Full throttle Electric Supercharger Build Thread

[Mars2]

SO you think that at 5000 rpm on light throttle the esc doesn't create any restriction and their for the electric Sc will never kick in. Even if i stay their for very long period ( over 1 hour)

[Mars2]

I like that ESC just trying to find out if it fit well to my country where we can drive at high speed for quite a long time. I mean not red light racing

I drove from San Francisco to San Diego with the system( 500 miles) The only time the system engaged for me was when I was passing traffic or the drag reduction kicked in a for a wee bit with moderate acceleration. Anytime I was cruising or under cruise control the system was never running. I never felt at anytime I was running out of charge.

what speed where you cruizing? 180 km/h is 110 Mph or around 5000 rpm in six gear
at that speed on light throttle engine is on vaccum

Hah not that fast. But based on the fact that at 5000 rpm in 4th gear the system does not engage... I think you are good. I'll do a couple tests in 4th or 3rd gear for you.

Hi Mars,

I have drove for long periods of time at 150km/hr and once a steady state has been reached DR does not activate. If you push the throttle down to go up a hill or pass someone it will engage but DR uses very little power in comparison to full boost.

The difference between Europe (wish we were all as responsible) and the US, is that we have speed limits on major roadways. A true autobahn here in the states would be a nightmare for the politicians.

But here in europe when I drive for 2 or 3 hour's at 160-180km/h what will happen .
It happen to me often to drive at least 1 hour at steady 160-180 km/h not moving my right feet by more than 2mm and never touching the brake.
So will I then run out of boost (battery)

I think that maybe you are under the misunderstanding that this works like a KERS system or like a Prius. The brake doesn't have anything to do with the recharging. The batteries are constantly being recharged by the alternator and the charge controller. So unless you are on constant full throttle you really will never run out of boost. At least on the street as a DD.

I think he was worried about the battery possibly draining since the ESC is partially running for a long time at a very high speed. Only mentioning the brake to say it's a solid block of time driving.

Ya this isn't something that is really easy to test here in Canada. Longest i would ever go that speed would be 30 seconds or so and even then our roads aren't built for speeds like that.

Anything over 150km/hr on a major highway and the cops can impound your car and suspend your license. If im not mistaken its actually a criminal offense.

I don't see how speed has anything to do with it.
The ESC is only engaged at full throttle.
The speed limit here on I-95 is 70 MPH [75].
I can only maintain full throttle for seconds at a time without really standing out.
I live in flatland here so I can't comment on great canyon roads where full throttle would be used more often but here in flatland the system is ideal.
As far as the drag reduction goes, it is absolutely a minimum load on the system. The most I've seen it drop was from 28.5 to 28.3 for maybe a second then it totally recovers.

The simplest way to answer this question would be for someone, anyone that could cruise even for a few seconds (10-20 maybe) at 160-180kph, and see if it requires the DR system to activate on a nice big level piece of road. I'd bet that that at speed, the DR system would not run constantly. It really would depend, on how much of the engines total output, at that specific rpm and speed, was required to sustain the speed. So can the FRS's engine make enough power at about 5000rpm, to sustain 160-180Kph (or 100-110mph), with the Phantom system installed, not relying on DR? I'd bet it can easily, as this is no-where near the cars top speed.

Unfortunately I have cops all over around me.

Guys, don't be dense... Use a lower gear to prove your point... Physical speed is irrelevant to his question, engine rpm is what matters..

The answer he is looking for is simple.

No, you need not concern yourself with this issue. Battery charge speed is >= rate of use for cruising throttles.
