Re: Demo: 2.slow electric supercharger

Hey there, thanks for getting back to me. I actually was looking at some Electric Superchargers on ebay. I have a 2k VW JETTA 2.0L (MK4)
Had spoken to some one @ Tunedub who mentioned your (products). So, when will you have these available as I was about to buy one off ebay? And I take it you are in cowtown as well? Cheers

Blast from the past, I have more of a current posting elsewhere, but yes, we are going to be releasing our product very soon. What are you driving etc.

Re: Demo: 2.slow electric supercharger

Can you tell me if you are still selling the Electric Super chargers and it seems your website aint working? Thanks

Hey guys/gals,

we have or are about to launch our product. How many of you think you would need to see the website, etc, before you would buy, vs coming and taking it for a drive, etc?

Anyway, we think we will have some ready for sale if any of you are interested.

We haven't finalized pricing, but are working on the website.

I was going to put things on facebook, what are your opinions on that? Anyway, if you could you go to the site and give us a like? I need 20 before we become a real entity on facebook.

Re: Demo: 2.slow electric supercharger

Some more tech to add.

The FTSS functionality is similar to NOS, additional power at WOT. The #6445 pack conservative life cycle is 90% capacity after 5000 uses of 15 sec (1/4 mile runs). This is roughly equal to 417 bottles of nitrous at 3 minutes/ bottle. The lithium pack is constantly topped up by the on board charger so no 'refills' are required. After five thousand 1/4 mile runs the pack will still hold it's voltage and capacity to 90%. The #6830 pack doubles the above.

Financial tech:
The NOS'S cheaper initial system would cost $41,700 during that time in refills. It's $10/lb at the two places I found in Calgary. A bit over the top, but $100 /bottle refills add up quickly!

Re: Demo: 2.slow electric supercharger

Well yes silly but that would raise the price considerably for them. But primarily I don't know if it would work still. The motor could be 1000 watts or something. If it's draining a 24v 6amp (guessing) lion in seconds, it is def a hungry biznatch.

Couldn't be any worse then a battery and related charging system. Plus then it would make it more useful to use.

Re: Demo: 2.slow electric supercharger

Thanks for the input guys. We will be updating the website this week and spell check :-).

We will also be reviewing the technical information and everything to make sure it's clear and accurate. Please bear with us it's under development.

Re: Demo: 2.slow electric supercharger

You of all people should know that it is pretty easy to make a 18 or 24 volt motor work off of a 12 volt car battery.

Re: Demo: 2.slow electric supercharger

a) it's spelt "continuous" not "continuas" might help to run a spell checker to look more professional

b) are you draining the battery to zero volts, or close to? The graph kind of reflects that on charging. You're probably aware that lion doesn't like to be drained, and with a "cycle life" of 5,000 that only allows for 13 uses a day in a year. One night of cruising with a group and you'll use at least 50-100 uses.

c) The size of the outlet/inlet and the turbine may create a performance issue when the motor is not powered under normal driving? The engine will have to suck a great deal harder to obtain an effecient amount of air. You'd need the motor to be powered constantly with a custom pwm/rpm table for each vehicle to makeup for the loss of regular drivability power. pic

d) Using a brushless motor was a very smart idea and it probably can spin at an insane speed. It is a great technology. The motor is most likely 18 or 24 volts, that's why it can't run off the car battery/alternator

e) Venting the valve cover to atmosphere won't make it DOT street legal. It will only work in a province like Alberta which does not have a smog test.

f) I'd be curious to see a MAF voltage log (not cfm) of the same car with and without the unit installed/engaged.

It would be neat if your system works. A little on the expensive side. It will be more cost effective and faster to install nitrous with a dry 15 shot. Or a wet 35+ shot. And those are very very very safe nozzles with greater gains for a better price. Work on your pricing .. I know that is tough as a startup.

If you'd like, we can put you on a dyno one evening as a third party to validate your claims. i had mentioned it before and the offer still stands. If your system does indeed work, having a bunch of us and a reputable company backup your claims will help sales. Let me know and we'll work something out when i'm back in town next week

Re: Demo: 2.slow electric supercharger

Sabby see scenario 2, AKA a bypass to get around this as a flow restriction

Re: Demo: 2.slow electric supercharger

On a 1.8t you could use a hobs switch to shut the unit off once you build boost. I don't see much need for a device like this personally, but if someone wants to try it the results could be interesting. My gut feeling is that it will limit flow as a restriction in the intake path once the turbo starts spooling.

Re: Demo: 2.slow electric supercharger

Guys: some more details on using this as an anti-lag device.


FTSS-4 is capable of flowing up to 325-350 cfm with positive pressure (0-0.5 psi). The 1.8t @ 10psi & 6000 rpm moves approx 300 cfm.*
Version 1: *Install the supercharger between the MAF and the turbo. *Micro *switch to activate @ WOT. *At partial throttle air will easily flow through the supercharger without restriction, at full throttle the supercharger will instantly raise pressure to the turbo inlet. *The turbo essential gets a higher atmosphere, say 3 psi + atmos (13 psi in Calgary) = 16 psi. *
Version 2: Same install location, but with a bypass flap, tee'd in and located from the inlet of the supercharger to the outlet of the supercharger, it needs to be at least 2 1/2" diameter tubing. *Same WOT micro switch on the throttle and an addition switch/ lever that is tripped by the wastegate. *Scenario: full throttle applied, supercharger activates and positive pressure closes flapper valve, wastegate opens (when full turbo boost is reached) and disables supercharger, flapper valve will open because of vacuum. All this would happen in less than 2 seconds and remove lag.

A similar setup was done on a 250 HP legacy turbo. *Launch from a standstill was dramatically improved. *The car had an automatic transmission and during driving at speed the downshifts insured quick boosting of the turbo at WOT. *A manual car would greatly gain from this set up.

Re: Demo: 2.slow electric supercharger

Holy. You guys are on a way nother playing field than me. This is why we have made the DIY kit. We never thought that this would have been the first out of the gate.

To answer most of above (going off memory). Yes, motor is super efficient, but it still needs a battery. 4psi is a lot to ask of those little motors. Battery and charger is like a re-fillable nitrous system. The tank is about 3-5 minutes. Depends on temps, etc. It recharges at a 10:1 ratio. 1 second off run time needs 10 seconds to recharge.

No intercooler required as it hardly heats air. 4psi is not that much(again see chart). We have to stay within stock fuel system for the intro system.

We agree that if you could make that engine less laggy, this ccould help. However, we are busy trying to fit it onto stock vehicles, going from n/a to our s/c. I have to check to see what has changed. I don't think its much on the mechanical side, so those numbers should be close. Check that one sheet we have on the tech section with the charts. It is accurate, unlike most else on that site (still under development).

Thanks guys.

Re: Demo: 2.slow electric supercharger

Nvm got what you are saying. I still think it will be a restriction and you will lose at least a few psi because of it however. I am talking to a custom tuning guy from the US to see if he thinks that this is even possible.

Re: Demo: 2.slow electric supercharger

If the supercharger is supplying its maximum flow to the inlet of the turbocharger before it has spooled and the supercharger is capable of 4 psi then there will be 4 psi between the two and probably a little less between the turbo and the intake. But once there is enough exhaust flow to begin to spool the turbocharger and the turbocharger starts flowing more than the supercharger can deliver the 4 psi of boost on the inlet side of the turbocharger will dissipate and vacuum will be created between the supercharger and turbocharger. Once the manifold pressure exceeds the maximum pressure of the supercharge a waste gate set at this pressure would relive the vacuum being generated by the restricting supercharger. The pressure switch would disable the supercharger because at that point it would just be a waste. It is no different than the pressure dropping as the engine speed increases on the 2.0L.
