water restrictors on basset headers

[bakerjet]

i just installed the .125 restrictors on the the inlet water lines and seem to have more water on one side anybody have this happen? it's not blueing the headers i just have more steam on one side.

I drilled mine @ .060. Restrictors should not make one side steam more. BL

[bakerjet]

so you drilled them another .060''? think i need a valve on the outlet to pinch?

[Wicked Performance Boats]

I didn't drill them more. The header to hose adapter, #8to#8 male, is the right size to use an 1/8th np tap, then install 1/8 pipe plug. Then drill the pipe plug to .060. but if your flow is not the same, something is plugged. Budlight

I had the same thing happen,either drill out the side that has less flow or order the next smaller size and install in side with more flow.Buying the smaller size restrictor worked for me anyway.

i found a small piece of trash in the hose i bet that was it. thanks guys. :rollside:

Has anyone tried restricting the flow to water jacketed headers such as Lightnings? I've been told that you only NEED enough water to keep the rubber supply hoses from melting.

Anybody??????
OK, how 'bout this; do Lightning headers come with instructions? If so, what size supply lines do they recommend going to each side? My boat already had a -10 line going to each side, I was thinking about going to -8s.

you need enough to keep the rubber hose from the header / tail pipe from melting. Most dump all the water out the jacketed headers that I see.

[Duane HTP]

It can be done, but if you do it that way, you have defeated the purpose of the water jacketed headers to start with. So why bother?????

I ran my 5/8 hoses from the t-stat cover to the header manifold inlet, then 3/8 hoses (4 each) into the header tubes. Works fine.
Mine were used, so no instructions, new may, I dunno.
only odditty is a "drumming" exhaust note that varries rythmically :RAAAaaaAAAaaaAAAaaaAAAaaaAAAaaaAAAaaa. It's a little like a muffler effect coming and going, and it kind of swings left to right. I let the admiral drive while I looked over the transom and the water flow out varries in volume for some reason, and switches sides. When more water exits left, it seems to steal from the right, and quiets the left, loudens the right, then it reverses itself, then again a couple secconds later. Have only seen this at cruise. Haven't been able to have her open it wide while I watch. I still have to bump her temps back up some more. I'm running about 115 WFO, 155 idle and want her just a bit hotter (130-140 by arround 180).

So, I assume most people just dump the water from the engine out the headers. Does anyone get their header water supply from before the engine, so that cool lake temperature water is running through their headers? Could I use a Tee (supply, headers, engine), after my shut off valve at the pump, to supply cold water to the headers; or would most of the water want to go out the headers because of the minimal restriction?
