I saw this car via CR.net (http://page7.auctions.yahoo.co.jp/jp/auction/g57592443), but this hood looks pretty interesting, and along the same lines of what's being discussed. Anyone know anything about it, except that it's in Japan?

That hood looks like a finished version of what I did. I like it.
|
I put my turnsignals back in, after running around since spring without them.
IAT and CLT temps are both slightly up. My overflow bottle even gurgled a bit yesterday after shut down. My conclusion is that the fresh air afforded by the open turn signal locations offers some cooling to the motor itself. I am not convinced that TSI type intakes without additional hood venting is a good idea, due to the fact that it would decrese the pressure delta between the front and rear of the radiator/intercooler sandwich. However, a TSI style intake + vented hood seems to be a good way to go. I would like to also try a NACA headlight lid. But I don't have one. B |
That makes perfect sense to me. :D So are you still running around with blue franken-hood on? or did you create a finished hood from your original?
|
Yes, my hood is blue. I still need to add another vent over the turbo area, similar to what you drew up. I think that was a couple pages back in this thread.
My dad's buddy owns a body/paint shop, and if I can make the hood look presentable, he'll paint it for me for the cost of paint. Which if I get him to do it at the same time as my hardtop, that's basically nothing. So I think I'll have a summer hood and a winter hood. Of course, you're welcome to try the blue hood out any time. B |

Of course, you're welcome to try the blue hood out any time. I'd like to, but then I'd have to install a hood latch. :gay: |
My car is gray, not silver. You'd be pissed.
Yours is silverstone 2 stage, is it not? |
It was when it was new. I got it after a repaint from a demolition derby on 285... that's why it was the cheapest Miata in the classifieds... ten years ago.

On friends S/C car I put a thermocouple under the passenger side of engine compartment by the fuse box and we went for a drive. On an 80 degree day the air was as hot as 130 degrees by the fuse box. Removed the blinkers and temps dropped to 102 degrees. Since then we put 2 washers under the back side of the hood hinges and removed the rubber gasket between the cowl and hood. With the hood shut you can see into the engine bay and when you're stopped the heat is just POURING out of the cowl now. Haven't taken temp measurements since then, but just wanted to share our results. Blinkers: I bought some 70,000mcd yellow 10mm LEDs off ebay, soldered on resistors, heat shrink, then wired them into the blinkers. Remove the metal clips that hold the stock turn signals in the bumper and run a 3/8" twist bit through the plastic on the bumper. That'll make the hole about 1/32nd larger than it was and the LED will VERY Snugly slip into those holes. The way I wired it was with 2 LEDs on each opening, the outside were wired to blink, the inside were wired to run constant. Works great! Hooked the side marker up to blink too. |
pics?
I saw the heat pouring through my hood last friday while stuck in traffic. :eek: |
Yeah I'll grab some pictures as soon as possible. Its pretty cool. :D
I think the car looks a lot more aggressive without blinkers. |
juan, does this car have loggable AIT and CLT sensors?
at speed, in your OPINION, does air enter through the turn signal area, and exit out the back of the hood? |

I would like to also try a NACA headlight lid. But I don't have one. B I can not remember if the topic was Fans, Rads or Extractor Hood. |
I can guarantee a Miata needs holes in the hood when sitting in traffic after being in boost.:firedevil:

i dont see how the raised hood hinges would help. as i heard before and was stated before, they let air IN, not out. plus to cool your engine, you would want air entering through your radiator, not other places. in my opinion, the thing that would work best is get an actual extraction hood that let hot air out after the turbo, this would cool the turbo since it is still cooler than it.
i think this hood and keeping your turn signals in would maximize air flow through the radiator and past the turbo/engine etc. i dont know much but this makes sense to me. http://flyinmiata.com/index.php?dept...0%20%201990-97 |
i just read the testing of the hood i stated above and it proves my theory, plus it looks bad ass. sort of expensive, but totally worth it in my mind.
if your bored, read this. http://flyinmiata.com/projects/CF_hood.asp |
$600!! For that price I can afford to replace my overheated engine. =)
|
good point but it looks cool. lol
|
No doubt raising the hood hinges works great when sitting at a traffic light with an engine bay soaked with heat. I suppose that's fine if it doesn't cause cooling problems at speed- and you don't mind the "jacked hood" look.
There's really two issues that can both be solved independently but will impact the other. The trick is to use methods that improve both issues. As proven by FM (and Ben and anybody else using extractors...) extractor holes/vents in the hood work at speed and work at a stop to vent the heat. I'm still waiting for somebody buy/install one of these and report back...anybody? |
