No dyno on the 04 Redline. I do have track slips ET 13.7?? 1/4 mile (89mph). Outran 400+HP 2012 Camaro in top speed contest just after conversion 3 years ago. Don't know all the mods, but the car is well known to San Antonio Redliners and Cobalt freaks. The car was bought new by my son. Unfortunately he passed away suddenly about 2 years ago and I bought the car from the estate for $4500 to keep for my 15 year old grandson. He has decided it is too much car for a 17 year old; that's why it's for sale. I have been driving it regularly as a weekender.
