I'm not really interested in cats....when you have catless pipes let me know hehe. Unless the is no real drop in performance between the test pipes and the high flow cats...

Yeah I can do a non-dyno video just driving around the streets or something. Test pipes are available too .

Weighed the entire car today. Camera battery was dead so I didn't take any pictures though.

Car:
2009 Nissan 370Z Touring w/Sport Package (No NAV)
SPL Pro Rear Camber Arms +3 lbs. over stock.
Berk Technology High Flow Cats -10 lbs. over stock.
A little over 1/2 tank of gas. No driver.
The spare tire and tools were not removed.

3,326 lbs. total
Cross Weight = 49.9%
Left Side = 49.9%
Right Side = 50.1%
Front = 54.7%
Rear = 45.3%

heavier than i was expecting.. ^ although with the touring package i guess this is still pretty light. thanks for doing that DDM

[M.Bonanni]

Yeah a bit heavier than I thought too, but it is what it is. This weight is more real world though with 1/2 tank of gas, all the floor mats/spare tire/tools/etc. still in the car. I am doing track prep on Thursday and will re-scale it with all of that stuff removed.

Thought it was worth mentioning that the cool a$$ spare isn't in every car. My spare is a solid steel wheel.

Ahhh, probably only in the sport package to clear the calipers...

Looking forward to Thursday's results. Thanks DD.

Change of plans, track prep won't be done until tomorrow. I was originally supposed to go to San Diego and back tomorrow to pick up my time attack 350Z from Jim Wolf. I was going to run the 370Z on the track Saturday and the 350Z on the track Sunday for some datalogging on the Haltech ECU.

The forecast calls for rain and JWT isn't quite done with the 350Z yet so I am going to leave it down there. I will still track the 370Z rain or shine, but that means I have all day tomorrow for track prep and I am feeling lazy tonight .

Track weekend was a complete failure, sorry guys. It started raining last night and the forecast said it would be worse all through the weekend.

I decided to leave the spare/sub/tools in the back to help keep more weight over the rear wheels and aide in traction in the wet conditions on track. So sorry, I didn't corner scale the car with the spare/sub/tools removed.

I also didn't change the brake pads since I was worried that because of the conditions and the lower speeds of driving in the wet, I wouldn't be able to get the track pads up to their operating temperature. So I have no feedback on the Hawk HP Plus pads .

I also failed on the photos/video. We were the first group out on track in the morning and the track was really wet. I didn't set up the video camera because I knew I was going to be going out and going super so I can see where the puddles were on course and check out the conditions. After finding the trouble areas of the flooded track my intent was to start filming in the second session. Well the weather got worse and wasn't letting up so they canceled the event and sent everyone home before I got a chance to go out on track again.

So in closing, it was a day full of fail. I have no feedback on the car, no feedback on the brake pads, no video, and nothing cool to share.

I was by mother nature. Its a slim chance, but I will do my best to make it out to Streets of Willow for another (hopefully dry) track day on the 13th. Sorry guys.

That's a shame... Well, there's always next time. Thanks for the update. We're glad that you tried, but we're more glad that you didn't push it to unsafe boundaries.

Thanks for the update. Hopefully the weather lets up and you get to test the crap out of the car.

I was excited to do some wet weather driving because we rarely get to here in Vegas and driving in the wet is a great way to really improve your driving skills. It was just too much water and puddles this past weekend. I was instructing with the student group and they were the last ones to run before they shut the track down. I went out with a student in his car and it was nearly impossible to just make it around the track at that point. Some of the puddles...or lakes...stretched across the entire track and were pretty deep so you had to really slow down to not hydroplane off into the weeds.

Sounds exciting!

It really is too bad you couldn't go out on the track again. Hopefully it won't be raining next time. I think I'm going to sign up for a trackday thats coming up soon too and I'll let you guys know how it goes.

Also Mike, about the battery. I was talking to someone yesterday that knows a good bit about cars and I told him about changing the battery out and putting it in the trunk. He said that that's not such a great idea because of the smaller battery/longer cables issue. If we switch the battery out, it has to remain at the front. If you want to move it to the back, then you need to get a strong battery or keep the stock one.

I understand the logic behind that, but from personal experience, it works just fine. I have the same Odyssey PC680 battery mounted in the trunk of my 350Z and it fires up just fine.
