In Reply to: Any opinions on "octane boost" formulas out there? posted by John D. on March 02, 2001 at 08:12:20:
On the track, backing off my timing is very noticeable on long straights where I may be under full boost conditions for extended periods. At these times octane booster had made up the difference. It will only raise you up a few points from as little as 0.1 to as high as 1 depending on the "mix" and how much you use.
It can be hard on catalytic converters and it makes my car flat stink after a long track day. For a non-modified car I don't think it will do anything for you. If you are running higher compression or a high level of boost in a positive induction system you may need it (or better yet buy racing fuel).
It has its uses but in general I don't believe most people out there need it.
