Injected Performance 370Z dyno video, 258whp DD

Ryephile

The AFR's are a whiff rich for N/A. The chart shows mainly in the upper 11's:1, which would be perfect for a boosted port injected engine, but perhaps a tiny bit too rich for N/A. Taking into account E10 we all run, 12.7:1 to 12.3:1 should yield peak torque.

Thanks for posting the video and tidbits!

This Dyno is pointless. Its the only dyno of its kind the puts down such low numbers. Not even a mustang dyno will give numbers like that. There are numerous dynos showing the Z putting down almost 290whp, that is consistant to what the crank 332hp is putting out. If the Z was a 332hp car that only put down 250whp then the Z would 80+ hp to drivetrain loss and that is not the reality.

o but so wrong you are

see the thing is this dyno dynamics and mustang dyno's are 'loaded' dyno
they simulate the weight of having to move the car also!
so when you on a dyno jet and get your 290whp, thats just how much you can make to the wheels
when you make that power on a loaded dyno thats the power you actually HAVE moving the car.
also they are alot better for tuning because they simulate actual load on the motor and drivetrain better, providing more accurate tuning

Both of these are excellent when it comes to tuning. If I could, I would only get tuned on these. It may read lower, but I don't care about numbers; I care about accuracy, consistency and real usable power.

One of the better dynos out there for tuning is a dynapack, which just happens to read higher than most dyno's out there.

One of the many reasons why dynapacks are great is because they are very consistent. I have never seen that consistency from any other dyno. Not only that, but the fact that they read off of the hubs really shows how specifics mods affected your cars performance without having other variables such as a change in rotational mass (ie. just happened to get a new set of wheels that are heavier) skewing the effects of engine modifications.

I'm not saying other dynos aren't good for tuning but its great to avoid all those other variables when someone is tuning a car.

Speaking in general and not directing this to anyone... people these days care too much about "numbers", specifically peak numbers, without really understanding what they're really looking at.

i didnt speak on dynapacks as i have no experience with them

give me a break im only 19

What makes this dyno pointless? People keep on forgetting the main reason behind a dyno is for tuning purposes. Numbers are just numbers. What really matters is how those numbers change within the same dyno during any modifications.

A dyno is only pointless if you're just looking for a "number".

If the 370Z read 310 whp in a dynapack, then read 240 in a mustang dyno, does that make any difference?

I could not agree more. If you are really concerned about high dyno queen numbers, go find a high reading dyno. For tuning, as long as you have a baseline and a final number, most any dyno will do the job. How the numbers change before and after modifications on the same dyno is all that matters.
