Anyone ever run Alky and Xylene?

[Turbojorge]

Each coming from their own tanks ofcoarse. (alky from tank in engine compartment and Xylene from gas mix in gastank as usual)

Would their be any downsides or dangers in doing this?

A 3:1 xylene mix would put you at about 99.5 octane and the alky should put you above 108 or so. This would be about the closes to race gas without having to change 02 sensors every 20 miles.

It will be fine, same as running 100 unleaded and alcohol

That's pretty much the way I race my car.

A bit of 94 a bit of 100 and a lot of alky.

24psi. and about 24* timing on the WE4.

I'd dump a can or two of xylene in the tank sometimes when I'd take it to the track.
