Pressurizing the **COOLANT SYSTEM?** Have any of you boosted guys had any problems with pressurizing the coolant system?
How much boost were you running, with what compression ratio and what head gaskets?
What did you determine was the problem and how did you fix it?

I seen two cars do this. One was one the spray and the other was boosted. They both ended up blowing coolant out of the overflow. Both cars had stretch bolts and we replaced both of them with GM MLS gaskets and ARP head studs 6 point.

Right now my combo is ARP studs with .058 Cometics and 9:1 compression. It was tuned at 14 psi. and made pretty good numbers, but I don't have any type of an intercooler or meth.
The first pass down the track it nosed off about 3/4 track and there is sprayed coolant all over the engine compartment.

You can actually have the layers separate and not properly reseal at cool down. A retorque of the head studs will buy time when this happens but they're going to go eventually.
