I would stay with a stock engine. A modified engine in going to be a little more sensitive to tuning changes. Get a nice stock engine. Remember slower is faster. learn how to drive and tune slower engine first.

I'd say if you are getting beat on the straight then the only answer is a Murnan RB. There are stupid fast yet still very very easy to tune. You really can't go wrong with one of these motors!

hey guys, dont want to be rude or anything but i cant seem to figure out how if u mod an engine to have more power and torque but yet be more fuel econmic

Thats not 100% true. All my engines are modded, some are modded by Murnan and they make the same runtime as the rest of the guys.

Some modifications just improve efficiency. If they improve efficiency it means it is getting more power for less consumption!

Bobby Congrats & the P.R. Cup & also tho the Murnan Team
See ya @ the Winternats if your coming down

Also with better spool up time. You can grab less throttle; and still get from corner to corner faster.

That is correct, with the power increase it takes less throttle to go the same distance. That is one way runtime is better.
Another thing that helps runtime without power loss is the way my modified engines burn the fuel. More of the fuel is being burned and not wasted. Mostly due to the change in the shape of the heads, cranks, weights, and a few secrets...

Perhaps there's something to be said about the racer in this matter. A good racing buddy of mine is a modified RB runner, the engine is remarkable, having said this..

As too is his attention to detail on all other aspects of his car, it's not the average "Joe" that would invest in an modified engine of this calibre so free roll of a chassis and rotating mass and inertia comes into play. Attention to bearings, altitude above sea level, car setup, clutch slip, tyre slip all equate to power to ground and overall fuel efficiency.

He gave me an "old" one made from old spare parts, after replacing rear bearing and O-rings the old Murnan RB still rocks for it's age and all I can say is ... they are AWESOME ENGINES!!!

Hi Uriah,

Can you modify a RB T9 Stock version and make it exactly same like an M3, except the new cooling head?

has anyone here tried the moded 09 Kangaroo?need some reviews coz keen on ordering one

am

Hi.

I am an offroad driver and have used the Nova +4 this seasson. I was wonderring how your engine is to drive compared to a stock +4 engine? Is it the same smooth engine with higher rpm? Are the fuel consumption the same on the modified engine? etc...

Thank you so much for your help and time

No. It will be pretty close though.

The engine has tons of torque, and good top speed. The engine will run with the best of engines. The Kangaroo is a perfect for those small to medium size tracks. The engine has more bottom end, and slightly less top end than engines like the mod 35+21, Flash, C9.

I hope this helps.

Hi. The modified +4 feels more aggressive out of the corners, with a lot more top speed than stock. The modified +4 gets similar runtime as the stock engine, with more power. With my modified +4 you can run a smaller ventury, and get the same power as the stock one with much better runtimes. Or you can use the same ventury, and roast your tires off.

I recommend the 5.4mm ventury from a .12 engine to get the most runtime. Most of my off road team drivers are using less nitro, smaller venturies, and still have plenty of power for most off road tracks. For Truggy I use a 6, or 7mm insert. You can also use the 5.4mm in truggy. Talk about extreme runtimes!
