Boost will not hold on the drag strip. Not sure why, but now suspecting wastegate is fluttering. Basically pulled the wastegate line and still can't hit over 22 psi and then it tapers down to 17ish...
On the freeway in 5th, I can hit 25 psi and it holds steady..... That by the way is probably 500whp.....Ungodly fast....
That said, I still managed 12.446 and 12.456 Saturday night.
Just ANOTHER 1990 Legacy turbo conversion.... hahahahahah

Re: Just ANOTHER 1990 Legacy turbo conversion.... hahahahah
Josh, did you ever see the daily wagon? Can't remember?
Added a helper spring.....
It frigging helps!
20 plus psi in 2nd!
25psi in 3rd!
OVER 25 in 4th.....
We are talking 500 whp territory now....
Uh..... Tranny may be making whining sounds....
Time to retune and hope the whining sound is either low tires or wheel bearing(s) or rear diff.....
It was a $3 spring from the hardware store. Boost seemingly holds hard and solid now, as well as building faster.
What WAS 22 psi on the MBC is now OVER 25 psi.... and holding, versus tapering...
Guess why this boost graph looks so funny?
The boost would hit, then the wastegate would leak....
OF COURSE.... No concrete proof till this weekend at the track....

Doug,
No I don't think I ever saw the daily wagon. It's been quite a while since I was out there.
