CAM alternatives to HKS?

[bigjangin]

yes Im interested too, the cams seem very promising but I havent heard of a single person that has used or tested them.

I have experience with both of the off the self Comp grinds. See my profile for the setup used with each.

The smaller Comps (#101100) are far better for the street. My lowend and off boost response was slightly increased over stock. I saw 22psi around 3600 rpm. The idle is undetectible and sounds exactly like stock. I saw a max of 42.8 lbs/min at 24psi on my setup with the smaller cams.

I swapped them out for the larger Comps (#101200) a few weeks ago. I had to say goodbye to ANY lowend off boost response the car once had. Not much happens below 3500 rpm. Spool up time increased about 400rpm giving me 22psi about 4000 rpm. The top end rush is absolutely insane and well worth the lowend absence IMO. The idle lopes a bit, just enough to let you know something is going on under the hood. I saw a gain of 3 lbs/min over the smaller Comps at 24psi seeing a bit over 45 lbs/min. I'm waiting on a Magnus intake to take this to the dyno. The numbers will tell all.

In the end I am impressed with the quality of the Comps. I had no hesitation going with Comp as I have used at least half a dozen in Chevys and Fords with great success.

Another plus for the 2g guys, is the CAS is pre drilled on the intake cam. No drilling and tapping necessary. For the price, the Comps can't be beat.

*edit* I had the wrong part #s

what was your spool time with the stock cams? With my 50 trim and stock cams I hit full boost at about 3900 rpms. The cams were fine to drop in and didnt require adj cam gears?

 

[anconover]

also, what are you revving to now with the more aggressive cams? and are you on stock springs/retainers? Looking at the lift of the more aggressive, made me kinda weary to think to try them on stock valvetrain and rev past 7k

I was running the stock cams with the stock 2g head, so the spoolup comparison isn't ideal. I would get 20 psi at 3500 on the stock topend. This was with the DNP header though. The header improved it about 200 rpm.

I have them installed straight up with the stock cam gears.

Where can you purchase these cams? I looked at Forced Performance and Turbo Trix but neither carry them

 

[anconover]

slowboyracing.com or i believe summitracing.com has them cheapest.

The cams might not be on their website but give them a call or email them. Either shop can get the cams quickly if they are not on the shelf now.

As of now, I'm sold on the Comp cams. Which set I'll get will depend on what turbo I have when I'm ready for them.

Also, I see on SBR's site that Crower has their own 264/272 setup that "replaces" the same HKS setup. If they really are replacements for the HKS's, shouldn't they be able to be "direct-drop-in" like the HKS's are? Any other comments on this setup?

On that same note, can the two sets of Comp cams be mixed to the same effect. Ex: 101100 intake cam and 101200 exhaust cam? Can it be done or do you recommend it?

Thanks,
Jake

Yes you can get the "split pattern" grind. The 101100 set comes with the 101-101-8I intake and the 101-102-8E exhaust. The 101200 set comes with the 101-201-8I intake and the 101-202-8E exhaust. So just ask for the 101-101-8I and the 101-202-8E camshafts.
I am not 100% sure if this combination is the best but I did a similar thing to my car and it ran great. But, I never put the smaller exhaust on or tested the exhaust manifold pressure so it might not have been optimal.

some big cam seller is selling them on ebay for buy it now at 440 for both comp grinds

 

[WhipmastaFlex]

webcams streetgrind. i didn't have to "dial 'em in". check out the dyno sheet for results, especially between 5k-6k rpm (before i hit fuel cut)... see sig for details.

oh... and as for them 'dog-ear'ing, they don't make regrinds anymore. here's a pic after 20k+ miles

can u put that chart into english, was having trouble understanding it.

 

[WhipmastaFlex]

266whp @ 10psi on 14b. goes insanely lean due to stock fuel set-up and fuel cut. still picked up assloads of power after 5k.

 

[btrux06]

is the blue before and red after install?

 

[WhipmastaFlex]

red is 3rd gear, first pull. blue is 4th gear, second pull, nice and hot :thumbdown

I'm going with crane cams. My friend has their street grind (0010) cams and they were a direct drop in, no changes to head at all, and it pulls hard from about 3k all the way to readline. No degree wheels, just dropped in straight up. Very nice IMHO and a great alternative to HKS. Me, I'm going with cranes stage 3 cam (0014) accompanied with ferrera dual springs and retainers.

hey anoldsman....if i were going to do the spilt comp cam grinds would you recommend upgraded valve springs. I was also wondering what the idling characteristics would be. Im in the process of a whole engine overhaul and was interested in going with the comps seeing the good feedback in this thread.

 

[JASON ROSARIO]

I also wanted to know if you have more compression if that would help make the car idle better. Im talking about 9:0:1. Thanks

The stock springs work well if they are not worn out. If you are uncertain of the "life" of your springs I highly recommend replacing them with aftermarket springs and retainers. The biggest improvement is from the reduction in weight by using the aftermarket titanium retainers and the added spring rate only helps.

I do not believe that it will help your idle much. However, you can widen the lobe separation with more compression without loosing low end. This will help your idle. You will have to experiment with the cam timing to see what suites your personal preferences the best.

Good info, I think I'll go with the Comp mix and match set as well. Good prices. Hopefully with FWD I can see 30+HP gain.

 

[my_gst95]

Just the post I was looking for. I'm thinking of ordering a pair of Comp Cams from Mike Huml, but was wondering how 'drop-in' they would be? I like the fact that HKS's are plug-n-play, no need to degree anything. Are the more aggressive, race cams from Comp just as plug-n-play? I'm also hoping to maximize my performance with the E16g I have. Since i don't care too much for low end, daily driving abilites and just want the most power I can get in a straight line, I'm assuming the agressive pair would be best if not a mix with the street exhaust cam. Suggestions? Also does anyone have a video/audio clip with the cams installed and tuned?

I have the aforementioned cams. I cant really give you much of a difinitive answer on them though as I have not been to the dyno yet. All I can say is it feels less powerful down low, but is considerably more powerful above 4000rpm. Also, I make 15psi at about 2800rpm.

I just saw a set of Comp Cams (250/251) that one of my customers bought (elsewhere)… They are clearly re-grind and to make matters worse, they started out with cams which were SCORED!!!

COMP does not regrind the factory cams. We have always used new cam cores. Your customer was clearly lied to or is lying to you.
