If you have a stock engine, with a compressor that is factory set to produce no more than twenty pounds of boost, you shouldn’t modify the system to make it produce much more than 25 pounds of boost. And increase of 5 pounds over stock is probably the limit you should go by. Can a stock engine handle a turbo? Yes, but it’s usually a very bad idea.

Can you run a supercharged Chevy Silverado in town?
A supercharged Silverado is perfectly happy hauling to the limit or simply putzing around town. One important change when running a supercharger is that you will need to run premium gas all the time. Failure to do so will likely cause detonation.
What kind of engine does a Chevy Silverado have?
GM has now been equipping the Silverado pickup truck with LS based motors for nearly two decades. Starting with the Vortec series in 1999, Chevrolet has evolved their pushrod engine line-up to feature the generation V EcoTec3 small block series of today, which provide ever better horsepower, torque and fuel economy with each subsequent model.
How do superchargers work on Silverado pickup trucks?
Working on the principle as described above, superchargers are able to significantly boost the horsepower and torque output of that small-block found in any Silverado pickup truck. Furthermore, because the supercharger is connected directly to the crankshaft pulley via a belt, any time the engine is running, the supercharger is working.
How much power can a 5.3 handle stock?
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). If we apply 14.7 psi from our turbos to the stock 360hp motor, we might get 720 hp.
How much boost can you run on stock internals?
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.
How much boost can a stock LB7 make?
yes. 32 psi is the max on an LB7 turbo.
How much boost can a stock turbo handle?
Simply put, it can handle plenty of abuse (40 psi of boost and high drive). For an HX35 with a factory exhaust housing, we'd call it quits at the 400rwhp mark, as EGT can get pretty toasty at this point (1,500 degrees F).
How much hp can an LS1 handle?
Even in emissions-legal trim, a blown LS1 will pump out over 500 wheel horsepower, with 800 wheel hp available for a serious stroker effort. With turbo motors, the sky is the limit, as 1,000 hp is a common occurrence, with the ability to adjust the power output by turning a simple boost knob.
How much boost can a stock 325i handle?
BMW straight 6 iron block engine is capable up to 400 hp (up to 1 bar boost) on stock internals, you need to decompression it. You can do 0.55 bar boost on stock compression and it should do around 300 hp.
What size is the stock turbo on a LB7?
60mmStock Turbo, 1,200 HP! Along with the engine, the factory 60mm IHI turbocharger is still aboard Buddy's LB7.
How much power can a LB7 handle?
550 to 600 hpCouple that with a weaker connecting rod and you can draw a pretty strong conclusion as to why the LB7 rods fail in the 550 to 600 hp (1,100 to 1,200 lb-ft.) range. While we tend to talk in terms of horsepower, it's the torque of these engines that does all the damage.
Are LB7 fast?
Motor work it is a very fast truck the lb7 is the fastest motor of all the duramax motors.
How do you adjust the boost on a stock turbo?
0:007:38Adjust Your Boost Pressure - YouTubeYouTubeStart of suggested clipEnd of suggested clipAnd that's all there is to it there's no adjusting on it to be able to run higher than stock boostMoreAnd that's all there is to it there's no adjusting on it to be able to run higher than stock boost levels which is around 14 psi. You have to cam what's called a heavy-duty actuator.
How much boost can a stock lb7 turbo handle?
The stock turbo will go to 32psi safetly. Have heard of them going over that but wouldn't recommend it.
How much boost does a stock N20 make?
BMW N20 Max Boost Summary The small single turbo is able to boost up to roughly 24-26psi. Although, that's beginning to venture towards the upper limits of the engine and the turbo. As such, we recommend sticking to roughly 20-22psi as a safe limit for the stock turbo.
How much boost can a stock LB7 turbo handle?
The stock turbo will go to 32psi safetly. Have heard of them going over that but wouldn't recommend it.
How much HP can a stock LB7 turbo handle?
the stock LB7 turbo providing it with the right upgrades such as built tranns etc will get roughly 520 with 530RWHP max.. anything over that on a stock turbo will result in blown pistons due to the high EGTs but if you want to could spray another 50HP.
How many pounds of boost does a stock Duramax have?
The factory map sensor which electronically measures boost on a 2001-2004.5 trucks only reads to 22-24 psi, 2006-2016 MAP sensors read to 37 psi. If you want to read boost numbers higher you'll need an aftermarket gauge.
How much HP does a stock LB7 have?
Hypertech.com shows around 236 hp and 426 torque(IIRC) at the rear wheels. Those numbers are about as close as you will get without doing the dyno yourself...
What do you need to know about supercharging a Silverado?
What You Need to Know About Supercharging a Silverado. Written By: Connor MC. GM has now been equipping the Silverado pickup truck with LS based motors for nearly two decades.

What is a bypass system on a Silverado?
One other notable aspect to highlight is a bypass system. Some of the TVS-based Silverado supercharger systems are now coming with an integrated bypass system. This bypass circuit will prevent any positive pressure build-up when driving in a low load or high vacuum situation (light throttle cruising, engine at idle or throttle closed and truck decelerating), significantly reducing the parasitic draw of the supercharger when boost is not needed. A bypass circuit such as this is not to be confused or compared with a wastegate – the bypass system provides no boost control under load. The supercharger will always reach and maintain peak boost as needed. This is a nifty feature that helps bolster fuel economy without any sacrifice in performance.
What Makes Each Supercharger Kit Different?
Each manufacturer is responsible for coming up with their own proprietary intake and intercooler design, boost management, fuel requirements and engine tuning.
What are the factors that affect the performance of a supercharger?
Supercharger displacement, pulley ratio, fuel delivery and tuning capability are all important variables on the overall performance of the supercharger package, and each manufacturer likely has a different idea and setup of how to go about it. Think of it as a rib fest: everyone is cooking ribs, but they way they do it and the ingredients in use produce a unique flavor.
Does a Silverado need to run premium gas?
A supercharged Silverado is perfectly happy hauling to the limit or simply putzing around town. One important change when running a supercharger is that you will need to run premium gas all the time. Failure to do so will likely cause detonation.
Does the intake air heat up during compression?
However, during the compression phase, the intake air does heat up, which is not desirable. The solution to this is to send the air, after compression, to an intercooler where the inlet air can be cooled prior to reaching the intake manifold and entering the combustion chamber. What is really neat about the Roots-style supercharger kits available ...
Can I Install a Supercharger Myself?
Good news here. The answer is yes . Yes, you can install a roots-style supercharger on your half-ton Silverado at home in the garage. Surprisingly, despite all the bits and bobs that come with any Silverado supercharger system, no real specialty tools are needed. Just a complete set of sockets, wrenches, screwdrivers and a day or two of time is all that is needed to get the job done.
How much psi is a stock turbo?
intercooler isn't the problem....the stock turbo is....it isn't dependable above about 32 psi. If he wants to run that much boost, tell him to get a bigger turbo and possibly some headstuds.
What is the psi max on a stock tune?
I believe it is in the neighborhood of 23-24 psi max on a stock tune. It could vary as much as 18-24 from what I have read.
How much psi does a LMM turbo put out?
The turbo on a LMM might put out 40+ psi tuned with electronics, but it won't last very long. I read on another forum that a guy had the edge on his truck just for guages and tuned with another tuner. He thought he was safe until he put an actual boost guage on his truck.....it was boosting almost 50 psi on a stock turbo....with a VVT the vanes are computer controlled. He took the edge off and it went down to normal boost readings.
