Horse power on removed vaccum line (stage 1) engine.

What you guys think the gain in hp when you remove all the vaccum emission crap? I did the stage 1 and I'm curious, I definily have more power now. Couple that with my new motor and I'm all smiles.

Technically you're not 'gaining' any horsepower, you're just making it more readlily available. Vac removal is just unwrapping the De-tuning they did to make the car sellable in the US, and to make it run perfectly stable under all conditions.
I would take a guess you have somewhere between 8-18 more HP available by de-tuning the de-tune.

More like 3hp. It will just make the carb run better. And seriously, stop starting new threads when this has already been discussed to death. Search is your friend.
