WHAT MAKES BETTER LOW $, JUNKYARD BOOST? M90 SUPERCHARGER VS CHEAP, EBAY GT45 TURBO. RESPONSE VS HP

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!

[@alexray55]

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!

[@Sir.VicsMasher]

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.

[@michaelblacktree]

Wow, this video is chock full of good info! Just out of curiosity, will you be trying compound turbos on the 3800?

[@richardholdener1727]

I did a turbo/blower compound on the 3800 already

[@michaelblacktree]

Yeah, I saw that video. IMO it would be cool to compare / contrast that to compound turbos.

[@amandaschuch2372]

The snail duh, m90s are so inefficient

[@gforce_117]

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.

[@ericeberspacher9834]

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.

[@richardholdener1727]

it makes the blower more efficient-but dramatically raises (compounds) the boost (which raises the air temp)

[@jacobburskey3044]

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

[@NBSV1]

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.

[@reginaldoramsey8588]

YOUR THE KING 🤴 TESTING

[@JC-gw3yo]

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

[@DarkLinkAD]

Thats expected, it uses Tiny turbos.

[@Saddedude]

Tiny expensive turbos that like too pop.

[@cameronf2758]

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

[@allanb3222]

It's not his intercooler, he borrowed it.

[@brunothinkshecan7305]

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!

[@BoostedSpeedDemon]

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

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.

[@richardholdener1727]

THE TURBO GIVES THE TURBO A BIG ADVANTAGE-IT'S NOT THE COOLER

[@andyharman3022]

@@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.
