[JetManiac]

Trying to help someone out with impeller selection.

B1 with Kawi 1100 with Solas 144 pump.

Solas concord
or
Skat c-75

Pitch recommendations?

I run stock pump w/ 15/22 concord and very happy. I know others use 16/23 as well

If you want smooth power, run 16/21-22 range. If you want it to really pull, drop down to a 14/18. Kawis make power higher in the rpm range than yamahas, so if you pitch them to rev, they run much better. Not knowing if your buddy has dried out the pipe or not, but if he did, lugging the motor with a larger prop actually adds a lot of detonation.

Was gonna say "Hey Chris, Why have you not hit up scottie mac yet?"

I've ridden a ton of b1100s. All I can tell you is, the difference between one that runs OK and one that is 'd@mn, that fcuker is awesome' is usually poor prop choice. My old race 8mil pv blasters were quick as $hit, and set up right, a near stock kawi 1100 with head, reeds carbs and timing advance is just about neck and neck in terms of holeshot and top end. Best thing is, the 1100 does it on pump gas all day long and isn't even breaking a sweat. A lot of riders worry about high revving triples, but it's detonation that is the triple's worse nightmare. IMO, if you aren't running 7650 PLUS rpm, you aren't even in the zone.

Not meaning to step on toes, just telling it like it is from all of our testing and racing over the years.

16/21 on mine....leaves me good bottom end as well

Same impellers a good choice for a yamaha 1100 b1?

 

[scottie mac]

Yamahas are a different animal. They run lower rpms because of the pipe design and the low rev limiter. Ask around on pwctoday or the FB Waveblaster page. Lots of guys over there have dropped in 1100/1200 Yamahas, they would be a better source.

16/23 in my slightly modified blaster it would fry it off the line. It had so much torque it scared me so im putting the engine into a superjet
