Recently got back from some testing at FP in Texas. I have been running the FP2's for a couple of months and was there to upgrade to the FP3's. We had scheduled in some dyno time to see what and where the differences were.

So here's the setup. Day 1. FP2's at 20 psi. Day2. FP3's at the same settings. So here is the dyno sheets of the two cams overlayed. Intake temps for FP2 test day was 84 degrees and intake temps for FP3 test day was 92 degrees.
Basic Setup:
2.4L long rod 10.0:1
Stock 1G intake manifold and TB
2.25 inch IC piping
Precision SCM61 - P trim turbine - internal gate
Polk stage 3 head
DSMLink
FP Prototype Valve Springs.
20 PSI



My clutch is dying so we didnt really get to push the car on higher boost. We made one run at 23-24psi which netted 506whp and I cant remember the torque numbers. The clutch was having no more of it.

Hope this info is helpful to those of you who are in the middle of choosing a set of cams.

Thanks for the info on the cams. I was actually wondering how they would fair on the big end compared ot eh other cams but i ma pleasently surprised. If they can offer a set of springs that will put up with the cams I will be even happier. Thanks for the post.

Impressive, the low-end power and torque arent effected.

Jeff, can you give me some more info on these FP springs?

I bought some of these with my fp3......

The FP Prototype double springs are 100lbs @ 1.540 and 250 @ 1.110. In comparison, the Ferrea's which I "was" going to use are 90 @ 1.540 and 210 @ 1.110. I didnt use the Ferrea's because they need to be put on when the head is off the car. The springs were WAY to close for comfort to the cam towers. Plus the FP springs cost less.

I dont understand the difference between the fp2's and the fp3's. Is the fp 3 just like the fp1 for a stroker? I thought they were making fp4's for the 272 guys.

The FP2 is like the 272 and the FP3 is bigger. They look square.

So you can get an fp3 for any 2.0 liter?

Against FP's recomendation I went ahead and ordered one. They simply stated they hadn't done it and they didn't know what would happen, they also said that the fp3 was a cam better researved for a hotter motor than mine. They said they were better suited for engines like swordfish high compression/race gas/track car, not a good street cam.


Swordfish how does your car idle?

Was anything said by fp regarding wear on the cam journals from such a tough spring? I am sending the head to be worked on and would like to get my spring decision made. I am also intersted in the idle characteristics, but I am sure there wouldn't be much lope.

My car idles great, but then again its a big displacement high compression setup that still pulls a lot of vacuum at idle. It's still super driveable .. my wife can jump in it any time, fire it up and go wherever she wants.

FP didnt mention anything about cam wear, but I'm not worried about it. Robert wouldnt make it available if it wasnt quality.

I was more refering to wear on the head itself since our cars don't have roller cams. I need to shoot them an e-mail anwhow so I will see what they say. Thanks again for the great comparison,

Swordfish when you unwrapped your cams was there like any thing in the package or on the cam at all signifying these are Forced performance cams? Every thing I got says that i recieved comp 101300's. No trace of the big "FP"

When I got the FP2's they were just in comp boxes. We put the FP3's in the car at Forced Performance so I didnt look to closely. Scott just brought them out in comp boxes and we got to work.

jeff

Nice numbers, I can't wait to see the difference when I go from stock cams to the fp3's with my stroker motor...

Anyone else notice how the fp3's made the same power as the fp2's only 1000rpm sooner (refering to the fp2's peak power...)

Damn thats a nice torque difference,even 19hp is a big difference....i got the same setup minus the long rods,10:0.1 comp,and im running a 60-1 p trim turbine,but im sure i would net a difference,how is idle,driveablity?

Idle and driveability are great. Car is just as tame as with the FP2's during normal driving but the new power is noticeable. Also notice how much power under the entire area of the curve the car picked up. Big difference. Did I mention how much I love these cams?

jeff

Being that I am forced to snatch my head out this summer, what do you think about me putting some fp3's on a regular 2.0 liter with stock 1g compression ratio? I am deff. putting cams in this thing since I have to pull the head to have the machine shop replace the valve stem seals they screwed up the first time. I would like some more topend than the stock cams that I have in there now.

it might not be worth it,the only way to really tell is run some fp2s then go to some fp3s like swordfish did.Hell if you go fp3s and dont like them,ill trade ya my fp2s

Yea, I might email fp in the morning and ask if they did any testing on the 2 liters yet.

Their only researve was that it hadn't yet been done and wouldn't risk guessing what would happen, if it sucks they aren't gonna give me my money back.

I'm thinking due to the increased ramp angle they are more suited for the strokers. For the main reason that you will probably get valve float much sooner with the FP3's. I've been going back and forth on this one. I really like to kept the high end the 2.0 has. More usable powerband with a large turbo. Kept us informed on your results.

If you plan on revving more than 9k go with the fp2, but just look at swordfish's dyno, he makes more power at the top in the middle and on the bottom. Even at 8500 it looks like the curve has less drop than the fp2. I know personally i will never need/want to rev passed 9k so I went ahead with the purchase. The valves stay open longer, that means more power no matter what size engine you are talking about.


I also have a built automatic so streetability is a non issue for me. All I do is blip the throttle and my engine goes straight to 3 grand (4500rpm billet torque converter).

let us know how it drives, maybe post a vid? I will get some if they are decent. My car has always ran like shit, so I will fix it and then get the cams so it can ride like shit but be faster.

Hey i was just wondering, up to how many rpms do you take that 2.4?
