F1A or F1A-94? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Any one on here with real world experience. Looking to upgrade my P1-X. Wondering if the older F1A design, which makes more power/torque under curve will be better for out heavier cars.

In theory, I feel the -94 makes sense for lighter cars like vettes, but a standard F1A would be better for our 4000lbs cars

I run a f1a with a 3.85 12 rib, it's not quite enough for my setup. Going to be dropping down to a 3.55 to bring it in earlier before eventually going F1x

What kind of boost are you seeing on your application? I know the F1-X is the Mack daddy, but I'm not willing to sacrifice my strut tower to get it to fit. My P1-X is definitely mismatched and out of steam on my application. It makes 8psi with a 3.7 pulley on a 7.0L. I wanted to initially hit the numbers I have, but eventually grow to 16psi.

I am making around 16lbs now on my low compression 7.0L with the size pulley I have right now though I am not picking up real steam until about 3500 rpm. I am wanting to get the F1X and you can massage your strut tower with a hammer I hear...... or have it cut and boxed professionally.

That gives me hope. I can at least achieve the flow I'm looking for. If your F1A isnt picking up steam until 3500, I cant imagine the F1A-94. I know it makes more top end power, but it doesn't pick up steam until 5000rpm.

You can make it fit for sure. I've seen SS's with pro notched strut tower braces. I just dont want to go back sawing on my Z/28 that I like to throw around turns on the occasion.

Thanks for your input!
