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.

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know. PRO: * Very likable characters * Lots of steamy scenes that are written very well * The spelling and grammar are good * The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens. CON: * Almost no interactions with any characters outside of Madison and the pack * Nearly no plot. They meet, get together for a heat, agree to make it permanent, done * Quite a few typos such as extraneous words, missing words and words out of order THINGS TO KNOW: * More steamy scenes than storytelling * A lot of MM & MMM, some MFMM during heat

Fluffy and Nice Omegaverse
Format: Kindle
… this would have made 5 stars but for 2 reasons. A.) there were quite a few typos; misspelled words, missing quotations, “the his” mistakes, and various signs that maybe a proofread would do good. B.) the writing was quite textbook. Late blooming omega is struggling with her new self, finds a absurdly wealthy pack of alphas, every thing is almost insta-love but she resists, then decides to love herself and let everyone be happy. Rian was my favourite (obviously the author’s favourite too because he got the most page time) but I wish we could see more of his CEO side? He went to work maybe ONCE the entire time. Gray was supposed to be the “growly one” but he turned out to be puppy dog. Lucas was a genius brainiac doctor - but also super alpha with an aggressive hindbrain with a breeding k*nk?? And then there was no actual “breeding”?? Spice 3/5 - normally omegaverse books are super high on messy smut but this was tamer. Romance 3/5 - insta-love that was then resisted because of personal hangup’s Plot 2/5 - weird paced head hopping, showing the same scene from different POV’s that made me feel like it was 2 steps backward, 1 step forward. Humour 4/5 - there were a dozen lines that genuinely made me chuckle out loud Would have been five stars but the lack of proofreading and the predictable plot made me unable to get up to ADORED IT level - four stars is still and official ENJOYED IT, y’all. This isn’t a bad rating. The “Club Heat” has intriguing possibilities so I’m going to give the second one a shot.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book. Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray. I wish it had been proofread - there are a lot of typos, but nothing too distracting.
