Update for those who have followed Shawn Johnson's carbed mod motor. Shawn's trip to the chassis dyno last night netted 300+ rwhp and rwtq. This is a bone stock 1999 4V with 20k plus mileage.
This hp/tq was generated using a high stall converter and C4 trans.
Shawn ran 11.3s first time out and should run high 10's this weekend at WFC5.
