3800 drag racers, i need the 411

Without knowing my 60' times and with my current mods:

3.3 press-on pulley
Autolite 104s gapped@ .053
Gen 1 - 1.9 rocker arms
3 inch mandrel bent custom downpipe
high flow cat
Pector PEMs
3 inch James Dean custom exhaust with stock mufflers
Thrasher CAI with 7inch K&N
DHP v1.0 PCM
180 degree drilled thermostat
U-bend/resonator delete
flipped front motor mounts


What would cause these unusual ET's?

14.66@101MPH - run 1
14.23@105MPH - run 2

106 not 107 and you backed it up with consistant 105s and 104s mostly
mike dont trust thos things. most people have one thing really off. like 60' or 1/4
i would guess those trap speeds are a little off. i bet you trap closer to 101 not 105
with those mods.
those things are about as good as air/fuel ratio gauge on a narrow band
but if those were real runs it looks like you would have had a 2.8 -3.0 60s
real pro like driving

I'd guesstimate 13.6-7 on a good launch with those mods...trapping 101-102 is about right. With those things you need to be on very level ground to get it close to accurate. I have a different brand than yours, it was close on ET, but always off on MPH. I once ran a 12.8@150 on it!

LoL - 150 mph!
I was messin around under the hood just now and noticed there was tinfoil stuck on my K&N airfilter! I rigged it up for heat insulation this afternoon and a LARGE section of the foil was wrapped around the cone for my runs! It was sucked so hard that it conformed to the shape of the filter! I wonder what my MAF readings looked like. So probably it was the tinfoil stuck on my cone filter causing the low ET's

Chad we're gonna have to race

I was performing some intake mods and wanted to get some baselines. Tweaking the intake doesn't warrant a costly $100 (approximately) trip to the track for official et's. And the GTech is pretty fun. B)
