Default OS V-Spec Speed Worlds II

I am a Nova Rossi suporter, I really like there products. Recently has a chance to get a new OS Speed for a very nice price, had a race with it on a Buggy and really liked the way it performs, it's not a on/off switch like most Novas, a very easy engine to tune also. I have 2 MP9 one with a 367 and one with the speed, on the track I was faster with the speed, out "bashing" the 367 is a power house compared to the speed. Assuming the OS speed lasts more than a regular v-spec, it is a great race motor, but the retail price is very high.

On another note, I run the XZ .28 for two seasons (17 gallons) on original parts, but did fallow the manufactures 18% oil content. I can not find a minimum oil content for the Speed, only Nitro and a no warranty note.
I am running byrons 25/11, what kind of life should I expect from it?

First off, that 18% oil content thing comes from the old days where oil technology was nothing like it is today. Running 18% in today's oils is completely unnecessary, and will do more harm than good. All that excess oil does nothing but rob power, create heat and make tuning a nightmare. Anywhere between 9 and 12% oil is all that is needed with today's synthetics.

The OS speed is a great engine! If you treat it well, it will treat you well and last a long time. By treat it well, I mean using a high quality fuel(the fuel you are using fits this category), keeping the air filter fresh, and replacing some parts as needed. I like to change the bearings and rod in my speeds after break-in. I use TKO ceramic bearings. The replacement set of bearings and rod should last you through the life of the P/S. The nice thing about the speed is that the coated crank it uses is almost indestructible. Meaning it will last through several P/S sets if you want to rebuild it. A P/S set will last anywhere between 5 and 10 gallons. Maybe more if you treat it really well. So this engine can last a long time if you rebuild it a time or two.

As you have found, what makes this engine so magical is it's effortlessly smooth powerband. It is a very powerful, but smooth engine. It also gets amazing fuel mileage. Especially if you pair it with an OS 2060 pipe. Good luck with your speed.

A buddy of mine has 18 gallons on his Speed. He's replaced the rod and bearings and had it pinched twice now.

Like Jamminkrazy said, it's all about how you treat it.

You will get the best results with a OS T-2060 pipe or a Ninja EFRA2042 pipe (it's actually the same pipe, but with Ninja-logo instead). You will get awesome runtime, and you will have a smooth and powerfull powerband.

I have a Ninja engine, which is also an O.S. engine, and with the Ninja EFRA2042 pipe I get 12 minutes on a tank of fuel (145ml), and I can get it to go even longer.
The O.S. Speed II can get even better runtime than the Ninja.

In general the O.S. engines will last you a long time and treat you well, if you treat it well.

I have been running the speed engines for over a year now and I love them, more than enough power in a truggy and great runtime. They are just ballistic in a buggy. I have been running 30%/ 11% oil cold fusion fuel and I get well over 8 gallons on them. I do have to replace bearings every once in awhile but great little engines. IMO the OS 2060 pipe is the best match for the engine followed only by the OS 2050 in a truggy. I usually run the 2060 pipes on both but everyone likes something a little different. Great engine though.

I am using the OS 2050 on the buggy with the 6.5 restrictor and shimmed to 30%, but using the 25-11 byrons.
I do like the way this engine performs, thank you for the replies, I did notice that there is no thread on this motor, so lets keep it up.

It's all in the official os thread. But I agree this engine is so great it deserves it's own thread.

Really??? That is like one of the main focuses of the thread. Pretty much 50% at least of the talk on there is about the speed.
