VVEL and Jun cams
 

So now that VVEL has been unlocked, do you think more power would be able to be made from a mod like Jun cams? I don't really know how it all works, wonder if any knowledgeable member out there has any idea. Jun cams supposedly (according to Jun) make 15-20 whp which means it's probably more like 15. If VVEl tuning with Ecutek could push that to 20 - 25, it might be worth it.

i wouldn't mess around with them. boost your car instead of thinking cams.

I was thinking the same thing myself. If a person were trying to stay NA to it should only benifit right?

I'm pretty sure 1slow370 put Jun cams in. From what I've read, they stay open longer and are only helpful for NA.

1slow370 is overseas right? Did he ever post a dyno sheet? I believe there was no VVEL tuning when he did it also. Wonder how it affects sound as well.

1slow370 is right here in socal. He sold his car though. There was another member overseas that did the Jun cams though. Can't remember name.

Navyboy916. I believe he was in Guam.

oh, wait, he's the one who did dry sump and everything, there was a guy overseas who did cams too. 1slow's car had way too much done to be used as a gauge for the cams, plus no vvel as well I believe.

i think there were possibly 3 people on the forums who did it. 1slow370 and some other dude who was going to post up dyno's but not sure he got around to it, and maybe one other guy. let me see if i can find that post

A few guys did it. but I don't think anyone really had definitive dyno results form just the cams. Also, I am wondering more about how much vvel tuning would affect the gains form the cams from someone who understands how this stuff works better than me.

I would love to see results from doing cams w/ VVEL tuning. I wonder if it makes any sound difference

Im all for more power, but have you heard how it sounds with cams? Sounds like the car is about to die. I don't know if Ill be able to daily a car like that.

If you're referring to 1slow370s car, I agree it sounded bad, but he did a bunch of other stuff also.

Sounded bad, you all are sick to your head. 1slow made the most horsepower out of an NA set up, with minor time to tune the car. He made 360 something on pump and 371 on E-85. Granted he had one hell of an manifold to, custom intake, and shortie headers and exhaust, the cam was the only internal thing done to the car. Just seems like a bunch of haters in the group, He did something noone has done with this platform and made it work, unfortunately he came across some hard times and had to sell the car. I'm personally going to do ipp heads with the jun stage 2 cam etc... hopefully by next Z day at Z1 motorsports.

All we are saying is that we didn't like the way it sounded. That is personal taste. We never said his car sucked. It is the most impressive NA build to date. I am just saying I didn't like the sound and that it had a lot more than Jun cams done to it to use as a gauge of the cams themselves. As for your build, many will be interested in what the cams do for you now especially with VVEL tuning.

Hopefully not blow up. Just waiting on a manifold to come out, i know two in R&D one is cjm i cant remember the other company of the top of my head.

What are they doing with the manifold? SO you're planning on doing the manifold and cams? I was wondering if ported TBs and upper and lower mani along with cams and VVEL tuning could get me 30 whp/wtrq without making my car much louder.

Billet upper and lower for cjm, other company is doing r-35 conversion with the up and lower i believe. It might with a better flowing manifold and maybe bigger intake worth the ported Tb's, all depends on n the tuner. I would switch to ecu tek. Im going with ati damper nismo oil pump and raising the redline to 8k. Hopefully spinning the motor little higher will make more power.

But i need lth's and oil first

And oil pressure gauge

I'm currently waiting to make the switch from Uprev to ecutek. My car made 331rwhp: Stillen G3, Stillen UD pulley , Z1ported manifold, FI LTH, and FI Non Res exhaust.

Since then, I've switched to the Tomei TI exhaust system and I've got a ported lower manifold from Synergy that I'll install before the tune. Hoping for a mid 340 to low 350. And now that VVEL has been unlocked, the thought of the JUN Cam crossed my mind. But, I think I'd venture into ported throttle bodies before the cam.

Not bad idea. I'm n just gonna save my money and wait for a manifold to come out, and when it does im going to buy the jun cams and ipp heads, and hopefully by then I'll finda company who makes an upgraded valvetrain. How loud is your car?

If the manifold or ported TBs, and manifold along with Jun and Ecutek can get me 30 whp/wtrq without making my car significantly louder or rougher sounding, I'd probably be in unless I cave and boost before then.

Guess all that depends how good the tuner is to make those gains, turbo will quiet your car and give you 300 more horsepower lol. Lot of supporting mods comes with that though. Guess the golden rule is gotta pay to play.

I would be using the same tuner who did 1slow370's car and the Fast Intentions tt cars (the ones done by FI). Anyhow, I am considering boos,t but not sure if it's worth it to spend that much on a car I no longer DD. Plus I do like that linear building NA power delivery. My hope is

cams + 15whp/trq
Intake Manifold or ported TBs, and upper/lower mani + 10 whop/trq
VVEL tuning with Ecutek + 5whp/trq

= +30 whp/trq withotu gettign much louder or rough idling/sounding

Your gains are very aspirational

Yeah... hoping VVEL can pull those individual parts #s up to the higher end...

Have you looked at some of the boosted dyno sheets on here? I think they mostly look pretty linear to me. Just a lot higher! Giggles! I think that is because of the vvel system

1slowz had a sick manifold, thats where he made his power, as for the normal people who cant afford 1off part, I'd suggest if you do decide to do.the cams you might has well do some head work. Thats where the bulk of your power is going to come from, you should make more than 30whp with that mod.

Headwork sounds expensive.

Vvel just kicked in, Yo!

It's kind of weird that there is a DE 350Z that makes 372 NA, probably the only one, but none the less. The VHR should in theory have loads more potential.

If I could make 30-40 whp/trq NA for 4-5k without ruining the sound (IMO) of the car and how it idles, drives etc., I would be in.

That de had itbs and **** load of other work to reach that power level, the vhr that made close to that had bssicbolt ons and cam

By what you listed for your mods, can't be complaining about expensive. Ipp sells stage one heads for 1600.

If you do exhaust cams your going to get a more lobe sound. That's what makes those old muscle cars "lobe lobe lobe" big cams. But when you open it up, it'll scream.

If that lobe lobe lobe sound is form the cams, then I guess I am out for cams, that was the part of the idling sounds from 1slow370's car that i didn't like

That's one of the major reasons why people get cams, lol

The more duration the cams have. The more lobe you will have at an idle. A cam with 250 duration is a lot smoother then a cam with 280 duration. Also when you have more duration. Your power band moves up the scale, and you will have less low end torque. This is a general rule of thumb. With VVEL and other things that the computer can do. The computer can smooth some of it out, but not all of it.

From what I've read the cam starts to make power after 8k, so if your really serious about building an high rev motor I think the cam would be your best bet.

The cam specs more or less tell you where the motor will make power. Lift, duration, overlap, lobe centerline, cam timing. But with the new motors like the motor we have. The computer controls somethings.
