Brian Crower 272 Combo

[VETTE_50_TH]

So im looking to purchase some cams for my remanufactured head i bought in the classifieds for CHEAP!! It came with everything except cam gears, however, to my questions. Is it worth it to by 272 in the first place for a street car mainly, and little track? I want around 350 on my evo 3, and bigger once i go to the 3065 probably end of the year. Secondly, i've read that the cams are all right for stock springs. Would it hurt to go to the upgraded BC springs? If so, what do i get out of going with them? Thanks, thats all the q's i have for now.

On an Evo III I would say go with the 264/272 combo. It is what I plan on going with and my goal is 380whp

I just bought a set today, because well...they were a good deal. I can't see why not having a good cam would be anything but beneficial

 

[VETTE_50_TH]

I plan on something bigger by the end of the year. The 272 combo is better for the 3065. Plus, what about the dual springs then, would the be a good thing to have or no?

[drewvr4]

its always a good thing to have, don't have to use them but yea its always better

Here's my 2 cents. The 272's are a great all around cam for the dsm's. They make great mid range and upper range power with out much noticeable low end lose. Not that anyone thats considering a 3065 would really care about the very low end. I would recommend the 272 / 272 combo to you. As for the dual springs, I didn't know BC made duals. I know they make single (#BC-1100) and they are rated to go upwards of 8500 rpm. I'd say unless your plan on serious taking your motor over 8500, constantly, that they single springs would be a perfect match. Dual springs are for people with F1 engine sounds stuck in there mind! Another good thing about the BC single springs is that they work with the standard valve seals. No need to replace the seals if they're not bad. Dual springs (everyone I've seen) require a smaller dia. valve seal with means more money.

Anyone else have any opinions. I know everyone hear has something to say about everything. Lets hear them.

My bad, no duals, singles, upgraded singles. Thank you for that correction.

Stock head and 272s are safe till 8k. Are you trying to rev past that with a evo3....Well you shouldnt be.

 

[outkastracing]

just got my bc spring kit and i love it its about half the weight of the stock ones im really excited to use them and just my .02 its a good piece of mind when you do hammer down

I just got my BC 272s in the mail today. I also got the BC springs. Id rather be safe than sorry. Plus its easier to do it all now than to rip into the head again in a year.

^^^Man everyone is very quick to jump the gun lately. No, i rev to about 6000-6500 now. Later, i would like to though when i get the bigger turbo. So, the springs would be a good decision?

Trent, you not working at home depot anymore, i havent seen your car in a while? Take a video after you install those, or let me meet up with you one day to see them!!

James

 

[T Money]

Yea Im still there. The car has been down for a month or so. Should be running again in a week or two. Ill let you know when there in.

 

[VETTE_50_TH]

Cool. Anyone else have BC 272's with upgraded springs?

James

 

[Black_Bullet]

I have BC 272s without springs... There not installed yet, i can probably give a review in a week or two.

 

[FullthrottleGST]

you've been given more than enough info to make an informative decision man. like everyone says, unless your planning to rev past 8k and to the moon then you should be ok. but having the upgraded springs wouldn't hurt.

 

[VETTE_50_TH]

Cool Black_Bullet. Thanks for all the input everyone, im going to go ahead and buy the 272 with the BC01100 springs. Should be good.

James

If you're on a budget... skip 'em. Not required, but if you can afford them, why not? You would probably just upgrade them later.

So good choice!

 

[fwdeclipse]

I have the cams minus the springs and so far I like them alot. I did notice a bit of a spool difference probably 200rpm in spool on a 20g.

 

[90laserRSfwd]

What did you end up deciding?

 

[Black_Bullet]

So does your car feel a lot weaker down low,(sub 5000rpms)
or is it nothing noticeable enough to complain about.
That was my only conflicting decieding factor about getting the 272s is not wanting to loose too much down low.

We put the BC0101's in my buddy's '95 Talon TSi running a TD05H 20G last summer. We used installed them with no spring upgrades on a stock 2G 7-bolt with 135k on it, 180psi across the deck.

If you're looking for something to make your turbo spool quick on the street or for autocross, I do NOT recommend these cams. While driving along on the street in 4th gear at 3000ish, with the stock cams if you just push the pedal to the floor the turbo would just come to life instantly. With the 272's, it almost feels like a non-turbo car when off-boost....it requires a decent amount of time to get the turbo into boost without a downshift. The BC0101's will add lag to ANY turbo.

On the flipside, the TD05H 20G would flatten out on top at around 5500-6000 with the stock cams....just like a 16G. With the 272's and NO other mods, the car came to life all the way to redline....enough to add almost 4 mph to his 1320 passes (107-108 to 111-112 at the end of a run.) We've since changed the turbo to an FP Green at the end of last season and haven't made a single pass since.

As far as tuning goes, not much was changed other than some fine-tuning up top to take advantage of the increased airflow. If anything, the bigger cams lowered EGT's and we were able to tune leaner. We did have to add a decent amount of fuel down low to get the car to idle....especially when cold.


Long story short....If you're willing to trade off-boost torque for some major power gains on top, they're worth every penny. Added a VERY aggressive idle to his car, too!

^^ agreed, I have the BC272's and an ebay 16g. It seems like it wont spool under 3.5k much. But the boost comes on almost instantly past that and pulls it all the way to 7500rpm.

So correct me if I'm wrong here, but what your saying is that with the 272's, no other upgrades, it took longer for the boost to come on then it did with the stock cams? Interesting you say that because I had a similar problem when I first installed my 280's. I did the same thing that you stated when I first tuned the car, added fuel down low. However, after leaning the car out before the boost came on, It felt like the boost came on earlier and with a lot stronger then before. I'm not saying your wrong or anything like that at all, I'm just adding my personal experience with the with 2 different tune...
