Can wait to see the results, I think any enhancement to the Z in N/A form past regular bolt ons is definitely a great thing.

How much did the cams end up costing you? This sounds like an interesting mod.

i'm going through the jun site, and it shows that the test was done using the jun cams and HI-comp piston kit, do i have to use this piston kit to yeild more results? and if so where can i purchase this hi-comp piston kit?

If by yield more results you mean see the horsepower gain that is show on the dyno graph, most likely, but then you wont know what power is coming from the cams and what is coming from the higher compression pistons.

And of course, adding the pistons will involve more labor as you'll have to tear into the short block.

that is true, we want to see what power the cams yeild alone, and higher copression pistons are a hastle to install im sure

Pretty much.

Yes Cam only gains please. I would not be interested in new pistons unless I came across some serious money.

sub'd this bitch !!!!!!!!

We spoke to JUN regarding a more "conventional" setup for the Z and what benefits the cams will provide.

On a car with only a catback exhaust, JUN expects gains in the 15-18 horsepower range (they specifically used PS, but the conversion is very close to that range). They didn't give any indication of what RPM range the power is added in, unfortunately.

Lets hope that stands to be true.

Almost 20hp is not bad. And I'm guessing the more mods the better? I'm not to concerned with hp but I would like some more TQ

I'm more interested in what the gains are after full bolt-ons.

Well yea that to. LOL

bingo!

I think this will be banging on a Turbo setup. More air in More air out turbos come alive quicker and torque to hp numbers would be closer. Id even sacrafic a few horse power to get the torque to hp ratio come together.

That is what I am hoping for with a CAM setup!

:iagree: This might go on my to do list for next summer after the rest of my car is done.

I just put a call into Z1 and i got them looking into it. If they think this will be any good which im sure it will I def will be looking into this. I think the vq37vhr has 600 whp potential without internals. lord help me if i get to 600whp lol

if I could get that number off twins and some cams I would be :happydance:

I have the turbos to do it i just need the cam. I would be stoked man

We have one in our area at 606whp. His username is Pquaid. He's at our Thursday night meets quite often. That car is a beast! I need to tell him about these

Id like to talk to him about his setup is he one here? I really need to see what he has in fuel upgrades?

Damn dude, you got my planning my forged internal setup now. If this pans out, I can work in cams when I do my internals.................

I heard a cammed stroked g35 on youtube i was like damnnnnnnn i want to sound like thatttttttt. I hope this will change the sound like that and mabe a little lop

Why? There is no point in having anymore torque than what's already given on a twin turbo setup on a stock block. First and second gear are already worthless and torque is what breaks engines. Maybe with a fully built motor and you're looking for Dyno queen numbers.

Yea your right BUUUUTTTT I can say I have it so its worth it to me and trust me the vq can handle much more then the 450 tq numbers my car is pulling with the stock block. Sometimes my 370 feels like its gonna fall on its face at lower rpms and the torque really isnt there much until the turbos come on. It would be nice to have more torque to get it going better before the turbos come on. Im not even sure if thats what this cam will do Im just hopeing thats what it does.

Mabe even a faster turbo spool because of more exaust. Im just guessing.

how much are these selling for???

Bump........

You're right about that, maybe "The White Dragon" would benefit with his 1,000hp :D

Thats a whole other monkey to tame there lol

I been in touch with Circuit Concept from Japan, its their z34 that has been tested with JUN exhaust cams...here's part of their response

Hello again

OK
I understand.

But for confirmation, I would like to explain.

Nissan announces 370Z Japan Model is 340 HP, ver Nismo 355 HP.

We checked on the Bosch Dyno.

Allmost all the 370Z are 305 - 310 HP.

The best quality Header , Cat straight pipe and tail pipe combination gives the car around 350 HP.

With our ECU remapping, 360 HP.

After that, installing the 272 camshaft gives our car around 378 HP.

But I don't know your header nor tail pipe.

Your combination can give your car less HP than 378.


Any question appreciated.

PS We're now making VVEL components.
Our car can get 450 HP during this year.

Regards

Some of there numbers don't add up such as the claimed stock numbers and dyno numbers (pending type of dyno). But either way they claim a gain of 18whp after supporting mods and tune. Not bad at all if that's indeed the case. I'd pay that price for those gains

:iagree: especially once VVEL control comes out..

The VVEL components is what intrigues me most.

the claimed stock numbers might be different for Japanese market. Don't they have different gas/petrol octane ratings giving them more HP and no emissions.

18 whp is not bad, need to finds someone experienced to swap the cams.

they responded more on the VVEL, but as much as it sounds exciting, rather be skeptical about it. On the other hand, these are released by JUN, a respected and proven performance aftermarket tuner.



- Is this using ECU tuning or making mechanical changes to VVEL?

We already analyzed Nissan ECU VVEL mappings.

More than 450 Rear wheel HP, we have to make the VVEL intake camshaft from scratch.

Under 450 HP, mechanical VVEL modification is not required.

- Is this on stock car or with combination of headers, straight pipes or any other modifications?

As you see, the stock header , cat pipe and tail pipe is very bad for big HP.

If you change just EX camshafts, not so effective.

Atleast your emails from Circuit is more comprehensible and detailed than from the emails from Jun. :tup::rofl2:

I seriously did not undersatndnd any of this my cams are coming on the way so should I install them now or wait for the so called vvel thingy loool

Install them now and post up your gains! then look into the VVEL tuning.. I guess they are just starting to be able to crack it.

I read in the instruction manual that there are parts once touched or deassembled than they must be changed all together, and to install the cams those parts do need to be opened my question now is what should I do? R Nissan being to couscous about that
