    Apols for cross-post

    In preparation for the Knockhill track day have got a can of Pro-Boost. Normally use Millers, but thought I'd give it a go, as had been told it is 'better', and fancied trying it out.

    HOWEVER - have since been told it causes engines to overheat when using a full can (1 litre). Any views or experiences? best just to use half a can?

    Car is a MY99 with PPP set to 98 RON + downpipe, midpipe, i/kit.

    Thanks

    I used Pro Boost for thousands of miles of trouble free motoring

    When my engine blew up 600 miles after my Power Engineering remap, David Power drew attention to the orange colouring of my turbo and down pipe.

    Pete Croney says the orange colour is not an issue.

    This is the first I have heard of the issue.
    Where did you get the information from?

    All the boosters generate this orange colour as far as I know, you should see the plugs after even just one application. Its a normal side effect of using it.

    Thanks Anders, got info from Scoobynet! hence keen to get a more 'technical' opinion!

    How much of the can do you use as the measurements on the side of the tin seem a little vague. Was planning on half the can for almost full tank??

    Gary,

    Use the whole can for a full tank of fuel.
    Especially if you're out on the track!

    Thanks - but even on a UK car when I only need a 1 octane point increase? Happy to do it, but don't want to over stress/heat the engine. Not that I'm paranoid or anything....

    Don't worry about overheating the engine, the octane booster is hardly likely to do that! It will allow you to run more advance and hence the cylinder head temperature may be slightly higher, but it's either that or higher exhaust port temp due to retarded ignition, or engine damage due to det... take your pick

    Cheers,

    Pat.

    Cool

    I would generally put in 50L in my 60L tank filling it to the brim. Actually 49L as I would put 1L proboost in first.

    Helps with the "rally sound"!

    Now I have a stock of Millers as the bottles are easier to pour in

    Flames? Should be getting some of those if I can just get this wee module working before the next track day

    Cheers,

    Are you as hungover as I am?

    Cool

    To Clarify I normally fill up when the empty light has been on for a brief period of time.
    This allows on average 50L of fuel to be placed into the car filling it to the brim!

    Running the tank lower leads to fuel starvation arround corners!
