I went back to the track yesterday after I was disapointed 2 weeks ago with my last outing at the track. Where I ran a 13.43@101 with a 1.81 60ft. Went to a different track this time around and ran a best of 13.16@102 with a 1.78 60ft and a 8.34 1/8 mile. Both outings were in 90 degree weather. Mods are Edge 3200 stall, LT's/ORY, Hooker catback, tune, and MT et streets. Still not completely happy with those times granted it was 90 degrees out and my car weighs almost 3700 lbs. I feel the converter is inefficient up top past the 1/8 mile the times start to slow down and my mph. Also the day I installed the converter my car has had a problem idling as soon as it starts to warm up. I tried changing both o2 sensors and raising the idle but it still wants to stall? Anybody have an idea what could be the problem?

 

thats not that bad compared to what im seeing what people run with similar mods

 

What tracks did you run at? The e.t. looks pretty good, but the mph is definitely down.
