twinn engine nitro

[nitrosteve]

i really want to build a twin engine nitro but dont know how

I did it to a TMaxx a few years ago. Kinda nifty project but it requires a lot of $$ to make it usable. To be quite honest with ya, the only way I'd do another multi engine vehicle is if it was a full custom project. I don't recommend multi engine conversions.

I have a hard enough time tuning one lol. i couldnt imagine two. Seems like they might work against each other if they arent tuned right.

 

[Lessen]

this is true... basically, if they are not tuned closely you will eat clutch shoes.. and that's just the damage that you can see.

 

[Suicide]

if you want that power just buy a race tuned motor. they are probably the same cost as what you would spend on a twin engine rig

 

[solly69]

a twin engine rig would look pretty good.... and well if Rolex was to make 1 tuning wouldnt be a problem because he doesn't drive them anyways

I just sold mine, theres a thread somewhere around here still, DONT DO IT!!!! You will spend an hour (once you get good at it) tuning the engines together, then after 2 tanks, which go quick, one is dragging again, I admit it was the funnest RC I have ever been anywhere around when it was dialed in perfect, BUT I was ALWAYS tuning, and tuning, and tuning just for mabye 20 min. of run time then back to tuning. you get crazy torque, alot more than you can get from a bigger engine but unless you are doing pulls, it is not worth it at all.

The sound is pretty sweet as well

BOOYA!!!

One of my all time favorite t-maxx vids. Sounds like a swarm of bees!

As for your "want" to have a twin engine rig, NE has a savage kit: http://www.neweramodels.com/item.cgi?session_id=&part_id=1800
Don't know anything about it though.

do both engines run on one tranny?

do both engines run on one tranny?

yeah it dose

i realy wouldnt do it unless your doing pulls or its gona be a shelf queen because they will cause such a problem because well its double everything like double the tuning wich would be hard as hell to keep them in tune plus the its going to cost a bunch dto do this

 

[solly69]

nice vid

 

[surgemaster1970]

Heres a few pics of a Sirio V-twin design that utilizes a single carb to feed this beauty that would accent any project nicely and would eliminate alot of problems like dual tanks,dual carb linkage setups,tuning probs and killed clutches

 

[Racer 1966]

SAWEET!! I'll take one with roto start please!

 

[neobart]

There's no way that engine is more that an elaborate thought experiment. No chance in hell it'll ever be able to run.

 

[Racer 1966]

Why do you think it can't run?

 

[neobart]

The two pistons would have to run out of sync, so what ever piston is first gets all the juice from the crankcase. But hey maybe they found a way to push 5 strokes through a 2 stroke crankcase.

 

[Metalhead Matt]

V twin 2 stroke snowmobiles have been around for years. Same concept, isn't it? I don't understand why it wouldn't run if the 2 pistons rotated 180 degrees apart. While one is expending burnt fuel the other one would be taking in fresh, wouldn't it?

 

[olds97_lss]

I would think so as well as long as they ran 180 degrees from each other... that would be one cool sounding exhaust note! 30K RPM's would sound like 60K!

 

[Lessen]

That is a beautiful engine. I've always envisioned a way of just using a single carb for two engines but that'll pretty much do it

I'm not sure what the heck you are talking about. I don't see any reason why the engine would not run properly. It all comes down to the design of the crankshaft and how the air passes from carb to cylinder. I sort of think you're assuming that one engine is getting air at 0* when the crank is lined up (traditionally) with that cylinder and that the other engine is getting air at 90*. I would think that that type of setup would be improper. It makes sense to me that the crankshaft in that engine probably distributes air to one cylinder at -90* rotation and to the other cylinder at +90* rotation. This way the cylinders are receiving air from the carb at the exact opposite angle of crankshaft revolution.

Guess this one doesn't really count since it appears to be 4 cycle...
