Best cams for FP3052 setup

[dsmdeliveryboy]

I'm gonna start my FP3052 build on my Talon pretty soon and I'm trying to get all the parts I want/need figured out right now and I planned on getting FP2 cams but now I'm wondering if those will be enough. I don't plan on running more than 21-22psi for awhile, and I don't plan on upgrading my valvetrain at the moment since my head was just completely rebuilt to OE spec(with balance shafts eliminated, ARP headstuds, cometic HG, and a kevlar timing belt). I'm guessing I won't be able to rev much higher than 7.5k RPM till the valvetrain is upgraded.

FP3 cams? Anyone? I'm not sure if 280s would be too big or not for a street car..

280's aren't too big for a street car, they are however too big for a stock DSM valvetrain.

Would I see better results out of 272s or 280s though for this turbo?

Honestly, it all depends on which brand you are going with. I would lean more towards 272's for this turbo, but power wise all depends on which company you are choosing to go with.

For example- Kelford 272's are more aggressive than most manufacturers 280's. BC 280's very well may make less power than Comp or HKS 272's.

You need to lay yourself out a budget and decide what you want to go with. I personally would do the valve springs/retainers while the cams are out and not have to worry instead of doing cams and then the springs/retainers later on.

You need to decide if you want to keep the stock valvetrain and if you are going to go with a bigger turbo later down the road. These will be fairly substantial deciding factors.

Well I found a fully ported 6 bolt head I'm just gonna start building, so now its the question of what kind of valvetrain and cams are best for the 3052?

I ran HKS 264/272 with the 3052 and i would definitely tell you to go bigger. The turbo had plenty of breath but power was falling off a bit too soon (6.5k-7K peak)

I have a set of Delta K272s (Kelford grind) sitting in the garage, which should net me big top end gains.

As mentioned, they're bigger than many 280s. I won't have time to install for a few weeks, but i'll post my impressions when i do.

BTW, $368 shipped, brand new cores, not regrinds.

Ya I was looking into Kelfords, let me know how the gains are. I have some HKS 272's right now I can use, but I've used HKS cams in all my cars and wanna try something new.

 

[400hp93talon]

Why try something new....HKS 272's should be perfect for your setup!!!

I don't know, thought I might go with something more aggresive but if everyone thinks the HKS 272's will do ok then I guess I can try them for now. Just need to find me some springs and retainers etc now.

 

[Yngvar]

why not FP2

 

[dsmdeliveryboy]

I honestly don't know if they're more of an upgrade over the HKS, that is kind of what I was trying to find out.. Haha

 

[kahl23]

The time in my profile on HKS 264/272s and a really rough tune. The next run a misshift trashed the head so now we're using 272/272. I'm really looking forward to seeing what the car can do with this setup, but I feel that 264/272s are a bit on the small side unless you expressly want a lower/relatively torquier power band.

This thread is relative to my interests as I am in a similar boat.

GSC had told me that their S1 cams would fit right for a good bump in both peak and midrange. Says good to 400hp which is lower then a 3076's rating.

And this also brings up the Kelford 264/270 combo. These have the same intake lift with less duration and a bit less exhaust lift with a longer duration compared to the GSC S1. These say good to 500hp which is right around the limit of a 3076. So it is an interesting comparison.

But, both of those estimated hp limits mean nothing if you are going to run moderate boost.

Someone PM Monster to get in here

I found some FP2x cams for sale for a really good deal, maybe I'll jump on those.

 

[BoostFrenzy]

Being that you are just up the coast from me, I would advise not to go with those. The 2x's have REALLY steep ramp rates and cause a lot of knock on pump. Especially with our shitty 91 octane here. Darren P up in Canada has the FP1X's (last time I checked) and he HAD to switch to a meth injection setup so he could run decent timing and boost numbers because of the knock that he had ran into.

If I remember right, I believe an E85 station just opened up in SB so that is always an option if it really is a good deal on those x's.

I plan on running meth not long after the turbo is installed, but sounds like I may just use the HKS for now just because I know the car runs good with the HKS cams in it. One thing I do like about the HKS cams is I felt improvement through the whole RPM range, not just in mid and high. Same with my old Evo too, same cams and same gains.

I heard the FP2's have a little longer duration than the 272's but are pretty similar. If anybody knows the exact difference please chime in.. I run FP2's with an FP Green at 26psi on E85 right now and I have my redline set at 8250. It pulls like a raped ape and builds power ALL the way to redline. I do have a custom intake manifold so I'm not sure how that affects the power curve up top..I love the FP2's though..very streetable!!

 

[dsmdeliveryboy]

What intake manifold are you running? I eventually want get a street SMIM

 

[TSIfreek]

I would say the keford stg 1 264/270 combo.

Am I gonna see a better powerband and gains through the RPM with those compared to my HKS 272's?

Yea I would rather have the kelford stage one cams over the really old technology of the HKS 272s. The kelfords have diffrent ramp rates on both the opening and closing of the valves as with the HKS they would be the same and the kefords are machined much more accuarately than the HKS cams.
The stage one cams would be the best choice using the stock 6 bolt intake as well.

 

[dsmdeliveryboy]

Ok cool, I'm gonna look into them some more. Man I was attached to the HKS powerband too haha, hopefully I feel an improvement.

 

[autotalon]

I doubt you'll see much of an improvement. They are basically the same cam. The Kelford cam has an actual duration of 216, where the HKS have ~213. So the Kelford's have about 3* more.

I upgraded from HKS 264 to the Kelford 264/260 set along with a SMIM and gained roughly 30whp once dialed in correctly.

Also, we found that the Kelford set is on the same center-line as HKS'. The best position for both cams were at -4,-4. for a gain of about 10whp.

HTH.

HKS 272 < FP2 < FP2X

The 2x is the most aggressive of the three. My brother still runs these and they are kickass. He has them on a 50trim setup.

I went from the FP2s to the 4Rs. I'm ready to finish my build. AFAIK, FP doesn't make the 2X grind anymore.
