>14psi on ceramic turbs?

[JH32]

I was thinking .... you measure your boost pressure at the inlet manifold, and it's say 12 psi with the stock cooler and stock turbo.

If the stock cooler has a pressure drop across it of around 6psi, this would be equivalent to your turbo pushing out around 18psi?

Then ... you upgrade your stock cooler to a nice FMIC with a pressure drop of say 2psi.

Could you then set your boost to run at 16psi (measured at the inlet manifold)??

The turbo would be running just as hard as before, but with a smaller pressure drop.

anything is possible but for how long

run it at 16psi and it wont last long... but then its an excuse to rebuild or buy a bigger better one. so everyone wins!

I was thinking that 2,When i put my fmic.I think our theroy is right its making the same boost,same heat ,Just less restriction in the fmic.

I just dont remember how much of a boost gain i got from my fmic

???

I see the logic...But..

When I installed my fromt mount IC there was no difference to the boost settings...

I also measure my boost from the manifold and I installed an APEXI Hybrid I/C... (definately felt the better flow of the cooler) but no boost decrease or increase...

Are you sure it's a 6 psi drop accross the standard I/C?

Hi Guys, the 6 psi restriction is at 6,000 rpm and 12 psi. At 4,000 rpm (a much more common number) the restriction was less than 2 psi.

I don't know about you, but I don't feel it.

As for how long the turbo will last, remember that boost is not the only problem for the ceramic turbine. It does not like heat either, so when you turn the boost up it runs hotter (more air in means more exhaust out). Too hot and bye, bye turbine.

Hoep that helps clarify.
