol

since the original question was answered and eveyrone is willing.. i'll keep going. Exactly my point... With out no hard evidance.. its therory.. and a therory is a educated opinion untill is proven a fact. Until you can prove (with hard evidance) there is a significant load reduction on the bearings that would create a noticeable increase in bearing life .. then your statements are theory. Is there extended bearing life?? maybe... I never said there wasn't.. I just said it would be minimal if any and it is not a key benifit to using the long rod. And thats my "theory" on that. Now heres my theory on this.. as far as direct force.. it does matter if its a rotating assembly.. the only DIRECT force on the bearings/rod is at TDC and BDC --> ------- <--- is a dricet force.. you move that rod in the middle.. Its no longer direct and the crank will spin and there is no more force on the bearings because there is no resistance.. to have force on a part... there must be resistance. What generates the force on the bearings? resistance.. where is the resistance? Compression. then the rod angle has no affect on the load of the wrist pin and neeldle bearings. Force is applied directly to the piston (from compression) and from the piston DIRECTLY to the wrist pin and bearing. the needle bearings are designed to take the force from all angles.. where does rod angle come into play here? remember.. physics stats for every action there is a opposite and equal reaction... force is applied directly (opposite and equal) I also highlighted a part in your quote that has to do with the law. les angle.. equals less dirct force on the sidewalls.. Compression is your constant force.. if compression remains the same (constant) unless compression is changed.. the angle of the rod will not change the amount of force applied.. only the angle at which it is applied (hence.. less side wall force)... the bearings are designed to take loads from any angle and the load on the bearings will not change until compression is changed. 165psi is 165psi.. it dont matter what angle..

yeah.. or you can use grease.

the 2 big ones go on the bottom of the main head shell.. 2 go on to the domes then 2 go inside the head by the spark plug holes.. thats it.

it would make a good dune pipe.. but.. I think the CPI would be the better choice for drag racing.

This is why.. lol My wife wasn't happy I made the mess in the office.. but.. its the only way I get a chance to work on it. Should have the cylinders bolted up and clutch componets on tomorrow..

PT's will have more low and mid but not as much on top.
