I'd say heat soak in the engine bay raising the air intake temperature causes the real issue. Oil temp isn't really the issue but people associate the two because the temps often move together. Heat soak is much more of a problem on the street than it is on the track, on the track you normally have enough air moving through the engine bay and enough air moving through the intakes to keep temps reasonable.

The following is what most people experience on the street. Start up the cold car in the morning, drive for 10 minutes conservatively while it warms up. When they see the oil temp has hit 180 they go for a bit of a sprint, power feels good. Slow back down, sit at a traffic light for 2 minutes, engine bay temps climb, intakes and manifold temps climb. Go to take off from the traffic light and instantly feel the loss in power.

Not sure what the best solution would be for the street. Insulating as much of the intake as possible might help resist the heat for a little while, at least until you get moving again at highway speeds to cool things back down.

Biggest thing with engine bay heat is extracting the hot air.

A vented hood should work pretty well. If you had the space (which I don't think the Z does) you could actually use fans to help pull air out of the engine bay. Who knows, there might be enough space in there to rig something up. But at the very least, a nicely vented hood should help quite a bit!

You're exactly right. That is a very common situation for me. So I am trying to keep the engine bay a bit cooler. I'm trying to avoid having to get a vented hood just yet and would like to maximize what I can do now. Also, although I'm not really all that worried about water getting in (and concern has grown since the SC installation because there are somewhat exposed cables now) it does make a mess of things inside the bay when the elements can seep in.

I was thinking about lining the charge pipe with gold foil to keep heat from radiating everywhere else. I'm only hesitant because that pipe gets really hot...just need to find out how hot. Im guessing under 200 degrees so I'll be fine with the gold foil. Also, maybe lining the new intake manifold with foil can help keep heat out of it.

The gold foil is best at reflecting radiant heat (i.e. keeping heat out), not sure how well it would work at keeping heat in as that heat would be conductive not radiant.

EXACTLY, I thought about that and the answer would be to wrap in some kind of header wrap type material. It would look ugly though...I'm talking to the guys from Heat shield thermal insulation to see what they think...

What about some sort of insulating coating? Like ceramic or something to keep heat in?

EDIT: Found what I needed.

I strongly recommend mounting this to your hood to solve your cooling issues RCZ. Dont worry, I wont charge you for my mechanical recommendation.

I am awaiting arrival of the SC (FedEx says 28th)!! I was just curious what are your current specs for your alignment. Do you think you need to make any changes to alignment because of the extra power? As of now my alignment is a tad bit negative then stock spec. I was thinking of returning the rear back to factory spec just to get some more tire on the road. What do you think?

get some gold tin foil and wrap everything. bling and good heat rejection

Haha, I'll put that in the maybe pile.

I'm running very negative right now and its fine. I guess I could use a bit more traction in the rear, but in all honesty I'd rather have the cornering grip since straight line acceleration can be modulated a bit and its not all that bad with my NT05's. If I had the stock tires on, I'd probably be suffering a bit right now.

I found a company that does coatings that can reduce surface temps by up to 400 degrees. That should do it.

LateralG'z

What your take on your current tires?

awesome tires. grippy and predictable.

MightyBobo

Whatcha running right now? Im going to need some tires this winter probably

Here you go. The dotted line is a random run we did while tuning a few months back. Its just for curve comparison purposes...



iCarbon, they are taking their time. I'm starting to think I should get it done myself....

I have been out of the loop for awhile. Kit and car look great!

Anyways, I couldn't find a dyno sheet anywhere. Any way you can post one?

How's the iCarbon thing going?
