Im finding out that my car hates dyno's. The numbers mean nothing to me. My HP curve and trap speed is all that matters.

 

lol at dyno's are useless. How else do you plan on getting your car tuned right? Sure the track is importantly, no one is arguing that but a dyno serves as a health check for your engine and an invaluable tool for tuners.

 

I didn't say dynos were useless for tuning. But as a measure of power, they are useless. To see what you gained throughout your powerband over stock band, dynos are good. To throw out WHP figures as if they mean anything means poop. =)

I think AJ's fully modded Z dynoed 255WHP, yet his 1/4 times and trap-speeds don't reflect that.

 

Track times have an infinite list of variables. The controllable ones would be things like track prep, tire type, and of course driver. Not many "modded" Z34's have run track times. There is one guy with 4.08's on a 7AT with exhaust intake running 12.8 which is ridiculously fast on stock 19in tires. Eventually later this season stock and bolt on z34's will be running at the track more often, someone is bound to throw DR's on the rears and considering that sport package wheels are 10in wide a right set of tires could get a stock Z with an exceptional driver 12.9X. Dyno's and track times are the two most important and accurate measurements you can get on a car...I couldn't see that Z at T&R running anything but high 13's if that even with DR's.

 

This is why I listed trap speed as the most important factor. It is to me, anyways. Especially here in NY (much of the East Coast, actually) where we're at sea level, so we get the full potential out of our cars.

 

239RWHP is not what it was putting out and the dyno is an inconsistent tool to measure HP and torque across different states, elevations and run conditions. /thread

 

Fail of an answer. It put out 239whp, that was the highest of 3 runs, made a cool sound in the process . Who knows maybe this could translate to a 11sec quarter mile, many of you are suggesting that HP numbers are meaningless (I agree to a point) and traction is everything. The conditions were good, the dyno was fine, so really dude get with it.

This thread has NOTHING to do with track times, when I get to a track and I get to see how things so with my own eyes I'll be sure to get a thread on that.

Anyone know what's the highest HP reading for an N/A z33 thus far? Has someone hit 350whp or more? What mods?

 

The highest I've seen thus far is in the 330 range, on a tough dyno. I'm still waiting to see what Gabes 4.2 build will turn out.

 

wow stroker kit, that's sick! Personally I love the VQ motors as is, I wouldn't want a stroker but I know those who do it make crazy power, even if they don't rev as high. I would rather build on what I have but 330whp is really good.

 

I was just informed by one of the members from nycnissans.com who was at the event, that the Z was a DE, not a HR. If that is really the case, then I can see that happening, and that T&R's dyno is not at fault.

 

Thank you for clarifying my error, dude told me it was an HR

 

Yeah I dynoed 257 on a DD in shootout mode and 247 after my osirus tune on a Dynojet. It sucks telling people my real HP but as long as my traps are where I want them to be I am happy.

 

Thats what I figured.

 

Please search.. There's even a sticky.
400wtq -On stock block.
^but there is no guarantee...

 

I was right.

Blaze: You either misunderstood, or the owner of the car doesn't know the difference between a Rev-Up and an HR, and told you it was HR. People think "High-Rev" and "Rev-Up" are interchangeable. They aren't. The only way to tell is dual intakes and a 7500RPM.

BTW: You aren't the guy with a red 370Z, are you?

 

Anyone know of a high HP NA HR? I don't remember seeing one. The builds are alway DE's (rev-up and non rev-ups)

 

What do you consider high?

 

As am I.

And Mr. BladeZ34:

a) Don't call out fail on my posts when it's important to know that the HR is not going to post numbers like than unless the conditions are horrid. Sorry on behalf of the forums for our rude demeanor and not believing your false information.
b) If you were as much of a connoisseur of Z cars as you're saying you are, it would have been easy for you to tell if it was a DE or an HR just by the first glance you took at the car.

So really dude, get with it.

 

Considering they dyno around 260'ish I would consider 300+ high.

 

Because we f*ckin rock?

It's actually amazing how many people think HRs started 06+. Everyone always thinks I have an HR, and I have to tell them it's not, that I'm just a lowly DE. People forget that the hood bump on HRs has a purpose, and that it's not just cosmetic. Of course, the other chunk of confusion stems from the "Rev-Up" and "High-Rev" monikers applied to the VQ35 engines.
