60 may suck but knowing Greg doesn't!

Sieg what's the bushing looking thing next to the sway bar mount?

:EmoteClueless:
Dan

Agreed, the entertainment value is off the charts and to date he hasn't got me throw in jail. :D

The bushing 'thingy' is classified as a sleeve and clamp in the factory assembly manual. :thumbsup:

Few basics lately........the #3 plug cap started arcing to the header tube and I decided it was time to install an AEM A/F gauge in the system to see how close my seat of the pants carb tuning had been.

The sensor was the easy part. Locating the gauge involve a little more thought and fabrication......

Nicely played.


I've never heard of the ceramic boots before. That's an awesome solution to a problem a lot of guys have!

So here's the thing I've discovered about AF for what it's worth. "It all depends". LOL

It all depends on if you're just trying to make some artificial number - versus giving the motor what it wants. Idle still should be tuned for highest vacuum reading possible and highest RPM's. When the motor is getting the fuel it needs it will respond. End of story. Whatever that "number is A/F wise" is what it is. I've seen lots of people make the mistake (more with EFI) trying to "make" the car run on some A/F number someone told them. With all these motors being different combos - there isn't a magic number... because there's so many other factors that influence the combustion process.

Where these A/F meters are helpful (IMHO) is jetting on the big end of things. We used to use timing slips and try to tune for MPH... which is what told us if we were going the right way (OR NOT!). Now a guy could go out and check for lean or fat condition by making a WOT pull on the freeway and a quick glance at the meter will give him the info. Sweet.

The harder part I think would be trying to tune for freeway cruising... with a carb you just don't have the ability to lean it out in an area of throttle / load like you can with EFI.

Thank you.

Those ceramic caps are priceless! Reading the reviews multiple people were complaining about the cost.......$22 shipped via Amazon prime. WTF! Consider the alternative cures people. :lol:

Totally agree on "it all depends." I've always tuned by feel and plug/exhaust color because that's all I've had and always try to error on the rich side.....as a kid my 2 stroke motorcycles taught me the value in erroring rich. :D

I was very happy to see the idle and cruise was in the ballpark.

It also showed my front float level is low as it goes lean off the chart under braking. Quick bump up on the level and possibly install the jet extensions will cure that.

Regarding tuning for cruise, that will require some thought, though with the Holley Ultra HP it is very tunable. idle & high speed air correction jets, pump cam profiles, pump shooters, power valves, and tunable metering blocks that allow power valve/idle/emulsion fine tuning.

What I haven't found is a good chart that shows how all the circuits overlap through the throttle range.

This is the chart I always referenced to dial in my bikes and a similar chart for Holley carbs would help my visual brain immensely.

Here's a pump cam profile chart that looks somewhat like EFI tuning......LOL

Nice looking gauge Sieg. That's an upgrade I'm looking forward to getting to. Definitely a great tuning tool. What kind of readings are you getting in the upper rpm range

Thanks. I'm looking forward to playing with it. Only had a chance for a quick loop (6-7 miles) last night and not enough open road to really exploit 3rd or 4th gear. In 3rd around 4-5K the richest I saw was 10.8-11.4.......I think. A GoPro would be real handy to record data.

A wise old tuner once told me "If you ain't melting pistons or fouling the plugs....You're GOOD to go"

Awesome gauge mount and fab work Siegmunster :RunninDog:

nice work seegie

Brilliant quote right there! LOL


I used to tell guys -- Lean for a day.... Rich for life.... and most of 'em would just look at me with their eyes crossed. My Brother in Law found out what running a blower, and lean, means.

Thanks Vinnie! :D

Word Jerdawgy!

Thanks

I never holed a piston on any of my 2-strokes but I fouled a few plugs. Frugality is a valuable tuning tool. :D

It was nice to see the initial gauge readings were all on the rich side with the exception of the front float level inducing a lean. Now I can get a little more risque with my tuning. :unibrow:

The rain season has commenced in the Pacific Northwet so test and tune opportunities will most likely be few and far between. :bur2:

You can apply that to Investing102 also....great quote

Sieg, do you get that thing out on the track at all? And the GoPro would be a second set of eyes? stayin on the pavement is kinda important if your into that sorta thing:walkingdog:

Super nice tight work BTW, love you car as you know....

Thanks.

To date it's never been tracked.......not even at the local school which I can't say that about a few of my dirt bikes back in the day. :D

Did you use to work for a circus? Great welding Mr. Contortionist.

I found an article that helped me out a LOT!
http://www.rodauthority.com/tech-sto...y-carburetors/

So I read this article a few times and drove the car to get a feel for the transition points then started making changes ONE at a time and test driving.

My goals were to get idle in the 13.5-14.0 range, cruise in the 13.8 - 15.3 range, and WOT in the 12-13 range. Before adjustments I was seeing 12.5-13.4 idle, 12-13 cruise, and 10.8-11.5 WOT.

First change on the Holley Ultra HP 650 was an idle air bypass adjustment Which gained a few 1/10ths at idle. I have to add now that I have this a/f system.......I should have bought it a long time ago. It is so nice to make a 1/16th or 1/8th turn adjustment and see immediate results.

Second: changed the orange accel pump cams back to the lean stock pink cams. Picked up a couple 1/10ths

Third: changed the main jets from what I knew were rich 72's back to 70's (carb came with 70's) and another positive result but still rich in the cruise mode.

Fourth: changed the primary mains to 68's, another gain, still rich.

Fifth: changed to idle air bleeds to 73's from stock 70's, that got it in the ballpark of 13.5-15.0 in the 2,00-2,400 rpm cruise. In 2nd and 3rd gear at 3K it will go 15-15.9 which bothers me a little, but it's only for a second or two and the gauge spikes all over the place so trying to nail the average is a little tough without data acquisition.

Sixth: changed the accel pump cams from stock pink to red (slightly leaner than orange) as by leaning the overall circuit it developed a hollow off idle throttle response and a little stumble on light clutch engagement. The red cams were a big improvement.

End result is idle 13.5-13.8, cruise 13.8-15, WOT 11.7-12.5. There appears to be some very brief spikes depending on throttle application input speed and rpm but it's much closer and it runs very good overall. Never a hint of pinging or detonation. The Ultra HP has adjustable metering blocks so further fine tuning can be accomplished via idle restriction circuits, power valve circuit, and emulsion circuits via jets in the metering block.

FWIW - It's damn tough to monitor a sensitive gauge and while hammer the throttle and shifting gears. :sieg: :lol:

It really is the simple things in life that bring the greatest pleasure. :D

More pro-tinkering toys to install now that the rains have come to the Pacific Northwet.

After SEMA a front suspension tune up and installation of Dynalite rears discs will commence once I figure out the best e-brake cable connection option.

It's all in the details Scott! It's always (well sometimes anyways...:confused18: ) fun fine tuning and seeing the results. Good job! In regards to the E-Brake cables - look at Control Cables. They have a multitude of options and great to work with. I just bought all my stuff from them. Talk with Greg.
http://www.controlcables.com/

Thanks Brent, I followed that link when you posted it a while back, didn't have a personal contact though, I'll give Greg a call and see if we can create a solution for my application. :thumbsup:

I love it when the :ups: or white truck shows up!!

All the UPS presents are installed!

Next!

Niceeeeeeeeeee!!!! Whats next!?

Mario I'll reserve comment until after SEMA. :D

A torque wrench would come in handy.... :slingshot:

:smiley_smack:

It's getting worse..........

you like country right?
 

wrote a song about it, like to hear it, here it goes....

Killin it tonight aren't ya Vinnie! LOL

Today was pretty much the epic fail of my wrenching career.

Good news is I'm alive to pay for it. :bang:

its all right. pick yourself up and learn from it. everyone is ok.

What happened?? Glad your still with us :headscratch: :innocent:

Let just leave it at it started with this:

Other than the quarter panel damage it's all repaired as of 10 minutes ago.....:sieg:

Glad to hear your OK, Now spill the beans on what happened! :twak:

How about SEMA over a couple frosties? I can probably stretch the story to 3 or 4 frosties. :unibrow:

Sounds like a plan :thankyou:

I'll have to wait for the recap when you guys get back.....

I lost a wheel on my truck..........imagine all the scenarios........none of them are good. :D

Yesterday Norwood joined some elite company around here in the PT Jackstand Class.

http://photos.smugmug.com/photos/i-J...-J98TzFJ-L.jpg

46 years ago these weren't bad brakes.........but they are still exceptional emergency brakes. :)

http://photos.smugmug.com/photos/i-4...-4SzCgFS-L.jpg

But these are a little better.........

http://photos.smugmug.com/photos/i-7...7VJ3Z69-XL.jpg

Today I hope to get all the details figured out and order the parts tonight.

http://photos.smugmug.com/photos/i-2...2qdG8Zd-XL.jpg

First I'll get backing plates mounted, reinstall the axles, align the calipers with the rotors, check wheel clearance, and finalize e-brake cable lengths so I can order new cables from http://www.controlcables.com/

Then I need to decide how I'll transition and mount the factory brake line on the rear end housing to accept the stainless flex lines. Leaning toward the Wilwood kit 220-7056 http://www.wilwood.com/LineKits/Line...temno=220-7056 I'm thinking I'll just fab and weld a tab on the axle tube to capture the -3 to 3/8-24 IF fitting and be done with it.

After that I'll get the new residual valve installed and work on refinishing the show side of the Wilwood Dynalite calipers.

Sieg,
Norwood is looking good. For some reason I have never looked into your thread , I read the first four pages and am intrigued to keep going but when I saw I had another 180 pages to go I realized I would be here for a few days, I skipped to the end so I could see what I am getting into and tell you I like your story.
Talk again once I catch up!

While your at it, you might as well switch over to Ford ends on that 12 bolt or get Poppa Weld to spring for a 9"

too bad no one makes a reliable bolt on c clip eliminator
