CorkSport Camshafts, Yes they really exist, unlike Bigfoot!

[CorkSport - Derrick]

Yes we really have brought back the camshafts!


Have questions about them? Post away!

I don't believe you...

Lift, duration specs plz.
Also, how are they manufactured, including what kind of surface treatment/hardening procedures have they undergone.

Fine, dont click on the picture which takes you to the link and gives you the specs....

Intake .390" Total Lift 215.8 @ .050 Duration, Exhaust .354" Total Lift 204.2 @ .050 Duration.

The camshafts are induction heat treated with a rockwell c hardness of 50-60. We had the hardness verified by an independant lab. There is break in coating on the lobes we well to keep it easy.

No video of engine running with the camshafts?

They sounds just like an OEM cams really. If it had any kind of lope we would have posted that up.

How long and how many miles have been tested on these new ones?

7 months, 2 cars and I will have to chase down the engineers to get mileage information.

I must say I disagree with the statement that Bigfoot doesn't exist...

crapatalk, yes it sucks for free.

I clicked the pic. It didn't take me anywhere. 50-60Rc? That's a wide range. What is the material type, out of curiosity? 41/4340?

Any luck with that mileage info?

Or use mobile browser like Chrome. MSO is very mobile friendly.

What rpm are the test mules testing these at? How will they handle 7500 rpm with 65lb springs?

I am guessing you did not click on the link and look at the dyno sheet. Here you go.

We have not tested them with 75lb springs. The idea of the camshafts was to be a drop in set which did not require taking the motor apart to install.

Pshhh who takes a motor apart to install valve springs, just fill the cylinder up with air so the valves dont drop

So none of your test cars have gone full retard with a big turbo and beefed up valvetrain?

Thats what I meant

 

[CorkSport - Derrick]

Shortly on the full retard big turbo. Nothing with the upgraded valve train.

 

[Redline]

So, I'm sure the question on everyone's mind is if they pass the @Enki math test? Having said, these were designed by actual engineers with formal training in valvetrain physics, correct? Publishing the specs first is necessary, I suppose. I thought I saw them somewhere...
