Millers CVL Octane booster is about the best out there - http://www.merlinmotorsport.co.uk/product_info.php?products_id=5894?utm_source=Google&utm_medium=Shopping Does work - Hurdy's probably the person to interject here as I know he's run a few bottles of it through his tank in the past.

Dom, as Dom has pointed out, the Millers stuff is the one of the best out there..

I've used it loads of times on my old mk4 Ibiza Cupra (also used it in the Eddy when we were at Motoscope) with amazing results.

Reduces CF's and allowes you to add more timing  :happy2:

Yes, the Miller's CVL Turbo Octane booster is the stuff you want. I did comparative Dyno's using this stuff and it gave me another 12.5bhp, so it definitely works.

You need to add two 500ml bottles per full tank.  Make sure you fill the tank to half , then add the bottles and then carry on filling the tank. :happy2:

That sounds good :happy2: going to have to give this stuff a try. Haven't got high hopes for the power off this new map so millers might help to give it a gentle push :laugh: the map hasn't been on a car that's been dyno'd so will be interesting to see what it makes in a couple of weeks.
Thanks for the info folks :wink:

The best octane booster without doubt is NF Octane Booster. The Millers one is not very good.

Can you actually feel the difference when its used? Or is it more of a thing that's seen on paper?

There's nothing wrong with the Millers stuff, I have seen good results from it as has lots of others that I know..

More of a thing on paper realy. But you should feel the car run a little smoother though  :smiley:

shouldn't see octane booster as performance enhancing..i treat it as a engine blow up preventer when ragging the car in certain conditions (detonation prevention)   :happy2:

example is on track day but no V Power around only 97 SUL so i take some OB with me to bump up the SUL to what my car is mapped to etc.

i've run Millers CVL Turbo with Vpower on Revo 100+ with no issues, 2x500ml is best part of £20 though

From the Millers website

18. Which additive should I use to get maximum performance from my car?
Millers CVL Turbo will add 4 octane to the base fuel. This means that up to 103 octane is available by using Shell V Power or a similar premium unleaded fuel. This combination is ideal for Motorsport or track day use in all performance engines.

19. Is it OK to use CVL Turbo in a car fitted with a catalytic converter?
Yes, no problem for track day and occasional road use, but is not recommended for continuous use. We have a product called Petrol Power ECOMAX (which adds up to 2 octane numbers) which is suitable for continuous use in vehicles fitted with a catalyst..

does that mean another map then Dom :smiley:

No mate, last map I'm ever getting! I'm suprised hedge didnt get that comment in before you!
As long as it makes over 315bhp I'll be happy, as thats all I got with Bluefin stage 3 with the straps tight on the RR. The Revo stage 2+ and PDT  map were all loosely strapped down, so probably only realistically made 310bhp and 330bhp respectively on my car. It drives well, has excellent power delivery regardless of what it makes on the day so I'm happy with it.
I'll just buy one bottle of millers CVL and stick it in half a tank of fuel, just incase I cant get hold of any Vpower on the day :wink:
