I dropped at least 50lbs off the bike switching frames, drag bar, battery, front end.. and shaving the tires. I really think it was more like 70lbs. I have no idea what the asr a-arms weighed on my orange frame or the spindles and rims. I just weighed tne new stuff and some stock stuff I had sitting around. I assumed it would drop 2 tenths. BUt, I also was hoping with the changes to my tires we could hit it with a bit more nitrous and sooner using my controller. turned out we had to run even less nitrous, as in none at all until past the 60ft light, ( I was waiting until I hit the next sprinkler) and even then I had it down to only 10% ( 5hp) and ramping up over a second and half. ..Rich, when you came down and picked up the Prairie, do you have the time slip? seems the 60 was in the lower range. I remember it cutting an awesome 60 but the ET and mph weren't that great........kinda what I expected.Nice pics.
I have 2 questions.
1) How fast did Z-manns 730 Prairie run?
2) Who was the little boy standing by Gauge's brute force? lol (sorry, couldn't resist a short joke!)
Happy trails...![]()
Yeah, it didn't do worth a crap. I didn't put the bar on it, and best 60ft I cut was a 1.99 I think. Was trapping 66-67 mph... but never left on the bottle either.
I have a bunch of slips that I meant to give you from when you came down
Nothing changed from then.....through the race event, exactly the same, when you came down we mounted the sensors in the new housings and got everything aligned then did some testing. and that's the way it stayed.
I'm looking at some of your slips from them, the only difference with your chaindrive is the new lighter front end
most of the 60's were in the 1.5 range, the best being a 1.489, the worse being 1.698 (nitrous), best ET was [email protected],60'@1.489.....that was with a bar height change
every nitrous run Scott tried was slower
nitrous.....60'@1.698, ET [email protected]
I really think and would expect your times to be better after lightening the frame and the new frontend. If nothing else, it was very evident that weight will slow you down. The only exception is running 4 wheel drive, the added traction (not the weight) helps alot, but as we saw with the Prairie, great 60' but the ET and MPH were pretty bad BUT that motor has been around the block and that bike was set up and meant for nitrous
just a few more thoughts![]()
I never implied that the track was set up wrong.. it's not even a question, in my mind that the track is right. you didn't spend all that money to not be.
but when I look at my timeslips, I know different track.. a 4.2 @ 71 MPH, we had a 60' time of 1.62.
and you know, I would call bs on this becuase your 60ft time isn't good enough to only trap 71 and still run a 4.2.... maybe a 4.2999999.... maybe ....
My buddies that run consisten 4.2s all motor trap 74 or so and cut 1.5 60 ft times... Now I do think our belt / autos will trap a bit lower mph than the shifter bikes...
ON my slips, I cut better 60 ft times than yours, trapped more mph... and still ran only a 4.29 on motor... HMMM:lol: But I guess Tom's track is a fast one... LOLOLOLOLOOLOL
I just double checked, and on my 1.4 60ft passes all motor , it was 70. something mph... Seems about right to me?
well, I am not really sure what that has to do with anything. The sensors don't do anything with an average speed. All they do is determine how fast your going based on the time it takes you to trip both sensors.... If the system is set up to read 10ft, or 66ft.. really shouldn't make any difference at all. But, who knows. Ever track is different.I never implied that the track was set up wrong.. it's not even a question, in my mind that the track is right. you didn't spend all that money to not be.

Tom the track looks great.. right on the money as expected.
Z-man, I coming back to this post after seeing Tom's pic's, to clear up why maybe the difference in ET speed and running the same ET times.
The tracks that we run on here in the North, the speed traps are the last 66' of the track and seeing Tom's pictures, his is the last 10' of the track, so it makes sense that your average speed for the last 10' would be more than mine would be for the last 66'. Mistery solved.
Why not just do tilled dirt? It would be easy to do and hooks as hard or harder than sand...no?
