01 c70 convertible. Had it a couple years. Always thought it to be a 2.4 lpt. It's not. It's a 2.3. automatic. Sooo, glad got that squared.....that said, it's my first volvo, and I'm hooked. 163+++ mi, runs great. Learning to swear on Swedish as I put struts, ball joints, etc and timing belt svc, fuel filter, pcv,etc. Got car sorted, took test rip.....to 130. Cut out at 130. Is it limited?is it the 136+/-hp motor? Lpt boosts about 5 psi. What's this hpt boost to? Is it speed limited cuz of soft top?
