Hey guys,
I just got back from the track last night where I posted my new fastest time of 12.7 @ 114. This run was on 18.8 psi. I decided I wanted to up my boost to 20 psi and see if I couldn't get a 12.6 or 12.5 run in. After I raised it my car got slower, not by much, 12.8 and 12.9 runs all night. On the last run of the night I decided I wouldn't try to pay closer attention to the boost controller. When the car went into third gear boost progressed slowly to 19.8, I then heard a boost leak and pressure immediately dropped to 17.5 psi. I've checked all the intercooler lines and vacuum lines for leaks and couldn't find any. So I believe the stock BOV was leaking. I can hear my blow off because of the blitz intake. Have any of you had similar problems with the stock BOV and if so, what can you do? I don't have the money for an SAFC or VPC and an aftermarket BOV. I could buy an aftermaket BOV, but I don't want the car to stall after coming of a WOT run. Anyone know if HKS as fabricated a recirc kit for the Supra's yet. I know they have for the Eclipses's. Any help would be appreciated.
Thank in advance,
Jesse
