Jim, you know there is a 7 mm crank for the zx14, right? We aren't limited to 1570cc.. Just sayin

Nice power there Karl. Whats that in SAE HP? about 270-272?
Are both motors 1635cc? same cams and pistons?
SAE = 272 just like you said; i just sent 2 pulls to you.
both motors are 1635, same short block config, not positive about cams.

Yep. But the rod bolt hits the clutch basket so badly that you need to grind well over half of the head of the bolt away. Even on a 5 mil there's quite a bit of the bolt head removed.
We have looked at solutions for these and other problems but the $$$ to hp ratio isn't good at all.

Looking good Karl, so that's .166 hp per cc, that's good. So you are right there where you should be on power.
Here's a few examples.....
Your zx12r with our cnc ported head was 235-240 on 1427cc so that's .164-.168 hp per cc
Brocks Busa with our cnc ported stage 3 head is 1696 cc and 280 hp so that's .165 hp per cc.
I know another "red hat" land speed racer (not sure if he wants to be outed) with a 1649 cc engine and our stage 3 head making 272 hp, that's .165
And Mike Garcia who set several records at Bonneville last year with our stage 2 cnc ported head on a 1340 cc Busa is making 223 hp so that's .166 hp per cc.
I think its going to be great at loring this year. I just hope we have good weather. We had some rain last year so that helps on this years odds.

Is the 7mm crank a billet?

Ain't that the truth'' With the Hayes convertible clutch basket and 7mill you have to mill the basket down ( A LOT ) and damn near cut half the bolt head off ! But the Hayes will hit the bolt on a stock stroke with Carillo H beams on the 14's ..........

Jim I like the way those head pipes look! I use a brocks pipe as most people do, but from day one I was concerned with the way that head pipe hooks up to the exhaust port ? The Brocks pipe uses a outward flange to meet the gasket and actually funnels inward a small bit. I guess the funneling in could help the back pressure but would also hurt the total flow. I actually like the factory pipes the way they fit the port, they turn inward to meet the gasket this allows a 1/8" all way around the port to help stop back flow of the cam. Ever race car header i ever seen the head pipe is bigger than the exhaust port to help with cam reversion. I am Curious See how your flanges meet the gasket.
Ken
that looks familiar !!
Hee hee! Now Steve you don't hardly mean you have seen this type port header configuration used/ designed by another do you LOL !!
We dynoed one of those freaking monsters last week and i still don't believe whats wright in front of me.. JESUS !!!!!!!!

Do I need an angled cap or bolts that come in from the pin end side of the rod?
The angled cap is used to fit on small bore applications, typically for clearance reasons. Aircooled Porsche and aircooled VW applications use a "backwards" bolt as it is tightened from the head side of the engine due to clearance requirements for the connecting rod in the engine block.

Bill, what size motor and what are you seeing for SAE hp?
1Bad, I talked with Noonan at Wossner about doing the 911 style cap retention for the zx14 to help with clearance issues. We are working with them on the design of the standard zx14 rod right now so it wouldn't be until after those are done. But It would be difficult to do with the zx14 because of the integrated cylinder and upper case. Access for torquing is an issue. We have been looking at some other options.
But then theres the deck height issue with big strokes as well. The bottom line is that the integrated cylinder is making life difficult for zx14 stroker motors.

Good to know you've researched it. Shame it requires so much clearancing. It would be cool to see a 16xx cc zx14 motor with your stuff on it.

Jim i thinks its very kool what your doing for the performance market. Kaw' especially ! The gear you designed has been a great success ,even more so then you have presented it to be.
I also have been seeing better torque figures from the TB's we got from you then ad, enough so that its required gear changes with lite jockeys at the wheel.
Gonna get with you tom, about shipping complete motor out to ya .
Thanks for your help on these 14's Its appreciated .....................

Yep that's the main issue holding us back right now. But, we have a work around for that also right now.
We are working on a tall deck, bigger stroke, big bore design now.
We have learned a lot from working with this last engine and are looking at ways to stabilize this engine.
I just wish we had more hours in the day and I was 25 again so I could work all night !!! I really love this stuff with a passion. Damn, I'd settle for 35 years old again !!

Gotta start making things lighter and losing some weight in area's to help overcome that CC advantage the busa holds.

Scott, as of right now were going to keep the gen 1 motor in the bike. But if we switch over tho the gen 2 motor at some point then we will make a big tube header for it.
Wreckshop, your right as far as drag racing. But in landspeed racing weight isn't an issue.
We are going to put the shop bike on a diet for next season, as we plan on doing more drag racing than land speed racing.
One customer called me joking that the head was too pretty to put on the bike and he was going to keep it on the coffee table. LOL
