Designed to deliver an aggressive, hard-hitting exhaust note at idle, the Thumpr camshaft series from COMP Cams also delivers excellent horsepower gains and a broad torque curve. A perfect choice for muscle cars and street rods, the Thumpr series' early intake valve opening and long exhaust duration create optimum overlap for that race car idle. The Thumpr grinds all require an aftermarket torque converter and lower gear ratio to ensure the drivetrain always puts the engine in its powerband. Additionally, Thumpr camshafts typically deliver reduced vacuum at idle, making a vacuum canister, pump or hydroboost a requirement for vehicles running power brakes.

Electrifying
Format: Kindle
Talia Bhatt’s Trans/Rad/Fem is a powerful and thought-provoking collection of essays that delves deep into the intersection of radical feminism and trans liberation. This book challenges the idea that trans and radical feminism are at odds, instead arguing that transfeminism is a natural extension of radical feminist thought. Bhatt’s sharp, compelling writing makes the case that a materialist, radical transfeminism is key to dismantling the oppressive structures of patriarchy. What makes Trans/Rad/Fem such a captivating read is the way Bhatt blends academic analysis with personal narrative. Her essays are intellectually rigorous, yet accessible and relatable, striking a perfect balance between theory and lived experience. The electrifying prose has the profound impact of books like Stone Butch Blues. There’s something incredibly powerful in the way Bhatt’s words cut through, offering fresh perspectives on issues that often feel tangled or misunderstood. The essays feel like a conversation with someone who’s been thinking deeply about these subjects for a long time, offering not just insight but a vision for a different, more inclusive future. Some readers have noted that familiarity with radical feminist theory will enhance the experience, but even for newcomers, the book offers eye-opening and challenging ideas. Trans/Rad/Fem has clearly made a mark. Bhatt’s ability to engage readers while encouraging critical thought is part of what makes this collection so important. Whether you’re a seasoned feminist theorist or someone looking to understand more about the intersections of gender and social justice, this book is an essential read.

this is the book you’re looking for
Format: Paperback
I’d just finished reading Jules Gil-Peterson’s A Short History and felt a little unsatisfied and uncomfortable with all the orientialism. I picked this up and was immediately sure I had the antidote. Bhatt is clear, direct, and uncompromising. She avoids filler and gets right to the heart of things—“how is this not like blackface?” gets dealt with more thoroughly and decisively than I have ever seen it within the first few pages. She reveals the transmisogyny lurking in even nominally queer social and intellectual movements, and also finds pockets of beautiful solidarity and common ground in some surprising places. Above all, her love for women shines through every word. This book cleared up some misconceptions I had, made me cry, and will make me a better partner and comrade to trans women. Buy it.

Excellent essays in a brilliant book
Format: Paperback
This is a really excellent book. A lot of anthologies of essays have great essays in them, as this one does, but not all of them work as well as a cohesive text as Trans/ Rad/Fem does. I'd recommend this for anyone interested in transfeminism, even if you'd already read individual essays from Bhatt's newsletter by the same name. As with the essays in their newsletter format, The Third Sex and The Questions Has an Answer were my favorite. Bhatt's writing has such force and clarity that I look forward to reading whatever she chooses to write about next.
