What the "L", Supertec 2.8

[PFM]

Henry,

We may not always see eye to eye but I must salute the obvious first class nature of your builds! The motors you and your team put together look to be beyond first class.

Best regards,

PFM

I'm not sure who you are so I can't comment on "we may not see eye to eye" but thank you for the kind words. We take a great deal of pride in what we do, so comments like yours mean a lot.

I'm sure this is obvious to others, but why does that case and 4/5 bearing mod only done to that bearing and not all of them?

And, as always, stunning work there Henry - the marriage of art and engineering!

The crank ordinarily fills from each end (#1 and #8 main bearing) making the number 2 and 5 rod bearings the last to get oil. Feeding the crank oil from the middle is a way to increase the oil available to rods number 2 and 5. This is more about flow than pressure.
In the past this modification was only performed on race engines but since we do this work in house it seemed reasonable to do it to every engine we build.

Uhhhhhhh this job is good and all is very beautiful !!

Think you for share...........

As long as your valve lift is less than Eibach's published pressure @ full lift number and you can live with those numbers, you're good to go.
If you desire higher full lift (over the nose) pressure then calculating spring height becomes an more challenging endeavor.
When we first encountered these springs we were skeptical so we invested time and resources into testing the validity of Eibach's claimed number. At this point we are satisfied that they (Eibach) did their homework.
Of course for all of you "engineer types" that struggle with believing an "old dog" you are more than welcome to do your own homework.

Thanks for the detailed feedback. I figured since the 120/104 has a lift less than the the max lift Eibach states for the given installed height, I should be OK like you said. I'm not planning on going over 8000 unless I miss an upshift and zing the revs a bit. If I select the wrong gear altogether? Well that's a different story.......

Also appreciate you doing the legwork to test the springs. Given what other hi po 911 springs & retainers are sold for, it's really easy to question the Eibachs seeming to be too good to be true.

Somebody's gonna get a mighty fine sports car when all this comes together. If possible, ask him to share one he puts that beautiful motor into the SWT!

Thanks Dave, how's your little Porsche running?

This engine is being shipped to KS. so I'll have no control over the install but I'll ask for pictures.

Funny you should ask.

My father never had a Porsche, but he "heard" they broke down a lot and suggested I stay away. My brother owned a 912 after working as a VW engine rebuilder in the early 70's. He told me to stay away from 911's as they required special tools (true) and would cost a fortune to maintain.

To answer your question, it just runs and runs. I drive it at least once a week if not more, it never fails to start and it never has any issues taking me down the freeway at 80 or a back road with plenty of punch. Between Porsche's engineering, the MFI (no carbs to adjust) and your rebuild I am always amazed that a car this old can be every bit as reliable as my boring 21st Century Toyota.

Of course, that doesn't keep me from dreaming about owning a coupe with an engine like that SS 2.8!!

A 2.8 SS like this?
Just remember Dave, we can build you what you want "no matter how much it costs".

Henry,

You should develop and market a "keyboard drool catcher" so that folks can be better prepared for your online builds ...

Thanks for sharing and continuing to do the nameplate proud !

Although that is a gorgeous engine, I am surprised that given the current state of early 911 prices, that someone would take a number matching engine, and have this done to it. Seems that it would actually devalue the car. Why not take a later engine and do this to it, keeping the original stock? As always, it is the owners choice, but it doesn't really seem there is any value to using the original crankcase in this way.

In any case, if I could afford it, I would put that engine in the middle of my living room as a piece of art.

The "value" of a car is based on the criteria placed on it by the owner. Build what you want and enjoy it. If you're building a car to suit the requirements of some arbitrary standard set by "experts" I think you should "step away from the vehicle". Built it the way you want and drive it. ENJOY.

Well said Henry!

Cheers,

As for me, while my car is "all stock" on the outside, inside (the engine) Henry made all kinds of mods. New higher compression pistons, case mods for lubrication, more aggressive cams, and additional cooling, all using the stock, numbers-matching magnesium case. And if I wasn't forthcoming about it, no one would be the wiser.

This lets me have more fun with a stock, survivor car without the guilt that comes from destroying it (like so many did in the 80's - 90's). And if I could afford a 2.8SS, and if my 44 year old case could take it, I do it in a heartbeat!!!

My $.02 anyways!

Henry, any updates on this build? More pics please!

[Henry Schmidt]

Strangely enough, this build is back in front of the line.
Today we start fitting the Amber shroud kit. This sweet kit is coming from 911 Vintage Parts 760-731-4911

Very nice, Henry!
