red bullet for the 5th gen prius

Waste of money, and it's been proven by dyno testing. The computer commands the oil control solenoid. The aftermarket ones aren't any better at doing the job than the stock ones

 

Not to mention that the M20A doesn't use an oil solenoid for the intake cam timing. The variable intake cam is governed by an electric motor. The exhaust cam is still governed by an oil solenoid. I'm in the "it's snake oil" camp.

 

Where is this dyno test you speak of?

No links to back up your statement?

Have you tried one of these yourself?

Made my Prius a little quicker.

Use promo code "azusa" to save $$$

 

Yes for best results it is best to use the car in normal or power modes.

 

Made your gen3 a little quicker or made your gen5 a little quicker? The gen5 M20A uses a completely different solenoid setup than the 2ZR.

 

Yes my old 2010 but you either can speculate or know by actually using one.

 

So far our shop (Hybridpit) has sold 3 so far of the Quantum version. It’s a tough sell because some people thinks it’s not worth it …cough cough

If anyone is interested we have a loaner program in which you can try the solenoid for 1 week. If you don’t like it send it back and get your money back.

If you are willing to step up to the plate we have a loaner program Takes about 5 minutes to install.


iPhone ?

 

Hard pass on both accounts.

Spend your money however you want. I'm sure you'll sell a few more to those who don't know better. I guess grifting isn't illegal after all.

 

I have been on Prius Chat way too long to be scamming people. Let’s just leave it there. Have a blessed day to you and your Family

BTW- Your GEN 5 looks great! Keep up the good work!

 

Not accusing you of scamming, you're just a middle man. (reseller) I appreciate the service.

Red bullet, Quantum etc are the real scammers here, just see the malarkey in their marketing. It's pretty entertaining actually.

 

I am very sad to say that you are wrong with the Good folks that run Quantum Solenoid.

During the early development of that Company they used cars from our Shop to test out their solenoids.

Honestly after that test drive around the shop you can visibly see a smile on their face when they get back!

Now they are on another level with the Japanese market which says something about their Solenoids.

I don’t have a horse in the race but just sharing what I have experienced

 

Again to each his own. The facts are clear to me, and I'm done here.

 

Quantum Solenoid for Toyota Prius 2023-2025

 

7hp.. where are we going to put all of that HP? Sure wish I had access locally to a dyno. I'd put these to the test.

************************************************
My personal thoughts on this subject....

Coming from an engineering perspective and previous experience in the forced induction world, if we look at a solenoid and how it operates, for the engine to go WOT, the cam timing can only be adjusted so far forward before you have knock.

A solenoid that makes a cam move is restricted by detonation. Sure, maybe they trick the ECM into opening it more (earlier) but that's what cam and crank sensors are for. These sensors will tell the ECM exactly where the engine is in its rotation. The engine then takes the throttle position sensor callout and adjusts to a specific amount of fuel at the precise timing to avoid premature detonation or lack of detonation.

With that said, I cannot see the engineering behind it that would actually allow proper HP gains aside from tricking the ECM and actually opening sooner to advance timing earlier than the stock solenoid. Sure, you may gain a few degrees of timing but that's not much. Butt dyno?

Correct me if I'm wrong.... but I have two towers in Manhattan I'd like to sell..

Before I would put this in my car or recommend them in anyones car I'd have to have some real in depth discussions about how this solenoid which is PWM and doesn't rely on two way communications with the ECM can make such gains. If the ECM calls out 1.5* of advanced timing and the solenoid provides 2.75*, this will set a check engine light.

Nope, not buying it based on my understanding of mechanical systems in vehicles. 100%, not your average Prius driver.

 

Yeah, kind of a key question. As the only thing this mod changes is the solenoid—there is nothing fancier being done, like spoofing the cam position sensor feedback to the ECM—we should all be able to agree that when the ECM decides to change the intake valve timing from X° to Y°, the cam timing is going to end up right at Y°, no matter which solenoid is installed.

The only difference that ever has been plausibly claimed for these solenoid mods is that the change from X° to Y° may happen faster. So let's say with the stock solenoid the advance takes 0.25 second to change from X° to Y°, and with the elite solenoid that happens in 0.15 second. At the end of that period the engine is running just the same in both cases; the elite solenoid just got there 0.10 second sooner.

Giving the maximum possible credit to the claims, let's say that means the engine output during that 0.1 second was 7 HP more. That's not nothing—but usually when you say to someone "this doodad will give you 7 more HP out of your engine", they aren't expecting you to mean "for 0.1 second at a time".

Of course, the timings above were just made up by me. I don't know what the degrees-per-second slew rate is with the stock solenoid, and I don't know how much faster, if at all, it is with the elite solenoid. Given that changing that slew rate is literally the only effect the changed solenoid can be claimed to have, you might think the promoters would be falling all over themselves to publish what those numbers are. I haven't seen that, though.
