Took my car to the 1/4 mile yesterday for the first time and ran mid 14's/15's. The track is really sticky it takes a bit of practice to get used to. Should be running mid 13's once I get my launch perfected. End of the day, started up the car and heard this weird ticking noise. Not the fuel pulse dampener, something else coming from crank area. After it warmed up, sound went away. Drove 2 hours home boosting no problem then light came on. I've learned that the knock sensor can go sometimes and I don't hear anything out of the ordinary. Anybody care to put in they're 2 cents? Picked up the $30 knock sensor already just curious if anyone else had this issue after dragging it.
