JUN camshafts

[LandSpeed-DSM]

boostin tested them on a evo9

"Here's a comparison between a set of Jun 272 Evo 9 Cams and a set of GSC S3 Evo 9 Cams. The boost level is the same (40 psi). The only change in this test were the cams."

I don't have MIVEC nor an Evo, but I will say the GSC S3s compromise very little for such a "big cam" in my 1G.

Correct me if I'm wrong, don't some the Jun cams need to have the lash pivot changed into a solid pivot ?

So is the jun can a plug and play set up, or do you need to change springs and so forth, what does the jun cam compare to the others delta, hks and others regardless of price.

Also curious. I know a few have suggested valve springs.

Delta regrinds are a joke...

The Jun series of camshaft are held to the highest quality during grinding and the profiles that they use are awesome. The JUN 272 is the most aggressive 272 I have found. More aggressive than GSC and Kelford. I know that GSC based there 272 grind off of the JUN 272 but I do not believe it is an exact match.. My evo is getting a set and if they weren't so expensive I would push them harder.

The 264s would be a great combo for ya. Small duration and a mean lift.

I think Jun 272 cams are more aggressive than GSC2's but I'm not to sure about the Kelfords 272's. We may know soon.


I think Jun is one of the 18 cams Dsport recently tested. But here is some info I posted not to long ago about cams.
Yeah it is on a different model car. But most of the cams have the same duration and lift

.

And Jun 264 for $400 is a good deal.

 

[Kyle_T]

Jun 264 or kelford 264? Which ones for evo 3 16g? Both are about the same price.

 

[92AWDHX40]

Found my choice.

 

[DSM_GSX01]

Just ordered my GSC S2 cams from stm. Good deals going on. Got GSC spring kit also.

 

[92AWDHX40]

I read the ds sport review too it just came to the house nice reading.

the jun 264 is a nice cam. years ago had a set running on a 2.3 with a 20g. it was un awesome setup. they are more aggressive than hks 272. lopey idle even on the 2.3. ran with crower single spring set. that being said cams are extremely setup specific. compression, head porting, inake and exhaust manifolds, turbo size all have a say on how a cam is going to work in your setup. so looking at cam tests are useless unless your setup is the same as what was tested.

have a 2.3 with 20g a few years back. running fp2. all the rage gsc at the time bought their s2( 280cam) and hated them. pulled them right back out. they killed low end torque. fp2 was far more fun. currently run the fp2 with 2.3 and hta green and still love them.

You statement about a cam test is correct to a point. There are many variables to a setup and cams are somewhat setup specific. So how do you differentiate what to choose? You can do so by knowing the real duration and lift. That sets a standard across the board and makes it easier for comparisons. Like jun 264 the kelford 264 cams are also way more aggressive then hks 272. But no one talks about HKS 280's anymore . Where do they fit in? With that being said from the cam analyzer info I've seen DKS 3's (HKS 280 regrinds) are very close to and in the same category as FP 4R, Kelford 264, and jun 264.

Well do you think the jun 264 would be too aggressive for an evo3 16g? Its still a 264 cam. I dont want something that will idle like garbage and have no streetability. I want something to idle close to stock and be very responsive. I will also be getting adjustable cam gears to dial them in.

The fact it says 264 doesn't mean anything and viperlp01 is correct. Jun past or present has always been more aggressive than most other cams of the same number. That Boostin Jun 272 vs GSC3 dyno shows that and also GSC shows similar dyno results on their site from a dsm
http://www.power-division.com/product.php?productid=16186&cat=297&page=1

but Imagine what a Jun 280 vs GSC3 looks like .


You stated you wanted to retain as much off boost response, and midrange power and torque as you could. I feel none of the cams I listed in my previous post are to aggressive for a your needs. But going off Jun 272 history. I am going to say Jun 264 may be the most aggressive of those cams but not overly aggressive for your needs. I'm say performance wise It's just under GSC2 and Kelford 272's but what is the purpose of the car? is it just a street car or are you racing it on circuit track?

 

[Kyle_T]

Street car. Evo 3 16g on pump. I want it to idle close to stock, spool quickly and keep as much torque and off boost power as i can. I have ecmlink v3 to dial in everything also planned on getting adjustable cam gears

 

[92AWDHX40]

Well street car, i would find some cams that are good with idling if you dont want to change things out, in the future but if your like me i plan on using my spare head for upgrade from what i have now, knowing my car will be a street and track car eventually. Having link does help, i like the thread by kel on cams, hes been very helpful.

16g works best with a smaller cam. the hks 264 did well in the cam test. I would say FP1 would work great. I think the jun 264 will be too aggressive

Basically you just want a step above stock with a lil more punch. Well then all you need is Fp 4r. They seem to be closes lowend power wise to HKS 272 but they are more aggressive with better topend power. The best street cam to a lot of people I know. But Fp does not sell them anymore. So I have to say the closes cam to that is DKS 3.


here is a info on 272/264 DKS to 272/272 DKS. The DKS 3 will compliment the fast spool of the 16g with minimal lowend loss.

[Kyle_T]

I thought 272s sort of lack low end compared to stock.

 

[92AWDHX40]

Fp doesn't make the fp4 anymore I thought they were out of stock on one of the vendors when I was looking at cams earlie.

 

[spoolin ddub]

not HKS 272 etc. with these cams you won't really have any issue with bottom end loss. HKs 272/DKS 2, and BC 272 which are a small step above stock.
Then you have the next step of cams which will give a very very small loss of lowend compared to stock. smallest of them BC 280, then HKS 280/DKS 3, then FP4R, then the largest of them so far being kelford 264. I'm not certain where GSC1 fits because I have not seen any real cam numbers on them. I also haven't even seen the complete DSport cam test article but hopefully it will have enough variety of cams to help out.

Fp doesn't make the fp4 anymore I thought they were out of stock on one of the vendors when I was looking at cams earlie.

Nope. Fp about to stop selling cams all together. And they barely have any DSM specific parts at all. Look on their site . You'll see no DSM or Evo 9 cams!

Hey man thanks for the update, its near spring and I have a lot of things to get done in 2014, cams are on my list. Hope fully before sd tuning.

 

[Kyle_T]

Haha man, now I dont know. So many choices, so many variables. How about hks 264/272. Seems popular, mild cam. How responsive will it be with the 272 exhaust cam?

I'm about to send you a PM

 

[RipperXX]

Based on what the original poster said he wanted. I would say GSC S1, only because the tests I have seen with them, vs stock cams, they gained pretty much everywhere without losing any low end torque, they don't have insane ramp rates either so, so long as your not raising the rev limit you could get by with stock springs (though I would at least go to OEM Evo springs).

That said, obviously you wont notice the same kind of HP gains as you would on the more aggressive cams suggested.

Youtube GSC S1 4g63 and lesson to the idle, pretty nice sounding idle to me, just a little lope but running pretty smooth.

 

[Seamus]

I know they aren't popular here because they aren't very aggressive, but I like my bc 272's. they work really well with these small bolt on turbos like 16g and 20g and they idle basically stock with good vacuum.
