Freestyle Solas concorde or hooker for a stock stroke dasa??

[sniper]

Hello
I have a dasa stock stroke dasa 771 pv engine with an oem pump with a 10/16 hooker in it.
Would a solas concorde 13/15 4mm cutback work better with my engine setup?
I'm trying to get a little more bottom end hit out of it.

Thanks/Tomas

It might let that engine spool up a but quicker. The 10/16 would be a tad tall for my liking on that engine. U want the revs up and pushing enough exhaust pressure to pop those PV's.

Ok I will change to the solas thank you
I also have a ATP stubby cone lying around, is it something worth putting in to help with the bottom end?

i would repitch the hooker 10/16 to 9/15 or 9/16 for better results.

Yes, the shorter cone will help with loosening pump and increasing power on the bottom. Also try boring your reduction nozzle larger if you havent already.

Do you think it will be better then a 10/16 hooker or the solas?

Use your 10/16 hooker with a bored nozzle first. If it is still slow to hit, raise the trailing edges .1 inch.

The nozzle is already bored if I raise the trailing edges would that make it a 9/16 or how does it works? I don't know much about impellers.
I think I'm better of getting a new one, question is should I buy a 9/16 or a 9/15?... or maybe just go with the solas.....?

As far as I can tell, a Hooker 9/15 is a repitched 10/16.

Hey guys im new to the stand ups and just bought a super clean 89 650sx and wanted to put a new impeller in. im looking at the Solas 13/18 with a R&D scoop grate. is this a good impeller for low end? Thanks!

Every impeller Solas made for the Kawasaki 650 is on the high side, the older round nose hub is about right out of the box. The newer pointy hub needs to be repitched. An 8-16, 9-17 Skattrak will work without modification as will a straight 15.
