Which .12 Motor for R40?

[rossb]

I saw a lot of super fast R40 cars at the HPI Challenge and I was wondering which motor those guys are running? I asked one guy and he just said "I am running a .12".

helloo

i know hara is running Nova Rossi NS3 Race it is 1.5 hp i think.
for what i hear this engine is hard to find.

you might also check out the team trinity sirio engines. there is a 12 legan engine that has 1.52 hp. www.teamtrinity.com

iam also getting the r40 soon.
iam already running the hpi pro 12R xs engine 1.35 hp 38000 rpm in my rs4 3ss. this engine is also shiped with the r40 as a package. it is rear exhaust also.
engine is made by hpi for the r40.

I've seen that engine in the HPI catalog and on Tower Hobbies. Can it compete with the racing .12 engines from OS, Sirio, and Nova Rossi?

How does the RS4 run with it? I was considering either the RS4 (Shaft) or R40 (belts).

I have had very good luck with my RB Concepts Rody V12. This was an awesome engine, but certainly not cheap. For a lot less money, the regular RB V12 is also a great engine and I have seen it run first hand. Alot of people seem to really like the NR S3 too. I think that there is a new mugen engine called the X12 also. Previous Mugen engines have been great, so I would assume the same for this one. I personally have not seen one though.

Hope that helps a bit.

it is very very fast. the engine is the same as this http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDUH6&P=0
novarossi engine. the especs are the same as well as the looks and the parts.
only the hpi is cheaper.
like i said the engine is very fast.
i ran it on the track and someone even mistaken it for a novarossi engine.
you wil need a different header for the rear exhaust.

if ya want a good engine for ya rs4 then i suggest this one.

We, my brother and I, have the Novarossi NS12S3A1, the Mugen X12 and the RB V12. All three engines are great engines but the power bands and snappiness are different eventhough they use the same block.

The Novarossi NS12S3A1 will cost you around $240 if you can find it. This engine is a real screamer and likes to stay in the higher revs for the power band. The same goes for the RB V12 3port ($220). The Mugen X12 is a MONSTER!

It has a longer stroke engine so the power is down low in the rpm band and up to the Mid-range. It's a real performer AND can outrun my Novarossi. Where my Novarossi tops out, the X12 is still pulling away from me. This engine is not cheap. MSRP says $400+. My brother got his for $300+. Also expect very low run times. It has a hard time hitting 5 mins when not tuned properly. It WILL take over a gallon to get it fully broken in. It has such a tight pinch and compression that a gallon is what it takes.

I liked the performance on this engine so much that I ordered one for myself.

The X12 mugen will be perfect for the r40 since that car is also pretty heavy & I got an extra one brand new in the seal selling it for $300 if your interested

I thought about an engine swap on my RS4 3 Evo. I looked at different possibilities with horsepower. The NS3 Race has like 1.5 hp and runs close to $300 as well as other engines out there that run close to $300 with less power. Then HPI makes the 18SS with 1.5 hp and tower sells it at about $150. I could buy two HPI 18SS engines at the cost of one NS3 Race with nearly same horsepower rated at. Now I know that the NS3 will most likely have better parts, but is the driver just as good to back it up? Some are and some are not. I saw some guys at the HPI Challenge that were running stock HPI mills and kicking cars with modifieds just because of their driving skills as well as their tuning ability.

 

[rossb]

I spoke with the HPI tech at the Challenge and he seemed to feel that running a race .12 would be a better move than running the 18ss. He said that the race .12 motors make as much power as the 18ss and the .18ss has fuel consumption issues.

 

[Diver6127]

You also have to factor in WHERE the power will be made in the powerband. Don't just go for the hp ratings, that doesn't tell the whole story. Race engine's are designed to make power in specific places in the powerband.

Remember, in this hobby the old saying "you get what you pay for" has real meaning behind it. The Novarossi NS12S3A1, the Mugen X12, NovaMega, RB ... they ALL use the same block. It's the internals that make the difference.

The Novarossi NS12S3A1 and the Mugen X12 blocks are identical as well as the #'s that they stand behind. BUT the X12 is a long stroke and the porting is a little bit different so the power characteristics are different. In a nutshell ... the X12 BLOWS my Novarossi out of the water. I would even bet my money that the X12 will blow that 18SS out of the water as well.

There is a weight issue as well as a CG issue. Top speed is important but the handeling is the money maker.

the weight of the car WITH OUT engine and electronics = 1,280g
the weight of the car WITH engine and electronics = 1,750g
the min weight for roar 1/10 rules is 1,725. so the car weights a 25 gram more then the what is allowed.

 

[710baby]

One quick thought you can't even compare a HPI engine to Mugen,rb,nova,etc like diver says you pay for what you get but you need to compare the quality of what you get for what you pay.
Hey petal I know the roar rules & it still is a heavy car & you forgot to add the weight of the transponder which might hit a totall of 30 grams overweight.
Besides nobody is winning A mains versus the other top manufacters

 

[petal2thametal]

and you forgot this is out of the box weight. put hopups on it and you even got a better car.
oh ya and 30/ 55 gram over the limit is very over weighted? . :nope:
your making it sound like the car is so damn heavy but its not.

at my track they all run serpents 1:10 and 1:8. gotta say iam not really impressed by it. other wise i would of had one.

 

[Remy]

I have a r-40 and I have the Mugen x12. I love it. I am looking for a rebuilt kit for it now because i plan to never upgrade lol. This is all i will ever need. YES it is that damn badass !!

My uncle runs a Navorossi 3 port turbo on his serpent 710 and my car seemed a bit faster. Granted he was having some tuning issues but I think if we are both having our best days I would be right there with him.

You can buy it here:

[petal2thametal]

ah thnx remy.

was looking for that. i can't seem to find this engine in holland.

 

[RatzoRC]

Her's my best guess on a mill. (from personal experince)

If your racing, Get the Sirio standard race. (roar leagal) 3 port.
If your not racing, Sirio Outlaw. (illegal) 5 port.
Both are .12

Thanks guys. I'm thinking about parking an R40 next to my Savage SS. HPI has treated me well.

Ross, which race did you win?

No, It doesn't seem like it's a lot of weight but to these little cars, it is.

As far as the serpents and being impressed, I was very impressed by a person at the track who not only drove his car well but also sets it up close to perfection. He won the ROAR1 regionals at R/C madness with his 710 and is also 710Baby's running partner.

Winning is 99% car 100% driver and this guy is proof of that.

Typo... I meant to say HPI has treated me well.
