Thanks for asking Helio - car's still on stands for header install. Got the valve adjustment done / accumulator installed tonight, tomorrow I remove the ex-man studs - HOPEFULLY!

Then it's install time and will know the results of my control pressure regulator shimming, etc. Damn I hope to be 'there' by Fri - we'll see.

Smurf - I'll have to look and see which Bosch WB02 I have, thanks for the suggestion.

Sorry Helio... in my 2am haze I neglected to answer your port color question.

All six were evenly sooty... I've been running pig rich for awhile now. I was relieved tho to see them all black after seeing so many here with 2&5 white like yours.

Eeeeek, no thanks.

Actually, the headers I got from a member here had slight whitening to either 2, 5, or both IIRC.

btw - just saw the pic you posted of your car (opposite lock @ WOT) in the thread about 'which cyl's run lean'... that thing's friggin COOL! Really dig it!

While the 993'ing to the nose of a cherished '76 is somewhat sacrilege 8-), I'm sure you had your reasons and the end result looks fantastic! Dig the GT2 flares esp!

Very cool, more pics!

Where you located?

VERY nicely executed, really dig it all!

Heh, I just installed those front Fosgate speakers a few weeks ago 8-)

More pics!!! Ah, 911S... def less a sacrilige issue than forward-dating a '76 930. Love what you've done...

FWIW mine idles at similar AFrs. The engine is noticeably happy around 12-12.5. If I go higher than this, splashy, erratic exhaust, and low throttle AFRs go 15+ and car coughs badly. I need these afrs to be below 14 if the car is to move off low throttle without major hiccups. And my AFR is calibrated. I dont think this is unusual, especially if the engine is not dead fresh.
Basically, I just follow the engine. If it is unhappy at a certain number, I move on rahter than try and convince it that a certain number is good for it.

*update*

Got the POS back on the road Friday (headers / valve adj / accumulator / control pressure shim'd to 7.0 / Lambda delete). Running fantastic!

I had to dial my idle AFR to 11.1 or so (sometimes it's 11.0 sometimes it's 11.2) in order to achieve a max of 15.5 on off-throttle cruise (2,800 in 4th, no boost). Most of the time the slightest bit of throttle will see it more like 14.7-15.0.

Under boost it's great - again - until 5,600 or so. Climbs to 12.5, 6k sees 13.0.

Again, the car seems to run really really well - very happy idle, not too stinky, no off throttle / transition 'stuttering', etc.

I still have to test my flow rates - maybe I've got weak pump(s)? 55k tho, doubt that (they volt-tested fine). I also still have to hit a sniffer station to confirm my WBO2 readings.

Questions until then:

Is it OK to cruise @ 15.0-15.5 @ zero boost / throttle? Or should I dial my idle back to 10.7 to get <15's? I got 17mpg on my 300mi ride home from Mt. Washington Sunday, which included 'some' light cruising (traffic) but mostly 100-115 cruising w/ many WOT bursts to 125+. Not too shabby 8-).

Is it OK to see 12.5 for brief stints, and 13 for even briefererer stints? Meaning, I rarely track it and heck rarely see the need to shift past 5500 (still running 3LDZ hairdryer which wheezes beyond 5500).

But there are the few street occassions where I'm goosing it past someone or to put someone on their place (heh heh) where I'll hit 6k and quickly shift. The time spent @ 12.5-13 getting from 5500-6k isn't but a few seconds.

So, is that OK - or still huge no-no? I'm OK keeping it <5500 if so, but it'd be comforting to get your insight on the occassional dalliance beyond 8-).

Thanks guys. Knock wood tho, car's running fookin awesome - best in the 4yrs I've had it!

Hello

As to your AFR beyound 5500, 12.5 to 13 is in the stock range. With a stock setup , there is no real need to increase the fuelling in this upper range.

11 at iddle sounds a little fat while 15.5 on cruise seems a little high. World is made of compromise.

Sometime , instant reading of AFR gauge can fool you... curves and/ or average should be done in order to get better idea.

like he said on boost looks great , I think your idbutle CO should be 1.5% leaner side 14afr
as rich 4%CO 12.8afr max , if you have 964 cams like do I run 2.6% CO =13.54 Arf I get 14afr on cruise ,

If its working for you , great

thanks Thierry / Helio

So I guess my question is - should I lean out my idle and then adj my WUR to richen up cruise (which will go north of 16 upon leaning the idle)? I see suggetions of this sort in the other AFR thread that's running right now, but no mention of it here?

I'd really like to eeek out some more MPG's out of this pig - I got 17mpg on a 300mi roadtrip which included a lot of WOT / trip-digit time, yet only 13mpg during a week of commuting 26mi each way mostly highway and only 'some' WOT. Sucks.

Those 'on boost' figures only look good if you KNOW you have exact same fuel delivery to each cylinder. Some would say to go a little further and have a smidge more on 2 and 5 too for extra safety. Have you gone through and checked this? If not then you may be too lean on one or more and your 'accumulated' afr is misleading..... Running very low 12's or mid/high 11's on boost adds safety until you've balanced the fuel to each injector, and checked them for a nice spray pattern. problem is they varnish over time, so without checking you simply won't know
