I have an AEM CAI, and 5Zigen exhaust and only pulled 115 and low 100's torque. It was a mildly hot day (80's) and it was my 3rd pull. Could there be something wrong w/ my car? I mean, i know that an exhaust adds like next to nothing, but i would think i would pull like 120ish from what i've heard. Thnx

 

wow that is pretty low....sorry dont know what the problem is though....


does it feel sluggish?

 

i'm not sure, doesn't feel any different? could it be time for a tune up?? (48k miles) i replaced the plugs, rotor and cap and use synthetic

 

also do a compression check on all four cylinders, and how many miles is there on the engine?

 

Dyno really should be used for compairison, your results will differ from day to day and dyno to dyno. Make sure you are up on all your tuneup items, and make sure your cat isn't clogged or anything.

 

its got 48k, and yes i am using it for comparison to other cars of my nature. I just can't seem to figure it out!

 

ok, well i went to the track last night, and i ran a total of 6 times, and the fastest i went was 16.591 @ 82.21 w/ a .738 reaction time and a 2.498 60' time. Is this decent or not? i also ran w/ my 17's on and almost full tank of gas. These times were very consitant all night long, and the 60' were very consistant as well.

 

Well, the 17's and full tank probably hurt a lil' bit but your time should be lower. I pulled 15.4 at 89 with intake, header and a muffler. Your car is a stick, right? Look for at least 2.3 60 ft's for a decent run.

 

hmmm... well i think stock LS dynos at around 110 or 115 and if was a hot day then you have lost a couple of hp from that. What elevation are you runnin at? 16.5 is a little slow in my mind, stock LS runs 16 flat. I have AEM CAI, DC header, DC exhaust, and gears, and my best run at the track is 15.2 with full tank 17's and two 12's in the back............I also live in charleston SC where its 15 feet above sea level so............

 

do you have an auto??
