Major Track Faults of the 370

Pharmacist

too many smarta$$es here

Lay off the OP, he's not an idiot. I too get the exact same problem with the clutch. It happened to me 3 times when on mosport ddt during lapping days. Near the end of a 15 or 20 min session, my clutch gets stuck to the bottom and i have to lift it up with my foot. I then pull over into the pits and within a few seconds the clutch is fine, albeit a bit soft feeling. And if you didn't know, mosport ddt is a short, tight twisty low speed track done almost totally in 2nd gear except for the one single straight where you upshift to 3rd for a few seconds before downshifting into 2nd again for the turn. So the clutch can't be working that hard. And yes I had the stock fluid.

And a few days ago I was lapping at shannonville. The clutch didn't get stuck but after the same 20 min session the clutch would get progressively softer, and i got the occasional gear grinding when shifting. My guess is that it seems the clutch fluid boils a bit due to excess heat after about 15 or 20 min of hard lapping. I'll upgrade the clutch fluid over the winter and next year see if the problem replicates itself.

I experienced fuel starvation on shannonville that same day near the end of my 3rd 20 min session. I was running low on gas, about 4 dots (25% of the tank). Then on turn 3 which is a sharp right, the car just died down and i lost all drive to the wheels. the engine was idling at barely 1000 rpm. I was flooring the throttle and the engine wasnt responding. I shuffled through the gears 1 to 4 trying to get the car moving and it didn't. I was able to get it to creep very very slowly in 1st gear. It was pretty scary since i was stationary in the middle of the racing line, and a couple of cars whizzed by my side at 70 km/h or so. Finally I crept enough to get it to the grass and left it idling in neutral for a few seconds. by that time the fuel level was down to 2 dots. After a few seconds i tried to rev it and it responded, so i took off again to finish my lap. On the same lap at turn 10 which is a right hand hairpin before a long straight, right after the turn and getting ready to floor it for the very long back straight, the car died again for a few seconds before responding again. By that time fuel was down to 1 dot. I was able to finish my lap with no problems but pulled into the pits at the end. After leaving the car idling for a few minutes the fuel level crept back up to 4 dots again I left the track soon after and went back home.

In addition I did experience ice mode regularly after hard braking from long straights, especially since both mosport ddt and shannonville are very bumpy tracks. But that's no problem. As soon as i feel the abs pulsate the brake pedal i lift and then reapply the brakes and that seems to defeat ice mode.
