here is what he has 1999 civic si
skunk2 stage 2 everything in the head,
skunk2 intake manifold
upgraded fuel rail and fpr

now he went to the dyno jet to get his car tuned,
he ran a 15.9@ 88mph - 1/4 mile
and put down 200 CHP
160 whp
100 torque

he hasnt upgraded the fuel injectors and i know he is going to raise the compression this coming winter.
is the reason for the low numbers because of lack of spark, fuel and compression?
I mean stock si's can do that 1/4 time

thank you for your time and please no flaming just looking for advice/opinions

 

thats a good amount of mods to the motor... i think your friend just needs to learn how to drive a lil better. also, track conditions can drastically change times. what was his trap speed, his 60ft. times?

 

im sorry i forgot to mention this was all determined on a mustang dyno.
