Bandit 800 SC's???
I'm currently looking at a boat with Kurt's Marine, Bandit 800 SC's. I've tried contacting them a couple times the last few days to find out how the motors are set up, but they are getting ready for the race this weekend and couldn't get back to me.
Anyway, I first choice is to removeg the blowers and run them natrually aspirated, second lower the boost to 2-3 lbs so I can run 650 hp or so depending on how the motors are set up.
I am wondering if anyone can tell me what compression ratio Kurt run's in his 800SC package?
I am affraid that if the comp. ratio is below 8.5:1 I won't be able to make any power without the blower. The long block is 572 cu. in.
Anyone know the answer? I'm going to post in the tech section as well.
Thanks in Advance!

Kurt builds a good motor, he uses the Olds Drag racing heads.
He's better at answering emails than phone calls. Give this a try.

I believe he's leaving Thurs afternoon for Cambridge so you might need to wait until next week to catch him.
If you want. PM me with all your questions and I'll try to get the answers. Make sure you tell me the boat and customer's name so he knows which set of motors your discussing.

Well, I found out more this afternoon. The bottom ends were built by Kurts back in 95' but didn't have blowers. When the new owner got the boat he had the motors rebuilt by Performance Marine (now out of business) and had the blowers added.
They are running 4-5 LBS of boost and compression ratio is 8:1, to low for a NA motor. I would need to lower the boost to 2-3 lbs.
I wonder how many hours I would get with that kind of setup and how much power?

Re: Bandit 800 SC's???
Panther- Merc 800SC's had a 7.5:1 cr/700hp at the prop. How many hours on the bottom end since being rebuilt by Performance Marine? How many hours on the top end? I assume it's a 4.5x4.5 572? The 4-5 lbs of boost is modest and should add to the reliability. Not knowing what components are in the motor, I would think 200 hrs before refreshing the top with a toatal rebuild anywhere from 400 to 500 hrs based on usage, leakdown etc. Don't know what hull they would be in but the torque and responsiveness of blown 572's is impressive. Just trying to help.
