Full throttle Electric Supercharger Build Thread

[shif7i7down]

Took the frs for a log run right after the 4.67 fd install, feels pretty damn good... the whp and trq curve are identical to the stock 4.1 fd when it's corrected for final gear ratio change.
But i also did a comparison of "what is the equivalent whp and trq" If the 4.67 was still a 4.1 and the curve is at a equivalent of 268whp and 245trq if it was a 4.1

Note: I'm not saying that the new fd added whp and trq. I'm only saying that it's 268/245 equivalent,,,,if that makes any sense.

Video or it didn't happen

I will be going the traditional supercharger route. This seems too much like a turbo setup.

Video of gtec run will come soon. As for the hp comparison it's just from the openflash tablet log using virtual dyno. Vd may not be super accurate but it's a good tool to used for before and after mod comparison.
For example. Pre fd install the logs showed 220whp 196trq
After fd install the logs showed 268whp 245trq.

Chad where are you at. It's hard to describe the linear feel of the system. Maybe someone can give you a ride.

You do realize that WOT can happen at 2k RPM, giving you full boost at the very bottom of the power band, right?

The big difference between this kit and either a turbo or a supercharger traditionally is zero boost lag. It's power on demand, wherever you want it and whenever you want it. Both turbos and superchargers build power non-linearly (more or less) and hit max power at the top of the power band.

I'm not sure how that is "too much like a turbo setup."

I was in the same boat as you -- was interested in the Vortech kit originally. Bought this kit for funsies to try out for a month or two, never looked back at the Vortech kit since.

Either way, let us know if we can answer any further questions to help with your decision. You can't offend us at least not very easily -- I would just feel bad for you if you choose against this kit without quite knowing what this option is. But I also won't ever blame anyone for going traditional FI. Different strokes.

100 percent agree. This system is not for everyone and I have no problems with people choosing full time FI if it meets their goals.

You will never be able to make everyone happy that's why it is great that we have so many options.

To each, their own choices.

Speaking of rides. @shif7i7down, don't suppose that you'd be close enough for a meet and ride sometime down the road. I do make an annual journey to visit relatives in Janesville and wouldn't mind a detour.

This kit fits my needs perfectly and I'm thrilled it was available. What great timing. Bought my BRZ after driving a piece of crap for 14 years and, just a few months later, "Oh, look, I can get more power with this new-fangled thing". Just what I need without what I've now come to learn can sometimes be an unending hassle of full time FI.

I do a ton of city driving. That's where I live, work and play. Once, maybe twice a day, I need the extra zip to negotiate traffic. This kit has been a Godsend. I remember reading a thread about the twin's stock power (one thread of maybe 1,000), and somebody wrote that stock is just fine for passing on the highway. I disagree. To me it felt like it was taking forever to pass going uphill. Haha, not anymore!

So do you have to click a switch to turn on the extra power? How does this system work?

It is connected to the throttle and engages at 80 percent physical throttle.

This is very similar to how a turbo would work....you can never get a turbo to go full boost with half throttle...hell even getting a turbo to do half boost at half throttle is challenging... Most often a turbo likes to spool to 0 and then to its max psi. It is very hard to get a turbo car to stat at 7 psi if 10 is the max. This is of course dependent on the car and turbo.

I had a 2011sti stage 1 for two years and it was like switch. You would either have no boost or full boost....and it was a blast

Right now my FRS is as fast as my sti was but it has much more linear torque.... Go WOT and within half a second you have all your torques and it tappers to redline just like a standard NA or positive displacement engine would be.

My sti was go WOT, nothing, nothing, nothing....bam 320tq.

I'm certainly not the most qualified here to answer, but

1) Switch under the accelerator is thrown at approximately 80% WOT.
2) Signal is sent to controller.
3) Controller sends signal to compressor, telling it to spin.
4) Compressor spins at approximately 30,000 rpm (or is it 50k?), creating up to 5 psi of air flow blowing into the engine.
5) Car rockets off.
6) Ease off on accelerator and batteries quickly recharge. almost always quicker than you deplete them, unless you're tracking the car heavily.

The best description is at the Phantom website:

The 250 is about 43k rpm

I don't even know what I'm running anymore...
