is the novarossi rx21clb/n a good engine i am thinking of putting it in my hong nor speed 9.5.
If its not good ill buy the novarossi p5

studysession

You have pics of your 9.5?

Most anything made by novarossi is better than most engines on the market.It is a brand can't go wrong with.

I agree with Study! Novarossi's are at the top of the food chain when it comes to aftermarket engines. One thing I will say though is that the P5 (along with the RB WS7II) is one of the most desireable engines for buggies. I don't know that I would have the P5 on my list as a throw in if the RX21 doesn't work.

The P5 is slightly more powerful than the RX21. If you're racing, and torque is your main concern, then go with the P5. It makes a lot of power down low. If your more concerned with top speed, the RX21 would be the way to go. The RX21 rev's higher makes more power in the upper RPM range. Either way, you'll end up with a top notch engine.

whats the price tag on the novarossi P5 and RX21. and where can you get them

dagass

The P5 will set you back about 250.00 to 300.00 depending on where you look. You can get it at both Brucknerhobbies.com and Nitrohouse.com. The RX21 is definitely more expensive at 350.00 to 400.00. Personally, I think it's a bit over the top in that it has a beefier crank case and the reciprocating assembly is balanced. It's a great engine if you have money to burn.

studysession

WOW! Expensive!@@[X(]

madmaniac

hmm thats strange the rx21clb/n is priced 270.00 while the p5 is more expensive 400.00[:-]
ill have no pics yet because i havent starting to build it.
there is no hurry because the weather isnt very good.

dagass

Madmaniac,

You are correct with the CLB pricing. My error, I re-read my info this morning and I pulled the specs from the R1WC instead of the CLB. Oops!! As for the P5, 400.00 is a bit steep. You should be able to get it for 250.00 to 300.00. The CLB looks to be a pretty good engine though.

studysession

CLB???

BUT..........


What your asking is "Is the ferrari 360 Modena a good car for my 23 year old?"

WRONG QUESTION!

If you dont know what novarossi is, please dont buy one!
I dont mean this as an insult! Really.

If you dont have the experience, novarossis are not gonna tolerate you. They are sensitive to tune, especially the 3 needle versions.

The advanced engines have the extra power.. but only in the hands of a professional! (aka someone like nitroaddict or i8tweety here on RCU)
Someone like me or you should stick to O.S
If you dont know how to tune, you'll waste your money, time and effort working on a high end engine. In the end all you'll have is sorrow!

How do I know? I learn the hard way ITs pretty bad when you have a $350 engine and a Hyper 8 port kicks your ass.

Ram's right. If you are an experienced racer, you should look at the high end novarossi, rossi, RB, etc. If you are a club racer, you need look no further than OS for power, reliability, longevity, and ease of tuning. Having a reliable powerplant allows you to focus on tuning your chassis and driving skills rather than your carburetor.

I agree with you guys i dont want to spend my money on something that im not even familar with. but heres the deal i blew my connecting rod in my kyosho gx21 today. its a kinda a peice anyway. so i need a motor with power and speed for racing. please give me some suggestions. money isnt a big problem its winter and i got time to save before spring.

madmaniac

the problem is that the exhaust that comes with the the hong nor speed 9.5 doesn´t fit the os 21rgp.
Ive had an ek4 mega force and a mad force so i can tune an engine pretty good.
is the cipolla x-power any good i can get it cheap.

studysession

cipolla x-power - Never heard of it. Have a link?

Are you looking for a pull start or non-pull start engine?

The non pull-start version of the OS RG comes with an exhaust adapter that will work with standard 1/8 scale headers. The pull start version doesn't come with the adapter as it interferes with the pull start (both are trying to occupy the same space on the back of the engine).



If you are looking for a pull start, you can purchase the header from duratrax for around $22.

Why don't you just compare the technical data?

The P5 is an unbelievable engine, fairly on-par with the WS7II in a different way, has more bottom end than the WS7II does but not as much top end however that can be maintained with a top end pipe. The P5 is your best deal if you can find one for $250, it varies from dealer to dealer from $250-300+, and go for the Novarossi version and not the Rex version. The model # is MUGPR21P5.

madmaniac

how hard is a novarossi engine to tune.
Isnt there any pullstart engines that will fit in my buggy
Is it easy to start an engine whit an starter box

studysession

During break in sometimes the pull start is easier. But over all YES the starter box is much easier for starting an engine. I have the OFNA 9.5 which is same thing as the Speed 9.5 since they are both made by Hong Nor - There are many pull start engines that will fit. Just do not know what's available to you in sweden. If they have the 9.5 then they should have the Force engines - figure few other brands.

Novarossi is a racing class engine. Most racers use starter boxes. If you bought a Hyper 21 - or an OS engine, you could easily get one with a pull start.

johnnyride

im gonna pay 300 dollars for an OS VZ-B. is it worth for racing or should i buy a better motor. i see everyone talking about these racing class motors for about the same price. i just want to know if i should go with the OS VZ-B for racing or should i get somethig differnt like a picco or siro etc... im open for suggestions thanks.

My Feedback: (1)

Good engines in the $250-300+ range:

Picco 0-1BP
Novarossi/Top SBK-01
Novarossi/Rex P5
RB WS7II
RB C5
CMB Raptor
O.S. VZ-B

I might have missed some others but they're all good, check them out on www.nitroreview.com . Not sure about the Sirio other than the $400+ pricetag.
