Default speed gap between gas and electric touring cars

I was thinking about what it would take for nitro and touring cars to compete head to head.

What are some of the(not ROAR legal) things a person could do to speed up a 1/10 scale electric touring car on asphalt road courses, without doing major modifications to the drive train? (not something like having 2 motors)

1. Add another cell to Battery Pack, (7 cell 8.4 volt)
2. 6 or 7 turn motor
3. foam tires on asphalt
4. low profile aerodynamic body
5. major weight reduction

What else can you think of ?


Would a 2 speed transmission of some sort help?
Would there be an economical way of adding traction control?
Maybe using the third channel for braking or gear shifting?
What about g-force sensors connected to a servo that could alter suspension or connected to ESC.

At our local track (140x80) the Electric Mod sedans make the high end Nitro sedans (MTX-3's with Modified 3 port .12's) look dumb. A good driver with 19T is faster than the nitro sedans.

It takes a bigger track for a nitro sedan to wind out and get faster than an electric sedan.

At our local track....we EPs on super stock 23T motor are running neck to neck with the GP...track size is 'bout 100'x50'....we're 'bout the same on the straight but EPs tend to shine in the infield....and Adrian....you're right, the GP boys need a bigger track for their engine to achieve more top end at the 2nd gear.

electric cars are quicker than gas cars. because a electic motor makes a gob of torque at 0 rpm where as a gas gas needs higher revs to really get it going. also, a stock gas car will have a higher top end than a stock electric car.

At my track the electric touring mods do about 1 lap more in a 5 minute race compared to the gas touring cars. The lap times are around 20-21 secs and we do 15 laps in the race. Large outdoor ashfelt track with all cars running foams.

Unless you start talking about !/8 nothing is faster than those babys, even on the infeild, providing the car is dialed of coarse.

Which GP car are you refering that to ? The entry level RTR ones ?
I had a 9t powered by GP3300 matched and went head to head with a 5 port stock 705. Mine could keep up till just before the 705 kicked into 2nd gear then after that it was a long bubbye in a smoke.

Brushless, 8 cells, 30mm foams, GTP style body or brushless, 6 cells, and a pan car.

at a track in sydney that is frequented my the best electric drivers and a nitro feild that would be considered to be ranging from beginners to medium experienced racers the electric drivers are doing 22 laps and nitro guys 21.

considering that nitro cars have a higher cg, and more weight i would say this is pritty good for the nitros. a top nitro driver can do 22 laps and maybe only 5 racers in the state of NSW can do 23 in mod (surikarn, the world champ raced at this track and did 23 in nitro and electric......i think )

When it comes to corner speed, electrics are way faster than GP, even with rubber. Down the straight, it really depends on the length of the straight, but usually a car with a good brushless (ie : not the novak) beats the sh... out of the nitros. Only advantage of the nitros, they can refuel and carry on, while we have to change battery and often cool down the electronics after a run.

lol looks like u dont need anyting out of the ordinary to get a electric tc to beat a nitro tc.

Its the same at our track over the course of a 5 minute heat the same driver running electric will normally out do his run in nitro..

Its a bit closer at our track since our straight is about 180ft plus. But on most parking lot tracks electrics are dominate. ITs not till you go to permanet nitro based tracks that the nitros will run faster then the electrics.

Its not fair to compare electric sedans to the 235 or 1/8th cars although i have scene the 235s get smoked by electric and nitro sedans.. Again on parking lot tracks.

On smaller tracks electric cars will dominate, however there might be some options nitro cars could do, such as lowering the internal drive ratio by changing pulleys (such as the Yokomo GT4 optional pulley set) , and switching to a motor and pipe with better bottom end power. Most motor and pipe combinations are made for top end power. If there was a way to reduce the weight of a nitro sedan then that would help, maybe even nitro pan car. An 8th scale would probably have the most difficult time on these smaller more technical tracks, which are meant for tracks that have wider lanes and longer track lenghts.

On larger tracks electrics will not be able to compete with nitros, and I really think defeats the purpose of performing all those mods dollar for dollar.

Mabuchi 540's, 1200 stick packs, and add 3 pounds ofweight and the electrics will be close in speed to nitros......LOL
