Full throttle Electric Supercharger Build Thread

I can't think of a situation where I'd want boost under partial throttle. Can you give me an example?

Further, the brilliance of the throttle switch is it eliminates the need for a BOV. Think about it; you're at WOT with the compressor spinning, you reduce throttle to shift, and as you pass through 3/4 throttle the compressor stops spinning (it has internal brakes...it stops). When you get back on the throttle you're at full boost again.

The simplicity of design is one of the things that makes this kit so cool (and affordable). There are hundreds of posts in this thread where people want to make it complicated. Once you have an opportunity to drive a car with it installed you'll quickly realize that does what it is designed to do, provide boost where it is needed most, when it is needed.

What other posts are just purely bad? I'm not technically sound and I knew this was like a switch based system for boost. Just thought a switch would start the charger up for passing power somewhere in the rev range without going full out...since full out stock is already not bad. It just seems like going full throttle while full throttle already isn't bad seems counter productive. I was just seeing if more power could be had just chillin on the road, press the button, make available boost, put foot down a little more, pass, let go of button, keep driving. Hope that made any sense at all. I'm on the forums for info and to voice my opinion. Sorry if that isnt up to your standards.

If the blower kicked on 80%-100% that would be great. It wasn't a bad question. If it could be tuned to the users wants needs it just makes the system better. Not everyone only wants more power at WOT.

Technically it does work at 80% physical throttle, which is 100% throttle to the ECU (Depending on where you install the pedal switch).

Boost under part throttle runs into a whole bunch of new tuning scenario's.

For what its worth the DR does boost(1psi) when you want a little more. It gives a nice bump in torque as it pulses even when at partial throttle.

Everyone wants more power at WOT!! Thats where this car really needs it.

Its already a great car for kicking around town but where it falls on its face in the mid range is where it really needs the help.

You have to remember in any FI system most of them function are either on or off as well. In my STI when driving around normal you are always in vaccum, then when you go 50% throttle it transitions out of vaccum and sits around 0psi. Now when you go from 50 to 75% throttle goes from 0 psi to 20 psi..... if you are very careful you can hold it in between but once your revs are up it just wants to go.... thats how turbo's work.

Sorry if this doesnt make sense its early in the morning still Main point is the system in its current configuration just makes sense.... once more people drive the system it becomes more clear.

Initially i was the only one defending it but now with 8 testers they all agree it isnt weird or abrasive in the way the boost comes on.

Yeah, I didn't even think of that can of worms.

Whenever I find myself wanting more power, I just go WOT. We're only talking about 2-1/2 inches of total throttle movement here folks. It's not in anyway inconvenient to add an inch of throttle when you want power.

I kind-of see what you're getting at - for instance if you're driving a turbo car, you move the throttle a little and wait for the turbo to surge, so you get to passing speeds without pinning the throttle to the floor.

This system is pretty linear - on a stock car you're at 100% throttle way before your pedal is pinned to the floor. Think of it this way:

Pedal 15% to floor, throttle 25%
Pedal 30% to floor, throttle 50%
Pedal 45% to floor, throttle 75%
Pedal 60% to floor, throttle 100%

With the ESC you then have
Pedal 100% to floor, throttle 100% plus ESC

So think if it this way, the ESC just gives you more power in that last bit of pedal travel that you didn't have before. Instead of fiddling with a button on your dash, just move the pedal further if you need it. Simple.

Disclaimer: the pedal to throttle relations were just pulled out of my ass, I have no idea what the stock mappings are, and I know they can be changed by a tuner. Just using easy numbers to illustrate the point.

How does 1 go about testing this system? If its what its developing out to be, they can take my money lol.

[CajunFRS]

I bet they need some testing in this good ol Louisiana humidity.

:P

No dyno test today. Auto shop teacher forgot the laptop. Will hopefully test tomorrow.

There is definitely a benefit to partial throttle power, but not for this reason. If you're trying to pass someone and you need the extra power of the ESC, you should be going full throttle anyways.

The scenario where you'd want the additional power during partial throttle would be during cornering, where you're modulating the throttle to maintain proper balance/etc. However, in these situations though, I'm not sure that the additional power of the ESC would even be needed. Actually, the only part that I think would be concerning, would be the huge difference in torque between less than 100% throttle and full 100% throttle... primarily during corner exit. I'm guessing that this would be a non-issue with a little bit of experience on the track... but it could be dangerous during the learning process if someone is not careful.

Other than that little bit above (which I believe can easily be a non-issue with a driver mod), I actually prefer the idea of the ESC only spooling up at full throttle. That means 0 spool when you don't want the extra power, i.e better mpg while cruising. I'd likely keep the switch turned to "On" at all times, which actually seems like an unnecessary component for this system if you ask me, considering that it only engages at full throttle anyway.

Hey beta testers,

I got an interesting thing for you. For the last 24 hrs I haven't gotten a single engine code, and I can tell you sometimes I haven't followed the 3500 rpm recommended activation. I'm wondering if the reason this is occurring is because of the snorkel. (I removed mine) Am I just getting lucky here, or is it helping?


By the way I'm still not running the tune.

You need the system to be on for the drag reduction. This helps supply power when not on full throttle.

It was just an example but yeah I agree. I also see where full throttle clearly must be used to make a serious pass or merge. However, my foot is planted on the floor maybe just a few times a month. If I was going to throw down $1600, ide really like to experience it before purchase somehow, or hopefully have some other form of use other than just WOT.
Just my #1 concern atm and lookin for some knowledge
