help deciding on cam

[98GSt_4life]

birthdays coming up and and a set of cams is on the top of the list but im not sure which ones would yield the best results for my setup and future goals.

i have all the supporting mods and am currently running a e316g at 24psi and 19 on the street. i plan on going hx35 or one of FP's HTA turbos down the road.

i dont plan on revving to anything higher then 8k

i originally planed on getting BC272's but after reading tons and tons of mixed reviews im leaning towards kelfords or gsc's

As you already know, every setup is different. But I've been pretty happy with my FP2's... can't really go wrong with them or a pair of decent 272's IMHO. (I will be switching to something better suited to my stroker eventually though).

Whatever you go with, get some ACG's so you can degree them and get the most out of them, even if it's just to match the manufacturer's specs.

Don't forget that with some of the higher lift/duration cams (Kelford) will require an upgraded valve train as well.

the head was rebuilt by slowboy with BC valve springs and retainers.

im leaning towards the kelfords because of all the good reviews but after reading about how aggressive they are im not sure ill see as good of gains sence im not planing on revving the car very high.

 

[Calan]

What is your HP goal, and are you wanting the torque curve shifted toward the mid or high end? I'm guessing high, since you mentioned revving it to 8K.

 

[red_devil]

You could also try Delta or DSM graveyard re grinds

 

[JDR7919]

FP2 or comp 101200 they work with the stock valve springs.

 

[98GSt_4life]

i dont want to have to shift very high if i dont have to but like i mentioned i already have BC valve springs and retainers.

Mainly, you pick your cams to your driving style and the turbo/power you are wanting to make it and where you want to make it. You don't want a set of cams that move your powerband to 6k+ only while being on a small turbo and vice versa.

 

[98GSt_4life]

thats why i stated in my first post i will be upgrading to an holset or one of fp's hta turbos i haven't decided yet. but the car is going to be my DD so i dont want the torque curve to high i guess. just looking for a good all around cam that i will still see gains with my 16g.

272/272 in either Kelford / FP / HKS

Cant go wrong with any of ^^...

DSM Graveyard's regrinds are a very good and a good alternative to a cam upgrade.

Which powerband? The hks272s and FP2s have 212-213 duration at .05" lift. The kelfords have 226. That's like saying you can't go wrong with hks272s/BC288s/fp2s. . . If the cam isn't in his choice of powerband then he can certainly go wrong.

Has anybody used FFWDconnections "DKS" cams? They seem to be fairly confident in the quality and performance and a reasonable price to boot.

this is exactly the thing im not sure about. i want a cam that will make good power and and have a nice lope at idle while still having good street manners. the only thing im sure about is that i will be going with a 272 cam and it will just be dropped in until i can afford a set on adjustable cam gears. thats why i decided against BC cams because of the numerous bad reviews.

Im Rockin the dks 272s and they are awesome. the support was great too and they were like 400 witch included the drilling and taping of the intake cam for the cas 2g

You seam to want something in the 212-218 duration. A cam with a smaller lobe separation (more overlap) is what you want. (centerline + centerline) / 2 = LSA The smaller the LSA the more overlap, the more lope and usually the more midrange for turbo motors since overlap increases spool speed. But you get a trade off, in the high rpms where your exhaust backpressure exceeds your boost, you will have some reversion. This will hurt VE.

-HKS 272 lopes more, has 213 duration and has good street manners.
-FP2s have a little less lope, has 212 duration but has slightly higher power band. Still fine street manners

Most 272 regrinds are based on the hks 272s.

This is where most people make their mistake with cams. Each cam has a different profile as you should already know. Lift and duration is different as well. Take HKS and Kelford; sure they both make 264 and 272 cams, but they are 2 vastly different grinds all together. The Kelfords run a very agressive grind and this is over exagerated, but their 264 grind would be similar to HKS 272. Not to mention you would need to run an upgraded valvetrain to run the Kelford 272.

Each cam manufactuer will produce their own grind of cams and just throw a label on them i.e. 262, 272, 280, 288 etc which is something IMO for the buyer to distinguise each cam instead of having to read all of the other information (which you should do regardless)

Before you state you want a 272, figure out the turbo and powerband AND what RPM range you are going to run wether it's on stock valvetrain or aftermarket. Once you figure that you, you may actually want to run a different cam number than the 272 depending on the manufactuers grind.

Always good to degree the cams even if they are "drop in" as every car will have a different setup and measurements for where degreeing matters.

Most 272 regrinds are based on the hks 272s.

This is the exact reason why I went with the Kelford 264/260 cams. actual duration is 216 @ .050, 3* more than HKS 272's.

Do they lope? OP wants lope
