Take a look at the AMS Dyno Charts showing the comparisons of each cam. I am on the stock 05 8 turbo (10.5 hotside) running HKS 272's and love them. The midrange torque comes on so hard, it feels great.

However, once I upgrade to the FP Red, I will be doing Kelford 272's

 

Im currently running Kelfords, and to be honest. Im over them. I believe there are better cam's out there. Especially for my setup.

Im getting some custom cams made up.

 

My car made approx. 25WHP more over the HKS's. Tourque was about the same. (It was 95* with 95% humidity the day of the dyno) I am sure on a cooler day we would have had better results.

 

i like the 272

 

Anyone else?

 

I think it would be difficult to find your exact gain until you make the switch. I went from stock 03 turbo with stock cams to GSC S2's, and by redline I saw a difference of approx 60whp. To me HKS 272's are a waste but I am someone that wants all the power you can get...

 

I run the hks 272's and make the same power as a friends kelford 272 car... he also has a br deluxe fmic, ported 9 turbo, 02 housing, and a cutout... im still on stock fmic and untouched 10.5 hotside 8 turbo. Both on e85...

 

Sounds good Any difference in spoolup?

 

what cam timing?
