Lets see your racelouvers

[Ewheels]

It makes me happy to see people willing to cut holes into their brand new Mach 1

I don't know if you've done a roll bar yet, but drilling holes into the floor is another pucker.

For those that installed their Race Louvers. How did you handle the double skin of the hood? Did you cut out a larger area so you could access the fasteners? Or drill larger access drill holes?

I've cut cut larger section, I think this is what instructions are suggesting anyways. I am using nuts and bolts as I take my rain trays on and off between events, that wouldn't have worked without trimming extra "underskin"

Did you see any appreciable improvements in cooling after installing the hood louvers?

When I installed just the louvers, improvements were on a minor side. Once I did radiator ducting and opened up the grilles a bit, that is when it gotten a lot more noticeable. You need ducting to route all the airflow through the radiators stack instead of around them, and louvers help a lot to suck it out. They also give some more front downforce, which is another benefit.

I really don't think you want to be bolting through any double layers with air gap between them like RandomTask has done. Its a recipe for bending shit as you tighten (and it looks like his hood shows some of that), and those bolts may loosen over time. Those double layers just aren't strong once you've cut through them. Will it fall out of the car? probably not, but I don't think that's the right way to do it.

Best to trim the under layers back. If there are two layers sandwiched directly together with no gap, that's fine of course.

Well looks like I got some fixing to do.

its not the oem hood. I saved that, this is just another used hood I bought.

That being said, yeah i've done the roll cage amongst other things.

I could be wrong...

Man, so much presumptions....

I think maybe you are seeing some odd reflections, but its not bent, the bolts aren't tightened down, its to hold the vents so the stripe and PPF can be cut and installed. My question was rivets or bolts. if its bolts I was asking to clearance the hood, or drill holes bigger to access the nuts, or leave it alone.

But since you mentioned it, no the nylock nuts wouldn't loosen over time, since its sat in the shop with no bumpers on it.

The internet....so judgy.....

Don't take it personally. I'm not judging you, nor replying to your posts. Its all cool dude.

Also, I'm not saying the nylocs will be a problem on a car sitting in a room and not being driven and bounced around.

But that double layer thing... you can't torque those bolts or rivet through that, it will pull the top skin of the deck down and the 2nd layer will pull up. Not good!

Race louvers do sell a baffle kit I think if people are looking to close up the grill. I talked to those guys about it, it's not like it 'adds' downforce, but reduces lift. it's a trade off though between cooling and removing lift.

Yeah, I get that, I just felt a need to defend my actions!

So stick with rivets, clearance the hood, or drill the lower holes for access to the 10mm nut? What's your thoughts?

The rivet option was originally the plan, so I didn't clearance the hood - louvers shipped with the rivets, and that was my first plan, and they'll still be fine to use and not pinch the bottom layer.

Either rivets or clearancing for bolts should be fine. Both should hold it securely.

I think the little nylock bolts that shipped my [redacted brand] hood louvers were a lot smaller than 10mm and actually the side vents shipped with small bolts and the center vent with rivets IIRC. You can't even tell from the top except where there's a bit of shiny from a rivet that didn't pop off clean and had to be trimmed off..

See thats why I like the bolts, the short ones that I ordered are black and will look clean, but it will involve more work, vs no work with the rivets, but potentially the rivets won't look as clean IMHO.

Yes, but you would need to take out the louver every time you need to put the cover in, and at the time it was available for center vent only. Mine are attached from below and it takes 10 min to take them in or out without removing anything.

I don’t have a high quality picture yet but I just had the center vent put in. I’ve had the trackspec side vents for a few years now.

How effective were the sides only vs. The whole package?

To be honest I don’t have any real data to go off of like a wind tunnel and I never had serious issues with engine temps on track.
I do know that they are too far forward so blocking off the first 3 blades will yield very very minimal but positive results.
I have an event in 2 weeks so it will be my first time with the center vent.
Sorry I’m not much help there
