The BC cams are alot cheaper which will probably keep these cams from making a big showing on the dsm side. I am planning on using Kelford in my Evo. I use BC 272's in my Talon and they definitely wake up the top end, but the cam test numbers don't lie. From the searching I've done over at evom, everyone that uses Kelford seems to love them.

 

It's hard to buy anything other than FP these days.

 

FP has great products but a little pricey ( at least w/ turbos.) The only thing Ive ever purchased from them is their exhaust manifold...

I felt gains with the bc272s up top, down low wasnt too appealing though compared to my friends old 16g setup w/ fp2s.
I want my build to be of a little better quality and to not feel like I am always down on a good amount of power with every upcoming mod just because of the cams.
When I originally bought the BC cams I was just being like any other dsm'er getting a mod quick on a budget. Im taking my time on my current engine build, figured I do it right. Im just going to sell these bc's...

 

I just dynoed yesterday with the BCs, and from 5500 to 7500 RPM's power was flat. Let off at 7500, should of revved to 8 to see where the power was falling off. I was very impressed. Stock cammed the power went down the shitter after 6,000.

The Kelfords do seem like a very good choice though. Not enough real world testing out yet.

 

I plan on trying kelfords once i get funds this year.
But that is a lack of testing for dsms on it and a lot of people that want them already have springs and no-one can give a straight answer if they will work or not.

 

Thats why I made this thread. Need to see whats really up with them before dishing out any money. I didnt plan on starting my engine build for another couple months so I had a little time to gather info.
Id like to assume any quality 272 cam should be safe on the stock 4g head up to 8k as Ive seen 8k several times on these bc272s with no issues, and Ive seen 8500 on stock cams, stock head.
I personally planned to run brian crower springs and retainers in this new motor though and 8500 will be as high as Id want to rev it...

And the Brian Crowers arent bad cams when considering the price, I dont want to make it sound like anyone with these cams should think twice. I enjoy the cam lope and the power up top even on this 16g setup, but I do know that they could use degree'ing to get ideal results, and in some cases they NEED to be degreed. I wouldnt be surprised if mines are all off from me just dropping them straight in. And I dont find it worth it to spend money on quality cam gears and dyno time to get them right.

 

The BC 272's did not fair well at all on the EVO cam shootout.

 

I know the Lexus SC 400 1uzfe guys have been using kelfords for a while, let me see if anyone has any first hand experience with them.

 

I think something a LOT of people fail to look at and is rarely advertised is ramp rates. Just because the cams have the same degree does NOT mean they have the same max lift or ramp rate. IMO ramp rate is just as important as max lift. Imagen two cams that have the same duration but one has a sharp egg shaped peak and the other a much more rounded lobe. Wana guess which will make more power and which will be more streetable?

Anyone thought about GSC? I noticed in that shoot out they out did the HKS cams as well. Which are the ones I WAS planning on going with, now I am starting to think about them. I don't recall seeing much on the Kelfords though, bad memory I guess....i'll take another look at the shoot out's test results.

 

A few of my friends are running the GSC's in their Evo's... Make some insane power, but however, I don't think they make them from DSM's?

 

Yes, GSC does makes cams for us. I believe their listed as the EvoI-III cams (which is obviously the same as us )

 

I dont either ^ and I think the Kelford 272s still proved to be better.
Hell the kelford 272s beat the fp4r cams which is pretty damn good if you ask me.

I think its just a matter of time before more dsm'er's start branching away from the typical HKS, FP, and BC cam combos for this sized cam, unless those companies step up their game and come out with a revised or new product.

Though I still think that the FPX series cams are some of the best cams on the market for that size, FP does have some quality stuff.

The other thing I wanted to speak about is how different is the EVO head ( mivec ) and all in comparison to the old school dsm 4g? How much similarity should we really rely on from AMS testing on the evo motor?

 

I've had a wide variety of cams in the past couple of years: HKS 272, BC 272, BC 280, Comp 101400 (same as FP 4's), GSC S2, and now Kelford 272's. My favorite is the Kelford's, basically maintains the same insane top end as the BC280's, Comp 400's, and GSC S2's with better idle characteristics and mid-range torque. GSC's were great cams as well, can't go wrong with either one. Set up is on a 2.3L with a T4 T67 turbo, nearly all street driving.

 

So the Kelfords were just as good on the top end but better mid and low end compared to the GSC?

Any idea if they make 264's?

 

Be careful when comparing the BC cams for the Evo and the DSM. The info doesn't translate directly. If you are shopping for cams look at cam comparos done on DSM cams in a DSM. The Evo info is good reading but may be misleading if you are buying cams for an a DSM.

 

This is what I was originally assuming, but to say the least we know there is gains to be had with swapping bc272s to the kelford 272s. especially since all the bc cams tested desperately needed cam degreeing.
Now I dont know if theres any desireable gains in going from the bc280s to the kelford 272s as the bc280s didnt do as bad on that AMS cam testing.
BUT, there are Kelford 280s on the market

I have a friend with BC 280s in his car and were going to dyno it with his 60trim setup sometime soon. I told him whenever I order my kelford 272s I will let him drop them in his car and we can then dyno it with the kelfords in vs the bc280s and see what we come up with. The only reason Im letting him do this is because my motor wont be built yet at the arrival of the cams and Im going to be down for awhile.

 

So whos planning on running these cams besides me?

 

I am going to try a Kelford or GSC as soon as I get motived to take my FP2's out. Maybe I'll even do a back to back on the new local dyno

 

Soon we will be doing a back to back test on a 1g with an EMS in it.

As the car sits now it has a bolt on 35r with all supporting mods and BC 280's.

We will be doing a test pull with the 280's to get a base line then swapping cams out right on the dyno.

As soon as we have any kind of word on this I will let you guys know.


-Em

PLEASE DO!

Have the BC 280's currently in the car been degreed? And will the Kelfords going in be?

 

STM FTMFW!!!

Thank you guys for stepping up, everyone else has been useless until this point.

 

Everybody up to this point hasn't been useless. Do you have the funds for a back to back camshaft dyno compare?

 

^don't start shit. Another vendor has been trying to sell these cams and they have no info on what springs i could run i had to talk to kevin @ kelford himself.

I have called multiple shops only to be told "well its a 272 that is one of the best so you will make good power with them."

And finally I was part of a back to back dyno cam test last year on the link forums, luckily link isn't a open forum. Sadly its exploding. but those guys deserve it.

 

I just bought some kelford 272 for my fwd 1g... On stock cams the car made 355whp... I'll post the differences I get.. With sheets... EVO3 turbo..

 

Do you mind going into just a little more detail about your setup?
And yea post the differences when you get the kelfords in. If these really are such great 272s they need to be hyped up more so these kelford guys continue doing them for us dsmers, and possibly coming out with new and better cams in the future. I think Hks 272s and BC272s are played out and its great to have a new option available for the dsm market.

So to benefit my thread, what did Kevin from kelford tell you regarding the springs?

 

Anyone have anything else to say on these cams yet?

I convinced another dsmer over on Tuner's to go with these cams instead of picking up some bc280s. Seems they've been selling out on a couple sites, im sure some of you fuckers are running them already and just being quiet about them lol.

Funny you said this................... I was thinking the same thing.

Give it a bit more time. The weather is just beginning to break for a lot of the guys. Once they get tuned and hit the dynos/tracks, I'm sure we'll here more about them.

I'm still gonna keep my BC 272's in. I have them paired with adjustable cam gears all ready, so once I get things fired up and get a decent tune down, I'll start tweaking the cams a bit. I can't complain, I picked the BC's up BRAND NEW for $250- shipped. The cam gears are the Skunk2 Pro series 6 bolt adjustable ones. I got them for $150- shipped BRAND NEW. So I'm into it for $400- total........................... I honestly can't complain.

 

EVO guys are breaking these cams. Do a little research on EvoM and see the results. Apparently both Cosworth and Kelford use the same cores and both are having a lot of defective problems.

FWIW A local guy broke his cam into pieces and it fucked his motor up something nasty.

 

How the f does that happen.
Well ill check over on EvoM and see whats up.

 

^ +1. That is what I have read too.

 

I know these cams were tested (in a evo) against Tomei 280's and cranes 264/272 combo... They held their own...

They feel great in the fwd I just them in... Just put a new clutch/flywheel/ trans in so I'm takin it easy... But at 15psi, the car feels awesome...EVO3 16g.

 

When do you plan to hit the rollers with these cams?

 

I bought them a while ago, but having bad luck with everything. It took about 4wks to get them to my house. And I am having a problem getting my head back from the shop, that is why I still have not run them or even installed them, bc I don't have my head yet. Perhaps in 1 month I really hope so. When I do, I will post up info.

 

Honestly I'm kinda surprised they got labeled as 272s. Those are some square lobes.. Anyone look at the spec sheet? They're bigger then FP's 4r..

They look like great cams tho

 

You are right 272 is misleading, they are a big cam when compared to the other cams at .050. the 272 measurement is at .010 where the competition measures their cams as well. It's a meaningless number. .050 and up is where it matters. Unfortunately this is something 99% of cam buyers have trouble understanding. These are BIGGER cams than most 280s!

 

My next cam of choiace was going to be the FP2X's (currently running the FP1X's) but since these are no longer available I think I'm currently leaning towards the Kelfords. But that won't be hapening till atleast mid summer, so I'm not much help either
