[@Westhelockpicker]

I installed the vortech supercharger on my 99 gt with a bunch of other mods and I was very happy with it! After a little while I went to a 3.33 pulley and 42 lb injectors and it went from about 8 lbs to 12 lbs of boost but racing is a bad addiction because no matter how fast your car is you always want it to be faster. I was so happy when I was running 13s with just a few bolt ons then I was happy when I broke into the 12s and then I was happy when I broke into the 11s..... you get the point, it's never enough

[@tedjones-ho2zk]

The vortech would be good on a stroker motor since it would already have good low end torque, Root style on a small cuin motor to make up for the lower torque curve.

What if the vehicle already has traction issues? Something to think about.

[@logut80]

​@DillonAuto then you need to upgrade your suspension

[@fordmuscle73]

Yes and no, in a street car the linear power curve of the centrifugal is actually really nice in terms of giving you nice usable power delivery, and the way that blower just keeps on building as the revs increase is actually very potent when racing, especially from a roll

Kenne Bell for drag. NA for daily or rally. Vortech for anything else. That rising torque curve would hook up so good coming out of a tight corner on the touge. Unwind the steering as the revs rise and just slingshot out of there. Superbikes do that all the time - use the lack of low-end to gain control on the side of the tire and then ride the wave as you straighten out. That kind of thing becomes important with 600+ hp and RWD. A PD blower or pair of turbos could really blow the tires off at the apex.

Centrifugal blowers are way more drivetrain friendly. Twin screws give you all that low end but tear things up so much faster. Throw a set of gears in the back and just get to that power band a little faster!

[@scotttimpany2845]

Kenne Bell torque curve is flatter than flat! Impressive!

[@EffequalsMA]

Twin screw rules....from someone who's used em all. I have direct comparison on two S197s with Coyote. The VorPax was great to install but, the car felt like a slightly soggy stocker running around and you needed to wring its neck to get anything out of it. The 2.3 TVS on a mild tune just rips everywhere and helps cut the 60 foot at the track, too. Just gotta mind keeping it cool between runs. That installation was WAY more complex than VorPax, to be honest. I'd add I chased false knock for a good while tuning the VorPax, no such issues with the TVS. I'll also add that the 2.3 TVS adds more weight to the car but, makes more than enough to compensate, My loaded automatic 2014 weighs in at just under 4000 pounds with me in it and a tank of gas. runs 121 mph in the 1/4 on 8 pounds boost. Obviously not tuned max but, runs pump 91 no problem and is lots of fun.

[@JDWard-Jeepster]

A blower that comes on with boost at the top end would make it easier to launch. You also tend to suprize the competition coming up on them at end of the run. On the street the screw type just sounds cooler and a harder launch looks impressive.

[@sherylellingson3538]

Very true. Stickier tires alleviate that problem.

I had subframe connectors and a lot of maximum Motorsports H&R and tokico suspension parts, and 03 Cobra Brakes. 450 rear wheel doesn’t sound like a lot, but when you can rip around the streets on a car that stops and turns on a dime much more power wouldn’t have helped the car…. It never broke, EVER!! I could drive thousands of miles at a time with the AC blowing and it would run and drive like stock. On that note, I’d try the Kenny Bell to replace that junk plastic intake and to keep the battery under the hood.

[@gruzzy89]

Twin screw for good short track times on drag car with prep surface. Vortec street car possibly less likely to brake traction on the low end, maybe a slightly better mpg when not on full throttle.

[@cesarpalmos8235]

I have a thick Crown Vic with a very healthy 2v at 79k original miles. I was planning on using it to build a 600hp - 800hp setup. The KB would be nice for low end torque, but the VT seems to be able to produce more peak hp. If I'm being honest, I get goofy over that KB whine.

[@commonsenseisdeadandgone]

PD blower hands down on a street car, ESPECIALLY with a heavy basterd like a Vic! Also taller gears help get the two and half tons of fun out of the gate a bit better! (I have a Vic with 4.10s and a manual trans.... Faster with the auto but so much more fun with the stick! .... I have a KB kit and other goodies sitting around for it but current project is the suspension and audio portion 😏)

[@commonsenseisdeadandgone]

Oh and it really doesn't matter how healthy the current engine is, when you're looking at 600+ hp then you need to build a lower end anyway! Also the KB also takes care of the intake manifold issue with 2v's when looking at that power level considering there isn't much out there and what is, is ridiculously priced! Then comes the heads which honestly if you want to keep it "budget" then rods and pistons, 4v head swap and turbo would be the way to go! Then your limiting factor becomes the transmission! 600+ HP isn't as cheap as people seem to think, just in hardware I had over a grand alone! It is much cheaper nowadays with the flood of Chinese products being readily available (for instance turbos, an line and fittings, tools to fabricate, etc...... )

[@CLEEPER1]

[@sherylellingson3538]

Kenne Bell all the way. The lower HP and torque at the higher RPM's is worth the difference on the bottom end. I have an Edelbrock E-Force on my 3V Mustang, and love the instance torque when I stab the throttle. It doesn't matter what RPM you happen to have the motor at, it always happens.

Really depends I’m usually deciding on how to build power while considering the purpose of the build. A lot depends like the rest of car combo but let’s give it a shot. Street- screw blower, man trans, 3.55:1’s Track- centri, auto 3 spd,5000 rpm stall, 4.11:1-4.56 I still like the screw the truck would only win at the track maybe. There’s actually a huge Disparity in the power in the screw blowers favor even though the centri peaks higher. If they were both e85 (pump gas) then the screw would probably be safe on even real hot days. It’s very hard to beat the screw blower on this one.

[@commonsenseisdeadandgone]

For the track a centrifugal makes the most sense because you're gearing the car to stay in the higher (peak) power band. Either way, Vortech and KB really are street use brands.

[@bfrmotorsports6297]

Great video boss! I want a Kenne Bell next year for sure! Gotta get the cams and heads and long tubes first. Thanks for the video!

[@DragonFireEngneering]

The twin screw operates kind of like turbo with electronic boost control and the huge difference in area under the curves is hard to ignore. It will not make as much power as turbo with same boost due to supercharge losses but it is a really good choice when under hood packaging is a factor. For every day driving, I have always liked centrifugal and roots style superchargers. It is not easy to put an instant 500lb/ft of torque to the ground. T-5s will also hold up under that level power (in daily driving) behind a centirfugal or roots supercharger but kind of sketchy with a turbo or Kenne Bell.

[@commonsenseisdeadandgone]

Think that's the first time I've heard a PD blower operates like a turbo (considering a centrifugal is literally a belt driven turbo....) "It will not make as much power... with the same boost" That's not how it works! It's also too vague. You say that it will hold up to a "roots" but not a "Kenne Bell"? Roots is a PD supercharger just the same as a KB..... Also a PD supercharger is harder on a transmissions than turbo for sure!

[@seanadams8444]

Another killer video! Really appreciate the time spent on the camshaft comparisons too. Especially on these motors -- double the aggravation. Lol

[@allandriver2066]

I'd go the KB every day. It drops the torque in the sweet spot. 👍🇭🇲

[@hotrodlincoln7186]

I would say at first I'd go with the kennebell. But, more than likely, I'd go with the vortech. For a few reasons. 1. Like you mentioned, the traction. You see all that tq is going to be putting alot of abuse on your rear-end. Plus, not only that, if you don't have traction, you ain't going no were. 2. Vortech tends not to overheat as much as a kenne bell would. 3. Unless it's going to be a track only car, then yea the kenne all day. But, if it's a daily, then the vortech is better. It's better because you can have just a regular car when just daily driving it normally, but when you want that power, it's there. 4. The amount of gas you're going to be spending with a kennebell supercharger. I've seen some videos on here where you will only be getting 8mpg 10mpg if you baby it. You see with a vortech supercharger as long as you drive normal it's never in boost, and if it's not in boost, then it's not being so hard on your gas. 5. Oh, and for all those that say well the vortech takes longer to rev up in rpms. Well, I got something for that. It's called jmschip by pedalmax. The jmschip does not mess with any tunes, nor is a tune required. Basically, what it does is depending on how you have the dial set on. But like with me, I tend to have mine between 75% and 100%, and man, you barely have to tap the gas, and it just goes. It even down shifts easily even if you're already doing like 75mph. Just look at my videos and see for yourself. Oh by the way the website is called www.Jmschip.com Just sure you choose the pedalmax option as they have many options.

[@RepoDraghon]

In this case, Kenne Belle street car but there are versions of that that essentially push so much air that you're basically making a V8 into a V8 with a V8 on top... It also depends on whether you drag race from a dig or drag race at like 60 miles an hour...

[@mikesmith1550]

I had an 02 gt with ported trickflow heads, comp stage 2 cams(don't ask me specs because I have no idea anymore), jessel folowers (those mf'rs were like $100 each) BBK long tubes, dual gt supercharger pumps, and a vortech v2 with a billet impeller upgrade made by some company (supposedly when spun harder would outflow a t trim) even after I put the nitto drag radials on I barely got traction after I heatedthe tires up. I can only imagine how terrible it would have been with the Kenne Belle with all the extra low speed torque. The centrifugal setup is definitely the way to go. All the horsepower in the world does you no good if you can't transplant it to the ground.

That low end torque on a street strip car would eat the Vortec for lunch, especially in a light to light scenario, or 1/8th mile.

@@sherylellingson3538 on the big bore 2.1 and up, you don't get the whine like the (terminators) unless you're closer to 20lbs. You get a little noise but barely

@@sherylellingson3538 the new kenne bell twin screw has eliminated that whinning sound now.

@@berardoferrariidk what you guys are talking about because i have a new 2.1 kenne bell on my stock 4.6 only making 9 pounds of boost and its really loud. If run a short ram intake with a 90mm maf and a 75mm throttle body the sound is perfect. Ill upload a video from a 2k to a 4500k pull

Wonder why I can't comment or even see live chat? Wanted to ask you about what size turbos do you think a pretty much stock 500 cadillac would take? After I add ring gap of course. It will have a pretty small cam but larger than stock I plan to get from cmd.

[@richardholdener1727]

WHAT HP LEVEL?

[@barenecessitiesJL]

Centrifugal with my 12.3 CR

[@TurboTurdBurglar]

i personally love the kenne bell for a street car. but if i feel like the vortech would be better for racing

[@gregmckinney6977]

KB for street and the Vortec for the strip.

[@keithsmith9889]

I'm not really in a place to test and know but about ten years back everyone started making intakes black cause they claimed it disappated heat better. So I can't help but wonder if you black engine enameled all the cold side of the turbo system would it make a measurable difference. And I get it would make a mess. But if you're curious also I would like to see it.

[@richardholdener1727]

no on the black paint

[@Jim_Lawrence]

Twin screw for street 💯 For track, I don't think I'd run a 4.6?

[@P71ScrewHead]

The 4.6L is respected at the track, even seen one 2v kicking big block car's asses in Street Outlawz a week or two ago..

[@Jim_Lawrence]

@TigreLoko24 I didn't say you can't clean house at the track with a 4.6, I just wouldn't choose one. BBF, turbo 9.5 deck or Coyote would be chosen first.

[@P71ScrewHead]

@@Jim_Lawrence Not bad at all, I'm a big block person myself.. Nothing like having huge amounts of torque from idle to wild, as I like to say..lol

[@Jim_Lawrence]

@@P71ScrewHead 100% That's actually why I daily a diesel. Torque junkie...

[@P71ScrewHead]

@@Jim_Lawrence Amen to that.. Besides displacement, there's no replacement for torque..

[@USARAY1947]

Why use a Vortech when a turbo will have the same shape power curve without the parasitic loss. I'll take the instant torque all day long from the supercharger.

[@01Snorky]

Because the vortech is a cheaper, easier set it and forget it setup.

[@nitro1271]

What size injectors do I need for a 1000 horsepower on 06 4.8, and who makes a reliable injector?

[@richardholdener1727]

80 pounds will just get you there on gas, you need 100+ pounders for e85

[@wb5mgr]

I can tell you as someone who does road racing that I run a harrop TVS 2650 with integral intercooler. While this is very similar to the Kenne Bell I find it superior because if the integral air to water intercooler that I don’t believe the KB has. I would rather for my application have a unit like this all day long as the vortec Will never see 6-8000 RPMs except on the back straight and then only for maybe for 20 seconds. However it lives its life below 4k most if the time where this unit shines. Hell my engine redlines at 6800 so not much room for me to take advantage anyway.

[@richardholdener1727]

the Kenne Bell has an ATW cooler-and Twin Screw is more efficient than TVS Roots, but the 2650 works well

[@rogerstill719]

I would HAVE to run a turbo and really turn it up

[@creverett9]

yes big bang 2v!!!! lets do it!!!

Let's do it then!! I'm actually attempting to do that on my 09 P71..

I'm still waiting for roots blower with a clutch like Mad Max had...

[@andyharman3022]

That's been done. The Mercedes M271 had an electromagnetic clutch to stop the Eaton blower from turning when boost was not demanded. Plus, the Eaton blower had a bypass valve.

[@davidmitchell7183]

@@andyharman3022 Not sure it's trivial for a electro clutch to hold an over 100hp load?

[@TheInsaneShecklador]

The Mercedes 55 AMGs have a clutched pulley but I guess technically that doesn't count because they are twin screw and not roots.

[@davidmitchell7183]

@@TheInsaneShecklador I went down the "rabbit hole" before searching for higher power electro clutches before and couldn't find much. Let me know if you figure it out. Would be ultimate cool with on demand supercharging and bypass.
