ok im looking for a lot of speed. Im just gonna be bashing. What engine will go the fastest? i want 200 dollars or less and if it could be in a rotary carb. that would be best. thanks for you help

OS .18 CV-R or TZ.

ok for the tz at a 50 20 gearing about how fast would it go in my xxx nt

Should get around 50 with insane torque. The .12 TZ should go faster and be more controllable though with not as much torque.

ok well do you know what engine would get me going around 55 60?

The .12 TZ would get you going fast. You would have to gear up though.

well i got an extra motor laying around running at 1.62hp and 44,00rpm..... and how much would i have to gear up for the xxx nt the lowest sur is a 50 that i can find

What engine is it? How many gallons?

I would get all 4 of the NT bells, 17, 18, 18, and 20t and experiment.

havent even touched it...... trinity .12 touring draked

That engien will make the xxxnt FLY especially on top speed.

haha.... at a 52 18 what would you expect at speed?

No idea... The only engine I have ever had in my NT is the mach .15re.

But since that is on onroad engine speeds should be fast!! Search youtube for videos of that engine.

havent really been able to find much

ok and just wondering will this be faster than the .12 tz?

Top-speed wise-probably.

ok and im new to slide carbs...... when i break the carb shuts all the way... is that ok will it shut the car off?

picco .26 jl red dot...just my $.02

I would adjust the idle needle to make a cresent shape when the engine is at idle. But I have never used a slide carb.

dang it
