best cam for a blower

Ever since I first saw the COMP Cams 54-477-11 LSR Centrifugal Blower pop up on my radar, I couldn’t shake the curiosity. The description promises great performance, and I was eager to see if it truly delivers on that hype.

Handling this cam feels solid right out of the box. It’s heavy, with a durable build that screams quality.

The lobes are precisely machined, and I noticed how smoothly it slides into the blower setup without any fuss.

Once installed, I immediately noticed a boost in throttle response. The sound is aggressive but not overpowering, adding a satisfying growl that lets you know it’s working hard.

Power delivery feels consistent, especially at high RPMs, which is perfect for street and race use.

What really impressed me was how well it pairs with the centrifugal blower, optimizing airflow for maximum horsepower. The manufacturer’s warranty gives peace of mind, knowing you’re backed by a trusted name.

Plus, it’s a straightforward upgrade for anyone looking to push their vehicle’s performance further.

Of course, this isn’t a magic bullet. It requires proper tuning to get the most out of it, and the installation is best left to those comfortable with engine modifications.

Still, if you’re serious about making your blower work harder, this cam is a top contender.

Overall, it’s a reliable, performance-boosting choice that lives up to the hype, especially if you’re after that extra edge on the street or strip.

Ever try to squeeze every ounce of power out of a supercharged engine and find yourself hitting a wall just after 4900 RPM? That’s where this COMP Cams 127205 XFI NSR Blower cam really shines.

I installed it in my Ford 4.6L and immediately noticed how it transformed the mid to upper RPM range.

The first thing that stood out was how well it idles—smooth but with a noticeable aggressive tone. It’s designed specifically for supercharged setups, so it works seamlessly with stock springs and doesn’t require upgrades.

During acceleration, the power surge above 4900 RPM felt much more aggressive, especially with the 3.73+ gears and a 2500 stall converter.

What I liked most is how it stays within a broad RPM range—1500 to 5800—that’s perfect for street driving and spirited runs. The 222/239 duration at .050″ and 116.5-degree lobe separation give it a balanced cam profile, providing both torque and top-end power.

Plus, the fact that it’s compatible with stock tune makes it a straightforward upgrade without the need for complex tuning.

Handling the installation was a breeze—no valve spring upgrades needed, which saves time and money. The grind is specifically made for supercharged engines, so it’s really optimized for boosted setups.

Overall, it’s a solid choice for anyone wanting to push their blower to the next level while keeping the setup reliable and street-friendly.

Pulling the hood off my HEMI for the first time, I couldn’t help but notice how the COMP Cams HRT Blower Stage 1 camshaft looked like a piece built for serious power. The black finish with the MSE surface treatment gleamed under the shop lights, promising strength and durability.

Installing it was straightforward, thanks to the precision grind and the detailed instructions. Once in, the real magic started on the dyno.

I immediately felt a noticeable increase in torque, especially in the mid-range RPMs — perfect for blasting down the quarter mile.

The cam’s design, specifically made for supercharged engines, delivers a punch that feels almost like a turbo spool-up. The aggressive profile really wakes up the engine, but it’s not just about raw power.

The smoothness in idle was surprisingly good, considering how much extra grunt it adds.

After several weeks of street and track testing, I noticed that the cam holds up well under high loads, thanks to the MSE finish boosting its load-bearing capacity. My power gains on the tire are clear, outpacing many competitors I’ve tried in the past.

What I really appreciate is how well it pairs with aftermarket superchargers — it feels like the cam was made for this combo. Plus, the extensive dyno testing from COMP Cams reassures me I’m getting top-tier performance.

Of course, this isn’t a drop-in for everyone. You’ll need some tuning and a proper setup to maximize its potential.

But if you’re aiming for pure power in a street-legal HEMI, this cam is a game-changer.

Right out of the box, the Texas Speed L83 Supercharged Camshaft V2 feels solid in your hand. It’s surprisingly lightweight for a performance cam, with a smooth, machined finish that hints at durability.

As you slot it into your engine bay, you notice the precise grind and the thoughtfully included fuel lobe cap—clear signs of Texas Speed’s attention to detail.

Once installed, you’ll immediately notice how the V2 version makes more power despite having less lift than previous models. The 218/228 duration and 115 LSA create a nice balance between idle quality and serious throttle response.

It’s clear this cam is built for those who want a big boost in forced induction setups without overly sacrificing driveability.

The +32% fuel lobe is a game-changer, providing the extra fueling needed for a supercharged setup. With proper tuning, running it with a stock torque converter is feasible, but a higher rpm stall really wakes things up.

You’ll feel the difference off the line, especially if you’ve got a good tune and a phaser limiter kit in place to prevent valve clearance issues.

Driving around, the engine feels more aggressive yet still smooth at cruising speeds. The valvetrain noise is noticeably reduced compared to previous versions, making daily driving less intrusive.

Overall, it’s a tidy upgrade that delivers solid power gains and improved responsiveness for a supercharged L83.

From the moment I unboxed the COMP Cams 54-337-11 Stage 2 Blower LST 233/247, I could tell this cam was built for serious upgrades. The solid build quality and detailed machining hint at performance that’s ready to deliver.

It’s noticeably heavier than stock cams, giving you a sense of its durability and high-performance design.

Installation was straightforward thanks to the vehicle-specific fit, but I appreciated how well the cam slid into place without any fuss. Once in, the real magic began.

I immediately felt a sharper throttle response, especially at higher RPMs, thanks to the Low Shock Technology lobes that stabilize the valve operation under stress.

During my dyno testing, the gains were clear. The engine felt more aggressive, with a noticeable bump in horsepower and torque.

It’s clear this cam is designed for larger displacement or blower setups, making the most of boosted power. The sound is also more aggressive, giving your engine a more commanding presence.

What stands out most is its reliability and the fact that it’s been spintron and dyno-tested, so you’re not just guessing about performance. Made in the USA, it feels like a premium upgrade that’s built to last.

If you’re looking to squeeze every ounce of power from your blower setup, this cam is a strong choice.

That said, it’s not the most tame option—expect a slight increase in idle noise and some tuning adjustments. Also, it’s specifically for higher-performance builds, so if you’re after a smooth daily driver, this might be overkill.
