Any updates on these engines
We got the engine back together and went to a race on Sunday.
We only got one time trial and then one race pass so we still haven't done any real tuning, but the car ran well.
It ran 5.85 @ 117.79 on this 1/8th mile track.
Earlier in the year we ran 9.38 in the 1/4 mile and the 1/8th mile times for that run were 5.97 @116.58
This run was .12 and 1.21 mph quicker to the 1/8th mile mark and I think it's safe to say we'd pick up .01 on the second half of the track since we're moving quicker at the 1/8th mile mark.
So, I'm guessing we would be running about 9.25 in the 1/4 mile.
The biggest difference is in the 60' time. It was a sluggish 1.40 on the 9.38 run.
The 60' time was 1.29 this weekend. I'm happy with that.
The difference was that we adjusted the instant center on the four link to hit the tires harder off the line.
We had started out with a very low and far ahead instant center setting at the beginning of the year. I think that's the smoothest and safest setting to start out with. (less chance of doing anything weird like darting into the other lane)
The next time out we moved the instant center up and back a little and the 60' time improved to 1.35
This time we went even farther up and back and did a 1.29 so I think we're very close on our setting now.
I think this will be our last time out for this year.
I'm anxious to get out there first thing next spring and do some tuning. We've got a bunch of things we want to try. I'm 100% sure we'll pick up another tenth or two before were done.
