The Crower 280s have a shorter advertised lift than the Cosworth 272s.

10.8/10.3 for the Crower and 11/11 for the Cosworth...

But keep in mind that lift is not really what creates the power, the proper duration has a much more important affect. Long durations will move the powerband towards higher RPMs. If you have a big turbo that is still making power past 7000RPM, you will want long duration cams such as 280s. If you are on the stock turbo or a turbo that runs out of breath at 7K, then 272s are better suited, because the longer duration, the worse your bottom end is going to be.

I got these because I'm going to be on the Evo Green next spring, and I will be RallyX and road racing... I don't want a cam that destroys my low end power, so I can't go 280s.

As far as lift is concerned, I'm not concerned that the Crower is lower than Cosworth... HKS cams all have very similar lift specs, ALL their cams from big to small... more lift is really only needed with a ported head and a lot of airflow.

 

Funny i found this thread, i was looking at the BC cam's recently for my EVO.

I know BC cam's are great for Nissan's, so i figured they would be decent for the EVO.

I am still unsure what cam's ill be getting but they will probably be a 272 duration. I might also be running a Green. I have a 2.3, Looking for good response across the board, till about 7000-7300rpm

 

Get some cosworths and a green. Then get some sticky tires cuz it's gonna be a torque MONSTER!

 

edit cosworth and insert gsc s1 too.

 

If you want a good torque cam, I would say HKS. They produce more torque than the cosworth it has been kid tested and mother approved .

If anyone is looking into testing the brian crowers, I would give you a great deal on the cams, installation, and tuning. Let me know.

 

And this is documented where? Every HKS I've seen did not make as much as the cosworths

 

the 280's shouldnt be a problem unless ur reving past 7800 rpms...


those going with larger turbos and reving to 8000+ should get them....


I'm debating on the 280's and keeping the stock valvetrain

 

This is documented on the forums. Search and you will find results.

With good supporting mods, I wont rule out the HKS making more torque and power than the Cosworth. Plus the HKS have a better and smoother feel. Also, Idles alot better than the Cosworth almost like stock.

 

bump for more info...still debating the 280's vs the Cosi's

 

i might go with the 280's

 

Just ordered some brian crowers 272's from gruppe-s so i'll post results after install and tune, and prolly dyno graph

 

Be on the lookout for a review of these guys... I do my own tuning, and I'm quite sure I've tapped the stock cams to their full potential.

This oughta be good.

 

I have 272's on my evo 8. I just recently put them on so i am not tuned. They idle better than any other evo ive seen with cams. People can't even tell that i have cams

 

I'm buying these 272 sets for my Evo 8, I'll post up Dyno results when done.

 

I just installed my brian crowers 272s mivec cams, and they are nice, more power up top and they are lopeyy sounds like a evo 8 with them
