I am getting ready to do a complete engine rebuild/upgrade on my stock 6bolt. Along with a host of other stuff including 8.5 forged pistons, eagle rods, fmic+piping, performance springs, titanium retainers, and 1mm over valves, and eventually a FP3065 by next summer,I am going to be putting in camshafts as well. 272s need gears to set the degree on them, and gears are an added expense I don't wish to incur right now.

So, all things being equal, has anyone done a "side-by-side" dyno comparison between the FP2s and the HKS 272s?

p.s. I don't give a shit about any low rpm power loss.

I have the 272s and no cam gears. Who told you that you need cam gears with 272s?. Cam gears are used to fine tune cams(any cams)..

ok, so that does not answer my question. You do not need to degree hks cams but you need to if you want the most power out of them. FP's are supposedly designed to be "degreed" from the get-go.
my question was: has anyone done a "side-by-side" dyno comparison between the FP2s and the HKS 272s?

Look on page 4 of this thread. Lots of good info on the FP stuff.

www.roadraceengineering.com did a test with the HKS and some other cams including the Comp200's(FP2's). I've had both and the 272's win hands down, NO COMPARISON! David Buschur built my motor and said he has used the HKS for years and NEVER has had to degree them. Comp admitted degreeing was needed.
If I had a choice I would go with Crower stage 3's, the 414's. 5* more duration than the HKS on intake and 3* on exhaust along with a bit more lift. More power. If I ever change cams it will be for the Crowers, the only other cam Buschur would use. He built Sheppards last motors. He should know. mark

i was still trying to see which cams to buy and after this post i made up my mind

Is the test still listed on RRE's website? If so where abouts, I must be blind

I believe it's under Eclipse tech. I'll look and narrow it down. Mark

Maybe I am mistaken. A search on Comp 200's will have a link to it. It had the comp 200's ahead of the HKS by a bit. Specs are about identical, cam lobe design is different. Mark

I'd really like to see the comparisons too. I looked everywhere and couldn't find anything. Needless to say, I got a pair of FP2x cams. And the money I saved versus the HKS cams i was going to buy i got Manley springs and raised my rpm limit safely. There's more power in money management than many give credit.

EDIT: I see you replied before I could . Thanx for looking that up.

Try a search for "CAM alternatives for HKS" I got thru the first 3 pAGES BUT DID NOT FIND THE LINK SO START WITH PAGE 4. i KNOW IT'S AROUND HERE SOMEWHERE. tOO LATE FOR ME! MARK

I know this has been said over and over, but to reiterate, the FP2s are based on the 272s but with added power up top. I run the FP2s and my friend with 264s called BS as my idle was smooth as stock. It's unbelievable as I'd been told "big cams" meant idle issues and with no degreeing my car has no noticable "lope", still pulls 18" vacume at Idle and 5500RPM - revlimiter .. holy F----k

With no other mods I bested my ET by .5sec and 5mph on the first run.

Anyway, I dont' think you'd see a noticable difference btw the 272s and the FP2s except for the $200 savings, then again FP has other options (the "x" requiring dual springs and FP3) for specific applications for the same price.

BTW.. the Cam compare was on AMS's site but was limited to a 16G car on ~300WHP tune. The FP2s were not released at that point but the 272s made +25WHP. A larger turbo would have seen a more dramatic boost in power

I had the FP2's and never had 272 but I can say the FP2's were awesome. Perfect idle and crazy pull till 7500rpm vs. the stock cams.

Gave the final word to the soon to be fiance for my christmas present. Im going to go with the FP2Xs. Cant go wrong with forced performance IMO.

p.s. friday night im popping the question.

Congrats man, should be a great Christmas for you

Mark, AMS seems to have taken down the cam test link but there is a note that they are moving things around on their site. I'll post it if I find it, though have some of the graphs on my home PC


Found it: http://www.automotosports.com/cam_test.asp

, for what i paid for the ring, she should be getting me a everything on my list

anyone running the FP2x cams. I think im gonna order them after christmas

I wish I would have gotten those instead of the fp3's. The intake on the fp2x has more lift

The X series corrected a flaw in the design of the cams, the regular 1's,2's etc. haven't been fixed yet.

Thanks, WebTV limits what I can access but I could get to that one! I have the 272's but would go with Crower stage 3's if I wanted more power. 272's have 213* in/out. Stage 3's are 218*/216*, not sure on lift. An overlooked set are the Crane cams offering-224*/216* with .444/.424" lift. That seems to be the most aggressive as far as specs go. I did not like my Comp 200's(FP2's?) at all. I even sent them back to Comp for testing they were so bad in my car. Buschur built my motor and he said 272's drop right in, never has to degree them, Comp suggested degreeing. For what's it's worth.Mark

FP2s are fantastic cams, idle extremely well and you should see somewhere close to 3lbs pick up in airflow just by dropping them in and making your first pull on say a 50trim type turbo. HKS 272s are the most proven cams out there, you won't be disappointed. FP2x grinds have an accelerated ramp rate which should help spoolup the turbo when it comes into boost, they also have more lift than the FP2s. Crower stage IIIs have a little more lift than 272s but not quite as much as the FFWD L2 cams. The FFWD L2 cams were made to copy the crower stage III cams basically but they have slightly more lift and not all of the crazy duration. With FP2x grinds, L2 cams and perhaps even crower stage IIIs require upgraded valve springs. FP2x grinds idle like stock in my friends car, though he runs an AEM and can tune the cams to idle like stock. If someone has purchased the L2s and dropped them in I'd like to hear a review since they are rather new cams and I'm interested in what kinda power people are making with them.
