I just got my 2 JS full mod engines before motorama and only put like 1 tank through both of them in my buggy and truggy before leaving for the race. I can't find one bad thing to say about Ed's engines. I am running the 086 in the buggy and the 007 in truggy. Both were very quick off the line and real fast down the straight. I was hoping that running the full mod in truggy that I would have enough bottom end. Let me say this thing has plenty of off the line punch, you won't be disappointed. After running both vehicles for 7mins. I still had just a little under a half a tank left in both of them. I can definitly see 10mins of runtime. Thanks Ed for such a great engine, and Joe for your help and support. By the way Joe, your air filters and filter oil are awesome.
