Heres a pic of mine and a pic of another Z with the same setup.

Hook up a Techtom or other OBDII scanner to really know whats happening to the inlet temps.

Search Google Compunurse - Cheap - not an Innovated Quality but better than a turkey baster Thermo.. Ha !

Ill have to do that. I have access to a Nissan Consult II.

Also, it does not accurately reflect the amount of heat that is transfered to the intake air duct between the MAF Sensor and throttle body.
Like you have always said. Thats the stuff that kills performance. (Even if it isn't accounted for on a open hood dyno)
To all,
Do what ever you can to keep that hot air from getting into your Popchargers or similar intakes. Hot air (at that temperature) hits performance big time!
I've seen that nearly all the Turbo and SC systems have intakes in the open engine compartment. If you can, rerout the air filter somewhere out of the engine compartment where it can get fresh air. Use large diameter silicone tubing if you have to.
Wraping your intakes like Dave did is also quite helpfull. If you could Iso therm your plenum and thermal wrap the intake system, do it. Your car will be happy you did.

The spacers for the 6 posts probably won't work because of the taper. I have the AAM tapered spacer and wasn't planning on using the 6 post spacers anyway. There's nothing there already, right? If you really want to use them, it might be possible to grind them down to fit.

The Aramid gasket will raise your entire plenum assembly just under 1/16". You might want to check the strut bar clearance gap on your current set up to make sure the extra 1/16" can be accomodated.
I'm setting up the GB now!

There have been numerous questions posed here, and all were answered except the two on dynos. I'm sure it's just an oversight. Has there been any dynamometer-based testing been performed on any of this material prior to offering them for sale? Please post the conditions and results/curves. Thanks

I purchased the 1/4" motordyne spacer in the last group buy and found it worked pretty good, based my my butt dyno.
Can you tell us how much more improvement the isothermal gasket and isothermal TB would have in approximate HP?
thank you.
