I give you 10k for supercharger , which one are you picking and why? 🧐

[JoeCee]

Thanks Dad, I totally forgot that you are the Forum Police, and the Premiere ESS Fanboi.

I'll go ahead and respond to any thread in exactly the way I see fit, and just like you said that he is not "required" to provide context, nor am I "required" to provide the response that you like to hear. If my opinion is that a budget turbo system is better than a $10,000 Supercharger setup, then that is what it is. He can take it or leave it. I wasn't even responding anymore until Nathan wanted to point out that OP said "supercharger", like I didn't understand the assignment.

Low boost "budget" Centri systems are disappointing at best. These things really only drive they way people expect them to, when you pulley way down, and then are forced to run E85 and the supporting mods to get there.

Why are low boost Centris a disappointment?

Why are low boost Centris a disappointment?

Because they don't make any appreciable amount of torque over stock until you are way up in the rev range. 6psi from a Whipple is going to feel a lot more powerful than 6 psi from a Centri, because you don't get that 6 psi from the centri until redline, whereas the 6 psi from a Whipple (or Turbos) is available almost instantly.

The Centrifugal setups really only wake up, when you pulley way down, which then requires E85 and the supporting mods to go with it.

This all certainly also depends on use case. If your intention is to drag race, then Horsepower is what ultimately matters. If you are just wanting a faster, more fun on the street car, then you will be disappointed with a low boost centri setup. Having to take the engine to at or near redline just to squeeze out the power means you are 1- flogging the motor and 2- probably into triple digit speeds. Turbos or a PD blower for a street car will definitely provide that feeling you want.

Don't get me wrong, a Procharger or ESS making 15+ PSI is crazy fast, and feels like it because you are getting into the boost much sooner - but aren't likely getting there under $10,000.

This is true. I've found that alot of coyote owners are scared of RPM. They don't want to rev the engine despite the fact it was designed to do so. There are advantages to every system, we have plenty of choices so that's a plus.

I like my 8ish lbs from my centri! As a daily I have put a little over 18,000 miles on it since September. I notice a good bit of difference above 3000-3500 rpm. But, alas I do want E and to pulley down. LOL I'm used to it, but I took a couple of buddies for a ride this weekend and they were impressed. Yes, a whipple or turbo would be faster though.

So if you pulley for 8 PSI, you are probably only seeing 2-3 PSI at 3,000 RPM.

Thanks. I don’t want full rpm pull hp, and I was considering a g2 on 93. I actually saw a g2/93vs a header, intake E85 gen 3. S gen 3 street race video and it was damn close.

 

[Bob Lob Law]

A G2 on 93 is going to make 600+ to the wheels depending on the quality of the 93. I have crappy 93 in the area and I'm 600ish whp. It's a fun daily, but I like all want more.

They aren’t. Like I mentioned in response, my car on the 125mm pulley (largest pulley offered & 7-8 PSI) ran 9’s in the 1/4 mile and low 5’s 60-130. There are many on the 120mm pulley than run even faster.

That was enough power on pump gas to spin my 305/45/17 street R drag radials in 2nd gear on the street. My regular street tires didn’t stand a chance at any speed.

Anyone that thinks low boost centrifugal setups are “disappointing” typically don’t drive their car properly or don’t have it setup well. I will never understand why people are concerned with what power and TQ the car makes at 2k RPM. That’s not how you drive the car and that’s not where the powerband is for a coyote regardless of power adder. They love RPM. A simple downshift gets you to 5k RPM and boost hits immediately.

Here’s a video example of what they do when you start from a roll in the correct gear. 100% full weight S550 premium. 125mm pulley. 7-8 PSI. Never sees below 4500 RPM.

So you're running 140+ mph traps on 7-8psi?

Correct, in better DA it probably saw a touch more. But regardless on the 125mm pulley, full weight, and stock converter it ran these times. Slip and video of that slip below:

 

[robvas]

I'd like to see a mechanical boost gauge hooked up on that car at redline.

It's only getting 7200rpm right?

 

[SheepDog]

I guess some of these cars make 800+ whp on pump gas and 7 PSI.

I’ve had that car and several cars similar to it on the dyno. Based on that DA and conditions the closest dyno graph I have it made 9.2 PSI at 7,800 RPM. It’s shifting 7,700-7,800 max on that 1/4 mile pass. In worse conditions like in the summer time it will make over 1 PSI less. We range negative DA to +5,000 winter to summer. That 1/4 mile pass was about as good of DA as I ran the car in, it was around 1200 if memory serves me.
