Id love to see this test on the 3800. See how much of a difference a bigger tb + ported inlet makes. Going from a 65 mm tb to like a 102 or something, port matched and all.
Crazy idea, could you use two of those superchargers blowing to the middle? Like rotate one 80 degrees left and the other 80 degrees right so they blow down into a 20 degree downward V into the intake manifold. I know the fabrication would be more difficult but then you'd have double the displacement and won't need smaller pulleys.
A square edge pipe inlet will only flow 72-82%. A radiused inlet will flow 97%. I was blown away when I read that on a Honeywell engineering document a few years ago. A square pipe edge creates turbulence reducing flow. I'm really interested to see your next video with the bellmouth inlet. BTW, they make bellmouth intakes for HVAC systems. It's amazing how much an inlet is quieted down with a proper inlet.
I remember back in the forum days everyone said this SC was too tiny to make any power. That it was only capable of 250HP at the most, and way too small for a V8 😂 Thanks for proving all of them wrong.
How about a junkyard turbo build where you use a turbo, intercooler, etc. all salvaged from other vehicles. Like run 6.2 flex fuel injectors in a 5.3 with the turbo off a duramax and see what happens🤷♂️
This is absolutely great. Thank you Richard. Given your collection of intercoolers for your turbo builds, why not try an intercooler on your M90 build? Given the difference that N2O made I wager this would be another non trivial improvement!
I had a 2000 Buick Regal GS supercharged 3800 this same exact supercharger I missed that car that's crazy if they fit on LS4 Motors though never thought about it
Would love to see this blower strapped to the LV3 4.3 V6, I've honestly fallen in love with the motor and would love to see a big bang of one maybe some day!
Phenomenal thought provoking info Richard! Does the final comment indicate that you may try this little blower on your LY6, or some 6.2L engine at some point? That would be interesting in light of all of these other surprising outcomes so far...
NO.....most diesel terboz have a max TIT of 900*C and for gas motors that is a bit low and they can have short lifespans if over temp'd....unless we run E85, that is :D !!!!....and big diesel terboz are...well....BIG and oft times pretty inefficient and/or have odd pressure ratio issues..... you can get late spool and poor performance unless you get the right ones...and on and on@@williamrouse3033
I wonder what the design max speed of that blower is vs what it's being spun to now? It might be reliable regardless, I dunno. I'd just hate to do that and then blast a bunch of rotor shrapnel right down inside a motor...
I’m wondering at what rpm does the bottom end come apart??? Most likely valve float will act up before the bottom end comes apart unless it gets beefed up.
So on a 6.0 truck engine "Boosted" Is it worth going with double springs for more lift 600+. Or just use the BTR beehive springs I have. And find a cam with more duration. It's got the sloppy stage 2
Richard I hope you had a great Thanksgiving.. I’ve seen your video on different size Intercooler and piping, but I wanted to ask have you ever done a video on: Ambient Air Temperature effects on Boost Pressure? If so, can you please let me know the title of the video? Thanks Much
would be a great swap combo into a beater in Pennsylvania with an Antique license plate . Say square body S10 with a hole hacked in the hood . Add a 100 shot and have smiles
Considering the lv1 is a ls based lt V6 unlike the LU3/L35, it should respond as well as the 4.8 LS, but even a LU3 4.3 with a turbo has known to snap the 10 bolt rear axles.
Nice work Richard! Those are good numbers. Can you say how much that setup costed from throttle body to pan? Not including fuel injection and computer.
I have a 87 chevy g10 van with a 305. I have access to a 350 or I can pick a chevy 2500 chevy truck with a 5.3l ls I could body swap. Onto. Would it be cheaper to build a 400hp 350 or swap the frame with the 5.3l 4x4 with the a m90. For 400hp as thats my goal hp
Hey man I have a blower which has an identical displacement as as the m90 tho it's a old school roots blower. How much power would I be loosing by sticking with a roots blower instead of the twin screw?
@@richardholdener1727 my bad 😅. So the m90 is a twisted 3 lobe and my blower is a straight 2 lobe. How much power would I be loosing by sticking to the 2 lobe?
Any motor can be run with boost-maybe they meant it won't bolt right on because the 3.7L doesn't have the same intake-you would have to do some fabrication to mount the blower
3.8 V6 guys have done it and roush using the Eaton m90's have done it in mustangs as well. The blower won't live long overdriving it that hard and it'll create a lot of heat. However it's nothing new. Also you have to remember it's flywheel HP not rwhp. So figuring at about 18-20% drivetrain loss it's making in the range of 400hp to the wheels. Is it the most efficient way to make the HP? Not remotely.
@@richardholdener1727 I always wanted to use a budget supercharger in a compound setup on my 12 valve cummins diesel mustang. Supercharger like this to increase Volumetric efficiency basically linked to rpm would be great.. i could have boost easily and quickly when i bump into the stage beams.. and it would help to simulate a “bigger engine” to spool a bigger turbo charger like an S475 or 480. typical cummins compounds need to cram all the exhaust gas through the smaller manifold charger and it’s gate.. the supercharger would not have that exhaust bottleneck. is there “compressor maps” for the M90? I wonder what pressure ratios it can handle.
Richard, you can increase the diameter of the opening on the bottom of the Eaton for increased flow. Probably still lots of info floating around the interwebs from the good ol' days. ps - why no intercooler?
Glad you did the header test, because you know there were going to be at least a few crying foul. 537 HP is quite promising from what you started with. 👍
I wish you would have actually spent some time on the HOW part of the video title…would love to know what all is needed to put the M90 on a stock 4.8 Silverado to make it a better truck, not a hot rod.
@@richardholdener1727 so the blower picked up maybe 50 peak hp? Lots of midrange gains through the middle vs a hiram cam 4.8? Seems like alot of work for small gain. Would a stock 6.0 make similar midrange and peak #s as the blower with a smaller cam?
@@bly4233I’d still like to see it, just to find out what kind of setup Richard comes up with. Shame GMC didn’t have more race parts for the 4.3, especially with the Syclone and Typhoon out there.
4.3 has offset rod journals to smooth out the uneven V6, but those are the weak spots. I had a friend break one he only hauled his family around in. Not to mention, they have an unreasonable amount of intake manifold and oil pan leaks.

So tell me what percentage of gain I can expect. I'm contemplating doing this on my '03 Sonoma SLS 4.3
you have a 200-hp v6-we have made over 450 hp on a v6-so you can gain a lot
thought about running one of these on an old 5.0, everyone keeps saying it wouldnt be enough blower. clearly it makes enough to break a stock block?
it doesn't make enough to break a 5.0l block
