Dude the +4 I got from you last year is still running awesome. I replaced the front bearing after 5 gallons cause it started to leak. Another 2 gallons now and running like a swiss...er..Italian Stallion. I'm impressed how quick and smooth the +4 runs. There's no crazy WFO hoping to make the jump moments. Just get the car lined up and roll into the throttle, but not too much, don't want to over jump too much. LOL. I've been averaging 10 to 13 minutes depending on track. I want to run a 45-minute main real bad so I can go for 3 pit stops. It will do it no prob.
