Re: Melting Intercoolers

Something to consider look at what another leading supercharger company has done to there supercharger.
I beleave looking at this. This port is to releave the boost at
low Blower speed high engine vacuum.

Pretty cool

This should help with the heat.

Re: Melting Intercoolers

I've seen this problem occur during start up, mild backfires igniting raw fuel soaked intercoolers usually due to fouled spark plugs, leaking intake valves or just out of tune. Charge temperatures usually never reach hot enough to melt aluminum.

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.:cool:

What kind of fuel system in the boat?I dont think duel needles are necessary but the bigger needle and seats help

Re: Melting Intercoolers

Check these out only thing I could find yet.

I have not called CSU on these yet.
Would need 1250 dominator equivelents though.

Fuel Aeromotive 2000s with 10 feeds 8 returns.
-8 feeding each bowl

Considering the belt driven Aeros. The 2000,s do move some fuel though.

After pulling out of my marinia I started to get on plane and I noticed the motor coughing a little and then it died. When I restarted it, which didn't go as easy as usual, I noticed ALOT of steam coming out of one tail. This concerned me so I Idled back to the dock, pulled the Core and knew something wasn't right. I rigged a way to pressurize the core but it wouldn't because of all the holes from being melted.
This was a standard alluminum Lee core. Most everyone agreed that SOMEHOW I had ignited fuel pooled on the intercooler which melted it. Hope this helps.:(
