Forge Motorsport has long been associated with clever, ground breaking innovations, but the companys latest design is one of the smartest ideas to appear onto the automotive aftermarket for quite some time; the Intake Pressure Compensation Valve (IPCV) an idea so ingenious that we have patented it!
Dump valves, Blow-off valves, call them what you will, but hopefully, were all reasonably familiar with the concept these components are a safe way of allowing excess boost to escape harmlessly when off-throttle, and holding the boost system tightly in check when mashing it into the carpet. Excess boost vents either to the atmosphere, with its familiar metallic sneeze, or for those that prefer their journey to sound a little more subtle, back to the low pressure side of the turbo circuit, depending on the type of valve you run.On cars with low or factory boost pressures, the spring or diaphragm inside these valves only has to be a fairly weak affair. This allows the valve to move quickly and freely, but with the downside that the valve is useless on a tuned or high-boost car. That lack of resistance simply wont be able to keep the valve gas-tight as the boost pressure increases.
For tuners, the solution to that problem has been simple for many years now, simply up the spring rate inside the valve (diaphragms tend not be up to the job on tuned vehicles) to allow it to cope with the higher internal pressures created by the tuning process. This keeps the valve shut under load, but with the downside that response time is reduced thanks to the spring being stiffer, and therefore physically harder to compress.The fitment of the stronger spring can also limit the opening of the valve which restricts the volume of air it can flow. For this reason, most quality valves come with either a choice of springs or some kind of internal pre-load adjustment, in order to allow the tuner or owner to set the internal spring pressure to match their boost settings.
But this brings us onto to our next problem. Thanks to the plethora of sophisticated ECU software out there, these days, many cars also have some kind of easily-switchable throttle maps. On systems like EcuTek, where moving between throttle and boost maps can be as simple as clicking and flicking your cruise control switch, how on earth can a dump valve spring be perfectly set for your everyday 1.0 bar map, but also work perfectly for your drag strip all-out 1.4 bar mental mapping? Put simply, it cant so up until now, all dump valves had to be set to some sort of compromise to be a jack of all trades, and master of none.
If only there was a way to make the dump valves spring operation completely independent of the spring pressure inside. A way to allow its function to work perfectly at any boost level. Clearly concerned by this very same problem, Forges technicians beavered away to find a solution. What they came up with is called the Intake Pressure Compensation Valve (or IPCV for short) and its really rather clever.
What makes the IPCV valve ingenious is that it re-routes the various high and low pressure feeds through a clever internal piston system (see diagram). When the throttle is opened and the car is accelerating, boost pressure generated by the turbocharger will ensure that whichever dump valve or recirculation valve you have fitted will be kept sealed. As no boost is now being lost through the intercooler (which can usually be anywhere between 1-3 psi of boost drop) the pressure acting on top of the piston of your dump valve is precisely equal to that underneath it. The result? Only a relatively weak spring is required to keep it operating, which means response times can be kept quick and throttle response is immediate.
As dump valve springs usually have to compensate for the pressure drop across the intercooler, and this problem is now no longer an issue, the dump valve can now be run with a very weak spring. In fact, during testing, Forge Motorsport has actually been able to make this system work with no spring in the dump valve at all!
When the throttle is snapped shut either to change gear, or on over-run, the vacuum created by the engine opens up the dump valve and allows the air to either recirculate back around the turbo (in the case of a recirculation valve) or straight back out to the atmosphere. Put simply, what these means, is that even on a fire-breathing 1200 bhp GT-R, the dump valves now only require a very weak spring to operate perfectly with no boost loss, allowing them to open more responsively on partial throttle, improving performance in every gear, and at whatever revs you care to use. Best of all, this principle works as well on a bone-stock Subaru WRX as it does on a Drag-spec Evo. Boost levels simply dont affect this part of the equation any more.
So if you want to know that your valve is always perfectly matched to your engine at all times without any spring changing or adjustment - just fit the Forge IPCV.

I've tried MANY sunscreens. This is the best for the money you can buy.
Style: 4 Fl Oz (Pack of 1)
I have a section in my closet reserved for the graves of past sunscreens. And there are A LOT. Reasons why this is the best for price point:
1. No white cast. Maybe 2%. Yes, there is a bad a white cast when you first put it on, especially if your face is still a tad damp from washing. But it almost completely disappears within minutes. And this is coming from someone who is of Southeast Asian descent, and currently have a natural a tan this time of year. I get tan because I don't apply it every 2 hours as recommended. I only use it when I'm working out outside and the sun is blasting my face. I live where it gets very sunny.
2. NOT oily. I have super oily skin and so many of my sunscreens makes my face more of an oil slick than normal. I have matiffying ones, that work well, but it gets expensive.
3. Fragrance free! I prefer to use as many fragrance-free products as possible.
4. DOESN'T STING EYES. I'm surprised at how many "sunscreens for the face" are out there that absolutely sting my eyes into waterworks.
5. Price-point. A giant tube (for the face) for all that? It will take me a very long time to go through it. For my body, I use cheaper fragrance-free mineral sunscreens, or sunscreens I want to get rid of.
6. I use a moderate strength prescription of Tretinoin, and those who know, know that without sun protection, the skin can get burned and irritated extremely easily. Not me! And I use Tretinoin every single night.
I'm so glad Eucerin made this, I hope they never discontinue this!

Awful for normal/combo skin types!
Style: 4 Fl Oz (Pack of 1)
Terrible for normal/combo skin! I applied sunscreen to my clean, dry face – without moisturizer. After waiting 25 minutes, I checked to see if the product hadn’t absorbed into my skin. It remained on top of my skin in a shiny, slippery, greasy film that rubbed off onto anything it touched. It’s settled thickly into crevices and fine lines, especially in the folds of my eyelids. There was so much shine – not glow – on my skin that it created flashback when I took a picture. Somehow, the sunscreen made my skin appear both oily and dry at the same time! Many other reviewers said that they successfully put make up over this sunscreen, but I cannot imagine how this would be successful, unless the makeup finish was incredibly matte. It’s the worst experience I’ve ever had with any sunscreen!

My Family's Favorite Sunscreen!
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
This is our go-to sunscreen and my family has not used any other brand since discovering it about 5 or 6 years ago. The scent is pleasant, light, and tropical. Application is quick and easy. It goes on clear (not white) and looks a little greasy at first, but that is actually a positive because it helps you quickly see spots you (or your child) missed. It soon absorbs cleanly and the oily feeling goes away after a few minutes. The sunscreen works really well. My family has very pale, sensitive skin with eczema and easily burns in the sun. It does not irritate our skin at all and provides great coverage. This stuff works very well for us on vacation in Florida and on Bahamas/Caribbean cruises. It fits easily in a small bag and doesn't take up much room. With it being a solid, there's no worry of leaking. I love that you can hand everyone a stick and they can do most of the application themselves. Then we turn around and get the hard to reach spots on each other. And all done with clean hands that aren't getting messy. I would be so sad if this sunscreen is ever discontinued. We have over a dozen sticks in our house/car/luggage at any given time.

No Fuss For Kids
Style: Sunscreen Stick, Size: 1.5 Ounce (Pack of 1)
Neutrogena Sunscreen Stick SPF 50 – A Summer Must-Have!
I absolutely love the Neutrogena Sunscreen Stick SPF 50 — it’s a staple in our summer routine. I always keep several on hand: one in the car, one in the stroller, and one in our beach bag. It’s just so convenient to have wherever we go!
What makes this sunscreen stick stand out is how easy it is to apply, especially on my kids’ faces. There’s no mess, no fuss, and no need to rub it in. I can quickly swipe it on even when they’re squirming or in the middle of playing. It goes on clear, feels lightweight, and doesn't leave a sticky or greasy residue.
This product gives me peace of mind knowing my kids are protected with broad-spectrum SPF 50, and I don’t have to wrestle them into a full sunscreen routine. Total win for busy parents!
Highly recommend for anyone looking for a quick, reliable, and kid-friendly sunscreen solution.
