RE: best glow plug for TT pro 40
I used those 9X6's and found my exit speeds were terrible and the rpm would signifcally drop off.
I experimented with a 9X6 and cut it down a bit, and that did help. Most of races are at a lower altitude. We race at half the altitude at one venue.
I will try the 9X6 now that I have a radar gun and compare the speeds. Maybe the drop in the turns arent a big deal if I get a lot more straight speed. We run a 600' 2 pole course.
