Well I've been thinking since I've been having a bit of trouble finding a tuner, I was thinking of pulling everything off again and adding cams and porting heads on top of my KB2.2 supercharger. What should I expect.
It's hard to get numbers because people always do more than just port the heads at the same time. So how much HP came from the ported heads and how much came from the other mods is guess work.
However I found a local KC guy here that got his heads ported. Says that's all he did, pull the heads, port them and put back. It was a twin screw car marking around 800 whp after the port. He claims the head port picked up 80 whp. Seemed like a lot to me but others seem to support those claims. I honestly have no idea how true or far off it is.
Malcolm, do you know did the guy repulley to make the same boost? Some guys like to repulley to make the same boost after some mods which obviously isn't an apples to apples comparison at that point.

What blower was he on? I gained a ton of hp just swapping from the 2.2L to the 2.8L.
I don't recall. I can see a 2.2 to 2.8 been a huge gain My Eaton to 2.9 Whipple was pretty big gain too lol.
