So I got my eye on the fp3 cam.....

[definitiveno]

What do you guys think, should I give it a go? Heres a little info on my car....

Head: huge port and polish, 3 angle valve job, 1mm over sized valves, bronze guides, si dual valve spring kit, fresh build.........

bottom end: 9:1 compression, clevite bearings, forged.........

EMS: dsmlink

turbo: gt30r or a gt35r, haven't made a purchase yet....




I talked to corey over at FP momentarily and he thought the 2's would be easier to get results out of, these cams need lots of tuning to see the best out of them. I told him I would have shiv degree my cams and give the car a tune since i don't think I have enough prior experience to do so myself......

I guess this cam is supposed to be the shit, what do you guys think.......

The FP 1's and 2' are for 2.0L engines. The FP 3's and 4's are for strokers or 2.4L engines. I guess I would make my decision from there. You did not state which engine you have. No experience with the FP cams, but with a few different combinations of HKS cams. Those are great in my opinion.

The FP3's need super stiff springs, something 90lbs. I think ferrea is one of the few that has springs this strong for a dsm.

 

[Lunch_Box]

I think you would see better results with the FP2's. The FP3's are made for the bigger engines so I believe they put the lower redline into affect when making the cam.

 

[definitiveno]

You know I had no idea a cam was aware how many cubes were in a engine. Basically, from what I understand, the fp3/4 cam is similar to it's FP1/2 counterparts accept it opens and closes the valves at an accelerated rate. Some thing about steeper ramp angles and that is why they require really stiff valve springs.



I guess this increases the duration wich makes the valve stay open longer. That is good for all motors trying to make power.


I suppose now is time for pro's cons before I buy any thing


pro's: narly cam, supposed to have decent low rpm manners, great top end, make great numbers

Cons: Nobody else has done it yet, so it is like uncharted waters

I run fp3s in my 2.3 and you notice some low end loss but you really cant tell it cause of the 2.3. but they are great cams for the price

 

[Staytuned]

Lots of disscusion on other DSM boards about these cams and proper valve springs to deal with the ramp speed of the lobe. Most people are saying you will need a 90lb seat pressure on the spring and Ferrea is the only company now to make them. I would go with 2's if your thinking gt30r or 35r.

 

[rsTurboLaser]

EDIT: Nevermind. (Deleted first part of my post. Second part remains.)


I suggest FP2's for a 2.0 motor.

 

[ACKERSON]

I would call comp cams since they make the cams. Ask them if it would be a good choice for your application.

 

[definitiveno]

From what I gathered from FP, the fp3 cam has the same profiles as the fp2, only longer durations. The duration is added via accelerated ramp speeds, must get some narly ferrea kit. On the stroker motor the fp3 made 100 lbs more torque at 4000rpms than the fp2, and when I asked if the same advantage of longer duration would be helpful to a 2 liter they said yes and declared that they haven't done it before so it is all in theory. They also said they have taken this cam on a stroker to 8500 rpm and sais that the only reason they don't go higher is because of piston speed and so the application didn't require it to go higher.


So far every thing they told me made me want that cam, the only thing unpositive they said was fp2's will be easier to tune and they have never put this cam on a 2liter.


I want it..... I want it, I want it, I want it.

I have yet to hear convincing arguement why not to install them, FP certainly didn't try to give me one. The only expressed concearns were of thee unknown.......so...

Staytuned, where can I find more reviews of this cam, I couldn't find any thing on talk, and also is the seat pressure more important than liftrd?

Oh wait a minute, what do you guys think of this spring kit?

if you have access to NABR you will find info there.

Too late, bought the cams and springs this morning. I found out AMS is using these springs in there evo race heads and I went for it......


Should be up and running in 2 weeks........



Later

Did you get the Fp3 cams? If so let us know how they are working out for you. Thanks

 

[Batty200]

Well FP now offers a dual spring and Ti retainer setup for the FP3's for 375 and it includes spring seats and NO MACHINE WORK IS NEEDED to install them. I opted for the FP2 only because I didnt want to spend the 400 now (I am broke).

Comp told me the FP3's accellerate valve train wear. how much i didn't get. iWould try 'em!!

 

[tmizer]

FP3's with Manley's here. Measured seat pressure, no shims, is better than advertised Ferrea's. Months ago, I posted a graph here .

Head (1g) has even heavier 2mm o.s. valves.

Engine (built 2.4) runs great, and so far have rev'ed to 7900 rpm.

 

[talon_boy69]

well guys...I don't know...I've been for a while looking for cams...and comp/FP sounds good, but I compare them to ADFX...(a new company, new intercooler, new design and everything, and the claim 95% eficiency at 3mph or something like that) but insted, comp/FP isn't new, but they release this cams, better than any other one, with no lumpy idle...don't know...I've found compr 100200 for like $300 used but this thing on my head...

 

[TSIfreek]

You guys are really something. You guys would put a pro stock cam in one of our engines if it would fit and just to say you have it. I dont get it why spend 450 on a set of cams that is desighned for a diffrent motor with diffrent needs. Just because its bigger does not mean its right for your aplication. I can understand if your building a low 10 second drag only motor than maybe but really who is doing that???? I dont see the need for the FP3 cams in a 2.0 everyday street car at a average rpm of 4000. Even with a biggger turbo. The FP2s pull to 8000 so why fk with it its a done deal. I know guys will try the 3s, but not worth the torque loss in a 2.0 motor IMO.

 

[talon_boy69]

Well...in my case I would buy the cams that would give me the best mid/peak hp...why do you want to have "torque" ? you'll just be cruising if you;re under 4k. Also, why spend 500-600 for 20-30 hp if you can have a bit more by the same price...it's like arguing why you went 272 instead of 264. I've broke my turbo like 2 times and I have an N/A mannifold with all the flanges and everything ready to be n/a when that happens...and I can drive happily over the city or highway on stock 8.5:1 shortblock...even with A/C

 

[mavisky]

I told him I would have shiv degree my cams and give the car a tune since i don't think I have enough prior experience to do so myself......

You might be surprised at the results you could get yourself as compared to Shiv

 

[DarkLaser]

I too was also thinking of running the fp3's, but I have a 2.3 with weisco pistons and scat rods. I Just got done building my cly head and bought the JAM springs and tit. retainers. I was wondering if these would work with this cam or will I ahs to go with my original choice of the fp2's

 

[definitiveno]

I wish I had my email saved from FP still. When I called over the phone and talked to the guys over there was right when the cam had debuted and was only still on test cars. about a month later I got a reply from an Email I sent about the cam and they told me hell yes, run it! They said results from customers kept comingf back with no loss in torque in bottom end, and that they actually showed improvements.

He said they idled identical to FP2's.


TSIfreek, you keep your fp2's, I am anxious to get my car back already. Turbo came in today too

 

[Hammer_Gaidin]

I am running the fp2 comps with si dual springs and manley tit retainers with stainless valves...i've reved to 8500, alot with no prob. I did notice some low end loss.

Why do you rev to 8500 alot?
