Ok.....that was a pun. ADTR sucks....alot of air! I got the test-fit intake yesterday from Hector, and the performance gain was amazing, even considering my heavily modified stock airbox. Much better throttle response, and not alot more noise. My supercharger whine is more evident, but that'* MUSIC, not NOISE. The REALLY amazing thing is that I'm making these observations BEFORE my PCM has time to re-learn the AFR curves. Right now, the car is still running lean from the change (I used my scantool to verify my suspicions on this). A few more miles, and it should settle right into the performance curves
Absolutely no question that this would be a serious performance boost from a stock airbox and paper filter, and I saw the difference from a vented airbox with a K&N!
Now for the OTHER part. The Series 1 SC is apparently different in fit from the Series 2 NA. The 2na has an angled upper intake plenum that sets the TB pointing forward slightly, so it needs less angle in the mandrel bend of the intake pipe. The Series 1 SC comes straight out, and therefore needs a slightly more extreme angle in the pipe. The good news is that all I had to do was trim the silicon reducer to that angle, and PRESTO! Perfect fit. Another difference I found was that the Series 1 and Series 2 IAT sensors are different diameters. I simply increased the grommet size from 5/8" to 3/4" to make mine fit.......and the other good news for Series 1 is that the stock IAT harness will reach the filter, so there'* no need to buy an extension, make an extension, or mount the sensor closer to the TB. It goes right where it should!
Here'* a bunch of different views. If you look closely at the Silicon reducer on the TB, you can see the angle I trimmed off of it to make the fit more comfortable. I'll get working on a heat shield this weekend (I already have the polycarbonate).
