Default bc 272's over sti cams????

Anyone know if this upgrade is even worth doing as far as power gains go?? I know the bc's are a tad smaller than advertised. Appreciate it guys..

most guys will tell you the bc 272's are more like low 260's from other companies. I dont think they are a bad option for moving the power band lower while having a turbo to keep the breath up still on top.

They are just not true 272's compared to other cams. I was thinking about them because I like a little more power with out the crazy lopes of other cams.

just my opinion.

What would a BC 280 be compared to as far as other companies are concerned? 272-ish?

How about you get a quality cam for a little bit more coin, instead of putting chinese machined parts into your car

Currently in the process of getting Cosworth 276 or 278's installed 'can't remember the exact spec's as the person doing the work has everything.

Good choice of upgrade?

Also I have been informed that Cosworth Cams are prone to seizing?

If you get the Cosworth 272/272 cams you wont need to worry about those issues. Why do you need such big cams what Turbo you going to run. A true 272 cam is big enough for a GT35 sized turbo and you are not going to even max them out,

Is there really that much difference from from 272-278?

td06 20g would be turbo of choice.

also keep in mind it is not a good idea to put brand new cams in with old buckets so figure that into your cost also 16 buckets x 20 bucks apiece.

you know most of your clothing is made in china and a big percentage of the pc or macs we all use come from china.

its all about controlling the quality. just because they advertise there cams as 272's there are a ton of ways to measure out cams and every manufacturer is different. Maybe he is getting the cams for a great deal and just wants to know more info about the cam.

True but they are known for cutting corners.. so chances are something can wrong. Spend more money and get a product thats known for quality and they will last longer.
I am sure you can deal with a tare in your t-shirt but the slighest imperfection in a cam will not have a happy ending.

I am sorry I dont see threads discussing how BC cams have failed because of production or or poor quality. I actually dont see threads saying they have failed period.

I just did a quick search for "BC cam failure" and "BC cams fail" ....didnt find anything, maybe I am not searching the correct terms.

All I see are people not happy with the amount of power they are making with the BC advertised 272's and guys suggesting that if they want 272 power out of BC cams to use the BC's 280's.

I am not a fan boy for BC nor do I own their cams in my car I have just seen the cams in peoples cars and they are great cams if you can get them for a good price. Good is relative and is determined by the buyer. If I could get a set of BC 272's or 280's for less than 400 I would seriously consider them.

well for 1 i know BC's are supposedly a degree off and lift is more of a 264 in other companies. I am more looking for higher duration than lift more than anything. Personally I will prob end up using GSC s2's. But considered BC's just for the simple fact that they are LESS coin than the usual...

What? show me a thread in which someone has issues with BC cams....

You know nothing, I can post many threads of Cosworth cam failures if you want. Cosworth cams sucks period is just an over priced rod, is wiser to get kelford's or gsc's. I would rather get BC 280s than spend money on Cosworth cams

Please, show me one thread.........

I have BC 272 and I don't regret getting them, is better than nothing. I just got them because I could use them with my stock valve train. There have been in my car for 25K and I have not have a single problem, I rev constantly to 7500rpm and sometimes a little more.

Again IMO I would rather spend the money on BC 280 than other 272 cams, I guarantee that the difference in power is minimal, but the different in price is huge. Many top shops use them with success, here are two examples currently in the PBB section:

http://forums.nasioc.com/forums/show....php?t=2054715
http://forums.nasioc.com/forums/show....php?t=2076762

If you want one to get real 280s get 280s kelfords or gsc 3s

I've used numerous bc cams in builds. Never had an issue. You HAVE to break them in upon initial start up with the proper break in lube. Bc 272's are perfect for cars up to a 30r.

I personally put together a 2.5L hybrid motor with kelford 280 cams and it is a bitch to drive on the street. Because of the duration of the cam you need to rev the car to 3,000rpm just to get it going off the line. And let's face it our cars will almost never max out even a crower 272 cam. Which to me crower is kind of on the lower end of the totum pole due to their incorrect duration specs and just them being new to subaru tuning. Cosworth and kelford are the way to go for sure, they don't cost much more than the BC cams and they are a GREAT quality and you know they will last. A 272/272 cam from either kelford or cosworth will support 1200cfm which is about a GT40R and 90% of us won't get to that power level. And the ones that do will spend a **** load of money and it won't matter at that point lol. You can make a TON of power off of doing a hybrid build and porting the heads which is a big key to making power, I cannot stress that enough. Along with some 272's and a good turbo and tune you will smoke nearly everything you come across. A 400-450whp street WRX is damn near untouchable because anything that has the power to beat you on the street can't get the power to the ground before 100mph . Any questions? PM me!

So much fail in this thread if hurts.

For one, advertised duration is what everyone seems to quote and it means absolutely nothing and tells you absolutely nothing about the cams actual effective duration, lift, or centerline. If you really want to pick a set of cams you need to compare those specs between manufacturers.

BC tends to be a tad generous with there advertised duration claims but they are not bad cams and they are much better than no cams at all.
