This is my Xenon R in a NTC3 car and I must say that the engine is top notch and VERY fast. No wonder I can't get a race at out local hangouts;).

A question for RB techs though. I have a friend that has a Xenon R and his conrod broke because the rear bearing let go. Fortunately it was only at idle when it stopped running. We took it apart and the block is fine as well as the sleeve, piston and crankshaft. It just needs a rear bearing and a conrod. I think that a ceramic bearing is the absolute way to go as with his motor going out like that has made me pull mine out and send it to Rick Brake of RBmods.net to port it more and install ceramic bearings. I also plan to purchase a new Alpha Xenon to compare it to my Kangaroo .21 as well. Thanks for a great engine.

hi guys, my fren just got an RB V12 3 port paired with the RB 2611 pipe. during break in ( followed the manual) all went well. after the 9 tank we started to lean it to get it to race tune. but there seems to be something wrong. the idle is not stable and the engine will over heat. after richin it back it will bogg. when leaning it back (in 1/8 turn the main needle) it still act the same. we r totally out of ideas. we try to look for leakage but there were none except some fuel near the carb.but we think that should be normal:rolleyes::rolleyes:

Guy,
This is what I am here for, support! I am an open book, and whatever knowledge I have I am more than glad to pass off. It was fun pitting with you and Vincent and the rest of the 301 boys. See you guys this weekend.

Don't sweat the other thing, even though I am :cry: inside. LOL
Just kidding racing is racing and occasionally things like that happen. We both handled it in style. After all you are my Teammate and I was glad to see you advance regardless of the circumstances.

Jamie i had lots of fun with you guy and vj at the us open they better watch out now we have a potent team my r3 was a missle and hopefully my alpha is the same

idk if the ceramic bearing is the way to go i have a murnan xenon r without the ceramic and have had no problems with it and it is just as fast as the onres with the caramic bearing:nod:

RB engines powered the top two drivers at the first race of our season at 301 Raceway!!!

Congrats to Jamie Corrado on his TQ and thanks for all the track-side support.

The word is getting out on these powerplants. :nod:

MA Racer,
We have been running the Alphas for a few weeks now. It has been a bit of a learning curve with the new carb. but things have been going very well. The engines are super fast and run-time hasn't been a problem. We haven't had any issues. We have tested pipes, shims, ect. and thumbs up!:tire:

ma racer 04-29-2008 12:51 PM

Thanks Jamie,
I'm going to pick one up for my local scene and then another for the GLC. Any suggestions for the engine? pipes, plugs, headers etc. Here in Houston we race on a relatively short track with mucho 180 degree turns, but as I begin to travel ie-GLC etc. the motor will want to stretch it's legs a bit more.
Again, thanks Jamie

I know that I am not Jaime, but try to gear around 7.5 on 1st gear and 5.1 on 2nd gear. That is if you have good traction. If not good traction go to around 7.0 to 7.2 on first.
