JUN camshafts

[Kyle_T]

I think Ive narrowed it down to HKS 264/264, HKS 264/272 or GSC S1. Whichever ones I can find a better deal on.

Crower 272s arent a bad buy. Comparable in price to the others you just listed. My personal experience was not too much loss in the low end. Conversely(and this may be due to my 63ar pte housing) i choke up up top. I get nothing really past 7500. Mine are not adjusted though.
I hope you are getting cam gears with whatever cams you get. From my reading i have learned this is so incredibly important in dialing in the car. One of the most effective things you can do is degree the cams.

 

[Kyle_T]

Yes I will be getting adjustable cam gears

 

[lil corb]

I agree that gears will always bring the most out of any cam including stock from I gathered hks 272, comp 102100 (fp2) and some other basic non aggressor cams are the best to look into if you aren't looking to get gears. Obviously you won't get the most power compared to more aggressive cams

FWIW we had comp 101200 in Tylers 16g car. It was running solid 10.7s at the track on the stock bottom end and our ZFG head combo. We knew the cam was holding us back so we decided to go after the crane 264/258 which is a huge cam in comparison to a comp 101200(FP2s). The car ended up running 10.4s with just the cam change. We did not have the dyno then but honestly that is a pretty big indication as to what can be gained when the right cam is picked. Don't be scared of a aggressive cam on a small turbo setup.

I will also add with some technical data to clear up all this "272"

The advertised duration("272, 264, 274, ect") is measured at .001 of lift or 1mm(.004). That number should only be used to get an idea of how aggressive the ramp is. The amount of airflow at that low of lift is damn near completely pointless to even choose a camshaft based solely off that number

Lets look at some things

Comp101200s-
Advertised @ .004- 259/258
@ .050 numbers - 212/212
Lift-.411/.398

HKS272s- Baby 272s. Thats why no one has issues with stock springs.
advertised "272s"
@ .050 numbers-195 / 195
lift-.399"/.379"

Crane 264s- You can see how aggressive these cams are. Nice split between the intake and exhaust. Small advertised for a clean idle with a serious @ .050 number and lift.
advertised- 264/258
@ .050 numbers-224/216
lift-.443/.424

Kelford 272s- larger advertise, slightly rougher idle, still a decent @ .050 number, modern camshaft profile.
Advertised- 272/272
@ .050 numers(actually at .040 numbers)-226/226(est @ .050 is 220/220)
Lift-.443/.443

You understand were I'm coming from with the real duration vs the advertised numbers. That's why im interested in the dsport cam test. 18 cams all tested that show the advertised numbers and the real numbers.

like the keldford 272 here. but these are the real durations, and its no where near the advertised duration @.040 226/226 or the est @.050 220/220.

The FFWD DKS 2 is just a HKS 272 regrind. HKS cam card numbers are based off 1mm and FFWD only gives the real duration @ .050 and lift. So I look at the numbers off their site from a cam analyzer.
http://www.ffwdconnection.com/dsm/dks2.html

18 cams gives a lot of data to choose from !! And its needed because none of the cam companies us the same standards and the numbers may be off by different ratios. No guessing. Just unbiased numbers across the board. So I would recommend waiting to see the results to get the accurate info. If you can wait.

hey viper, those crane cams sound interesting. as i am running the 101200 now on mt 2.3/htagreen . i know the cams are holding this setup back quite a bit. How is the idle compared to the comps 200? was the extra 3 tenths after some more tuning and tweaking? do you remember if it lost low end drivability?

 

[viperlp01]

Without a dyno it is hard to overlay actual torque lost down low if there was any. The tune might have changed a little bit due to the added power but I know we did not go crazy with the tune. Tyler is still running these cams and the thing has a pretty easy to tune idle with 2150s on meth.

 

[spoolin ddub]

Got the final dsport cam test issue. It is hard to break down what cam is more suited for a setup but this test has most of the variables covered. A very good read that tells more then just peak HP. So I suggest you go out and get the mag.

Just read the d sport review on cams good stuff there too.

Part 1 or part 2?

 

[boost97gst]

For the evo guys the Tomei was the winner. Ive never even heard of the brand smh, Shows how much i know. These are for MIVECs right? I suppose the info would still be valuable to us though, either way.

Found Tomei 270,280, or 290 cams for ~$470 shipped. Could this be right?
I wish crowers were in the review...

 

[Pipnorcali]

Tomei has been around since the 60's legendary japansese tunning shop

 

[92AWDHX40]

I read part two.

Not sure how much they cost for DSM but AWD Motorsport has them for Evo $459. Kind of messed up the generational gap there is on performance parts. I recall on one of the earlier post a guy never even heard of Jun. The Tomei cams for DSM's have the same specs as the Evo cams. And just because it made the most peak WHP doesn't necessarily make it the winner.

Been considering fp2/comp 101200 for my setup

 

[spoolin ddub]

Been considering fp2/comp 101200 for my setup

those seem like a good match. the next cam after that is BC 272 and then the next cam after BC272 is HKS 280/DKS 3. Both are between comp 264 and comp 272.

 

[Kyle_T]

Yea I haven't been able to find a whole lot of info with fp2's and 16g's but it seems like they idle close to stock and retain most low end but open up the top end a good amount. Would like to see some torque curves with these cams

here go some FP2 16g dyno's.

it comes down to your goals for your car and budget as you can see there are few cams out there but your going to have to just pick what works best for you, of course there are those who have run this cam and that cam and this and that review but youll know for sure once its on your car and your present mods.

Looking at it now I'm throw in Comp 101100 with HKS 272 and BC 272. They would give you almost No low end power loss. If you feel you can sacrifice a very very small amount of lowend with more push up top then look at Comp 101200, HKS 280 etc. As for the JUN 264's. Although they are a nice ass cam and you found a set for a good ass price. The fact is they just may be a little to big for your goals.

I have used both fp1 and fp2 with a 16g same setup. there is a torque loss with the fp2. if there are people claiming no torque loss with bigger cams I would say they are not very observant.

 

[Kyle_T]

Hks 264/272 vs. fp2(comp 102100)

Thoughts? How much torque/low end will I loose with the fp2's? How much top end will I gain with the fp2's? I have the evo3 intake mani, fp exhaust mani and the evo3 turbine housing is ported.

 

[lil corb]

With my evo 16g with fp manifold and fp2 I see full spool by 4200 in 3rd gear at 22psi. I am sacrificing a little spool up time but top ends wants to keep pulling past 7500 after fuel cut. Turbo doesn't taper off either. That sacrifice is worth the top end pull IMHO. If you're into auto crossing though might not be the best set up

 

[boost97gst]

You sound very very concerned about low end. If mine were a DD, i would be as well.
Have you ever considered just, i dont know, a stock set of cams? Maybe some adj gears to go with it, some dyno time and you could get a little more out of them without losing that low end/off boost that you are worried about.

Also, you could get a decent sized cam and if you plan a build simply go with high compression pistons. That is a more costly answer but you will see much better off boost performance even with a mild set of cams.

Im not that experienced with different configs of turbos and cams. I dont know you're level of experience. But i think low end grunt is not gonna be a worry with a small turbo like a 16g even with most 272s. Thats a small, very fast response turbo. 4 pages of this........ but i like your approach, gather every bit of info possibly before buying. I hope you are happy with whatever you choose to get, eventually
