Amber fan shroud for 6 cyl Options

I have to have help to walk upright!

So THAT's what Clayton was doing when I walked into your hotel room that day... helping you walk upright. Now I get it... (IMG:style_emoticons/default/sheeplove.gif)

Red is the color of choice as it was supposedly fitted to the "S" engines.

Red is the 911 crowd's "Type R" sticker.

Many 911's have been made faster by the judicious application of rattle-can red...

Mine is red.

But the previous owner did use "S" cams when he built the motor (among other improvements).

I saw a carbon fiber one at Hershey a few years back... now there's your bling!

This is occasionally possible but you do have to be careful, because it's one of the famous benchracer bullshit lines.

It's hard to 'just' put in S cams (unless we are talking CIS-era S, which are pretty soft, S or not...) because in the early cars, S cams will make valves too friendly with pistons. The big valve relief pockets cut onto 911S pistons are not there to lower compression ;-)

I have seen those. A guy told me he'd sell me one for $1,000 (IMG:style_emoticons/default/blink.gif) . I'll pass.

I tend to believe him. He turned a 2.4 MFI "T" motor into a screamer. It dyno'ed 190 at the wheels.

Mine's red when it's angry.....

Why not sand through the gelcoat and partway into the fiberglass of the stock one, and then add a layer of fiberglass and epoxy? It would probably be stronger than stock, all airflow patters (inside) would be stock, and it would be a natural fiberglass color on the outside. It would even have a hand built look, like you might find on a race car or prototype. (hand laid fiberglass is generally considered superior, especially when intended to be left unpainted)

Series900 is the best I've seen.

That seems to be the consensus of what I've heard.

Series900@nhvt.net The contact is Damon. I believe he's the owner.

agreed,

the S cams need S pistons, which need S cylinders...
suddenly its an S motor in total...
Its usually more than just changing the cams

it can absolutely be done
but its more than "just cams"

Here's the exception I referenced...

Near as I can tell (for obvious reasons, performance cam houses do not show the CIS 911S among their offerings...) the 1975 911S differed from the "911" cams only in timing.

From '911 Story' ---

CODE

i open/close:       2,7           2,7S
                    22ºbt/58ºab     16ºbt/72ºab
e open/close:       52ºbb/16ºat     47ºbb/21ºat

identical exhaust duration, in fact, but with timing shifted relative to the intake.

I have not been able to find lift specs, and this is not my research project.

But here's a case where there's no real difference between S and non-S in lift. I'd further guess but can't research this morning that a '75 2,7S has less lift than a 2,0S cam.

I'm not in touch with the guy, so I don't have a way of asking what "everything" he did to the motor to build it up was. But the dyno doesn't lie. Obviously he did more than "just cams" to get to 190 at the wheels.

Yes - we're agreeing with you ;-)

What we're actually discussing in this thread (aside from the actual stated topic) is the murky world of 'fresh rebuild' engines for sale.

A bit of rattle-can red and suddenly you have a 911S engine. or an engine 'built to 911S specs.' or 'built with 911S parts.' I think I'd almost rather have a basket case or a tired virgin core. (instead I have a tired Motor Meister rebuild of a '75S' with - yes - a red fan shroud. I have no doubt many surprises await... But I knew I was buying a core and the price was right...)

You see this all the time - engines described as "2,7RS" when all it really means is they found some 90mm Mahle P&C's. No MFI, no RS dizzy...

The same thing happens in the T-IV world. We've seen many cases of "fresh 2,0 engine" being built with 1,7 heads and 2,0 bus pistons.

Some phrases just wave red flags.

I'm sure your engine is happy and healthy and I'm glad you have the dyno numbers that back it up.

[zymurgist]

Yes - we're agreeing with you ;-)

No worries! (IMG:style_emoticons/default/beerchug.gif)

I hear you... I have been thinking about buying a tired engine that needs a rebuild and building it for the 911... that way, when I decide to sell the car, I'll pull its current engine and keep it for a 914 project "to be designated later."

I did think about the carbon fiber shroud when I saw it at Hershey... for about 30 seconds. Then I put the bong down and went back to rummaging through the body fiberglass.
