These TPE engines are unreal! First time I rode one was a few months ago and after riding the first ski with 964 I immediately placed my order for one. Now that Daytona is over I've ridden 3 skis with the TPE964 in them now from 3 different owners with 3 different levels of tuning/performance setup. First one was Paul Lehr's -4.3 Superfreak with dual 49s, TL, B-pipe/TNT chamber, Solas 144 with 14/19 and it hit like a brick wall. So much power! Right from the crack of the throttle to whatever speed you can hang on for. This was a crazy powerful setup that's great for flatwater and puts many strokers to shame. After riding Paul's I was a little nervous of managing all that power in a small short hull for surf riding so I wanted to try some other setups for comparison. I rode Zimmys Blaster in Daytona which was a full length stock heavy pig of a hull. This engine threw the Blaster around like nothing and tried ripping out of my hands a few times while slashing waves WOT. This engine makes a ton of power yet is incredibly linear and will teach you to use throttle control. Third ski was another -4.3" Superfreak with a more basic setup: 48mm carbs B-pipe, 144 with pump stuffer and 13/18 or 14/19 prop. This engine makes amazing power with every setup I've tried. Bigger carbs and bigger pipes just add to the capabilities of this engine. ChadGnarly has a RRP pipe in his Blaster and made a significant difference in power over Zimmys boat. Unfortunately I didn't ride his ski but Zimmy is saving for that pipe now and everyone who compared said the same thing. This engine is amazing and it's power output can grow as your wallet does and can be used for all applications from flatwater freestyle to surf to rec riding. The price point is extremely impressive considering its power output when compared to much more expensive setups. If you don't believe what you read then just try one. Many people in Daytona that tried one had to buy one. I'm the type of person who doesn't believe a lot of things I read unless it's from enough reputable people I trust or if I try for myself but trust me, I have no reason to lie about this engine. I even waited till I rode enough setups that I knew it wasn't just 1 setup that made all that power from an engine builders tuning secrets masking any flaws.
I haven't ridden the 1105 since I'm no flatwater guy and have no need for that type of power but there's no need to drag your feet. Adding a 10mil crank to this engine is insane and I doubt most people could handle the power. Its for the diehards out there. This cylinder works!
