Hi- I haven't looked at the cylinder head on the ZX-14 (yet) but was wondering if someone has proven results through porting this head and who that individual might be?
How closely are the cam and head matched? I.O.W. will there be power gains through head porting without changing the o.e.m. cam?

Thanks!

Try Slowninja. He races and I think he did that mod + thin head spacer.

Thanks Rook!

Ronnie,

How much proof do you want:

1. Sand heated into plate glass = Smooth
2. A tree = Smooth top table.
3. Rough = Mountain ridges ~ Peaks.
4. Micro look = Head surface or the ports are one lone mountain ridge.
5. Air travel = We get in the car and how long does it take to get from A to B if we cut down the mountain and reached the same distance without the climb over the port's micro-mountain ridge.
6. She Dat shit!
7. How does my air flow factor into you needing some proven results?
8. There is also the rubber spigot that needs blending to the ported head.
9. You nick that valve 45° valve face, all that work???
10. Cut down all the seats to match the head's cc you have to dress kind of head tuning or here we go again you chasing power.

Hub-
Before and after power numbers would be nice.
I'm not really interested in c.f.m. numbers as an indicator (#7).
People don't really cc match combustion chambers by sinking valves anymore...do they?? ;)

Thanks.

Ronnie,

If you were going to have 4 Olympic size pools for divers, would you have the pool level different than the other pools for the high dive? You tell me if they chase balance.

You would have to measure one step at a time to see who gain the most as in some way to measure. It is a speed event if #7 means anything to you. If I remove the steel mesh from the air cleaner, it moved the air in faster as opposed to the screen holding a lot of surface that the holes did not expose.

If I took the air cleaner out, I would have a 3rd less restricted air event to measure. Stock/Screen/Gone. And can you see there was no more air entering that cylinder if you need to measure some sort of speed event before and after.

Hello Hub-

When Pro Stock used to race flow benches, data coming from those was put into a different light when cars with ported heads that had increasingly higher c.f.m. numbers started to actually slow the cars down.

Unfortunately, high(er) flowing cylinder heads (to the exclusion of almost everything else) sell ported heads.

Flattening the short-turn often increases c.f.m. numbers but that is a prime area for air and fuel to separate if that is done; and the net result is a flame-out/fuel wash condition (lost power).

Analyzing the burn patterns on the piston top and the matching pattern (or lack thereof) on the combustion chamber is the best proof of all as to whether a ported head is working well or not.

So, as you know, there is QUANTITY of flow and there is QUALITY of flow. Some of the big-flow heads fall short in the power department; some, but of course not all, and those are the heads I'm interested in.

That is why I asked the original question with the tag of: "Proven Results."

Thanks

Ronnie

I think you proved your own answer as it questions what you search. One snowflake head is not an others ported black magic sanding tube. So, you ask someone without head work and you have to ask what circles back to polished surface X's experience porting as in years of porting heads do you understand flow and then it turns you around so???

Did you capture how no matter what you think is going on, do we have one number still sitting at BDC ask yourself yes or no the CFM stepped up in time = PERIOD I am an N/A.

I can prove there is a set of the pants move of speed I remove the air filter. I can prove I can remove PAIR and the pulse will cool down and slow the air bubble.

You have yet to see both the speed and the absolute volume will not change one bit. Yes, you sort of figured out how that fuel to the wall hangs up and the CV carb was that theory to slow that air down so the fuel would catch up.

Say the winter suck in the cylinder is 14.7 X's the Baro = SEA SPRAY? Digesthatheoryoureel'din!

WOT my problem is, I should have studied FI back in the 70's to exploit the VOES but who cares. No clearance on the bike so you could not push it like I want to see you push that bike as is now. If I were young I still could not if speed is relative and have a fast, decent running bike under me is a handful no matter the cc.

So, as that same number happens with a carb, so will it run the absolute copy the carb to FI. The problems are the eyes watching that fuel trim. The so and so, bend my fingers, quote/close/quote, the hot guy around town? The best can be beaten they roll that that sad ass map in a lag of a roll the $$$$ you may have schooled him or you were schooled at the wallet.

Oh, and you went right to the web and cleaned up the grid positions. How simple is that? I'd, download a manual? Are you watching me tune or am I pinging Slow aboutheory tuning. You, Ronnie, might be following the ladder turn not the bulb lighting off in Rome's head.

Rusty Dusty Barrel Roller kind of turned off the shop lights hear that guy come out tell me his 14 is a ripper with 6 wild who says left the ranch and lettuce mix his dressing is diapered his ass... Help me with my reality is YES OR NO, Romes is on the same page. Rook left the building is building another How's DAT!

Hub-

Thanks for your input.

I have been studying airflow since 1968 and although it may have appeared I was looking for specifics/technical information in this particular area, I'm not.

I do find your choice of words and sentence structure somewhat abstract; which makes an exchange of technical information more difficult than normal. I'm not trying to offend here. YOUR style is YOUR style..

I simply have no time to look at the shortcomings on the ZX-14 head and work with it until it is right.
I was looking for someone that has, and I'd purchase a working head from that individual.

That's all...

Competition CNC are the guys, I think, you wanna talk to.

I'm trying to give someone a hint about no shortcomings about porting a head, polishing a fairing for wind speed. What I am saying is that MORE does not happen about air entering the cylinder. All I have to do is read someone's abstract to that air flow; I can see you've been studying that as log on as I crashed a few years ago is found something I suck at and have embraced it.

It's pretty basic when I said there is no MORE air into that cylinder. The shortcoming is not to port the head at all if just clean up the spigots to the porting is how well the head comes from the factory. YOu just hand massage the portsome.

And it's sounds too solid a theory that if you hog out a port, you fill that void first, slow the air down. Slow, if that is a shortcoming, only snowflake will know; and that is your head now. So, from tuner to tuner burning out engine hours not a cheap tire needing replacing anyway. Oh and when all is sad and dumb, it lags a map made. What makes you think one more hot name is going to get you there if the only one who can is you doing the work.

Again, you are in the presents of 'Dr. Eyes'eel Burn' and what I see is you are telling me, (you know who) that stands in front of my fish market Odoor, say I pointed them down the street needing glass is and I sell fish only. When I wasss..

EELburn: That theory down and now I did enlarge your eye site. But did you extend the room you are filling? YOu are to read this chart before I remove that goatart tear sauce it seems is fogging your X to Y sight. There is no room extension as if you made more room for the big gear door! All you did was enter the room faster is your ass wont drag you stoop to that kind of face the moo sick.

No problem.

They are doing some good things...CLICK

Please keep us posted with your results.

Great,
Thanks again..

If instesd of doing the head,wouldn't it be better to remove the mesh on a stock filter,go to bigger throttle bodies,then maybe degree the cams and polish the exhaust side.Don't we need the turbulence on the intake

* Last updated by: darryle on 5/30/2011 @ 3:55 PM *

Air screen = More speed in.
Throttle bodies = A bigger amount of air waiting behind the intake valve is more speed in.
Degree cams = Intake signals a sooner opening. Exhaust signals all that air, then hold the power longer keep the exhaust closed a degree say more air speed in to exploit that speed.
Polish ports = Rough would be the intake to atomize the gas tumble or have the gas lick the wall and stay there? So, do you polish the intake so it speeds the air in faster, the gas just may wall itself as that phenom no matter the black magic. The exhaust is slowing down the faster event so would you not speed that ex port too?
The exhaust is the slower air flow so you swap for an open pipe for that one gulp to leave as fast as possible so the next won and the next WON more inches per lap becomes feet to the finish is that faster event when you had, same parts is parts.

06 14 made 168.0 in decent air with early M-10 exhaust.Blended bowls,Dotted the I's and crossed the T's on both sides of the head at flanges,Thin gasket,Brocks CT single,street trim made 197.3@12.9afr and 114.5 tq with 12.45 afr. Air might have been better after mods but not 30 hp.Just my results and all results may vary but should be close.

454, cams just dropped back in or cam slotted for degree work?

107 in 105 ex slotted Probably more hi rpm power @105 105 But I was after decent manners,And got them.Likes alot of fuel,even surges @ 14.5 afr lean cruise.Probably a manifold air Table issue.Less overlap= more map kp low rpm, Explains high tq #.I hope this helps, no BS here I just build alot of diff I Gas motors.Kinda interesting #s

When I'm ready, mines going to Carpenter. Coming back as a really bad-ass machine. :)

Interesting to say the least. I want to know how much BS it took to plant your pounds with all that work and the last thing something I've seen was Brock hitting close to book. Now, if he says he just pops on pipe and can capture that base number of the bike, with all that work you did, how come both are so close to book?

And the other interesting thing is seeing that cam nipple swing out of plane. It can't be a manifold air table issue if you haven't touched the signal, right? No kinked hose(s) from the throttle body plumbing, correct? So, I think I could count out that table. I mean, if that is a table, there you go is one 'variousignal' we don't need.

You messed with an 'ultimate' signal, I do believe. Base time is the air signal = IAP. The crank position = CPS signal.
And the MTS = Main Throttle Sensor opening are your base fi timers.

Here, I am now using your abstract to use manifold as your ultimate and I say it is a various. Here, I use what I think is happening inside the black box is that damn 'hall effect' on your cam move. Titty-titty-bang-bang is about a few degrees off said the base machine to the backup machine. Therefore, you made a wave of a change to trip the wave fandango, she bleeds limp rich/retard safe.

Say, yes, say no, it is the cam titty wave guding-ding.

When I'm ready, mines going to Carpenter. Coming back as a really bad-ass machine. :)

That's going to be a great day. Look forward to that report. I'm trying to get my brother to take his bike there.

Ya, if that day comes. Here I was told my VA claim had been sent to the rating board, and now I have another C&P Exam (seeing a specialist who will evaluate a specific aspect of the claim) scheduled this coming Tuesday.

The paranoid part of me (PTSD pushes it almost to being psychotic if untreated) is convinced they are just trying to find a way to get out of paying $50,000+ in back pay. The logical part of me, or should I say, the optimistic part of me is saying maybe it is not that at all.

It just doesn't make sense.

Anyway, back on topic, I want to have Carpenter go to Stage 3. Everything but a change of stroke. Between that, and a supercharger, she should be a real fire-breathing dragon.

I'm researching tire changers. LOL.
