Knackered old Porsche with loads of miles - 996 content

[geraintthomas]

Just incredible. Love how it literally seems invincible. You've built a monster!

Quick question, and it may have been answered - have you put this on a dyno to check how much power it's pushing out compared to what it was like new? Just out of curiosity sake, as I saw someone on YouTube take his 243,000 911 996 to a dyno and it pushed out identical BHP figures to what it was like when new. Wondered if yours would be any different

Not really no, I like the fact it looks like a very slightly lower standard car - that's a big plus to me really and as the split rims crack tested up fine when they were rebuilt a while back they have plenty of life left in them at this point. Plus I put quite a lot of work into fitting the brakes under them so it'd be a shame to waste that

With regards panels as it stands now the lights, front wings and bonnet are all pence off e-bay in the right colour as Boxster bits are a straight fit as well as 996 parts. Likewise for the rad ducts and various other front end bits. The rear bumper is also cheap as chips in the correct colour as it is standard across all the first generation 996. As it's very likely to get bumped, banged and knocked purely because it's out and about so much I'd rather keep it all easily and cheaply replaceable. My target was always to get it to 996 GT3 weight and we've pretty much managed that with no major compromises/expensive bits or uncomfortable lightweight seats

Fair points, well made. I agree that OEM+ is a good look, especially when you know that under the skin things are substantially more interesting!

Weirdly, a GT3 is heavier than a C2

Finally my fan on/off temps are set lower than a standard car, the fans go immediately to high speed when activated and constantly run at low speed below 60KPH to provide additional airflow to the rads at slow speeds.
!

A manual fan switch (incl. 2 stages) + Oil temperature gauge should have been standard/essential items in both 996 & 986, imho.

Agreed, particularly the oil temp. I'd rather have had that than the battery gauge.

The way to cheat is to know what your oil pressure normally is at idle when fully warm (mine sits about 1.5), so you can gauge how warm the engine is by the oil pressure.

Similarly, on a turbo, you can tell by trying to check the oil level (digitally). If it won't let you, it's not warm enough.

These are mental value! I'm very close to finishing the strip down in my mx5 and starting the hunt for an early 996 as per your advice PPBB

So, at the risk of someone else snapping it up, what wrong with this one?

Silly price... check
1 owner.... check
Full history.... check

Even some form of dealer bork protection for what it's worth.

Very patchy MOT history seems a touch strange (private plate or Irish holiday perhaps) but if it is as straight as it looks then it might be a good base for a (4WD convertible) project!

How do you reduce the fan operating temps ?

You can us an aftermarket fan controller or have a mapper change the fan on/off temps in the ECU.

Well the shell is heavier than the C2 shell as it's the C4 shell. Brakes are bigger and heavier, motor is heavier etc. etc. they did well to get it as close as they did to the C2 weight

Awesome, ill look at an ecu mapper. Sorry, last question i promise, what fan controller would you recommend.

Pok.

Great thread! Beats any book hands down.

I've cheated somewhat as the Evo5 logger in the nose reads the coolant temp and vehicle speed from OBD2 and then pulls the fan relays down accordingly but you do have a point

You just hit the algorithm of the century

If x < 20 and y>95 than 1 else 2
(X: Speed, Y: Coolant temp, 1 & 2 fan stages)

As my suspicion on all sorts of fan relays out there, I would still wish to put a cute switch on the dash though - similar to 993 oil cooler fan-

Erm, it's missing a roof?

True enough, but i really enjoy wind in the hair motoring, and as it's a toy that's quite desirable to me.

Having just checked the MoT history on this one, strange as you like....

First of all well done on an epic build I've enjoyed every page of it, Thanks for sharing .

I'm sure you've considered fitting LPG, What are the main reasons you decided not to go with it ?

From what I can see
- Added weight
- Possible difficulty finding filling stations when on the road
- slight loss of power

+ Increased range
+ Lower running cost

Aren't LPG systems the death knell in the medium/long term for an engine...?

They also decrease range, not increase.

I didn't bother reading past the second line of what I'd quoted... Lol.
I think most people who know a thing or two about engines would be pretty against fitting LPG.

That's why I asked.

Regarding range, the petrol tank isn't getting any smaller and your adding a new fuel source hence the longer range

Yes, but the OP's car already has a secondary fuel tank. I imagine an LPG system would warrant the removal of this.
