Its suppose to be in the lower 60s all week!!! Definately top down driving everyday and I hope I am able to make it to work everyday :lmfao: Unfortunately though, I will be out of town for a few days starting on Friday so I hope I take delivery before then and get in a few miles to break her in.
Thanks everyone for the kind words, as I get closer and closer, the anticipation only gets worse!!! It has now been a little over 3 months since she first went under the knife.
It took me about 6 weeks to gather up all the parts required to build the bottom end. Some of the wait was because of supply issues, some of the wait was because I wanted to hold out and get better quality parts and some of the wait was because I didn't want to go charging parts left and right. I paid as I went on almost the entire project thats why it got spread out a little more. What made it a tougher was the fact that I had just paid for my TT and install a month before. From there, the machine shop took an unprecedented month to finally bore, balance, blueprint everything. After that, my shop has had about 3 weeks after they received the block + parts from the machine shop. My performance shop doubled checked everything from the machine shop and built the engine. Although I know my shop has had my block for three weeks, they also managed to build Todd's bottom end on his engine too.
Luckly I was able to buy the main/head studs, AAM fuel return sys and Pauter rods from Julian. Thanks again.
So after the break in period I will be tuning it for the following.
Since I have new Tial wastegate springs set for 11.5psi and I have the ability to have two more settings with my boost controller.
So, when I end up tuning it the first step will be to tune it for 11.5psi. Since I have a compression ratio of 8.6:1, I would expect to see around 400-450rwhp. Then I plan to boost up to 15psi, which I hope will break the 500rwhp. This is based off someone's hp numbers from a different forum that had boost set at 13.5psi and was getting in the upper 400hundreds/lower 500s. I can't remember the exact numbers. Lastly, I really don't want to be the first guy to go past 20psi or go past 550rwhp. I will leave that up to some other daring individual that hasn't been away from his or her Z for so long. I think I will be able to break 550rwhp without going over 18psi though. I have test pipes, a good exhaust and a completely upgraded fuel system. If I remember correctly, I think Sharif was once talking about the Greddy turbos being pretty efficient around boost levels of 15-18psi.
I will definately post some numbers once the dyno is done. Since Todd and I will be dyno tuning the same day, we are shooting for two or three weeks from this Saturday.
So close, I bet you can taste the exhuast fumes. Just a few more days, and you should be done.
Correct, the Greddy turbos actually reach peak efficiency right around 20-22psi based on the compressor maps and the RPM that our engine operates in. Although its a bit counterintuitive, turbo efficiency increases, and compressor outlet temps actually drop as the boost increases...up to the point of 20psi or so...at which point, efficiency drops, and outlet temps rise. All th more reason to get closer to 20psi.
Take your time, check for leaks, break it in..change the oil and filter...get the shielded crank angle sensor wire installed..etc..etc.. I am sure you will be thrilled just to have your car back.
Who is doing the tuning on your car? All i can say is be cautious and take your time.
My shop will be doing the initial tune on my Z and I don't plan on having them tune it past 15psi. But, I am leaving NM on May 1st and heading to Connecticut. I already have plans to stop by and have Charles/CJ Motorsports retune my Z for the lower altitude and up to 18psi ish.
