2003 Cobra 3.0 Pulley and Tune

Recommended Posts

Im gonna try to share some more of the projects that we have been working on a little more. Last week we got to take care of a customers 7k original mile 03 Cobra last week. The car is spotless in and out. It spends most of its time at shows and shows in the stock class. The customer was just looking to get a little more power out of the car but his stipulations were that he wanted to keep the oem pulley cover on the car for the "oem" look. We opted to go with a 3.0 pulley to prevent belt slippage as much as possible since he did not want to run the larger idler that requires removing the pulley cover.

The car put down really good power stock. It is equipped with a K&N cold air kit and a Flowmaster axleback.

We used a metco 3.0 quick change pulley. That way if he wants to change pulleys later he doesnt have to worry about pressing the pulley on and off.

For those looking at afr's they are all displayed in lambda. All AFR data was collected in the drivers collector using our AFM 1000 wideband. If you want to do afr to lambda conversion just do lambda x 14.68.

 

The car felt great on the road and the customer was really happy. In the end that is what puts a smile on my face!:D

Nice gains. Billetflow has a much nicer looking system, but a pulley swap from those cars really wakes them up. It's just a matter of time before your customer catches the mod bug:D.

He was adamant that the cover had to stay on so when we were done back on it went.

 

"but it's a all stock car, hell the belt cover is still on it" :ninja:
