NA: 342/275. Anyone higher?

MJB

335whp with stock exhaust manifolds and with HFC's... hmmm, thats a very generous dyno.

You didn't read my post correctly. I now have HFC's but those numbers are with Test pipes. I expect to be making less now with HFC's but that doesn't change what I made. And the Dyno I was on wasn't some cheap a$$ Dyno you may see towed into car shows and probably never maintained or calibrated either. Here's a link to the shop I go to. And do some research on Dyno Dynamics Steady State dynos too and see if you read anything about them being generous.

But either way a Dyno is tool used for tuning and I did my research and supposedly steady state dynos are some of the best bc of all the options it gives the tuner to calculate load with and really give the tuner the best capability to give you a custom tune for not only peak power but for drivability throughout your rpm range. And I feel that's what I got, increased power and a very smooth power curve and the car drives better from it. The number that printed out to me was just a bonus as long as it was higher then what it was originally

I don't think I lost to much from the swap. I needed to have cats for state inspection. No emissions testing where I am but cats have to be present. I have been pretty happy with my setup.

Lol, so you don't think I know anything about a dyno or tuning just because I think your numbers are alittle high? Trust me, I know that Dyno Dynamics tend to read low, thats why I'm even more skeptical about your 335WHP...You don't think its odd that you don't even have LTH's or shortys with heat soaked style intakes, yet you have numbers higher than 99% of the members on here? Any dyno can read high. You do know they have to be properly calibrated right?

No need to be defensive. Hey, its a forum, discussions and debates is why we're here right? As long as your Z was tuned properly and you can feel the gains is all that matters

I know they need to be calibrated and yes I even questioned my own numbers that day. I posted before that I even said something to the tuner and he was surprised bc he has done many uprev tunes in Z's. He said they keep up with the maintenance on the Dyno and use the same correction all the time. So I have to believe him I suppose. I also have to believe that being in an indoor Dyno room with huge exhaust fans and front fans running its also optimal conditions as opposed to being in a hot humid open shop bay. It was hot a$$ day in June in VA and it was cold in the Dyno room. Also maybe my car just liked those intakes and exhaust combo with the test pipes. I mean I guess I can do some runs on a diff Dyno for comparison but I don't have TP's anymore and why spend the money if I'm happy with my results. Not being defensive all in good conversation I figured I would participate in the thread given its title and my results given i came close w/o headers or vvel tuning

best thing to always do is go to a dyno day with many other 370z's.

If the dyno reads high or low at least you can compare to where other z's are sitting.
