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

Ma Racer,
Give me a bit more info:
-elevation
-brand of fuel being used
-clutch shoe/spring
-high/low bite track
ect.
Thanks

Let's see here:
Houston, elevation = from 120 to 345 ft. above sea level
Brand of fuel = Rocket Science 30% or Tornado 25%
I do typically use the Rocket Science though.
Just experimenting with the Tornado
Clutch shoe goes from Mugen grey to red to yellow
depending on traction
Normal traction at the local track is low to medium. Only
when we have a larger than club race do we see
the good stuff.
Thanks for the input!!!!

I thought i'd post my impression of the zenon r on here. I broke it in with a new break in process posted on th rb forum. I changed the carb to one i had from a 35 plus21 i blew up and this engine is by far the fastest i've ever ran. I was running a 2018 pipe with a # 6 plug. 30% fuel with an extra .1 mm shim. I love rb engines!

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




the above problem has been rectified. we put some gasket sealer between the carby neck and the crankase , and everything is just fine...idle well, no overheating and last a full day's race. thanks

hello ghettoteacher
sorry for the long delay in answering your question.
the tm928 engine has been discontinued and has been repalced by the RT.
The RT has a beefed up crankcase compared to the tm928 and has a standard plug head button supplied with the engine now.
The tm928 was and still is a great engine, but has soooooooo much power that lots of people have complained that it tears up their cars drivetrain and that the turbo plug made it sensitive to tune when it gets warm outside.
The RT has been refined to come with the standard plug button, the new L2G style head and the beefed up block. The engine is the best balance of power and reliability for the guys that want tons of power in their monster trucks.
We dont recommend the tm928 or the RT engine for buggies or truggies, its just too hard on the kits and doesnt get as good a run time compared to a C6 L2G
hope that helps

Jamie/Other experience RB engine owners - I'm getting an 8th buggy soon and am in debate between two RB engines and also a Novarossi. Is there is significant different between the RB S7 L2G vs the RB S5 L2s? Is it just that one is a 5 port and the other is 7 port? If so then the S7 isn't worth the extra $40 spending no? For the price of the S7 at my LHS they also have a Nova RX21 P5 and was wondering of the overall performance for the two primarily which is more consistent. Surely both are powerful, I know that.

RB Guys,
Good info on the TM928. I've got a TM728 in my Savage that may need a new p/s/r set. Was this engine discontinued as well? If so, what would you recommend in it's place to haul that heavy beast along?

How it comes, INSBOX filter do not fits on R3? Is it common thing or am i missing something?
Tried to put on standart mugen onroad foam filter without insbox and it dosnt fit as well.
Are there any special RB filters, that should be used? By EFRA rules insbox is a must, so i would like to know how to fit that thing on.

What up dude? Hope all is well.
You ready for your Regional race this weekend? I'm sure you will do well.

We have an extractor for every engine bearing size out there and also an all in one unit. Give Kevin a call, he can order it for you.

Filter issue is something i wasnt ready for, when paying 400$+ for it.
Situation seems to be odd. Product itself looks a good quality, but the fact that normal standart INSBOX filter doesnt fit is something im not happy with.
As RBproducts company is located in Europe (France), no one really have noticed that its problematic to use it within EFRA rules???
