Supras and vents, a pairing as old as time. Like red wine and cheese, or grilled cheese and tomato soup, or if you're weird, Wendy's fries dipped in a frosty...
Our cars obviously come straight from the factory with....."vents" but as i'm sure all of you are aware, these "vents" do nothing other than get laughed at. NO MORE I SAY!
Allow me to introduce, the Rapid Designs A90 Supra Hood Vent
Born from the forges of my apartment at 11pm after numerous beers, crafted by the wise sages of Send Cut Send, and powder coated/packaged with love by myself, the Rapid Designs A90 Supra Hood Vent is not only functional but cost effective and pretty dang cool looking if I do say so myself.
Background
You might be asking, rwense, why design another hood vent when there are already a couple on the market? Well, unfortunately a number of my friends and myself purchased a hood vent from another manufacturer that has a tendency to warp at the first sign of heat. I won't name names but i'll refer to it as the "Warped Tour" vent.
This Warped Tour vent is larger than the likes of Verus and there were no other options on the market to replace it with/cover the hole it made. I reached out to a vent manufacturer to try and partner on a design to remedy the situation but that didn't get very far, thus I decided to fix it myself.
This version is revision 2 and has seen numerous track days and thousands of miles, not just on my own car but 15 other cars as I type this!
Benefits
Why would you want to put a massive hole in your hood besides me telling you to? There are 3 main reasons:
1. On track, the Supra suffers from IAT issues, even at stock power levels. Despite what people may tell you, basically the only way to solve this issue is to install an upgraded intake manifold (all the "upgraded" heat exchangers/radiators for the A90 besides those from PWR are comprised of aluminum and not the aluminum/copper matrix that comes in the factory parts). The only other option is to stave off power being pulled by way of venting....enter hood (and also fender) venting. With properly placed venting, the A90 can eek out a bit more time on track before power starts being pulled. Of course there are a variety of factors at play but the simple fact of allowing the heat exchanger more flow helps fight IATs
2. Along with IAT benefits, a properly placed hood vent can shift aero balance forward. I stress "properly" because a hood vent MUST be placed in an area of low pressure to properly function. Verus Engineering and the actual GT4's vent placement is ideal as it is directly behind the cooling stack and in the center of an area of low pressure. This ensures efficient flow not only maximizing IAT benefits but also aero benefits.
To be fully transparent, I have not done CFD nor will I claim xyz% improvement. Most aero manufacturers like to publish pretty CFD graphs without further testing (unlike Verus Engineering for example) thus the Rapid Designs vent was designed and relies on best practices.
3. It looks cool, and more importantlyyou'll get all the dudes/dudettes, and you're supporting a very small business (literally just me) 
. At the end of the day, I like making cool stuff for people and hearing their feedback. I'm always open to the community's input and hey, you're helping me pay for consumables 
Please feel free to pose any questions or give feedback!
What is included?
ā¢ The vent itself (5052 Aluminum at 2.5mm thick)
ā¢ 12Ć black aluminum rivets
ā¢ Cutting template
ā¢ installation guide PDF (hosted on my website)
