Precision turbo 5557

[AllBoost]

ok guys i am trying to get some specs on the 5557 turbo from precision. im looking at it t go on my srt 4. yes i said srt 4 but i cant find any information on these turbos on our website and i know you guys rock these things and alot of you love them. wondering about some of the characteristics of this turbo because i currently have a 55mm turbo on my car and full bolts on and prolly make in the 400-425 range. but im looking for something new and in the billet wheel family. im really trying to figure out about when this thing should spool and when full torque and peak horsepower will occur. for a reference the only guy that runs a precision turbo on our forums has the 6057 i believe and he see 25psi, untuned, and with a leaking throttle body and afrs that didnt come out of the 10.0s make 430 horsepower and 400 torque on a mustang dyno, full boost at 3800. so alot closer to about 475/450 on a dynojet. maybe a little less.

lol i have no idea, why not contact precision directly instead of bumping a thread on a evo forum about a turbo used for a srt4? Not trying to be harsh, but since its middle of the week I think Precision or a authorized dealer for them should be open. Also when it should spool and how much torque and HP it makes will depend on your setup and tune. All cars and setups are different so the definate answer would be strap it on your car and see what it does......

lol exactlly my first thought was, called and i told them my setup, they had no knowledge the srt crowd even used this turbo. told the about the guy on our forums with it and he was surprised that the 6057 spooled so early. lol so thats why i came on here. i know you guys arent stupid about your cars like some srt guys are. i believe the reason your guys love these turbos is because they hold boost nicely with your guys 8500 rpm in some cases and make great power up top.
my setup as it currently stands:
diablo tuner
dw 750cc injectors at 43.5 static pressure, i have my base pressure at 58.
walbro 255
injen intake
agp delta 55 turbo kit (log mani, 3in O2 housing, and there 55mm turbo and 38mm wastegate with open dump)
3 in custom turboback exhaust (undercar dump)
hks bov
turbo xs boost controller (21psi)
and other little things i cant remember right now
