"A" impeller question

[quiet riot]

Squirtcha, looks like we run pretty similar, I get 80 mph with n2o at 5600 rpm also, and I'm always looking for more. Thats why I'm building a new motor.
My sbf needs a little more n2o to get there though, as it has less hp to start with .

jd,
Do ya have any more pics of your boat? I like the bow shot but I'm curious as to what the rest of it looks like. That's a cool little rig ya got there and 80 mph with a sbf is pretty darned impressive.

pics, just not the greatest. They were taken off a dig camcorder.

Never really done any pic's while boating. I might have some from the drags if I can find em.

Also not clear on Spectra's rpm. The first one says 5600 rpm and the second one says 5300 rpm.
Squitcha, turning 5300 with the trapps, 5600 without. Just made the note ,cause I feel comfortable with the AL imp at 5300 wink .Too much money for S/S . I would go for the man bronze myself.

I have run an American Turbine AA ALUMINUM impeller at 5800 rpm for over a year,and have run the original Dominator A aluminum impeller prior to that at 6100 RPM. I'm starting to worry though and will buy a Stainless AA over the winter. BUT the boat is allways hooked up and I have no cavitation at all. I hear that the cavitation is the problem with the aluminums coming apart. TIMINATOR

O.K. Spectra..........all is clear now. If you're running 72 mph @ 5600 without the baffles, then what is your speed at 5300 rpm with em? I'm just curious due to the fact we may be seeing some noise statutes being taken more seriously here in Arizona. So far they're not really messing with anyone, but for how long? That's the question. A 300 rpm loss is an absolute killer. I worked real hard (and spent a lot of money) for those 300 rpm. It could all go down the tubes all over a set of $150 baffles and people with sensitive hearing.
Thanks
Quiet Riot,
Thanks for putting up the pics. Wow, you sit quite a bit further forward than ours eh? Or is it just an illusion? Looks to have a short deck but considerably more room in the passenger area.
