things to do before dyno day

Vnismo370z · 11-22-2013, 10:01 PM

Breather mods are finally done on the Z and it's time for a tune. I've heard that doing a spark plug swap and oil change are necessary before a dyno day. Any thoughts or recommendations on what I need done before going and getting a tune?

How many miles since the last oil change? Never heard doing the spark plugs is a must..

synolimit · 11-22-2013, 10:18 PM

Change the oil if close to 3k and spark plugs if you plan to be 100 more HP then stock or over 60,000 miles. Since you have a 13 I doubt you're over 60k.

1500 miles since last oil change total miles on the car 8500. I was doing one regardless since it would be due when I go in for my appointment. I just heard about guys burning plugs during a tune, and paying for plugs on top of the tune. I would do that before I go in.

Until you go FI spark plugs arnt needed IMO. You should change the oil just to be safe

You're good to go. I wouldn't change oil or plugs. Now if you was close to 3,000 miles on the oil, yes I would change it. Plugs, no. I've got 20+ dyno runs on mine so far. Plus 6 trackdays. All on the the same plugs.

I'm still on the original factory spark plugs at ~40K miles and lots of dyno pulls and track weekends. I picked up a replacement set because it's kind-of about time to just do it before they ever become a problem, but honestly they could probably go quite a bit longer.

I never looked at what we have but I know the ngk iridium IX plugs on my WRX were good till 60k. Being turbo'd they should be abused more but if we get a cheaper plug then 40k seems pretty smart to change them out.

I've been using Mobil one for oil, should I change it up or keep it?

(To myself, please lord don't turn this into a oil thread!)

I ran M1 and Redline. Based off of oil reports I've had done I like the formula of the RL better. It has a higher yield of an element that protects better down to a microscopic level. Also, even coming out of the bottle M1 is like water, when hot its worse. I like my RL to remain thicker and protect when racing or for the aggressive street driver since it won't shear off like "water."

Jordo! · 11-23-2013, 02:53 AM

Oil change only if close to whatever OCI you follow; otherwise, should be fine.

Mobil 1 is fine.

Plugs should be fine to 100K, give or take; colder plugs might be needed if you were going FI (i.e., turbo or SC), but not NA with bolt on's.

BUT -- do you have a baseline? If not, it will be much harder to determine how much you gained over stock from the breather mods (although you can compare before and after tune, of course).

What kind of dyno?
