Inspired to try some racing of your own but don't have the funds to take a race car around a road course? Check out an indoor go-kart track. These aren't the slow amusement park machines that can barely get out of their own way! Electric or gas-powered, even indoors real go-karts can fly around a course and can be a great, cheap way to experience the thrills of racing. Bring the whole family!

>>More images of the Radical SR9.  Not a bad looker and it can be yours for $323,000 (sans engine).  These images come courtesy the Radical website
The SR9 has some rather exquisite detailing.
Looking inside the front wheel well, the airflow from the wheel well is free to flow in with the airflow heading towards the radiators.
The louvers in the valence between the fender and monocoque are interesting.

>>Martin short sends an image intense but oh so brief update on the Radical's progress.  These images were taken as of yesterday morning and show the car's progress.  Things are coming along quite well and Martin likens the SR9 as a combination of Darth Vader and the Alien.
The rear bodywork is quite swoopy.
Judd 3.4 liter V8 mated to the Ricardo gearbox.
Of course this is merely a teaser image, the rest of the car will remain under wraps for now...

>>David Legangneux sends this tidbit out of the Ouest-France newspaper on Henri Pescarolos' 2006 plans:

The prototypes that Pescarolo Sport will enter this year at Le Mans and in LMS will look the same, but a lot of small details, a reworked engine and a new gearbox will improve them.  A brand new carbon tub is in the Pescarolo Sport workshop. It will replace the one damaged by Soheil Ayari last year and now given to the local Museum.  Yves Courage, "The past month, we have tested a lot of small things, on the aerodynamics, but also to speed the repairs.  All the rear axle, behind the gearbox, will be able to be changed in a few seconds.  Today, all these evolutions are nearly validated.  The news parts will be made in Italy."  Pescarolo will use the S2 version of the Judd GV5.  "We have saved 20 kg that eventually won't help a lot, because the ACO has changed its regulations.  All that because of air conditioning in GTs, but mandatory a year later.  I will spend more than 70000 E for nearly nothing as I will put 45 kg of lest on my cars.  It's not something defensible and explainable.  It seems the regulations are favourable to them. And their engine could have a lot of bhp.  Some are talking of 720 bhp."   Pescarolo Sport will also use a new X-Trac gearbox. "The narrower gearbox will help us to use for the best the aerodynamic definition of our diffuser."  The new version of the Pescarolo C60 will do a shakedown at the beginning of March, then will do the LMS test days at Castellet on March 25 & 26.

Yves comments regarding the ACO regulations mirror those I've privately received by various teams.  The ACO seems to have missed the fact that many privateers have committed a lot of money to making even the 900 kg weight limit.  Now the investment is null and void with the increase to 925 kgs.  His comments regarding the changeability of the rear end are interesting and warrant further inquiry.  The regulations now disallow quick change rear ends (and have since last year), but that detail certainly could have many uses during practice and the lead up to the race.

>>Racecar Engineering's Sam Collins passes on news of groupBio's progress.  Ian Dawson has indicated the design work has been completed and the chassis (B2K/10) is off for painting.  Lola has overseen ("observed") the hybridization of the B2K/10.  The car will then be sent to Le Mans for inspection by the ACO and, assuming all is well, off to Sebring thereafter.  Here is an image of the car as it was in December (partially hybridized).  Pictures of the completed B2K/10 hybrid will follow next week.

>>A big day for Mick Hyde and the boys of Radical as the SR9 LMP2 monocoque passes its FIA crash test.  The crash certification is a multi part test that includes a frontal impact, a front push test, a roll over structure push test, and a side push test, though not in that order!  The culmination is the frontal impact test whereby the entire kit is loaded up with 925 kgs of weight (to simulate a 85 kg driver [dummy sit-in] and a full fuel load) and rammed into an rather solid object (steel rig) at 35 mph.  In order to pass certain deceleration parameters cannot be exceeded and the impact deformation must be contained (in regards to the frontal impact test).  The SR9 came away looking quite good with peak declarations not exceeding 44 gs for the driver (maximum allowable is 60) and 20 gs for the chassis (maximum allowable is 25).  The project is moving forward rapidly and the first cars are set to be delivered to Rollcentre Racing in March.
The SR9 has the requisite front impact structure that mounts to the front end of the monocoque.  In the image above the crash structure has done its job and completely vaporized! 

Testing was carried out at Cranfield University.

>>Creation's Ian Bickerton sends along a rendering of the hybrid Creation CA06-H.  Ian adds, "This puppy should hit the track in 3 weeks.  A bit late but world carbon shortages are such that we got caught out a little."
