best cam for lsa supercharger

The moment I installed the BTR Brian Tooley Racing PDS Stage 2 Torque Camshaft, I was surprised to find how much smoother the engine felt at idle. It’s not often you get a cam that boosts power and still keeps things tame enough for daily driving.

My initial assumption was that a bigger grind would mean rougher idling, but BTR’s new lobes are a game changer.

What really caught my attention was how much more torque I felt across the entire RPM range. Pulls are noticeably stronger, especially in the mid-range where most street fun happens.

The sound? Deep, aggressive, but refined—a perfect balance for street setups with superchargers.

The build quality is impressive. The kit includes everything you need: the cam, dual springs with titanium retainers, valve seals, and chromoly pushrods.

It’s clear this was designed with durability in mind, tested on Spintron and dyno before it ever hit your engine. Even with less intake duration, the power gains are significant, proving BTR’s engineering prowess.

Installing the kit was straightforward, thanks to detailed instructions. The combo with the BTR springs and pushrods means you’re not just swapping a cam—you’re upgrading the entire valvetrain.

If you’re running a supercharged LS, especially with an LSA or Magnuson setup, this cam really unlocks the extra potential.

Overall, this cam exceeds expectations in both power and drivability, making your supercharged engine feel more alive. It’s a smart upgrade for anyone looking for serious torque with a reliable, tested package.

Fitting this Texas Speed TSP Stage 4 F-35 LS3 LS A Camshaft into an LS engine is like switching from a smooth cruiser to a full-on race car overnight. The first thing you notice is its aggressive grind, with a 235/248 duration and .649/.615 lift that really wakes up the top end.

It’s designed specifically for high RPM power, so if you’re chasing that adrenaline rush, this cam hits the mark.

When you drop it in, the idle immediately takes on a more conspicuous, performance-oriented tone. It’s louder, raspier, and unmistakably aggressive.

But what really stands out is how broad the high-RPM power band feels—like it’s made for racing or serious street performance. You’ll notice a significant jump in airflow and horsepower, especially if paired with supporting upgrades like a supercharger.

Driving with this cam feels like unleashing a beast. The throttle response is sharp, and the power delivery at high RPMs is downright thrilling.

It’s built for those who want maximum output and are willing to tune their setup accordingly. Keep in mind, this isn’t about smooth cruising; it’s about raw, unfiltered performance.

If you’re ready to push your LS3 to its limits, this cam will do just that.

However, it’s not plug-and-play. You’ll need supporting valvetrain parts and a proper tune to get the most out of it.

Also, expect a somewhat rougher idle and more noise, which is typical for a high-performance cam like this. But if you’re after a cam that delivers serious top-end power and an aggressive character, this one from Texas Speed is hard to beat.

Imagine finally cracking open your engine bay and feeling that familiar frustration—your camshaft just isn’t pulling the power you know it’s capable of. You want more torque, more punch, especially with your supercharged LS engine, but most cams feel like they’re just not optimized for boosted setups.

That’s where the BTR PDS Stage 2 Torque Camshaft really shines. From the moment I installed it, I noticed how smoothly it integrated with my LSA supercharger.

The cam’s 221/224 duration and .619/.617 lift hit that sweet spot, giving me a noticeable boost across the entire power curve.

What impressed me most was how it managed to deliver more torque without sacrificing idle quality or drivability. The new lobes, tested extensively with Spintron and engine dynos, strike a perfect balance—power everywhere, yet stable and durable.

It’s clear BTR engineers went back to the drawing board, and it shows.

Once installed, I immediately felt the difference during acceleration. The engine revs more freely, and the throttle response feels sharper.

It’s a significant upgrade over stock, especially if you’re running a Magnuson, Whipple, or LSA supercharger. Plus, it’s compatible with a range of LS engines—making it versatile for many setups.

Overall, this cam is a game-changer for anyone wanting maximum torque and power in a supercharged LS application. It’s a high-quality piece that delivers on performance and reliability, making it well worth the investment.

Right out of the box, the Texas Speed LS3 Stage 3 Camshaft feels like it was built for serious power. The 231/246 duration and .640/.615 lift immediately tell you this isn’t a mild upgrade—it’s designed for those who want to push their LS3 or LS2 engine to new heights.

Handling it in your hand, you’ll notice the solid construction and precise machining. The 3-bolt design ensures a secure fit, and the included spring set makes installation straightforward if you’re upgrading your existing setup.

When installed, the aggressive cam profile really wakes up your engine’s top-end power, especially with a supercharger in place.

During testing, I found that the cam’s 111 LSA gives a nice balance of idle quality and high-RPM performance. It’s clear that Texas Speed developed this cam on their dyno, optimizing for maximum gains.

The recommended stall speed of 3,200 RPM in auto setups means you’ll feel the difference right away, with a noticeable boost in throttle response and overall power.

In real-world driving, this cam delivers a snarling, aggressive sound that turns heads. It’s perfect if you’re after more than just a slight upgrade—this is for enthusiasts who want their LS3 to roar on the streets or strip.

Just be prepared for some tuning to get the most out of it, and a bit more noise at idle.

Overall, if you’re running a supercharged setup and want a cam that maximizes top-end power without sacrificing too much daily drivability, this is a solid choice. It’s a well-tested, high-performance camshaft that truly makes an impact.

I’ve had this BTR Stage 4 Supercharged Camshaft V2 on my wishlist for a while, mainly because I wanted to squeeze every ounce of power out of my LS engine with my Magnuson 2650 supercharger. When I finally installed it, I was blown away by how aggressive this cam truly is.

The first thing you notice is the ultra-aggressive idle—it’s loud, raspy, and unmistakably powerful. The lobes are ultra-stable, so even at high RPMs, you feel a solid, responsive performance.

I paired it with a 4″ stroker kit, and the gains in torque and horsepower were immediate and noticeable. Acceleration feels more brutal, and the engine sounds like it’s roaring with purpose.

Installation was straightforward, thanks to the 3-bolt pattern and compatibility with 1999-2015 LS-based engines. The specs, like the 229/25x lift and 116 LSA, translate into a wild, high-rpm beast that’s perfect for max-effort setups.

I’ve run it through both street and track, and it holds up well without sacrificing too much driveability—though, beware, this isn’t a cam for the faint-hearted or daily drivers.

Overall, this cam really lives up to its reputation as the most aggressive offering from BTR. It’s a beast designed for those who want serious power and are prepared for a louder, more aggressive engine tone.
