But once you download UpRev they all kind of become the same. And similar numbers are like, I made 339whp and chuck made 342whp. Esfourteen I believe mad the same or 1-2hp less. We all had CAI CBE some kind of TP/HFC and a Tune.

Look, I love the guys at performance, but the dyno reads high, I don't know if they do it on purpose or not. You need to stop stressing that your numbers were made on a mustang dyno because the majority of mustang dynos read LOWER than dynojets and you will just confuse people who are unfamiliar. Our cars made 340whp, but so would every Z on this board with the similar modifications. Theres no magic fuel/unicorn blood additives on Long Island.

These threads are basically useless because this is not the only dyno that will read abnormal, high or low. All that matters is delta, with basic bolt ons (intake, exhaust, hfc or test pipes) plus a tune, you can expect ~40hp increase over whatever your car made baseline. I would go so far as to say adding in a lightened flywheel and underdrive pulley you could get close to +50whp over YOUR baseline. /endthread

Well look at Black Nismo. After his TT install he dynoed close to 490 wheel. I saw on another thread that he took the car to VTR and dynoed like 496. What dyno does VTR use? Cause it pretty much matched the one at Performance.

Answers to this question are not going to give a clear picture unless the responses are isolated to one type of dynamometer using one specific correction factor (preferably SAE as STD tends to overcompensate on NA cars) and the vehicles are all dynoed in the same gear.

For example, some MT's dyno in 4th and others in 5th -- that affects the final numbers, at least on a dynojet. the AT will almost always be dynoed in 4th.

Also, many people like to report STD numbers, because they tend to be higher.

Finally, peak numbers can be misleading -- the Z has a tendency to show a spike in power as you approach fuel cut.

Even then, with everything done exactly the same way, expect some variance...

Numbers will be all over the place on load bearing dynos -- some Mustang dynamometers break hearts, others dont.

As far as peak power goes, Z's with some sort of intake, CBE, TP/HFC's, and tune will generally see between 300 and 310 on a dynojet. A bit more with LTH and pulleys. No clear difference between AT and MT.

Forget dyno talk and numbers. Dyno's are different. Numbers will be different. All seem to be within a certain range anyways. None of these numbers are going to matter on the street. The driver makes the car.

If you want a real comparison, then runs it down a drag strip and look at your trap speed, who ever is highest is making the most power. most stock z 's are around 103 to 105 mph, im @ 114.5

A dyno is more of a tool for tuning, imo.

^^absolutely!!




Show-off!!!!! :icon17:

Why not? The only advantage you hold with your "Nismo" at this point is a suspect adjust to the factory to VVEL. Which is just that, a suspicion. No proof, the only reason a nismo makes more power "Stock" than a regular 370 is because it has a freer flowing exhaust and a mild tune. But its still called "stock" lol...

I just took a good look at a bone stock Nismo dyno -- they DEFINITELY have more than just CBE and fuel/spark -- it must have different VVEL tune as well.

Regular Z's need a tune, CBE, and TP's to catch up to the bone stock Nismos.
