??? for you cl65/cl600 twin turbo owners!

4 questions:
1. how can i tell if the coil packs are going bad?
2. the heat exchanger/ ic pump. when i first got into the car and drove it, it was awesome. drove it kinda of hard, let it sit while running for about 15min drove it back to the house and it just didn't feel as strong/fast as when i first took it out. any ideas/ thoughts on this? temp was about 60deg. could this be heat soak or what????
3. had traction off while driving, felt like it still engaged when i got too much wheel spin. is this normal?
4. are these rearends/trannys tough? can they handle the torque with drag radials an ecu upgrade or even stock? thanx, john

1. You will eventually get a fault code for the coil packs and or it will go into a limp home type of mode and will shake pretty violently.

2. Yes, it sounds like heat soak and possibly a bad intercooler pump especially given the outside temp.


3. You can't completely turn off the traction control unless you are in dyno mode.

4. Yes, the tranny is probably the strongest part of the car and are good to 800+ lb-ft of torque. There are tranny mods to take it to around 1000 lb-ft.
