could some one explain the term boost reference?
thank you
later
Dave Hughes

Dave a super charger is always creating vacum under the carb thats mounted on it there fore the carb does not get true signals at part throttle ( sometimes the motor will be in boost at part throttle but the powervalve is closed as it still see's a vacum so it cooks the pistons ect.in a lean cond.)),to index or boost referance is to run a vacum line down to the intake under the charger and drill a passage into the power valve circuit in the carb ,,the carb gets true signals and the jetting and power valve can be adjusted right on no matter what the blower is doing under the carb or throttle setting ,,this is the extreme basic explaination ,if you need more just p.m. me :D :D :D

HOPE THIS HELPS YOU :D

Easy there boss. ;) I didn't mean this to come off as a slam in any way. Saying in only 6 replies was my bad.

I know Tim well enough to know that he researches all this stuff before hand and that he still felt very comfortable about choicing Dean. I could be wrong. (Been told I have been before, but I still don't believe her. ;) )

I agree, that all of the info on this board comes from either direct answers to questions asked, or from replies such as from cessnas that bring up more questions.

Bobby,
Isn't the boost reference going to
be from the intake, under the supercharger ??

Your for sure righjt ,,my typo it has to come under the charger to get a true reading///sorry for that typo and great catch ,I can't type or spell for sure !!!!!!!!!!

USA_! sorry I thought it was a slam fess getting ready to open ,
sorry I read it wrong:D :D :D

My guess is 82 MPH before ...
 

... the poor old Bravo grenades!! :D

Remind me not to ride in that boat with you, because it will either...

A. Get me killed

or

B. End up costing me a ton of money to keep up and land in divorce court.

Good luck and have fun!

Hmm, you been through how many drives in how many hours now? Just kidding LOL! It all goes back to the 12 inch theory. (For those who don't understand this concept BudMan was contemplating upgrading a 350 to BBC and keeping the Alpha. His plan was to take it easy, the Alpha won't know the difference if you are gentle. I ask him if he had a 12 inch ___ how much would he not use?)

I think if I am easy on the stick and don't accelerate hard that it will live some additional time. When it goes it goes. I am due anyway.

As you know I have about a thousand hours seat time in this boat in many conditions. It felt very stable when testing and I was breaking 75. Just pay attention to all things, it ain't a toy when you are going that fast. Saturday looks iffy on the weather. Sunday looks good. Let's get yours running Saturday. 70 plus on Sunday and the river is looking great!

Tim, looks like you're still using the 12-inch D**K theory to me... :D

Sounds like you got the water pressure problem straightened out...

Tim,

Thanks for the information on the prop. The original engine was a 7.4L , 330 crankshaft hp. I tested the 502 MPI today with some problems. I will start a new thread on that one.....

Mats

Tom,

Try to use it everyday! I know it will scatter, everything does sooner or later. I just want to get a summer out of it so I am not over budget this year. Water pressure situation is close, just need a little co-operation in the weather. What about Sunday?
