Hey MN, the two back up gauges down low are Water and Volt. I added them because my stock gauges are not trustworthy. Actually i can see them fine while driving and they are always lit. But i would like to do something a little different. All a first draft and preparation for a first road trip.

I still haven't decided on seats, torn 930 donors still in there, probably going to source a set of manual 928 seats and have them done in pasha. Yes definitely.

And the center console gauge area will be redone in very nicely painted Gulf Blue/Orange aluminum metal with additional
Oil Temp & A/F Gauges angled slightly upward if possible.

The shift pattern sticker Bertrand made me was intended to be applied to painted metal...so it's a work in progress.

Yes, I think so Ken !

I'd like to make some changes and when ready I'll pm you for your opinion
if that is OK.

Signing off this thread for a while friends before i wear out my welcome.

Cheers Ken !

There is a spelling error on that lower door sticker, by the rear quarter panel.

Grammar error on the center console, too.

Since the topic of cooling and venting has come up before, here are links to a set of articles that I found listed on another forum. They talk specifically about measuring pressure differentials for cooling, and the positive benefits that improving them can have.

Part 1: http://www.autospeed.com/cms/article.html?&A=2159
Part 2: http://www.autospeed.com/cms/article.html?&A=2160
Part 3: http://www.autospeed.com/cms/article.html?&A=2162

Another interesting point that comes up repeatedly in many of his articles is that basic theories do not always make for good substitutes to testing and data gathering in complex systems. With a complex system, there may be a number of unexpected contributors that work to produce counterintuitive results.

I think i should have asked sooner..(Look below)

Do you mean Lite ? yes that could be changed and is my fault not Bertrands. Thanks

This is how Porsche wrote this on small bronze plaques in their IROC cars. Again my doing..This label will be affixed
to a body color metal panel (my old hood sheet metal !) with gauges next time you see it.

Thanks eroshi for contributing. But i like the clean hood too much now.

Since i am here,

Next modification/enhancement to the car..after discussing the process with Hans at Frenzy;

I was really happy with my RS on track at Summit Point. I came in late for the last two parade laps. I was last in line and once caught up was following a 997. What i noted while trying to hang with this modern 911 was that i could ! Especially noted this accelerating on the short straights. It was not pulling away that i could tell but a safe distance was kept at all times. This is entirely due to my cars very usable lower weight and ample torque.

So in an effort to make more gains through lightness I will try and build a lightweight fiberglass and lexan hatch for the car. It will have to be finished to the highest standard and look like a standard metal piece. I'll buy a second used hatch to make the multi part mold (top, underside and spoiler)
The current hatch is still heavy imo even losing the 25 lbs in glass.
I know of a US '83S in a nearby yard with S spoiler.

I think i should try and make a mold of a clean (OB style) hatch without spoiler or the wiper holes. Reinforcements will
need to be at hinge locations.

A mold in fiberglass of the S spoiler would also be very nice to make too and then join this to the fb hatch.
I could modify one for use on my car with wiper arm recess deleted and with the top/side edges slightly
more rounded to look correct without the S spoiler side pieces in place. I know this would
be correct aerodynamically as it would be the same profile Porsche designed.

Edit: added interior pics (sorry they are dark)

To Finish this concept:

To be more a realistic 928 Carrera RS Concept a stock dashboard would look best as well as installing the Glovebox lid.
924 Carrera GTS had the glovebox lid and the 928 lid is pretty light so it will go back in.

The Interior was to be finished bare bones like the '70s 911 Carrera RS pictured below and is.

The final seats i will use have not been decided on. Right now thw early manual 930 seats are only 2 pounds lighter than manual 928 seats.
I'd like something period correct but they must tilt forward for my young ones to pile in.
I am leaning toward the classic Corbeau RS which would drop another 30 lbs and bring the car
down to 2650 with a 1/4 tank.
Fun Car..

I was given a 951 intercooler to play with in my '83. I figure if na 944 racers use them for 5 BHP, it'll be good for about 7.5 BHP in my 928.
Old rule was for every - 10 F, 3% gain.

Also met with flussig Editor Pablo DeFerrari while doing some photography on Jason's 944 turbo with 325 BHP. see flussig link below, had a great time with Pablo. Great, great, guy.

I was pleased to find out my lightweight early 928 could hang on Jason's rear bumper all day long following him around NJ to look at old Porsches and back to his shop; R7 Racing and Restoration aka Maniac Racing.

You want to put a air-to-air intercooler on a naturally aspirated car and gain horsepower? If your intake air insn't pressurised and heated, what will an intercooler like this do?

Another great piece of writing by Pablo! His style has me laughing so much, I'm crying...I better check my "dungarees" also...

Jim D also has a way with words. I always thought Jim's true profession was being a writer. Love his comments at the end.

I'm so jealous of you talented "young" punks!

Shawn Stanford

That's seriously impressive, Matt! The 951 is not a slouch.

The Fixer

Yes this 951 is making 325 BHP according to Jason and weighs around 2900.
While followed him ith Pablo riding shotgun, I had no idea when Jason was going to put the pedal down but my 928 was able to stay with him no problem.
I was happily surprised.

Rick, Pablo is a pretty normal guy in person. I'll try an get him to come to PVGP this year to hang out a bit.

IMO, i was talking to Jason (951 owner and 944 mechanic and racer) he told me to take it and try it. He said na 944 racers use them for 5 BHP gains.
I will look into how effective these factory air-air intercoolers are soon.

Imo000

Matt, it doesn't make any sense how that intercooler would do anything to a N/A car. It is already pulling in ambient air, that intercooler is supposed to cool it even more? I can understand how that could be possible. You get the intake to pull air from infront of the radiator or outside of the engine bay and that's as cold as the air can possibly be. How do the 944 guys install these?

The Fixer

Imo000,

The more i thought about it today the more i agree with you.. But Jason is a very knowledgeable 944/951 mechanic and racer, I know he's not making it up that 944 racer do this.

But I just can't imagine there is any gain at all that wouldn't offset
the added weight and air restriction

These charge air coolers are factory mounted right up front behind the bumper cover and just below the hood on a 951. But if ambient air flows through it how does it reduce air temps. It should not.

I decided to test and draw air through it with my mouth and the air did feel very cold in mild 60 F temps outside.

Still don't see this mattering because even if you improved the engine bay ducting and airbox sealing, by the time the air got to the cylinder it would be warmed to about the same temp imo. Not seeing how this could work under my hood.

Post a pic of you sucking the intercooler.
