So after a few times under the car and a few trips to Sears for some more tools, I finally got my test pipes on. It only took me about 2 hours once I figured out how to get to all the bolts, which really was not as hard as it originally looked once I got the right tools. My Z is DEFINATELY faster. My butt dyno says I gained at least 20whp. The sound is a little loud, but I am sure I will get used to it. I used to be able to get through 3rd gear without slipping the tires too bad, now I am slipping the tires in 4th a little and I have no gripping 3rd gear. Now I need 2 things, wider tires and a fender roll. I am pretty sure I can squeek 315's on my 9.5's, anyone know of a place to get my rear fenders rolled? I am not going to tackle this one myself.

 

sweet... might as well get DRs cause I doubt the extra width will take care of all that traction for you.

 

sounds like its time to turn the boost down for daily duty.

 

there goes street legal though..

 

What offset is your wheel? 315s will fit on a 18"x 9.5" without rolling the fenders if they are a +30 offset.

 

I am not 100%b sure, but I think I remember them being +23. I don't see how that would work because right now the edge of my tirews sit right under the edge of the wheel well.

Do you have VDC Mike?

 

Yeah +23 would not work. I do have VDC, but it is always off.

 

yeah his Z is much quicker and the boost is getting over 10psi now, should be a very interesting race this Wednesday night...

 

10psi? Is he on stock internals? How much boost do you run Rob?

 

10+psi is what my Zietronix is "quoting". I think because I have not changed the elevation settings from when I was in Utah, its a little high. Yes, I am on stock internals and the APS stock tune.

 

Mine creeps over 11 around 4k, then tapers down to 8psi from 5k to redline.
