Opinions wanted especially from people actually running a roots blower on the street.

Street driving only!

Carbureted 433” w/671 blower. Shooting for 10psi maximum boost. 330cfm SD ported Edelbrock heads. Cam is a Spotts specked 248/258 @ .050 .541I .541E.

Don’t want to over build for street use only. Was thinking of a 140 lbs/hr Aeromotive SS pump pn11213 with a return style regulator pn13212. 3/8” lines both ways. I already have the regulator.

I don’t drive my car on the street….. I could my engine is more then capable of being street drive BUT what I do know from experience is BIGGER is always better as much as you may not think so people always eventually always want to step up.

Bigger fuel pumps bring problems when street driving...So, bigger isnt always better...

His combo doesnt sound like it'll need a ton of fuel.

Misprint, yes 140 GPH.
93 Octane. Static will be about 7.9:1. Trying to stay safe.

I’m retired George. Just trying to build one last fun car, will never be able to afford “stepping up”, nor do I want to...

I'm not sure what was so funny...Or, is this just another situation where you dont have a clue about the topic?

With the 3/8 lines both way's you'll be fine even at 10 pounds.
The return line is a good way to go and will make things even better.
So go for it.

Let get the specs correct 140 GPH, as I would not run a 140 lbs/hr on an N/A 433 ci engine. What fuel do you plan on running?
