Has n e body who is running these cams dyno it and see what kinda gain they give?? Im just curious cuz i was thinking about getting them and i wanted 2 know what kinda gain u guys had with them.... TIA..

 

or if n e one has heard or read how much of a hp gain.....

 

just go stage 2...ITR cams are as good as 1's

 

Any cam out there with any following will give you good power with tuning, Jun, Toda, Skunk, Crower etc. I chose JUN, others choose different.

 

you sir are a liar!


i had itr cams in my GSR and now have the skunks stage 1. i have soo much more mid range and top end over my itr cam setup.

 

You don't know what you're talkin about.

Skunk2 Stage 1 cams are MUCH more agressive than ITR or CTR cams. Much more lift, duration and overlap degrees than OEM cams. Mid/Top end power surpasses ITR cams...

 

when running your ITR cams, did you keep the stock valvetrain/ecu? how about with your Skunk2 Stage1's?

 

I think you don't know what you're talking about if you think the stage 1 is "MUCH more aggressive than ITR or CTR cams." Yes, there is a noticeable difference between the two cams, but its not HUGE. Whats the lift on the skunk2 stage 1 cams? 11.58 mm. Whats the lift on the ITR cams? 11.5mm. 11.5-11.58=.08<-- difference in lift. 243 degrees (ctr) compared to 252 degrees (stage1) Yeah thats a gigantic difference The bigger difference is between the exhaust cams, but even then its still not that much greater. Both cams still fall into the "moderate" category.

I've seen one dyno chart of a tuned skunk2 stage 1 cam versus a tune itr cam set up. It made the same power until 5500 rpm, in which the skunk2 began to pull away with 5whp across the rest of the powerband from 5.5 to redline.

These stage 1 cams are great if you are staying with stock compression. But if you think its a "drop-in" cam, then you are wrong. All cams need tuning. A car with some tuned ITR cams will STOMP ALL OVER dropped in stage 1 cams. So you decide what you want to spend your money on. ITR or CTR cams + tuning $$$ = Price of brand new skunk2 stage 1 cams. If you have the money to tune the stage 1 cams, go for that. Anyways, its really up to you what you want to buy.

I don't think you'll see a 17 horsepower gain with just cams and staying with stock compression.

 

uh... ok. That was great. But why would anyone NOT tune their cams when they put it in? I'm pretty sure the Tuned ITR cam will be much better than UNtuned Skunk2 Cams, but if they are both tuned, the Skunk2's will yeild more gain, and it IS Noticeable. Much more pull in vtec.

 

TSK what kind of peak hp gain did the skunk 2 stage 1's give on that dyno u said u saw?

 

Courtesy to whoever's ITR this is

 

So as far as the stage 1's go compared to ITR cams. The stage 1's will net more hp, but cost more money. How much more money? Also, how do the stage 1's react with a slightly raised compression, say changing GSR stock to ITR or CTR pistons?
Also, how much more are the stage 2's to the stage 1's? Are the stage 2's ok street cams? or are they too agressive? how do they mate with the same raised compression?

 

ITR cams are $400.00 and Skunk2 cams are $700.00 - Skunk2 yeilds more power, especially with Cam gears and tuning. Definately better in the long run. Skunk2 Stage 1 cams are streetable and works fine with your stock valvetrain if you keep your redline to 8200rpm. Its also CARB legal.

Skunk2 Stage 2 cams are NOT streetable but yeild even more gain. You need to upgrade your valvetrain and TUNE the cams.

 

If you stay with stock compression, you will be very disappointed with your results for the stage 2 cams. Not that you're not going to gain anything, but your results will probably be simliar to stage 1 cams if not a little worse. I think the general rule for all-motor setups is "a little compression won't hurt " Definitely the stage 2 cams will benefit more from the higher compression then the stage 1 cams. Stage 1 and stage 2 cams are both the same price.

You will WANT to and it is HIGHLY suggested that you upgrade your valvetrain. If it were me, i would not put these cams in my car with stock GSR valvetrain. GSR valvesprings were made for GSR camshafts and nothing more. You are pushing your motor to the edge with these cams. Imagine driving on the stock valvesprings over a period of time. Think it might prematurely wear? If so it will bind and you'll bend/break some valves. In that case you're gonna have to pull your head off anyways. It is said that you can run ITR cams with GSR valvesprings if you don't raise the redline. Well the skunk2 stage 1's are little more aggressive then the ITR cams so you decide.

 

i completely agree with you.. might as well go itr cams if you plan to go stage 1's

 

What? Skunk2 Stage 2 cams ARE streetable. They have the same specs as the JUN 3 cams, and I have a few friends with daily-driven 190whp+ JUN 3'd motors.

With Stage 2s you will have to swap out valvetrain though, and a re-chipped ECU will be advantageous too. They are also made with the ITR-style intake manifold in mind as opposed to the dual,butterfly GS-R manifold.

Stage @ cams will go in my motor as soon as I can afford them and all of the other things that go with them like the aforementioned valvetrain and DYNO time to tune them in with my V-AFC too. I already run a re-chipped P28 set with a 9200RPM rev limit for which my B18C5 only sees max 9000RPMs for now.

 

Skunk2 Stage 2 cams are streetable. My car idles and runs like stock until the vtec kicks in. Now stage 3 is another story, those are not streetable.

 

[Echo]Yes Skunk2 Stage 3 cams aren't streetable.[/Echo]

Even *if* someone drives them on the street Skunk2 doesn't market them as streetable and the idle is supposed to be ultra-shitty. This applies to stage 3 cams y0!

Well the fact is my car does not idle crappy, therefore IMO it is streetable.

Here is a quote from the Skunk 2 site on the stage 2 cams...

"Stock idle and emissions characteristics may be slightly compromised, but fair-to-good driveability allows them to still be used on dual-purpose vehicles."

Again, I have had zero problems with the idle with these cams in my car.

 

This is my old chart when I first dropped in the cams. This was my first tuning session and now I'm at 196 whp, 135 tq. With exhaust disconnected I'm at 197, 140. Great cam, but needs lot's of tuning.

 

Second that! I've been running the stage 1's for about 8 mo. now, daily driven, I might add, and no problems - idles perfectly! Comparing them to ITR cams is unfair. I swapped out CTR cams for the stage 1's ond the difference is night and day. This, of course, is based solely from races I have "re-matched" (CTR cams, then w/ stage 1's) and the proverbial "butt-dyno". I HAVE NOT DYNO'D EITHER SETUP(for the record)! Before VTEC, I would venture to say that the performance is about equal(if I am not mistaken, the primary lobe geometry is very similar between the two cams), but an entirely new animal is unleashed once we go beyond 6k rpm! Take that for what it's worth! Just my $.02

with Stage 1, is it safe to stay with stock gsr valvetrain? if not would an upgrade to USDM ITR valvetrain be the thing to do?
what is a good affordable valvetrain that would serve as a safe system for a stage 1 cam with stock redline?

 

ITR outer intakes with portflow inners are your best/cheapest best. (about $160-$170 for complete valvespring set). And titanium retainers while you are at it!

 

Is it really necessary changing to Ti retainers when changing the valve train?
Which online shops allow you to buy inners seperately?
cheers

Like i said, with stage 1's, you really don't need to change out your valvetrain. Its perfectly fine with the stock Valvetrain as long as you dont raise your redline...
