Monty, today we had a club race and I took 1st in buggy and even beat out last years Vietnam champ and the number 2 guy last year as well. The Fusion ran great! Ran the 2096 and 021 with the buku heavy shoes and a buku cap in my XB9. I was pitting at 10 minutes when everyone else was pitting at 7 and 8 and we had a miss communication and I stayed out for 11 plus! I noticed the high rev and luckily I was near pit road and got in just in time.

Now for the truggy results. Not so good, I got 4th which isn't so bad considering I tried the 9853 pipe for the first time today. I am not sure if it was the clutch or the pipe. I only have one 021 header so I ran the tighter mugen pipe as it is the closest to the 021 I have besides the one on the buggy. My problem was my bottom end, there was NONE. I was struggling the entire race, I would go about 15 feet before the engine would start to come to life. When I ran the hong nor 2080 it seemed okay as I was able to hit the jumps easily, but today there were two jumps that I would have to stay in the throttle all the way up to and around the corners which ended badly moire times than it did good.

Losi 8ight T 2.0 I am running the buggy gears front and rear as I can NEVER get the rear to last more than 15 minutes but still running the truggy center diff. Bonitto engine with the 9853 and the mugen header and the losi 4 shoe clutch. I haven't taken it apart yet as I just got in the door. Do you think it is the clutch or the pipe, or the gearing? I do have a spare center buggy diff, and I guess I can try one more time with the truggy rear and front if I have to. I am thinking of trying the 2058 and the 2080 again and see if that helps, but my clutch was just rebuilt at the last race and looked good. Nothing seemed to be slipping, it just seemed very doggy for the first 15 or so feet, on the box it would balloon like nothing but on the ground it took a while to get her to wind up, but once it did it was evil, the problem was that I couldn't make up the difference and with the big jumps on the track I was stuck going up and down instead of over them which really hurt. Everyone was surprised because last truggy race my Losi was the fastest one and this time I actually was about the slowest.

The Losi rear diff issue is the reason I am looking for a new truggy, every time I have built it I did it like they say. New everything, even spider gear housing and diff housing, aluminum inserts and NEW shims along with bearings and ring and pinion. I build it where it is notchy, then run a tank or so through it and come in and reshim it if it needs it. Then when I go out and try to race I get about 15 minutes before I hear the first pop. My throttle idles down quickly and I rarely land it with my finger on the throttle unless I have a pretty bad entry into a jump. Any help would be great, especially as I don't think I can repeat at the club race today it came down to fuel mileage as I was about 1/4 lap ahead of second, and I had 1 less fuel stop without it I would have been 3rd.
