Another lucky Sphere Competition owner here.
Dear all, I am pleased to say that today I tested the Sphere Comp. LRP Star 4 Vector motor, in a damp track just to see how it went.
Well, all I have to say is WOW!!!
The car accelerated as hell! Great top speed and very good at the infield. I would say it acts just like the 7x2 I ran the past week, but with more run time!
I think that this time they did it. I am very happy with the motor and the speed control performance. I only wish it could stop raining so I can test the car laptime-wise and see how it really goes. To the naked-eye it looks insane.
Anyway I want to ask Reto something.
Reto, the car seemed undergeared to me and Antony from LRP Greece with the final ratio of 8.0, and the ADPC at 5 and 6. So we went down to almost 7.50 and ADPC 4 and came out with a great result. Can you please tell me, what are the acceptable temperatures for the motor and speedo? Is there anyway to understand whether the motor is undergeared or overgeared by means of the temperature of the two components? When I tried the extreme 7.33 the motor came out at 70C and the speedo at 60C using just the heatsink not the fan. Track temperature 12C. Is this ok? The track is huge and has an 60m straight and a sweeping right turn at the end just like in EC 2004 in Austria (Antony said you would understand
P.S. Good job Reto, I am surprised, oh and by the way.... The new IB 4200 Vtecs showed some great numbers on the Turbo35 GFX!!!!
