Dyno'd my 6-speed 350Z today.

First run - slightly heat soaked engine
229.8 rwhp & 231.0 rwtq

Second run - after letting cool in front of fan
235.6 rwhp & 237.0 rwtq


Car again is a 6-speed, was dyno'd in 5th gear (1:1) on a DynoJet dyno. 1740 miles on the car. Air temp ~53deg. I mixed in 2 gallons of 100octane on approx 6 gal of 92 octane Amoco to help reduce any possibilities of knock, but did not drive a round much to allow computer to compensate for it. I followed break-in procedure till about 450miles, then gradually eased into full throttle runs by 600miles or so, then open season after that...

Second run numbers were about what I expected (though I hoped to be in the 240's).

I'll post a pic of the graph monday when I can scan it in.

Does anyone know what the average results are (stock)

We got 243 on a dyno jet but the car had 4500 miles on it, probably need to let them break in a little longer.

The guy at the dyno shop said he typically see's LS1's and others increase their rwhp by 8-10 or so after about 6000-10000 miles. So yes my engine is still a baby, but has a decent amount of miles to get some baseline numbers on. I need about 100lb.ft. more torque to be satisfied....

Yep you got it must have seen my Z down there. Were working on some intake mods at Sunbelt also.

Hey Doug,
I wish I had know you were at Sunbelt. I was at Balanced on Friday . I would have stopped by to say hello.
How is it coming with the intake mod ? I am really interested in this .

The car was actually down there a couple of weeks ago. They were working on moving the strut bar so we can make the intake plenum taller. Could take a couple of months to get everything done and tested but I will keep everybody updated. Good to here from you.

My guy uses the a Dyno Jet too and he has said the same thing about the numbers, he said about 5k miles though for LS1's.

In fact a friend gained .3 at the track in his famous "Orange Crush" WS6 stock just by driving it a year, no mods!

trying to post it...

McDan

Allright, this 200k maximum size limit is driving me nuts! I can't post it. I'll try a little bit more later.

...I think anything above 235hp is good, especially at such low mileage. Also keep in mind that at different locations, conditions are different. Thus if you are comparing your dyno at a high altitude vs a low altitude, or temperature, or moisture, or type of dyno, etc they are not exact comparisons...

also, which wheels do you have? I have lightweight 18lb enkei's.

McDan

Stock 17" wheels. Stock everything else, except the addition of 2 gallons of race gas.

blackS

...yes, but SAE calculations are not going to be exact, as you cannot account for every single variable with 100% accuracy. Also keep in mind that most people expect to see above 240whp to be 'satisfied', that is only around 5whp different from what a lot of people are getting... that is around a 2% difference (.02) factor...that could very easily be made up or taken away on small differences in the rounding of your decimal points in SAE adjustments for example...what I am trying to get at is that, as I originally stated, is that if you are around 325whp then you should not be dissapointed at all....
