You can melt down just one cylinder at a time, it happens all the time, some run leaner then others.... My buddy has 800+ hp procharged engines in his Formula, over last 7 years melted twice.... each time it was ONE piston.... its carbed also, no no per cylinder injectors.... it just happens that way...

Worried about the stock fuel line being able to supply the correct amount of volume to two bosch044 pumps. Surge tank will elimnate this issue.

Yes, I know what a surge tank is. I can see you're a car guy. A surge tank can help, but its not designed for continuous Full throttle, like a boat does. It can work in a drag race application because theres normally enough fuel stored in the surge tank to complete a pass. Theres no way around it, if you're fuel line is too small, at some point the engine can starve for fuel in a boat..

Theres a hundred thousand guys on here, who've done what you're doing, with probably 2, or 3 times the power your making. Replace the stock fuel line and pickup with larger lines, run a Aeromotive pump, or other marine style electric pump, call it a day. Unless of course this melted piston thing is up your alley, forget the car stuff for boats.

Agree!!!

Thunder is completely right, that surge tank deal is sure cool looking but will do nothing after about 12-15 seconds of WOT, could even make your fuel pumps suck air as tank level gets too low, it will only support as much hp as the pump supplying the tank can put out after sustained wot, I'm not sure how you drive your boat but I have ran my flatout (with over 1000 hp) for 5plus minutes before, when it only had 700-750 hp ran it at wot for 20plus minutes, think more like endurance or Nascar than drag race when you pick your parts, Smitty

We use surge tanks in alot of road race applications. Not sure of you guys are aware that the RETURN line from the fuel system is also plummed back into a surge tank to function properly. So any excess fuel the regulator bleeds off will also fill back the surge tank, once the surge tank if full it bleeds back into the fuel cell...

Either way, i am certain you guys are correct that i can work around the stock feed line just fine. Its just the factory line on my boat and fittings were very small.

Thanks for the advise, I guess i will just go with a single weldon fuel pump and call it a day. I am trying to plan the fuel system to be able to support large demand, as I will be tuning it on E85 at some point with much larger injectors.

Full force - Yes I know that some cylinders run hotter than others. That is why I have my EGT probes in the header for #6. BUT I have run a little too lean and done damage to one or two pistons - BUT - To completely destroy one piston I would think there would be SOME damage to another. If there was a bad injector or blocked fuel line I could see it. But that was ruled out and the electronics I believe was ruled out.
If it was timing then again I would expect damage on another cylinder. I would have thought there would have been at least one eyebrow deformed. Is it possible that that cylinder had more compression than the others? Less Quench? Loose spark plug?

I don't want to dwell on the surge tank since you are going to a weldon single anyways but do you understand what I am saying, no matter how much extra the bosch pumps dump back to the tank , after a certain period of sustained wot the max flow from the 255 dumping into the tank would be the max fuel you could get to the motor as it would be the only supply to the surge tank unless I am missing something? Its a cool looking set-up and I could see it working good on something where you were in and out of the throttle. In my case whenI went from 600 to 700 hp a aeromotive a1000 could not keep up under boost and I went to a Essex. When I went from 700hp to 950 hp a while back, I couldn't get enough fuel from that and I went to a aeromotive eliminator. When I went from 950 hp to the 1050-1100 I currently am running the eliminator wouldn't keep up so I added a voltage booster that sends voltage up to about 16 volts after 4-5 psi of boost. A big weldon would be a better set-up for me BUT I didn't want to overload the return regulator and lines and have to replumb everything again to handle the extra return when not into the throttle, I see since then they have a tick toc voltage reducer for that now. What are your hp goals in the future, these blower motors are fun and some is good, more is BETTER, Smitty

I totally get that, just saying I have seen just ONE do that a few times before, many small things could cause it to be more lean then others... crazy things happen real fast under boost...

I would be interested in seeing the spark plug from that Cyl. It should be able to tell us something,
