Top gun 777,what does BRB mean
BRB stand for Berrilium Bronze ( Berrilium Copper). There are many different types and only one type is suitable in our application. We use BRB for last 25 years instead of Brass. It has so much benefits to compare Regular ABC constraction. It is much more expensive then Brass and it is realy hard to work with, but benefits are so great, so we do only BRB.

Ron,

the Euro is steadily climbing (damned Europeans) which unfortunately means that all the Italian based engines are going up in price.

RB Concepts just raised their prices considerably.

For the prices stated below, I would think those are retail prices though.

From what i have heard, JP prices are going up coz they are now having their own engines made....not modifying novarossi engines anymore...

Hi Schrijver99,

They should be the same Nova Based motors, except for the following:

- The FX Line will be available in ABC and/or AAC Format.
- It will no longer have the Nova Name on it as, just like
snoopy said, Novarossi will no longer allow an independent
modifier to work on their motors. The motors will therefore
show the JP logo where it used to show PR-21 or PT-21 or SP-21.

FYI, the base motor is still manufactured by Novarossi for JP Racing.

And this is still apart from the new Exa Line...

Yes, and the FX .12 engine is based on the new Mugen X12 engine, but with JP logos.
Mugen and Jp work together.

Really all Nova based engines have the same bore(13.80) and stroke(14.00), which makes them technically long stroke engines, but in the past there were to types; long rod(Mugen MT2 and REX MT12),and short rod (all the rest of Nova based engines), but with same bore and stroke.
Now a days all of the Nova based engines are short conrod, but still with same bore and stroke, except for the new Novarossi RRL3, which is really longer in stroke(14.25) and smaller in bore(13.70) than all of the rest Nova based engines.
The old Mugen MT12 was a long conrod engine, but I'm not sure if the new X12 and it's JP version FX12 have gone back to long conrod, I think they are short conrod.

Yeh, I wouldn't call RRL3 much longer strock, it just about1.25% longer which doesn't make real difference. I have never open any of them, but will be no surprize if we will find out their rod is longer then usual. Also real diameter on regular Novas engines is 13.76 mm and its top area is about 0.8 % bigger then on RRL3. It still the same engine. Actualy it is very good set up from my understanding 13.76 x 14. For our application besecaly it is the best ( closest to squire).

hi Edward and afm,

I think Nova is found something, coz the conrod is the same with NS/RS base (07601 Comp. conrod) so the different will be in big end (circ. stroke). The crankcase is about 2-3mm higher than NS.

I had a chance to open the sleeve and the exhaust port is wide open already but short on height, maybe as a compensation to longer crank timing.
Thicker sleeve wall.

Im no engine expert but when I see the crank timing, they definetely looking for torque. Im comparing with Max modded NS base crankshaft.
The inlet crank port is slanted already. This is where the modifiers put a "red" resin on it.

First I was having a doubt about this engine durability, the compression ratio is much higher than normal NS but Mike Swauger is proove it in 40 minutes and 40% nitro.
For 1 race it seems no problem, in longer terms..?? who knows..
