Blower carb help

6-71
468 cid
Dual 750 4150s with boost reference power valves
17.4% underdriven which I calculate it be 2.625 psi boost


What size power valve should I run, what should I install for jetting to begin with

I must ask why 2.5 psi seems hardly worth having the blower. Is it intercooled?

This is just to dial in. Start small work it’s way up. Non intercooled but that amount do boost should still be 55-65 extra hp. So still not nothing

Teague set me up with10.5 power valves but I'm not boost ref. I'd call Teague up hell walk you through the process

What's your static compression? That seems low on the boost. I'm at 17% under and I'm hitting 7psi

Let’s stay on subject. We are debating things that I don’t need to debate

You need to call Cioleck @ AMP.

Good idea. Text me his number.

Get rid of the boost referenced carbs. Get 2 circuit 750 Holleys. 10.5 power valves in them.

That’s what I’m running.

Well I have not done the mod two them yet. They are 2 circuit. Explain why this is better then using a vacuum source to the intake manifold to the power valve directly as advised by multiple sources online including Holley and hot rod

Call Bob Oliver at Competition Carburetion. He did the boost referencing on my carbs and it did wonders.

I've done it this way with 2 Blower motors not that the vacuum carbs don't work IMO it's an added cost not needed.

The power valve will open at 10.5" of vacuum under the carb and enrich the mixture. This is basically when the blower starts to make boost.

Go to 44:20 min and Bob starts to talk about carbureted Blower set up.

ill Take a watch thanks

Why does this need to be a 2 corner idle

 

[BUSTI]

4 corner idle. 2 circuit.
