If you were at the top of X gear and then floored it, do you think you experienced your VDC kicking in without knowing it?

I guess I'll say it but yes, the Z feels significantly slower at hot oil temps. Running the car WOT at 180 vs 220 has a very very noticeable difference in acceleration and throttle response. I thought I was hallucinating so I performed a series of tests and my theory was correct. Like someone said, the Z really hates heat. In cold, it is such a champ tho.
I've owned an AP2 S2000 (the faster version in a straight line). The S2000 is a quick little car but you should definitely have beaten it by a big margin. When I used to run my s2k against 350Zs, i would slowly pull from away from the DE motors (03-04) but the HR ones (07-08) would completely OWN me. Not just once but exact same results with multiple cars and even driver changes. The 370 and the s2k aren't in the same performance class anymore, and i actually believe you when you said you couldn't pull away because at 260 degrees, my Z feels slower than my s2k felt. |

I think once I re dyno Ima ask if I can get a 3rd single pull on the dynojet and get the oil temp near 260 and put it on the dyno. then we can all see once and for all if its the case.

Ok well here the vids are. For everyone saying they dont see high temps heres what I see very day.
Here is a daily drive through a back road to work. I was in 5th gear the whole time. Video was taken after about 15 mins and the speed was from 50-70; 60-65 being the average. Here is a shot at night obviously. Watch the oil temp move jsut from 2 pulls. Imagine if I was a track and always about 4k rpms... and the optimum would be at least 5k. Here ya go. Only a few pulls and look how high it is. This was take only a few mins of driving after the one above. There is something wrong with my car for it to be increasing in temps so quickly.

Oh i believe you about the oil temps shooting up. On my way home I drive up a steady incline for about 14 miles in traffic and I see temperatures easily reach 220+ on a cool day. On a warm summer day, I can get the needle around 250.
The engine heats up pretty fast. So loss of power due to heat soak would not be surprising.

first off i have gotten the engine hot so i believe you, second if i'm going over 50 and cruising i'd be in 6th not 5th you'd be suprised how much that effects your oil temps. when your cruising around try keeping your R's right around 2 not 3 thousand it will help considerably. i save the higher revs for when i'm having fun or racing it otherwise i stay low so that when i do want to screw around it's fairly cool. I can say that on a long road trip doing 73 on cruise control in 6th it stays right around 220

If they slow down too and still won't let you pass, you can pull a .45 on them and that will distract them (because they'll have to look for their 9mm), meanwhile you can speed off and activate your stealth tech and get away. Only one of those comments is sarcastic. |

Either way, you think you're above the law. Thank you for being the problem instead of being the solution. |
