Just ordered comp cams

[DSMJim]

Thanks for those links, this is kinda what I figured though it's nice to see it writen out. Thats pretty standard and I'll have no problem doing it like that.

 

[Tallen]

So who has them the cheapest. Only vendors I know of are Slowboy and Summit.

 

[anconover]

theyres a guy on ebay thats sellin em for like 435$ shipped i think it was. I think i typed in 4g63 cams or somethin.

I have a set for sale 100200 Already broken in $390 shipped. The 11 second pass ate my center diff, so I am parting my DSM out :-(

All over a little diff? If you think thats a pita try replacing a broken output shaft, which broke because I upgraded my center diff that broke

I have nothing to compare against because I did this all at once, but I have the 101200's just dropped in NOT degreed on a 2.4L and a 67mm turbo with a close to stock head (mild clean up port job). I don't know if it's the cams that are not as good as I expected, but power drops off up top pretty bad so I will try to degree them sometime and redyno it. There's too many factors including my head that could cause the drop off in power but here's what I got for some kind of "results" with the cams. So far, other local 2.4's with the HKS 272s power doesn't drop off as drastically as mine does.... so as for now I am :thumbdown about the Comps directly dropping in a 2.4 or any motor for that matter.

After read all comments, i have same doubt...
Are "race COMP cams" the same than "HKS 272`s"????
Thanks for solve my question

 

[anconover]

Comp 101200's are not the same as HKS 272's. They have a much higher lift, the difference is quite large. The comp 101200's have more of a low end loss compared to the 272's, but offered alot more top end over the 272's and actually dropped off later than the 272's per graphs posted in the forced performance cams thread.

The 101300's and 101400's are a better choice for a 2.4L probly.

 

[eclipse98gs-t]

Thanks for that post!
Do you know what is the better range to get the maximun potential of a "race COMP cams"???
What about the idle with those cams?

DSMRULES

 

[eclipse98gs-t]

Anyone?

 

[anconover]

Go look at the graph i mentioned before. And the idle is suppose to be quite good with the comps.

 

[TurboSpoolinIns]

Anyone?

I didn't really get what you were asking but as you can see my chart with the Comp 101200s vs the HKSs, the HKSs came out on top.

Here's the chart with the 272s in with NO other changes except maybe a psi of boost. At 30 psi, the car easily made 50 more whp than the Comps did. I didn't want to post a HKS vs. Comp post or anything before, but I feel I should just because on my personal car it did make a difference of 50 whp- the HKSs making more power. The charts that are on the previous page are the FP-Comp cams which I guess are degreed to be direct drop ins so I don't think that's really a straight up comparison for HKS vs. Comp because to me, it's more like HKS vs. FP-Comp cams. The FP cams may make more and be better but with just the plain Comps as drop ins, the HKS were better. I don't know if that all made sense as I'm kind of rambling, but yea. Here was the chart of the 272s on 1 more psi of boost. I can dig up the charts directly comparing the 272s and 101200s on the exact amount of boost and post those some other time. There is still a 50 whp gap with HKSs making more.


I guess it is posted up on this page already, but I'll just post it up again so those that want to compare can do so without scrolling up and down. I'll just edit the top post and delete that picture up there.

theyre is also a post of comp 101200's destroying HKS 272's in top end. Hard to tell without more real testing.

I don't about that Alex. On TurboSpoolinIns's setup, THAT was the only change on the same car. I think I will stick with the 272's. I'm glad I got myself a set.

 

[anconover]

I dunno. The only way i could see the 272's putting out 50whp more is if he lost a decent amount of power from the addition of the comp cams. I dont think ive seen someone gain 50whp from a cam upgrade, let alone an addition 50whp over another upgraded cam.

Also notice those dyno runs were made a month apart, who knows what can or did change?

The runs were made a month apart but I swear there was no changes except the 272s. Even having the runs a month apart, I don't think it'd make the 50 whp difference. I could see 10-20 whp from different day conditions, but it showed the HKSs clearly just made more either way. BUT, the reason behind the cam swap was that my comps started flaking chunks off the lobes (the lobes flaked and were found in my oil pan- CHECK yours-maybe I was the only one who got a bad set) but I'm sure I dyno'd when the lobes were all there because it was only within a first few hundred miles of having them in. I found some flakes in my oil pan when I accidentally stripped my oil drain and had to pull the oil pan. That was 1800 miles after they were installed, I dyno'd within a couple hundred of them being in there. If you want pics of the lobes, I can provide them. Comp took care of me very well so for Comp customer service. That was the only reason I put the HKS 272s in and dyno'd with them because I was curious to see what it'd do. I do know the runs were a month apart BUT that was the only change I did. It was all dyno'd on the same gas (C16) and was started at lower boost (27ish psi). The first few runs netted the same power levels that the Comps did at 30 psi (~550 whp). Then we upped the boost to 30 and it made 60x.xx whp. Then we ran it at 31.5 psi and made the 617 whp as it was running out of fuel pump (255 lph non-high pressure ) so we quit there. Trust me, I was surprised too and very very happy to hit the 600 whp mark, but I didn't do anything with the car, no boost leak fixes, nothing. People who know me know I didn't touch the car after it started because I was just that lazy after putting the car altogether. I was just happy it ran. I guess maybe the Comps just really need to be degreed if that's the case because the 50 whp is legit in my case. It might just be like the MR2's that need their HKS 272s degreed. We had to degree a set of HKS's and added a bit more timing on an MR2 and it did net another 50+ whp. The MR2 had a hard time making under 300 whp before degreeing it, and after it made 340-350 easily.

Probably FP's would loss less, or probably FP3's...don't know...I would like to see FP3's vs 272's on a 2.0l ...they say they idle like stock even on a 2.0
