Default CAM - Stick or Twist?

Hi All,

I’ve been running my stock LS1 engined Cobra for about 8 years with a Thunder Racing reverse split Cam (230/224, 111LSA). 2 years ago I fitted a ProCharger P1SC and it’s running well/a total hoot to drive!

My Slave Cylinder gave up today which means I will be pulling the engine out shortly (man maths is about to kick in)...

It feels like a good time to move from the N/A Cam into a Blower Cam, but my question is...should I? Will it make a noticeable difference? Is the current Cam strangling the engine or will any change only be marginal?

Any thoughts?

Thanks

Jim

PS, emissions not an issue for me.
PPS, 2000 LS1, LS1 intake & TB, 2.5” dual exhausts, SD60Lb inj, FMIC

Did I miss why replacing the slave requires pulling the engine??? Drop the trans swap the slave and bolt it back together. Your cam has 5 degrees of overlap, not terrible for a blower. Unless you literally have to tear the front cover stuff off for another reason j wouldn't touch the cam.

If your current cam gives you the driving style you like, power in the right places and idles how you like....there probably isnt a huge need to change it.

Thanks guys, if it’s only marginal I’ll leave it in place.

DDN - it’s a packaging thing ;-)

Sorry, didn't realize it was in a Cobra.

I'd change it to something with some more exhaust help. The engine has to be stacking up with that cam. I wouldn't be surprised if the current pulley combo didn't result in less boost due to some back pressure reduction.
