FP2's vs BC 272's

[91-gsx]

I was wondering what you guys thought about these 2 cams? If anybody has tried both? Would there be a substantial benefit to swapping over to FP2's from my BC 272's? Thanks for any information and thoughts in advance.

I run fp2 cams in my 2.4. Did you degree your cams in? If you dont know what I mean search "degreeing cams" on here. You might be able to gain alittle power if you get them in tune to your motor, unless you didnt just put them in "straight up".

Then it all comes down to tuning. I know ams did a 4g63 cam contest, and fp2s came out on top, but there is always alot of variables. Best to make sure the cams, tune is dialed in, AND then if you feel antsy go swapping cams around. Alot of guys just say "I can feel that its faster" ...numbers, times speak a million words.

I actually installed the cams straight up. At the time when I was running my SC61 setup at 17psi on the stock intake manifold, the BC 272's added an extra 2LB/MIN of flow from 5500RPM to redline. Just for a comparison, when I installed my Magnus SMIM after the cams on my SC61 setup, the Magnus SMIM added an extra 2LB/MIN from 5500RPM to redline just like the cams did. At the end, the setup was flowing 42LB/MIN at 17PSI.

If the BC 272's added about as much flow as the Magnus SMIM, they really cannot be that bad as is. I absolutely agree with what you said above about degreeing the cams. I personally would like to just drop the cams in without degreeing them, and I heard from many people that FP2's idle just like stock when they just drop them in and the power is still there. I guess the same could be said about the BC 272's, but I am just trying to find out if the FP2's have more to offer in the power department.

I have sense moved to a EVO 3 16G setup. Do you guys think that I should leave the BC 272's on this setup as well, or do you think that there is going to be a worthwhile gain moving over to the FP2's?

Thanks for the info 1fastlaser.

I guess your running dsmlink with all these lbs per min numbers, I have aem so I dont get those numbers. Thats a nice little gain, but a sc61@17psi dosent even get you into the fun stuff. Man 30psi would have been fun.

42lbs a min on 17psi is pretty damn good I would say. How much are you flowing on the evo3? I would push the limits of that evo3, turn the boost up and tune to 24 25psi on pump if not more, and get some logs/track times/dyno numbers, and then eather degree in the BC's and see whats left, or switch out.

Thats just my opinion. Its nice to push what you have, then look for more, then just switch parts, and never push it.

I used the fp2's last season, they were fine for stock valvetrain, I reved the engine to 7800 on stock valvetrain. However, I didn't comare them against stock cams, I can't really compare them against anything. I droped them in 'straight up' didn't degree them, and the car idled like stock. They were a budget cam in my eye and one of the best cams, if not the best for stock valvetrain cars running small to medium size turbos.

I could have swore kelfords came out on top

 

[T is for TURBO]

HKS 272/272 came out on top for hp and the HKS 264I/272E came in top for torque. But the testing was done with a 16G, and they reached the limits of the turbo. But there are so many variables to really say which cam is best, as it really all depends on what your goals are and what your current setup is. Longer duration cames give you more power up top while shorter duration cams give you more power down low.

But you guys already know that

Yes, I am running Dsmlink. I too wish that I could have pushed the SC61 a lot harder, but the smog stations could all see that turbo a mile away.. I had to sell it along with my Magnus SMIM because of smog. The new setup with the EVO 3 16G has yet to be started. The BC 272's that I have are the same cams that I ran on the SC61 setup.

I agree with you about pushing the setup that you have before moving on to another. I did not get the chance to do that with my SC61 setup, but this new setup that I have almost finished with the EVO 3 16G, will definately be pushed.

The new setup consists of a EVO 3 16G, Extrude Hone intake manifold, and BC 272's. I think all these parts should work well together and produce a lot of torque at around 28PSI. I also have water injection, a 3.5" FMIC, and a cold air intake, which will help with the 91 octane gas that we have.

The only reason I was looking at more aggressive cams for this 16G setup was because of this thread:
http://www.dsmtuners.com/forums/drag-strip/353044-ending-year-high-note-16g-content.html

The 5-7MPH traps over most full weight 16G cars on record, makes me believe that the HKS 280's that he is using are responsible for the added top end. Those are very aggressive cams by our standard when it comes to the 16G.

I am sure somebody had small cams on their 16G setup and then switched out to the more aggressive Kelford 272's. If anybody on here has owned 2 or more kinds of cams for their 16G setups, please chime in and tell us what you thought and your impressions about the cams.

Thanks again

This was a older test, maybe 3 or more years ago, dont even think kelfords were out yet. They compared crower,fp2s,hks,and stock cams I think. Its around somewere. I dont even think the fp3 and higher line were even out yet.
