Hello i am building a 438 with 12.5 comp ratio victor race heads


I would like to know for dyno purpose next week which fuel i should try ???

I saw on the VP site the street blaze 100 did anybody has try this fuel...

or is there another fuel i should try on the dyno for max power

Thanks !!

Do you plan on spraying it? If it is a N/A application, I would recommend MS109. This is an oxygenated unleaded fuel that will make really good power and be very consistant. Let me know if you have any other questions.

Thanks,
Jason

Yes it is a N/A engine ... is the 109 similar to the new street blaze 100 ??

The 109 has a higher oxygen content. It will make more power and it isn't that much more than the SB100. I would definitely go with the 109.

Thanks,

A friend just told me he got an untuch can of 103 for me is this the same unleaded oxygenated 109 with less Octane would this be has good for my application on the dyno this week

Thanks !

It will work fine on the dyno. Too bad you couldn't get some 109 and back to back them. Good luck.
