Message: [QUOTE="superpsd, post: 1399545, member: 15821"] Engine is completely stock. No studs. No springs. 300K miles. Never done a compression check. Mechanical fuel pump with a spin on filter and aeromotive regulator. I have been running the supercharger for 2 years now back to when I had stock injectors. I do have a haze at idle so light that I can only visibly see it on bright blinding sunny days. My timing is untouched from the PHP canned performance tune. Idle is set to the factory 650 although I did build a tune that is the same as my daily but bumped the idle 100 rpm higher for when and if I get stuck in traffic jams to make it easier on working the ceramic clutch easing thru traffic. I also built B code injectors which have the 3600 VOP springs which may account for a cleaner burn. The injectors are split shots that I took and TIG welded the spill port shut. Injectors were old cores that have never been flow tested. I had to grind the back of two of the armatures to allow the injectors to light off cold as they have worn poppet valve seats. They run well and feel balanced wish I will put that all on being lucky and not my injector building skills. I think it was Charles on here who said they played around with different VOP and found that overall the higher VOP made for a cleaner burn but power had dropped up top. My idle pressure may help a little I would have to remove the belt and start it up and see. [/QUOTE]
