just wow ,i had to put this here .

the raising of the dicplacment and the comp being raised from 10.6:1 to 11:1 and the VVEL make for a huge increase . and imagine when the VVEL is tuned

o snap

 

WOW.

Cliff's notes: 365bhp, awesome toark curve!1

I vant one...

 

That is impressive. I can't believe how flat that torque curve is, just like an LS1. More than likely my next car....

 

The LS1 dyno's i've seen are ALL mid-range. Torque curves look like camel humps. They just make so much more average torque than most motors anyways so nobody really cares. This 3.7's is more like an I-VTEC torque curve, loooong and flat and that's damn impressive for a larger motor.

 

Sweet... man that VVEL would be nice to have!

 

The next motor to go in my S13 is a VQ38 with VVL if I can get my hands on one in 2-3 years! Awesome find krismax.

 

torque numbers are a bit depressing but the HP numbers and flatness of torque curve make up for it...wonder what will be in the 2012 z, when im buying my next car

 

thas almost 100hp/liter wow thats impressive

 

Borrowed from our own .orgness..

i like the hp but the tq seems a bit sad to me...but its flatness is a nice thing to see.

and ls(?) dynos usually just have a tq flatness to them through out.

 

Hard to believe a motor without variable ANYTHING has a flat torque curve throughout. It's a mechanical impossibility, regardless of displacement. Not a knock on it at all, so don't get defensive in your next post, but I'll stand behind my previous statement. They look like camel humps. Low-end is good but doesn't quite match the HUGE mid-range torque which drops off at higher revs. Anything but flat, stock at least. Everything I've seen tells me the stock LS1 was tuned for mid-range torque. Don't want to get too far OT though. This thread is about another great Nissan innovation.

 

why you son of a bitc...nah im just playing, most i have seen have benifited from huge tq low end and carrying that same mostly through out...it does drop off higher up but thats mostly a cam issue than anything else. i am happy for nissan and this motor. if this would have been in the first g35 i wold have bought one in a heart beat....maybe i might end up with one with this powerplant. though it sucks for people who bought a 07-03ish g35 and got the "crappy" vq lol

 

one thing i noticed is this car was driven with AC on heat soaked to the dyno and tested .

i would bet people get higher #'s than this

and i believe the 08 z will get this engine ,because nissan has said this tec h will trickle down

 

I thought you hated variable valve timing technology and thought it was useless...





















BTW the ECU has a cut feature that turns off the compressor during agressive throttle angles or revs.

 

So whats the next motor going into the max!! I want to do a 3.7 swap.

 

Ahhh, but with new technology, such as VVL, comes many more complications to your swap.

 

VVEL. Variable Valve Event and Lift. I concur though..This is some pretty high tech stuff that would not be easily modifiable...a full swap might be possible but good luck on that journey...

The VQ37 impresses me and I can't wait until its release. I definitely want to feel the power delivery on that thing

80% peak torque at redline. Looks pretty flat to me... sure you weren't thinking of an LT1?

/OT

 

That's not an LS1 dyno...but w/e...

 

umm... OK

 

ls1 dyno

http://www.dragtimes.com/2004-Pontia...aphs-9875.html

that is more flat then what the vq37 can wish to have

 

http://www.internetautoguide.com/car...gto/index.html

 

Anyhow, that LS2 powerband is from 2500-6000. The 3.7's is 3000-7500+. You do the math.


BTW, whenever the air/fuel graph is included in a dyno chart the HP/TQ curves end up squished and look flatter/smoother than normal. Just an FYI.

 

The GTO has an LS2. Either way, I digress. Useless banter, really.

 

04-05 has ls1

06+ has ls1


its ok your the mod of max.org all motor section...the rest of us follow other cars as well













(feels the thump of the ban stick)

 

even ls1 vettes have the same tq platuoe(sp) and they can rev up to 7k easy. and the 3.7's is up and down...more camel humpish if you ask me

 

Fine, ya got me with the LS1/LS2 model year jive.



Either way, I still don't think the LS1 comparison is valid simply because its effective operating range is smaller. The 3.7 torque curve is flat for LONGER. If the rev-limit was raised to 8k it would still be making good power up there.

 

-2k4 goats had LS1s.

-80% peak tq at redline. For reference, the VQ37HR has ~84% peak tq at redline.

-I'm not sure how your powerband comparison is relevant, but the chart is from 1500-6000rpm if you look closely, and it almost completely flat. Either way you look at it, there is a 40ftlb fluctuation (13%) between 1500 and 5500rpm on a car that peaks at 320ftlbs.

 

uhhhhhh VQ35 swaps are now what, oldskool?????

psh, i wonder who is gonna be the first to swap in a VQ37. we must first aquire a FWD version

 

Yeah, it'll be interesting to see when they start putting them in the FWDs.

 

ZOMG.

I'm not saying that LS-series engines don't have a flat torque curve. I'm just saying it's not an apples to apples comparison to the 3.7 because its relative power curve is much broader, IMO. This motor should be compared to the M3's, GT3's, NSX crowd IMO. High-revvers with linear power delivery.

But you all can continue to dissect my posts and miss my overall point if you'd like.

 

3.5 swaps running off of 3.0 ECU's are.

According to nissan the 7th gen max has an ace up its sleeve. Hopefully it's a HR or an HR variant.

 

Dood. You said Ellis Juan = camel hump. I said "not exactly." It's pretty simple.

 

Show me a graph without the a/f at the bottom and I'll be glad to make nice.

Wasn't revved out FTL.

 

Jesus, you're insatiable. Check the post again.

Just in case it's still too flat, here you go.

 

No RPM on that last one?




Just givin' ya a hard time is all.

 

I believe it's called "dragging your feet." Pshop it yourself if you don't trust me.
