Unless your quarter mile racing I think it's asinine to use centrifugal supercharger. Not only do you have parasitic loss, but you don't get that boot in the ass you get from a positive displacement. It's like centrifugal superchargers take the worst of superchargers and the worst of turbochargers and make one unit and for some reason it's good for quarter mile racing LOL. But if I'm going to have a parasitic loss from a supercharger, it better give me instantaneous torque! Otherwise, twin turbos baby. Always going to be more power, as there is no belt drive. Positive displacement superchargers even though they are parasitic, they give you that instant torque hit even faster than twin turbos. That's why everybody says they are fun. You push the gopedal, and your ass just starts wiggling
In Australia the LSA & LS9 came in a HSV (Holden special vehicles) GTS & GTSR-W1 which are 4 door, rear wheel drive sedans based on the Commodore. I have a Commodore with an LSA swap, it’s a fun car.
In my 2010 VE redline Ute i swapped my L77 6ltr to an LSA and a Tremec T56 6speed and 398 diff gears heaps more grunt way cheaper than a Maloo same driveline my Ute is a Walkinshaw I kept all original parts in case I want to return it to original plate specs superchargers and forced induction is the way to go plus factory reliability
All VF11 come with an LSA except N/A ClubSport has LS3 ,to be honest HSV dropped the price by 5k to be more price competitive with the SSV Redline only 4k more if it was my $$$ I'd would have dropped the extra 4k, you do have SS fans though but so much value for that ClubSport and considering most SS buyers bolt on HSV/Walkingshaw "ClubSport bits and spend way more than 4k on basic upgrades and yet the ClubSport is MORE!
Thanks man. So glad someone explained the differences between different LS engines. If you don't mind I'd love to see videos about the Ford Ecoboost engines :]
So were the dry sump LS3s that went only into the Grand Sport manual coupes. The wet sump LS3s for the base cars, convertibles, and Grand Sport autos (or combinations thereof) were built on the normal production line.
You forgot the supercharged LT4 and LT5. LSA is also used in the Holden Maloo and the Holden HSV. The LSA engine was originally designed primarily for marine applications: it's a boat motor and also available from General Motors as a crate engine for projects. What's confusing is that the Chevrolet Performance videos say that the LSA is not intended for marine applications.
The LS9 has a shorter connecting rod than the LSA. The LS9 rod is 5.990in and the LSA rod is 6.098. Therefore there are also differences in the piston dimensions.....
@@smythtaylor7272 how can it be if the rod is 0.108 longer? And the pistons are supposed to be the same, unless the crankshaft somehow eliminated that math, the stroke would be longer throughout the piston travel?
Centrifugal supercharger is a totally different animal. it's more like a turbocharger. these have positive displacement superchargers which produce boost in a different RPM range and behave differently than a centrifugal supercharger
@@SixTwoHemi no they aren’t. They don’t run off exhaust gasses. That’s much more akin to a supercharge hence why it’s centrifugal supercharge, they are belt driven
Not sure your statement on superchargers is entirely correct. Positive displacement superchargers have a very different response to that generally offered by a centrifugal superchargers. This can be both good & bad but it depends on what you want to use it for. Peak numbers aren't always the entire story.
Great video: I want to specify the LSA had 2 applications. It was in the 5th gen Camaro ZL1 and the CTS-v2 (CTS-v1 had the LS6 and the CTS-v3 has the gen 5 LT4) Also, does the LS9 have piston oil squirters? I know the LSA does. Just curious if you have that bit of info.
Okay so ibought my exwife her dream car a 2015 ZL1 LSA 6spd auto she cant drive a stick. I dynoed it in hawaii once we bought it cuz thats where we are from, than move to washington state it has less than 50k miles on it cuz i dont allow her to drive it but. At both places the car only made 525hp&525trq, and was never able to hit 9psi we only got 7.6psi
I'm building up my 2017 Chevy SS sedan, a.k.a. Holden Commodore, and I'm considering the LS9. In fact, it's the only blower configuration that I like. I grew up with 440 and 427's, and I would prefer one of those vs. a boosted build any day of the week.
If you swapped in an LS9, you'd have the closest Chevy SS (Commodore) in the US to a HSV GTSR W1, Australia's fastest, most powerful and most expensive car, ever.
900whp isn’t a lot for a stock bottom end Ls with a forged bottom end. SBE 5.3s make 700-800whp with no problem on cast rods. Forged rods would be fine over 1200hp
The ls9 has the sangre technology as the ls7 with the titanium and sodium filled stuff where the lsa doesn't. I'm not too knowledgeable on Chevy stuff but does this mean the ls9 might or does suffer from the things the ls7 owners reported on their stock c6 zo6's? Holes being burnt on cylinder heads, engine swallowing a piston, etc.
We in Australia have the gm holden hsv gtsr w1 which has the ls9 in it and is Australia's fast ever production car look it up and you will be impressed
The gen 5 LT2 in the C8? Curious why you would want to compare a naturally aspirated 6.2 to a supercharged 6.2. I feel like an interesting comparison is the LS9 vs the gen 5 LT4. Based off of port injection vs direct injection as well as the blower size and other key factors.
@@zillamill yup, lsx us gm's aftermarket LS based block/heads, however there are the crate engines which I believe are hand built LSX376 & LSX454 Wonder if u could build an LSX454 with an LS9 style supercharger kit too it... wonder what that would be like
AYUCHTUALLLY Your count at 6:45 Is wrong. The LSA was used in 5 different General Motors models: the Chevrolet Camaro ZL1, the Cadillac CTS-V, the Holden Special Vehicles ClubSport R8 LSA, the Holden Special Vehicles Maloo R8 LSA, and the Holden Commodore GTS. The LS9 was used in 3 different models: the Chevrolet Corvette ZR1, the Holden Special Vehicles Commodore GTS-R W1, and the Holden Special Vehicles GTS-R W1 Maloo. (You’d be forgiven for forgetting about the HSV GTS-R W1 Maloo because they only made 4 of them, one recently auctioned off for $550,000) but the others are inexcusable.
I have a GM 6.2 aluminum block with casting number 12621766 and 30455 on the other side. I’m confused on what I have. Can anyone enlighten me please? Thanks.
Technically it's an LS3 but it's not on the same level as the LS3 in the Corvette no Supercharger so it's not an LSA. You could add the blower and a few other parts and get it to be like in LSA.
Not quite you can start with the block and the internals get ls9 heads were better than ls9 heads and add an ls9 blower but then again you could get the big Whipple or Magnuson blower and that is bigger and puts out more than an ls9 blower

i have a GTS with a LSA :)
LSA was also used by HSV for the Maloo, Clubsport, Senator and GTS. HSV also used the LS9 for the GTSR W1.
LS3 in the grand sport was hand built, as well as the LS7.
Only in the Grand Sport coupes with a manual transmission.
@@ScottO84 yup, autos and convertibles didn’t get dry sump
Great video. I do wish GM put forged internals in my LSA.
I believe the LS7 was also hand built in Wixom Michigan.
Yep, came here to say the same.
LS9 was also used in the HSV GTSR W1 and the LSA was used in the other HSV range from the GenF and GenF2 series like Clubsport, Senator, GTS, Maloo
Thanks man. So glad someone explained the differences between different LS engines. If you don't mind I'd love to see videos about the Ford Ecoboost engines :]

Yeah, that's what I thought and came to comment.

You actually said it yourself. The RODS measure different…the piston sitting on top of the rod is the same. The difference would be in stroke.
@@jasongaudreau2075 the stroke is the same.
@@smythtaylor7272 how can it be if the rod is 0.108 longer? And the pistons are supposed to be the same, unless the crankshaft somehow eliminated that math, the stroke would be longer throughout the piston travel?
Read above. Piston dimensions are different.
They also use the LS3 block for the LS9 due to the cylinder walls are different as well. They handle boost better.
Centrifugal supercharger is a totally different animal. it's more like a turbocharger. these have positive displacement superchargers which produce boost in a different RPM range and behave differently than a centrifugal supercharger
It’s not more like a turbocharger as a turbo runs off exhaust gases.
@@zethloveless7238 technically is right but didn’t word it correctly. Centrifugal blowers are basically belt driven turbos.

I recommend watching this video at .75X speed.
Thanks
It seems fine at normal speed maybe pause if you are trying to read something specific but I watch most things at like 1.25x some at 1.5x
MVP level assist
Will the LS9 supercharger fit on the LSA engine ?
It should the lsa should fit on an LS3 and most people use them with adapters and put them on gen3 like 5.3l or 6.0l truck motors
@@james10739 Thanks !
Yup
By the time you find and pay a premium, you could buy a Kongs 2650

Yes I can 👊
@@Dustrunnersauto oooooh is that what the next vid is gonna be?
We'll see. There are so many videos I want to make, but only so much time to make them.
Awesome review 👏 but the LS7 is hand built too i believe???
Sure is. As well as dry sump LS3's (manual trans Grand Sport Coupe).
Great video: I want to specify the LSA had 2 applications. It was in the 5th gen Camaro ZL1 and the CTS-v2 (CTS-v1 had the LS6 and the CTS-v3 has the gen 5 LT4)

I own a 2013 V and was considering to swap my LSA with a LS9.
Just stroke it
I need to replace my camshaft and lifters in my 2011 cts v. Should I buy a different camshaft other that stock?
@@link6397 yeah you should, youre gonna need all the supporting mods aswell.
Later model LS7 that was on the Camaro Z28 is also hand build

Always love your videos it's so informative. You should consider semi-truck engines.
Could you do a lt4 vs ls9
Cheers 🏁
And lt5 too!
Great info.. thank you for the video!
LS9 is king daddy have to admit.
Thanks for the video. Still LOVE my V! LSA or not! Stupid Fast!
The grand sports ls3 was also hand built
900whp isn’t a lot for a stock bottom end Ls with a forged bottom end. SBE 5.3s make 700-800whp with no problem on cast rods. Forged rods would be fine over 1200hp

We in Australia have the gm holden hsv gtsr w1 which has the ls9 in it and is Australia's fast ever production car look it up and you will be impressed
I live in Australia too, and I really miss Holden, and HSV. General Motors, killing off car brands since forever.
Can you do a LSA Vs LT2 comparison in a engine swap which would give me better performance. The lsa has higher hp but that’s not all that matters
The gen 5 LT2 in the C8? Curious why you would want to compare a naturally aspirated 6.2 to a supercharged 6.2.
I feel like an interesting comparison is the LS9 vs the gen 5 LT4.
Based off of port injection vs direct injection as well as the blower size and other key factors.
great video . can make some video about V6 pushrod engine
Great video. Where does the LSX fit in? Like an LS9 w/o EFI?
LSX is entirely aftermarket type of stuff
@@zillamill yup, lsx us gm's aftermarket LS based block/heads, however there are the crate engines which I believe are hand built

LSX is aftermarket iron block sold by GM

Are you sure both aren't 15 degree heads?
Will LSA/LS9 supercharger bolt on a 4.8/5.3 Vortec with LS3 heads? With forged H rods and pistons.
The ls3 heads require a larger bore than 4.8/5.3 block can be punched out without resleaving. Common on a 6.0 block though!
100% the Ls9 blower will bolt right up to a LSA motor
1:25 There's no way I'd consider the ZR1's 2.3L TVS "kinda ehh"... even in 2022.
why might be the reason he's considering them ehh? are aftermarket tech/ efficiency really that more superior?
how about the LSX?
I thot chevy ss got lsa?? Or was it lsx??
Technically it's an LS3 but it's not on the same level as the LS3 in the Corvette no Supercharger so it's not an LSA. You could add the blower and a few other parts and get it to be like in LSA.

Good
1000 HP
reason for bolts 11 and 12 the is made stronger the the added hp on heads
Oil squirters....
The Ls9 block has a wrinklepin by the fanastan. The Lsa doesn't.
Why am I even here?? Rotary is my heartbeat
I’m a sucker for an ls with a fat turbo lol
@@mackmuhlbeier4531 I would rather prefer ls9 with a supercharger
So basically I can build an LS9 out of an LS3 with just a cam swap.
Not quite you can start with the block and the internals get ls9 heads were better than ls9 heads and add an ls9 blower but then again you could get the big Whipple or Magnuson blower and that is bigger and puts out more than an ls9 blower
