Looking for: Renesis HP/Torque Curve
Hi, my name is Cody Rients and I am currently a student enrolled at Arizona State University and as part of a class project I am involved in, we are designing a performance hybrid car. Since I am a huge rotorhead and own a RX-7 I choose to use a Renesis Rotary engine as part of my car. To perform analysis of my vehicle it would be extremely helpful if I could obtain a horsepower/torque curve for a stock Renesis engine (even an RX-8 dyno chart would be helpful). If anyone could just e-mail me an excel file or something with the data points for even just the torque curve I would be grateful.
Thanks in advance, Cody Rients e-mail: Cody.Rients@asu.edu |
Cody-
Check out the section "RX-8 Faq" on this forum. There you can find the original RX-8 HP/Torque curve on a graph. |
Two 100% RX8s...same dyno, same day...minutes apart.

what's torque ? :p
|
It would be nice if I could find a graph like what is in the FAQ section, except one that has the U.S. models horsepower and not the 250-hp japan engine.
|
Hope this helps
....data table is based from on dyno. For more info, follow the link to my site.

Thanks for the help finding a dyno chart!
Another thing I have been searching for with little luck is envelope dimensions of a Renesis engine (Length x Width X Height)? |
Since you are sapping us for info, I would like to know what exactly you are doing. I'm really interested in hybrid gas / electric (and pure electric). Are you designing from the ground up or trying to convert an existing vehicle? Are you going to "put" an electric assist on the drive shaft or "put" some in-wheel electric motors on it? GM apparently has some in-wheel motors that are good for ~35 hp each. They had some truck making 70 more HP from putting the motors on the rear wheels. With some regenerative breaking, this would be a great way to add some extra permanent oomph to the RX-8 (esp. since the power is available 100% of the time). The only downside is the extra unsprung weight would really mess with the handling. Sounds like a fun project. You might want to check out the Toyota Volta for inspiration...

Have a look here :
https://www.rx8club.com/showthread.p...g+power+torque It comes from a SAE tech paper. |
If some people are interested here some of my teams overall specs outlined in our proposal. My team has 20 people and then we are subdivided intoe body, chassis, electric motor and intenal combustion engine. My focus is on the ICE.
Overall Vehicle Specifications: Pricing: MSRP: $15,000 - $20,000 General Info: Body: Two-seater Hatchback Doors: 3 Seating Capacity: 2 Power Train: Drive Train/Layout: Front-mid engine/Rear wheel drive Power Train: Parallel hybrid Electric Motor: Electric Motor (hp): 19 Electric Motor (lb.-ft.): 100 Engine Type: RENESIS 2-rotor rotary Displacement: 1.3 Liter Compression Ratio: 10.0:1 Horsepower: 238 Hp @ 8500 RPM Torque: 159 lb.-ft. @ 5500 RPM Max. Engine Speed: 9000 RPM 0-60: 4.3 sec. ¼ mile: 12.6 sec. Transmission: 5-speed manual Top Speed: 160 mph Final Gear Ratio: 4.100 Differential: Limited-Slip EPA City: 26 MPG EPA Hwy: 32 MPG Safety: Airbag: Brakes: Front: Disk Rear: Disk Dimensions: Head Room: 940 mm Leg Room: 919 mm Hip Room: 1,306 mm Shoulder Room: 1,407 mm Cargo Space: 1,862 Liters Specifications: Wheelbase: 2,413-2,667mm or 95”-105” Overall Length: Width: 1,524-1,770mm or 60”-70” Height: TBD Curb Weight: 2000lbs. Weight Distribution Front/Rear: 50/50 Tires/Wheel Size: TBD Steering Type: Rack and Pinion Turning Radius: TBD Steering Ratio: 3.5 turns; lock to lock Suspension: Front: SLA Rear: SLA Fuel Capacity: 12 gallons |
Electric Motor (hp): 19
Electric Motor (lb.-ft.): 100 I'd take a look at the GM product. Apparently Bridgestone has one as well (PDF attached). GMs are putting out 35 hp each (don't remember the torque rating, and google didn't help me this morning... looks like a reindex). That would bump your mileage up alot. The electric side just look really anemic compared to existing offerings from Honda (73 HP / 79 ft lbs...okay, not really that bad compared to Honda) and Toyota (67 HP / 295 ft lbs). |
hehe why not put 4 of those motors on teh 8 one fo reach wheel:D wonder how much they weigh...hmmm but 35 hp a pop would be nice. wonder how plausible it would be to do. maybe tonight when i got nothign to do i'll check into it:D
