Freestyle Affordable Power......... It's COMING

got to rip around on one of these for a few minutes. now, i strictly ride flatwater. a guy came out with a -4.3 freak. tpe SS with a TNT pipe and 49 full specs. im used to my bob so when i get on a new ski thats longer i look like a retard for about 5 minutes (which is about all the tray time i had) the power is always there, and climbs and climbs. IMO for the money, its totally worth it. I feel that a stroker motor would be better for my application of riding. riding this ski and then mcdogs 850 stroker back to back, i liked the stroker more. 2 totally different ski setups and its apples to oranges. i like the motor and love the design. i want to try a stroker to see what its about, i believe it would be more for me.
what 850 does mcdog have?

Old style ada billet cylinder 5 mil.

I liked the power of Paul's tpe ss motor. It felt very strong. Stronger than any ss motor i have ever tried. I cant wait to try the stroker version.

I think mine revs faster which is why Corey liked it better. Paul said the stroker motors will rev faster than ss. My ignition has more advance and a lighter flywheel too though. At least that was my interpretation. I get lost fast when discussing two stroke theory.

Shane, Gregg, Cory, Great riding with you all yesterday! Thank you for the hospitality!

It was really beneficial for me to have your SF / motor combo to use as a gauge for my work on this platform
So far I'm very happy with the initial performance on the TPE SS, But as we talked about, I'm just getting started.
cant wait to come back in a couple of weeks once I get it dialed in to compare ?


ski ya, Paul

a few of us feel the same way,I have a 6 mill stroker also that hits harder off bottom and mid,I like it better for multi purpose use,flat,wakes,surf. Surf has sucked this yr so most my riding has been in river. Keep in mind the tpe SS was developed from the very beginning to be a very linear torquey surf motor.The whole idea in surf is make smooth power that pulls forever and not get ragged out tired. If you ride flat only you just gotta go 10 mill.
That said,with the SS dial up the timing,get the top water screw on bpipe open enough on top,prop down and you can still pull plenty flat water tricks with a light weight hull
 
I have ridden Masterblaster's 6mil Able cylinder setup in his carbon SF, I have ridden a dialed DASA 8 mill 900 in a carbon SF. Based on what I have ridden to date, none of these motors can touch a dialed TPE 964SS in a carbon SF. I think there is some confusion on a snappy motor that hits and then its done compared to a motor that is making true power from the moment you pull the throttle.

McDog, from what I heard Paul is playing around with several different setups out there including trying different power valve springs and from his post it looks like he is still dialing it in. What prop are you running?
 
We are talking pump fuel at this point also.Makes no sense to run SS in flatwater to me,10 mill all the way.If you ride surf SS all the way.bases covered. No doubt the SS pv pulls longer than the non pv stroker,as it should. I wouldnt use that long speed pull outside 20 yrds though. the initial hit of the small strokers is just quicker,it doesnt sign off until im at a unusable speed anyway.The light weight 4 mill tpe sounds cool,but for $1000 crank might as well go 10 mill for flat water
Im using fast detunes on the 6 mill to make it surf usable,that would work good on the 10 mill for true dual purpose. take some water out of the top screw and pull the ball out of the jetworks valve,flood the wbox and it smooths right out and gives more linear pull up top

No doubt that Paul can still get more out of that motor and he is tinkering with all sorts of tuning aspects. The motor felt very strong through out the powerband.

Prop and pump and nozzle bore and cone size are just as important as anything else when tuning, maybe even more since it gets the power to the water. I run a skat 144 with a 14/19 prop and stubby cone. I needed to prop down when I switched to a powerfactor pipe but I had a 87mm nozzle to try switching out from my 85mm nozzle and it effectively did the same thing as switching props by unloading it. So 87mm nozzle on mine now.


I dont want to say what Paul was running. I never know what may be telling too much when discussing engine builder's or pro rider's setups so I will let him chime in if he wants.
 
I just put D-booster Novi 48s on my 950 Polaris from my first generation Novi 46s... I'm even more happy with this engine. It makes flat water fun and is amazing in the surf. Has power everywhere and I am confident I have more power than 900 Dasas running race gas and power factor pipes. I run a B-pipe, 175 psi, and 148 pump (and I need to go up on my pitch). The only thing it lacks is that initial punch that the high compression gives you, and I don't like that anyways. Erik built this engine last year for me and claims it was his initial experiment on what his current engine is. It has a 70mm stroke vice 68mm, and 93mm pistons instead of 95mm. Port timing is the same though, and port layout very similar.
Erik does very good work! Now if we can just keep him away from shiny objects, we'll all be good!

230 psi. On 4 parts 100ll to 1 part 93. Seems like it wouldnt work but no problems for a year so far. I dont do long wide open runs though.
 
mcdog,what comp you runnin?the stroker im speaking of is not super high comp..its pump gas

I would love to see what the TPE does on 230psi and race gas like McDog is running!!! right now mine is at 180, I think Paul is around the same. Torr, I thought you were running around 210 in your stroker setup?
 
little under 200,kinda the limit for straight pump fuel, Im also running tiny little 83 mill pistons and smaller 46 carbs to get 2 hour ride times. revs to the moon stupid fast,ask josh how fast he thought it was signing off pulling up chest high waves...dude went to the moon today.lol If your think you can even get a 95 mill piston to run on pump fuel at 200 psi, give er a whirl and see what happens.I cant remember where my tpe SS motor comp is at with the new dome profile,but i wouldnt feel safe pushing it to where the small stroker is on pump fuel....

mcdog has a completely diff setup runnin that comp and av fuel. Im not concerned with what a motor feels like on race gas for combo surf,river use.
almost every new SS billet motor ive rode felt good on crazy comp and race fuel,and reg smeg on pump fuel. and some beyond that really!

Anybody know if domes are available, or how compression changes are being done? I'd like to try a ss, but am running tl / pfp / 48 fs etc... At 5,000' elevation. I love the fact that a lot can be achieved within certain budgets, but I want to get my parts on one. Just not sure how it'll work? I ride 99% flat water and chase boats occasionally. Will ride surf maybe once a year at best. Suggestions?? I was all over the ss til the last couple days posts about differences between the hit from the ss to the stroker. I want to be flatwater flipping etc. I've done some off wakes, but am only getting 3/4+ with my current frankenstein 781ss off my own wake.

Thanks fellas.

there are couple dome profiles,not sure what max comp will be yet. If you ride flat water all the time,it makes no sense to me to go SS at all,10 mill all the way,it has way more capability for flatwater and easy to detune for a blue moon surf trip

You could go to the moon on a 701 with chest high waves, it doesn't mean you are making real power.
Phil said this thing hits better than his 900, and that's from a guy that knows his stuff. Calvin knows what he is doing, as does Erik, this cylinder has the best design in the market, period.

Torr, don't let your light weight hull fool you into believing that your motor makes real power. Your current motors are weak race setups, drop that 964 in your boat if you want to know what real power feels like! Lol

A few posts about stroker setups with less cc's on inferior designs "hitting harder" of the bottom on incomparable setups cannot sway the fact that the design and TRUE performance that these cylinders offer is anything but exceptional based on a well thought out design on proven technology. Apples to apples on any setups currently under discussion would be the 964 FTW... (compression, tuning,etc)...
