Hey Fast Freddy, It can maintain boost at WOT for about a minute constant.

During my testing i was able to do 0-240km whilst still developing boost. As a matter of fact i did 2 back to back only slowing down to 0 in between.

1/4mile, half mile will not be a problem AT ALL.

On the street it is 100% impossible to get the system to a point where it will not put you back in the seat.

Was the drop in HP gains at high rpm a result of voltage drop and therefore less compressor flow?

Thanks,

Power drop is due to the compressor running at a static RPM. This RPM equals 4.5psi boost down low where the engine is inefficient and about 2psi up top where the engine is very efficient.

My God, they come out of the woodwork like roaches. Just when you think you've killed the last one, another crawls out.

Its alright, hes asked a couple questions in the other Phantom thread too.

Im glad to set the record straight for anyone that has questions.

Fenton... you and the others testing this product have had the patience of Saints answering the questions and complaints. Thanks for your time and ability to keep things civil.

Bob,

I have a header, overpipe, front pipe, Cat-back, intake , pulley, FA20Club Ecutek tune and I still need a bit more power.

By assuming an N/A car with all those bolts on is developping lets say about 185-190 WHP already.

If I add this electric supercharger mod on top of that setup do you think I could be looking forward another 20-30 extra WHP like it did to a stock car ?

There is no reason it shouldn't. However anything would just be speculating.

Well if that is the case, that means we should be looking forward 215-225 WHP.

We are talking about an FR-S that would make a solid 250-260 crank hp.

With such extra power I'm confident my FR-S could make the 1/4 mile in 13.8 - 14 seconds instead of 15 seconds.

This is what I need for next summer.

With a little more technology there's some pretty solid potential. If you could fit a motor with more RPM or more voltage, add a speed controller, and tie that to engine rpm you could hopefully keep 4.5 psi to redline.

That would keep you from having to resort to 7 psi at peak torque, where it could detonate without an IC, to get 4.5 at redline. You could also run a wastegate on the charge side

Trust me Rob is the man when it comes to this. The sad fact is the energy to create 5 psi at redline is 15 to 20 kW if I remember correctly.

Most people think well just turn that motor a couple 10,000 rpm more and your there. Unfortunately all that increases the motor required, controller required, batteries required and so on. Once you get into those wattages you are talking about cooling every component and the list goes on and on.

Can you imagine the batteries required for even a 30 second shot, times what we have now by 5 and your trunk is half full.

Short answer is yes absolutely its possible but you are talking about more money than most of the turbo kits and at that point the costs outweigh the benefits of non parasitic boost.

As tech evolves the price to performance will continue to improve.

I see you said IF you had better technology, which is good, whereas a lot if people just say crank it up. Lol

This would also add a ton of money but the motor could power a supercharger with a gearbox. That would require more torque but less rpm. But yes as you stated the price of the batteries would sky rocket since I would imagine lipo would be needed and when not controlled correctly burst into fire. Eek!

Anyways cool idea and solid low-midrange gain.

The real problem is that you can't tune around incorrectly matched headers. They will be fighting your efforts the whole time.
For mild boost (electrocharger anyone?) I would expect that the stock system with its narrow tubing would work quite well, keeping the exhaust velocity up and enhancing scavenging. You might see an improvement with high flow cats but the rest of the exhaust should be fine.

"Here comes the big one. The system usage is designed around a single pull and upon throttle switch activation, not in a volley of consecutive back to back ones. Anyone catch my WOT mentions? There's nothing sinister about any of the previous references, only that it's just that – Wide Open Throttle. Notice that I didn't say it would be great for DRAG and or DRIFT applications? That's because this system will not activate in partial throttle, at all. This is where the Phantom ESC differs, and slight adjustment in driving styles are needed.

Think about this real quick – you're in the burnout box ready to rumble. You launch, floor it, hit rev limit and grab second. At which point in time, the recharge isn't going to be full when you go wide open in that gear. Additionally, with each successive gear change, the rate of 'recharge' that the batteries provide will be diminished and your IATs build up, producing less than optimal results. It's still better than stock, all things said. Same issues apply with drifting."

Bob had the prelim kit with only 1 recharger

All the testers have the double recharge now and it makes a dramatic difference on how quickly the system comes back to full.

Either way I appreciate Bob's opinions on the kit and your interest as well.

Time will tell how this kits evolves but there has already been a lot of advancements even in the last 3 months.

I believe ThaTruth is planning some drag time in the future at which point we will see more proven results over the dynos.

Thanks Fenton. I do follow the Phantom threads but missed the fact that Drift-Office had tested an older version. I know that this is far from a drag car but look forward to 1/4 miles results to more accurately quantify the actual performance enhancement provided by this ESC.

Still interested and watching...
