Adamant's QS Exhaust Install - LotusTalk

adamant · 12-03-2004, 01:50 PM

I'm happy with the exhaust and I am trying to upload the torque and power comparisons but I may have to make them available another way. Anyway I have uploaded a 20Mb windows media format of the exhaust on a dyno jet . The sound quality is very accurate. The background noise are the fans keeping the engine bay and radiator cool. I think it does not sound all that loud but I leave it up to you to decide. :P

I am going to upload the torque and power graphs locally so at least I can add them to this thread for now.
let me know if anyone wants any further details

BTW sorry this has taken so long.....
The 20Mb VIDEO is here (I wish I knew how to do this correctly

)

It lost a little HP and TQ, but saves weight. It's a wash. You gain a cool sound.

Did you make both runs the same day? Did the ambient temp change much?

If you follow the curves in the torque graph you can see that there is fractionally more torque with the QS. Only the peak is a bit less. Thta highest number run was hte last on the QS and it was pulling more. In the stock the third run was giving less.
The runs were done on saturday a week apart. All the runs are SAE corrected for pressure humidity etc.

I love the sound!!!
