Hello all new Z owner from Canada

[Aspectinc]

That is todays project and hopefully that answers some questions. I did find a YouTube video of a yellow z doing a dyno pull with the same setup. That car was running 4.5psi of boost and made 400hp at the wheels. The is nothing for information there and the video is 12 years old. So I’m curious to know why it was setup like that when I have seen countless other pieces of information which say it should make 500-500 at the wheels. My car is running rich so I am also going to swap the spark plugs with GTR plugs and see if that helps. The nearest tuner is 3hrs away so I am going to do what I can before taking it there.

The GTM stage 1 kit made ~8psi boost. The stage 1.5 and stage 2 should make more than that. If you’re truly making only 4psi you have a problem.

I discovered my BOV was not closing. I have since cleaned and oiled it and am now marking 7psi of boost. I still have to adjust it a bit but it’s working much better then before. I just bought the car so it’s taken a bit of time to go through things and try to see what and how things have been modified. The car is still running very rich though. I appreciate the help and any advice.

I’d also recommend a BOV rebuild kit with new orings. Wouldn’t hurt. Pretty sure the stage 2 kit should easily make over 10psi of boost

Do you know what pullets you have? I can't imagine a pulley setup that would make 4.5 would be used. 400 wheel on that boost seems really healthy i wonder what fuel. I'm using an ATI Super damper and a Kraftwerks pulley to get 10-11 psi at 7300 RPM, that's making 470-480 wheel on 100 octane. I need to do E85.
