We shipped the car to the Z cars workshop and pulled the TVR engine and box out complete with all the dry sump systems etc
This revealed a large wide engine bay sufficient for our needs,I spoke to my old friend jack frost at Holeshot racing and he supplied two Hyabusa turbo engines which were then fitted back to back in the engine bay.
Special aluminium mounting brackets were made to mate the two engines together and allow everything to be rubber mounted to cut down on noise and vibration (with all that power on tap on full boost we didn’t want this thing to deafen the passengers !!!!!!!! )
This meant that the left hand engine now drives the rear wheels via a differential at the back of the car and the right hand engine drives the front wheels via a propshaft to a differential at the front of the car.
The diffs used were specially made with limited slip and a high ratio to achieve 200 mph topspeed,new rear covers were machined out of solid billet aluminium to allow fitment in the very tight frontal area of the car
we also had to relocate the shock absorbers and springs to allow the driveshafts to get from the differential to the heavily modified front upright,
this setup has been used to very good effect in our four wheel drive Tiger Z 100 WR sports car previously. The Tiger had a system designed and built by us in conjunction with Richard Bulmer from Motec , this system controlled the power available at each wheel to eliminate wheelspin and understeer ,it worked very well and took the world record for a road going car from 0 to 60 mph in 2.8 seconds
We again fitted a Motec A D L dashboard and systems control computer and various sensors to the car.With all that power available on full boost this is the key to a successful conclusion to the project
We weighed the standard copper and steel radiater and were horrified to discover that it weighed 13 kilos without fans and any water inside it so we made up a twin core dual flow aluminium item of our own which weighs 5 kilos and is better looking into the bargain. Even with the fans on its lighter than the one we took off
Having now constructed most of the car we worked on the brakes, David sent us a pair of massive brembo four pot callipers and discs that are from a lambourghini he has and we managed to fit them to good effect the discs measure
Ok how is this little lot going to go,well I think it will go as Rolls Royce used to say “adequately”
