which cam

[Aproductions]

Alright so I am coming to the last pieces of my build and I need some cams. I was thinking of going with delta regrinds because of their price and I heard good things from them. Now with my setup which would be the way to go, 272 regrinds or 264I/272E combo.

I am a little confused on which the benefits of each are so I would just like some quick feedback.

I read this thread:"What Delta cams? 264/272 or 272/272?" but then I have a completely different setup.

Manley 9:1 pistons, Manley rods, 99 7 bolt block, holset H1c (external wastegate is set at 14.5lbs for break in and then I plan to have it tuned around 20), fp manifold, evo 3 intake manifold(stops making power around 6500 i heard).

anyways I am also torn between the Delta 264/272 or 272s.

or BC 272s

sorry for the length.


thanks.

personally i like the 272s for performance reasons but either way it is a good setup... i believe the 264/272 setup has less lag

 

[Tre3zy]

i know one guy that ran the delta regrinds and have problems with it so he went back to the BC 272's....

 

[Aproductions]

what was the problem with the deltas?

 

[noV8undrDIShood]

here check this out.. i think you'll find what you need in here

272/264 would be a nice complement to your setup

 

[Aproductions]

Link doesnt work for me.

but I was also thinking the 272s would be better cause my turbo is bigger

 

[MoparDSM]

Where are you looking to gain? What are you willing to sacrifice? The 264/272 won't give you as much top end as straight 272s, but you won't loose as much bottom/midrange either. With a bigger turbo, maybe you aren't as concerned with the topend.

 

[noV8undrDIShood]

sorry about the link man.. my bad on the above comment on the 272/264 combo.. when i read over your original post i seen evo 3 and automatically assumed turbo instead of intake mani.

but if your running the holset then i would definatly hit the 272's up. allow that turbo to breath.

as far as the link, go up to search and type in cam testing. it should be the fourth link down. "Cam testing: i will be dyno testing:......" very useful info on different sized cams as well as different brands..

 

[Aproductions]

yeah I saw that before.

anyways, Basically I am using 9:1 pistons so I won't be boosting crazy but still like 20psi.

the 264/272 will keep my bottom end but not as much top.

the 272s are the opposite.

I am building this as a daily driver/street monster haha....which would be better for highway pulls and stuff?

 

[noV8undrDIShood]

the 272's.. you really do not loose all that much bottom end with cartain 272 cams like the BC's.. if i am correct, i belive that the kelfords and hks (as well as the delta grinds of these) have a higher ramp rate than the BC's but the BC have a longer duration i believe. so with the BC's you would no loose that much if it will even be very notciable in your bottom end

 

[whe3ls]

if you get 272's get the comp cams 101200's or the fp2's .hks 272 if you can afford them but both the other cams are similar to the hks cams bc's stuff is crap....

 

[Aproductions]

Well I have $250 for cams, and the delta regrinds are that.

I could also get used BC 272 for $250

So I was leaning on the delta cams, but I really do not want to loose alot of bottom end, but I still want top end and my turbo is a Holset H1C at 20psi....so I am torn between the 264/272 or 272s from Delta

get the 272's you wont notice any major loss in the bottom end. Besides were 2.0L motors with big ass turbos really designed for off the line torque? Having the higher compression pistons will also help offset any low end power "Loss" i use the term loss loosly because your not really losing power, just moving the maximum torque to a different spot in your rpm range.

Since you mentioned highway pulls your defenitely going to want the 272's for that. Oh and dont let noV8 misinform you, the number "272" or "264" refers to the duration of the cam, so all "272" cams have 272 degrees of duration. I dont know off the top of my head but my bet is that those different manufactures have slightly different lifts. thats how far the valve opens into the cylinder.

 

[Aproductions]

Thanks for all the info man, so I think I will go with the 272s, I deff will be doing some highway pulls and I was thinking I wanted torque lower but my compression will offset it.

 

[Jermoturbo]

Go with the delta regrinds (272/272), you won't regret it. I have them, and love the way they complement my 20g.

 

[Aproductions]

how is your bottom end power?>

and when do you feel the hit?

 

[whe3ls]

with a fwd, do you really want a alot of wheels spin? with a fwd you rather have power higher so can still have drivability around town.

All 272's dont have the same effective duration. The duration measured at .05". Most 272's are around 212* at .05". But, some are closer to the effective duration of 280* cams.

those mainly being the kelfords

 

[cantgo2fast]

If you wan to get technical yes, I was trying to convey that most "272" cams will have pretty much the same profile characteristics, and the difference between them is not night and day differences in power curves.

I also just noticed you FWD, low end power isn't really useful in FWD cars anyway. My dads jetta can spin the tires in first and second no problem so I cant imagine the traction issues you already have with big turbo and then cams

Another thing to consider would be the DSM graveyard 274* cams $230 bucks with a core....

 

[Boomdeeze]

There is also the Strictly Import Motorsports 275, they sound mean and perform great.

 

[Aproductions]

so delta hks 272s

SIM 275

and graveyard 274?


I wouldn't want to lose that much bottom end so I think the 272 would be where I would want to go.

 

[boostlife7]

id go with the 272's there more of a proven ground

 

[Aproductions]

I know a am FWD but I don't want to have no bottom end, but I still want top end.

I am not going to rev past 7500 so bigger cams are out of the question.

Like I said before, would the delta h272s be better than the 274 or 275s from the other places. Who has these that I can get feedback from?

 

[Junfan]

It all depends on where you want your powerband. If you want less lag and the powerband in the middle of the RPM range then the 264/272 combo is good. Be warned it will fall off quickly at high RPM. 272/272 will come on later and keep climbing to 8500 or so. I think everyone already covered most of this.
