Do you guys do these installations? I have a 2017 that I’m thinking on supercharging, I just want a street legal reliable truck, minor stage 1 or 2 cam swap & tune.
I thought the new 5.3 had 355 hp stock too. At least thats what mine is supposed to have. 305 is way below what theyre advertising if thats the case. Which is misleading.
Guys what they advertise is flywheel horsepower. The 308 is wheel horsepower, you have to account for the losses in the drive train. So there is about 13% loss from the flywheel of the engine to the contact patch of the tires. If they are putting down 414whp the engine should be putting out around 475 flywheel horsepower.
Wow really people, do you now know how a dyno works? It reads the HP at the wheels. 355 is at the crank. and you have about 13 percent drivetrain loss.
Hi Dan. You are right that the stock 2014 5.3L Silverado has 355/383 at the flywheel, but you have to subtract for drivetrain loss. Dynos measure at the rear wheels (or the front wheels for front wheel drive vehicles) after this drivetrain loss has taken its toll, and although vehicles vary with regard to loss, 15% is probably not very far off here. The numbers look right. I have a ProCharger supercharger (centrifugal, variable 0-8 lbs. of boost) on this very same setup that measures right at 440/490 on the dyno. I don't have ready access to the data sheets, as there were changes with tuning, but those are the rough numbers. I opted for a towing tune, as I tow a small fifth wheel and wanted to optimize low-end torque. Note that the ProCharger setup comes with a Diablo tuner. I don't use my 5500 lb truck to race (although it's fast!); it's simply a tool. If you take into account the loss that occurred, my flywheel hp is right at 500 and the torque figure would be somewhere in the 550-560 range. This is a somewhat educated guess, but it cannot be very far off. Of course, you have to take into account altitude and the consequential variance of oxygen levels, but at sea level these numbers look right. Unfortunately, my installer did not do a "before" pull, so I have no starting reference point, but the numbers are probably accurate.
How’s the truck handle the supercharge? Like drive train?

I hate when they don’t get back to you.
Wow people don't know the difference in Fly wheel and RW HP? MAGNUSON hurry up with the 6.2 2300
How much to install one of these to my 5.3 l silverado 2014 ?
Is this the 1.9L or the 2.3L?

Doesn't the 5.3 stock have 355 not 305...new ecotec
Wheel hp vs crank hp
So does that supercharged only put's out loke 60-70hp that blows haha see what i did their....
cortesefrain496 no
They are probably talking 305 at the wheel
Yeah that's clearly wrong.. I have the same truck it's 355hp and 383tq.
no its not. about 300 horsepower

Put e85 in for 380 flywheel hp
308 is what its putting down to the wheels its not wrong
Put e85 in for 380 flywheel hp
