Wasted monies in my opinion... ;) Frank Title: Re: Race fuel upgrade ? Post by: danny714 on December 16, 2007, 17:33:49 pm ok , thanks , may be upping the cr to about 10.5/1 at a later date but not too long . Any suggestions would be great
Title: Re: Race fuel upgrade ? Post by: Udo on December 16, 2007, 17:59:25 pm It depends on what fuel you have . Super plus like in Germany (98) roz ron octane is good for 10,5 : 1 . 9.5 :1 95 octane

Any suggestions would be great Even with 10.5 CR, Race Fuel does not make sence... ::) If you want to use Race Fuel, get the CR up to 12.5 and use VP C-12... Frank Title: Re: Race fuel upgrade ? Post by: danny714 on December 17, 2007, 21:06:28 pm Thanks for that guys , got plenty to think about now . Why would race fuel make it slower ?
Title: Re: Race fuel upgrade ? Post by: redbluebug on December 18, 2007, 01:37:04 am Burns too slow. ;)
Title: Re: Race fuel upgrade ? Post by: Bruce on December 18, 2007, 04:52:53 am . Why would race fuel make it slower ? It releases less energy during combustion. In a high CR engine, the higher efficiency makes up for the lower heat of combustion such that the overall hp is more.Title: Re: Race fuel upgrade ?
