It’s weird to me that more people aren’t supercharging these new 10 speed gmc/chevy trucks. I’ve yet to see a video of one in the 700hp plus range. Meanwhile there’s plenty of 700 plus whipple f150s.
Because the GM motors don’t handle boost well. The rings are gapped extremely tight so they have to be really conservative on the tune and boost or the rings will touch and break a piston ringland and wipe a cylinder out. I have a fully built forged and stroked 416 Lt1 for my 2018 Camaro SS because the rings touched and fragged my stock motor. My 23 f150 has a stage 2 Whipple and makes 600whp easily and safely. Whipple claims the kit makes 775 crank hp but it usually dynos out at 600whp. And it will easily take more with proper fueling and a tune. That’s why I bought my f150 instead of a new GMC, Cheap, and reliable HP!
Cam only actually. It’s a 5th gen LT1 so it’s direct injection instead of port injection. The cam drives the mechanical high pressure fuel pump on these so a larger cam with a larger fuel pump lobe is needed to supply more fuel. It’s pretty much the limiting factor on these engines which is kinda why I don’t like them as much as an LS.
I mean for bone stock that’s pretty good wheel HP. It was probably making 315 wheel before. So blower only 115 plus hp. Pretty good gain. And the blower is probably only putting out like 6-7 pounds of boost max. Everybody expects 600 plus horse but you’d need cam heads bolts on and a good 93 with a smaller pulley to do that.
This was a 4.5” pulley good for about 5 psi of boost. It’s pretty much fuel limited at this point since the high pressure fuel pump is cam driven and the stock cam lobe just can’t supply enough to keep it safe with the timing.
5.3 truck I assume? It’s not bad for the relatively low boost. It will make that 5.3 run with a full bolt on 6.2 truck all day long, so it’s definitely a solid gain over stock.
crank horse power is measuring from the balls, it always sounds better in the sales brochure. as far as actual WHP expect a 20-30% drop from crankshaft to wheels. factor in auto trans/ manual/ rwd/awd. hell even running different compound tires will effect a Dyno graph.
So a 6.2 makes 420 horse and 460 stock. How does it only make 15 horse power more and and 53 ft lbs less with a super charger? Something ain't right at all. And if it is right, that was a complete waste of money
So those are numbers given to you by Chevrolet which are best numbers they made on an engine dyno at the flywheel. Otherwise known as crank horsepower/torque. On an automatic drivetrain, you will lose 18-25% of that to drivetrain loss through the converter, transmission, driveshaft, differential, axels, and wheels. In this instance, with this vehicle being so new, our tuner could not for the tuning program to make the TCM lock it in gear for a 1:1 gear ratio to the tires from the crank to the dyno roller and the vehicle always wanted to shift out if you went to wide open throttle, so he had to roll it into gear with progressive throttle. this makes the numbers seem low but it’s actually much higher over the stock numbers our dyno showed.
@@jxkx4769 before you assume, please realize it took HP tuners 2 different attempts to fully unlock that PCM after we shipped it to them over the course of three months so that our in house tuner with 22 years experience using their software could attempt to write a map and timing table for this truck. He wasn’t able to lock it in gear during the pull and had to roll into it.
@@Day1Mechanic thats not much to brag about then i was actually assuming the best for you why go through the trouble of tuning and even prepping for dyno if you have hardly any gains
That’s pretty low. Mine did a lot better in the Florida heat on a mustang dyno. I will be getting long tube headers soon and then dyno again to see if there is improvement
Yeah it’s a 5.3 truck with fairly low timing in it. A cam and more timing would have easily cracked 500, but this is the owners daily so he wanted to keep it tame.
That is very weak. My 6.0 LS with a very small cam (Texas speed stage 2 low lift truck cam) made 420 wheel. Completely stock L96 6.0 except for valve spring and the cam
Pretty sure this was a 6.2 truck. Few things to note about that: this was not pulled in its 1:1 gear due to the speed it would be seeing, the entire truck was stock except for the whipple kit, and this was only making 5 psi of boost.
Chart is pretty straight forward. It's just difficult to tune these new vehicles with their TCMs being difficult to work with. We couldn't get the truck to lock into a single gear throughout the whole pull and it wanted to shift every time despite what the tuner could do. He tried several things and basically rolling into the throttle allowed it to stay in 5th the best but it wasn't a typical WOT pull like we usually do. Also, these LTs are direct injected and the high pressure pump is cam driven so the stock cam is a limiting factor for the fuel delivery. It's on 93 octane so the timing is very much on the safe side, the pulley is huge so it made 5 psi max, and it has an entire stock exhaust system so its very restricted in the airflow department. Also, in another comment I stated that this was a 6.2l truck and it was actually a 5.3, so I was wrong there, and the numbers makes better sense.
@@Day1MechanicI have a '16 Sierra 1500 with the infamous 8 speed. But that could be put into manual shift mode. You just shift past D into M. Does that help with the dyno at all?

Meanwhile dodge, chrysler, jeep, ram has OEM factory super charged options for sedan/suv/truck, except a few.

@Parker565 mad at your ecoboost huh
@@GrapeYaInTheMouth it’s a supercharged 5.0L but feel free to call it an eco-boost if you’d like🤣
@@Parker5655.3s handle boost perfectly fine stock
"Long cool woman in a black dress...." dig it
Needs a cam kit and injectors obviously lol after that, it’ll be 600 hp!
Cam only actually. It’s a 5th gen LT1 so it’s direct injection instead of port injection.

@@Day1Mechanicdoes the ecm adjust for the super charger or did you have to have it unlocked to tune it
5.3 truck I assume? It’s not bad for the relatively low boost. It will make that 5.3 run with a full bolt on 6.2 truck all day long, so it’s definitely a solid gain over stock.
Yes it’s a 5.3 truck with relatively low timing since the owner said he may be traveling places where 91 octane is the highest available with it.
crank horse power is measuring from the balls, it always sounds better in the sales brochure. as far as actual WHP expect a 20-30% drop from crankshaft to wheels. factor in auto trans/ manual/ rwd/awd. hell even running different compound tires will effect a Dyno graph.
Will the 8 speed transmission hold a supercharger??
Literally my truck
How much do your install cost where are u located
So a 6.2 makes 420 horse and 460 stock. How does it only make 15 horse power more and and 53 ft lbs less with a super charger? Something ain't right at all. And if it is right, that was a complete waste of money
not tuned probably just actually slapped it on
The 420hp is at the flywheel not rwhp.

Is that thing getting enough air?
Where are you guys located ?
That’s pretty low. Mine did a lot better in the Florida heat on a mustang dyno. I will be getting long tube headers soon and then dyno again to see if there is improvement
That’s a 5.3 correct? Or its missing a couple of plugs
Yeah it’s a 5.3 truck with fairly low timing in it. A cam and more timing would have easily cracked 500, but this is the owners daily so he wanted to keep it tame.
Wtf pick one 5.3 or 6.2 .... on another comment you say that its a 6.2L...
That’s it?

Very anticlimactic.
Jeez why is everyone giving u a hard time. You’re literally just posting a build. You nevwr claimed it was a beast or coyote killer.
That’s not very good at the wheels.
