Which cams to use? FP3 or S3?

[93'colttsi]

I know its a bit overkill for my current turbo setup (E316G), but I have two sets of good cams in my possession now. These are the FP3 cams and the S3's. I will be going to a much bigger turbo setup within the next 2 years, so I am trying to use the parts I have currently in this build. I have no experience with either of these cams, and am just wondering if there are any advantages between the two on a smaller turbo setup that I will be running. I will be running pump gas and methanol. Shooting for 27-29 psi and hopfully 350 whp. This setup is going into a FWD 93 dodge colt coupe w. 2g FWD turbo trans (stock)

Setup:
6 bolt (stock big port head/intake and block)
Kiggly beehive springs and ti retainers (hoping for 9000RPM)
E316G w/ evo3 o2 and 3" exhaust with e-cutout test pipe
Evo 3 full aluminum FMIC kit
785cc FIC injectors
walbro255HP w/ re-wire
AEM meth kid v2 w/ 2 injectors
eprom w/ ostrich running Sweedensity w/ 3 bar map

Let me know what you guys think. Car will be mainly used for track use 1/4 mile and street duties for now on this build. a year or two later in will go a stroker motor w/ big turbo and awd running 600+WHP

It will the opposite effect. You will have no advantages. Instead, you are giving up all your bottom and mid range power for only a little taste of the upper band until your turbo runs out of breath around 6800rpm.

Leave them out and run something smaller.

Hrmmm, well that sucks. Any recommendations on cams? (I imagine stage 2 cams would be in order, around a 272/272 duration ish?)

I will be using Kelford 264/264 cams for 500 awhp but thats in an auto AWD. FP3's are way too big for your goal, I made 581 AWHP using FP2's and I revved out to 9.5k using single BC springs. I did this many times over the 2k miles before tearing it down for a new setup.

 

[93'colttsi]

haha, well maybe ill have to ditch the evo316g and buy a real turbo .


So pretty much what you are all saying is that I will make more power with the stock camshafts (1990's) then with the s3's or FP3's? those are my current options.

That's a lot of boost to try to run on that turbo. You may find yourself with a snapped shaft in the not too distant future.

The cams move your power band. With those FP3's are are going to move your power band higher to a point where the e316g is not as productive. FP2's would be better or even some HKS 264's.

 

[lasthope05]

I would go with cams in the 272 range such as: HKS 272, fp2/comp 272, s1, kelford 264...etc. These cams will give you a nice broad power range.

With the 16G, the stock cams are great. The 1G cams are fairly aggressive and don't NEED to be swapped out unless you are running bigger than a 20G, but even then its arguably minimal. 2G cams are less aggressive. 1G's are like .010 higher lift.

264's seem to be a good choice for the 16g http://www.dsmtuners.com/threads/16g-turbo-what-cams-do-you-run.416209/ http://www.dsmtalk.com/forums/archive/index.php/t-123491.html But the 1G cams will be fine and you could make more power putting the money elsewhere.

Okay, well sounds like ill leave these big boy cams along for now until I can do a bottom end build and get a turbo capable of flowing air up top that those cams need.

For now trying to track down some HKS 272 cams if possible. (should be more suited for a 16g evo build I would imagine.

Thanks guys!

Just for curiosity, which cams are better? Fp3's or S3's?

 

[93'colttsi]

Okay, let me change this question up a little

Say turbo is the evo 3 16g.

Would the s3 cams make more power from 5500 RPM to 7500 RPM , or would the s2 camshafts make more power in that RPM range.

said that, I figure when im racing the 1/4 mile, I will not be using RPM's less then 5500-5000 rpm besides for a very short while off the line, which will be spent spinning the tires for the most part anyways (FWD w/ slicks). Im also not going for low end power and torque here. It is a 7.8:1 compression 6 bolt, with the 1G big port head. Im going for highest HP numbers and peak power!!

Just sell one of the two, and your 16g and buy a bigger turbo, youll thank yourself. I dont think you can go wrong with either, both are from great conpanies, the FP's are made by comp cams. They are just better suited for turbos like the 35R and larger, or with a stroker.

Hmm if the 1g cams are more aggressive, I wonder if they'd better suit my setup. 2.4l with a 1G head and Cyclone IM.
