So I have to ask: Should we run, skip or scurry to the nearest dyno with breathing mods in hand to see the best results our Z's ca possibly have? I don't think of it as cheating. I think of it as best case scenario, and a true measure of our vehicle's capability.

:tup:

I guess that means it's Dyno season. Get your Dyno runs in now so you can put higher numbers in your sig and gloat all next summer when people are doing pulls in the heat :)

Doh someone beat me to it.

Really, it doesn't matter though. Temps are just yet another among so many variables that make dyno comparisons between different cars and dynos pretty much useless. The dyno number is just nice for comparing your car to itself before/after changes, on the same dyno in the same weather and fairly close together in time.

If anything you probably don't want to Dyno *Tune* in the cold winter weather as you'll get more timing out of it than you can use in the hot times. But then again, our car self-tunes timing anyways, so that probably doesn't matter much.

I just don't like how long it takes the car to warm up when it gets this cold. Makes it harder to hit my mpg target. :shakes head:

Just curious, how do we know when your cars are warmed up? I usually wait about 35 seconds for the RPMs to drop close to 1k then drive slowly out of my parking structure. Is there an official indicator of when we are warmed up enough?

I do the same on cold mornings. I will let it idle for about 30 sec. or so until the revs drop to ~1krpm and drive it normally. I won't push it hard until the oil temps are at 180, then the fun begins. :driving:

When the oil temp reaches 180*F you are good to go. Before then keep the revs low. Not only is the oil cold but it's also under quite a bit of pressure.

With an oil cooler, though, it's hard to hit 180 on short drives especially in cool weather.

You need to fabricate a cover for your oil cooler. You want to block off at least half of the rows in cooler weather so you can get the oil warmed up.

Is the 180 mark important for normal highway driving where I stay mostly around 3k and below with the occasional punch for accelerating?

I can agree with this, i felt the same way about a lot of CAI's, that's the reason i bought all of the silicone hoses available,including the post MAF hoses ( of course, i didn't need the breather hose set). I'm very glad Z1 Motorsports had that nice black friday sale, ordered the K&N air filters too. Now all i'm waiting on is delivery of my girl Vanity.:happydance:

Yes you want to get your oil above 180 even in normal driving. If you are making quick trips obviously there is nothing you can do, but if you are in the car longer you really want to get those oil temps up above 180 for sustained driving. And you want the oil warm regardless of how long you're driving if you plan on revving the car at all.

Okay, thanks. Are there any threads about fabricating something to partially block the oil cooler?
