VVEL Cracking?
 

A little new to the tuning aspect of things but everyone keeps mentioning how the Z will be able to get a lot more power once someone cracks VVEL. Can anyone explain this?

Is it along the lines of cracking the timing so it can be changed?

yes. Its electronically adjusting timing to make the most power at every RPM.

Isn't it adjustable lift? Does it also have the ability to vary valve timing?

yes and yes

I predict that once VVEL is cracked all the guys who traded there Z's for 5.0 Stangs will trade back. :stirthepot: LOL

:bowrofl:

GTM is working on it.

I'm guessing at least another 10-15 whp is hiding in VVEL tuning...

Coming some day soon to my z.
But it will be a long time till its ready
we will just have to wait for sam to release it.

So if and when they crack the VVEL. How will the program be offered? Will it be offered as a reflash or can the program be run through Uprev? Seems the VVEL would have to be more of a personal tune if anything. Not sure. What do you guys think?

:roflpuke2:

^^^I bet he drives another 1000 miles to get his Z back ;)

ZR1 maybe. :bowrofl:

Realistically, after full bolt ons and tune, how much could VVEL add?

I'm guessing F/I applications will get about a 50hp gain.

Well what does a 5.0 put down? Times that by 9 and you will have the hp for a fully bolted Z + VVEL tune

that means NA is gonna be pretty pathetic...5-10rwhp at the most....many people are waiting for this like the 2nd coming of the Z....i really hope its not a let down

I think people need to stop thinking this is going to be some magical thing.
It will be a very nice addition for tuning both NA & FI, but just one item.

5-10whp would not be that bad, especially if you can just change it in your existing UpRev tune. I also heard it could be like putting a mild cam in the car, some I'm sure it will help alot down low and add some much needed torque.

10whp NA is a pretty big deal IMO

true, i guess my hope were just getting ahead of my common sense

is this for VVEL tunning or adjusting?

I could possibly see the adjusting producing decent gains

I mean, I would take more, but I really doubt there is a whole lot left on the table.

I dont care how much HP we will gain after we install GTM VVEL control

what i really care about is, I hope they release it before the next generation of VHR comes.

Yea, it could be an alternative to adding aftermarket cams. With whatever they adjust.

I agree. Everyone always talks about "when Sam finally cracks VVEL" like it's the second coming.

The main thing I think it would help with is improving the low-mid range driveability of the car, which in stock form is fairly anemic.

+1, all its gonna do is help with lower and mid end on NA cars. Might have the most promise for SC cars...

I'm a lot more concerned with that aspect of the car rather than peak numbers. I moved to the Z hoping for more juice in the midrange.

And before you say it, yes, I should have bought a mustang:rofl2:.

^ should have kept your 9 sec S2K!

Problem was it really wasn't much fun to drive unless it was on the dragstrip. Even on the smoothed out street tune, it had no power below 5k, and then too much beyond there.

The guy that bought it from me found the same thing out, and he's swapping out the turbo for something much smaller.

:iagree:

wow thats crazy! my only real hopes for this car is be in the 11's NA

You should be able to get high 11's N/A now without any VVEL changes.

Look at Jnaut... if he runs a drag slick he'll be running 11.8-11.9. That's probably going to be the best an N/A 370 can do.

thats what i was thinking, need more seat time...

what are your plans or hopes for the 5.0?

Just want it to be a good all around DD for now. With a good tire and a tune I should be high 11s, so that'd be pretty nice for a mostly stock car.

When I pick up another car I might SC this one.

so is it stock right?

all stangs hitting dealers now are 2012's the new boss 440 hp.we need a 400Z or turbo 370z from factory.

I'm like 1 second away from that stock, but a second is a long time at the drag strip. Full bolt ons, drag radial, 4.08 gears, pulleys, better torque converter, and a tune should put me there I think. I will probably end up doing all of those except the gears and drag radial. Hopefully that will get me mid to low 12's with good weather + track conditions.

you gotta do gears man! the funnest most rewarding MOD hands down

300rwhp just isnt enough anymore

last i checked, the turbo kits on the 370z are already capable of making the engine put out more power than the engine can even handle with a stock block.

'cracking' VVEL isn't going to be like getting a new ECU in a turbo car. its not gonna be like 'bam 30-50+whp'

our cars are tuned pretty well from the factory and already eek out most of the power that the motor has to give.


oh yea and:
