Hey guys, I went to the track tonight, got an average couple of passes.
I'm not sure if the results match up with the parts installed but it felt good the entire pass. maybe felt a little sluggish in 3rd gear passing thru the traps(auto)
60'.......2.005
330'.....5.672
1/8......8.718
MPH.....80.34
1000....11.369
E.T......13.616
MPH.....100.09
mods, forged rotating assy 8.4:1.. stg.3 sc heads. chevy springs. .550 lift 214/214 cam 114 sep.. ported 94/95 manifolds, no cats, M.E.S. 2.5" exhaust. ported 94 m90 with MP plenum. 75mm TB. lightning maf. lightweight front wheels, nitto drag radials on the rear. shifting at 5000rpm on every shift. racing weight is around 3650lbs. one wheel peel during launch, so I had to launch very softly. footbraking to 1200rpm then progressively going to the floor during launch.
I think my intake temps are screwing things up. once I get to 144* it pulls 4 degrees of timing, 150* it pulls 6 degrees. anything above it pulls 10 degrees. I set the IAC table to start pulling timing above 150, and once it gets to 150 it only pulls 3 degrees. I noticed that my car stops pulling as hard after the 1/8th mile. the whole run the timing was 21 degrees, then once intake temps hit 150 it went down to 18 degrees. it didn't hit 150 degrees til the 1000' mark though. AFR is 11.6-11.8 the whole run.
Just thinking out loud I guess. I'll be installing 4.10 gears along with a new posi, that should help with my launch issues and get me outta the hole quicker. I'm guessing 5 tenths should be expected with gears and posi. current gears are 3.27's.
