Dry Headers

[Taylorman]

Can anyone share any experiences they may have running headers dry vs. wet. Im interested to see if there is a noticeable increase in rpms's What was rpm's you run at and what increase did you see.

I saw maybe 100-200 rpm increase if any. Its sounds cooler now and I'm no longer worried about how much water is going through at what RPM-Aluminum Squirt

makes for a much warmer outing! (depending on how big your boat is)

Basically we are thinking about having a shut off valve to pick up some more rpm just at WOT for short amounts of time.

I run my dry, it gets the boat, along with the back seat pretty hot.
I think I will add some type of cooling this year.
Nighttime running is pretty scary when you look back and see the headers dull red up to the first bend.

The police DO NOT like it AT ALL.

Nothing like the sound of an unmuffled big block at WOT.

What type of engine and @ what is your max rpm where you saw the gain?

They rust quick Taylorman. At least my friends did.
See ***boat decals in the Sandbar.

I don't plan on running the dry all the time. Like Matt said, were just wondering if we will see an rpm increase at wot for short periods. I plan on ceramic coating the this summer also, so that should help with rust.
