How much HP do you get when you take an ls2 434 at 15-1 and spray 500 to it?

Iron and rocked is the way to go 
I think I know some one with that combo 
You **** is going to rock Dog I will probably only get as good as your N/A numbers

The ls1 is a great motor, just the alluminum block has it's limits and i reached them remember this is a race motor max effort!
I think you definitely reached the limits of sleeved block. Hell 15:1 is enough cylinder pressure as is. I am going to be doing a dual stage progressive setup this year. I am trying to spray around 400 onto an aluminum block. I'll only be around 11.5:1 but we'll see how it goes. I think the progressive nature will really help control the hit.Nate

Your right at 15-1 there is a alot of cylinder pressure. My first concern was lifting heads, but that wasn't even close to the problem. To make shure this doesn't happen again the new iron will be block filled about halfway. W to W just built a 1700 hp iron twin turbo, So it can be done, just have to wait and see.
