They both made the same power even though the blower made a little less boost. If there were no losses with the turbo, it should have made more power with less boost.

You can make a flat boost curve on the supercharger with a bypass valve or blow off valve.

An even smaller pulley would be needed.

Adding a Cvt might give you a little more torque but at huge complexity.

[@scotttod6954]

Cvt runs opposite of what you would want though. It starts with low gearing and runs to higher. You would want it to start high and then low to keep a flat boost pressure. It would be interesting setting up back shift and secondary ramps. Again though you would have to run inverted pulleys or something weird to get the desired effect.

Great video as always, one of the best KZbin channels hands down!

[@AlexLTDLX]

So the turbo needed more boost to hit the same hp level? The whipple hit 800 hp at 9 psi... the turbo needed 9.7 psi to do the same thing. This tells me the turbo is maxed out, but the Whipple has a lot more to give. If you pushed the whipple to 15 psi, you'd be well over 1,000hp; but the turbo might not even hit 12-14 psi. What will happen is the Whipple's boost curve will start to flatten out as you near it's maximum flow. This happens with any PD blower. The closer you are to maxing it out, the more torque you'll make at lower rpm. I think the terminator Cobra guys were the first to figure it out when they started pushing the stock Eaton blowers to the max. Don't get me wrong - I think turbos ultimately make more power, but PD blowers, particularly when they're sized properly (or even slightly undersized) are absolutely unbeatable torque monsters. Of course, the tuning window also gets smaller, but hey - there's always a tradeoff. Which is why I've swapped my Whipple (9.80's at 140 on 93 octane pump at 3,500 lbs) for an electric turbo (actually Vortech) - the electric setup offers the fun of the Whipple, but the efficiency of the turbo (actually better - zero losses anywhere) - we're seeing 32 rwhp per psi, and we're only in the 440-500 rwhp range (so far). The Whipple was less than half that much hp gain per psi.

I've been thinking out offering up my electric Vortech for you and Steve to put on an engine dyno; at this point it should be good for around 700hp and weighs about 50 lbs, battery pack included.

BTW - at this moment, not looking to market it; I'm just like you - I want to see what's possible.

[@andyharman3022]

I expected the turbo to win, but the boost curves are so different, it seems like cheating. The GT45 may be too small for this test. It's making 10 psi at low rpm, then boost falls off after 5700 rpm. The turbine must be going into choke. I have seen other Holdener turbo test video where the turbine is too big for the engine, and it provides a rising boost curve, which would make it more fair for the Whipple. On the other hand, the oversize turbo would have lower drive pressure at high rpm than the GT45 did, so it would make more peak power. I've been wanting to see a test between a Whipple and an Eaton TVS of comparable displacements on the same engine and at the same boost level. I bet the Eaton would win.

[@pwilly7]

The Eaton will Win. Whipple Can’t compete with the TVS efficiency. Maggie TVS would be best I think.

i feel like there is a little slight of hand going on here. With both the NA and Super charged set ups the dyno graph begins approximately at 2700RPM, when the Turbo enters the fight, suddenly the graph begins at 3500RPM. I know it's not much but i suspect there is some turbo lag there at the bottom of the graph which would benefit both the NA and super charged motors. If we are comparing things, the playing field needs to be flat. same motor and the graphing needs to have the same parameters. Maybe it all amounts to nothing, maybe it's all intended to drive the comments, maybe it's just an oversight but it's definitely off a little.

[@jamesbosworth4191]

Good observation; that is the big performance disadvantage of turbos - turbo lag. Not much on a diesel because diesels are unthrottled, so the "pump" of the turbo doesn't slow way way down at idle the way it does on a gasoline engine. I say a supercharger is the way to go on a gasoline engine, except for aircraft, as a plane does not idle once in the air. The engine runs at a pretty constant speed.

Richard, got a big Procharger laying around to put on a 4.8L? I've always wondered if you could get a flatter boost curve by using an oversized centrifugal supercharger and had a boost controller connected to the BOV to bleed excess boost at high RPMs. Even though it's oversized, theoretically because it's generating lower pressure, it'd wouldn't be a massive power hog vs using a smaller SC. But the bigger SC would be less efficient...hmm. It'd be a be a waste instead of using a turbo but It'd still be interesting. If anything it'd be good at blowing any leaves out from under your hood. :D

we have done that

I like how he makes it easy to understand for a young mind like mine 💪

[@jedidethfreak]

Left side guy talks a lot of shit for having a stock truck with no boost.

[@hoonaticbloggs5402]

It would be nice to know intake air temps on both combinations

[@TwoLotus2]

Yep, good point.

[@beartodrift5345]

I liked the opening arguement lol. Great comment arguments

[@trevorthomas6043]

Do you think using electric waste gate good for a street car?

[@buschlightpyro660]

Great video. What was the a/r on the turbine side of that gt45 turbo?

[@DodgyBrothersEngineering]

Why didn't you let those two guys at the beginning continue their argument, I was just going for popcorn.

[@richardholdener1727]

THEY ARE STILL FIGHTING

Twin-screw Supercharging an engine cost so much that I think many of us find turbo-charging is preferable. If the costs to fit all types of forced induction were equal, our discussions would be about how to apply each power adder to specific engine displacements and specific usage.

Outside of Top Fuel, you get a supercharger for the looks and sound these days. The performance gain is just a bonus. I don't know anyone who would build a motor for raw power with a blower, it will always be turbines. Be it exhaust run or belt driven. As for expense, if you buy 1 quality turbo its about the same. If you buy two its more expensive, but also twice as powerful again. $2500 for a blower is not that far off $1500-2000 for a quality turbo.

@@sylumgand What are you talking about? Legit turbo kits are not cheap and just as expensive as a Superchargers. You are talking $7,000-$10,000 for either kit. You don’t see big twin screws on street cars because the torque they create causes the tires to break loose. This is why you see more pro charged or turbo set ups with more aggressive street/track builds. Generally speaking Turbo’s are much easier on internal parts, transmissions, rear ends and advantages in tuning. New Whipple 3.8L is making 2500hp on Coyote and Hemi Applications with appropriate engine build to support. The old negative about superchargers 10-15yrs ago was they were extremely inefficient and didn’t make power like Turbos could. That’s now vastly changed with technology, and now you have guys running deep 8’s on truck and car applications with just mere supercharger at full factory car weight. ATI Racing was running 6.60’s with a Iron 388 and a old Gen 4.5 Whipple in a 3,000lb car. Now they moved to a Billet Block and new 3.8L with the intent to chase 5’s. That’s how far superchargers have come.

@@KTger If you are spending $7k+ on a turbo setup, you're paying for the names and labor to install it. And you cant even use the old saying "You pay for quality" because everything is shit anymore.

[@KTger]

@@sylumgand I’m not even taking about expensive competition turbos. Top of the line stuff can run you $5,000+ similar to the 98mm Pro Mod Gen2 I once had from PTE. Raw materials alone isn’t as cheap as you’re making it, whether you put it together or someone else does ( time is money, no matter how you slice it ). You also need the machinery to begin with in order to even fabricate. 🤣🤣.

[@sylumgand]

@@KTger You are talking about top of the line stuff. I have a big single(not 98mm but 76mm) rear mount. The turbo was $280, charge tubing was $150, BOV $50, fuel regulator $150, 2.5in exhaust tubing $125, didnt even bother with a wastegate so toss another $150 I have to spend, $150 for the hat to mount on my Sniper, $80 for oil lines because a hydraulic shop is nearby and its easier to have them make them for me. No where near $2000 and it runs and drives, not taking it past 8psi until I put it on a dyno and have someone who knows fueling handle it. I have more invested in the super sniper and hyperspark ignition system, than I do the turbo equipment. And I could have still done the rear mount without the fancy Holley shit.
