Any problems with Lightening Headers?
 

Do lightening headers have a problem ingesting water into the engine? Not a freak thing, but a regular occuring problem. Thanks.

Mine and Cory's did okay.

Guess it depends. They are no different from any other header. You can vary the point the water is dumped into the exhaust and how much. It also depends on your cam/displacement.

I had a set on a jet boat for several years. Had a pretty good cam. Never had a problem.

If you talk to Jahn or John (what ever his name is)at lightning he will tell you the normal wet lightning headers will revert water as easy as stock manifolds. My 502 and 540 were fine with them on with a 600 lift hyd roller w 228/236 at .050 at 700 rpm's idle with merlin iron heads,my new 540 with 600 lift hyd roller w/236/240 at .050 and afr cnc heads would STALL at idle from terrible water reversion with them.So there is a point depending on cam and cyl heads where they will not work unless you "dry"them up by adding water further back,Smitty

Had lightnings on a 89 Regal Velocity 454 mag and on my 98 Velocity with a 502mag. No problems and better performance.

Great product and cannot be beat for the price. Jan is easy to work with and will build to suit if required. We've put them on dozens of boats with different configurations and had NO problems to date. In fact, we have them on our own boat.

They are a good deal for the price and there quality with the new materials they changed to about 10 years ago is very good. It is a fact though that Jan at lightning makes clear is the normal,wet version will revert water as easy as a stock merc manifold so when you go past 240 dgrees duration at .050 on the exhaust side you are entering reversion territory,Smitty

Dean, I noticed the above information from a previous post of yours. I have attached a copy of the installation instructions that I received with my Lightnings. Notice the 5th paragraph concerning reversion and cam duration. I would have to say that you are a definite candidate for the dry tail pipe option with a duration of 260.

We installed them before with no problems. We also have them on Blown jets with no issues. They look & work great Just watch the cam size & dump the water late in the exhaust if you are going big on cam. Jamie / Lakeside :)

I wrecked an engine because of lightning headers. But it thier defense the inner tube had cracked, and would alow water into the cylinder once shut off. I did replace them with Lightnings, but the new ones carried the tubes over the top before joining them all. Like an E top designe. This was late 90's.

Dude, That was EXACTLY what I needed to see, THANKS!!! now for a second question, can you scan and e-mail the whole doc to [email protected]? These were delivered to the shop and I never saw the installation instructions. THANKS!!!

Dean, I just sent you some info....
