It depends on the turbo as well. A stock turbo and GSC S2s have made more power in my experience than any other cam combo. We have tested FP4Rs, Cossie M2/M3, Greddy, Tomei (IX only), JUN (IX only), GSC, and Kelfords. On a stock turbo and pumpgas the GSC seems to be around 7-8whp higher than most others with a 28psi spike.

 

Didn't these do horribly on the cam shootout? Of course I think the test was on an EVO VIII.

 

Depends on where the "up top" is. I don't have any reason to rev my car past 7500-7600. If the S2's make 10-15hp at 8000 I'm not missing it and saved money not having to upgrade my valvetrain.

I'm not looking into making my car some high HP beast. I have a HP goal of around 400-425whp on E85. I don't see me having a problem reaching that goal with the S1's.

It will be low 400s but you should be in the neighborhood. The most I have seen on S1/E85/Stock Turbo was 400 even, though that car has a stock O2 housing (but every other mod?) which is obviously not very typical. S2 will be in the 420-435 range on a dynojet typically.

 

Yes, EVO VIII and a different cam altogether. FP's test car made 500+ (504 or 505 I think it was) with an FP Red and these cams on 26psi / 93 octane. The dyno was Cobb Tuning's Mustang AWD dyno in Plano TX.

I have the same cams in my IX now, although I haven't made any tuning adjustments since the install. The car idles so smooth I can't even tell it has cams in it. I could adjust Mivec to make it lope but I'd rather the car sound like a 300whp car.

 

Cool, I have 02, tbe, intake, licp, uicp, S1's, ebc, 1000cc injectors, and a Walbro.

I'm just looking for around 400whp. I like to keep things simple. Next mods will eventually be a ETS fmic and a FP red.

I was looking to run a FP red on 93 and my goal was around 400whp as well. I have several E85 pumps around me so I figured it was cheaper to buy injectors and a fuel pump and still get my HP goal.

 

You can make that goal with E85 probably with an upgraded turbo though. You could come close with the stock turbo if you turn up the wick.

 

Good info here...

So will cams on IX be beneficial if I decided to add a PTE 5857? Will not be maxing the turbo out since it will on a stock motor.

 

so gsc s1 cams are a good choice with stock turbo and not having to upgrade valve train? I simply am on sort of a budget, but I can afford to squeeze in a few things for the car. I am looking to get a good set of cams. But of course will keep the stock valve train and such. I was told hks 272's would be good for my set up and safe while delivering a noticeable gain after tuned. Any suggestions?

 

Answer, yes. I thought HKS 272's needed valvetrain upgrade but I could be wrong. Go with the GSC S1's. Perfect for the stock turbo, very nice gains.

 

I don't need a upgraded turbo to hit 400hp or more with E85.

You don't have to upgrade the valvetrain with the S1's. The car would have no problem being revved to 7800 with the S1's. Maybe a little higher, but I won't rev any higher than 7800.

I have a buddy with S1's and a FP Red. His car makes about 440whp on 93 and hits full bost at 3800 rpm. The car makes a great street car/daily driver.

HKS 264's, 272's, and 280's can be ran on the stock valvetrain. When I was looking for cams, GSC told me that the S1's are basically the biggest cams you can run on the stock valvetrain.

 

I probably have a different opinion compared to 95% of people on Evom...

I don't think you need to change your cams on your Evo 9. I make 540whp on the stock cams.

If you do a cost-benefit analysis on the parts.

You're looking at 500-600 for cams, 200 for springs, 500 for install.. A total of 1200-1300 prior to tuning.

If you send your turbo in and got an FP red upgrade for 1000.00 plus their install kit and injectors you're looking at a pretty similar 1400 dollars.

The difference is how much power you pick up!
I picked up 130whp by switching to the red
Most people are getting close to 30whp with their cams.

Bang for buck imo... Turbo upgrade.

I'll argue that the FP Red is a better upgrade based on actualy dyno number comparisons that I've done on a dynojet.

*************************

Now... I will be buying cams now that I've got the turbo because it will net the largest gain in horsepower per dollar now. I should pick up another 30-40whp from the cams for about 1100 dollars (Cams, springs, timing belt tool, head gasket, head studs)

 

That's a little on the high side for Cams. If you shop around, you can get them for a lot less and tuned for lot less then your total.
I picked up a used set of M2's for $300, installed for $250 and tuned for another $250 = $800 for about 30hp gain.

 

Be careful you don't get a set of the EHH8 batch... those are the ones that make like a toothpick and snap in two.

used 9 cams = high likely hood of being in that batch.

 

Over a year now, with zero problems. It all depends on who you buy them from (Well known speed shop). I've seen brand new Kelfords snap on this site, with in a few months.
