DC headers= Loss of TQ?
DC headers= Loss of TQ?
I drive a 03 SI
I just installed a dc ceramic header into mty car, i also have a CAi injen intake. After i installed my DC header, i noticed a considerable drop in TQ. Is this normal to see?? do i gain any thing from installing the headers like HP gain? cuz i dont feel any. Ne of you guys out there have ever experienced this? Im thiniking of puting back my stock. is this a good idea. or any ideas how to get my Tq back?
Thanks guys
oh yea i found this at an import tuner webside, looks like the same happened to this car too.

Man I looked at the link and see what you taliking about.
The dyno results do show a drop in peak torque.
weird.
here is the end resoluts on that link
performance chart
HP Level HP+ TQ Level TQ+
B Baseline 153.3 * 131.9 *
1 K&N Air Filter 160.6 7.3 135.3 4.4
2 Tanabe Exhaust 163.4 2.8 134.8 -0.5
3 DC Sports Header 166.9 3.5 129.7 -5.1
Final 166.9 13.6 129.7 -2.2

trade off of torque for hp.
u can't feel the hp cuz its 3-4 hp according to import tuner (hardly a sound fact, but yeah whatever)
the fact that their baseline test was like 153 hp kinda makes me raise my eyebrown...
do u feel the torque lost that much? if so ... u might want to consider switching back to stock.
stock parts are usually always tuned for torque, and not high end hp... well, some cars anyway.

i thought it might be just a lose of torque in the low end, cause thats what it felt like when i first installed my intake, but i also have the same header so i guess i see if my low end torque goes down more when i install it
