I just got the killshot 21.5 Torque version for my 21.5 class here locally. Can anyone give target temps and maybe a FDR to start with? I ran it for the first time yesterday at 3.41 and 60* timing and came off around 125* after a full heat. Found I was still lacking a little top end compared to others in the field.

They do have a RPM version I believe as when I ordered it they asked me which one I wanted. I have dropped the FDR to 3.25 but have not had a chance to test it yet. I also am not running a fan on the motor as of right now but do have one to put on. Just waiting to test the current FDR first. So the no no temp range is 170* right? Just not wanting to smoke it.

They briefly mentioned something about it yesterday. But I was late so I was rushing to get my cars ready for the heats so I missed it. I think they were talking about the 2 day race if I remember. I think that is what you are referring to? 2 qual heats saturday and 1 more qual and mains on sunday. I will look more into it tomorrow and can let you know.

I tried searching but can't find much info on the D3.5 17.5 in 12th scale.
I have the motor with stock rotor and I like to start my tires around 43.5 mm. I ran a 53t pinion with 74t spur this past weekend and it seems like I lacked top end compared to everyone else. I move the timing up to 20 degrees and still seemed slower. I saw a few people in the 12th scale forum say they are using max timing on their motors, but i"m not sure exactly what that means. the temps were around 156 degrees.
Anybody care to help me sort out this "not enough top end" problem plus I don't want to burn the motor trying to figure it out myself.
thanks.

From what I had heard several guys at the track say is that the D3.5 develops a boost in performance when run right at the ragged edge of its critical temp range. So say 165-170* range it develops a noticeable amount of extra power. But even they say it can be tricky to find the sweet spot unless you know the car and where it already needs to be setting wise. They made no mention of endbell timing setting though. Maybe someone else can help provide the missing info?

That's a pretty big rear tire. But I'd say your under geared at least 5 to 7 teeth if not more.

Phil, i run one set of tires per club race. Stay off the boards and dots and there's not much chunking to worry about.

Trinity (Ernie) we are looking for sponsors.
We are having 3 rounds on Saturday 1 round on Sunday followed by the mains. After this race we are hosting another race later in the year we are working with a MFG for that race. We are working on paving our track and building a dynamite layout, That isn't written stone either we have the money now we need the landowner permission.
