The LS9 uses a bigger 2.3L supercharger (LSA 1.9L), which allows for more boost. This means the LS9 requires stronger internals, making it safer at higher outputs than the LSA.
Are LSA and LS9 heads the same?
Heads for the LS9 used titanium intake valves like the LS7. The main difference between an LSA and an LS9 head is the valves as well—the LSA heads used a stronger rotocast A356-T6 alloy.
How much HP does an LS9 make?
638 horsepower
The LS9 is a supercharged 6.2L that produces 638 horsepower and 604 lb-ft of torque. It features high-rpm-validated lightweight reciprocating parts, titanium intake valves, forged internals and high-flow cylinder heads that draw the charge forced on them by a sixth-generation supercharger.
How much HP does LSA add?
The LSA has a very small camshaft. Upgrading to a LS9 camshaft is worth about 30 hp, however, it won’t make more power until 4,800 rpm. It’s really only worth it if you plan on running at high rpm. Larger, aftermarket cams can add about 50 hp.
Is the LS9 a good engine?
When the supercharged LS9 debuted, it was the most powerful production engine ever offered by General Motors. It was the standard engine in the C6 Corvette ZR1, helping it to achieve enviable performance benchmarks. The engine was praised for its civility at low speeds, and remarkable tractability at all speeds.
How much HP can an LS9 handle?
(The LS9 came with forged pistons from the factory.) Due to extremely high cylinder pressure, the heads can start to lift around 1,000 hp.
Which LS engine is best?
LS7: Best.
LS Engine. Ever. In a world with 650hp Camaro ZL1s, along with even more powerful Hellcats and Shelby Mustangs, it’s easy to forget the influence and importance of the LS7-powered Corvette Z06. Before it, there were precious few production cars that boasted horsepower levels of 500 or greater.
What replaced the LS9?

What is the highest HP LS engine?
The LS engine with the most power is the LS9 from the C6 Corvette ZR1. It is factory supercharged and makes 638hp. The newer Z06 and ZR1 make more power, but they are no longer referred to as “LS” engines, they are “LT” engines.
How much boost does a LS9 make?
On the 6.2-liter LS9, the blower generates about 10.5 psi of boost, but only about half that with the 7.0-liter LS7, so Thomson uses a higher-flowing “snout” and smaller-diameter drive pulley from Lingenfelter Performance Engineering to help spin the blower faster, bringing the boost up to about 16 psi.
Which is better LSA or LT4?
The new LT4 engine vs the old LSA engine
That’s quite the difference. Also, near idle speed (around 1000 rpms), the new LT4 engine makes approximately 440 lb-ft while the old one made a “measly” 375 lb-ft. So in English this means we have a lot more torque, which means much quicker acceleration.
Can you put an LS9 supercharger on LSA?
Lingenfelter Performance Engineering (LPE) has created a new supercharger conversion front cover that an upgrade to the LS9’s TVS2300 supercharger on TVS1900-equipped LSA engines without having to change accessory drives or throttle locations.
Which LS motor is the fastest?

What is the difference between LS9 and LT4?
Inside the LS9’s bottom end, the crank, rods and pistons are all forged, while the LT4 swaps the forged titanium rods for modern machined steel units. The LT4 cylinder heads also flow better than the LS9’s, and while the valve angles are the same for both engines, the LT4 has slightly more exhaust lift.
What LS is best for turbo?
“All of the engines are great with a turbo, but the 5.3 and 6.0-liter engines are the most popular. The 5.3 is the cheapest and easiest to find, so you’ll see a lot of people use it. With a 5.3 and 6.0, you can see up to 1,000 horsepower on a stock motor if you push them.
What LS block is the strongest?
BMP claims its cast-aluminum (357-T6) LS block is, “the absolute strongest available with important improvements that even the factory race blocks don’t have.” The oiling system is priority-main, meaning that oil gets fed to the crank first and the top end last to prevent starving the main bearings of oil.
