Even if we run his car again on the DD, its doubtful we'll get precisely the same numbers.

When we we publish dynos SZM mag., we try to do our best to be accurate and want to make sure the readers and manufactures of these products know that within reason, the dyno is accurate.

other thing to keep in mind is what Dynojet it will be done on...the new versions and older versions are completely different in the types of readings they give
I'm watching the thread with interest. I personally do not expect this car to hit 300 whp given the mods, but we'll have to wait and see tomorrow.

For me, anything is possible, My G35 has tottaly stock internals and has 525hp and has made 11.0@125mph (with video and time slip!).something a LOT of people called BS until I posted the video and time slip. So anything is posible

I've been looking through all the recent threads about both the UTEC and the Ultimate ECU's. It is obvious that when a car can be fine tuned in a Dyno, will achieve more power than one with a generic programming, i.e. the TS re-flash.
When I pulled 295whp in a dynojet, some members didn't believe it, so I had to go to another dynojet and prove them wrong
Maybe G will reach 300whp... and if he does; I WILL get me a UTEC or Ultimate, and wish for a little more than 315whp NA...

When correction percentages come into play so that someone can see an "ESTIMATE" of what kind of HP they might be making on a different type of dyno,there becomes conflict...I say just leave the Dyno Dynamics #s alone and let them read what they read, and run your car not your Dyno Slip, however 90% of people are looking for that big Dyno # no matter what.
I have seen great fluctuation from Dyno to Dyno..We made 428whp on a DD dyno and then corrected the car to 490whp Dyno jet #'s, then went to an actual Dyno jet and pulled 470whp..Then went to a different Dyno jet and pulled 498whp..So it really does not matter in the end, does it..My time slip does not lie and shows a 126mph trap speed at 12.0 with a 2.3 60ft rolling off the line with no launch..I know may car is fast and I dont need a Dyno slip to prove it, simply 1300 feet of open road..lol
A Dyno is simply a tool used to tune and test a vehicle in a safe controlled environment..

Dynojets are known to read high. They may not be accurate at all in terms of actual real world horsepower. But REGARDLESS of that fact for a very long time they were the most popular dyno in the USA... the Dynojet 248c to be exact.
The dynojet 248c is almost ALWAYS used with ONLY SAE correction (and when its not, you can clearly see this on the graph). OK so maybe the dynojet reads a little higher then real world... but at least that is a CONSTANT. With everyone DYNOJET 248C produced graph you can CLEARLY SEE that it was SAE correction (when applied) and when its at or near sea level you can always rely on an accurate comparison with another under the same conditions.
Now about my problem with the graph in this thread... First of all... all the owners/operators of a load dyno want to KNOCK the dynojet cause its a POS for all the reasons their load dyno salesman explained.
HOWEVER they feel the need to try their best to emulate the dynojet numbers anyway. So their dyno salesman pops out a percentage that happened on a random test vehicle between their dyno and a Dynojet. Now all of a sudden we are supposed to believe that a Dynojet will always read 13% higher then a Dyno Dynamics? That is horse****. I dont care if you have examples, cause there are examples that prove otherwise just as well. Some will be 13, some will be 5, some will be 20. There is no way that two completely different machines are going to be a precise % different.
Then comes in the deception. On a dyno dynamics and other load based dynos, the owners/operators are jacking up their numbers because they feel short handed by the shadow that has been overcast by the Dynojet 248c and our expectations. HOWEVER they DO NOT CLEARLY SHOW on their graphs that this "DYNOJET EMULATION JACK UP" as been applied.
So now while they have everyone convinced their dyno reads LOWER then a dynojet, they have their graphs jacking up the numbers to god knows what, without even clearly stating this on the graph. So now its like "WOWWOW my car made XXXrwhp on a DD which always reads LOWER then a DJ and I have no idea that this is after an unorthodox correction factor and even tho I am a totaly cool guy and totaly respectable, I have NO IDEA wtf is really going on here. Oh hey look at this I broke all the records."
SHARIF and CP RACE have admited publicly in the past that they apply this percentage to their graphs. So I do not have any beef with them. But the beef I do have is with the, pardon my language, IGNORANCE that will float around as a result of the graphs produced with these non-SAE correction factors that are not CLEARLY STATED. With a Dyno Dynamics graph, you have NO IDEA what you are even looking at. How do we know if its a 13%, 25%, 0 %???
So to make it clear, i have NO PROBLEMS with SHARIF, Forged Internals, CP RACE, or the owner of this car. I am simply calling BS on the RWHP of said vehicle because I have enough evidence to personally believe that these results are not fairly comparable to other 350z.
Prove me wrong on Thursday, and I will gladly apologize and congratulate you... if its that easy to get 313rwhp out of these cars, then the entire community is to benefit, and I am all about benefitting the community.
Thanks for reading and please take no offense to what I feel the is the most logical understanding of this. As always, correct me where I am wrong... I know that I dont know everything (not yet anyway )
EDIT: HOWEVER, even if the car makes 310 or so rwhp on the Underground Racing Dynojet 248c... while I will step back into the shadows and eat my own words, I COMPLETELY understand if ALBERTO wishes to FURTHER DISPUTE the results!

So no one really knows what the Z is capable of with this tuning method. Even the utec has started to show decent numbers but as time goes on I think that everyone is going to be suprised by what the standalone or piggyback ecus will do
I seroiusly wouldn't mind to see that number on my car though... a very nice number!

congratulations on the new world record!!!
j/k, i am sure your car would make over 300rwhp on a dynojet... surely with all the great modifications you have.
#133
Charles.... you read it wrongly ... it was... 285RWHP.... and I was trying to calcualte the engine power with the 20% drivetrain loss... so that.s 285/0.8 = 356 (Engine power, not the wheel power).... and 285RWKW = 209.5rwKW as I stated previously.. sorry for the misunderstanding

And to add to the confusion, they have even changed the way Manufactures rate hp at the crank recently thus 287hp at the crank 3 years ago is not the same as 287hp at the crank now.
It is getting harder and harder to have true bragging rights. I guess the good part is it allows many of us to feel like our cars are running special. Bottom line is come Wed., if it dynos over 300hp, he will get his 15 mins of fame and Alberto's nuts will get a lot of pain.....

Phunk hasn't got it wrong, he was just pointing out that if your HP figure (achieved on consevitive calibrated dyno) had a +13% correction factor added to it, it would be a record for a NA motor on our forum. And as our forum has members from around the world, that makes it a world record.
Well I think thats what he ment

And seeing our forum is mostly Yanks, Aussies & couple from the Middle East that will count as a world record by me

But Peter, you have got the highest one I would say... with 214rwKW+ on your N/A race car...

Subscribing.
The class of 03 has been waiting a long time for this. Fellow Z'rs that have thrown the kitchen sink at the Z and not hit 300.
Performance Nissan guys
Crawford Guys
Aussie's
Z1
Looks like a stack deck. We will see.
