What Improvement Can I expect??

[araffio]

Few weeks ago I went to the track for the first time with my Maxima. I figured I'd run low 15's but was surprised at how poorly my times were. I have CAI, y-pipe, pulley, cat-back and Stage 2 VB mod.

My times were 15.89, 15.72, 15.72, 15.92, 16.16, 15.81. All my 60' times were in the 2.3 to 2.4 range and my trap speeds were in the 86 to 88mph range.

I ran with my heavy 18's, 1/4 tank 93 octane, full CAI tubing, full interior, & spare/jack/tools in the trunk. I also threw a KS code a while back which I reset and never replaced.

What kind of improvement can I expect on my times with the following changes for next time I hit the track:
-11lb. 15" Mazda Millenia wheels with Nitto 555 Drag Radials
-New Knock Sensor
-Hybrid Intake (midpipe only)
-Empty trunk, rear seats removed

????
Just want to get some guestimates on how much I'll improve.

this is probably out of my league as for as guessing, but if you change those things and get a lower 60 foot im guessing low 15's maybe 15 flat !

changing the rims and weight might make a .4 difference. and then bringing the 60 down would be another .1 or .2.. low 15's im guessing ?

LOOK AT THAT ENGINE BAY !
