Here is a comparison of a vehicle running a FUJITSUBO Equal Length header with there up-pipe. We swapped out the header for our AMR Header and AMR Up-Pipe.
Now, as you all know the 2.0L does NOT have AVCS. So we are unable to increase spool characteristics what-so-ever. The spool rate is what-it-is. The customer can also do his own logging to see the comparisons himself.
Timing was dialed in equally.
Air / Fuel mixtures were dialed in equally.
Both tunes were from the same tuner under the same conditions.
This also shows that though a header has smaller diameter tubing, it does not mean it will increase spool. |
