Custom/Hybrid 1000cc Pitch?

[munki63]

Looks like im getting a 1000cc Dasa thrown in a bob3 with a 148 mag, what are guys running and are you happy with it?

Cheers

edit
PFP and TL

I have a Rickter XFR with a 850 DASA, 144 set back Skat mag. I am very happy with the set up. Backflip no problem off boat wakes and Surf. And no trim needed in surf. I have Flatwater backflipped but much more technical to flatwater flip.

So what pitch impeller are you running in your 148 mag pump with a 1000cc DASA?

 

[Jr Freestyle]

What pipe?

If pfp I say 11/17

 

[munki63]

What pipe?

Are you talking 11/17 Hooker?

PFP, XM recommended Skat 14/19 (Enhancer/B-pipe) 16/21 (TL/PFP)

A Hooker won't do too well in a 148 mag pump :biggrin:

I think you're limited to Skat 148mm impellers.
I believe I am running a 11/16. Not a DASA motor nor does it have almighty PV's - just my mellow ADA1000.

 

[munki63]

Ya, that 11/17 number is just thrown out there a lot, just wanted to make sure.....

your 11/16 would be slightly less aggressive as an 11/17 correct? Ive been in this sport how long and still am terrible with pinches of impellers lol For thoes of you who followed my last build thread know ill probably run thru 3 different ones before i decide lol

 

[Matt_E]

First number = leading edge
Last number = trailing edge
Numbers are in angles, so the bigger the number, the more aggressive it is.

Kinda what I thought... so for freestyle you want a pitch just so it wont cavitate or is it more like rider preference

 

[Matt_E]

Depends on motor and pipe.
The DASA PV motors seem to like low pitch on the leading edge and lots of compression with a PFP pipe to get through the bottom power into the crazy midrange.

 

[munki63]

So back on topic lol, what are guys running?

thats not really a DASA charactreristic...moreso of the pipe


key with a PFP is COMPRESSION

if not running big CC with high compression the benefit of a PFP will not shine

 

[munki63]

I'll be running pump gas compression, PFP, MSD TL..... nice swapping posts Idok lol

I run 185psi and have no complaints about the PFP :biggrin:

it was the booze!

I run 185psi and have no complaints about the PFP :biggrin:

thats because 185 is enough.....but 160-170 is NOT....many folks who THINK they are running 185 really are not



PFP likes compression..plain and simple...thats a pipe, not an engine characteristic

 

[Matt_E]

Oh, gotcha.

There was no difference in low bottom end between B-Pipe and PFP. But once it got past that really low point right off idle, the difference is ridiculous.

 

[munki63]

Impros "Skat 13/17 in there. You can vary a little each way"

 

[munki63]

Also what bore are guys running at the nozzle... Anybody?

 

[Matt_E]

87mm for me.

Props and pump set ups are confusing to me as well. Way to many to many combos . I really think its a feel thing . Builders / boards can get you close but you still need to do a little bending and nozzle swaps etc. to get it where you want it.

I think I would prefer a prop a little short rather than tall.
