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.

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

VTR uses a dynojet, a dynojet and a mustang with the same results should tell you something. Mustang dynos typically read lower than dynojets, this one doesn't. You can either accept that the dyno reads high or keep trying to explain to everyone else how you made so much power, up to you.

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.

Very true. This is why a lot of the higher hp guys (Supras, Vettes, Porsches, etc) like to compare 60-130 mph numbers. It eliminates some of the traction issues you could get when doing 1/4 mile, 1/8 mile or 0-60 mph testing. I say some traction issues because there's not much you can do if your car puts down upwards of 1000 whp.

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

Im actually going to get re-tuned on thursday ill post my dyno

TonyBPD · 03-29-2011, 10:40 PM

My old 2004 Ford Lighting put down 486/510 on a Dynojet. 11.88 @ 114.49. That was one hell of a ride......in a straight line at least.

that is all 60ft there, probably high 1.5 or low 1.6

but nice run!

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.

That difference has gotta be all due the VVEL.

Dammit. C'mon GTM -- bring out that VVEL controller already!

Oh and whoever thinks they're putting down 330-340 NA... yeah... that's an awfully optimistic dyno.

Maybe at the crank

BLM · 03-30-2011, 06:03 AM

We need an insider from Nissan to leak the VVEL info to GTM. Can't wait until that is available!

I'm somewhat surprised there's not a Euro "Nismo R" model that has some sort of forced induction from the factory. Maybe in the future? It would be able to obliterate the Cayman S and run with the M3 and still cost less...

Glad to hear that Jordo, saving this argument for the future Nismo bashing threads
