1G-specific Forced Performance Cams

i've searched but not finding anything over here. and there was a thread on it on dsmtalk. but oh well. can't get to that. anyway, my next mod is probably gonna be cams. looking at the FPcam2's. i think i heard that they give better topend than the hks 272's. and that they also are able to go in pretty straight like the 272's without necessarily needing cam gears.

anyone have any feedback on these things? also, is it possible to know any kinda horsepower gains from slapping these in? at what point would i need aftermarket springs in there as well? is it if i'm revving over a certain rpm? or over a certain lift? would like to maybe go ahead and throw the cams in now and springs later if it's possible to get by without them for now. planning on having the head ported out pretty good later on but would like to run the cams as is for now. and of course, choosing cams over a sheetmetal intake would be the better choice for now, right? thanks for any info.

The FP cams seem to becoming slowly popular. Im not sure the lift on these, but most comp cams (fp has comp make them to theyre spec) require springs/retainers because they have a very high lift. At least comp highly recommends them. Usually your pretty safe unless revving past redline, but not with a higher lift cam. The cams over intake manifold is a smart decision.

I have a set of comp 100's and these are close to the FP ones and I LOVE THEM. gained ~15awhp on pump gas and ~35awhp on race gas over stock cams.

im not sure how closely they really are related, i thought someone got the specs, may have been on dsmtalk tho. Youll def see a well worth it gain from cams with your setup. 1 way to find out, dyno now, get some, dyno again =p

Less lift than a 272 according to some guy on dsmtalk (rip) with his dsmlink.

15 horsepower just doesn't sound like it'd be that big a difference to notice. heck, i see underdrive pulley advertisments all the time that say 10-15 horsepower for turbo'd cars. and it doesn't seem like that big of an increase. could i maybe get a bigger gain considering the size turbo i have maybe??? we need a cam comparison test like they did with the intake manifolds....

well, it is off topic but i'll post real quick....then back to my thread. no hijacking my thread. some say it's bad. some don't. probably good if you have a balanced motor of course. on my second one now of course with no problems and i haven't known anyone with one that's had a problem. could be a matter of opinion. i'm just doing the crank though. other pulley's could be too much and i've heard of some people losing battery power etc. but do some searching. this is a well discussed topic i know. anyway, back to my thread now thank you!!!

Aftermarket pulleys are fine everyplace else but the crank. No super fast guys run them, and there is a reason. They mess up the cranks. I'm passing a kidney stone right now or I'd get you a good explanation of why, but take it from someone who has seen damage first hand, along with many tales of it online, pulleys suck y0!

I called and asked about their cams. He said they have spent the last couple of year developing them. They are susposed to have a better top end and a better idle then the HKS's. I am looking at getting the 272's (fp2's) real soon

Did they say that they needed cam gears or upgraded springs/retainers ??

its a well known fact that when you go with a larger cam you NEED springs and retainers. i didnt know that at one point in time and umm well needless to say i buy cower products now.

well 272's added 25hp to a b16g in the old AMS test no? So you pickup some decent power. And the FP cams were suppose to be pretty drop on like the HKS, and i recommend springs/retainers with them.

im not share bad information.. ask every wiseman on tuners here.. you need higher tension valve springs when you use higher lift cams.. and when you done use them a majority of the time the valve will float cause you more issues than i choose to type about..

you can drop in a set of hks cams with no real problems.. but with a comp cam or fprced performance cam you need to put a set of springs in.. and how many people do u know? better yet spend you hard earned money put a set of cams into your nearly stock dsm and see what happens..

if you want to continue this you can get ahold of me via aim or pm me. keep it off the boards

Weather or not you need heavier springs has nothing to do with the manufacturer of the cam, it has to do with lift and duration. Example: The stock cams have .366" in / .343" ex lift. They suggest better springs (just a suggestion though) when you go to .391 / .372 lift, and mandatory when you go to .411 / .391 lift.

Anytime you install cams its best to degree them. Well, degreeing cams is part of installing them. This is preatty much mandatory on ANY cam on ANY motor. It gets you the proper baseline and the best starting results.

well, i know a lotta people (from what i was reading on dsmtalk when it was up) didn't use aftermarket cam gears. cause apparently hks and these cams are cut closest to stock. heard that most people did alright without the gears but i don't have 1st hand knowledge. i for one might just use the stock gears for now so when i get them on, maybe i can post a review.

undecided onthe springs though. wish i had a good definate answer on that. i'd throw them on later for sure but would like to slap on the cams till i could afford the springs too....hmmmm....
