Oh...i guess the only time i've ever heard that word was from a "friend" of mine who is a huge WoW dork. I dont know anything about the game so i can't say for sure...

I am making 416hp @15psi on pump gas with this turbo and love it.
Set up is 9.8:1 83mm LSVTEC, stock port head, victorx intake mani with stock LS tb, full-race ramhorn, 38mm gate (will have to ditch for at least a 44mm), full 3inch exhaust.

Very good turbo for a 100% street car. Here is my buddy's car that I tuned on 91 Octane and timing is conservative. This was using a stage 3 and .48 A/R. Very simple set-up LS/Vtec with GSR head and only pistons and rods.

^^ how many psi was that on and was that on stock sleeves????? ^^

But can the 60 trim produce more power than the 57 trim on higher psi????? Basically the 60 trim is a little more laggier???I'am getting a little confused.

Heylookits shawn

my scanner doesnt work so i had to take a picture

basically stock b16 with type r cams and blox intake manifold.

Both turbos are identical other than the compressor wheel. The difference from a 57 trim to a 60 is the same as the difference from my GT3255b to a 57trim. The difference again being a different sized compressor wheel. The 57trim uses a slightly smaller wheel than does the 60trim. The difference in spool wont be very noticeable; similarly, the overall power potential of the two turbos doesn't vary much. The 60 trim will have a slightly wider compressor map and be able to give an extra 2-3 lb/min more than the 57 trim. That translates into about 20-30whp IF you max it.

To bluntly answer your question, the 60 trim will make a little more power than the 57 trim at the same boost level.

^^what fuel grade??

lambertincorp

93 pump gas 2 1/2 inch dp and full exhaust

What 350Z??? He saw the Intercooler and it was curtains... And wassup with your boy moe pouring smoke off the tires and banging 2nd in the parking lot on 11psi... haha he likes it...

K Built... Its a Dynasty...Here comes 450+

19.5 psi on the street

Joseph Davis

84.5mm GSR with ITR cams, SC44 w/ the stage 5 turbine wheel. Wastegate (edit) 13.5 psi vs 26 psi:




Here's the same car on high boost with a 100 shot, the pull was done vs wheelspeed as the optical pickup used likes to flake when an engine twists around in it's motor mounts; the peak power was at 7500 rpms and is the point at which flow across the turbine chokes:



The bitmap screenshot of the datalog on that one is pretty amusing:



I'm pretty sure I could finesse things by removing fuel past 7500 when spraying, maybe support a steady peak of 600 whp across the stage 5 .63 AR turbine; but that's pretty much the limit of efficient flow across that hotside.

dc2turbo

what manifold was used with the sc44?

Joseph Davis

Mild steel tubular with a wide angle merge that John @ LHT in Tampa made years ago. It's nothing special except for being a great crack free manifold for a number of years now. I have pictures of it on Goforth's CRX, which made 541 whp on SC44 and 60 shot, but it's changed hands since then
