PM rocket man I think he,s melted a couple.

Liquified like a torch.
Interseting on the Rocketman senerio.
I wonder if he was using the PSI,s at the time.
I have a pretty good idea of how it occurs just wondering about other thoughts.
Thanks for the replies

Are you running it dry at idle? I have plumbed mine off the sea pump rather than the force feed some riggers will do. Pretty hard to melt when filled with cool water.

I was at Whipple last year inquiring about their intercoolers. They showed me about a dozen melted cores. I don't remember what they said about why it happened. They sure looked like they got hot. They use that cupronickel (spelling?) core. Real expensive. Sorry, that's all I know. You might call them and ask for Dustin. He'll tell you.

Yes I run the copper cores from whipple. I have not had problem with mooneys
but stepping up to PSI,s and I have neen warned.
Currently running a force fed system but considering dedicating a water pump stage just for the chillers.
Just trying to prevent a barbecue.

I bought Rocketmans old deal last year. He had told me he melted down a cooler, but I don't remember exactly what set-up he was running at the time. We are currently running a Whipple cooler under a 980 Whipple blower w/force fed water. So far all is well. We have approx 20 hrs on the motor and no problems yet. The blower does run extremely hot though (can't hold your hand on it while underway) We don't know if that's normal or not for that blower and need to look further into it. What were you warned about w/the PSIs?

We force feed every innercooler we have ever used and never melted one????

I was Warned of core melting. At Idle the PSI is going to want to make boost
Just like your R980. These things are overdriven like ya read about!
After discussing this with PSI. The cause is fuel starvation causing a
Lean condition firing a controlled fire above the intercooler.
Carburators are the biggest offenders Must run atleast .150 needle and seats
maybe even dual needle and seats.
The blower actually can suck the bowls dry.
Some of the big dog engine guys bandaid this by building a plate which
deflects the pie shape discharge from coming in direct contact with the
fins on the chiller. The fire if created will not burn the chiller.
This is not correcting the true problem.
If you look at the new 5.0 whipples they have incorporated a discharge
bleed off on the rear of the charger. This will bleed off the excessive
pressure at low engine speed high vacuum. Pretty Slick!
