What is the best stock bottom end for boost?
Combined with the smaller bore, the 5.3 apparently lends itself to being the best LS-ish stock bottom end for boost. I really like the fact that this setup would take only about $1500 (unless I'm forgetting something major).
What is the boost boost calculator used for?
This calculates the boost (psi) to achieve a nominated horsepower target based on your engines specifications and maximum rpm. Great when planning a new turbo kit or intercooler to see if it can achieve your goals.
What's the Best LS intake for my project?
We've established that the stock truck intake on the 5.3 LS is a good one and should do the job until nearly the 500 horsepower mark, but that doesn't mean it's going to fit your project. Taller than what one would find on a passenger car LS setup, you could run into hood clearance issues that will require swapping in something different.
How much power does a twin turbo short block engine produce?
Starting at just 5.5 psi, the twin turbo LM7 produced 696 hp and 606 lb-ft of torque. This increased to 930 hp and 806 lb-ft at 13 psi, and 1,014 hp and 872 lb-ft at 15.5 psi. The two-part question was a simple one. How much boost will a stock 5.3L short-block withstand before the proverbial Big Bang and what is the resulting power output?

How much boost can a stock LS take?
on a stock ls1/ls2. These boost numbers can be plenty safe so long as the car has the proper tune. that PSI *can* be safe detonation wise (with a really good tune!)...but common evidence suggests that 500-550rwhp is about the limit of stock internals, mainly the pistons and con rods begin to start dying over 550rwhp.

What is the fastest 5.3 engine?
Jon Capizzi, the mad scientist behind the world's fastest stock bottom end 5.3, is just that kind of special—or crazy, depending on who you ask. You may remember when his L33-powered Fox body Mustang shattered the SBE 5.3 record with a blistering 7.81 at 173.61.
How much boost can a stock 6.0 LS handle?
If you double this atmospheric pressure (by supplying boost from a turbo or blower), you can theoretically double the power output. On our 529hp 6.0L, this meant we could generate as much as 1,058 hp at 14.5 psi of boost, if everything went according to the formula (and the engine survived).
How much HP can a stock 5.3 block handle?
If we were to run the 5.3L in stock trim, the resulting power output would be around 360 hp (on this dyno, the way we test).

What LS is best for boost?
If you're planning on boosting your project the 4.8L truck engine will be perfect for you. The 4.8L can take insane amounts of boost completely stock and will really perform well.

What is the camshaft on a 5.3 LS?
Given that almost every 5.3 LS was installed under the hood of a truck, it's perhaps no surprise that their factory camshaft (191 degrees at 0.050-inch lift in the LM7) is designed to balance power and fuel economy and favor low-rpm torque. Gen IV engines moved to somewhat more aggressive cam profiles (196 degrees in the LY5, for example), but still oriented towards task-focused towing and daily driving above all else.
