Just use 4 bolts under the hood for the bumper, and cut the point out where it bolts to the fender and replace it with a quick latch like thing. Something like these but smaller theres plenty of options.

I used 4 dzus fasteners along the top edge and then one on each corner with these brackets attached to the fender. Has held up that way for 2 seasons but it's just the bumper skin.

Why is the hole not a gaping hole?

Its kinda making a wing shape with the top of the hood and the top portion of the Radi duct. I talked to Paul (plucas) about it and he recommended a low resistance flow radiator https://www.miataturbo.net/attachmen...ine=1370143040 https://www.miataturbo.net/attachmen...ine=1370143040 https://www.miataturbo.net/attachmen...ine=1370143040 |
I'm referring to the hole in the front in front of the intercooler.

Finally took this out,
Monster grip, very very stable. Happy days. Turbo setup held up good also. In, passed scrutineering no hastles, drop the tyre pressures on the slicks, check, double check, triple check. Out for qualifying, first lap out, first time down the straight the splitter failed. I tested it to about 150kg jumping on it so I was amazed, when he came in a quick check showed that it generated so much downforce it tore chunks of steel out of the bodywork! http://s24.postimg.org/nnalzjlyt/20130601_104609.jpg Here is a piece I retrieved from the other side. https://www.miataturbo.net/attachmen...ine=1370144644 Its held on with 6 bolts and only the front 2 had issues, so lesson learned, the splitter is way way more efficient than Id even hoped so it was remounted with a temporary but strong solution. So great news about the front aero design, also looks like the cooling issues the car has always had have been solved with these recent changes. Here is the excel series and the pulsar series in together. And a few pics from the field. http://s24.postimg.org/52qz67px1/20130601_095653.jpg https://www.miataturbo.net/attachmen...ine=1370144644 http://s24.postimg.org/ka6yqkhrp/20130601_121029.jpg Dann |
OK so a triple post but that is a good looking track Miata. I mounted my splitter to a steel structure that bolts to the factory bumper bulges (bumper bulges been removed)
|
Fuck me, can someone please fix the TP.
I didnt realise, I was having trouble with firefox, using chrome now, swore I never would. Thankyou mate, this was remounted using the factory weld nuts you can see in the first photo. Thanks Dann |
Also the hole has to be smaller than the surface area of a cooler because if the coollers frontal area is 50% metal, 50% air holes then it will only flow 50% of its area wont it.
Dann |
Oh i see. Well you learn something everyday. I always thought you wanted more pressure in there.
|
No it doesnt need to be smaller but thats why it can be, My apologies.
Im fairly certain making it larger doesnt do anything because there isnt more pressure just a boundary layer. Dann |

Nice work Dann.

You are a LOT of my inspiration Dave. Dann |

Your thread was my inspiration to build mine. :party:
Regarding the heat exchanger intake area: The reason you want the intake area to be about 1/3 of the frontal area of the heat exchanger is due to bernulli's principle. The efficiency of a heat exchanger is affected by the pressure differential across it. Bernulli says that when velocity decreases pressure increases. So if we have a small opening with ducting that opens up behind it, the velocity will decrease as the cross sectional area of the ducting increases and it will create a higher pressure in front of the heat exchanger. Regarding your torn out splitter mounting points: why not use those nice reinforced threaded holes just above the holes you used? Thats what I've used to support my similarly sized splitter for years without any problems. |
Thats what I ended up doing..
i dunno.. I dunno. Anyway lesson learned and thats the important part. Dann |
