What gear were these runs done with?
Something I notice is that the 5th gen has a lightened flywheel. This tends to shift the powerband to the right and NOT AS A RULE OR ANYTHING, but from what Ive seen, lightened flywheels give lower #s for TQ. That would be PART of the reason why your MEVI mostly platteus (sp*) from 5600-redline, and his 00VI seems to barely start to make its platteu at redline, and why his TQ is less.
Im speaking from my personal understanding, so if anyone has a different view, please jump in.

the timing advance means nothing for the 5th gen as that advance is only for non WOT conditions below 2300rpm...after that the ecu goes into closed loop mode and reads off preset IG advance maps...and hence stock ignition timing...but the headers over y pipe might account for a good deal of the difference as well

My run was done in 3rd gear.
I think you need to re-examine the graph regarding your statement above (blue vs red).

Great comparo. To me the 00vi curve for these graphs seems like a pretty decent amount of avg. power over zack's. Don't know how much is from the headers. Both nice curves though. The curve i'm most interested in doesn't exist yet, 00vi, i/y/e (no headers) and good EU tune (hopefully where i'm headed next year).

can't wait to see dandy's new dyno...timing makes a huge difference on our 3.0's as you guys all know...and A/F makes very little difference...he already made something like 220whp...I am guessing with extended rev limit and a lot of timing, dandy could hit 240whp! that's up there with the fully bolt-on 3.5's!
and as to what nypd-arnold said, I have always believed that 5th gen's don't make 190whp stock...more like 180...plus you need to understand that zack added the mevi, and it has been proven that about 90% of the reason why de-k's make more power than the regular de engine is the inclusion of a variable manifold from the factory...with the de-k already having it, that huge-gain mod is not there for 5th gen guys to do...in other words without the mevi, zack would be hitting atleast ten less whp peak...

Assuming this is Arrons' old dyno.....
1)4G vs 5G engines have some differences internally.
2)He also has 19" wheels.
3)The axle back part of the catback was disconnected.
4)Dyno was 'skewed' due to incorrect elevation and SAE overcorrection.

Would you really say 90%? Or was that just a random estimate? I would think the differences in the cams would offset each other (better exhaust cams, not so good intake cams). I realize there's other differences as well, though...
#31
I am not claiming 240... I have said I was hoping to be somewhere between 230-240. We shall see... remember I do not have cams or a flywheel.
BTW.. to those of you that have PM'ed me in the last couple days about various things... I am not ignoring you, I'm just crazy busy this week and will get back to you as soon as I can get some time to sit down at the computer in an evening. The only reason I'm popping on here once in a while during the day is because I am going crazy doing budgeting at work and taking quick breaks...

I was thinking going the same setup as you dandy, I have another set of heads that a shop that has done vq35 heads that has already accepted my challenge in seeing how much more flow they can get out of them with a budget of only $1000 or so...but I don't know if I want to go through with it since if I were going to swap heads with ones that are raced out and go through all the trouble, I would also do jwt cams and valve springs...I wonder at what rpm my power would peak with cams and a ported & polished head?

Zack342 /98SEBlackMax /jenk01SE
Apexi filter with Frankencar Intake
2000 DEK manifold swap with ported upper matched to VQ35 Pathfinder TB
Aluminum flywheel
Warpspeed non mandrel Y pipe
CM test pipe
custom b pipe with stillen muffler
SMT-6 +8 timing and 13.5 A/F
15" BBS wheels with 225/50/15 tires (34 pound combo)
Weather condition was -
94.8 F
29.7 in-Hg
10% Humidity
SAE Corrected
Also the original motor had 173K and was not in the best shape.
Can't wait to go back this October and make another run, the new DEK motor feels aot stronger than the tired DE. Best run with the DE was 14.9 with a totally stripped interior, 1/6 tank of gas, and trunk stripped. This year I've run 14.5 with the full DEK and with full interior,1/3 tank of gas, and a trunk full of stuff. Both times I used the same tires and had similar weather conditions.

In my opinion you guys are not making a valid comparison for a number of reasons, the most obvious of which is that different dynos read differently. That and the fact that Zacks dyno is atypically high further invalidates the results for me.
