how much power does your car make and how much does it weigh!? never seen such a gutted Z lol

BTW, what are those 3 gauges for?

 

~265 whp
~2750 # + me
oil pressure, oil temp, wide band

 

Think you guys will like this one.

nice!

must be a long straight, unless I saw wrong it looked like 140+mph on that straight?

 

it is a LONG straight, but my tires are a bit shorter than stock too, 295/30/18 verses 245/45/18

That and a 3.91:1 Final drive means I shift_ALOT

 

yeah when you hit 6th and stayed on the throttle I figured you have really short gears.

 

yeah anyone with a 370Z that would like to trade ring and pinion I'd be tickled pink. The 3.74:1 would be a nice trade for my 3.91:1

I might call Mike

 

just get 4.08s

 

I'm already shifting enough, that would make the gears even shorter, going with the 3.74 would make the effective gear ratio closer to 3.99:1 verses the effective 4.18:1 running the 3.91:1 if my math is right. All of this due to the shorter tires, back when I ran the 295/35 tires the 3.91:1 was effectively a 4.09:1 and that was nice, but I'm digging the Yokohamas for what I do.

245/45/18 circumference = 83.81"
295/35/18 circumference = 82.05"
295/30/18 circumference = 78.41"

245/45/18 gear multiplier = 83.81/83.81 = 1.00
295/35/18 gear multiplier = 83.81/82.05 = 1.02
295/30/18 gear multiplier = 83.81/78.41 = 1.07

therefore
245/45/18 | 3.52*1.00 = 3.52:1 | 3.74*1.00 = 3.74:1 | 3.91*1.00 = 3.91:1 | 4.08*1.00 = 4.08:1
295/35/18 | 3.52*1.02 = 3.60:1 | 3.74*1.02 = 3.82:1 | 3.91*1.02 = 3.99:1 | 4.08*1.02 = 4.17:1
295/30/18 | 3.52*1.07 = 3.76:1 | 3.74*1.07 = 4.00:1 | 3.91*1.07 = 4.18:1 | 4.08*1.07 = 4.36:1

And now that I have such a tall gear, I can't find a 35 series R comp, i was awesome with Street tires, and I was pretty dayum quick with street tires, now I'm like a nissan ad shift_alot, LOL

Sunday fun day with NASA TT. Competition was over on Saturday. My best time was a 2:34.5. The noise you hear under braking is my massively warped rotors. My lap timer for some reason has the start finish a little ways past the start finish, but it is spot on with the times. They match the transponder times. For some reason the lateral G's seem backwards too. Watch the meter during the carosel on the last couple laps. It gets way over there. Weather was beautiful and the scenery was amazing. All the trees were changing colors.

I just found this funny. I got stuck behind a guy who refused to wave me by.

Man, I do not miss HPDE at all. I used to hate that. I know you were being safe which was good, but I when that used to happen to me I would get closer and closer to let them know they need to get out of the way. Even if that guy thought you were slower in the corners, he should have let you by on the straights. He should know your is much faster in a straight line. Hopefully you had some better sessions later that day.

 

Yeah, like I said in the videos, I was about 23-24 seconds faster per lap. But had some sweet chases with a SUbaru Sti and Cayman R later in the day.

Open lapping at TMP, what do you expect. I give them once chance to let me by and then I just take it.


Lightning: How are those mirrors attached? Are those the APR ones?

That's an awesome pic.

I am still wanting to post vids on here from Nats. I recently realized that I will not have data for my fastest lap session.
