vf8 boost

[danz-rs]

whats a good but comfortable psi for the vf8 to be running?? like what would be the limit

[Bazza-NZ]

push it till it pop, then take it back one or two pounds and you've found it

around 12-14PSI

My VF10 ran 14psi for a while, seemed to go just fine. They dont hold that pressure past 5,000rpm anyways.

16psi is about the limit for a VF8 I've seen them run at up to 18psi but you would be just pushing hot air.

Damn my one stops at 0.7bar of boost (VF8) it'll go down after 5000rpm to about 0.5. But 2nd gear pull - I LOVE IT!!! Would dying plugs play a part in that too? wanting to do a change but i'm after platinum/iridium plugs. My wastegate actuator and the rod bit are a bit rusted too, would that do anything?

Whats your setup?

Have you chipped it or increased boost? a VF8 running on a stock ecu will be around 10psi.

Umm it's all standard. It may have an air leak somewhere in intake as I get a pop in the exhaust or is that spark plugs?
