HKS 264/264 or 272's or FP2x w/7cm FP RED ???

[NJdsmguru]

I'm running 264/264 w/fp red. Should I go 272's? Heres my mod:
Ross 9.0:1 pistons
eagle rods
hks 264/264
4 layer hg
arps
7cm FP RED
ported 2g manifold w/hks 40mm ext
ported 1g o2 housing for tdo6 wheel
Full 3" turboback
FIC 750cc
MAFT/afc/keydiver eprom chip
walbro 255 hardwired
full throttle fpr
msd dis2
Spearco 2-216 fmic
NOS wet kit

Car is weekend warrior and will be tuned to run 30psi on c16 would i benefit from from 272's or fp2x ?

You would benefit from both over the 264s. FP2x grinds are gonna give you more power than 272s becuase they are a squarish lobe cam, and have quite a bit more lift. Fp3s might not be a bad idea either.

 

[NJdsmguru]

Aren't the fp3's designed for 2.3 or 2.4 strokers?

 

[TSIfreek]

FP2x, FP2s or the 272s. The 2xs will be more top end happy.

 

[ericbev]

Both would be considered a smart upgrade seeing as you are running a turbo as large as the FP red. Your powerband is in the upper rev range where these bigger cams really start to shine. The 2X and 3 versions recommend dual valve springs, while the 3X requires them. The 3 and 3X versions are specifically designed for the 100m stroke. Here is a link of a guy with a stroker that went from 2s to 3s.

You could just ebay/trader your 264s, pick one of the above cams up with no significant financial hit, and gain some nice results.

My vote is for the 2x's as that is what I will be running this upcoming year

 

[Lunch_Box]

I also vote for the 2x's. Bit more top end and save yourself some money.

 

[blcknspo0ln]

well, that list doesn't include a built head.. I thought the fp2x's were meant for a built head..

is anyone running the x's on a stock head? if you are and are having good results.. PLEASE POST! I was dead set on the fp2's, but if the x's are good with stock head maybe i'll jump on that

Me too Along with a 7cm FP RED

 

[Slippi84]

I am in the same boat as you. I'm lookin to upgrade cams and am stuck between 272's which are probably the most proven dsm cam and the cheaper and actually better top end fp2's. By the way is that 3" intercooler piping you have if so how do you like it I'm really thinkin about doing it myself and we live real close I wouldn't mind meeting up and checkin that out.

 

[gSx_r1der]

I know a guy running the fp3 here in diego with stock valvetrain and that is most likely the cause of his car running funny right now. He loves them though, and I just picked up the 272's from rre a few months ago and absolutely love them. Driving in traffic and in parking lots sucks but its worth in my own opinion. With the fpYx arent they required to run their dual spring set???? Just curious. And if your going to get the dual spring set why not just run the fp3x and never get it idle right

I've got the HKS 272's and they drop right in and run great and idle at 900rpm. However If I could I would go with Crower stage 3's, the 414's. 272's have 213* duration, in/out. The crowers have 218*/216*, in/out and may idle a little rougher but make more power all through the range. By the way my 272's are still pulling at 8350rpm when I shift so be prepared for 8500rpm shifts, tranny up to par? All of the cams mentioned are good for more than the 272's for higher rpm's. mark

 

[CanadianTSi]

There's a guy on here running FP2x's up to 8500 with Manley springs with no problems.

I plan on buying the manley spring/retainer kit and only revving to 7550 for now so it should be fine.

 

[NJdsmguru]

I think I'm gonna go with fp2's because i don't have the extra $$$ for the valve springs and retainers .

 

[Slippi84]

One problem the FP2x's strongly suggest/require dual valve srpings if you want just drop in cams I would go 272 or FP2's. Now tell me about your piping dam you .

 

[ericbev]

Their website says it right there. The 2X and 3 versions recommend dual valve springs, while the 3X requires them. The 3 and 3X versions are specifically designed for the 100m stroke.

I am curious to exactly how much more power you get from the x version of each fp cam. I am either getting fp2's or 272's next week and seeing how I have a rebuilt head and don't feel like messing with the valve train it would take more than a 5hp diffrence between fp2's which are already known to be ok with stock stuff to get fp2x's which reccomend(which means if you #### something up and you have stock stuff it's on you dumb ass).

 

[1SloColt]

There will definitely be a 5hp difference between the FP2x cams and the FP2s. The FP3s were designed with the stroker crank in mind but they work very well in 2.0s that have the supporting mods, i.e. valve springs/retainers, turbo that flows well(+60lbs/min), plenty of fuel. The FP3s are square lobed, which means they keep the valve open longer at peak lift than FP2s or 272s, so expect big torque gains. The FP2x cams have a similar square lobe profile but even more lift than the FP3s, expect big gains. Quoting a buddy I know that runs them, "The FP2x cams have more power at 15psi than the stock cams at 20psi".

I am running them with manley springs. No valve float. Revs very, very smooth. I have thousands of miles on this setup now. SBR told me directly, "You can run that cam to 8500 all day long." they have These springs on all their shop cars. with hks 272s with much higher rev limits than 8500.

I also the guy that was quoted, "The FP2x cams have more power at 15psi than the stock cams at 20psi." This was a butt dyno experience. But I honestly begin having trouble hooking up in third at 15 psi with my 18g. Before i was running 20 psi and third wasn't nearly so nasty.

Run what FP recommends or what SBR recommends for springs. They both have been doing this longer than many of us put together.

To the original poster. FP2Xs have the widest lobes (broader power band: adds power below and above the typical FP2/hks272 powerband), highest lift (most instantaneous flow: torque), are "drop in" (FP swears that they do not have to be degreed), cheaper, come from a shop with the best reputation in the DSM community (next is SBR, IMHO). . . . Finally, my car is fast a sh!t. I am so impressed. And I havn't even dropped my 60-1 (FP RED compressor) in yet. I know these cams are carrying my 18g to the limits and the Manley single springs are more than capable of the task.

 

[NJdsmguru]

i just picked up some Crower Stage 3 cams w/fidanza gears instead of fp cams.I gotta good deal on them.

 

[firebirdvert305]

tell us how you like them....get some video too we all wanna see.

 

[sweet97]

Correction to my post above. I stated the Crower stage 3's, the 414's had 218*/216*. Well I bought them and changed out my HKS 272's but they are the Stage 4's NOT the stage 3's. They also have lifts of .425/.416 compared to the HKS 272's .406/.386. Little rougher idle than the HKS but some extra fuel smooths them out if needed. Have not driven a lot because I am near Syracuse, N.Y. and the roads are not often good enough yet. In another month that should change. There is a post on tuners where a guy with a stroker had 272's and changed them for the stage 3's and picked up 20+ hp. Do a seacrh for Crower. Mark

 

[CanadianTSi]

Just to add a tidbit of information, the FP2x's have a lift of .416/.400.
