I know for sure most people will tell me not to do it but I have heard a lot on both sides. Obviously raising boost is better than raising static compression and I understand that part. I have an engine ready for boost but the compression is quite high (12.5:1 pistons!). I want to boost the car and put like 5 pounds on it in its current state and stay on 93 octane but I am not looking to gain the most hp (which I would be consider pushing the limits of any configuration) from the configuration. I have heard that you can boost with 12.5 cr although it is not recommended ( I fully understand that). My engine is dohc so I know that valve timing can be played with more. Does this also mean that the intake cam can be retarded to effectively reduce the static compression while not sacrificing exhaust timing? I eventually want to reduce the compression of my pistons. So if I am not going for the full power of my build (Tuning to get the most of out the engine) could it be done more reliably?

 

Instead of going through all that, and analyze every part of this series of vague questioning, let me offer an "olive branch", by showing an example of a setup that's done what you propose. you can then contact the OP about those changes.

I wouldn't personally go 12.5-1 with straight 93 octane. E85 or methanol injection is a different story. Add methanol injection or go with e85 and you're good to go.

 

I understand that I could go e85 or meth injection but e85 basically doesn't exist where I am else I wouldn't question it and go with e85.

 

You don't have to go E85, but you do need to have better knock resistant fuel (Or fuel additives) to work properly. So, Methanol injection or C16 it is. But it won't matter if the wrong turbocharger is chosen for the purpose needed.
