sprayed the 200 on 18th. the first run, the clutch slipped in every gear, the afr was 12.25 on average, 78n 41f, timing was 10 deg. retarded from n/a timing values. i used motor sport vp109 and denso it 27, the gap set at .035. on the sencond run, the ls7 clutch gripped but the eng. went rich. so i backed off. i drove 60mi to home and the eng. still purrs smooth like a cat, for now anyways. the next day, i made a thorough visual inspection of all the fittings and also looked at the noids for any debris, all looked normal. ckd. my bottle wt. and it read 31.1lbs, good enough for the show. i arrived at the track on fumes, the fuel trip display showed i had zero mi. left to go and continued to idle for an additional 20 mins. or so and never ran out, i filled the tank with 5gals of ms 109, still on the it27s at .035. i made a total of 3 passes, the first one was n/a, ran 12.533et, 111.08mph, the sixty could have been better 4krpm launch and the clutch held well. 1.834, afr was 13.08 on average. the next pass was on the pills, 78n/41f. 1st gear was the afr was 11 avg., 2nd 11.3, both lasted very short time, 3rd started out at 11.3 and progressively went richer to 10.97, not a terrible drop! 4th was similar 11.53 to 10.67,
the plugs looked good, the timing mark was near the corner of the strap, the pass came in at 11.803et, 125.73mph with a 1.803 60'. very disappointing for sure, considering i went 11.454 and 123mph on the 100 pills. the second pass afr curve was very similar, 1st and 2nd were very flat 11.7, 3rd went lean to rich 11.7 to 11.3, and 4th started at 12.38 and took a huge dip at the end 10.4. i did leaned out the pe by .5 for the pass. fuel and oil pressures were stable and normal, ect rise was only 5deg from beggining to end. i wish there was some way to monitor fuel flow to get a better picture of what's going on. anyway, the eng. still running smooth, next time, i'm going back to the 100 and i'm gonna spray it all at once at 4000rpm just to see if the eng. still healthy, and of course i'll use sunnoco 93. and after that the 200 again. i hope this info helps someone else.
