The only thing permanent is change
For as long as most of us can remember, the U.S. automobile business has had cycles. Whenever there was a down cycle, you knew you had to hang in there, and before long, things would come back to normal. And then you would see the cycle head upward again. It's not going to be that simple this time Keith Crain is publisher and editorial director of Automotive News. ...

Summit 800 2 Stroke

I have recently put 3 grooves in the head of my 2005 Summit 800 2 stroke and am thoroughly impressed with the amount of power increase and more specifically with the added torque that I got out of the engine. I was lucky enough to know Ken Podgurney who is a local in Whitecourt, Alberta and he has used the groove technology for 2 years now in many types of vehicles. He helped me(more like I helped him) to first convince me and then to actually put the grooves in the head of my snowmobile. I have not driven it enough yet to realize the fuel savings which I am sure will come but am very happy with the results of the increased power and torque. Awesome!

I read on this forum that grooves should have .10" -.15" wide! I want to khow how deep they should be?

I have the same type of engine and the squish band is really wide, around 65% of the total surface area.

I will keep in touch within 2 weeks with pictures and dyno test.

Thanks

I usually taper the groove from about 0.005" at the gasket surface to as much as 0.075" at the CC. I follow a 5* taper. On extremely large squish pads, like the SBC, I'll follow a flat line groove until I get close to the gasket then taper it up. The SBC set I did was about 0.040".
