I am not normally a poster here, but can't resist the temptation to second
Kevin's thoughts on your "sharing both your accomplishments and follies with us
all." I also was glad to see you not abandon the turbo. Like others
may have suggested, I think you are being way too conservative on your "Max
Boost" figures. Unlike intake valves, etc. ... what's to break?
Thanks for
the comments. I'm not shy about posting the bad along with the good.
As Ed says, if you're going to make mistakes, make new ones
:-)
As
for "what's to break", the answer is apex seals. Boost itself won't
break them, but detonation will. You can run just about any
boost you want, as long as you can keep the mixture, timing, air temp,
and engine cooling under control. I'm just trying to work my
way up in boost cautiously.
I hope you do not become so
sucessful at holding the boost down by porting or whatever control scheme you
end up using, that you lose the ability to go to a "War Emergency" power setting
of "all it will put out" to help you clear a ridge, or
whatever.
Not to worry
Dale. My goal is to be able to use the wastegate to adjust boost from
a minimum of 3-5 psi, to a max of about 12 psi, when the throttle is wide
open. At the moment, the wastegate is too small. When the
wastegate is wide open (minimum boost), and the throttle is wide open, I
have 10+ psi of boost. In other words, my boost control range is
currently from about 10 psi up to some frightening turbo
destroying level. Porting (enlarging) the wastegate will
allow me to lower my controllable range, hopefully, to at least as low as 5
psi. Once I get the controllable range down, then I can pick and choose
the boost I want without having to fiddle with the throttle
position.
Cheers,
Rusty
