(t3/t4) when should i expect a .63 a/r housing to hit in the rpms range? and how long will it pull (rpm range) with a 50 trim compressor.. for a b18b1 w/ injectors & safc hack.. planning on boosting 7-9 psi

any differance using a straight t3?

 

Id also like to know!

 

I would say on that motor, beginning spool around 2800-3400 and full boost by about 4500.

Stick with the t3.t4 design.

 

It helps to know the manifold design/maker, downpipe size, cat/nocat, exhaust, ebc/mbc or spring only?

When you say:

What do you mean hit? Hit 1psi? 7-9 psi? HP? Torque? A Cow?

 

T3/T4 Pritty fast
T3 FAST

 

yea there many variables that can increase/decrease spool time:
the exact size of the turbo
wastegate spring
manifold
intercooler size
piping design
boost controller settings.

i can say that my t3/t4e 60-1 stage 3 .63ar hits 7psi in 5th at 3700rpm and thats on a 9:1 b20vtec motor. 3rd gear takes a little longer(~4300rpm)

 

i'm running a 60 trim and i'm in full boost at about 4500.

 

I know its not same setup as yours but I got B18C with T3/T4 .60/.63 57 trim.

Spool starts around 3200 and full boost by 4500 rpms @ 10psi. 2.5" piping.
