Thanks desotoracing!

Does anyone know another choice for exhaust pipe and header for rb t9 Murnan modified seems that most hobby shop are out of the 2668 rb exhaust .I was told that the reds exhaust pipe and header would work 2669. Please can I get some feedback thanks.

The novarossi 2660 with 41016 header works very well.

Hipex 2669evo2 or reds 2669. For the manifold go for a C+ if you have a normal track or buy a M+ if you race on short tracks.

Fellas quick question, for you motor gurus, Can I run 20% thru my RB T11 rc in stock form? Or do i have to add a shim to the head? im in the bay Area 70-100 degrees....If I do run 20% what are signs that would say add a shim!!

I guess that question was to hard!

Here's another, is it possible to add a shim to the head to gain runtime?

I run the same engine. Byrons 20% 12% oil. It runs great. Never any detonation. I would add more fuel line or a Kyosho fuel filter to increase run time...

it will help a bit with run time and rpm,but will reduce some torque,i use the clutch setting to gain back the torque.

Add .10mm of shims. This will allow you to get the most out of the engine on 20%.

You dont have to add the shim, but it will allow you to lean the engine more. It is also easier on glowplugs to add the shim.

hay guys just wonting to know is the tXr really worth the extra $100 or is the TX good enough as iam looking to buy 2 engines at once. i see amain have them in the combo but to buy the txr in the combo it means the pipe is like $80 more.

so realy i would like to know if i would regret buying the tx cause the txr is that much better? i currently run a nova keep on so wich ever is the closest to that

Txr is a much better engine than the tx one ...it is worth the money difference

Thank you all for the info, will add the .10

Anyone know where I could get a piston and sleeve for a v12 rody? I believe the part number is 1700-0036r?

I searched the part# you posted and nothing came up. Do you have a different # by any chance?

I got that off rb manuals they have online. I don't really know the exact motor I have as I got it used. Is there any way to tell? There is a number I graves on the side of the motor mount
