What exactly is the split on cars that you know don't need hood pins vs ones that do?

The last car I saw was a new edge that had a Kenne Bell 2.6, slicks and skinnies and a 6pt cage. But I better tell him he doesn't need those pins.

I'm not going to lie, my car will get hood pins of some sort before I hit the track, because new edge hoods are pretty flimsy, and catch a ton of air. That's pretty unsettling at high speed, and the results are disasterous. Of course I'll also be using PTFE lines, a scattershield, a plate for the fuel lines near the flywheel housing, and keeping the regulator ahead of the firewall and away from exhaust, per NHRA specs. But hey, I don't need all that, do I?

Actually when you put it that way it makes plenty of sense.

Plain rubber fuel lines will work. But lining them with PTFE AND a braided outside is additional protection. Like hoodpins.

A plain bellhousing and tunnel will work. But a scattershield gives you an extra layer of protection.

Your car doesn't need a driveshaft loop, the floor should protect you just fine, right? The loop is another level of protection, like hoodpins.

But counter to your previous point, a cowl hood can also help remove air from the engine bay, reducing recirculation and improving heat transfer.

Wicked, cowls inherently do not extract air. That's why cowl induction is a thing.

Guys RDY is obviously just upset that his car is not as fast as BAs, and mine, and babblebots old car because we all needed hood pins.
You should be more sensitive.

A load of X275 and ultra street cars go 150+mph in the 1/8th mile every weekend. I better start telling all those guys they need to install hood pins before they kill themselves.

Do I think PTFE lines should be required from the factory? Sure. The added safety definitely couldn't hurt. The manufacturers, with the NTSB, already did this with the latch though by adding the secondary safety latch.

Ok, your last point makes sense but for really any of our cars in this thread, that's a negligible difference. What happens if the temp drops below the thermostat temp? It closes and heats the engine back up. Hood vents serve the same purpose but do it better and you don't have this tall cowl in your face/view.

Have any of them even broken 12's in the 1/4? or 7's in the 1/8th? Been there, done that years ago with my little car. I'm making as much power as you and crack but over a thousand pounds lighter. The exception is the dumpsterfire once it gets running... which I'm still patiently waiting to see happen.

If i do a windstar swap, ill probly need to shave my hood, or go with a cowl.....

Not inherently, but a cowl with a big opening at the rear allows for more airflow to move through the compartment, same as it does on other heat extractor hoods, just in the rear. Same applies to many other trucks and cabovers.

Cowl induction is usually more due to design, where the intake seals up to the hood and the opening is only for the intake to draw in air, rather than the engine compartment, like on the early 70s Chevelles.

What about functional hood scoops, like shaker systems? I know we covered tmic's tho

Lol. The fox's butt wiggling is just right now. Thanks for asking.

How's your wiggle? : )

I've enjoyed this discussion. It's been good.

Like I said, there are a few exceptions to the rule. I didn't think about the new edge Mach's when I mentioned the STI or would've included the example.

Did he say it extracted air? No, he said it aids in removing air which is 100% true. Air flows in through the grille and radiator. Ends up circulating all over the bay before making it's way out the bottom. Add a cowl, and you have air coming in from the opposite direction, flowing over the engine, meeting the opposing stream, and making it's way out the bottom, while also keeping that frontal stream from flowing right back into the firewall. More air is being removed. When those two airstreams meet, they are going to expand, the air is going to be prevented from flowing upwards because of the hood, so the majority is going to go downwards pretty quick.

My opinion on the hood pins is they are "ricer" unless you have a real reason for them. I'm running a fiberglass hood on my fox and so far no issues. I've been only to about 105 in the car though.

I've had a factory hood roll up on me. No fun.

It has been a good discussion. And i was just wondering if thier was a seperate argument other then tmics

Only the stickons are true rice pins. Even if its done for looks, if thier real thier still doing thier job

Gahhh time to put away a massive of laundry.

Have fun with that

I swear, this motherfucker doesn't have anything positive to say unless it has to do with his turbo focus.

My hood shakes more than a bunch of preppy whit kids in the hood at night. It could use hood pins for sure but I never felt like drilling my hood.

Just takes confidence. And follow measure twice cut once

Or a dad.
I was scared to so my dad drilled mine for me.

Wimps.

I'm confused. I thought you said earlier yours weren't real?
