NOS Octane Boost Formula - Race

[tvr5000]

Any good? Will it work with cats? Costs 19.99 from Halfords. Theres a cheaper version NOS Octane Boost Formula - Street at a tenner. Anyone used them before?

[bogie]

yeah - Ive used it before on my Elise (has a non-std Honda engine and is mapped for 98RON) ...I carry some around on long journeys abroad just in case I cant get 98RON

I dont think it will give you any more power, unless your engine is mapped for it or you have a knock sensor

[Hoover.]

I've used it on tunnel runs to aid with my car spitting flames out of the exhaust........

Not sure of the benifits.... and yes my car was running v rich at the time with a big split in the pipes
