Besides the price point and options, can someone explain to me the major differences in regards to the engineering aspect of the cams between the two companies?
COLOR LEGEND
STOCK GREEN (HP)BLUE (TORQUE)
NISMO PURPLE
TOMEI RED
JWT YELLOW
JWT rules, now
i always thought that dip at 3000 for the Nismo and Tomei cams was quite suspicious. I am using those same Tomei cams and my curve is much more like the JWT curve.
JWT has great customer support from what I hear from my mechanic. They are very quick to help in decision making and offering advice and still do R&D rather than just throwing a product out on the market and calling it a day. Not knocking Tomei but the language barrier is there.
Since he makes no mention of it in the article Id be interested to know if bucket lifters were needed to be replaced with each cam swap. Measuring 32 buckets and rechecking with each cam is a critically important part of all this.
One could potentially need cams + 32 bucket lifters (@ $20/each) for a proper install. Not sure how this left out of the article.
LONG LIVE NA GLORY, and I do agree about Sasha. He is definitely the NA Maestro. Dude is friggin pioneer, for sure.

I have also heard that JWT has great customer service. A couple of local guys in my city use JWT parts and hadn't complain when they had any problems that needed to be dealt with by JWT. You're also right about language barrier. I remember reading some thread on here about how JWT goes into detail with harmonics and etc.
The cam profile is the reason for the dip. Funny how stock out performs tomei and nismo until 3400 rpm. I like Tomei. Got their headers but JWT for the cam shaft win.
Also, read something about aftermarket cam shafts snapping. Not sure wtf that's all about. Think the info was a bit old.

SNAPPING?! errr....wtf...that's sketchy/
Currently have ppe headers lol so waiting to pull the trigger on some cams. Stuck on the debate for the selection. C8s or tomei procams 272 with a 10.5 mm lift. Mid - high power range because LONG LIVE NA GLORY.
These are Tomei 262 cams..where is my dip? You can make an argument that the numbers are inflated due to Dynapak but that shouldnt change the curve itself.
From what I have seen, JWT makes a touch more midrange and a touch less topend than the equivalent Tomei cam.
Here is a pic from Tomei's website:
I don't see a dip anywhere. The first thing I thought when seeing the comparison dyno above was artificially poor tuning to make the JWT cams appear better than the rest.

"By using my personal 350Z race car for the test, we were able to remove almost all of the typical restrictions from the engine to highlight the changes that come about from a camshaft."
A quote above from the link above. To be more specific, I'd consider the modifications done to Sasha's as compared to another to determine how the cam's profile reacts per any given rpm. I suppose it's not the profile per se, but it's relation to all other modifications done to the engine.
It could be. I don't know of a reason to suspect Sasha was lying and getting a paycheck from JWT but anythings possible I suppose. If I were to fudge something like this, I think I'd make sure the stock cams looked as bad as the other 2 though cause it's tough to believe the stockers perform better than 2 out of 3 performance joints down low.

Neither do I but these dyno charts look like someone drew it up and just connected the dots.
Difference between JWT and Tomei Cams
