This is the goal of my turbo setup, quick spool, and holds the power for as long as possible. I know its an .48 a/r, with a stage 3 turbine. Any ideas what trim it might be? It was suggested that it may me a 50 trim, but that seems small to me. This was at 10psi.

Not sure who's graph this is...hope they don't mind!

 

the properties of that picture say its a drag kit...i dont remember what turbos come in those so you will have to look

my guess is a t3/t4 50 trim. with .48 exhaust housing

 

I know it was a custom kit, but he might have swapped everything but the turbo...?

drag kit comes with a .54 trim i believe

 

where did you find the graph? evans-tuning forums?

 

60 trim .63 A/R hotside T3/T04E, cheap turbo kit, 2.5" DP, 2.5" exhaust, 9psi, bone stock 94 GSR



.60trim .63 A/R T3/T04E, 3" DP, 3" kteller exhaust, 11psi, peakboost kit, bone stock USDM GSR w/ headstuds + cometic headgasket

Point: manifold and downpipe make a huge difference in spool time.
nearly 1000 RPM difference between the two setups in terms of spool time, with the faster spooling setup using a 2.5" DP. When it was upgraded to a 3", spool times dropped even more. Responsiveness in both setups was excellent above the point where the turbo actually spooled.

 

The graph was with a ramhorn style manifold and a 3" downpipe and exhaust...

I don't understand how how more boost, bigger dp, bigger exhaust and it spooled later than the over setup...?

The smaller dp and exhaust had 150ft/lbs at 3900rpms while the larger dp, and exhaust had 150ft/lbs at 4700rpms


...still wondering what trim to go with, though the 60 trim .63 a/r doesn't look that bad

 

any other input?

 

Whats your motor setup??

It would be easier to reccomend a turbo for your needs if we know what you are working with..

By that dyno graph it shows he made a hair over 280whp and 200trq..

This is example..
I was reading about a week or so ago. Stock GSR motor from oilpan to valvecover. He had a SC61 with .63a/r hotside and at 10psi made 301whp on pump gas..

 

It's a .48 A/R 50-trim
