aziza z Posted January 18, 2011 Share Posted January 18, 2011 (edited) Never did update this thread. Heres is what i ended up with. After 3 track days, im happy with it (for now). Added brake ducts and front splitter as well. with brake ducts- before the brake ducts - grill still hides everything when its not on track duty- mock up - brake ducts (while it was under construction) front spitter (still needs to be finished a bit better, i dont like the current fitment)- Ill get better pictures for you guys.

I've been playing with this for a while, and I'm not convinced I've been able to get it to run any cooler than it does without any ducting whatsoever.

JMortensen Posted January 18, 2011 Share Posted January 18, 2011 You're running AZC brakes, right? If so, your vent should feed air into the center of the brake disk. I think the way you have it set up the vent blows on the inside rotor face, which can cause problems. Link to comment Share on other sites More sharing options...
Oddmanout84 Posted March 6, 2011 Share Posted March 6, 2011 (edited) I'll bite. This has been in the back of my mind for a long while, and just entered into my personal "skunkwerks" production last night. I had to do SOMETHING with all these empty boxes from Summit piling up!!! Its obviously not done, not even to the prototype phase. Plans are to make it out of sheet aluminium, maybe a fiberglass model. I would have liked to weld sections of it together, but I only have the ability to weld steel. So I'll probably end up using clecos, pop rivets and/or maybe some countersunk bolts. The intercooler as you can see rests on a piece of steel bar stock. This was the original way I mounted it when I first swapped the L28ET in the car. I'm retaining that bar stock, but cutting out the middle section inwards of the lower intercooler mount bosses. Then I'll reweld sections of it to the lower rad support in a triangle shape. In the void created, I'll be mounting a low profile oil cooler in a "V" angle in relation to the intercooler (clearance issues, especially with the -10 inlet/outlet). I'm also thinking about enlarging the hole on the right side of the radiator support (below where I pass my intercooler plumbing) to pass plumbing for a cold air intake. The filer will be about half the size shown protruding into the ducting. Of course, it will be sealed in. The whole idea of the design is to block off the upper portion of the grill as others have done, but also retain a stock look from a distance. So I've designed it to fit neatly behind the stock 240z upper grill. I originally was going to drill out the spot welds and remove the 280z turn signal brackets, but they work PERFECTLY for mounting this setup Edited March 6, 2011 by Oddmanout84 Link to comment Share on other sites More sharing options...
Zmanco Posted July 29, 2011 Share Posted July 29, 2011 So based on the testing on my setup, it made my car run hotter. Has anyone actually decreased their operating temperatures using a very small inlet with steep angles? While I think that some ducting can be helpful, it can actually hurt if done incorrectly. I made shorter ducts with less of an angle to avoid unwanted turbulence, os I hope I get beter results with this setup. Bartman, as we were discussing in another thread, I have a similar situation. What was the outcome of this second version of your ducting? And what did you finally settle on for a solution? Link to comment Share on other sites More sharing options...
Bartman Posted July 29, 2011 Share Posted July 29, 2011 Bartman, as we were discussing in another thread, I have a similar situation. What was the outcome of this second version of your ducting? And what did you finally settle on for a solution? My current setup is essentially identical to the cardboard mockup I posted pictures of. I'm very happy with the results and it seems to have noticeably brought down my operating temperature. In conjunction with the ducting I have functional fender vents with fans to force hot air out of the engine compartment, and I'm installing an even bigger 4 row radiator.
