Overview:
Hays Performance Drivetrain is proud to announce Twister 3/4 Race Performance Torque Converters. These NEW torque converters are a perfect addition to Hays product line of performance flexplates, clutches, and flywheels. The 3/4 Race torque converter is the first series being brought to market and is intended for street/strip combinations, with various RPM stall speed offerings to accommodate any mixture of modifications including higher compression ratios, aftermarket camshafts, aftermarket cylinder heads, lower gear ratios, and vehicle weight loss.
The name 3/4 Race perfectly describes a torque converter suited for an application just shy of a Full Race version. We do plan to offer Full Race torque converters in the near future.
Good names never go away, and neither should good terms!
Hays Twister 3/4 Race Torque Converters!
Features:
- 3/4 Race series converters are built, tested, and proven to support up to 650 HP
- State of the art Spray Welding process is used in select areas. Spray Welding provides clean, strong and consistent fusion while also increasing strength through hardening from higher process temperature
- Each converter is hand-built and inspected in every step of assembly to ensure top of the line quality
- All HAYS converters are internally welded compared to brazing. Testing has shown welding provides longer converter life while also enhancing consistency
- Heavy duty Torrington bearings are used for greater strength and durability
- Stators are chosen with high flow vents and channels to promote cooling in heat producing higher horsepower applications
- Increased horsepower and acceleration due to a weight saving, one application design. Almost all HAYS converters are built for one application to reduce weight compared to a multi-bolt pattern converter.
- 3/4 Race series converters are offered in several different stall speeds for GM, Ford, and Chrysler transmissions
- Industry leading Tech Support Team is available to provide assistance with stall speed selection

Wonderful
Format: Kindle
What a wonderful long read, with depth, emotions, storyline and a touch of $mut. This story was definitely more centered around the storyline rather than any $ex scenes and lived up to “Cozy Omegaverse”. We saw the pack dynamic’s evolve as she was ready for them to evolve, they were patient with her and allowed her to break free from her own constraints.
Amazing!

A Nice Story
Format: Kindle
I love Omegaverse and its many stories. The book is a wonderful story. The characters are intriguing and are each unique. There were a few issues with repetitive phrases through out the book and a few misspellings but the biggest issue was the very painful slow burn. I feel if it weren’t so slow
It could have incorporated more content about each character. Overall a solid story though.

decent…but
Format: Kindle
This is my first book from this author, and while I do really love omegaverse stories, this one left a lot to be desired. This book is a hard-core slow, slow, slow burn: (75% or later in the book)
I will say that I finished it. Unfortunately, I struggled through a lot of it due to punctuation errors, and general editing that must have been looked over during the revision process.
I also feel like a lot of information was left out and there wasn’t closure regarding her parents. The dynamic of the pack before Lydia joined is a little confusing, the only person who showed affection towards Elias was the Head alpha. The other two seemed indifferent to him in an intimate relationship way. That doesn’t really scream cohesive pack to me.
I am hopeful that the next book in the series is better edited, and that the author decides not to use the same phrases over and over again. I’m pretty sure “honey-warm” was mentioned over 15 times when describing Elias’s scent. That got really old, really fast.
Overall, it was a decent book. Not sure I would read it again or recommend it until of these errors are remedied.

Definitely a comfort read
Format: Kindle
Just a comfy cozy nice long read. While this is definitely a SLOOOOOOOOWWWWW burn, this is how you do RH right; a nice long novel where you actually get to know the characters so you can feel more connected to them & the story, not to mention getting enough time to actually remember all their names haha. & they are all consent kings. Also I do so love me some double omega OV, siiiigh (heart eyes). I wish there had been juuust a bit more spice, like maybe just between Elias & others before MC was ready (made Elias feel a bit underdone or gimmicky without it), I did love this read. Low stress, comfy read. It could've used another round of editing for some minor errors & type issues but it wasn't bad enough to pull ne out of the story. Though I did giggle at 'knecks', thinking kuh-necks in my head. Overall I'd say 9/10

beautiful story
Format: Kindle
I absolutely love this book, however there is quite a bit repetition! The storyline makes up for it, a just skipped them. I like that this was a cozy read, it’s an omegaverse romance, but really barely read as OV, you get a little hierarchy and scent blockers, but if not for that you wouldn’t know. I love the romance aspect however, they take there time and move at her pace! A good read, with some errors, hopefully there is more to come!!
