Wierd. I got 242.6, 228.1 with 2 runs w/ RT Cats, JWT Popcharger, Grounding kit and UR SS Pulleys. I'll probably just do another pull after I install the new Ingen exhaust.

 

I agree with that article, I think there is another thread around here debating it.

It is common knowledge here that the 350Z keeps gaining HP on successive runs. During it's baseline run my car gained 14 rwhp from first to last of 4 runs! This is perfectly in sync with what Steve Dinan was talking about with BMW's. The 350Z engine management is so advanced that it continually adjusts during each dyno run to maximize performance. I also agree with the lack of real-world airflow. I've always been puzzled how people claim gains with intake modifications when these dynos are always done with the hood open and fans blowing on it! Is that real life - hardly?

As has been said before, the only thing you can do with dyno runs is compare your car to others that day, or give you a relative idea of what mods are doing for your car (except intake mods).

 

If you want to squeeze a little more power out of your setup, try some cams. They seem to be the proverbial icing on the cake for people who have a lot of NA mods and want to stay out of the forced-induction market.

 

yeah, it does make you think about dynos in general. It should also make you think more of N/A mods in general, cause they are the ones that are the most dependant on the velocity of air coming into the engine, on the intake side at least. Of course, there are not a huge amount of mods you can bolt on from the intake side N/A. In FI, the system is compressing the air, so the dyno could be more accurate there, of course, their intercoolers cooling less will also lessen the power output of FI without the high velocity incoming air, so it would make less power too.

Like jng said, really you can only compare numbers on individual mods with similar conditions on the same dyno. The numbers aren't totally useless though, unless you have a boeing jet engine hanging around your dyno to make your numbers higher, lol.

 

I have JWT pop/catback/ground wires and I pull (slowly but surely) on my cousin with no mods. My friend has same setup as me but with the UR crank pulley also, and he pulls on me (slowly but surely) Mods are doing something my friend pulls quite nicely on a stock Z, I don't go by dyno rwhp, stick to real world gains you'll be more pleased

 

I'll tell you what, you gotta love that torque curve! And the hp curve is so linear...what a great motor this car has
