I am getting ready to go the 3.4L stroker route with my MKIV and wanted to get some feedback on other's experiences with them so far. My key question is what compression ratio people decided to go with and what their results were in terms of responsiveness on the street. I believe the "standard" BC kit that MVP stocks has an 8.5:1 CR, I don't know the CR details on the other stroker kits, but obviously custom CRs are available.
I would be mating the 3.4L to an Obiwan built/ported/polished head, going for a leftward heavy power curve by re-using my BL 67DBB (at least at first), running on pump (93) and meth at a low-ish boost (±20 psi), and tuned on the AEM. I am not too worried about the turbo running out of breath on this motor, my goal is not big dyno numbers.
I know that alpha6164 built his BC 3.4L with a 9:1 CR, but sadly I don't think he is going to be able to give any feedback for a while due to his motor problems. Anyone else built their stroker with a higher CR that can speak to the real world benefits/drawbacks they have experienced? Thanks in advance for any info!
