Millers 'CVL Turbo' Fuel additive
Turbo Mini Forums

Just popped out to get some Millers CVL for weekend. It appears that Millers no longer make CVL and have replaced it with CVL Turbo.

The new additive now increaces the octane by 4 points, so running Optimax with CVL Turbo should give 102 octane, nice.

Not cheap though, ?7.50 for a bottle that treats 20 litres.

Still, more octane = more boost = more power and as your pockets will be emptier this should help you go faster still.

so full fat 4* + millers gives 104 octane ,mmm nice

Everyone knows that instructions only have to be read if the thing doesn't work....

Becareful...

four points can mean 4 points of a percent!!

Its all in the marketing spin!

100 + 4% = ........

Optimax is only about 98-99

Millers quote on thir web site that if you add CVL Turbo to Optimax you will get 102 octane.

Optimax is 98

£7.50 for 20 litres?!

OUCH!

any how many laps / runs is that up the 1/4 mile?

not alot, good valve if you ask me!

With Optimax at its current price, a litre of 102 octane fuel using CVL Turbo works out around £1.30/ litre.

My car does about 1mile/ litre when racing so it still is a bit costly.

Got a couple of bottles of the normal cvl from merlin motorsport and if thats anything to go by the new turbo additive should be the tits. Felt like it pulled better at the top end with the cvl added (1 bottle to 3/4 tank) would be nice to check out gains on the rollers!!

If any of you can get hold of toluene you can use that as an octane booster. I used to be able to get hold of it for about 60pence a litre. A lot of whats in octane boosters and indeed super unleaded is toluene and benzene.

I tried some millers octane booster on the rolling road, power run before and power run after, and there wasn't any difference in power, however that's not to say it doesn't help things, either. I did give it a few mins to get round the system, but maybe it needed more time.

If you have an engine that runs well without octane boost you will NO gains in power, why would you ? The only time you will see it improve output is if it stops detonation.

Well I thought the better the octane of the fuel the better the burn and the result will be a saver burn for the engine and being higher octane a little more power as well, why else do people say there cars feel better with it, even when there cars run ok on lower octane's.

because they are wrong matt!

unless you set up an engine to make use to the improved octan no difference will be seen on a dyno, RR or on the road!

To be honest you will find on many boosters that back to back tests will give less power when running the octane boost as the calorific value of the additives is often lower than that of the srtandard fuel you add it to.

250ml of additive in 20,000 of petrol isnt going to noticable effect the calorific value is it?

Alex

By the same argument it wont make any differance to octane value then. No not big difference, but just making a point about what it is people are adding to the fuel.

all i use the stuff for is to save me having to get an unleaded head at the moment. :)

But the additives are where the Octane comes from...

pure hydrocarbon chains are very simple...

I don't think I could run the boost that I do without an additive, and CVL does a fine job. I have had the car set-up with an Optimax/CVL mix and I suspect that the car would perform worse now without it.

Some injection systems might have the ability to cope with the higher octane fuel and therefore improve power with them added. I know for a fact that my Subaru dosen't have this ability and 'feels' slower when I run 98RON rather than 95RON.

I think that makes sense?

They sure do Wil, your car retards the timing when it sences knock...

REtarding your timing seriously harms your power!

"pure hydrocarbon chains are very simple... "

So you're a scientist as well as a motor technician???

stu ??

Everyone knows that instructions only have to be read if the thing doesn't work....

lol

I know some chemistry...

petrol hydrocarbons chains are 6 to 12 carbon atoms, combined with hydrogen of course.

like I said simple, sadly thats not all there is to petrol and thats where it gets complicated!!
