Default Building my NTC3 and bought a MUGEN MT.12 motor for my NTC3..good choice? need advise

Sup fellow nitro heads

still sorta new in the nitro scene and i just picked up a NTC3 wich was the older kit #2030 and im am now hooked on nitro cars!!!

Ive done all sorts of goodies so far with
AE-Factory Team & K-Factory parts to bring it up to date and beef it up including the v.2 rear suspension upgrade

My concern is.........
Did i make a good choice in buying the MUGEN MT-.12 SG crank turbo motor? (slide carb)

i hear a bunch of different things from certain people like Yes its a great motor with the right combo of parts and others say that it's a decent motor and should have invested more and bought a Novarossi NS-12 motor?

Is anyone using this motor and are u happy with it?

How fast would u rate this and guestimate the MPH it's capable of?

Is there any tricks or mods to make this motor make more power?

Any input with anyone running this motor would be great.

my friend was running a 1.0-HP Rex/Novarossi side exhaust motor on one of his older nitro cars with a CVEC pipe and that was moving pretty quick already so considring this MUGEN motor has 1.15-HP and rear exhaust i would assume it would run alot better?

So far the set up that goes along with the drivetrain is:
AE Large bore foam air filter
AE 3-shoe clutch set up with stiffer (copper) clutch springs
AE lightened clutch bell
Factory Team Lightened 2-Speed one way hub
Factory Team Gearing (54/48 & 21/27)
Using front/rear ball diff set up with factory settings
Werks Racing Tuned 2-Chamber Pipe
K-Factory harcd coated aluminum front input shaft cup and brake cup.
k-Factory LCG tank (if it matters)

I have not ran the car yet and the motor is still new never been ran.
still getting the other things to get her fired up like starter box, gas and other nic-nacs

What brand gas and % would u guys rec.?

for my electronics i bought the following:
KO-PROPO EX-1 Mars-R FM 3-channel radio with the KR-301F micro reciever
KO-PROPO PS-2173 "Hi-Speed" servo for steering
KO-PROPO PS-2174 "Hi-Torque" servo for throttle/brake

I'm not sure if i will be running at any local tracks or not but mainly i will be doing some parking lot racing with some buddies
Any input/opinons/suggestions would be great on my set up!

The MT 12 is a very strong and reliable motor with pretty good power but it is 2 generations old so it is not as fast as the NS12's. The main area that the NS will show it up is in the top end. The MT12 is easy to tune and very user frinedly so I think it was a good purchase and later on if u decide u want to race or get more speed then get another engine.

With your friends CX12 (I assume), the MT12 should blow it away.

On the max speed that all depends on gearing, size of tyres and other factors.

For fuel i'm not sure what brands are available to you, sometimes that will determine what you run. For Nitro content I always feel 16% Nitro is a good place to start, the higher the Nitro % the faster your engine will be but the life of the engine will be shortened. If you go 20-30% you will also probably need to re-shim the engine too.

Hope this helps

20% is what most people run when they are racing. The MT-12 is a great motor. I've had 3. If you're not racing you won't notice the difference between the MT-12 and the newer generation NS motors. Even if you do race, the difference will only show itself on medium to large tracks where the straights are long.

Thanx for the input guys!
Well I'm glad to hear that I didn't make a bad choice.
Is there any other things you guys would rec. To make this motor more petent?

What about my pipe choice?
Anyone using the Werks Racing pipe?
One of the biggest LHS here in the Bay Area rec. This pipe.

Question for "spawn"
I have seen those RDlogics pipes and they look pretty impressive.
Now since the mugen mt.12 is a turbo motor is that the reason why u rec. The RD turbo pipe?

I will snap some pix on the digi cam and show my set up.

Thanx again for the input

The MT12 is a great engine and with the right modifications will run with any engine out there.

That makes feel much better!
I heard that from one of the guys at the L.H.S

Are any of u guys running the one-way front diff?
I hear that u loose a lot of the brakes but good for exit speeds.

Would that make it faster on the straights vs the ball diff or just mainly turns?

Sorry for so many questions guys but I'm just trying to get some actual info from people who actually run these set ups.

The MT12 is a good engine, I wouldn't worry about the power as to most of the new motors overpower these cars in the first place. Another plus to a slightly lower (still good power) is that it will be more driveable through the technical sections of the track.

Yes, with a front one-way you lose alot of brakes (only the rear wheels brake). A front one-way acts like a very loose diff off power and a solid diff on power. When on power the front wheels will try to pull the back end in the direction of where the wheels are pointing. This allows when midcorner to corner exit to be able to apply power sooner and harder than a standard diff.

On a perfect straightaway a front one-way and diff will be the same, but that is only on a perfect straightaway. In real life, the diff will be slightly (almost unnoticeable) slower due to imperfections of the track and weight of the diff compared with a front one-way.

My advice, is try both ways and see which way you like. If you find you don't use brakes - go with the front one-way. If you find yourself going deep into the corners and braking late, go with the ball diff.

Sorry it's so long, but hope it helps.

Btw..you might want to try a search for this type of stuff as there is alot of good info on this forum.
