Anyone have the X35 spacer installed yet?

I'm curious to see what kind of difference the spacer is making for the 3.5. I installed a Mishimoto J-Line intercooler on my Ex Sport and it has helped with temps but I'm further seeking temperature reduction.

I don't know of much of a difference I'm still unsure about it to be honest. Back to back 3rd gear pulls same road and same tune before and after the spacer I was down according to virtual dyno I was down a lot in power....like way too much for it to even make sense...before I take spacer above numbers and after is below.

At the track and after 3 hours of driving I let the car cool down with just the hood open for about 45 min then 3 bags of ice for about 30 min, first run ran 11.90. Hot lapped it(went back around to go again with no cool down) let the car idle for 15 min waiting to go IAT2 got to about 147 and stayed there...then I ran 11.67...with the car considerably hotter....so idk.

I have some dowels now that I can install to align the spacer dead nuts and there is a little bit of a transition from spacer to manifold so if I port them to match then we'll see. But so far I'm actually worried it's decreasing performance.

What's going on with the blue line? Either way that doesn't make much sense that you'd be down in power.

Thanks for your input, seems like there isn't much out there on this and it would be good to see before and after dyno.

I have quite a few 3rd gear logs that look like that on Virtual Dyno. I think I'm doing the log then slamming on the brakes is probably what that line is doing. I have lots more tests to do. I did have so a 2.10th better launch though for the 11.67 but it was much hotter. Lots of folks contend it has to help so not sure. For me anyway it appears inconclusive so far.
