The Drifting Miata

2016 D1 Boost Series Drift Comp Rd. 1

I grabbed third gear on the second run and the stock clutch didn't mind haha

your hood and tires are broken.

Tires are definitely broken, hood is not. I have spacers because I like the look and for more air flow.

More air flow to where? Science has proved that does the opposite of what you think it does.

Yeah, the hood is broken. That's a high pressure area, and is interfering with airflow through the radiator.

If you drove the car proper it would probably overheat, but you only do panzy 30 second runs anyway.

YOU broke the hood.


anyone who likes to look of a broken, non-function hood is a ******* moran.

You guys are quite the friendly bunch. I only drift the car right now and its towed to events where it does an equal amount of idling time as drifting time. The idea is the natural convection needs somewhere to escape so it makes perfect sense.

Air tends to move from areas of higher pressure to areas of lower pressure.

The area at the base of the windshield is an area of high pressure, which is why every auto manufacturer uses it as an inlet area for the HVAC system. It is also why many auto manufacturers source inlet air for the engine there (see cowl induction). By rendering the rear seal of the hood ineffective, at speed the air is coming in through the rear of the hood into the engine compartment, raising the pressure within the engine compartment and reducing the airflow through the radiator. This reduced airflow can cause overheating.

3 things...

1. Car is never really at any kind of "speed" for long
2. Car is at angle when at speed
3. I have an intercooler in front of the radiator (I'm sure that is waaay worst for the sake of this discussion)

With that said, I agree with everyone's argument. It just doesn't apply to my uses.

P.S. What about the low pressure area under the front crossmember? Even if there is high pressure coming in from the base of the windshield,will it not exit to the bottom of the engine bay?

Regardless of everything you've posted, the car will work better in every way if the rear of the hood were NOT on risers.

Simple as that

I disagree. I guarantee the under hood air temp is lower with the hood raised in the rear during idling. Answer this - Is the engine bay air temp higher with the hood on or off?

Who gives a **** about idling. You want it to work when you are actually using the car. If your **** is overheating while idling then you have bigger problems.

Props to this guy for driving his car instead of armchair racing his EFR...

Dude, you can't just "Opt Out" to physics.

no, answer this: why do you care about under-hood temperatures more than coolant temperatures?

because who cares what's happening inside the engine, duhh.
it's what's happening in the bay that counts.

you don't overheat an engine

you overheat the bay

What this forum really needs is a filter that automatically bans anyone that uses "Drift" in their user name or subject line. Think of grief it would save. , admittedly we'd loss some entertainment value but a worthwhile trade me thinks.

we used to change drifting to buttsexing.
