The mirrors are not road legal, mainly because you can barely see anything with, but very light : http://www.aprperfor...id=91&Itemid=74 The paint job has been done by a really good professional of course.

Here are my new pieces beeing worked out. They are made in extra high quality aluminium (extralight and strong) like you can find in Le Mans prototypes like this one :

I do have the solidworks files so I am able to build other ones for those interested. Please let me know asap by email.

The air admission including the silicone hose :



Weight 640gr, 7 bars pressure approved, gain -0.5kg compared to Regelin admission, price is 399 euros. You need a small silicone (http://www.samcospor...ght_coupler.asp) to connect to turbo.

The admission plenum including his silicone hose.

Weight 700gr, 7 bars approved, gain -1kg compared to oem. Price 599 euros.

Oil return durite (from 1 to 2)


Weight 170gr, gain -230gr. Price 319 euros.

I will show you the prototypes when ready. Delivery is planned in September.

Some work done today :

Now in place :

Looking good.

[rapidos]

Thanks.
In order to compensate the extra weight added by the front splitter (3.5kg) I built this master piece three times lighter than the original plastic one to decrease the height of the gravity center :

Looking good. Love the sills now there in place. What's next on the agenda?

[rapidos]

The extra light alloy pieces above (#142) are beeing worked out, release date september, weight saving forseen 1.48kg on the rear, then hardtop, new front bonnet (-3.4kg), then in winter new front clam (-2.5kg), and some really hot stuff...

Gilles, I also use Solidworks (2011). Have you done any rapid prototyping from your CAD models or used stereolithography to produce any items? If so, who have you used & what actual size objects can they produce? Do you have access to a 3D digitiser or large scale 3D scanner? ...You must have the lightest VX Turbo, although several of us NA boys have light car's now.

So, why such heavy wheels ???

[fred666]

i cannot belive your driving, its unreal. the car is an absolute weapon and you sure know how to use it. those kevlar/carbon arches are special too.

[rapidos]

@MAXR: The prototypes are beeing built. I will first test them on track for validation and then it will be no problem to use the program and produce clones. The plenum/intercooler one is already a big one... What you see post 143 is the large scale 3D scanner. The only avantage I could have is the torque compared to your light N/A vxs. I am running 279BHP with stock engine so still some good step forseen for next season... @2-20: Those are the lightest alloy 17'' wheels for the speedster. @fred666: The car is very easy to drive, but I agree; Some say I am a supernature...

Approximate weights are 8,3 Kg (front) and 9 Kg (rear) for the ATS DTC

I thought you were running a stage 3.5 from VX-performance?

And yes, I really like your project 0,8!

That is correct. 309 is the advertised power, 279 is what I have in the real world at the wheels. Already not bad with stock internals used on track

[Tommess]

So, have you been on an indepedent dyno for measuring then?

[rapidos]

Yes, I did several, 3 different places, top power recorded was 279HP and 399Nm of torque.

Alright, and what's the power at the flywheel? As this is the only way to compare it to the power figures that are given.

No idea about the power at the flywheel. The power anounced is always the power at the wheels on the dyno. Having minus 9% between power anounced and real one is still in the normal range for me. That still makes a good and real 3.2kg/bhp ratio.

what wheels you running buddy?
