Have anyone tried the shark 9? What do you think of it?

I have ran the Shark9 a little bit, have not actually raced with it yet because of the snow. The little I did drive the Shark it seems like it has great power for my buggy, and is supposed to get better fuel mileage than the C6.

The engine ran flawless and I was getting about 9mins a tank so far with a THS pipe. I finished 6th out of 10 in the a-main. This engine is the best engine for the price by far. I am going to get a Rally 9 next. I hope it is half the engine the K9 is. reo raceway puts on some really good races. Thanks Jay

I will have to try this engine for the 229 price. i mean you can't beat these new engine for the 230 price range. I know I will never buy a used engine again considering I can get good engine for cheap. I know I will never buy a OS over a rb. This is my 4th rb engine and just a good as the first one

I have found I like the way the #5 turbo plug works best in my engines. As for the LSN, I wouldn't say they like to be lean you just want to make sure the LSN is tuned so that your engine isn't loading up with fuel while it sits and idles. Once tuned good you should be able to let the car sit still for a good 5 seconds then pull the throttle and the car should accelerate well without having to clean out a bunch of extra fuel first.

Also, generally you don't want to see any air bubbles in your fuel lines as these will cause you a lot of tuning issues.
