951 RS bits now being manufactured ;-)

[951rs]

Yes, you are right stating that we did sell the GTS headlight kit from von Oldenburg earlier, I picked up two of them, one was originally destined to be shipped to Patrick (333pg333, btw, you will get the first set of ours, thanks for being patient!) but the quality of the buckets was very poor and the covers were well made regarding the craftmanship but not properly reflecting the shape of the OEM metal headlight covers (they are straight, no curved, convex shape), additionally the installation works with 6 brackets per side which is quite over-engineered and far too complicated and on top of that the covers are fitted to the buckets using screws from the top which is not aesthethically beautiful and not durable under UK weather conditions...and also the price of 680 euros is too high considering the fact that the product has at lot of potential for optimization.

so, as mentioned above, we decided to develop our very own GTS headlight kit which I can already state now will become the quality benchmark on the market. The covers pictured are for the new kit. It will be a complete kit including every tiny little bit to make it a bolt-in kit (housings, covers, brackets, Hella light units, screws, etc.).

Final pricing is not decided yet but it certainly will be a lot below the above number. I will post pics of the first unit fitted here and I'm sure Patrick will provide you with testimonial later...

shaunp, as the old Romans said: de gustibus est disputandum...in other words, I don't mind you calling our products "stick on mods or nasty" but what concerns cheap quality your definitely at the wrong adress. We're always happy to accept positive criticism (and include it in the evolution of our products) and therefore are very open for your suggestions for Heat Extraction Vents which suit the 951's shape better, fit more precisely and are more functional...

Cheers

Hi all

Quick update on the development of our new GTS headlight kit...

Here you go, the new buckets and the "authentic" Hella headlight units. We have designed these so that they are fully adjustable and compatible for both RHD and LHD application. As you can see, also the quality of the buckets / housings will be very good. Our last step in the development of these new GTS headlights are the brackets for installing the buckets properly in the car, that's what we will finish in the next 10 days and then we can ship out the first kits (we already have lots of orders but the earlier you get on the list, the sooner you get served ;D )

Cheers

Looks nice Beni. Is there a twin round lamp version in the pipeline?

Looks nice Beni. Is there a twin round lamp version in the pipeline?

[] my thoughts exactly

 

[Peter Empson]

Personaly I think you should stop messing around with the turbo shapred ones and concentrate on the design for the early cars [] []

Looking great though, can't wait to see them fitted.

 

[333pg333]

Looks fantastic in my book!

 

[John Sims]

Looks good to me.

My only reservation is would it fit with my air filter?

Even as I look at the above picture I think how nice it would be to get ride of the headlamp motor and brackets. It would give me a much better location for my catch tank for a start.

I do agree with Tony though. While twin round projector type headlamps may not be "authentic" they must provide better light than a rectangular unit. Rectangular units are reknown for being poor in their light distribution - probably not even as good as the original lamps in new condition.

hi benni

about the vents would it be possible to make a vents that sits into the bonnet .

i had cooling problems with a v6 st24 i modded and i used genuine cosworth vent but these where fittted in such a way that they be came part of the bonnet .
the shape was cut out and then the lips where rolled and the vents fitted inside the hole this gave a much flusher and neater fit .

i take it ur vents theres a hole cut out and the vent sits into the hole giving a lip on the bonnet .

i feel if u are going to put mods like vents on they must look like they are factory fit

i will try dig out a piccy for u

ps the head lights look shit hot [][] wheres my cheque book

I'm with you John, I think the twin round projector type lights would look the dogs danglies. Also if you had a small lens'd indicator in there as well you could ditch the stock inticators for a brake cooling duct and retain the standard fog/driving lamps. I'd use the space to mount the intercooler horizontally and have it vent out of louvres in the bonnet.

Hi all

Update...first pictures of the covers meeting the housings (please note that these are prototype covers and that they do not have the refined carefully sanded edges yet):

Our first version will be the recantgular authentic GTS headlight units. These will offer sufficient light performance if using 100W bulbs which I guess you guys in the UK won't have any problems with. We will add a more modern version later this year but probably not before autumn.

John, can you please take a picture of your engine bay from an exactly vertical perspective as well as check if you can push the air filter a bit more backwards to the cooling reservoir? It looks to me as if you could get some more space if optimizing the position of it. Need more detailed pictures though to provide you an estimate if the headlight unit fit in there.

shaunp, I see your point, We intentionally did not want to create heat extraction vents which are mounted from below for the following reasons:
There is only minimum clearance under the vents, if you have installed a strut brace (as 99.99% of the owners installing these vents) and you still want to have some tolerance built in, you can't install any efficient vents from below as this would mean mounting them 5mm's lower then colliding with other items under the bonnet.
In addition, we want to offer these vents mainly for the various FRP bonnets there are on the market...they all have different material thicknesses and we don't see any viable design that is mounted from below which can properly be adapted to different strength of material and still is aerodynamically efficient.
Please note that this is a performance upgrade for the performance minded clientele. It still looks nice IMHO and fits well but is not a part for the concourse enthusiast.

See this picture - both the strut brace and the coolant reservoir filler cap are QUITE close:

Have a good weekend

Cheers

benni with regards to the head lights are u taking deposits for them

 

[George Elliott]

Beni,
good to see some nicely engineered mods for the 951. There is no doubt someone has put hours of work into all this.

I am not a fan of 99% of Bonnet vents on the market. (I do really admire the original Porsche 968 turbo bonnet Vents and the 924 Turbo badge panel vents, and the 996GT2 vent, and all the 917 vents and...basically Porsche were excellent at this.from way back in the peoples car & 356 days).

Your vents seem engineered to draw air into the engine bay (based on the angle of the slats?). I would expect that the airflow would have been based around air entering at the front, flowing thru the Air Con / Engine Rad / Oil & Intercooler and flowing out at the rear of the bonnet taking general underbonnet heat with it.

Any plans for an OE style vent / badge panel, engineered to cool the underbonnet and preserve the wiring and rubber pipes from being age hardened as they are in a standard turbo?

Is your MAF related to a Sci Vision may I ask?

Thanks

George

shaunp: No, we aren't taking deposits but please drop me a pm or e-mail so we can put you on the list, first come - first serve. Off course, this also applicable for everybody else.

George: I guess the picture I posted is a bit misleading. Please have a look at this one:

The vents are designed to allow the air to escape (not to enter!) via the upper side of the bonnet. This flow is supported by the air which flows over the cars body and the vents and therewith produces a "vacuum effect" which effectively sucks the hot air out of the engine bay. A basic rule in aerodynamics states that the outlet area has to be 2X the inlet area, that's why we have designed these outlets rather large, the 951 features lots of inlets at the front but no outlets at all.
I guess I don't need to mention the high engine bay temperatures encountered on 951s...to me it's obvious that Porsche had not done their homework.

Also I may not fully agree with your statement about Porsche designing nice air in- and outlets:

924 turbo / CGT: the front inlets are quite functional but the top mounted Naca bonnet inlet isn't engineered very well as it only cools the header and produces lift at high speed. I'd rather have a large inlet area with different channels at the front and then some outlets at the back.

968 turbo: Nice! solution with the intercooler, but this flow-through setup only cools the IC and not the engine bay. I'm also not a big fan of the two NACA inlets in the bonnet, I'd prefer larger inlets at the cars front which then are split and channelled specifically to Radiator, Intake, Turbocharger cooling and Header cooling.

Cheers

Beni

I will do another prototpye of my earlier badge panel this summer, it will look like this:

Regarding hoses and pipings that age we will have a silcion hose engine bay kit available soon...

And yes, our MAF uses Scivision technology. Do you already know / use this over in the UK?

 

[George Elliott]

Beni,
thanks for answering all the questions, I had mis-read the photo - your slats are drawing out not in, my mistake.
Sounds like Porsche do not have your approval for vent function..........perhaps designed by the marketing dept.
Will too much airflow allow moisture, mist/fog/rain to dampen the underbonnet area, the hot conditions do keep everything nice and dry. Could the vents open and close with a stat?? or the I/C be ducted separately at the lead edge of the bonnet?
Your single slot I/C vent looks OK, the proportions are in keeping with the cars other vents, - have you a 4 vent design like the 924T available? (I have a set of the plastic grilles for it!)
I have a SciVision on my car. Its smoother than the AFM, but there is no real performance gain at my low level of tuning. Promax supply them in England.
keep up the good work

[333pg333]

George, those vents are rare as hens teeth (not available from Porsche anymore.) if you've got original 924 turbo ones? Unfortunately the 931 panel doesn't fit our cars, however if you have those vents you can have someone do some mods to a spare 944turbo nose panel to achieve this look / effect. I am in fact having this done at the moment and I will be having some hood venting done to create the flow through to help i/c and radiator.

 

[Peter Empson]

Patrick, do you have any details about your hood vents that you're able to disclose? I'm starting to wonder if I should be looking into this more seriously before it's painted.

 

[xenon]

Regarding the headlights, I'm guessing OK for a track car but could be iffy on the road for the MOT unless they're 'E' marked (?)

I'm afraid its as snug as a snug thing. If the fixed lamp fits within the area of the existing closed headlamp it will fit, otherwise it won't.

With regard to 100w lamps in the UK. They are illegal. If you have a bad smash you could find your insurers won't pay up. Also, unless you have an IceShark conversion, they will probably melt your loom as well.

Peter you must have the bonnet vents. I believe the area of hole is greater than the mass of the vent material and therefore you car will be lighter. []

Peter you must have the bonnet vents.

I thought the rule of thumb was that exit vents need to be twice the size of input vents.

Seeing the vents on Peters new bumper leads me to believe he should just do away with the bonnet all together
