Re: How to increase HP
There are always the obvious ways to increase horsepower, Such as use higher octane gas, oil change, filter/fluid changes. Change your exaust, put cleaners in your oil, add supercharger, turbo, so on so forth.
Best thing for a car that old is leave it alone. At 150+ miles you can cause alot of problems by trying to do stuff. Dirt and grime can cover leaks of any sort and putting cleaners/perfomance fuel that burns hotter can open these leaks up and cause alot of problems. Even your break line can start acting up.
The main thing i would suggest is modify it to have a higher starting RMP (tighten the acceleration wire, or whatever its called) that way you have a higher RMP to start with and can accelerate to higher speeds a little faster. It will use more gas though.
