Any videos of the engine running?

Are there exhaust options (headers with the normal drops) available?

Here are some More pictures of the new 178 by Gp. We got it on a stand today and are working on some videos.
The changes that were made made this engine made it one of the smoothest running larger two stroke engines I have ever ran.
The power also is amazing . We have been testing this Tillotson carb for a few months and it is a perfect match for the 178, the low and mid range is super smooth. Thanks Dan,Russ and Rob for your help.

The changes to the cylinders,crankcase,prop hub, reed angle and carburetor has made this engine a smooth running beast.

I tested a 30-13 wide falcon carbon on the stand with only a few ounces of fuel though the engine and was amazed amount thrust of prop rip on the ground .

I will be posting videos later in the week and get the weight and some rpm numbers as well.

Gp engine has more releases coming soon, thanks to the factory for hard work put into this engine...

Most powerful engine in it's class - are we talking the 170cc class ?
Where are the manufactures figures to back this claim ?

agree!
What defines a class these days anyway, there are plenty of engines out there with all different CC's!
