Hey everyone - Good news and bad news, 9/28/03. 52 degrees, with 70% humidity, and races were cancelled. But we were able to get 4 time runs in.
Last points season race, and guess who came in 12th for the season, out of 48? Cool, Huh!
Any ways, for the long awaited information:
Same setup as last week, (best time was 11.206 @ 111.634mph)
1st run - K&N filters, with Holtzman red springs and 160 mains. (no nitrous) Was way too rich for this temp and humidity. Plugs were sooty black, and it fell on her face, whenever I went full throttle.
1.715 60 ft. 8.212 @ 76.882mph (The rest stunk)
2nd run - Burped the Nitrous to clean up rich condition. Still not a good run. Fell on it's face after 1/8 mile.
1.727 60 ft. 6.818 @ 103.438mph 1/8 mile 10.825 @ 114.435mph 1/4 mile
3rd run - Took filters off to help lean out without changing jetting (no nitrous) Fell on it's face all the way down cause of jetting.
1.614 60 ft. 7.798 @ 80.058mph 1/8 mile 12.988 @ 90.756mph 1/4 mile
4th run - No filters, and added weight to the HH's (setup was 7/16 middle and tip, with 2 thin and 1 thick washer in middle and tip) Engaged the Nitrous after the 60 ft., and broke the track loose, let off and engaged again, 3/4 way down the track, I let off again, due to bottle pressure drop. Here is the results...........................are you ready?
1.533 60 ft. 6.496 @ 104.260mph 1/8 mile 10.441 @ 118.821mph 1/4
That is .765 better than my best run last week! And this is only 48 horse!
Not bad for a non-full nitrous run. The red springs work real well with the K&N's, just had the wrong jetting. We are done for Kaukauna, but Great Lakes Dragway will be open for another month, and will make 1 or 2 trips there yet. If you would do the math: my best 60ft. was 1.483, and a good full nitrous run without letting off, and a 100 lb. lighter driver? 9's? Definelty 10.0's!
