Hood Pin Recommendation.!!! (1st post picture) - Page 3

Hey I was wondering, why do you guys need hood pins for CF hood? Are they that light that they have the potential to fly off during high speeds?

msm_ching · 10-26-2009, 04:35 AM

to me, They are lighter. They seem tight to me when its closed.
but then, everyone, and its really everyone's telling me that its better to have it on.

everyone stands for => people who has a modification shop, people who knows about modification.

Your car will look great with the hood on, your Panda theme is well done. I just think you need some gold wheels, to take up the mantle where Fuji dropped the ball... haha.

haha, well the gold wheels lasted for a good bit, but when the deal on the RE's came by, I couldn't pass it up.

Also Cyn, yes CF hoods would have a tendency to fly off at high speeds...under a few circumstances.

1) Most "CF" hoods that are mass-marketed, i.e. Seibon, VIS...are Carbon-fiber overlayed onto a fiberglass skeleton. The fiberglass being the heaviest part, this makes for a lighter than stock, but still not super-light hood. Because face it, most people buy CF hoods for the look, I know I did. With that being said, more expensive hoods, i.e. Fiber Images, J's Racing, Feels, Mugen, etc, not only is the top portion of the hood CF, but the structural part of the hood is CF as well. This makes for a SIGNIFICANTLY lighter hood compared to a VIS (or equivalent hood) hood, let alone a stock hood. So as far as people saying "yes, a CF hood is so light that you NEED hood pins"...Unless you've purchased a dry, 100% CF hood, you can ignore them

2) The TSX, in no way, is fast enough to be able to achieve speeds where the hood would fly off. Simple as that. And if your tsx DOES get to the point where it flys off because you went too fast, you can use the money from your newfound sponsorships to buy a new one.

But yes a hood can fly off if your hood is too light and you are going too fast. Observe this E46 M3 with a Horsepower Freaks turbo kit that races a GTR. (Also notice the GTR kills it at the launch, but the M3 catches up)

Wow! That's crazy! At least the hood didn't smash the windshield or even do any damage to the body.

hood latches have secondary catches already

Hood pins are used for those who get the mock up cheaper versions and they don't like seeing the wind lift the hood while driving. Additionally, if the hood is not molded properly allowing for unnecessary lifting, pins really become a necessity. Most of the cars at shows I have seen along with my old prelude had the hood latches removed completely for weight reduction. So yea, they do serve purposes.

OP, I've always used the flushmount pins from aerocatch. Last pair lasted from 2006 til August this year when the engine caught on fire and disintegrated the fiber hood.

I still have an extra set at home in its original box. Send me a pm with an offer if you are interested in them. They are the matching carbon fiber overlay of Seibon's pattern.

I have the J's Racing hood and the bottom I am pretty sure is still fiberglass not postiive cuase it is completely smooth and I cant see the material however the top is just a single layer of carbon fiber that is it. The hood weights half of what my TCSportline CF hood weighted. That hood I would say only weighted 1/3 less than my oem hood which I have to say the OEM hood is extremely light compared to the hoods on older cars say before 2003 even. Cause the hood on my 2001 CL-S weights significantly more than my 2004 TSX OEM hood.

All this being said I still have not seen a reason to run hood pins all though I have considered it with the J's racing hood because it moves a lot more than the TCSportline hood. I want to do aero catch as well actually howver if you look at our hoods they curve a lot right at the end which will make fitting those pins extremely difficult cause there fit tolerance is very small.

So with all this said, if you make sure your hood latch is adjusted right and is tight and you make sure the rubber bump stomps are set correct you should not have a problem at all.

Jason -- CL-S hood is probably also noticably larger than our TSX hood, no? Since it's a coupe, it likely has a longer hood. I'm too lazy to Google for pictures, though.

I actually went ahead and got myself one already... Thanks for the offer tho!! =)

lol.. You should have come earlier and let me know about that.!!! Because i bought the aerocatch flush and realized that it has that problem. (curve at the place where the flush pin can be installed.) Everything can be custom, but the labor is too much. I got quoted for $300!!! ==.

________________________________________

And lastly, my vis hood seems to be holding well enough to NOT install any hood pin.

HOwever, i thought MAYBE it will look good with the regular hood pin. (since i have one already).

I regretted having it installed later on with the regular hood pin.
but then, after i look at it every single time, they seem OKAY to me now.

i'll go take a picture and have it updated one the 1st post...

btw, what do you mean by rubber mount??

and.. is it necessary to install the stuff under the OEM hood to my VIS hood? (the rubber pieces, the insulator?)

you do what you want to with carrying over the shielding and whatnut

But the rubber mounts he speak of you'll see on your core support bar, they can be twisted to move up or down since most ppl dont like fabbing their hood latch up and down.

i THINK i know what is it.. and lol, i m not sure if its still there.
but, i don't think installing hood will have to take off that thing ehh...
