Default STS to Trick swap

So I finished the swap and headed to the dyno on Friday. I still need to fix a few issues and work on the tune a little but I got some comparison numbers. I have attached the dyno sheets for comparison. The STS kept up better than I thought but look at the power under the curve with the faster spool time.

Low boost off the wastegate spring
STS - 7.75psi
Trick - 6.75psi

STS - 405/419
Trick - 400/430

More boost

STS - 12psi
Trick - 12psi

STS - 544/571
Trick - 559/622

Final pull

STS - couldn't load past 12psi on the dyno
Trick - 14.5psi spike and settles to 13.5psi

Trick - 610/660

I need to figure out why the boost is dropping 1-1.5psi after it spikes but I'm pretty happy so far. The uncorrected numbers today were 627/677 so it feels very good on the street. Also the last pull was run #104 on this stock Lq4 and it keeps on taking a beating. I might switch to 3bar and see what it will take.

this is certainly a great comparison! I'm guessing the Trick kit isn't a rearmount?

Trick is a sponsor on the truck site that makes front mount turbo kits for gm trucks.

I'll try and get some tomorrow and post them up. It's a really simple setup that uses the stock drivers side manifold and a crossover under the engine that connects to a log manifold.

Engine is a stock junk yard LQ4 with a Z06 cam and good valve springs. Turbo is a Turbonetics T76 BB with .96 exhaust housing.

I actually bought my kit used from the white truck that ran 10's on their site.
It is the high mount kit.

Cool, so it's the T76 with the large compressor housing and not the smaller TC series?

Yes, it has the big t series compressor housing. I thought I had a TC until I saw one the other day and realized how much smaller they are. I could make a lot more power with this turbo but this is my daily driver so I'm trying to keep it in one piece. LOL

Any idea why your STS setup spooled so pathetically?

I have 3.73 gears in it. The .81 would have helped spool time but it chokes it up top so I had the big housing on it.

I don't have a chart but the iat's are about 35 degrees higher with the front mount on low boost. I run meth on high boost so it doesn't matter.
