- FULL DYNO RESULTS-SBE LS1 VS SBE LS2. HOW WELL DOES THE LS1 RESPOND TO BOOST? HOW WELL DOES THE LS2 RESPOND TO BOOST? DOES THE LS2 MAKE MORE POWER THAN AN LS1? WHICH LS IS BEST FOR BOOST? HOW DO THGE LS1 AND LS2 COMPARE FOR POWER? WHAT HAPPENS IF I ADD A CAM TO THE LS1 OR LS2? CAN I RUN A VORTECH SUPERCHARGER ON THE LS1? CAN I RUN A VORTECH SUPERCHARGER ON THE LS2? WHAT HAPPENS TO BOOST WHEN YOU RUN A SUPERCHARGER ON A MORE POWERFUL NA MOTOR? CHECK OUT THIS VIDEO WHERE I COMPARED AN LS1 EQUIPPED WITH A COMP XR265HR CAM TO AN LS2 EQUIPPED WITH THE SAME CAM. I THEN COMPARED THE CAMMED LS1 TOT HE CAMMED LS2 WITH THE SAME VORTECH SUPERCHARGER (SAME PULLEYS, AF AND TIMING). WHAT HAPPENS TO POWER AND WHAT HAPPENS TO BOOST?

Be cool to see the overlay of the ls2 vs the 6.0 truck motors. Just to see the difference in the actual tq curves of a performance engine vs a truck engine.
There is one thing that has always intrigued me about the 346 lS1/6 engines. They seem to be over achievers, and they get substantially better gas mileage than the 4.0 bore engines. Back when c5's were new we were spraying the crap out of them and when guys would nip number 7 piston they would swap in a 6.0....the cars were never faster and in most cases slower. Once we got older and had more play money and got into Superchargers....the bigger engines did run better. I love me an ls1/ls6
Have a LS1 in my Chevelle, and I always thought I would never go 6.0 maybe 5.3 for general fun?
@@timschrock23 Leave the LS1 and hang the cheapest Vortech swap centri kit on it and be amazed and have zero issues.
Considering the 6.0s are iron blocks...
@shadowopsairman1583 LS2 is aluminum block you goober
Love from INDIANAPOLIS!!! hello and thank you for the Awesome content!!
Thanks for watching!
Love my notification bell
I'd love to see good comparisons between the holley low ram, btr equilizer, high ram, tbss. I can't seem to find much comparing them on similar setups. Your 20 intake cathedral test has high ram and tbss.
a TBSS would be better up to 7000
👍💪
I wish the used the ls6 to go head to head with the ls2 since the stock hp/tq is about as close to each other as any 2 LS engines have ever been
This may be good ole internet folklore, but I heard the LS2 took place over the LS6 in the CTS-V because GM recieved complaints that the LS6 idled "too aggressively." Since the LS6 has a "hotter" cam compared to the stock LS1. The LS2 made the same exact power as the LS6, but with a "smoother idle" and the power difference made up by displacement.
Again, probably good ole folklore I read long ago when I was browsing the V forums, but if that is the case I think it's hilarious. Because that has to be the most boomer complaint I've ever heard... "My high performance sports sedan idles too rough 😡"
@@OctaneSlain that’s definitely interesting I didn’t know the 1st generation ctsv ever came with an ls2. I thought they were all ls6 cars for some reason.. love the ls6 in my 03 z06!!
Interesting. I thought that the power outputs would be closer because the blower is providing the same amount of air. Is the loss from heat?
the blower is not providing the same amount of air
So is the LS1 factory crank, rods and gaskets or are the aftermarket parts as well?
BOTH WERE AS DESCRIBED
Would a LS6 vs. LS2 be a toss up?
405-hp LS6 would make less through most of the curve-except at the peak
I have am Xer stage 3 cam in my auto (sadly) 2000 C5 corvette, with long headers and full custom exhaust, LS6 intake. Makes 409rwhp and around 535nm wheel torque. Somehow it made more torque than your ls1 in this video.. It was run on 98 octane.
how do you compare rwhp to fhp? The answer is you can't
@@richardholdener1727 Converting rear wheel horsepower (RWHP) to frictional horsepower (FHP) involves understanding the losses associated with the power transfer from the engine to the rear wheels. FHP represents the power lost due to various frictional and mechanical losses in the drivetrain which can include losses in the transmission, differential, axles, and other components. The formula for converting RWHP to FHP is: FHP = RWHP / Drivetrain Efficiency
Determine the Rear Wheel Horsepower (RWHP): This is the actual power measured at the rear wheels of the vehicle using a dynamometer or other power measurement tools.
Find the Drivetrain Efficiency: Drivetrain efficiency represents the percentage of power that is lost as it travels from the engine to the rear wheels. It accounts for various losses, such as friction in the transmission, differential, and other drivetrain components. Drivetrain efficiency typically falls within the range of 85% to 95% for most vehicles, but it can vary depending on the specific drivetrain design, condition, and quality of components.
Calculate Frictional Horsepower (FHP): Divide the RWHP by the drivetrain efficiency to calculate FHP
For example, if your vehicle produces 250 RWHP, and you estimate the drivetrain efficiency to be 90%, the calculation would be: FHP = 250 RWHP / 0.90 (90% expressed as a decimal) = 277.78 FHP
So, the frictional horsepower for this example would be approximately 277.78 FHP
How much HP can the ls2 block handle?
we don't usually go over 1000 hp with LS1, 2 or 3 blocks
Just left sitting in my car have to go to hardware
With the same mods the ls2 will always make more power 😅
The LS1 is the holy grail! And far as iam concerned, runs better than the rest!
Ive had a stock LS1 and then ran it with a summit cam for 2 years. The LS1 sounds the best but the torque and power my currently stock LS3 are much better.
I loved the ls1 in my old 2002 ws6 but my 07 base corvette with the 4th gen ls2 has given me more power with less problems
But it's literally the second worst
I’ll keep my 468 --“ ❤
I will keep my iron block LS1
I’m not sure what kind of math you are doing but 710hp minus 675hp equals 35hp. Not 45. Hate to be that guy, but accurate numbers matter.
WHEN YOU LOOK AT 99 THINGS THAT ARE CORRECT AND 1 THAT IS INCORRECT AND FOCUS ON THE 1-YOU ACTUALLY ARE THAT GUY!
you are a silly goose
@@sniperpronerfmods9811 lol. Why?
@@richardholdener1727 well I guess so. No need to get so mad about it. As smart as you are, I figured you could get that wrong! 700-675 = 25 + 10. Easy to do in your head instantly. You know, because you said 45, and I trust what you say, even though I knew it was 35, I STILL double checked with a calculator. Because in your defense, I didn’t want to believe you were wrong.

LS1 = LS FUN! :)
