Well, J's350Z and I went up to BM Tranny's DynoJet in Bound Brook today. My Z was bone stock, his had a custom earthing kit, the Jim Wolf intake and resonator removed. Here are my results:

First run: 244.2 HP, 246.1 lb.ft. - corrected to 238 and 240 respectively, I think.

Second run: 249.5, 249.7 - corrected to 243 and 243

Third run: 255.4, 250.5 - corrected to 249 and 249

Needless to say, I was very pleased. As for other info: about 3750 on the odometer, pretty cold day, like 35 degrees or so.

And I gotta say, Jason's exhaust just sings to you when it hits about 4000 RPMs. He'll be posting his numbers sometime later--

 

Good numbers. How did you break your car in?

 

What were J's350Z numbers?

 

Normal break-in, although I accidentally went over 4 a couple of times. About 1150 or so, I winded it out for the first time, and I'll be changing the oil for the first time on Tuesday.

J's numbers were about 8-10HP over mine. He'll post his soon I hope. I need to get my dyno chart scanned, because they didn't have the ability to email it to me.

 

Some of the strongest #s I've seen. Nice!

 

By the way, that third run should actually correct to 249HP and 244 lb.ft.

Out of curiousity, can anyone convert these to crank HP? I believe the standard assumption is 15%. Going the other way, multiplying by 1.18 gives 293HP and 287lb.ft., or 301 and 295 using the uncorrected numbers, as the guys there said I should use. Either way, not bad at all.

 

damn...nice numbers!
man..wats ur secret?

 

My best (actual run) was 267 HP and 261 TQ... I was very pleased. Corrected #'s were 259 HP and 252 TQ. These #'S are off the top of my head since my graphs are at home and I'm at work, but I remember that my car had 10 more HP and 8 more TQ then Daytona's car... What was amazing was how smooth my TQ was with the grounding kit compared to Chris's without it. I will see if I can scan the 2 side by side so you can see. It was about 25 degree's out and the test was done with a fan it front of the car and the hood open..... And BTW, I run Mobil 1 and have 10,000 miles on the car.......

 

Nice #s you two!
I did 246 whp Stock (corrected) and 259 whp w injen and resonator remove (corrected) I have 5000 miles on my Z.

 

Assuming 15% drivetrain loss, your #s would equate to:
(15% loss : 1.00 - .15 = 0.85)

249 / .85 = 292.94 HP
244 / .85 = 287.05 TQ

Which is exactly what you posted, although we arrived at the result different ways.

Either way, nice strong #s you two!

Just curious, what correction factor did your dyno use? SAE, STD?

-iboost

 

My best run "Actual" was 264.4HP and 261.1TQ....Which corrected to "STD" was 256.9 and 253.4 TQ. Like I said earlier, I was very pleased with these results!!!!!!!!!
I guess I'll see what I can get with a little forced induction. Oh, and I plan on installing an air/fuel guage/monitor to watch because the car was running a little lean. But I run 94 octane in it so I should be fine.

 

Great numbers. I wonder if all of us can expect the HP & TQ numbers to climb over time. I have read (in this thread) that the ECU is pretty conservative. Either that, or the grounding kit and Mobil 1 are making up the 10HP difference. At any rate, congrats! I would be pleased, too.

 

Nice numbers Chris and Jason. Did either of you scan the dyno graphs yet? I'd like to see the difference with the grounding kit - I have yet to install mine. Hope neither of you are driving the Z today with this snow.

 

Jill,
Didn't you get enough of me yet . I don't have a scanner but I do have them in front of me with a fax machine if anyone wants.. Email me or PM me with your # and I'll send them right over. It is remarkable the difference with and without those stupid wires....Oh, and BTW, I have Daytona's(Chris) and my graph both with me....

Just seems like NJ Zs tend to be a little faster than other U.S. Zs.

 

I think our "BASE" models run better on the wonderful air we get from the refinery's on the NJ Turnpike.....
Hey Chris, what exit are you??????????????????? J/K

 

I don't have a fax machine, sorry! Thanks though!

Mine is a "Base" too, this is the 4th time I see a base model doing better #s that the others models, in the track too....I wonder?

 

Shiiiit, the air up there is already about 85 octane. It can only help
