Bc 280s Cams! Need Answer.
how about some info on your plan and mods before i throw out a suggestion on spec to go with...
if you are set on running the BC 280s i would suggest running springs. with a .050" of 220 @ the Cam those are some agressive cams and you wouldn't be getting the full potential of the cam without upgraded springs.

My personal suggestion in this order: GSC S2 (nothing less if you are after max power), Kelford, FP, Cosworth. The HKS dont make as much power and cost 100 bux or more than either of these for a set. The BCs just plain dont work and the springs have a limited lifespan as well. I managed to get 12k out of a set that now valve float above 7k pretty severe (think drop 80whp and you got it). Valvesprings I would go with FPs for 9200 and down, and Kiggly's for 9200 and up.
I stand by my statement. They are junk. You made some more power with them but that doesnt mean they are the best. You picked up 9hp with 3psi less boost. What is the back to back though? I have seen BC280s make very little power at the same boost level with no other changes. Anything less than a back to back is pointless because we dont have a percentage of increase. I have seen some stock cam VIIIs pick up almost 9% with a good cam change.
For what they are a set of HKS272s could have done that. Please recall what I do for a living and when I make a statement it is never done lightly. BC has horrible quality control, the lobecenters are extremely tight, and for best power you need cam gears with them. A properly designed cam doesnt have to have 3 hours Fing on the dyno to get them dialed. The IX cams are even worse and I have seen them straight lose power over stock. Have you ever looked at the measurements of these cams compared to stock vs their competitors?
280 sounds big but they are a rough idling S1/Kelford B/Cosworth 264 and little more.

This is from AMS test they did.
HKS 272
base- 418hp
hks272 - 456hp
Gain is only 9% cost of these cams is around $640.00 per set
so you are paying $17.07 per 1 hp on these cams which you say are better then bc280
BC280
Base- 418hp
bc280-452hp
Gain on these cams is 8.5% and cost is $350 per set.
So you are paying $10.29 per 1 hp pn these cams.
So tell me why these are junk again, if you say bc280s are junk then hks272 are even worse, you pay more money per hp and yet get same gain out of them.
I dont like when people start bashing other peoples product, you would under stand if you would ever build your own cams and then listen to other people bash them and say they junk. These cams are half of price then any other cams on the market so no one will tell you that they will be better then others.
All you had to say is , if you want more power out of your cams get the gsc s3 or etc,,, not saying bc are junk cams. Not everybody here have the money right now to pay $700 on cams plus $250 for the install while you can get bc cams installed for the price of hks cams alone.
JohnBradley I dont mean to be rude to you and your work but everybody got there own opinions and im sure you would feel the same way if some one was saying your work or your product is junk.

That test was done on properly degreed cams. I am not arguing with the results but unless thats being done on every install to make sure that the cams (which have QC of 1 every 1000) are being ground correctly you cant say that the BCs always provide the gains they should. I would say you are the exception to the rule in general.
As far as being rude and all that, I am not doing much better. However not caring is what you said and what I do is because I care and want to make sure that everyone spends their money correctly. My personal experience and based on just the engineering that BC provides these cams are still less than optimal.
For budget that doesnt break the bank the Comp 272 and FP4R are only $100 more than the BC and a superior product.

lol, first off hks 272 dont cost the same as bc280 so dont give me that bull ****, second, i dont care what you do for living or who you are but im telling you my bc 280 made good power and they dont lose hp on evo 8s, i hear they do on evo 9 but so far no DYNO sheet to prove of lost power, and i guess when i get my cam gears installed i will even make more power on these cams. These are not the best cams in the world no one is saying that but to come out and say they are junk, dont make power at all, i guess me and other evo owners who made good power on them are wrong, and i guess amt test is not true showing power gain on stock cams????? Trust me your not the first vendor on here to bash a product that you think is junk.
Its good to see you make power, but remember they had those in Paul's car and pulled them out in favor of GSCs. There might be a reason I'd think they did that.
