I don't know why people think the 06 is such a pig compared to 03-05. It gained ave of 149.5 lbs, after running some numbers. lbs/hp is nearly identical.

yeah but I guess the logic is like this:

"I can add 15 horses to the crank fairly easy, but how the hell am I going to lose 150 lbs of something I'm not quite sure I needed before??"

 

Actually, those are 10.8 lb/hp for the '03 and 11.0 lb/hp for the other. The lower, the better. Therefore the '03 should still be better using this figure-of-merit.

Another way to look at it is that the weight went up 6.4%, but the HP only went up 4.5%.

uwaeve

 

Hahaha.....11hp per pound huh? That would be 36,300hp. Try 11lbs/hp which equates to more weight per hp than the 10.7 calculation.

 

Looks like you're a few tenths ahead of me as well....hehehe

 

Sorry for being dumb but what is MREV?

 

They're heavier yes, slower not so much. The extra weight will be a disadvantage on a twisty track, but the new motor is prolly a little better even though you lose some torque.

 

Yah I removed my spare and tools and I agree with you on 1 & 2. I also got the HKS exhaust with is 15lbs lighter than stock so thus far I've lost 55lbs :-)

 

+1

 

MREV is a mod for the 300HP rev up engines. It is a 287 Lower plenum + a Isothermal spacer. The shorter runners on the 287 plenum bring back the torque on the 300 HP model.

 

so it brings back the torque and they lose hp up top...? i mean if thtas the cause the end up with a 2003-2005 modeld 350z with a spacer and technosquare reflash for the higher rpms, but they are 150 pounds heavier. how does that work out? (if what I just said doesnt make sense please ignore it since im kinda dumb with all the technical aspects.)

 

Helium in tires?

Be carefull!!, don't put too much helium as your car will fly away and you probably don't have rudders to steer it so you could crash into the 3rd floor of a building!!

 

You're little off. Crunching more numbers,

Diff +.02 +.01 +.02 -.01 Ave +.01 lbs/hp

% wt gain 4.74 4.66 4.71 4.50 Ave 4.65
% hp gain 4.53

So the difference is so small its negligible. 06 Track actually has better wt/hp ratio than prev years except 05.

The weight will affect handling and braking more. I bet 03-05 will have better lap times around a track.

 

I have heard from many people that the Rev-up motor takes to bolt-on mods better as well. So with a few mods, that can make up for the little bit of torque.

 

You lose a tiny bit of hp like after 6500

 

what is causing the 150 lb weight gain. That is pretty signicant (about 5% of total wieight).

 

HA i knew that nismo exhaust felt like more power

i have over 36k HP!!!
