I love these comparisons with detailed explanations. I have a book you wrote about building sbf motors with supercharger/combos " dyno proven 5.0 " from 2000. Still read through it when I'm in the garage!!

In the drag racing world, the shape of the power curve means almost nothing with a torque converter that keeps the motor in a 500-1000 rpm range for the entire run.

@@justinward5928 if I understand your question correctly, you're thinking of stock style torque converters that couple around 1500-2000 rpm. Performance/racing torque converters will move that up significantly. In a drag car, the conveyor will couple at near peak power at full throttle i.e. 5k+ rpm. This is too much of a compromise though for part throttle driving where the car will feel unresponsive and sluggish at low throttle because the engine will need more throttle input and more rpm to create the same change in vehicle speed.

Yeah I see the supercharger giving a linear power curve and the turbo just overwhelms the chassis; sometimes less is more.

best explanation this far! Thanks man.

Gearing, Transmission choice and proper setup can go a long way to level the playing field and even help the Supercharger to shine. Let's say for instance that 2 cars weigh the same, same rear tire, one is Procharger and the other is Turbo charged. In this example, the Turbo car runs a 4.11:1 with a Powerglide and perhaps 3500 stall. The Procharger car needs only run something like 4.56:1 and a Turbo400 with 4000 stall to make the most of it's powerband. This will make sense to those that understand each setup. These values mean nothing......ONLY WHEN COMPARED TO EACH OTHER FOR REFERENCE. Just an off-the-cuff example. Be nice. ;)

It all depends on where you're racing. Are u racing on the highway? Or are u racing on winding S shaped roads? Lots of left and right turns etc. One setup will prevail over another.

I’ve only had one boosted car, and that was an ‘86 svo. I knew the dealer back then and he had the wastegate adjusted to 18 psi. That was one quick fox body. In stock trim it has basically the same hp rating as the GT, but only 240 torque. The 5.5 extra lbs of boost made a huge difference. That torque would really set ya back in the seat.

Appreciate the breakdown

That 21psi boost curve is nuts for analog control. That's also pretty good response for two pretty big turbos on a pretty small engine.

PIN IT AND BE DONE

It all depends on the build , how the parts are speced and weight of the car and set up. I run a 416 with a Ysi race centrifugal blower and it’s not laggy at at. Power comes in at 2500 but I don’t see it because my stall flashes to 3500 rpm where my cam and blower all start to really come on . Proper specing of parts and how they work together is more important than just trying to make the most power. I’ve dog walked plenty of turbo 5.0, Camaros , gtr’s and civics most making more power than me because the 416 on motor makes plenty of tq to move the car and once the boost comes in it’s like nitrous that carries to 7500 rpm with a flat tq curves. I make almost equal tq to hp which is only seen in roots and turbo cars . Turbos are nice but I like my instant power , no lag , low heat , easy set up , easy to hook up but violent power delivery , predictable non on off switch power delivery and outside of you wanting to make promod power they can make just as must as turbos and on the same psi I make just as much power as some twin turbo cars but I think the Intake and cid heads play a big part in the efficiency.

Actually a smaller procharger, I run a -94 and it's very peaky...in fact there is something not discussed at all here, the -94 can drop 5-6 psi on the shift its so peaky... The M3SC marine I ran on my car come on boost and held it like a PD blower... For this test since he stopped at 6300 on the turbo or less and two of them... Might have been fun to see the twin torque storm curve their impeller comes on quicker... 2. A P1X or D1x turned near its max rated impeller speed would have drastically improved that soft hit on the -94s rising curve it would have been WAY closer...then dump out the peak in the same way you did with the turbos a waste gate, I have 2 Vbands in my charge pipe just for this...then you can also get a DS Delta and change tune ect ect for TC.... I get we are showing the difference but efficient twins vs a peaky -94 impeller running below its compressor map speed with that 4.25 pulley isn't a remotely close comparison... You can make a smaller p1x/d1x hit really hard spun to their max impeller speeds or you can do it with the -95 say in this test even a 3.85 pulley stopped at 6300 or with a waste gate would be a lot closer..... That said it looks like the -94 uses a little over 120hp to make 500 net...well that's actually great considering an F2 required a cog and would take 2.5x that... Ironically I run a F1A-94 with a BBC using a short stroke literally to do what he said let the chassis work a bit in the old 67 Camaro on a drag radial..... Interesting....thanks as usual

The one that works best depends on your situation. If all you want is to make power and spare no expense then a turbo is for you. If you want to have a linear power band without sacrificing exhaust tone but dont mind that it doesnt nearly blow your engine up at max boost then a procharger is for you (I may be biased)

2nd time watching video. I thought about it more. I agree turbos spinning that type of power would be very bad to drive in the street.

It really depends on budget. Abbilty to do the job . Your engine you are building or already have . One robbs alot of hp from the pullies and rev much higher . The other has 2 turbo and runs much more efficient but cost more to build.

Turbos cost more and are more difficult to install.. you will deal with oiling issues and have to worry about overboosting... they make the most power... if you want xxx power without the headaches then a supercharger is the way to go.. just know its less efficient and puts way more strain on your engine and its bearings.

I think a big thing is also the turbo lag and not so much nowadays with electronics throttle body's but still depending on tuning, the handling of the power. Let's say you're on the corner getting on the power, the car can handle 30% of the power @your rpm when the turbo is not making boots, now the turbo is "creating" on boots and you have even more power you need to trotle down, in a perfect world you need to lift the trotle just the right amount when the bost is coming oon to maintain the manifold vacuum constant, but it's really hard to doo, lift little too much and the turbo is stopping boost, don't lift enough and the turbo will make ewen more boost in till it reaches the gate pressure. A supercharger takes all this away, jeah you still might have a really small window to play with in in the pedal, but when you find it, it's there and are little more stable. You can find this even with small engines, small power outputs driving on ice or snow, it's like having 5x more power than you can put down even wit 100 to 200hp and then you have your turbo wanting to kill you in every corner ewen when na power is all too much. Don't get me wrong, it's a lot off fun, it's just impossible to run some kind of good time All the best and keep up the good work 👍

Hah! I feel for ya. I have two turbo cars. One is easy to drive off the corners with the power on, and one isn't. The one that is easy (3.5L V8) has 2 small, factory T25 turbos, and a rising rate throttle linkage. The boost control is electronic and has throttle position as one of its inputs. The hard car to drive (2.2L I4) has a single aftermarket hybrid T4 turbo, that is a bit laggier. The intake has individual butterflys for each runner, and has a direct non-rising rate linkage. The boost control has inputs for throttle position as well. -- I would say that having only enough turbo to get the job done is very important. A compressor map to select the turbo is a must. Get a wastegate controller that has throttle position programming available. This may be your lifesaver. Consider a rising rate throttle linkage. Certainly drive out of the corner with the turbo in mind, accounting for maybe a 1/2 to 1 second lag time. I have no advice for wet roads........since my cars are mid-engine and scare the shit out of me when they cut loose under power. Cheers 😜

Do you have EGT or fuel consumption figures from these tests? I’d like to see the torque when the F1 is making 21 pounds at 6300 RPM

Even in Street Outlaws NPK almost every single person in the top ten in points up to this point has a Hemi with a Procharger on it with the exception of a one big cubic inch nitrous engine and maybe a Hemi with a turbo or turbos on it and a 481x with a turbo or turbos on it

There happens to be 3 nitrous cais nitrous cars in the top at NPK and they all went to the hemi pro charger because of the weight brake

Change your gear pulley on your centrifugal to match the boost peak at the identical rpm. Then add a wastegate (or two) on the intake and an electric clutch on the centrifugal. Now the turbo is pointless. Better yet twin charge it have a bypass air tight throttlebody that is boost relay activated or a spring loaded sealed flap so you can spool up your bigger turbo quicker with the smaller 1000hp centrifugal. Then add nitrous.

you can't change pulleys to get the centrifugal to make max boost at lower engine speeds. Only an electric motor can spin it up to max speed-complex and expensive-just get a turbo if you want what a turbo does.

Would be great to compare the two chargers on the same motor Yes extra work and money But it’s a much more useful experiment

My concern would be there would be too much Boost at high RPMs but obviously if your Fuel System and Engine is rated to handle it, in theory it would be okay and sustainable? and what about intercooler plumbing for a Centri+Turbo

Despite dyno limitations, pulls from idle dont make sense in the real world. If you have an automatic, its going to downshift and the converter is going to flash to stall speed. If you have a manual and youre making pulls from idle in high gear... You probably don't like your motor very much.

High end rpm of boost is salvageable. Drag racers do it all day. It’s called a scrambler. They just close the waste gate and blow off. To use the spare boost they otherwise would be blowing out.

Not quite.. scramble boost is a 2nd boost level setting, usually triggered by a button press.. yes it effects when the wastegates open/how much.. the bov always stays closed under boost regardless..

Hello Richard, I really enjoyed this test & video, so much so that I just had to make a comment. When you displayed the output from the engine fitted with the Procharger, I thought that the torque curve (& curve is a relative term in this case) seemed very bad - the RPM at the HP & torque peaks looked very close. I figured out that the torque rose the way it did because the boost output was a function of engine RPM, not exhaust output. But, I also thought that choosing a gear ratio spread for that engine would be very difficult, as most options would give weaker acceleration at upshifts. It wasn't until you mentioned the drag racing situation where it all became very clear. Since most cars raced with a Procharger are fitted with either a direct drive, or a 2-speed transmission, the RPM drop calculations for gearing is mostly irrelevant. That was the bit that I enjoyed. So, thanks for the test & video. Now, I'd really like to see how a roots supercharger compares to the Procharger & turbo combinations. Anyhow, keep up the good work. Thanks. :)
