Supercharger....which one?

its worse than you think.

Please expound on this topic.

That's kinda why i want the ESS lol. I like that below 4k it just drives like it does now. Its my daily driver so its cool there's something that runs like stock when im just driving to work but runs like a GT500 when i wanna play lol. Different strokes i guess.

Honestly all of these drive like stock with a decent tune and low throttle angles. Except since you need RPM to create boost with a centric it should be almost identical to stock except at the lowest of RPM.

I don't feel any difference puttering around town at those speeds on normal mode... More than 20% throttle at any speed will start to bring me into boost. That's a significant difference when doing a comparison.

Centris are perfect for the 10R80

Yeah, I'm not convinced of that. It's all in the setup. My 3.0 makes over 620 rwtq (and 16 lbs) at 2850 rpm and makes almost 900 rwtq at peak (at 19 lbs). I'm skeptical a smaller PD blower would make more than that, and roots rotors vs twin screw at that.

At the lower power levels, the differences are not meaningful, but the idea that a smaller blower would make more power or torque is a bit of rose glasses/myth I think. The TVS may "SEEM" to punch more but that's probably because it falls off more up top.

Rotor design gets a vote, but it's a stretch to think that a smaller displacement would make more steam anywhere when given apples/apples comparison.

I mean, for max boost comparison, the more used street TQ curve could be compared. If I had mine pullied

So with the G3X the boost doesn’t come on until north of 4K rpm? This is the stuff I’m trying to figure out, with the lack of torque from these coyotes I want as much tq down low as I can get, same as you will just be a fun street car

4K? Nah. 5300+ is where it starts huffing good. 4K is is similar to centri on a Coyote. Almost stock.

Bingo. 10R80+centri (14psi+)+a sticky tire= Badass.

Ok I’ll say it again. I ran Centris for 26 years. This build, I decided to try a TVS. I’ll never go back. My car is 88.61% driven on the street.

Disclaimer*. If I had a 10R80, I would consider a centri again…….

It's where you can feel it sorta kicking in, it doesnt pin you in your seat till higher. I thought the "x" may spool faster.
With the Harrop by 3krpm im pinned into my seat.

Everyone goes on about how the ESS drives like stock, I had mine remote tune by Wengerd here in New Zealand so It was a good tune but in all honesty I think my Harrop drives more stock than the ESS, I can drive it around town and passengers wont know its got a blower until I put my foot. The only difference is im not waiting for boost to kick in with my exhaust screaming at 4-5krpm before I have fun.

This!!! after driving turbo cars, and having mine with an ESS centri. I will never got back from a TVS.

If you're in a gen 3 and don't plan on revving the piss out of the car, tvs is a good bet for 95% of these types of applications.

I haz several questions. 1) Are these two runs two different blowers? Cause the only way to back up that claim would be to install the two different blower systems and run the same pulley on them and see the curve each one creates. This appears to me to simply be the same blower on two different pulls. There's nothing here to methodically prove or suggest that the 3.0 wouldn't make those same torque values in the lower rpm range

Just take a look at any Dyno sheet from a Whipple gen 5 on a gen 3 coyote. There are tons on them out there.

Generally speaking, you will get a spike in torque and a flat line all the way across on torque with the whipple. The hp will keep rising like a centi. Typically, these tq figures are in the 500s. I mostly see something in the 53x range.

A 3.25" pulley on the Edelbrock tvs is 11# on a stock crank damper. Also when dropping sizes ~1# is .25" so it takes a bigger drop to get the same boost as a Whipple when going up in boost. The smallest you can put on a 6 rib and run consistently is a 2.75" which is ~14#

My graph is a bit atypical because of the meth,tb, and airbox kit. But you can see right away you get 400 lb-ft, pretty much off idle with a huge swell in the midrange. Whipple does not shine as bright down at those RPMs just like the TVS does not shine on the top end.

On my graph, notice that the car is in overrev when it was shut down. The torque in down in the 400s but the drop off on the hp isn't much from peak. It's not accelerating as hard. Here a Whipple would continue to accelerate because there is no torque drop off, just more HP with rpm.

I'm not saying it can't make the same torque, the boost level would be drastically different from the two blowers to match torque figures.

Edit
Yours makes 620 tq at 16 lbs of boost
Mine mars 605-610 at 11 lbs of boost.

But again, you're comparing apples and oranges. Most of those dyno sheets are 3.875 pulley.

Pulley for pulley, the Whipple makes just as much torque down low.

What is the boost level for 3.875 pulley with a stock crank damper?

Edit:. We aren't comparing pulleys we are comparing boost levels... That's like saying we comparing a single turbo vs twin turbos one @11# and one @16#.... It's the boost levels that need to be the same screw the pulleys.

 

[illtal]

I'll save us the trouble. Here's the chart.

 

[illtal]

So a Whipple gen5 with a 3.25" can be up to 16 pounds of boost with a stock crank damper.

That's drastically different than 11# with a 3.25 pulley.

Boost for boost is a much more problematic test and you know it. There's way too much error in measurement and approach. Again, I've seen NOTHING from a scientific or engineering perspective that would suggest that a 3 liter PD blower (of any type) would produce less torque than a 2.65 liter PD blower (of any type) at the same boost levels.

Y'all just need to switch to turbos and quit worrying about who has the bigger blower!

Well sounds like it’s back to the drawing board for me lol
