Esc Turbo/supercharger Electronic. 20 Psi?

[AlarmedBread]

Wait, what? More power for longer, quicker and cheaper? Whaaaaaaaaa?

Alternaters are at best about 60% efficient, as are electric motors. Shoving large quantities of air using electricity is just not efficient in a car.

Well, I said motor, meaning electric. They should spray it into the electric super charger's motor and blow them selves up. ;)

Nitrous Oxide isn't flammable. It's an oxidizer, meaning it creates (adds) oxygen. This is why with a bad setup, you will blow your engine due to a extremely lean mixture.

if batteries didn't weight around 40-50 lbs i would do it with around 10 batteries hooked together, and steal teh alternator out of a lifted diesel truck. I mean i might even go get a turbo out of it because all you have to do is duck down and stand up straight they would never see you LMAO

the kit comes with a 3 bateries that are what recharges for the boost. and with a new stronger alternator, it takes about 5 min to recharge for another boost. i mean i would go turbo, but i have a tendancy to just love the boost and gas it 10 miles over the speed limit. thats y i got 2 point left on my lisence. and its not like i need the boost constantly. the average time im at a stoplight with a tuner car is like once every 2 weeks.

"A SPDT switch bypasses your alternator while the ESC 400 is running, eliminating all parasitic loss." The driver would have to flick a switch before hitting the accelerator and flick the switch again to start recharging the batteries".

was researching and found thomas knight posted in 2005 about his product. now theres a newer ones

GEOFF KNIGHT HERE--FINALLY GOT THE ACCOUNT TO WORK. THERE ARE MANY QUESTIONS AND I HAVE THE ANSWERS, BUT I WILL SKIP MOST QUESTIONS BECAUSE THEY PERTAIN TO OUR ORIGINAL UNIT WITH THE EATON SUPERCHARGER. WHILE THAT MODEL 400 & 550 ARE STILL AVAILABLE, OUR LATEST VERSION IS BETTER SUITED FOR STOCK ENGINES AND MAKES 5-6 PSI BOOST. HERE IS THAT INFO:
HERE ARE SOME PICS AND INFO ON THE NEWEST DESIGN
ESC-250C, ESC-350C AND ESC-650C, OFFERED IN THREE BOOST LEVELS:
HERE ARE THE MODELS AND THE DISCOUNTED INTRODUCTORY PRICING. RETAIL IS 25% HIGHER.
CL--LOW BOOST (2-3 PSI--$595) AVAILABLE NOW
CM--MEDIUM BOOST (5-6 PSI--$995) AVAILABLE NOW
CH--HIGH BOOST (6-12 PSI--$1495) AVAILABLE JAN, 05

THOMAS KNIGHT ELECTRIC SUPERCHARGERS HAS RELEASED OUR NEWEST DESIGN OF LOW AND MEDIUM BOOST ELECTRIC SUPERCHARGERS. THESE SUPERCHARGERS ARE CUSTOM-BUILT TO ORDER BASED ON ENGINE SIZE. USING A COMBINATION OF HYBRID CENTRIFUGAL SUPERCHARGER COMPONENTS COMBINED WITH OUR HIGH OUTPUT MOTORS WE HAVE DESIGNED THESE FOR PERFORMANCE ENTHUSIASTS ON A BUDGET AS WELL AS THOSE WANTING INCREDIBLE AND RELIABLE PERFORMANCE FROM STOCK ENGINES. HP IS INCREASED AT A RATE OF 8-15 HP FOR EACH PSI BOOST YOU RUN.
EXAMPLE: A 140HP 2000CC 4-CYL RUNNING 2-3 PSI WILL MAKE AN EXTRA
20-40HP, AND AT 5-6 PSI MAKE AN EXTRA 50-90HP.
THE ESC-350CL AND ESC-650CL LOW BOOST MODELS ARE 2-3 PSI CENTRIFUGAL SUPERCHARGERS. THE 350 IS FOR SMALLER 4-CYL UP TO 2.5 AND THE 650 IS FOR ENGINES UP TO 5.0. THESE ARE DESIGNED FOR SIMPLE INSTALLATION AND WILL NOT REQUIRE UPGRADING THE FUEL SYSTEM OR ALTERNATOR. STARTING AT $495 FOR THE SUPERCHARGER BY ITSELF, A COMPLETE SYSTEM CAN BE BUILT FOR UNDER $1000. A GOOD BATTERY, BATTERY CABLES, ETC ARE A MUST. SIMPLE FMU, BOOST GAUGE, ETC IS NEEDED.
THE ESC-250CM, 350CM AND 650CM (MEDIUM BOOST) ARE 5-6 PSI ELECTRIC SUPERCHARGERS DESIGNED TO BE RUN SAFELY ON STOCK ENGINES. THE 250CM IS FOR 2.0 AND SMALLER ENGINES, THE 350 IS FOR ENGINES FROM 1.8 UP TO 2.8, AND THE 650 IS FOR ENGINES UP TO 5.0. A PAIR OF EXTRA BATTERIES, A MULTI-FARAD CAPACITOR, AND 12/24 SWITCH IS WHAT IS RECOMMENDED FOR THE ELECTRICAL SYSTEM. GOOD BATTERY CABLES, ETC ARE A MUST. THE FUEL SYSTEM CAN CONSIST OF AN FMU, OR AN ADDITIONAL INJECTOR.
THE ESC-350CH AND ESC-650CH HIGH BOOST VERSIONS MAKE UP TO 12 PSI, AND ARE SPECIAL ORDER ONLY. THE ENGINE SHOULD BE PREPARED WITH FORGED INTERNALS, AND AN UPGRADED FUEL SYSTEM. THE HIGH BOOST UNITS ARE $1495 FOR THE BLOWER BY ITSELF. THESE MORE POWERFUL UNITS DRAW MORE THAN DOUBLE THE CURRENT OF THE LOW AND MEDIUM BOOST VERSIONS, SO BUYERS SHOULD HAVE LARGE HIGH-OUTPUT BATTERIES, AND A 200+ AMP ALTERNATOR IN THE VEHICLE TO ALLOW FOR FASTER RECHARGING. THE HIGH BOOST VERSIONS ARE SUGGESTED FOR DRAG RACING APPLICATIONS ONLY.

LIST OF REQUIRED ACCESSORIES:

1--BATTERIES (BIGGER BATTERIES WILL GIVE ADDITIONAL RUNNING TIME)
2--BATTERY CABLES & TERMINALS ($40)
3--FUEL CONTROL--FMU ($100) OR ADDITIONAL INJECTOR SETUP ($250)
4--BOOST & AIR-FUEL GAUGES ($100)
5--COLD AIR INTAKE & PIPES ($50-$70)
6--SOLENOIDS--12/24 SERIES/PARALLEL SWITCH ($100)
7--ACTIVATION SWITCH--PUSH-BUTTON, TOGGLE, OR MICROSWITCH ($20)
8--MISC WIRING AND CRIMP TERMINALS ($25)

WE RECOMMEND WATER/ALCOHOL INJECTION WITH ANY SUPERCHARGER APPLICATION: http://coolingmist.com IS A GOOD PRODUCT

POSSIBLE UPGRADES FOR THE FUTURE:

1- UPGRADED ALTERNATOR (OPTIONAL)
2- BLOW-OFF VALVE (OPTIONAL)

IF YOU ARE NOT SURE WHICH BLOWER TO PURCHASE, CALCULATE WHICH BLOWER YOU NEED USING THE FORMULAS AT THE BOTTOM OF THIS PAGE.

PIC 1--ESC-650CL (650CFM @ 2-3 PSI, ONE 8.2HP MOTOR @ 36V)
PIC 2--ESC-650CM (650CFM @ 5-6 PSI, THREE 6.5HP MOTORS @ 24V)
PIC 3--ESC-350CH (350CFM @ 5-6 PSI, THREE 4HP MOTORS @ 24V)
PIC 4--ESC-250CM (250CFM @ 5-6 PSI, ONE 6.5HP MOTOR @ 24V)

THE FORMULA FOR CFM AT 5 PSI BOOST IS: (CU/IN DISPLACEMENT X RPM)/3456 X 1.1=CFM @ 5 PSI
EXAMPLE: (2.0 IS 122 CU/IN DISP X 6000 RPM) /3456 X 1.1= 230 CFM

THE FORMULA FOR REQUIRED ELECTRIC POWER IS:
(CFM X PSI)/229 X SUPERCHARGER EFFICIENCY X MOTOR EFFICIENCY.
CENTRIFUGAL BLOWERS ARE 70% EFFICIENT
HIGH POWER BRUSHED ELECTRIC MOTORS ARE 50% EFFICIENT
1HP = 746 WATTS
EXAMPLE: 2.0 RUNNING 5 PSI (2.0 = 122 CID, AND THAT USES 250CFM @ 6000RPM)
(230 X 5)/229 /.70 /.5 = 14.3HP. 14.3 X 746 = 10,667WATTS /24 VOLTS = 445 AMPS

FORMULAS ARE SIMPLE:

PSI X CFM /229 /BLOWER EFFICIENCY =POWER REQUIREMENT
ELECTRIC MOTOR EFFICIENCY--6.5 @24V AND 8.2HP @ 36V =50% EFF
4HP @ 24V =60% EFF
CENTRIFUGAL BLOWER EFFICIENCY = 70%
1HP = 746 WATTS
2600/16.6= 157CID X 6000 RPM /3456 X .9= 250 N.A. CFM
DENSITY RATIO FOR 5 PSI = 1.22, SO 250 X 1.22 = CFM @ 5 PSI = 305CFM

305 X 6 /229 /.70= 9.5HP 9.5 X 746 /.6 = 12,000 WATTS /24V = 500 AMPS

THE AVERAGE V8 STARTER MOTOR DRAWS 500 AMPS, SO HOW LONG CAN THE STARTER RUN FROM A BATTERY? SAME LENGTH OF TIME AS THE ESC. HOWEVER, THE ESC IS AT 24V, AND TWO BATTERIES IN SERIES HAVE THE SAME RATING AS ONE BATTERY AT TWICE THE VOLTAGE.

THE AVERAGE BATTERY IS 30 AMP/HRS, WHICH IS 30 X 60 MIN =1800
1800/500AMPS = 3.5 MINUTE RUNNING TIME IF THE BATTERIES KEEP COLD (BUT THEY DONT). SO USE 50% TO DETERMINE PEAK DRAW TOTAL SECONDS.
3.5 X 50% = 1.75 MIN (105 SECONDS, OR TEN RUNS OF 10 SECONDS BETWEEN RECHARGES). AGAIN, USE A 20% RECHARGING RATE TO DETERMINE HOW LONG TO RECHARGE. ALTERNATORS MUST SUBTRACT HOW MUCH CURRENT THE CAR NEEDS TO RUN, AND WHAT IS LEFT OVER IS 'EXTRA'. A 100 'EXTRA' AMP ALTERNATOR WOULD TAKE 20% OF RUN TIME, SO EACH 10 SECOND RUN WOULD TAKE 50 SECONDS TO REPLACE THE DEPLETED CURRENT. AFTER TEN RUNS YOU WOULD NEED 10 X 50 (500 SECONDS) OR UNDER 10 MINUTES TO FULLY RECHARGE.

It was supposed to be a joke. ;-)

I like the switch thing, its like the uber boost buttons on old arcade games!

Now you can have one button on the wheel for nawz, the other for boost!!!!

how many of your turbos push 20 psi?
4 lyfe

uhhh, 20psi is alot for some cars, but others for example my buddys audi s4, is pushing 26psi on a daily driver. another friend of mine is pushing 30psi on his mk4 supra... :wgaf:

[rThor432]

Yeah let me know how that whole electric-turbo-450 hp deal works out. Sounds like BS to me.
