Best race fuel @ sea-level?

[Mr. Pump Gas]

Running an Apex on 22+ lbs boost. Around 375-400hp range. This is with stock internals and stud kit and 3-gaskets.

With brand and octane would be our best bet?

 

[HURRICANE]

With your engine,using stock internals, You want a slow burning gas. For that you don't need as much octane.It's the specific gravity that you need to look at.In our experience,the VP c16 is way overkill on the octane but will burn slow in order to keep your cylinder pressures down so that you don't brake something in the engine

 

[Mr. Pump Gas]

So you think VP C16 would be my best choice?

 

[HURRICANE]

Yes I do

C16 is what we use... your pushing it with stock rods..
