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:
Â;-) HERE ARE SOME PICS AND INFO ON THE NEWEST DESIGN
ESC-250C, ESC-350CÂ;-)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 FORÂ;-)PERFORMANCE ENTHUSIASTSÂ;-)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.
Â;-) THE ESC-350CL AND ESC-650CL LOW BOOST MODELS ARE 2-3 PSI CENTRIFUGAL SUPERCHARGERS. THE 350 IS FOR SMALLER 4-CYL UP TOÂ;-)2.5 AND THE 650 IS FOR ENGINES UP TO 5.0. THESE AREÂ;-)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.Â;-)AÂ;-)GOOD BATTERY, BATTERYÂ;-)CABLES, ETC ARE A MUST.Â;-)SIMPLE FMU, BOOST GAUGE, ETC IS NEEDED.
Â;-) THE ESC-250CM, 350CM AND 650CM (MEDIUM BOOST) ARE 5-6 PSI ELECTRIC SUPERCHARGERS DESIGNEDÂ;-)TO BE RUN SAFELY ONÂ;-)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 TOÂ;-)5.0. A PAIR OFÂ;-)EXTRA BATTERIES, A MULTI-FARAD CAPACITOR,Â;-)AND 12/24 SWITCH ISÂ;-)WHAT IS RECOMMENDED FOR THE ELECTRICAL SYSTEM.Â;-) GOOD BATTERY CABLES, ETC ARE A MUST. THEÂ;-)FUEL SYSTEM CAN CONSIST OF AN FMU, OR AN ADDITIONAL INJECTOR.
Â;-) 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.Â;-)THE HIGH BOOST UNITSÂ;-)ARE $1495 FOR THE BLOWER BY ITSELF. THESE MORE POWERFUL UNITS DRAW MORE THAN DOUBLE THE CURRENTÂ;-)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.Â;-)THE HIGH BOOST VERSIONS ARE SUGGESTED FOR DRAG RACING APPLICATIONS ONLY.
Â;-)Â;-)
Â;-)Â;-)LIST OF REQUIRED ACCESSORIES:
Â;-) 1--BATTERIES (BIGGER BATTERIESÂ;-)WILL GIVE ADDITIONAL RUNNING TIME)
Â;-) 2--BATTERY CABLES & TERMINALS ($40)
Â;-) 3--FUEL CONTROL--FMU ($100)Â;-)OR ADDITIONAL INJECTOR SETUP ($250)
Â;-) 4--BOOST & AIR-FUEL GAUGES ($100)
Â;-) 5--COLD AIR INTAKE & PIPES ($50-$70)
Â;-) 6--SOLENOIDS--12/24 SERIES/PARALLEL SWITCH ($100)
Â;-) 7--ACTIVATION SWITCH--PUSH-BUTTON, TOGGLE, OR MICROSWITCH ($20)
Â;-)Â;-)8--MISC WIRING AND CRIMP TERMINALS ($25)
WE RECOMMEND WATER/ALCOHOL INJECTION WITH ANY SUPERCHARGER APPLICATION:

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 @Â;-)5-6 PSI, THREE 6.5HP MOTORS @ 24V)
PIC 3--ESC-350CH (350CFM @Â;-)5-6 PSI, THREE 4HP MOTORS @ 24V)
PIC 4--ESC-250CM (250CFM @Â;-)5-6 PSI,Â;-)ONE 6.5HP MOTOR @ 24V)
Â;-)
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
Â;-)
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. 14.3Â;-)X 746 = 10,667WATTS /24 VOLTS = 445 AMPS
Â;-)
FORMULAS ARE SIMPLE:
Â;-)
PSI X CFM /229 /BLOWER EFFICIENCY =POWER REQUIREMENT
ELECTRIC MOTOR EFFICIENCY--6.5 @24V AND 8.2HP @ 36VÂ;-)=50% EFF
Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-) Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-)Â;-) 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
Â;-)
305 X 6 /229 /.70= 9.5HPÂ;-) 9.5 X 746 /.6 = 12,000 WATTS /24V = 500 AMPS
Â;-)
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.
Â;-)
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)Â;-)OR UNDER 10 MINUTES TO FULLY RECHARGE.
