05 LGT dyno


Recommended Posts

I went into this build hoping for 400's. 5 minutes with Brad at Engine Logics told me that was not going to happen with this turbo. The first run was done at wastegate spring pressure and a minimal tune to make the car safe to drive to Engine Logics. I am happy where it is for now, but will probably be looking for more soon. The power level feels about where it was on my first build of the Legacy (before I took it back to stock to sell.) After getting lowball offers, I decided not to sell and make the car what I wanted it to be. That is where we are now.

 

I also started with a transmission issue, that is NOW SOLVED. Brad said he had experienced the same issue on 350Z and G35's. It turns out that the load scaling being modified from stock throws off the TCU and causes shifting issues. Back to business. There were no real issues aside from one small vacuum line coming off of the evap system.

Car on Dyno

Some random run along the way. I suck with a camera phone so the final run didn't come out clear.

Not sure about the under 60 but it is a bit of a dog on a launch from idle. My car tends to down shift when I want to go fast, so really it isn't bad for most driving. Next step is getting to the strip. Once I have solid documentation on this I'm swapping compressor wheels... Maybe even turbine wheels. Staying journal bearing to save on costs though.

The 20g with the 8cm hotside is what is killing your launch, but being an EAT car you probably shouldn't launch it really hard. Make your time on the back half of the 1/4 mile once that 20g is spooling.
