question to 2007 and up Z owners

have you dynoed your stock or modified VQ35HR yet?or what numbers do you think the HR motor has stock to the wheels???

Stock= approx. 260 rwhp with 15% drive train loss. Torque is more important which most 6 cyl. lack.

In internal combustion engines, Torque and HP go hand in hand. Increase torque at any given RPM and HP at that RPM will increase accordingly:

HP = (Torque x RPM)/5252

That being said, a low peak torque output in a motor is not all that meaningful either. Higher RPMs provide more mechanical leverage for a given amount of torque via the torque multiplication that occurs through the gears in a transmission. Ignoring any frictional/mechanical losses, 150 lb-ft of torque at 10,000 RPM will produce as much torque as 300 lb-ft of torque at 5,000 RPM if they are producing the same wheel speed. It's not by coincidence that each would produce the same HP as well....

All this quote from some tech book and still does not answer the guys question!

I have seen 260 to 275 whp most of those being around 265.

Is this some kind of attempt at an insult?

I don't think so. But you sure sound funny, because after a paragraph,you still didn't answer the thread starter's question.



I have seen numbers from 265 to 275 in different forums. You have to remember that there are numerous factors that affect HP. Humidty, the type of Dyno machine...in other words take all the numbers you see with a grain of salt. but don't worry, it's widely known that the new HR motors are special. High response...vroom vrooorrrrrm m<-theres an r for the reverb from the exhaust

...or maybe you secretly want an S2000. thats something a Honda owner would say.

It wasn't intended to answer to OP's post. I was simply addressing a statement about the "lack of torque in a V6".

i own an '07 350Z...now why would i want a ****ty honda????...Z 4 life
