Custom/Hybrid bottom end

[Byeai]

I'm not sure on the jets. I know the carbs are tuned well.

If you were in Florida I'd let you ride amandas

The only thing that gets me is my buddy had an xscream 840 61x based motor with a solas 144 and a b pipe it hit way harder on the bottom than my 898.

I hate that

You should be running ATP Flame TS or MSD TL. Why have all the goodies and a "safe" ignition?

That's a big pump to turn. TL and race gas domes are prob what you need.

 

[Byeai]

That's exactly what you need ^^^^^

I'm running a stock 760 with a pfp tl and setback 155 running the 7/14 prop for reference reduction nozzle is at 92.5 mm and it works great. I think your way under proped what's your reduction nozzle size at 86mm my ski would not even move. With that 898 I would be thinking 10/17 - 11-17 but I'm sure having total loss makes a significant difference

Reduction nozzle I'm running atm is 90 mm And it's paper thin don't think I can go any larger. Nozzle is paired up with the Xscream smallest pump cone.

Php 898 should be more than enough. But you definitely need TL on it. I rode a php 898 with pfp , TL 155 but It was on a carbon circus . It had more bottom end than my 1100 dasa. But maybe the hull had alot to do with it.

This.... Tim has had an issue with his particular setup for a while. The prop that we recommended to him was for a 155 mag pump. Well he ran a stock 155 and couldn't figure out why it didn't work. I heard later he was using some older non set back from a race ski. The circus Jr freestyle rode only had av gas compression, is very comparable in size to Tim's brawler and rips off multiple flips with ease. Bottom line is if a little 61x based motor is hitting harder than it you have a problem. Everyone who has worked on setting up a ski like this knows that if one thing is out of line it can take down the whole setup...the other issue is no matter how much Tim wishes it we can't always diagnose a setup problem from 800miles away over the phone. The motor is always the first and easiest place to blame. All of us running 155 setback mags with our 898s are rippin over the same original prop as you had with ease. If you can't there is something wrong with your build somewhere.

Here's a pic taken yesterday of my fat 240 lb ass on Zacks Circus. Shows the 898 has plenty of motor. Proper building is everything in an aftermarket ski. We test everything to make sure our customers get the best! Hope you can get it dialed Tim.

Why don't you help instead of "mine works idk what's wrong with yours".

If zack set up your carbs your fine on the jetting but why not run total loss and high compression race gas done if you want extra hit I don't mind helping with the setup but I don't have the 155 pump on our 898

I was saying how the 898 works and is plenty strong to pull the pump. I don't do the tuning, that is Zack and he has helped Tim and will continue to I'm sure.

And it's not my ski either. Mine has yet to be built.

 

[102nd7]

Zach I never once said there wasa problem with the motor. All I said was I was unimpressed with what I got. I don't know we're this race pump stuff had come about. I've never said anything about a race pump. I did try to run a oem 155 pump last year and want happy with it then every body said buy a mag pump I did still the low end hit isn't there. I know for a fact that the ski can flip. The problem is I have to be going 20mph + when I hit my set up wake to be on my pipe.

 

[MADMAT]

I don't know anything about this motor/pump set up but man that sounds like a lot of pump.

And I do know 2.5mm on a nozzle makes a difference. Good luck man! I know what you are after and you have been at it a while! That FX-1 hit HARD!

 

[jetpilot36]

MSD TL for the win. i gaurantee you will feel the bottom end. BUT at this pouint sounds like you're just masking another problem. do you have another pump to around the house to try? maybe a buddy's? you got any friends? j/k but if you really think its pump problems, i would try a pump swap and see if the brap goes up or down. 148 or even a 144 just for tuning purposes

 

[speedysprocket]

I agree with XJ, I run a 14/21 with 148 pump and Dasa 1200 in the same hull as you, but carbon and it seems pretty bang on.

Well Phil Clemmons says my prop spins, Erik who built the engine says it spins, and Frosty, who has the same ski, but a 1000cc, said I need to go to a 155 pump!
I hope you get your issue sorted though.

 

[102nd7]

Yeah I have access to a solas 144. But can't use it. 155 mm pump shoe

 

[chadman154]

I have ridden the PHP 898 in 5 different boats and never experienced what you are describing. It would seem you are propped way too low? 4 of the 898s were on TL and one on an HX3. The TL motors did hit harder on bottom but the Hx3 was still impressive. All of these boats were either on Av gas or vp110+
If I were in your shoes I would be getting TL, dropping in race domes and bumping up prop. just my 2 cents.....

If it were me, given how much you've spent on this ski and how important it is to get it right, I would road trip to PHP and ask them to set it up for you. They seem like great guys who'd help anyone, especially a customer.

That would probably be the best way to go about it. Unfortunately at this point in time I feel uncomfortable asking for help from them and would decline help if offered. I didn't come on here to hurt php's reputation I tried to leave them out of my original post. Although I know it would be impossible to do. I asked for help the only way I know how at this point. I feel I've exhausted all other option over the past 2 years. A BIG SORRY TO PHP FOR INVOLVING THEM IN THIS. The motor makes power I never said it didn't. The power is just unusable. A gentleman offered to help and gave me some ignition curves that I'm going to try out Wednesday.

I'm sure u've talked to zack, but like with any builder id follow every word he says to a "T" to make sure there's no room for error in the setup.
