[QUOTE="blownstang4.6, post: 16307633, member: 129006"] They can, but the weakest link of the cobra rotating assembly are the pistons. Piston to wall clearance is small and ringlands aren't too thick. You might have a little more clearance than a factory motor. Guys on E85 run 22-24psi and it takes it. The biggest gripe about the shortblocks are the pistons and that's what usually goes first. As long as the tune is spot on and there are no meth/fuel delivery issues it should survive. Almost any off the shelf piston with a thick ringland is better than the stock Mahle pistons if you really want to give it 24+psi full time. [/QUOTE]
