The O.S. T-2080 pipe is the best for the engine if it's available. If you run a Novarossi pipe, run the 2015.

I usually run at 105deg C ideally, max at 110deg C.
The engine can take punishment up to 125deg C, but you will lose considerable power at this range although better fuel consumption.

Thanks for the response. I ve been running it below 110 deg C....was just wondering if I shud be running it higher,as I think the Novas do run at a higher temp.


Once again, Thanks!

I don't recommend nova plugs on OS engines. Tried it before and the seating of the turbo cone doesn't sit flush in the OS top plate.

Hi Guys,

I just bought OS Speed 21XZ-R and the 2080 tune pipe for my Serpent GT car. Now I realised the 2080 manifold is not pointing correctly. Any of you guys using this engine on the GT car? Do I need to purchase the offroad manifold, ie the 2060 manifold and use it with the 2080 silencer?

thanks in advance

I have bought an used car with this engine. It has runned about 4 liters so I want to replace the rod but the OS onroad is not sold and supported that well in the Netherlands.

Searching on the partnumber I also come to the rod of a VZB buggy engine which seems to be the same. Is this true? I know some shops over here selling OS offroad engines.

Hi experts

Here in north europe the onroad season is pretty much over, and the gear is cleaned and prepared for next season spring 2013.

In 2013 we are switching from 25 to 16 % nitro.

How am I going to change the headshimming on my Speed 21 XZ-R ... from the standard 0.3 mm to ?

And do I have to change to an other plug (have been using the standard RP7 with 25% nitro) because of the lower cooling of the 16% nitro ... the cooler plug RP8

Best wishes; Jens

Hi Jens,

I'd just try the engine as it is with the 16%.
