- TURBO VS COMPOUND BLOWER/TURB0 VS NITROUS/BLOWER! WHAT MAKES THE BEST BOOST? GEN V M90 SUPERCHARGER OR LOW-BUCK, EBAY, GT45 TURBO? HOW MUCH POWER DOES IT TAKE TO DRIVE THE M90 SUPERCHARGER? HOW HOT DOES THE BLOWER HEAT THE AIR? WHAT HAPPENS WHEN I RUN A 2.6-INCH BLOWER PULLEY? HOW MUCH BOOST CAN I RUN ON MY 3800 V6? CHECK OUT THIS VIDEO WHERE I COMPARED TWO LOW-BUCK BOOST BUILDERS ON A MODIFIED 3800 V6. HOW WELL DOES THE M90 SUPERCHARGER COMPARE TO A SIMPLE TURBO? WHICH ONE BUILDS BOOST QUICKER? WHICH ONE MAKES MORE POWER? WHAT DO THEY EACH MAKE AT THE SAME BOOST LEVEL? PLUS-BONUS TESTS-TURBO VS COMPOUND VS BLOWER & NITROUS!
In Australia we gun the GTX3584RS turbos on these motor and they are perfect size for them. Will easily hold 600 wheel all day
What rpm does it light that turbo typically?
Hahaha all day?! like to see it at the end of day lol .small pully DONE! roast ya at every lights. We still talking street driven car and just for the $ spent ?
@@r0bkills yeah righto, your air intake temps will fry your motor… but that’s all good
I’m very jealous you all have the L67 in RWD applications
The L67 can make so much power here but it’s hard to find a transmission to hold up.
Drag race, turbo. Driveability power for your regular daily driver, blower.
Just my opinion. That instant low end power is amazing.
True
Blower on the street rod/hot rod/pro touring track car. Daily it's turbo for reasonable economy and still brutal fast. Blowers and long trips don't really agree.
would love to see you re-visit the compound setup with the optimised setup (cam upgrade, heads improved, open up that blower intake etc) before the big bang.
NO NEED-THE TURBO WILL DO WHAT WE WANT
Hardest working man on youtube!
This video is what we been waiting for 💪🏿💪🏿
A GT35 would light off nice and quick and make more hp than any fwd could hook on the street.
I a t70 and even at just 16 PSI it is too much on 235 sticky tires
Running a ls4 with a s366 on 275s and it hooks surprisingly well
i wanna see a j35 from a honda odyssey.. i wanna see cams compression i've always felt like that engine could make great na power and amazing power adder number... just a though
I HAVE j SERIES INFO COMING
If we are looking for boost response, the Ford 3.5 Ego Boost is amazing. With their small twin turbo setup, there is response at 1600 RPM. The 3.5 feels like there is NO turbo lag. Power response is as good as any super charger
Thats expected, it uses Tiny turbos.
Tiny expensive turbos that like too pop.
I think it would be really cool to optimize the super/ turbo combo. Like does the turbo blowing into the supercharger decrease the charge temp of the supercharger, making it more efficient? I bet others would be interested as well.
it makes the blower more efficient-but dramatically raises (compounds) the boost (which raises the air temp)
Some have, they begin to have diesel like power curves with huge tq and not as much hp. Something like 800-900 ft lbs and 600hp
The supercharger becomes a restriction when the turbo really gets going. Ideally you want the supercharger to cover low rpm before the turbo spools, then you want to bypass the supercharger and use the turbo. If you could disengage the supercharger all together too that would remove it’s parasitic loss as well.
YOUR THE KING 🤴 TESTING
Hey Richard me again...they supercharged 3800 would be a perfect candidate for a liquid co2 injected intercooler and just wire it like a nitrous system and tig weld a few fittings to the intercooler would be interesting to see
It's not his intercooler, he borrowed it.
The snail duh, m90s are so inefficient
Keep in mind: M90 just was not designed to make that much power. It can, but not efficiently. Any blower or turbo will look bad when you use it outside of it's efficiency range. That turbo is more comparable to a supercharger about 2x the size of the M90.
Where o where is Eric Weingartner?
Good information
Really making me want a supercharger for my 5.3 instead of a turbo
Turbo bro!
Love this 3.8L work !!
Before you add ring gap for the big bang can you tell up how close the factory ring gap is to your boosted ring gap formula.
Fyi i do remember you mentioning ring gap varies from factory with the same engine.
Still would be interesting to know.
Thanks!
I will let you know what it is when I disassemble
Great video 👍👍👍
Thank you very much
There is so much great info
My dream is to have a 3.8SC in my Fiero Chop Top project
I would love to see what an intercooled 1.9L TVS supercharger would do on this 3800 V6. Also its best to have the supercharger blow into the turbo inlet in a compound setup. The blower creates way too much restriction when the turbo is blowing into it and you loose the multiplication factor of feeding a turbo a boosted charge. Maybe do a test and post the results.
I think I can speak for everyone we want to see Jackie doing no prep with the Cadillac
Wow, this video is chock full of good info! Just out of curiosity, will you be trying compound turbos on the 3800?
I did a turbo/blower compound on the 3800 already
Yeah, I saw that video. IMO it would be cool to compare / contrast that to compound turbos.
Actually it time to see the best cam vs Truck Norris… pleeeeeeeeeeease!
Lol i’m waiting for the same video!!!
I heard a rumour that its low.end is pretty poor.
You did post lots of pics of that gt3582... ;)
Noticed the peak hp blower low psi vs high psi. Looks like it starts to fall off hard, and at 300rpm earlier.
Ive got a Lexus gs400 with a 4.0 v8. Ive been trying to decide between a turbo or a m112 sc. This decision just gets harder and harder😂
Another thing super interesting is that all of the accessories are in place. Very uncommon on the dyno.
Is there a short video of the turbo build featuring how the supercharger plenum was gutted and sealed?
remove rotors and make a plate to cover the end of the blower casing
I'd like to see you make power out of a 90s 3.4 camaro motor or an 80s 2.8
He turboed a 3.4 before on here for a grand am I think?
It was really wild. And I totally agree. I’d love to see him do a 3100 from the beretta (or similar cars)
3800 is pretty impressive. But those FWD transmissions are deplorable. My 2000 GTP Grand Prix made the trans a slushbox
How are back to back pulls on the supercharger does it lose power due to heat
temp does go up
Just subbed
welcome
Would love to see this same comparison with a twin screw supercharger.
check out the video on the mod Ford where I ran twin screw, roots, turbo and centrifugal
What's some good cars to look out for a cheap junkyard turbo?
turbo diesels
Dual M90's?
If that GT45 is only good to 800 you may need a bigger turbo to big bang the 3800 ;)
Great comparison
thnx-we have an s475 and vs racing 7875 standing by
@@richardholdener1727 love to see it!!
How are you tuning this engine I’ve been trying to swap from supercharger to turbo for years with my bonneville
HOLLEY HP
Hey I remember once you said you couldn't run the chevy 3.9. I was just curious why. Same bolt pattern as a 3.8 and it runs on a e38 ecm on the one I've got on my rail buggy. I'd like to do some turbo stuff on one but curious what the power would be. Factory rated at 243hp N/A. Also love all these videos. You're the reason I went from a 14:1 383 to a stock 6.0 with a turbo and water/meth in my rockbouncer. So I'd also like to say thanks!
What are the differences between the s/c engines and NA versions? I have a 3.8L Camaro and would love to have 500ish unsuspected horsepower! LOL
Hey richard can we do same test but turbo vs centrifugal supercharger at same boost? Would be nice to see the difference in graphs at same peak boost between all types of boost. Maybe on an ls for more fun lol.
please see the videos that are already up-tested turbo v roots v centrifugal v twin screw
Do you have a ported supercharger? That would be interesting to see as well
NO SIR
can you use the Gt35 but use the numbers from the blower from the video
Hey Richard, what do you think about an old 6.7 powerstroke turbo on an iron block 5.3?🤔🤔🤔 I have the motor (3 actually 🤷🏻♂️😂), and the turbo was free. I think I even have a second one laying around as well…
I would like to know this as well
It can't hurt 🤷🏻♂️🤘
use 2
I’ve always been told that an M90 is a heat pump.
How about a blower with a split sheave pulley so it can automatically spin faster at higher RPMs in order to keep up with the engine demands?
the design of the blower is the issue-not the speed
What about centrifugal blower Richard? How would this compare in this same scenario... also, which one would you choose belt driven or electrical?
The turbo would. No parasitic loss from spinning the centrifugal blower
electrical?
TH-cam is on some good drugs. This is not the comment I replied to. Lol
👍💪
Figure out a way to run the supercharger air through the same intercooler you use on the turbos. That big unit gives the turbo a big advantage.
THE TURBO GIVES THE TURBO A BIG ADVANTAGE-IT'S NOT THE COOLER
@@richardholdener1727 No doubt. I know that the old Eaton 5th Gens barely break 60% efficiency, and turbo's generally aren't even mapped below 65%. If somebody is matching a turbo to their engine and ends up running below 70% efficiency, they have the wrong turbo.
But what is the relative effect of the two? Gale Banks did some good testing of that in his Killing A Duramax and Building a Monster Truck series of videos. At the ~40 psi boost he was running, the intercooler contributed about an equal increase in density as the turbo.
But the final intake temperature of 131F with the intercooled Eaton supercharger is pretty hot for an intake manifold temperature. Taking another 45F out of the intake air would give a worthwhile gain.
what injectors did you use?
80s
Personally I would choose the blower. Because drivability and being all in from idle is what makes a fun car to drive on the street
Until you take one of these cars and turbocharged it. And then you never look back.
The street manners are almost no different. And when the turbo runs at full Boost, it pulls much harder with a longer area under curve than the blower does. I know, I smoked my buddies fully built supercharged GTP with my bolt on turbo kit Regal
@@BoostedSpeedDemon I personally own to turbocharged Hondas I used to have a DC2 with a Jackson racing twin screw supercharger kit full stop that thing was more useful from idle to 3 grand then my fk8 stock turbo and my da9 although it has a 3582 which is a tad too big for a 2 l lol
@@BoostedSpeedDemon obviously turbocharging is better for all our power but from light to light and corner to Corner the response of a belt driven compressors just a little better
@@b20vtec83 race car drivers learn to drive around the turbo lag, from corner to corner. That is, if the turbos are properly sized.
What was the outcome on the ported heads. I seem to have missed that report!
they added no power
A TO4e or GT35 turbo would be better for low end torque.
T70 58mm is perfect.
First!!!!!
What size was the injectors and fuel pressure 👍
58 psi static and 120s
What engine are these being tested on
3800
What kind of fuel economy is associated with boost turbo.
I don't test fuel mileage on the engine dyno
Richard anyway to get ahold of you? Ever done any remote tuning?
I'M NOT A TUNER
@@richardholdener1727 10-4
I'd not put much faith in an M90 spinning fast enough to make 335kW lasting for long...
I have ran a 2.7 inch pulley on mine for the last 30k miles with no blower issues. Blower has 160k miles on it
I run my polished M90 1 2.5" pulley on an ATI 7.15" overdrive balancer, getting the pulley to about 2.25", all day long for years on E85 for a maxed out L67 for over 400 to the ground daily.
Yeah a gt35 would have made way more toque
you should have used the GT35
Personally I blame squirrels
Howdy Richard. Real quick again thank you for the idea and recommendation to go with something like the M122 supercharger in my supra it’s gonna be a great combination I’m working on getting it installed as soon as it starts getting warmer here in New York. If you could what is your email address I have a question for you. 🤙
killerbe16@ao.com (add NOS to the blower)
@@richardholdener1727 Absolutely😁🤙
