so if a stock 2012 was in the 28x whp
that mean this 342whp isnt too exeptional afterall...
I went from 256 to 324 without VVEL tuning which is 68whp more and let assume Mike had exactly 280whp as a baseline.. he got +62whp up to 342whp
the biggest difference between him and my setup is the oversized TB other than that the rest is pretty similar.

We have never dynoed a 370Z that only makes 256rwhp. That's 350Z HR power. What dyno was used? And believe me there is more than oversized TB which Mike doesn't have.

that 256whp was done on a dynopack which is on part with other 370z.
vq35de were about 215 on that dyno where I used to go. (sg-motorsport.com)
anyway

I was just comparing the gain from both dyno.
the end result isnt as great as they look to be ,,
im not bashing anyone here.

the big point I was showing up is only the gain on each dyno , not comparing a dyno to a different dyno which cant be the same.

Still to many variables was this 256 run the absolute first run?

from what I remember I did 5 base pull and all of them was within 2-3whp up and down which bring the average to 256.

again im just comparing the true baseline to the end result .

doesnt matter if Mike has a 6MT and I had the 7AT .. gain is gain.

if you used a dynapack those read higher than dynojets.. so your 324 would actually be like 298whp per dynapack themselves compared to a dynojet.

actualy when SG closed I did a Dyno vs Dyno (same day within 2 hours) (his dynapack Vs a dynojet) it ended at 324whp dynapack and 321whp dynojet

so that 324 whp was from the same dynapck that when I got the baseline.. you read the thread wrong and didnt do any research before trying to bash on this.

all number I gave here are SAE not STD

330whp STD was on the dynojet as per one of my first thread in this post.

oh and if you meant that a gain on a dynapack is actualy lower than a gain on the dynojet becase the dynapack are known to read higher

first; you are wrong, a gain is a gain no matter what
second; read my previous post about my dyno test
third; a dynapack can also be set to read lower than usual .. its all depend how it was setup in the first place.

Megan is right, typical average gains are in the 50 - 60+ whp across the board with the typical mods Gen3, ART/LTH and CBE. This is without touching the VVEL.

gtypical gains for those mods are not 50-60whp... LOLOL where are you even getting that.

find the examples you speak of.

look up Megan's profile, and anyone else running the long tube headers, Gen 3 and CBE with a tune.

It's worth it to take some advice I heard once from a very wise man about how to compare dyno numbers.

If, for instance, we choose to compare mike's gains to yours, say...

(342-280)/280~= 22.1% gain

(324-256)/256~= 26.6% gain

The SAE guys need to develop better corrections for their estimates...

And this is why I'm always loathe to compare numbers.
