CHEAP E-BAY TURBO VS JUNKYARD M90 BLOWER-4.8L TORQUE FOR TOWING. GT45 TURBO VS M90-WHICH WORKS BEST?

[@BocaChevy]

I have a small turbo 4.8 Silverado built for towing so I have some insight lol. I would say that a properly sized turbo will outperform a blower in almost every scenario. There is a reason why the Ecoboost, hurricane motors, and every modern diesel uses turbo for low end torque. The only benefit is that instant torque but I can make 10psi by 2200 rpm which is more than enough to move 15k pounds. Great video again!

[@hydrocarbon82]

BOTH! I'd love to see a twin-charged setup. The SC would just be creating a pressure ratio, so adding 5-10psi to the inlet with the SC at 5psi would net 11-18psi but with instant torque.

[@ThePaulv12]

That's what I was going to say.

[@richardholdener1727]

[@hotdog9262]

[@Russell_and_Rosko]

Word!

[@builditinyourgarage7826]

This is a great video, but most people want to tow under 3000 rpm due to engine noise and comfort in the vehicle. I know that it is very difficult to dyno that low, but I would really like to see the difference between horsepower/torque between 2,000-3000 rpm level.

[@killshot7041]

The nice thing about the blower is that it should fit under a cramped hood like a corvette or an ls swapped miata easier, anywhere else where you can move the exhaust around, mount intercooler, piping, etc the turbo is a better choice

[@BigBlackJerome]

I appreciate this channel more than words can describe. Please don’t ever stop making these

[@wudntulike2no32]

Every person I know that tried the eBay turbo route had to pull it back out very shortly afterwards. Sometimes the turbo went out and manifolds were always cracking. Maybe the supercharger has better reliability. Maybe.

[@jaydubb71]

You already know my choice. TURBO BABY!

[@erikmcmillan1947]

Have you thought about compounding the turbo WITH the supercharger? Get the best of both. You did this with the 3.8 and i was impressed, so I think a bunch of us would love to see you try it with this set-up, with this engine. Jyst a thought. Many thanks for all your work.

[@jrorie72]

Exactly what I was about to post lol

[@thewacokid0000]

The mechanical complexity just isn't worth the hassle. A properly sized turbo is better in every way without the complexity of building a bypass-type setup.

[@erikmcmillan1947]

@thewacokid0000 That really isn't the point. The point is to learn if it provides lower end torque for towing while providing the higher end power as well. After all, that was the question proposed and the entire reason for the test to begin with.

[@thewacokid0000]

​@@erikmcmillan1947the turbo wins for towing too

[@richardholdener1727]

already done on the 3800-look at those results

[@thewacokid0000]

We just went through this - the wife has a 2000 Tacoma with the 3.4L. We originally supercharged it with the Magnuson kit, 7th injector, etc - and it *sucked* to have to control charge temps by blowing fuel through the blower when running it at ~8-9 pounds. Recently after a 3000 mile road trip towing, trying to drive around the inevitable pinging (even with the timing controller to pull timing), we decided to go turbo. A GTX 3071R at 6 pounds is SO MUCH BETTER IN EVERY WAY. It spools low enough it doesn't matter. It makes more power. It can make *more* power without any worry of pinging thanks to having an intercooler. There is no comparison. Turbo every time over a roots blower. EVERY. TIME.

[@midnight347]

Sounds like that blower isn't very good must be a non intercooler kit to have that much issues at 8-9 psi? Either that or you're running crap fuel probably both. When you have an intercooler and good cooling system this isn't an issue. It depends on the application some applications have awesome options for those kinds of blowers some don't.

[@midnight347]

You can have a positive displacement blower with an intercooler too in the right application. Like I said this isn't an issue in every scenario. You're comparing an intercooler turbo setup against a non intercooler blower setup. Not even close to a fair comparison...turbo is going to make more power at any given boost level given they're the same size on same engine etc. That isn't a secret. It will never have instant response like a positive displacement blower. No matter how it's sized it will never have that ever. It also changes the exhaust sound. Turbo isn't always the answer for everyone and every build.

[@thewacokid0000]

@@midnight347 it was non-intercooled, yes. That's how the TRD kit works for the Tacoma. Fuel was fine. The 5VZ-FE doesn't use the knock sensors below 3000 RPM and because the MAF was pre-blower, it didn't measure the charge temps at all...so it would ping if you loaded it up heavily below 3000 RPM. Even with timing pulled and using extra fuel for cooling the charge, it wasn't enough. The response of the turbo is fast enough it doesn't matter. Even if the supercharger was intercooled (and I did look into how to hack one into the system), the turbo would win, especially up at 7500' where we live.

[@robrowland639]

I like the blower look, but where do I get an intake to do the M90 on a 5.3? You made a special plate to mount the M90 blower on a tunnel ram intake. Is that the only way to mount the M90? Very interested in you comments. And yes, a blower is much easier to install than a turbo for most people simply due to the need for routing tubing and the necessary welding. But anything can be done with determination. Keep up the great content.

[@spyker_aileron]

This is quite literally the video that i’ve been needing to see. I have an m90 blower i got from the junkyard for like $80 and have been debating with whether or not I should find a way to retrofit it to my application or run a cheap turbo setup. Thank you for this video. It is EXACTLY what i’ve been needing. And if you do actually see my comment i’d love to get your thoughts on the type of turbo i might get. I have a 1999 explorer 5.0 and really just want to wake up the motor a little to make it more drivable. I never really get the motor past 3,000 rpm, so i’ve been debating with my father about the size of turbo. I think it’d be better to get a physically smaller turbo that’ll max out around 4,000 rpm in order to reduce lag as much as possible since this isn’t a racecar. I want it to still drive like a daily since that’s what it is. I just want neck-snapping torque down low since like i said earlier i never really take it past 3,000 anyways. I’ve also heard that 302’s have a flaw where they like to commit self forever sleep at 500 hp. So i was thinking of running relatively low boost at around 5-8 psi in order to keep from risking the motor as it is a daily and I don’t want to be rebuilding the engine every other weekend. Your thoughts on this would be greatly appreciated as I hear your a lifelong 302 enthusiast. 🙂

So what you're saying is you're never actually going to do anything?

[@greenbassboosts8872]

[@orangetruckman]

I’d enjoy an M122 blower over that M90. Yeah, I know the $$ blows it out of the running. Turbo is the all around winner in my opinion. Thank you for all your efforts sir!

[@ericwilson2585]

I'd always choose the turbo over the supercharger. Back when I was in my 20's I built myself a 85' Daytona turbo Z and I've never gotten over how engines run with turbo boost. Now that I'm 51 i want to build a V8 of some type with turbo boost, hopefully I'll be able to do it before I'm dead. It's all that I ask for.

[@Eqium]

I think everyone would have guessed what would happen the ebay turbos are cheap hp and are really entry level performance and once you have it set up putting on a pulsar s400 upgrade later is still make a great performance increase great video Richard

[@maxhorner2409]

Fuel injected turbo, carb blower. The only problem with this test is yer testin at a higher rpm than anyone will ever take off which is where ya need the torque. So down at 1500 rpm. Unless yer racing with a trailer, which I have done, no one takes off with a trailer at or above 3000. Great video and very interestin to see how much difference there is because of the power loss. Thank you.

[@midnight347]

This is the problem with this kind of test. Turbo is never going to have instant response like a blower no matter how it's sized. It will still take a second to get into boost from the time you hit the go pedal, unlike the blower. The exhaust sound is different too. Some prefer the sound with a positive displacement blower vs a turbo.

[@JacobLAChristenson]

Yes you need to run an intercooler I have a 427 sbc Dart block and I gained 90 hp it lowered the boost by 3 psi by adding an intercooler.

[@bill2178]

once your towing a laggy turbo is not as noticeable because its always spooled and you spend more time in gear so it doesn’t matter as much if its not instant imo a turbo is better for towing but im basing this on laggy diesel’s

Thanks for making this video. Hopefully this doesnt dry up the supply of cheap m90s! People like to talk bad about the m90, because a there are other ways to make more power. I chose to put one on my j series honda because the exhaust is already done for an na setup, the gen v blower was $100 from the wrecking yard, and the adapter plates are pretty easy to make. Plus the blower has separate oil so no separate lines are needed. If it was trying to go as fast as possible, sure a turbo is probably better. But for a fun street car, i bet 350 whp in a 90s civic will be pretty good.

[@michaelblacktree]

The turbo is definitely more efficient. But as Richard said, there are other considerations. For example, packaging might be a concern. Or the sound of the exhaust. Or maybe you just like the whine of a blower. Do what works for you, and ignore the naysayers.

What is the price per hp? Total system price, intake manifolds, intercoolers, exhaust tubing, wastegates, everything, for both. That is the question that will answer this for most people.

By chance did you measure fuel consumption during either test? It would be real awesome if we could see the BSFC numbers for both combos as it would show the difference in efficiency of each combo. Combo wise, the turbo doesn't light until around 4500 on the dyno. I would think that's a real good time in a car with a loose converter and some gear. The blower would be great in something that needs the torque delivery in a predictable more of everything kind of way. That would be a pretty cool streetable setup but it's not going to have the fun factor that the turbo does when it lights. On the flip side, i'd be curious how that turbo combo would act towing a trailer. It would likely spool earlier, make a bunch of cylinder pressure, and push the rod bearings out of it.

was there arcing or what at the rear left coil? intro run looking again looks like loose plastic u do not specifically say blower in your graphs they look like na

I would take the turbo you still have to buy the Holley intake which make the cost much higher the turbo is the winner

I wonder how much boost can the m90 produce on a 2 litre diesel.

[@richardholdener1727]

what na power?

[@CrAzYDr1veR]

turbodiesel but m90 instead of turbo

[@azlandpilotcar4450]

Why not both?

[@richardholdener1727]

we did that on the 3800 v6

[@kalebbrown93]

Blower. How much boost does that turbo make when it's not WOT. Blower every time even when not thinking about towing.

[@richardholdener1727]

both can make boost at part throttle

[@joshjammer5716]

I’m shock you don’t have a LSA blower laying around.

[@richardholdener1727]

never had one

[@joshjammer5716]

@@richardholdener1727 I think a lsa blower would be sweet for testing like you do.

Cleetus Mcfarland took off twin turbos from his coyote to go with a whipple charger instead. Too much lag trying to make 1000hp from a small motor on the street.

[@richardholdener1727]

very easy to make 1000 hp with a Coyote with turbos and minimal lag

@@richardholdener1727 Maybe he just had the wrong combination idk

Thanks!

1:00 bad wires arcing?

nope-that is a piece of paper (wiring tag)

Richard: You do realize at this point, you're gonna hafta do a "Big Bang Boost" build on this engine (Turbo & blower, each with an intercooler, respectively)...right?😁

[@richardholdener1727]

the M90 won't make enough power to hurt the motor
