i recently added a set of bassett headers to my boat and i did not want to run the water through them as i was concerned about water seeping back into the motor also i am running baffles anyway, my question is this if i run the water will i see any noticeable difference in temperature? i nearly fried every spark plug wire off this weekend and they were in looms on top of the valve covers. i am going to wrap the headers and run the plug wires underneath the primarys this time but thought i should seek opinions about the water injection before i waste another set of wires thanks :angry

do it "KONASTYLE"!!!

IF you look closely those headers have some weep holes at the bottom to prevent the water from going back in as well as the t-valve is supposed to kick the water in once the rpm's are up there...

On my Southwind at night the headers would glow red untill the water injectors.. I would definatly run water... But if you dont the wrap should work! Also running water prevents the headers from turning blue (or rainbow) but if you ran them all weekend they are probably already that color...

Good luck!!!! :good

The best way to preserve you headers is to have them Jet-Hot coated and run them dry. Water going back into the exhaust is from reversion and it has a lot to do with the cam. If the t-valve is working correctly, it should shut off the water when you back off the throttle, but there's always that little bit left that can be sucked back!. The weep holes "DO NOT" prevent reversion, they are drain holes to let any excess water to drain out after you shut the motor off. If you run your plug wires right, they will not come in contact with the headers whether routed on top or bottom, although on the bottom is a better choice!.. A note about wrapping headers, a friend of mine once lost a brand new custom set of headers in his race car in less than two years from wrapping them. Every time you run it they get hot and when you shut it off and cool down, it sweats in between the header and the wrap and it gets soaked and takes forever to dry out, in the mean time it rusts the headers away! If you wrap them you need to take it off everytime you're done, I wouldn't waste my time on it myself. I been running mine dry for 10 years now with no problems, it is time to get them coated though, tired of looking at blue headers!.. :laugh

Hope this helps!.... :good
