I was wondering what other Greddy turbo owners are averaging for their "Intake Air temps"?
You need an obd II/Can tool to get this value. Only tools I know of are the CanScan, Scanalyzer, and autoenginuity.

After driving 20mins from work (fairly hard) I hooked up my CanScan and my intake air temp was 181F!
My coolant temp was 206F, which is average for me (185-210F).
This was with the car idleing for only a few mins to hookup my laptop after the 20 min drive.

I had a problem with my heat tape staying on the frame and lower part of the intake manifold area after 1 month of installing it. All of the tape has since fallen off. Has anybody else tried other types of heat shields?

Also, where is the intake temp sensor located?

The air intake temp is integrated in the maf sensor, so really it is not telling you anything except that your starting with some hot air! That temp doesn't account at all for the heating from the turbo. Sounds like the Greddy arinx needs to be relocated. I think Mazsport is doing this as one of there later mods, but probably wouldn't be too hard to do yourself.

So the sensor is in the MAF unit.
I switched out the airnix with a k&n type and also cut my stock intake box to enclose it and help in keeping the hot engine air out. Pics here.

Wonder if switching back to the airnix and removing the box will get lower temps. I'll see what people are averaging for their intake temps.

I am in TEXAS and the high has been at 100F lately.

I swear to GOD, if that friggin' machine shop doesn't finish porting my wastgate soon! :D I NEED TO GET THIS THING INSTALLED!! (had to vent to someone! :o )

Anyway, yeah. that stupid looking mushroom intake sucking straight from the engine compartment. I hope to get it sucking some cool air somehow. I like the modding of the stock airbox to keep it stealthy and get cooler air. I wonder if you could keep the stock airbox and have the suction tube just pass through to where the VFAD used to be. There's probably enough room for a filter there.

I'm interesting in the GReddy intake temps. I'll post 'em when I get 'em.

There's another member that did just that. His thread here.

I hooked up my Canscan on the way to work and did some datalogging to monitor the intake temp.
It was 80F this morning and after the car was warmed up I headed to work. The intake temps averaged around 100. Then drop down when it was moving to about 95. In traffic it would rise to about 110.
I did notice that the temp would immediately raise 5-10F whenever I would go into boost. I'm not sure why this is happening if the sensor is located in the MAF, which is located pre-turbo.

Once at work, I let it sit idling and watched the temps. Within a couple of minutes the temps were up to 150F.

One of the options with the interceptor kit is a temp sensor that will be mounted between the intercooler and the TB to give actual intake temps post turbo. I would really like to see what those are!

It shouldn't be to hard to have some piping made to add CAI to the Greddy. We just need something similar to what SFR does. Maybe if we get enough interest we can get someone to make the piping and get a group buy on it. I'd definitely be interested.
