Anyone ever melt there core Please tell me.
I would also like to know why you think it occured.
Even if it happend to your friend. Please explain.
All opinions Please.
Engine builders are welcome also!
Please Respond.
Thanks in advance

Re: Melting Intercoolers
The most common reason for a core to have a "melt down" is do to lack of water volume. Using a good sea strainer for the intercooler seperatly will help prevent this from occuring.

Re: Melting Intercoolers
This is why I am taken your advice on the dedicated
water pump Stage.
What else do ya think causes this catastrophic event?
As Always Dean Thank You.

[at a 14-71].The smaller the blower the more heat.An 8-71 blower I wouldnt run beyond 8 lbs.I have seen cores melt from the underside due to reversion problems.Cupernickel cores can withstand the most heat.

Re: Melting Intercoolers
After conversing with engine builders
and also the leading Supercharger builders. I am hearing such different opinions on this.
Allow me to think out loud.
Blower disharge temperture would have to exceed 800
degrees to melt alum. Never mind copper.
So what is the cause?
Does it seem to happen more on Carb Deals?
If yes Then lets look at fuel. Where do we measure
the fuel pressure ? At the Fuel rail right.
So lets say that the Super charger has the ability to
draw the fuel from the bowl that the 4 little .130
needle and seats cant actualy keep up. The fuel pressure
still reads good on the dash. Got me?
So it has been mentioned to me that the cause of this melting
is a actual backfire igniting a fire above the intercooler.
and the lack of fuel is the cause of this.
Does this sound possible?
Or should I just go back on the couch like everyone else
is with my pounding headache.

Re: Melting Intercoolers
Excessive heat from the blower can melt a core and like Dean said poor water flow.Even with proper water flow you can melt a core if you spin a blower past its efficient range.A roots style blower, I wouldnt run past say 12 lbs. of boost

Yes but Jeff do you beleave a Blower can actualy produce
that kind of discharge temp?

Re: Melting Intercoolers
Fuel is what cools the blower.If a motor leans out it can shoot blower discharge temps greatly.Blower cavitation makes tremendous heat and is probably the culprit.Fuel volume is very important.You can have pressure and no volume which could lean an engine.Pre-ignition can flame back and melt a core.
So how can I make certain we have enough fuel.
How about dual needle and seat carbs or atleast .150
titanium seats.
This was one of the big boy supercharger gurus suggested.
( I think ya know who) Every one compares theres to his.
