Let's not forget the MON rating of the fuel.

If you do some digging, you will find quite a number of references to the MON being much more significant a rating for high boosting engines.

I have the spec sheet at home and can not post it up for you, but evo 400 if you are going to post information on the fuel, lets see all of the data including what temperatures the % of fuel boils off at, the specific gravity etc and make a more complete comparison to ELF and the other available unleaded racing fuels.

Please also give us the point of reference that backs up your statement that the Shell product destroys ELF Turbomax for power.

I have heard exactly the same thing straight from a few ppls mouths. Mark at MAD is setting up a few cars to run on it. On a certain car it is running 7degrees more advance over the Elf fuel. This is on a distributorless ignition system.

Maybe I should try it in the Nova;)

7 degrees more than Turbomax is an interesting statistic.

Being able to run more ignition may just mean that the fuel is slower burning which will be helpful to one engine but not much use for another.

Logic tells me that the higher you rev an engine the faster the fuel will need to burn to deliver it’s power in the cylinder rather than in the exhaust.

As you raise the boost, the more the fuel will spontaneously ignite, which then requires the octane to be raised which slows the rate of burn and opposes the needs of the high revving engine, so the balance must lie somewhere between the two.

Head design is not universal so a combustion chamber with lots of squish will have a different requirement to a hemi shape etc.

The oxygen content obviously delivers a bit of extra punch, most of the turbo unleaded fuels claim a 2% to 3% oxygen content, but make no mention of how available it is to burn.

Dyno sheets for a high boosted engine that was properly mapped on both fuels would take much of the sales oriented opinion out of your comments.

This is a really interesting topic, lets us have more facts, which will no doubt be helpful to your business if you can back up your statements.
