Fifth gear

!! Nice!!

It didn't feel fast because you were in the confines of a well built German  car. 

 

Figure out the 'model number' of the 912 transmission and I bet we can rundown the gear ratios.

 

I did find this:

http://www.912registry.org/restore/trans_table.htm

 

So, if it's a 912e, then it's a 1976. Your tans number should start with: 5060001-

Your ratios would be:

11:35
18:33

23:29

26:25

29:21

 

With a 7.3:1 ring and pinion. 

 

Thank you. Please drive through.

Glad to hear you got the "pointy pumpkin" out to stretch her legs. It didn't seem fast because you were euphoric.

So, what color is the car?  I'm intrigued.

I'm one of those odd ducks who loves data about limited edition cars.

 

Great information Ted....Many thanks.

Now I just have to 'math' what 60 or 70 mph should be with a 29:21 fifth.

 

The paint code is 415 B6. I don't see it listed though

But Gallo coined it "Pointy Pumpkin" which I initially thought hinged on being cartoonish...but now I'm pleased with that visual description! Thanks Al.

 

That 60 mile loop this morning was a delight.

Driving city streets doesn't give you good 'seat of the pants' feedback on cruising performance...not a squeak, not a rattle, not a burp. I'm surprised that it still had decent passing torque in fifth.

Simply hungered down and smoooth...and with roll up windows, what could be better!  

Carl,

 

Paint code is 415, Sepia brown.  I think the B6 reference is to your Bilstein shocks.

Hummm, sepia touch up paint on a vivid orange 'Pointy Pumpkin' won't do!

 

The Superior Automotive Paint Supply Company of Murray Utah has mislabeled their "Paint Touch Up Kit" that was provided to the PO...and passed on to me.     

Carl, no disrespect intended. Now that you know she zooms like she's supposed to on the highway, zoom out this way. Love to see it in person.

Hey Carl, is that 5 speed a 'dog leg'?

 

If I can get enough energy to go down to my main frame, I'll post some pix of Carl's 911E. I've only seen pix myself, but it appears to be a beauty. Carl and I may be taking and old farts road trip to Vermont in the future.

 

Here's Carl's pride and joy:

More of Carl's 912E:

Carl,

 

You got that 912 at the right time. The market for 912's is really on the rise and the car is drop dead gorgeous. 

 

I would guess that your car had a respray. That's more Signal yellow than Sepia Brown. 

 

You should register on the 912 site.

    Ted...I was fortunate.

A very timely purchase that I had no intention of  looking for.

 

    I was up early one morning (as I am this morning!) searching TheSamba for odds and ends of parts to hoard for an eventual Suby conversion for the VS...and there was this 912e out of Utah with a veeery attractive asking price.

    BANG! it hit me that, because I'm a mechanical dunce, the VS would be up on jack stands for a long time. But here was something I could drive in the interim to keep my flagging ego inflated...and I could always get my money back when the VS was back on the road.

    I happened to be the FIRST IN LINE offering the asking price.

After the deal was cemented the PO told be that there was seven in line behind me, with cash in hand, chomping at the bit.

   I actually didn't know at the time what a 912e was. From bumper to bumper it's a 911SC that was pulled off the Stuttgart production line and fitted with a 914 Type4 as a one year ('76) stop gap entry level for the American market between the discontinued 914 and the delayed entry of the 924.

    Jowdy told me that although it didn't have the scorching performance of a 911 they were more agile, and pleasurable, negotiating traffic, while still being capable of comfortable speedy long distance touring....and he was right.

 

    It is a repaint from the original green. I guess that devalues it to some extent. 

And I think that I am 'registered' with the 912 people, although their web site is so complicated and confusing (compared to SOC) that I haven't found an easy way to navigate it.   

    

Yes, I did a typo up above, it's a 912E.

"E" for "einspritzung," I believe?

Hey BTW I do not understand the gear ratio formatting above so I converted to "normal" notation. But I got to the R&P and was confused again.

 

So, if it's a 912e, then it's a 1976. Your tans number should start with: 5060001-

Your ratios would be:

11:35

18:33

23:29

26:25

29:21

 

With a 7.3:1 ring and pinion. 

This works out to

 

3.18 1st

1.83 2nd

1.26 3rd

0.96 4th

0.72 fifth

 

Which look very much in line with the kinds of ratios we see in Type 1 transmissions. The Overdrive looks a little deep, but OK.

 

Then you get to the R&P, which on our cars is in the 3.88-1 or 4.1-1 range

 

A 7.3-1 rear gear ratio is crazy drag-racing tall. It's most of double the normal VW ratio, meaning the engine would be turning twice the RPMs in any given "normal" trans gear to make the car go the same speed. It would more than negate the effect of the extra deep overdrive 5th, making it equivalent to about 3rd gear in a Bug.

 

Purported Porsche 7.2 5th gear x 7.3 r&p=5.28

 

Look here.

 

3rd gear in a Bug is 1.26 (just like the Porsche ratio noted above!) and the late final is like 3.88

 

1.26 x 3.88=4.88

 

With the earlier 4.125 R&P it’s 5.19. Basically the same ratio as the claimed Porsche final drive.

 

I do not know why I care...but I think there is an error here, either in the claimed Porsche gear ratios or in my brain, where math is very, very hard.

 

Ed, I think it is 7 pinion teeth to 31 ring which is a 4.42:1 ratio.

 

Carl, if you head west, young man, I'd love to see/ride in that car. SWEET ride!

I'll carry your bags, Carl.....

This is the Porsche Sepia color - kind of a dog poop brown. Since sticker says that -that must have been original factory color. Yours is definitely Signal Orange now.

 

 

 

"Signal Orange", huh?

 

Well, Gallo coined it "Pumpkin" and out of respect for his opinion I'm sticking with that color description...

Danny: Yeah. Typo. 4.42 would make sense. So would 3.70.

 

 

Personally, I like the "Pumpkin Orange".  Way better than the Dog Poop Brown just above this post.

 

Good call by the Beach Comber, indeed.

 

Pumpkin Orange sure beats the heck out of some of those hideous "Earth Tones" that Porsche thrust on us in the 1970's, doesn't it?

 

And who can forget that beautiful, wave-effect, "Checkered Flag" motif they ran one year inside of the 924/944s??  Went well with the dash knobs that fell off and the dash top pad that cracked in the sun.

 

But, that aside......they were wonderful "Driver's" cars, weren't they!

 

Carl:  There are several 912's in the TYP356ne group, so you're not alone (one guy has a 912e like yours, plus a Vintage Speedster!)  I also know that there is a pretty active PCA group in Connecticut, but I believe a lot of their activity is closer to Hartford and along the coast, but there is a LOT of activity centered around Lime Rock, just North of you.  If you want to get involved with them, you may contact Tom Thalman ( tthalmann@verizon.net ) who is quite active in the CT PCA group and a real nice guy.  He coordinated a recent run, starting in Southwestern Rhode Island and over to Pomfret, CT and then around the valley near Pomfret/Putnam and invited my 356 club to join them.  They had everything from replicas real 356's to Boxsters to 911/944-series to a couple of Lotus Elites.  I got the impression from the lunch group that they are involved in get-togethers all over the state throughout the year.

 

Good luck - I'm sure you'll find some other Porsche folks nearby just as nutty about them as you (and I) are.

Ed, early 915s were 7:31(4.42) r & p and the later ones were 8:31(3.875 or 3.88)

Thank you sir. Mystery solved.

 

Eats, shoots and: leaves

Trust me, Ed.....Not a lot of people on here have read that book!

Grammar is important.  Makes the difference between "Feeling you're nuts" & "Feeling your nuts."

Let's eat, Grandma!

 

Let's eat Grandma!

 

 

Punctuation - it matters.

What's the difference between helping Uncle Jack off a horse and helping uncle jack off a horse?

None! Both are referred to as 'The Scary Uncle' maneuver! 

 

Sometimes also known as the 'One-legged Alcatraz'. 

And talking about Alcatraz....who was Robert Stroud, eh ?

 

This is a yes or no type of question. Try to get out of this one.....have you ever blown a c??k as nice as mine ?   :-)

 

Good spelling is helpful, good grammar is great, punctuation does matter, inflection is often required.... All of the above is normally appreciated and respected...unless you don't / aren't willing to understand or basically  DGASHYT.

 

I taught Effective Communication Skills years ago and got paid for it. Now I just weep....:-)   and drive Speedsters to kill the pain...

David, I believe Robert Stroud was the Birdman of Alcatraz. Related?

 

Jimbo, what the hell is a "One-legged Alcatraz"? I guess I've led a sheltered life compared to you SoCal dudes.  I'll try to catch up....and I thought I was the scarey uncle.....

But helping Uncle Al off a horse is no fun at all 

Nothing I can prove, but I've been accused of the probability more than once. I admit to the curiosity though hence this pic.

 

Second pic is a nice one up in the hills of SF with Francine figuring where we head next. Only about 3,500 miles to Carlisle....somehow we did way more than that. man those were the days...2012

 

Name the place where these pics are on the wall and get a free six pack at Carlisle 2015...

^ El Rancho! 

Bingo, Jimbo....hope to see you soon, Amigo !!
