Vented hoods and turbos
 

I thought I had kept an eye out for this but does anyone here with a vented hood have some pics of how this lines up with the turbo and motor? I want to see how rain may be able to get in and look at options to get all this heat up and out of the engine bay.

If this has been discussed, please point me in the right direction and kill this thread. :bonk:

Off the top of my head, I believe @Supermassive has a vented hood and P&L Turbo Kit.

Edit: Yes, he does

Well I was hoping to see some others post here but it looks like @Supermassive is the only person with one.

I was looking more at these hoods with the vent almost (?) over the gap where our turbos are mounted.

The DV looks like it has better ventilation since there are two areas for the air to escape.
Either one would be painted to match the car.

I have the VS hood and it vents the heat really well. The vent basically sits right on top of the the turbo. Here's a pic I took after I I stalled the hood. For reference the drivers side is to the top of the pic and the front of the car is to the right of th pic. The gold at the bottom is the intake pipe and the turbo is towards the top. Hope this helps.

I'm about to cut a giant hole between the engine and radiator in my hood to extract excessive pressure in the engine bay during race conditions. It's more about allowing air to flow through the IC and radiator and then releasing that huge volume of air seen at high speeds. Given how well sealed up the bottom of the engine bay is for aerodynamics I'm seeing a lack of flow through while racing. Hood vents will allow the IC and radiator to work more effectively and you'll also end up with more front downforce.

The aftermarket hoods are vented conservatively which is fine for street guys and will still help substantially.

it seems that all after market hoods are carbon fiber..any aluminum ones or anything or am i going to have to cut up my own hood?

I can't remember if you're back in the country with your car again or not. But can you get a few pics further back for scale? Maybe leave a light from your phone on so it illuminates up from that area? Anything further back showing how the vent and engine line up would help a lot. :happy0180:

I am back in the country, but on leave in TX for another week. I'll get the pics you requested when I get home!

The only real concern I have with a vented hood at this point is sitting in traffic in the rain and getting my turbo blanket and wrapped downpipe wet. I would be willing to cut my OEM hood to add some vents if there was a vendor who made a kit with good directions and templates. :thumbsup:

What about hood spacers? I know people generally hate them as they leave a gap at the rear of the hood and looks like you just had an accident and didn't mend it correctly....

I would say the chances of anything getting wet underhood are less with hood spacers vs a vented hood though. Would be easy to test real world application with a trip to the hardware store for some nylon/delrin spacers and a temperature sensor

Would removing this weather strip allow some air to vent, similar to raising the hood?

I heard that removing that strip was one of the things the VCMC team did to help with the cooling of their Full Blown kit. I have been meaning to contact them to see exactly what they did.

Looks like it might be an alternative that doesn't alter appearance of stock hood, I wonder how big the gap would be compared to a spacer

If I remember correctly they just removed that entire plastic piece by the windshield. I'm not sure if that is what's holding the windshield wipers in place though, so removing it probably wouldn't be a good idea for a DD.
