motor fo Z-Cars
 

which is the fastest Z-Car motor? is the 3.0 Z-Car motor really that fast? should i get a faster microsizers motor?

There is a 3.8 that will fit I believe. Consider that if you want faster speeds..

Using a stopwatch I timed my 0-10' runs with the original 2.2 engine and then with the 3.0 engine. My times went from about 4.5 sec to 3.2 sec. This pretty consistent with Atomic Toys findings of 4.6 sec stock and 3.0 sec. with the 3.0 engine.

ok, should i use a microsizers motor to get even faster? what about a dual battery mod?

I believe the 3.8 is the fastest motor period. Don't know anything about dual battery mods.

3.8 Z-Car motor or 3.8 Microsizer motor?

Either / or. They both spin at 38000 rpm right? I dont think there is a 3.8 z-car motor, so that may not be an option. But you can get 3.8 from other companies.

Z-car makes a 3.0 motor.

Yeah, biggest motor for Z-car is 3.0 in fact I don't think that the 3.8 is even an official Microsizers motor...I think it's like an aftermarket motor. From what I've heard they're interchangeable tho.

Yup, I think your right.

ya the microsizer motors are interchangeable with Z-Cars. ow fast is the 3.0 Z-Car motor?

The 3.0 does 0-10' in 3.2 sec. when I tested it. On their website it says it'll do 3.0. With the gearing ratio they provide it is slow off the line but top speed is good. I have a friend with a clone that is really quick. Using the same gearing ratio his is faster than mine so I figure his car must've come with a 3.2 or 3.4 motor. But when I use the power gears even though his takes it off the line and may even beat it in like a 10' drag, mine catches up and would probably overtake him in like a 20' drag.

so i'll go from 4.6 seconds to go 0-10' to 3.2 seconds if I buy the pack form Z-Cars that comes with the 3.0 motor right?

You should...with the 3.0 engine Atomic Toys says you should drop to 3.0 sec in the 0-10' but mine seems to run about 3.2 seconds.

so, anyone know where i can get this upgrade thing?

Just use a bit motor. Z-car accessories are somewhat hard to find as I have experienced.
