The wait is over

[944Turbo]

ORIGINAL: TTM

For what it's worth I noticed a significant reduce in oil contamination in the intake since I fitted an oil catch can. Mine doesn't vent to atmosphere though, is in closed loop with the intake.

Me too actually, and mine also recircs, but I do still get oil in mist on the intake pipes, just takes longer to form - think a catch can is well worth having just because of the metal pipe under the intake. This gets full of carbon and rusty scale and if any comes loose it goes straight into the turbo intake with the standard set up.

I dont actually have any experience of it but I remember one of the criticisms of K&N and similar filters is the oil can destroy hot wire MAFs - the internet wisdom is oil gets on the MAF gets hot and carbonises destroying the MAF and if there is enough oil escaping a filter it doesnt take much. If its true its a shame as otherwise that cold filter set up looks great! And with the MAF there you get air temp after IC as it goes into the engine, which I guess in the standard position there is a carefully calculated 'guess factor' as to how efficient the turbo and IC is.

As an example the Vitesse MAF kit includes a K&N cone filter so I would guess this particular MAF sensor is not much "excessively" prone to failure because of the oil of the cone filter. As far as I have noticed, Bosch MAF sensors are apparently another story.
Others went for a similar set up and didn't seem to have met any issue, though they might consider normal to inspect/clean the intake regularly in order to avoid any issue.
(Eventually I would like to move the MAF there in order to make proper 4" piping in front of the turbo which has a 4" compressor cover)

That's an interesting topic on the oil catch can possibly producing excessive back pressure. Does anyone know the size of the hole you need to the filter to prevent this? I'd like to check mine, I know what happened to a previous car when my sump breather pipe got restricted it resulted in 1 very oily engine bay and many blown oil seals!

Details of the bodyshop who have my car are:

They did a respray on a 'flip flop' colour for me on my Cerbera where no one else locally could. The job they did was fantastic I felt they went beyond the call of duty to insure it looked right where someone had done a fibreglass repair they weren't sure about so they baked the car in the oven without paint and sure enough air bubbles started forming in the repair so they cut it out and did it again without extra charge.

One thing I like about them is once he's set a price there are no hidden extras. He called me in to show me WUF when he said he needed to talk to me about 'what I wanted to do in certain areas' I thought here we go, I didn't need thay kidney anyway, when I got there he just pointed out the things he'd had trouble with, asked my opinion on a few bits like whether I wanted to risk taking out the old windscreen that had been there for a while (I said yes as it was bubbling slightly there) and said 'ok give us a call next friday and she should be in primer'. I like that attitude.

Is this your car Thom?

IIRC enlarging the hole in the air/oil seperator (part of the oil filler plastic) helps

This has already been done on the advice of a Porsche technician well known to this forum, I was also told that the breather system on the 944T can't cope once you get over 350bhp and needs modifying, hence why the hole has been enlarged, I intend to look closer at the breather system in the future when time permits.

Update with pics. The first picture is the worst extent of the rust on the sills (rear passenger side), the metal has all been cut out and replaced as shown on the second photo but I challenge anyone to find where the weld line is even now before any filler has been put on! It is the highest quality of metalwork I've ever seen, to say I'm pleased with them is an understatement.

Unfortunately they're still having a lot of trouble with the fibreglass panels, they described the badge panel as a lot better but its still been a struggle because it didn't fit when lined up on the car. Front of the wings are also not great where they meet the bumper. Both parts are being cut and re moulded over the next few days. Pic below shows the issue.

Got a direct replacement Lindsey racing LR75 turbo which Mark K fortunately had spare. It's chuckle worthy in size so I thought I'd take a pic to illustrate that point with a coin for scale. Its a well proven turbo and has done WUF proud for many years but I wasn't sure about the accuracy of the ballancing work (second pic) so I took it to a company to have them check before it went on the car and they've commented its fairly basic spec. They managed to persuade me to have my own turbo made up locally. So I'm having an identical size and fitment turbo made with more modern components which should be similar but flow slightly better than the Lindsey item. I'll post up photos of that turbo in a few days when its finished.

All sounds good and that metalwork is magnificent.

I just noticed this on your signature: "The 944 turbo - Good things come to those who wait"

Is that a reference to the amount of turbo lag most of us have grown accustomed to? []

 

[DivineE]

[] certainly is. lol. WUF more than most!

 

[MarkK]

Body will be superb can't wait to see some pics of it next stage,looks like you struck gold with the bodyshop!!

 

[944Turbo]

looking really good, bet you cant wait to get it back!

 

[Hilux]

I may be odd (apologies as it not a critique) but with that kind of power why go down the route of F/G panels that dont fit??

Me.........and I have build many cars..............would simply throw out the interior and spare tyre to save some 40 - 50 kilos but would keep it metal all around or add 10bhp to the engine output and no need to use inferior panels.

Mind you thats just me............

 

[Diver944]

Where did you source the FG panels Ben? To my eye they look like they may be the 944 Lux version and not the Turbo/S2 version, wich could explain the complete lack of fitment [&:]

Love the metalwork though - those guys are good

Front wings ordered through pro 9 []

When I was doing the research before buying mine, I was told that the Pro-9 wings (and all the others sold in the UK) are indeed Lux shaped. Nobody sells direct fit S2/Turbo fibreglass wings in this country. That's why I went to the effort of importing from Teilecar in the end.

I imagine it's also why Ben wanted a bodyshop who really knew what they were doing with fibreglass panels, to be able to make the necessary adjustments cleanly!

Interesting observation regarding reducing weight... I installed back the rear seat panel in the turbo (for the MOT, along with rear seat belts) and since noticed weight transfers were more preditcable, and logically I get better traction. It had got so tail-happy with the torque from the new engine that adding weight actually added active security!

Looking forward to seeing pictures of New Wuf []

Looks like it to me. Ironically, the 924 badge panel Wuf had, that I don't like on later 944s, would have fitted the FG wings. [8|]

Didn't realise it was getting such a makeover, really enjoying the diary and the outcome will no doubt be outstanding

Thanks poprock for filling in my response to Paul's question

To be honest weight was a bi-product of the fibreglass wings. The front badge panel for stone chips and the front wings for their dirt traps were in my mind the most desirable panels to replace with fibreglass to avoid future rot, they were cheap to get hold of compared with having new metal fabricated to replace the corroded bottom sections and I thought shedding a bit of weight from the front end could only be a good thing for the handling.

I might get a few extra horses from the new turbo but making the car faster is not a priority. I'm just going to go through the car bit by bit polishing it up again for 2010 so its got a fresh start. At the moment there are a few things like the turbo and clutch which are putting me off a track day or doing a trip to the Nurburg ring. I'd like to feel free to do those things when I want to without worrying.

Haha"”that's exactly my reasons for for changing to fibreglass wings as well. Pretty much word for word what I've been telling people when asked about them!

WUF's looking great so far.

Hi Ben, as you know I have been on holiday but your earlier posting has puzzled me throughought and so I must ask someone to explain to me how the intake temperature ater the intercooler is much lower than the ambient temperature?

Air in the inlet sytem after the turbo is at a higher pressure than it entered the turbo - so quite apart from the heat from the turbo unit - it must enter the intercooler hotter.

The only way I know for the ambient air to cool the charge temerature lower than its own temperature (well it can´t inside the intercooler and temperature gradients accross different materilals mean it must still always be hotter than ambient) would be if the pressure dropped after it left the intercooler at the place the temperature is being measured. But this seems unlikely if it is to enter the engine under positive pressure? especially as the dimaters of the various pipes don´t seem large wnough to affect a temporary pressure drop anywhere. Is it because the venturi effect at one small diameter, just where the temperature is being measured has lowered the pressure as the air flow speeds up?

However to achieve over 100% volumetric efficiency (which from the outpùt it does) the pressure must always be higher in the engine?

I am sure there is a logical explanation and I am just too much in holiday mode to work it out - but it is releative to our discussions about my plans for the intercooler on my next engine so it is niggling me and I would like to have it explained.

Maybe its just sensor calibration?
