Car and driver tested an 06 and said is was an 07 this has been covered Hundred of times.

The nice part about the HR is that it is over 250whp from 5800rpms - 7500rpms.

 

5th gear is the 1:1 ratio, and that is the best gear for a simple power test.

 

oh ok that explains the misunderstanding

 

interesting would like to see at least another 4 cars dynoed before making a full assessment. However, I would like know how we can get of the HR motor to get some power.

 

Car and Driver would probably be in a heap of trouble by other auto manufacturers that probably help them financially if they posted a 13.6 et 1/4 for the new Z. So they baby it down the track

 

Not an '07. Look at the hood.

 

I did notice that, but figured they used the wrong picture for the site. INSTEAD OF THE COMPLETELY WRONG YEAR CAR!!! HAHAA

 

Also remember WHERE C&D tests their cars --- usaully at higher elevations in the heat....they always run slow times and suck at launching

I tend to give more credibility to the real world stats on time slips as long as all the info is on it

When you know the true elevation of the track and temp and humidity you can get an accurate look at the ET's and traps

Sea Level vs 3000ft is a big difference in ET ---- all things being equal almost 4-5 tenths difference for an NA car

If you look at the traps though the Z gets a higher trap speed after every round of power improvements --- even with the extra weight that means more power is being created for sure.....104 trap stock is nice

With a strong clutch and sticky tires I'd like to see what an 07 will do in cool temps at a sea level track....

 

The Car and Driver article was a misprint. It was actually an 06 and I refuse to go through the entire explanation. If your interested just search as its been said numerous times.

Btw the best stock 07 Z time is now down to 13.45 sec.....

 

Even that 14.2 for a 06 Rev Up seems kinda high...should be around 13.9-14.0 But it could be a heavy model

 

I should have my dyno sheet scanned shortly.. but my best pull today on a stock 07 HR was 260whp/235tq on a dynojet. Not too bad really.. Right after that I installed the nismo exhaust though lol and crawford cats monday... I'll re-dyno then and post a sheet to see what's up..

Either way this car is a lot of fun!

though it' a gas guzzler!

 

^^^ It's only a gas guzzler cause you're a lead foot! Like me

I will have my 2007 HR dynoed soon as well with before and after test pipes. PLEASE post the results after Nismo exhaust and crawford cats...Ive been waiting to see the results of previous years exhaust mods with the new 07 Z. I cant wait.

 

yes, and i will be dynoing it!!


hehe, springs should be here tuesday....

 

Actually I believe VeeTec is now down to 13.3x with his '07.

 

Yeah but you guys have all the mods... we have exhausts/cats..

When a pop charger or cai comes out for the car, I'll run that as well but that's bout it for power.. i just want a car that handles badass... so my work is focusing on subframe, sway, strut bracing, and full suspension + wheels/tires.. then safety, then exterior, then power if i ever decide to go that route..

And yes I have a lead foot and I live in stop/go traffic... just ask nextstage.. it's hell out here in houston traffic and he's boosted!

 

Yeah i was going with test pipes.. but it's just a pure pain in the ***... i like the crawford cats a friend of mine has them on his 06 and they give the car a nice growl, mixed with the nismo sounds like an enzo or other exotic sports car.. (drooooool)..

My thing is I'm going for Euro styling, so it's all subtlety for me...but either way i'll make sure to post the #'s/sheet asap.. cats should be in the car monday night/tues then ill dyno again this weekend...

Guys,
Doesn't anybody remember that all the close up pics of the car they tested look like 06 without the bulge in the hood? Car and Driver took the exact same numbers from the 06, they have never tested the 07. I had an 06 and now an 07 and i will tell you first hand it pulls harder.
