Well i finally had my first day out with the B5 in my truggy. I ran 8 tanks through it on the box at idle last week and was ready to hit the dirt. The first tank i did not tuch the needles from were it was during break-in wich i thought was a little on the fat side since the temps at idle were around 170-200. Only a couple of laps in the temps got to around 235-240 but still smokeing. The track was dry and slick and temp was 95 and humid so i decided to richen it up a little to keep temps from getting to high. after 2 more tanks the motor was SCREAMING FAST and temping at 212 after the 5 min qualifiers and still had 1/2 a tank of fuel left. needless to say i took TQ and the win. Motor ran great all day and never gave me any problems. Also still on the same glow plug that i used for breakin 97t. Thanks again Ron for an outstanding product as usual.
