Default CLR intro

I've been meaning to join this forum for years as so many from UK Porsche circles reference info from here.
My first post here so a little intro into my 996 I've been building for the last 2 years or so. Approaching the later stages of development now so it will soon be laying down over 300BHP/Ton with a dry weight of 1085kg. Luckily a recent article was written by 911&PW so this will save me typing. There isn't a great deal of detail in the write up but enough to get the gist of the project or a few more pictures can be found here (Photobucket recently went t1ts up so this is currently the only place where I have a few other pics).
Enjoy

Nice job! Can't wait to see it all painted/finished off

Hi CLR, can you comment on how the steering is without assistance? is it just heavier or is there a real benefit to feedback and driving enjoyment?

Car looks cool!

How expensive is it to make Carbon body panels?

It would be amazing to make a carbon 996 similar to what Singer does with the aircooled bodies.

Many thanks for your thoughts guys
In answer to some of the questions:

-The manual steering system highlights one of the fundamental principles of this project; it is the only way how I see getting the optimum drivers 911 is possible. On a stock 996 it would be a terrible idea due to the weight and other factors. In combination with the various changes I've made to the steering geometry/steering load reduction, it really adds to the occasion. The car is work in progress though and I'm still looking for a solution to overcome an element of the torsional loads in the front ARB. Whether this further fine-tuning is truly needed or not is subjective but it is something I have in the back of my mind.

-Singer for me forms a massive part of the inspiration for taking on a project of this nature. I have had all my carbon panels custom made to my spec. This is the approach Singer have also taken. By going down this route, you can iron out any issues, the trouble is though it is very expensive. So far the list of custom Carbon parts are:
-Bonnet
-Front wings
-Roof
-Doors
-Door cards
-Mirrors (made from original RUF mirrors)
-Ducktail
-Exhaust tips

Still much to do and the approval process to negotiate but so glad to get it this far

Im about to buy the Ohlins RT coilovers.
I assume they are great.

CLR really enjoying reading on the progress you have made. I like the direction you have gone. you have gone further than RPM have with their CSR. Question, how noisy is it with the carbon panels, does it rattle more? Notice any difference with the flex of the chassis especially with the roof panel. Didn't see but did you install a LSD? Very interested to see where you take this, big congrats on where you have got this too. Any chance of putting it to a tame race driver to do a back to back comparison to a 996 gt3.

Many thanks Sammaw
NVH was an important aspect to contain with this car as primarily it is a road car. I went to extreme lengths to get the balance right (shaving underside of carpet and selected sound deadening removal all in a very progressive manner). With a lightweight flywheel, trick diff, solid mounts and suspension components, polycarbonate window, there is an element of added noise but for me, it is a fair compromise, erring more on the side of adding drama/theatre rather than unpleasant noise, especially so with the Inconel625 exhaust.
Chassis flex: not a bit of it; it is so much lighter now that the chassis is working far less than it use to. I have a few pictures here where you can see how structurally rigid the car is minus the roof. I dropped 23.6kg in taking the roof out, so again this high CofG reduction reduces much of the stresses that were previously there.
As mentioned above yes I fitted a custom LSD. Still in the prototype phase at present and it is currently being redesigned but it should be fitted again next week. It has dual ramp angles (40/60) and a fairly light pre-load of 25lbft once run-in.
I like your idea of a GT3 back to back. I have a serious motoring journalist lined up to test the car in the near future. I'll post a link to the video once it's released. I'll also try and line up a 996GT3 which would make for a very interesting comparison; thanks for the idea


MoeMonney, you will not in anyway shape or form be disappointed with the Ohlins. They are a lovely piece of kit
