I wanted to share with you all this video of the car my father and EV west built. It will be running in the Baja 1000. Amazing!

Thats mental!!!! Would love one!

What is the motor they used and how many batteries did they use?

What battery type did they use?

Cheers,

Hello Gpilot,

Wow!, very nice, neat and amazing work you guys got going on there!!

I was watching your video here, nice and sweet aluminum bracket for all the Car accessories, like the Power Steering Pump ,AC Compressor and Power Brake Vacuum Pump.

Now, do you have another video where you show the Transmission Bell Housing connection?...meaning "the other side" to the power train drive...

Great to know you are here!!

Hello Soundiceuk,

The Motor(s) are based on the Warp design...Warp 11

EV Source - NetGain WarP 11 Electric Motor...a 2999.99 USD Motor...

It is running twin engines. I will get the specs for you. The batteries are lithium ion. They need to be swapped out every 100 miles, which is about every hour when racing. Search SRI EV1 on you tube. There are some more videos. The engines and electrical was done by EV West.

The SRI EV1 race vehicle is powered by a 400kW, 1000A system. *The drive train is powered by two 69 cell battery packs that each provide power to two 9 inch electric motors that are vertically stacked and connected via a 2 inch carbon fiber belt. *Should one pack or motor fail, the other pack and motor can power the vehicle. *The lower motor power take off (PTO) drives the power steering pump.
The car has a total of 142, 3.35 volt, 180Ah China Aviation Lithium Batteries (CALB) on board. Axillary DC power is created for the GPS, VHF radio, lights, cooling fans, horn and intercom from a small group of 4 CALBs connected in series just forward of the center console / dashboard. *The total energy of the 2 battery packs is 82kWh - enough energy to power the average home for a week. *The combined weight of the dual power packs is 1950lbs. *Total vehicle weight (race ready) is 5250lbs. The vehicle produces 535hp and 750flb of torque.
The 2 battery packs take 5 hours to fully recharge. *The CALB’s are reliable for 3000 full and 5000 partial cycles (recharges). *Each battery pack will be charged by a Manzanita Micro PFC 40 charger capable of operating on 110/120V and 220/240V AC and can charge any battery between 12 and 450V DC. * *At an average cost of $0.11 per kWh, and taking 5 hours to charge each battery pack, the cost of charging / recharging is $18.04. *When circumstances allow for slower charge times, solar energy will power the battery chargers at zero cost.
During races that require mobile recharging, Team SRI uses a Perkins 21kVw Diesel generator. *The generator’s fuel consumption is 1 ½ gallons per hour for a total consumption of 7.5 gallons for a 5 hour charge. With current prices of $4.50 a gallon it will cost $33.75 to charge both packs. *A typical class1 race car burns 45 gallons of race gas (C12) in each 100-120 mile leg of the race. *C12 is currently $13.50 a gallon. *The cost of racing a class 1 car for one leg of the race is $607.50. *Cost comparisons for the full 1,000 mile race are noteworthy; $6,075.00 for 450 gallons of C12 versus $337.50 for 75 gallons of diesel fuel – 1/20 the cost. Over the course of the three races in the annual series SCORE-International series, the cost of C12 is $10, 500.00 versus $600.00 for diesel fuel to power the electric generators.*

Cost comparisons of motor costs are even more noteworthy. *A top performing class 1 car uses an LS 7 motor that has been “blue printed”, balanced and ported at cost of $35,000.00. *At the end of the 1000 race, the entire motor must be disassembled and refreshed at an average cost of $15,000.00. *The combined cost of the two electric motors in the SRI EV1 car is $3,000.00. *At the end of the 1,000 race, they will only require minimal refreshment, $1,000.00 would be generous. *The legacy ICE route totals to $50,000.00 where the electric motor route is only $4,000.00 – less than 1/10 of the cost. *For the three races in the SCORE-International annual series, the cost of operating ICEs is $80,000.00 where-as the cost of the EV equivalent is $6,000.00
4 sets of batteries are required to race the SRI EV1 down the Baja Peninsula. *After a set is used, it is hoisted into the back of a “chase truck” and leap-frogged three pit stops ahead of the race car – giving the needed 5 hours of charge time before being used again. *At current prices, the cost of each battery set is $32,000.00 for a total of $128,000.00 for the four sets. *Unlike race gas (once it’s gone, it’s gone), these batteries can be reused over and over. *Converting from LS 7 motors fueled by C12 to electric motors powered by CALBs, would take 1 & ½ seasons to recoup the conversion expense. *Many race teams use their race vehicles for many more years than that, and those that have a higher turn-over rate sell them to start-up race teams who use them longer.
Energy density comparisons from the Aug/Sep 2012 Charged Magazine and in Seth Fletcher’s 2011 book Bottled Lighting, state that lead acid-batteries can store 40Wh of energy per kilogram. *Lithium-ion batteries can store 200Wh per kilogram. *Lithium-air batteries (next generation) will store 1650Wh per kilogram equaling the energy density of gasoline when used in an ICE. *Lithium-air batteries will allow vehicles to travel 500 miles between charges. *Such capacity would only require the SRI EV1 to stop one time during the Baja 1000 which is necessary any way for driver and tire changes. *ICE cars however, will still be pit stopping the traditional 9-11 times. *With each pit stop taking a minimum of 2-5 minutes, 9 extra stops create a disadvantage between 18 to 45 minutes.
