Jes asked me to give some info on my 75 track car. I am using it for a raceseries in Denmark called Club Race. Cars are categorized after weight and HP's.

Chassis fully re-welded from front to mid car.
Weight app. 990 kgs.
Dashboard, heater etc. removed.
All original electrical wires removed. New wires installed.
Autogauge tachometer, oil pressure, water temperature, oil temperature meter
Upper and lower front A-arms in steel tube.
Adjustable “knife” front anti-roll bar
Caster ball joints
Shankle anti-roll bar back
4,0 degree negative camber in front
1,2 degree negative camber back
Watt link upside down, ball joint connections
Centre dion axle uniball kit
Avo coilovers in front and back
Short steering rack, no servo
298 mm brake discs in front. 4 pot calibres from Porsche 944 Turbo
Vented and grooved Zagato discs back, calibres modified to fit discs
Homemade roll cage
Lexan windows
Hood lid in fibre glass
Trunk lid standard (lightened)
Front bumper in fibre glass
Back bumper in fibre glass
8x17 wheels w/ Dunlop slicks 235/610/R17
2 x 40 mm wheel spacers in front
2 x 25 mm wheel spacers in back
Small battery mounted right of driver
Sparco seat and belt

Engine:

2,0 T-Spark
AH Motorsport intake manifold
45 mm Throttle Bodies (unknown make)
Megasquirt engine management complete squirt and spark
50 mm custom made exhaust manifold
Close ratio gearbox (Colotti type) (2,57 – 1,94 – 1,55 – 1,22 – 1,00)
At 7000 rpm’s the speed will be as follows (theoretically):

1. gear 76 km/h
2. gear 101 km/h
3. gear 126 km/h
4. gear 160 km/h
5. gear 195 km/h

I drove last season with a standard engine (132 HP) and gearbox. Max. in the series I am participating in are 160 HP for a car with the weight 990 kgs. Above modified engine has not been started up yet, so HP etc. are unknown. Will update when known.

Damn, thats one awesome beast you've got there!..excuse me while i go find my jaw..its somewhere on the floor.

Wow, I like the way you reversed the watts linkage, this lowers the rear roll center but it dosen't look like you changed (lengthen)the arms? By the way how competitive is this car in the series

Front-end grip must be insane

I love the front swaybar. Very clever, Is it your own design? This is the first time I've seen them outside of Formula SAE cars.

Cheers, Scott

So where can I order a set of those bumpers?

The length of the arms are pretty much the same. They are fastened with ball joints. The car is basically competitive, but the lack of horsepower in the previous season (Nearly 30 HP) and the lack of skills from the driver (me that is ;-)) made the car end up on a 8th place out of app. 20 cars of different makes. Pic shows me and number 1 and 2 in the series.

No, it is the previous owners design. Quite a handyman he is.

http://www.spoiler.se/ The homepage are being changed to a new design, so give them a few days. The company is located in Sweden.

Hej Henrik,
Any developments on the car besides the engine since I saw it last?

When is Johanssons going to get there site up and running?

[Zarcon]

You have modified the dedion to lower the rear roll center. This is a change I am curious about. When you changed the rear roll center, did you need to change the front roll center as well?

Don-
You are correct, the watts linkage mount point has been flipped. I believe the point of doing this is that it lowers the roll center of the rear suspension. I am wondering if this modification also requires a modification to the front roll center in order to bring good results.
