And I answered my own questions I asked earlier today.

Well...this won't help in cooling the engine as it really needs no help and is regulated by the thermostat. These engines run pretty cool (water temp) actually at 180 degrees. Opening the fang vents should provide a little air to the Airbox intakes. There is no "Flap" so I'm not sure what you're talking about there. Water is NOT an issue. If you really want to improve things, connect the fang vents with the Pass through to the airbox for some forced cool air. DIY here: http://www.the370z.com/diy-section-d...ur-airbox.html

Strange - on my Z the bumper area where the air enters, and the left and right bumper areas where the intake gets the air from, are separated by a relatively heavy rubber flap that looks to be clipped on and could be removed.

This piece?......That is to the outside of the airbox inlet....

This morning when the car was first started, after sitting all night, the IAT was 5 degrees higher than the ambient reading. I would like to know if others have noticed this same temperature difference upon startup or whether my sensors are out of calibration by 5 degrees. One would expect the temperatures would have stabilized overnight to the point where they read the same.

No, this one. This is the view from underneath the car looking to the left. The bright spot is the fang opening and the flap can be seen to the left of it (if you click the image you can vaguely see the inscription "ET" on it).

Modshack-I believe you can see them on your last picture. On the right side of the windshield washer reservoir. From looking at your picture with the front fascia removed, it look like that the intake openings are closer to the center of the car then where those flaps are located, so I guess they do not hurt the airflow to the intakes.

They do not match exactly...

Still not understanding what you mean here...That's just the side of the bumper molding...
Here's a shot with the bumper off and one of my hose flanges mounted over the fang opening..

Steve and I installed my Modshack custom intakes today. Steve was able to powdercoat the intake cans to match PG. They turned out great! Steve was also able to machine the MAF tubes out of aluminum. Those turned out nice too. And the Cobb intake tubes look much cleaner than stock. They fit perfectly as well.

I still need to install my painted engine covers to match the Modshack custom intakes. I'll try to install them, take some pictures and post them up later.

can you feel any gains? Modshack if your MAF is to lean out the car, would I see any gains from it since I have the Cobb tune? Also would the cobb tube and your MAF fit with stock boxes?

I haven't really had a chance to go out and drive the car yet. I basically just drove home from Modshacks. The car runs great though with the intakes and they make a nice sound when you get on it.

BTW the Cobb tubes will fit on the car with the OEM MAF and intake boxes. They basically replace the OEM hoses between the MAF and the throttle body.

Looks Great!

Modshack, any plans to make a kit to sell to fellow forum members? I may be interested in your Maf's and intake cans (black would be my color preference)?

Thanks,

Thanks! I'm really happy with the way it turned out. :tup:

Here are some pictures of the intakes with my painted engine covers and ZeeToyz engine caps.

Where did you get those Z caps?

ZPirate 04-04-2010 04:01 PM

ZeeToyz. They just came out with the 370Z caps. I have the 350Z caps on my 350Z. Call and ask for Terry if you are interested. They have them in red, blue and chrome.

You can already buy air boxes for filters and maf's too.

LOL...Funny, John (Zpirate) and I discussed this earlier today!
Unlikely that I will for the following reasons:

1) I am not a vendor here and doubt the revenue I could generate from the various things I could design/build would make that financially feasible .

2) I am not real confident in the general mechanical skills of the members here. This set-up took a lot of hands on and slight modifications to turn out like you see it.

3) It would not be affordable. If I were to charge what I generally do for this work it would be too expensive. I could cut my margins, but I'm not interested in working for peanuts, in addition to supporting the inevitable issues that can/will arise.

4) This crowd is Dyno driven. My designs are more to improve day to day driveablilty. A few more horsepower at 7K RPM's is not what I'm looking for, but it seems most here are.

Zpirate is a local friend. I do his airboxes, he does my wills.......:-)

It sure did Steve. :tup: I hadn't even tried the engine covers until today.

Zsteve 04-04-2010 09:29 PM

Modshack with bolt ons and a tune would your MAF still be of use? Its to lean the car out some right? So is that still a good idea after a tune?

No need as a tune shoulld be making those adjustments....The MAF tubes are just mechanically leaning the car a bit as opposed to a programming change within the ECU when done by a tune..

On my drive home tonight I measured +6F over ambient temp. Not bad IMO. Sorry for the bad pic.

Hey modshack, how are the IATs at idle/standstill with the aluminium MAF housing?
The stock plastic pipe gets very hot already so i imagine things might be a little warmer with a metal one.

Old post, but if you set the car up to forcefeed some cool air through the Fang vents, IAT's will stay relatively low. I haven't had this car for a few years now, but I don't recall much difference from stock (on the material anyway)
