No problem with any input. I, too, am ignorant about this rigging and any experience or knowledge if helpful, even if it doesn't necessarily apply to my set-up.

Should the lines be bled/purged with antifreeze upon winterizing and re-bled again on spring commissioning?

I have mine going to the intake manifold. It reads around 20 at 4000 RPM with the stock plastic bravo pump...I would like to get the bronze pump, anyone ever try one? any good?

It shouldn't have to be. Its just like the speedo hose.

The bronze pumps from Jabsco have been around for ever and are nice pieces. I don't know what it would do as far as water pressure goes.

I do know that I had a new Sierra pump/impeller on mine, and I switched it to a new Merc one, and gainned 4 lbs of pressure at WOT. There IS a difference there.

I'm sorry, I totally forgot about that hose. As I'm not running a Stat, but a restrictor, I don't have that hose anymore. I don't see why it wouldn't work there, as that is a water passage direct from the block.

I don't like putting the senders in the block because it seems that they can get full of crap there from teh rust etc in the block. Thats why I like them up on the water passage in the intake.

I agree. Not to mention that getting to the block drain is a PITA
Thanks

Yelp mine keeps getting rust and sand clogging it up. I have a cross over I could run the water press hose up there.Good idear

I wonder if there is any diff in water pressure over the bockk drain plug over reading it in the crossover?????

Chris,
If you are interested, I will show you my rigging at PIB this weekend. We bleed off potential steam pockets and monitor the WP from the same set-up at the intake manifold.

On my Whipple intake they bleed off the back with a 1/8 pipe fitting with about a 3/16 hose t ing into 1 dump overboard.

My Littlefield blower Intake I plumbed the rear 2 port #12 the front 2 fittings T ing into it and them dumped thru the headers.

I have had 2 dyno shop guys tell me they have seen some HP diff getting the hot water off the rear.
