15-20 still a lot. Still a difference maker

But when a manufacturer advertises 15-20, i expect more like 15 tops. For 2.5k, it's tough to justify.

In the comments section of the CTD Gemrnay video, they say the 395hp is crank, not whp. Not sure if they just got their wording mixed up or what the deal is. Too little info though.

:shakes head:

someone needs to get these cams and put it on a real dyno, with before and after graphs...

lol, someone give me the cams and i will pay for the labor

No pics of the build, no dyno didn't happen... Read to much of this stuff to believe anything I hear and only half of what I see. ;)

2.5k is a exhaust that only gives you 10. I understand not everyone sends that much money on a exhaust. I just don't see why it's such a big deal.

Well, it seems to be a big enough deal that no one stateside has done it yet to give us a good third party dyno review.

Proportionate gains are pretty impressive without tuning. More info would be great, but any data is better than none.

Speaking of the lack of tuning: How the heck do you reset the VVEL as a distinctive process from completely resetting whole ECU? :confused:

i have to see a vid and before and after dyno. im just so skeptical with those crazy high numbers. just seems like too big of a jump


but...if this is legit, then this is huge

Elia ebyss, was anything done to the valvetrain during the instal, and are you on stock compression?

Yes you can run stock compression, I'm pretty sure some stated the cams were intended to be used in a 100% stock motor, and you will see 15-20 horsepower from just that mod alone. But I think you have to reset the vvel.

You will also have check the clearance between the cams and lifters to make sure they are in spec. If you don't best case is it didn't change, worse case there isn't enough clearance and you will melt something or run a valve into a piston, or if there is to much clearance it will slap around in there and either just break, or damage the cam from the pounding.

Edit: just so you know you need to do this any time you change cams, even if you put in another oe cam, it is best to do it whenever the head or block is decked as well in case the head gets distorted, basically any time you pull the head you should check it, it only takes 30 minutes.

Anyone know if the gains from the cams would be mostly high RPM peak or overall?

with more lift you will get an overall gain, with the duration increase it will shift the powerband up so i would expect it to move the power band up 500-1500rpm with small gains everywhere else. it is only exhaust and the timing comes in to play but I ould be surprised if it did something other than that. Also just to remind those who don't know it's all about restrictions so if through a bigger cam on a car with other restrictions you won't see the full benefit, as in if the cam flows 350hp but the exhaust only flows 300 you won't see it. same thing if the intake is choked.

Well if you guys want info you might want to look at cams on the 350z and what the gains the 350z had. Granted those have exhaust cams and intake but still. 3k price for 15-20 gain isn't bad. I would do this if I weren't saving for a GT-R so it would be pointless for me to do this cam install. If you have the cash stop waiting for other people to do something you obviously wanna do. What would be a regret? If you have a full bolt on Z then you'll obviously see gains. It's not rocket science. Like I said people spend this money on a simple exhaust with out complaining for what 5 to 10 hp? If I were keeping the z I'd take my car to Switzer performance in Ohio that are known for the GT-R work and get this done. Vendor Garageline have a set for sale for 700 shipped so you don't have to wait to get shipped in from japan. A lot of interested people about these cams now someone get some balls like OP. Don't bitch at OP for not having more info. He did what a lot of us want to do and said they work.

Lots of lost money, time, possibly performance, and a possible blown motor? :tup:

700 is a steal. Bruce, buy it :)

Not trying to hijack the thread but what are your thoughts on the JUN auto throttle bodies? I believe they are enlarged 2mm for optimal performance and reliability...??

no one is bitching at the op for not having more info, we're glad he has the info that he does. There's just not enough info in general for many to go for it ta this point.

Oh Ethan that sounds like more of the worries of a turbo build to me. It's a cam install it's not hard but it's not easy either. It is what it is. If you only make 10 hp. Still see no reason to regret it. Lost money? I mean more money can be made it's replaceable if you have a career. If your worried about wasting money you shouldn't be modding a 370z period anyways. Don't get me wrong I understand where you are coming from buddy let's watch the nba finals tom:tiphat:

go Spurs

I did spend a lot of money for my install but I don't regret installing the cams at all even though I need more tuning time. I love the build. I know it's not a lot of power that most people expect but it's still a great addition to my car and it's very reliable. GTM built my heads and installed there durable parts.

Your build is great, it's just got so much in it that we can't figure out what is attributed to what in terms of improvements.

I'll be watching the cards and royals final game tomorrow. gotta watch kc take this series! :happydance:


sooo op... dyno graph? video? anything?

Op said it would cost him $70 in Kuwait to get the dyno graph so that's a no go. He gave his final numbers, but we don't know his baseline, though it was contextually suggested that he was at 348whp before the cams.

wonder why tomei wont do the cams for vq37..

Tomei dont do anything for the vq37

Sent from my SGH-T999L using Tapatalk

yeh its a pity, they made good cams for vq35 and had good reference info and all.

surely there should be a lot to gain with aggressive exhaust cams and properly tuned vvel?

not sure how wide vvel's range is but it seems like it can increase the lift to a point where the valves it will actually hit the piston, and wide range of duration control. its like god given cam shaft.. if it can be tuned easily..!

20whp from jun cam sounds very good already but they dont seem to share the reference dyno and etc!

From the questions I have asked some companies about cams was they were waiting for VVEL to be tunable but on the same side tuning VVEL was not a strong push because no cams were out to maximize results.

I know uprev has opened up VVEL tuning in its pro level software package and ECUtek is suppose to have it.

Who did the tune for you ? Bader Norris ? ;)
5w30 redline oil ? was that the same oil you put in when you first started the engine after the cams installed ?

anyways, for those who worried about pistons/valves contact, i would recommend CP pistons for you ;)

How's the car running after tunning? Do you have any videos?

I just don't understand why it is so difficult to post results from this upgrade. It must be super classified information.

From what I have read, these cams were OK to be used with the stock tune. Doesn't seem like there would be gains at all. I'm not surprised that we haven't seen results.

they definitley changed my upper rpm performance, car builds power to 8200rpm now.

Which oil pump you running? And where is your redline set at?

Its pfs pump redline is 8200

Wait u have these cams?? Lol

Yup the 282's

Nice!!!...do you mind of ask you what other parts did u buy? And how how were your gains?
