I had asked a question a while back about which fuel to use and I was told C12 or C14. Now I noticed recently more people are being recommended to use CMP. Is this a fuel I should consider??

Engine setup:

Naturally aspirated 347 SBF
Cylinder Heads: AFR 205cc (Milled to 55cc Chambers)
Vacuum Pump: Moroso 3 vane (~14 inches of vacuum)
Compression: ~13.75 - 14:1 C/R
Shift: ~ 7500
3000# race weight

If you want to run an oxygenated fuel, then CMP would be a great choice. It should give you 3 to 5 hundredths in the quarter over C12.

Are there any pros or con to running an oxygenated fuel?

[Pooch565]

Pro's it makes more power. Cons it costs more. Thats about it.

At what compression ratio would it be advised to go from CMP to DRT?

[Pooch565]

It depends on CR, cubic inch and RPM. I would say to be safe, in a small block and high rpm, 8500 or so, 14 to 1 or higher go to DRT. If you were at 7500rpm I would say CMP. If you are a big block and 7500rpm, I'd say 13 to 1 or so go to DRT. Let me know if there is anything else you need.

Thanks,
Jason
