I own a 2010 cobalt lap f23 coupe. All my m62 parts should be here This week and I needed a to know the max bottom end power these Things can take. I’ll be on E50 (thats what our pump e85 tests out at &#128530. Thanks everyone!

 

Welcome to the page. You can safely make up to around 250hp all day. People may come in here an tell you that you can make more than that on stock bottom end, and you can, but you risk bending a rod the second something goes wrong.

 

Welcome!

 

Welcome!

 

Welcome, Looks almost identical to my ls except I got rims lol. Around 250 is safe to daily on a good tune. More and you better have parts set aside at the ready.

 

Welcome!
