Notice he said top speed. With the right tune,gearing, and pipe the eagle.12 revs higher then any .12 on the market. Jp motors are top in motors the timing is set up very high it is proven. That is also way the bottom end is so low. Overall the motors to get would be the xxl3b, Murnan rbm3 very fast and the make runtime. You have to gear the jps lower so they can get into the meat of there powerbands. Also the +12cst piston and sleeve will fit the eagle tl3-t. The power comes from the crank anyway but if you really want the fastest .12 motor than the +12cst Murnan drag mod is the motor for you. It won't last long if you drive it on the track but it will be the fastest 3 mins of your life then it's time to refuel.

18tz only has about 30000 rpm, may not have good top speed if used in 1:10 car

Could be, but it has loads of torque so you can use the most heavy gearing possible to gain speed.

By the way, th 18TZ is rated more:

The printed numbers are the last specs uou must believe. Those numbers are most of the time simply calculated or just a fairytale.

Usere experiences and dynotests are only real arguements to get one or not.
(what ever happened with the dyno database?)

Hi,

How is the stock RB R3 compared to Novarossi Plus 12 3SCT when it comes to top speed? Also, is the torque on the stock R3 any good?

Would you say that 380 USD is a good price for this engine?

Or would you rather buy the Novarossi 3SCT?

Regards,
Serpent fan

I can get the RB R3 for 370 USD , including pipe + 2 manifolds, so it's a bit cheaper than the 353.

But I was wondering which one of the two mentioned you would recommend, and why? I have heard that the R3 is a pretty good engine (I'm thinking about the stock version)

Regards,
Serpent fan

There were Rb R3s and R3 RCs in our nationals and I was able to post faster laptimes from both of them with a Novarossi Plus 12-3SCT. But this doesnt mean RB engines were slower. I hope you get what I mean.

380$ for a R3 is expensive. I can find a T9 with a 2604 pipe and manifolt for about 220 euros.
