Alright so I'm shooting for a pretty high boost build and so I got to thinking about how I could lower my compression right? So I did some reading and found out about boring the block and such, but unfortunately I cannot afford such things, so I took my own DIY approach! Pics attached



I figured, adding extra grooves and such would increase surface area, lowering compression. How do y'all think I did? How much psis do you think I can run with this engine?

 

all of it. max it out and video it so we can watch

 

I think you may have already run them all.

 

I've had the crowns of pistons fly cut to reduce the compression ratio. Do all the things. Just don't do rods.
