Hard1 has the most HP of any DS that I know of on motor!!!! I told Eric that I wanted 1 port job just like his on my 855 LOL

 

So you believe the difference between your two machines is in the porting?

 

The only difference in the 2 motors is the new generation of porting!!! His motor rocks!! I cant wait to get my new 855

 

It was said before but if he would not have broken he would have the builder trophy!!!!!!!!!!!!

 

Here's some puzzling questions to ask about porting.

I wonder whats better about big valves? You would think the air would have a bigger obsticle to get around as it tries to get into and out of the chamber.

Do giant ports make more bottom end power or topend power? They usually seem to lose bottom end power I wonder why?

If a head has big ports shouldn't it have cams to match? If you got big ports you need big cams to get the most out of the porting right.

Is it possible to gain bottom and top end out of porting? How could that be possible?

What really causes an engine to gain power from porting? Shouldn't the porting be smaller to gain velocity and get the air in faster?

 

You tell me

 

Excellent! A new challenge. I will work on it.[img]i/expressions/face-icon-small-happy.gif[/img]

My 730 has a ported head by HPR with larger valves and HPR3 cams. I could not be happier with this combination. I just leave it in 3rd gear and dune all day long. I can lug it in 3rd and the torque pulls it out of the hole, and then it will just scream to 9k rpms with no signs of the power coming down.

Sandbomber, if I were you I would ask for a port job BETTER then Hard1 or else it too will probably be out dated.

 

I DID!!! LMAO

 

Thanks for the pics Jed, I want to responed to this thread but I need to take the head off and see what happen first! Couldnt have waited one more day the coast was perfect.
