Well about 2 weeks ago I decided to dyno my GST for the hell of it.
You might need DIVX or a decoder to watch. My buddy hosted the video for me but he did it in AVI.

First run was the best numbers of the day. 275.2whp @ 26psi (HAHA - Really lean)
Second run I turned down the boost and upped the fuel. 266whp @ 20psi. (First run on the video)
Third run I turned down the boost even more cause I was still lean. 269whp @18psi.
Fourth run the vacuum line on the WG blew off and it spiked to 30psi (Got it on Video, didnt think a 16g could do that) BTW: I hate zip ties, from now on I am using hose clamps!
Fifth run I turned the boost down even more. 274.6whp @ 15psi. (Not bad. 11psi less and .6hp decrease
)
Made some various other runs but everything I did the numbers just kept getting lower.
Now that I have a fuel pump I need to tune and dyno again and see if I can get up around 320-325whp range. Well see, I'll make sure to post the next dyno video up here and see what improvements I make.
