yeah and that tq dip at 5100 should resolve itself, they reset the ecu learning points so thats basically the cams not being aggressive enough. it should flatten out again after a few driving sessions.

+1 rep, thanks for posting all that so fast.

Thanks esfourteen for all the information and time you put into this. Now go get something to eat and enjoy your Z!

I think since ur the most modded so fsr and tuned. Tony should pay u to just go redyno next week after youve driven it for a while. See any diff

lastblueprint · 10-08-2010, 04:42 PM

How many pre and post dyno runs did you do today?

Boost_lee · 10-08-2010, 04:55 PM

Id like to see tonys opinion on this, but I'm wondering if you would see gains if you had the stock intake installed. I could have sworn I read an article where a 350 saw gains switch when it swapped back to stock intakes while running MD's art pipes and exhaust. Granted, I don't recall what kind of intake it was running, maybe it was just a bad design on that car.

Thanks for the dyno sheets, numbers, and the super fast install/dyno time.

interesting..

Motordyne · 10-08-2010, 05:11 PM

I would have preferred to see more same day pre/post dyno pulls to equilibrium to be sure.

One baseline run may indeed be valid but it would be better with more runs showing repeatability. When you are assured of repeatability you are assured of the pre/post accuracy.

Note: If anybody does same day pre/post dyno testing of any part, weather the numbers are moving up or down, dyno each condition until it no longer moves and then get your three runs for each pre/post condition. This will give the most confident test results.

This is the way I do all my dyno testing.

klubbheads · 10-08-2010, 05:23 PM

Those are great results IMO... That top end Power can be easily fixed by a simple retune on an actuall dyno not preprogramed maps inserted in with Osirs.

My personal opinion is that car is running pretty lean approaching redline because of more airflow (plenum) and not getting enough fuel to make the power that it can..

Nick,

Let me know if you would like to do this.^
If there is any kind of change or adjustment over time, at least we will know if it does.

I would have no problem re-testing it if you want to cover the costs.

I'll call you Monday and we can work out some details, I have no problem do any additional testing with more dyno runs.

Motordyne · 10-08-2010, 05:58 PM

Yes. Lets do it.
Just drive in and dyno the same way as when you drove in today.

Capture all data on a email or flash drive and also get several of your previous baselines to compare to.

I know this is less than ideal but more data is always better. Maybe something can be learned from it.
