BC 280's have issues and Ray Rocks!

You are thinking wrong. BC cams are fixed now.

You are thinking wrong. BC cams are fixed now.

Obviously
oohnoo's question was about other performance cams. Is there any benefit of the new BC over other cams. But IIRC this thread or the other one on 3si pointed out that all aftermarket cams for our cars have this issue. BC is just the only company to fix it.

I don't know if regrind cams have this issue since no one really tested them, but I think not having to run shims on BC cams is a good enough reason for me to buy blank cams.

i have a set of DR street regrinds that are not ground wrong

[oohnoo]

That's good to hear as I have those on my car

So the BC stage2 are regrinds, and 2+ and up are from blanks?

Also, has the ,fix been applied to all of their cams?

[mehrshadvr4]

yes. Ray has the new 262 IPO has the 272s and I have the 280s.

We have the new style BC 272s in Courtney's car. I may do the new BC 264s in my car. Time to get more top end.

Ninja Performance Customer build/tune. Still have some boost left in her (turbos are good for at least 34psi).

Dyno graph shows 20psi but is really 24psi, this is due to the AEM data reading boost lower than it really is (all taken into account in the fuel and ignition maps)

Will probably get her to around 28psi max to allow for some reliability. And obviously from the graph, pull more fuel up top. E85 likes 11.8-12.0 (leaning on 12.0). But this is a good start.

Looking good! Hope Courtney finally gets to enjoy his car.

Chris, I think you will see big gains from an intake mani. Here is a supra comparison on stock cams, big turb/low boost.....


Any losses should end up below where yours or Courtney's turbos would be moving air anyway. Running your car out to 8k+ is well beyond what our ridiculously long runner and small plenum mani's are designed for. By the time your turbos spool up, the intake harmonics are not playing nice. Just think what cams would do on top of it

It's a much different feeling driving a car with power that climbs to the limiter, compared to falling off a cliff.
