You need more time to allow the mixture to cool the air charge.

ARD does it right IMO.

It looks to me that at 150 g/s the air is moving around 24 m/s through each bipipe.  18" of extra travel equates to 0.02 extra seconds.  At 200 g/s about 0.015 seconds extra contact time.  I wonder if the extra time really matters.

Installed the kit, will post pics tomorrow.

I mounted my nozzles down where the flat area starts on the bi-pipes where the air charge 1st enters from side mounts and running 400ml/min total and intake temps went from 100* and climbing near 140* off the w/m. To 100* down to near 67* on WOT pulls (at night). Just gonna tweak timing in the next few days. Will post logs tomorrow after I get some daytime logs when its hotter but drier out. It is super humid tonight.

The outside temps here in Florida been low. I got some logs when it was 70* degree's out.

Seeing some good results. Same tune as before thats posted. 50/50 mix of w/m dual 225 ml/m nozzles and 93oct. Logs attached below, one log I thought car downshifted out of 3rd so you'll see TPS go 100 then drop and back to 100 this screwed with results a little. The full solid 3rd gear run was done good. Car runs alot smoother on w/m and had to add in check valve and throttle response came back.

**Side note question, how do you setup me7logger to output seperate files each logging session? Mine keep going into the same file and add in a few rows down.***

These logs make my car look slow, Calc TQ looks close but HP never does to me, I have input as much of my cars data into ECUxPlot. But it isn't slower that's for sure, can someone else please open them in there copy of ECUxPlot. I'm using the newest copy and the car is a 2000 A6 2.7T.
