Which pump?? Maxx 155 vs 160

[Robbie8984]

Hi Guys,
Have a 2015 new shape XFS comp with dasa 1200 and RRP pipe.

Had a max 155 75mm 14 vane with a 9/15 skat thin blade pitched to a 13/19.
Worked really well, not huge bottom but pulls really hard in the mid range on combos.

Got a Maxx 160 18 vane 83mm hub with a 12/19 thin balde, long blade skat. Pump was so tight, crazy almost un rideable bottom but lacked the combo power.

Pitched it down to a 11/17 and it’s pretty bloody good, not convinced it’s that much better if any than the 155.

What’s everyone’s else’s experience with this? In two minds to change back to the 155 or if I should keep working on the 160. Should it perform better than the 155 once dialled in.

Cheers

those leading edges don't look the same

The 160 has a long blade skat, and the 155 just a normal.

Long blade is ment to perform better from what I’ve been told.

Plenty of guys out there running 1200's with 160 and larger pumps doing multiple combos. I'm not one of them so can't advice there other than saying it's likly not a pump size to moter issue like you are hinting towards.

My vote is to keep tweaking with the 160 in. It should work just need to tune to the power band you personally like.

Hi Rob, To get it right. With the 160mm 12/19 longblade being so tight in bottom its almost unrideable. Was it agressive/violent or to doll/boring?

im wondering what you feel is good bottom I run a ET1107, with a 155 Skat trak 14 veins 75mm hub and a Longblade, thin blade 13/18 impeller and PFP dry pipe. It has nice bottom and strong through out the powerband.
Im pretty sure you should dial that 160mm pump in. otherwise put in the 155 and sell the 160 setup cheap to me lol
What i found out, is high level riders tend to have a very speciel pump setup and riding style that suits that pump setup.

Cheers for the replay guys.

With the 12/19 in the 160 the pump was mega tight, really violent bottom end. Flipped real easy and went big but when landing and gassing it again it was struggling to spin up and really hard to ride.

Felt way better at 11/17. I’ll back to back test both pumps when I’m back from holiday and see what happens.

Was wondering if bigger is not always better...
