R56 Quarter Mile Trouble
I took my car to California Speedway completely stock for the second time with the only difference being an Alta Panel Filter and what a shock. Last time I ran my R56 Auto Trans between 14.95 and 15.1 at 90-93MPH. This time I only ran twice and then shut it down because I ran 15.85 and 15.98 at 83MPHH both times. My 60 foot was the same as last time around 2.25-2.35 but the car just died after 40MPH. I don't feel like the car is bad driving around town but maybe it has been gradually getting slower because of a problem and I have not noticed. The weather was 70 degrees and my friend who raced his mustang both times was within 2 tenths he actually went faster so I know it wasn't the track

Does anyone have any idea or had a similar experience

 

Man, i don't know but the filter wouldn't do that at all. Just make sure it's sealed right.
