HELP?! Trouble building boost with twins, on transbrake
Little rundown on the car.
03’ terminator with twin Precision 64’s being controlled by the AMS-1000 boost controller. Laid down 1060rwhp on dyin @ 23psi. Trans is a turbo 400, reverse manual valve, with transbrake on 1st & 2nd. “3500-3600” stall ( PTC said this is the one to use and figured they were correct since they’re the manufacturer.
The problem we’re having is no matter what the 2 step is set at and no matter what the boost controller is turned up to the car won’t build more than 10-11 total boost psi while WOT and on the trans brake. Regardless of how long it sits there, or how high the car is revved it just won’t spool any higher.
Once the car CRAWLS off the line, literally not even cracking the tire loose and gets past the 60’ it sounds like a jet engine spooling and takes off like a bat outta hell LOL
Just frustrating when the 60’ times are 1.9-2.1 and 1/4 ET is mid/low 11’s with a mph at 150. Any advice OTHER than saying the stall is too tight??? Thank you guys!
