Cams 12-15 horsepower?
I just goy of the phone with ben at JWT and he said 12-15 hp for the cams which i thought everyone was saying it was higher,and he said with VI ,cams and ECU he still wouldnt go over 7000rpm with the springs ? anybody have any ideas.

The HP figures for the cams sound about right, but for $1000 for the cams and another $1000 for the install, it sure doesn't sound like very much bang for the buck. You'd get a lot more out of supercharging.
The problem with the 7000 rpm limit is the valve springs. They either need to be replaced by stronger springs or shimmed to prevent valve float.

I would get them installed for $300.

I know there are no dyno numbers for JWT cams, but I would say its more than 10hp. After driving a car with JWT cams and a VI you don't even feel/hear the VI engage. That means the VI isn't making nearly the same power as the cams as a relative percentage.
The next consideration would be driveability. The JWT cams make the car lope and sound more like a domestic, and there is absolutely no power before 3500. Normal stoplight driving with an ACT usually bogs the engine a little, but once you hit cams its really nice JWT also has stronger valve springs so you can rev higher.

If you can feel the horsepower like that it has to be better than 10hp.
Also if i got these what rpm should i go to 7500rpm?

Still don't have your ECU huh? how long has it been? At least when you get it.. you can just swap ECUs.

He said "won't do ****", which I took as nothing. Which was wrong. But as a whole I agree with you 100%

I see LS1 guys with $2k heads/cams packages that don't gain more than one tenth in the 1/4 mile until they move the rev-limiter, then they see a half-second gain or more.

Would it be possible then to just buy the intake cams instead of all 4? Seeing how expensive they are and all.

The cams are $1100.

I'm not entirely convinced they would only give 10-15 hp either. I was thinking more along the lines of 15-25hp.
Anyhow their response that "going above 7000rpms is useless" is utter rubbish. Valvetrain is THE limiting factor to this. If you have cams with the correct specs and a valvetrain that can handle it, there is absolutely no reason this motor couldn't rev to 8000rpm. The stroke on the VQ is so short that piston speeds will remain low, even with it cranking at 8000rpm.
The MEVI alone lets power hang on til at least 7200, and I'd venture to say (though no one's been there in an N/A MEVI stock cammed car) that the MEVI alone could sustain power levels to about 7500rpm. With a set of cams that have specs such that they shift the powerband northward about 500rpm, an 8000rpm cammed and MEVI'd VQ would be a gem.
I've got a few emails to send to various companies with regards to this. If I find anything interesting I will let you guys know.

You could also use VQ35 retainers they are cheap as hell. See if you can just get the springs and then get the retainers from nissan and you can save yourself some $.
The JWT set is supposed to be $400 though, so $376 isn't a ton cheaper. Check with Mardigras on the Supra stuff and JWT on the Max stuff. Also before you go buying anything check with SGP Racing they have Tomei cams available in 256x10.2mm, 264x10.2mm, and 268x10.5mm.
It also says on SGPs website that the stock 2024 Al retainers are very weak. Not sure if this is true or if they are just trying to peddle their product, but it's something to think about. I wouldn't go rushing into a cam purchase just yet I think this is just the tip of the icerberg for the VQ because of the budding 350Z/G35 market.

Iwent to SGP racing site ,i noticed their all for the vq35de, are they completly interchangble with vq30de?Have you ever saw claimed power gains?
Well i never knew there were other choices ,maybe ill take it easy.

Anyhow I emailed SGP a little while ago and the guy there said to email him back in like 4-6 weeks because he was trying to get dyno graphs from Tomei. I'll email him again but I wouldn't expect a reply til Monday since it's a holiday.
