This is our different BigPack configurations for the BMW M2 / M3 / M4 F8X. These are complete packages for the charge air cooling system with drop-in-fitment!The S55 turbo engine that powers the BMW M2C / M3 / M4 F8X uses a Top mounted water-cooled intercooler instead of an regular; air-cooled intercooler. The stock top mounted intercooler has a Tube&Fin core with clamped plastic end tanks. This construction has its drawbacks since it is prone to crack and start leaking coolant into engine or leaking boost pressure out of the tank sealings.
The coolant in this system has its own separate cooling circuit combined of two parallel connected radiators and a pump. The larger one of these two parallel connected radiators is positioned in the front of the center cooling pack, the second smaller one is located in front of the right-side wheel arch.
These cars are equipped with plastic intercooler pipes on both the hot and cold side. These pipes are a week link on any tuned car or in some cases even on a stock tune. The OE plastic pipes often crack / split leaving you with a boost leak.
We have designed upgrades for all these parts by advanced 3D scanning and 3D modeling in the scanned environment. We conducted CFD simulations on most parts and several tests to make sure we deliver the best performance upgrade!
You can choose between three different options for this product.
1. Intercooler and both intercooler pipe kits
2. Intercooler and both radiators for intercooler system
3. Intercooler, both intercooler pipes and both radiators for intercooler system
Our performance intercooler helps your engine to make more power both by lowering the intake air temperature and lowering the pressure drop! It is a bar and plate unit with 3D freeform designed end tanks TIG welded to the core. It has a core volume 85% larger than stock intercooler and outperforms the stock unit both when it comes to air flow and cooling efficiency. 16% better flow and 9°C lower IAT, so with both better flow and lower IAT this is a true upgrade!
Our radiators for the charge air cooling circuit lowers the water temperature in the charge air cooling system circuit. This is equal to lower intake air temperature which gives both more power and a more persistent performance. We achieve this by increased cooling face area, increased core thickness and well composed cores made with multichannel tubes!
Our intercooler piping, both the ones that goes from the turbochargers to the intercooler and the one that goes from intercooler to throttle body is designed to add durability and at the same time improve air flow. It is not easy to improve both reliability and improve air flow as the stock pipes flows well. With our software flow simulation and physical flow verification abilities we are sure that we are making improvements which is more than most suppliers of this kind of pipes can say!

Best academy I've read this year
Format: Kindle
I need a few things when it comes to a first book of a PNR romance series
1-Good world building (which this totally did)
2-An FMC I can root for (oh hell yes, Pandora is someone I can cheer for)
3-Good drama (can you say GROVEL BOYS!)
4-Enough story to make you feel like you really read something with meat (you saw this book is like 600 pages, yeah?)
5-A hook at the end so I want more! (please, Lyra, gimmie more?!? I need more!!)
Be aware this book is a slow burn, but damn do I feel like there'll be some big payoff when it finally happens. Who doesn't like the buildup?

Pandora’s Pain, Power, and Passion
Format: Kindle
I absolutely love this new world Lyra Winters has created! The spin on a Demon Academy setting was fresh, unique, and completely addictive.
Pandora is a character who immediately captured my heart. Thought to be powerless and enduring years of brutal abuse from her mother, it’s no surprise that her powers emerge at the exact moment she needs them most. After her mother’s death, Pandora discovers her father is none other than Death himself, a soul eater with a dark legacy. Her journey at the academy is anything but easy, filled with challenges tied to her father’s infamous reputation, her barely controlled abilities, and the cruelty of those around her.
Pandora is easy to root for, you feel every ounce of her pain, resilience, and growth. Along the way she meets Reed, a half-human dream demon who’s kind, steady, and the kind of friend everyone wishes they had. There’s also Hunter, a vengeance demon and counselor connected to her father, who adds another intriguing layer to her story. Then there are the bullies: Dexter, a brooding shadow demon; Bram, a chaos demon with a drinking problem and deep hatred for demon nobility; and Skel, a fear demon wrestling with his own darkness. They might hurt her, but they also can’t seem to stay away when she’s in danger, making for some deliciously complicated dynamics.
This book hits so many of my favorite tropes: friends to lovers, enemies to lovers, and of course, the irresistible “who hurt you?” storyline. I devoured it, and I’m already diving straight into book two!

So good!
Format: Kindle
Oh my goodness! What did I just read? Lyra Winters you have some serious explaining to do! That cliffhanger killed me! I am so happy to be back in the world of Kalista. This is definitely darker than Fates Hollow but oh so good. This is a fated mates reverse harem which I absolutely love.
Pandora had a very hard and rough upbringing. She lives in pain constantly and it makes it hard on her. She struggles with everything because she was kept so isolated and is new to her magic. Pandora gets sent to the Reform Academy and all of them have reasons why they are there. I love how, after everything she has been through, she is still a nice person. She is growing and becoming stronger too. Love her character.
The guys all act like jerks at first but all have a back story that helps understand why even though want to smack them. I'm here for the groveling that I'm sure will come. I love them all. They each bring something for her. They are all drawn to her though.
This is a slow burn book but there will be more books in the series so sure it will build. Man, that cliffhanger was a doozy and need book 2 now!

Good-ish
Format: Kindle
🌶️ 0/5
⭐️ 3/5
I will preface this by saying I am not a huge RH fan. However it didn’t feel like a RH quite yet. The relationships and plot are all building in this book. At first I was thinking things were happening stupid fast since she’s had zero interaction with another being and has been tortured her whole life, and I believe they were for one side of the relationship, but by 50% things moved too slow lol. Idk I think the main 1-3 guys I’m actually interested in more than the others didn’t get enough air time so I hope the next book things start moving with them since it ended the way it did.

Can I have Term 2 now?
Format: Kindle
This is by far my favorite book of Lyra's to date. I gobbled this book up so fast, I was so upset I finished it. I know this is going to be a book I reread, just like Fate Hollow Academy.
I loved Fate Hollow Academy, so I was excited when Lyra announced she was taking us readers back to Kalista. Although the characters from Fate Hollow are mentioned several times throughout the book, this book is about Pandora and her love interests in the Demon Realm.
Before you deep dive into this book, definitely look at the trigger warnings before you start. When Lyra says there's dark themes in this book, she meant it. Also, just know this book does end on a cliffhanger and will probably leave you with as many questions as it did me.
Below may contain some minor spoilers, so keep that in mind if you want to keep reading my review.
Pandora's first 2 decades of her life are full of torture, hatred, and confinement in a cellar. That is until her father finds her and brings her into the world she was supposed to live in. Because of her upbringing she wasn't acclimated to the Demon world and the way their society works so when she is offered the chance to go to a Demon Reform Accademy, she accepts it to learn the ways of society and how she is supposed to feed.
Pandora isn't like the other common demons in this world, no. She, like her father Death, are soul-eaters. Pandora is too scared to release her powers because she doesn't want to kill anyone, so she needs to learn how to feed off of a piece of soul instead of taking the whole thing.
Because of who her father is, she's classed as a Noble, and while she doesn't agree with her fellow Noble students, who look down on the "lower" class, she also is faced with 3 Demons who hate her for being a Noble. Theses a lot of back and forth tension which these 3 demons who have issues of their own. One is obsessed with her, and wants to know all of her secrets. One leaks fear all over the place, but also is scared of the "princess" -wink- -wink-. One is a complete drunk who doesn't like her just because he's got family Noble problems.
Don't worry, there are 2 other demons who are just the sweetest towards her. One who will get vengeance for anything done to her, he's got Golden Retriever energy around her and touch her and die energy for anyone around her. Finally, there is one who is friends with her even when the whole school is scared of her, who brings her into his dreams and will create nightmares for those who bother her.
