[QUOTE="Doug, post: 12754031, member: 8576"] Alright, I feel like I should know the answer to this question, but I haven't had the time to really research it. [B]Synopsis: [/B]I've got a stroked motor, flat top pistons, milled heads, stock cams, lightly ported b heads and none of the usual bolt ons (no ud pullies, stock coils, fms wires, full weight...) Compression Ratio is 11.33:1. Makes decent power - 291hp/292ft/lbs on a Mustang Dyno. The motor was originally intended for around 250 - 300 hp worth of nitrous. I no longer want to go the nitrous route. While I'm still an advocate of it, it is just not something I want to pursue any more. So, I'd like to jump on the bandwagon and put a turbo to it. [B]The Dilema: [/B]My question is with 11.33:1 CR and the fuel around here either straight 93 or "up to 10%" eth blend, would it even be worth it? I haven't a clue what would be acceptable boost levels to run on the car at 11.33:1. I would think 6-8 would be a good starting point, keeping timing in mind. Also, if that's too much compression - how would getting thicker head gaskets hold up? I need some opinions cause the googling isn't being much of a help for my specific questions. [/QUOTE]
