I know the car comes with 287hp to the crank stock, but what is it to the wheel? anyone knows?

 

From what i heard its like 252 or something like that, I know someone out there knows the actual numbers

 

250 is a little high for stock, though possible. ranges are generally from 220-245

 

all Z/s are different. I have seen them as low as the 220's up to the 240's I don't remember seeing any in the 250's stock. Most are in the 230 range. My baseline was 238

 

There are a bunch of guys in socal that recently did a dyno day. You can see the results in the Southern California section of North America. Basically, they found out that there is a major variation in wheel HP for stock Zs (as much as 15 or so), but most likely, the stock wheel HP should be from 235-240. One other interesting thing that they found out is that some guys who have a few engine/ecu and exhaust mods actually LOST horsepower, or were making less than other guys with pretty stock setups.....go figure.

 

Well 235-240 is cool with me

 

230 - 255 is what I think. 247 - 255 are factory freaks, 236 - 246 are normal 350z's, and 230 - 235 are slightly underpowered 350z's.

 

my dyno at the wheel was 237 rwhp

 

wow its still pretty good 237whp but don't you guys its a little to much loss? 50hp from crank to wheel

 

Oh yeah, and I forgot one more thing......some guy put a NISMO wing on his car and laid down some pretty good dyno #s.....gotta get one of them.

 

look at my siG..."auto"

 

i dynoed my Z at 239 rwhp 237.42lbs of torque bone stock

 

How much does it usually cost to dyno a Z?

I imagine it depends on the area, but I'm curious.

 

with injen intake and nismo exhaust i dynoed 242,242,244. No baseline though.

 

It varies from car to car and from dyno to dyno. I took all the stock MT dyno results from a dyno results thread and averaged them - it came out to 236hp and 230tq.

Obviously some charge more than other, but the type of dyno you use can influence the cost. I had mine on a dyno-pak (I think that's right) and it was about $80 for two pulls along with some print-outs and tuning suggestions

 

Those of you who baselined around 237-239. How did you guys break in your motors?

 

Normal driving for about 1500-2000 miles. By normal I mean no real heavy acceleration from a stop.
