XRAY - Model racing cars

My personal choice would either be the Rb C6 BBT7 (comes with a turbo button head) + 2045 pipe or the Ninja .21 and Ninja Fast-Link pipe.

I've only owned RB's before I bought the Ninja, but am very impressed with it. Good fuel consumption and very well made (only downside with the pipe is that it is very short so you either need to make your own pipe support (out of 2.5mm wire) or use a gmk spring thing.

IMOP i am using the RB C6 T7 with a jammin jp3 pipe

And what yiou can say about this engine http://www.mlcollari.com/engines_off_uk.asp
??

I would go with the 367. I love the fact that it comes as a complete package. I actually just fired mine up for the first time about 15 min ago and it sounds pretty good. Now if only my starter box battery didn't die!

Ever thought of the Max M5B MF+ Nova long smooth flow header + Novarossi 9886 or MAx 2017 pipe combo? Brutal power throughout the powerband.

Trick looking sleeve in that 367, been contemplating one. 2 gallon break in before they shine I read.

Still lovin the Maxpower M5B, one of the best engines I have owned. Recently did some racer secrets to make it even better.

I´m running OS VZ-B V-spec with the red 8mm carb restrictor with TTR EFRA 2039 in my XT8
and the power just keeps on coming. A very smooth powerband. Runtime is atleast 9 min+.
Another plus is that the V-spec is really cheap nowadays, atleast here in Sweden.

I may have missed it, but is this for buggy or truggy???

My experiences with some of the mills you mentioned:

Vspec and 2050 pipe - great power, great runtime, easy to tune

OS Speed - the fastest motor I have seen at the track..period

Nova 367 - no personal experience with this one, but Bess just did a review of it and it sounds perfect for buggy

Ninja - I loved mine - I used a 53 pipe and got almost 10 minutes a tank with very smooth power - very easy to be fast with this engine

RB C6BB - use 2045 pipe or SW 053 pipe - very strong engine and good runtime

Max Power M5 - my new favorite engine. I have only run this in buggy, but it is sitting in the XT8 right now and I will try it out Friday...I am sure it will work well, as it is similar to the Ninja - very smooth, but more power everwhere then the Ninja (runtime not as long though)

I want engine it ro buggy.

Two years ago I have xray XB8r(great buggy thats why i decided to buy next xray) with RB WS7 II and this angine is very nice. Easy to tuneand good power. But now I would like to buy something stronger and faster. I have to buy engine on www.rcmart.com or www.rc-mushroom.com good price and ships intarnationals without taxes. I woud like the best engine for the price. I can spend about 500$ on engine and pipe.

Do the jp pipes not fit the ERFA rules?


Can someone explain????

EFRA rules state that racers MUST use 3 chambered tuned pipes in accordance to noise regulations in Europe.

JP-1 and 2 are two chambered pipes while JP-3 has 3. Unfortunately it does not perform well with the RB C6BB.

ahhhhh....

Thanks Richmond for the information on the rules. I had no idea....

JP-3 was widely used during the Worlds in Jakarta which is run under EFRA regulations.
