FP2s or FP2x?

I guess what I am trying to say is, do you really think its worth upgrading the whole valvetrain just to use the 2x cams?

I think that it would only be worth it if you are planning on reving higher than 7500. I don't think that you would benefit to much for the money just to get the x's in there.

I think I'll just stick to FP1x or the DKS 264/272 combo. Thats alot of money in the valvetrain! I guess what I am trying to say is, do you really think its worth upgrading the whole valvetrain just to use the 2x cams?


Not with a 16G.

If you were planning on running a large turbo, then yes, the ability to rev to 9000rpm+ (and make power at that RPM) would make the 2x cams a great mod.
 
Since we are on the discussion, I know this has been discussed a million times, but what is the benefit of going with a 264/272 setup as opposed to a 264/264 or 272/272 like set up?

2.1l motor, comp 101400's, Manley single spring, 9500 RPM's no issue.

Manley and BC single springs work well, but I have no such experience in my own car with BC as of yet!

What did you set the valvespring installed height at?

the 264's are suppse to be a 'mild' upgrde from stock, some people think the 272s are to hardcore for the street, trust me they are not. For the different in performance numbers it is almost stupid (IMO) to go with the 264s, with the 272s the idle is affected a little bit but not where it will die on you in the middle of the road

I agree, unless you are going to be sticking with a 16G and then I would go with 264/272's. You end up loosing to much torque with the straight 272's and only end up gaining a couple of extra horsepower (maybe one or two)

With the set-up that you have though, I would definately go with the 272's. With the motor combo that you have and that turbo then you should be putting down some really good numbers with those cams.

I don't know if this is relevent but I went 8k all day on stock springs and 272s.

Thats crazy, im too scared to rev that high on a stock head, i took my car to 7.5k max and it hit like a fuel cut off point in the ecu, and i didnt like the feeling, felt like i was hurting the engine....

I've had both... The fp2s I have with Manley singles work great to 9K The FP2X require the Dual springs because I experienced valve float @ anything above 7600rpms So I sold the Fp2xs to my buddy who has duals and they run nice on his setup... The lobe on the Fp2x is alot more Square than the regualar fp2s... You WILL NEED the Duals to run the Fp2xs.. Forced performance even had to put a REQUIRED on their website because people like me bought them and Could not run them because of the single spring setups...

So im sure you've been thru a couple rebuilds huh....

So hes saying to go with 264/272 or disagreeing? I think im going to go straight 272s even though i will only have a 16g in the near future.... I trend to build my car for future needs not current needs, hows idle on that cam combo oppose to stock... Does it give that hard lumpy v8 idle with these cams, or is it still someone normal?
 
you will get a lope, but depends where your idle is that that really affects it. Reving high rpms isnt that bad if you take the precautions, like the dual valve spings, but the main concern is the transmission, most transmissions have 100k miles or more and cant really take the fast shifting, so you have to let the rpms drop.
 
just for the sake of information in this thread:
For a set of FPx Cams and their dual spring kit the price is $794 + shipping

For a B.Crower set of 272s or 280s and their spring and retainer kit its $545 shipped

So when considering this, you really have to thing about your goals for your car. I can think of pleny other places I'd like to spend the extra $250 I'd save by going with the BC setup. (Meth injection for one)

Sometimes its not always about the money but the peace of mind... I was thinking the same thing and decided to go with FP2x's and was going to go cheap the springs. But decided to just shell out the extra for what is known to work well.. and got the FP's Dual Springs. So now I dont have to worry about not being able to rev to 9k or anything else...

Perfectly said. I have a head with oversized valves, cams, big port job, and when i was considering cams, i figured i might as well go with the titanium retainers and dual valve springs. Now im rebuilding my moter, and the peace of mind thing came into play, instead of keeping my stock 1g big rods, i decided to go eagle hrods wich will support up to 650hp or so, now i know im not going to need that, but i will never have to question my rods, one less thing to break off the list, now 6billion things more to go
 
I think crower is proven enough for me. Afterall, they have been making this stuff longer than FP... I think crower as been around since what, the 40s?

Not dissing FP or you guys, but I have plenty of peice of mind using bcrower cams, springs, and titanium retainers.

However, I do not belive in skimping, I rather be pushing 400hp on a 650hp rated set of rods as opposed 400hp on a 400hp rated set of rods. Like you said, never have to question.

FP Cams are actually made by Crower... Comes in Crower box, same material as Crower cams... Only thing different is that FP Design the cam specs... and Crower made them to that spec.... So really its a Crower Cam...
 
TSIMonsteR said:
I thought comp made FP, not crower!? Comp Cams and Crower are two different companies.... I may be wrong, but I am almost positive. . .

I'm sorry your right Comp. Got them mixed up

I was saying that if you are going to stick with the 16G (like a lot of people end up doing) then I would go with the 264/272 combo. When you go with a bigger cam set (272/272) you only end up gaining minimun horsepower over the 262/272 but end up loosing more torque than what it is worth.

I ended up going with straight FP2's in my car and gained a lot of power from them, especially over 6,000 rpms where the stock cams were chocking the motor. I plan on going with at least a 50 trim at the beginning of next year though. If I was planning on sticking with the 16G then I wouldn't have went with such an agressive cam on the front side in order to keep some of that torque.

I was agreeing with going with the 272's for his set-up because he has a turbo that can flow enough to take advantage of the 272's especially if he is going to be reving over 7000.

Just thought that I would clarify what I said. :thumb:
 
your saying anything bigger than a 16g would benefit more from 272/272 ? Because those are the cams i was considering getting, and i am also planning on getting a turbo bigger than a 16g once i upgrade from the 14b.
 
The B just stands for Brian as in Brian Crower. I started a thread a little while ago about the same thing "FP2x worth the money" or something like that I called it. The fact of the matter is Dsm-onster has been running his fp2x's with great success paired only with manley spring and stock retainers. This is not with a stock rev limit either I think he may have been going to 8k. If you have manleys go fp2x it should almost be a no brainer. Especialy since the cams cost exactly the same ammount of money. Call up Manley ask for the specs on the springs compare them to what FP says you need and then get the piece of mind your lookin for.
