10421, Timing and Boost dropping probs...
Posted by Hult250R, Jun-24-04 02:08 PM
I checked my timing yesterday and it was way off. When i put the head back on las year I didnt check it after i Put the CAS back on. I adjusted to for 5*btdc. Made a few pulls and my knock is pretty much gone. Time to get it a lil better :thumbsup
If I get a knock count of say 15, my timing will stay at around 23 is that normal?
I staryed setting my AFC last nite a lil too. Im getting about -25 on the Lo settings and my Hi side is closer to -30 (650's and a 16G)

Now on to the boost prob...
Ive got my boost set at 20psi now. At around 6k rpm's it starts falling to about 16psi... What gives? I checked all my IC piping and connectors and I cant find any leaks. The stock 1G BOV (uncrushed should hold that shouldnt it? Any ideas?

well lets get more specific

First off, what kind of turbo/how many miles on it? Is it ported?

What kind of IC?

as for the knock, have you tried tuning at, say 18psi and see if it continues?

*edit* I don't think an un-crushed 1gbov can hold 20psi...
