Hi guys,
I got the raw data from the G35 dyno day entered into Excel. The plots are looking really good. Gains in HP and TQ all across the entire RPM range! Hi, Low, Mid, Everywhere! I will get it posted tomorrow. There are many plots!

Do you have any plans on upgrading you exhaust? If so, get just a y-pipe. Install it, get used to results and than install spacer again, just for the sake of experiment.
The only mods I had on my sedan prior to installing 3/8" spacer were y-pipe, z-tube and grounding kit. I'm really impressed with the spacer and my observations seem to be in line with what many other people reported. I think stock intake and exhaust are pretty well matched and when upgrading things it is important to try keep that balance.
Good luck.

I am really confused on why I had the experience I did, and everyone else is so happy with it. I really would like it to work on my car. 8 - 10 HP for $135 is a pretty good deal considering other options. I installed it correctly, and everything seemed to be perfect,,, I just didn't get the results you guys did. Maybe I'll try it again.. I don't know. Sorry to be a post Wh@#e

Dizz Dynos
These are the results of the recently performed dynos on a 1/2" Motordyne spacer. The spread would have been even higher if the dyno operator didn't cut the runs at 5900 rpm.

I was able to get the engine cover back on with the 1/2 inch plenum spacer.
I removed the gromets and the rubber washers from the top holes of the engine cover. I then inserted the gromets back into the holes from the bottom of the cover and slipped on the rubber washers onto the gromet from the top of the cover. I then placed the cover over the plenum and screwed it in. The hood won't drop shut, you must slam it down a bit or just push down slightly and the hood locks down.
