Another stock block setup rolling out of the shop, Made some decent power out of this kit, as you can see the turbo starts choking in the higher RPM's and the power starts to drop off pretty fast. Car has a ton of torque and is a lot of fun to drive, we hope the customer enjoys it!

quick drop off, mine similiar but not so drastic, maybe the exhuast is maxed, is it the 2.5 aps? i got a 3" fabed up and kept tq level after 5k, and hp drops like 90hp between peak and redline, oppose to 150ish. weird.

Congrats, i like seeing all these aps st setups that have been comming out recently

curve looks different than mine...but congrats on the new system. my graph down there was done at 9 psi on 91 octane

just keep an eye out on the scavenge pump...oil tends to gunk up around the area.

i had a hose clamp pop off that connects the pipe from the compressor outlet to intercooler inlet. if you ever hear funny noises at high boost when you let off the gas, that check there.

This is exactly what I want. I know the aps turbos are garret but how big is that one GT28? ANything to do to smooth out that drop in power? 3" exhaust? Maybe build the motor and put a GT35R for 600whp

Nice build, but weird how the power drops off so much.....According to the graphs he has more power/torque at redline with his 8psi set up than he does with the 10psi. Really doesnt matter though as I am sure its still a blast to drive. Congrats to the owner.

Shows how much I know. Are most aps st kits gt35r? I'm so ready to buy this kit from a dude on g35driver only thing I'm worried about is the power drop. Anyway to change that? Don't mean to jack your thread. Sick car btw
