Tom, I too have done some research and your findings are identical with what I am finding as well. Depending on what is said about my question above, I may be switching over to the FP4R. I am going green on the SE with an AEM, so I have been watching you and your son like hawks lately...

+1 on the Cossie 272's.

I'm on these cams as well with stock springs. I find that my boost 'bleeds down' after 7300rpm about 5psi on every log. I'm wondering if valve float is the issue here. According to all of you cam experts, can springs be the cause of this.

If that's the case, I may just swap the cams for better units while I'm at it.

Anyone prefer these Kelfords or BR272's over a pair of Cossie 272's on a stock motor, AEM EMS, 35r car?

This is weird.
I asked: Question: Do the camshafts require a valve train upgrade?

They replied: Jonathan.If you are using more than the stock RPM and more than 21lb boost, werecommend a valve spring upgrade. Either Supertech dual springs or Kiggleybeehive or Ferrea beehive springs are the best option. ThanksKevin

What gets me is the more than 21psi, most everybody not stock probably runs over 21psi.

Yes, these will run on the stock spring and retainer, your rpm will be
restricted by the turbo well before it is restricted by the valve spring.

Thanks

I've actually just had the kelford 272's put into my car by AMS I'm pretty happy with them so far, lost a little on the bottom end, but gain a lot on the top end

Have you got a dyno graph that can show how much of a loss you had in the bottom end at all? Thanks mate.

Cheers Steve

If I'm not mistaken, that test was done exclusively with an Evo 8, therefor the results do not apply to us except to say that kelford makes good cams in general . As far as their mivec cams, I haven't seen a ton of data, but it seems promising.
