OK, first off I do not have any 1/4 runs with it yet since installing it. Only been home a week and have other crap to get done before I get to track. Anyway the best I can do at this point is compare my 0-80mph logs. Looking back at my previous scans at the track my IAT's always peaked around 100mph then started to drop, I would attribute this to the Meth. On to what I have observed so far.
With similar outside temps on my runs at the track last year I would see a 26-28 Degree IAT climb from 0-80, now with the spacer I am seeing a 15-17 degree climb. My cruising IATs before were 15-18 above ambient, now they are 8-12 above.
I did loose about 3/4 lb of boost, I believe this may be due to the fact that while I had it all apart I also port matched my lower manifold and cleaned it up.
As for driving impressions, it feels a bit more responsive and mid range feels stronger. I cant say that I notice much more. It runs as good if not a tad stronger then before even with the loss of boost and being on the rich side. ( changed around some fuel system stuff) Due to it being rich I also turned the Meth down a little so I expect slightly better gains once I have a chance to work on the tune and set the Meth back where it was.
Since installing the TVS last year I have ran it on my setup from 8-12lb, I have noticed hardly any change from 8-12lb in IAT's so I am going to rule out the 3/4 boost loss as having a role in IAT's. I am going to raise the boost some more shortly and will be willing to bet IAT's are barely effected. I am not pushing the blower close enough to its limit for it to be that sensitive at this point.
