On say a 468" motor making 925 Hp on single 1300 Dominator does anyone know how much it would pick up with dual Dominators?

Fairly confident it would make more but not sure how much or if it is worth it.

Thanks in advance.

It was worth .10 in the 660' on a 440" small block with 13 degree heads in a 3100 lb car

This particular motor is a 463 " SBC, pretty stout for a SBC but I want a little more. Lol.

The engine im talking about made 890 and 730 and runs 5.60s at 3100 lbs. A single dominator would only run hgih 570s.

That is substantial. I may try dual carbs. Thank you,

From what I've seen and read, the typical gains can be up to as much as 100 hp gain, but it's not due to just the carb.....manifold has a lot to do with it as well. Newer manifold designs and larger carbs have substantially closed that gap though....gains aren't as much anymore, and in some cases, there are no gains, but we're also talking about very high end stuff like MBE's billet intakes and others of similar design...

Your question is fine but you don't provide any specifics. Your carb is sized correctly for the power you state the motor makes so added cfm from 2 carbs will provide small increase in power, not enough to justify the dollars spent. If you do spend the money for a sheet metal intake designed for you motor combo you would likely see some increase in power but no way near the dollars it will take to make the swap unless you hate money!

For another related question on a single four barrel with a small shot of Nitrous would a plate or fogger type system be best?

Note: I know for big horsepower fogger type system would be preferred but I am only going to run 50-100 Hp near finish line to run number.

A fogger system has pills for each runner.
I doubt you can pill it down for 75hp only gain.

A plate would be preferable imho in your case.

That is my thinking to.

Bruce, from my experience unless your converter is really tight, your better off turning on the NOS early in the run. I found hitting it on the top end only raised the RPM and blew thru the converter and didnt make much if any difference in the ET.

That is good information and I always run my converters on loose side. Ran into another issue on the motor but when I get it back together may make a few passes then order a new converter.

Another related question. I am going to need a little more to run the number, planning on adding a touch of Nitrous. Probably only about 100-125 hp.
My question is how well do the Progressive controllers work? Can they be consistent? Or should I go with my original thinking of two stage with first stage about 50 hp and come in about 2 seconds in and then a second stage of 75 come in later and use it to compensate for weather and give me better top speed?

50 - 100 HP with a loose converter will not help you finish line race.

I understand that and will get converter for my combination after I dyno it again and determine exactly how much I need. My question is really about how well the progressive controllers work?

No need for progressive timers. Turn it all on at .050 and off at 3 secs to start with and see where your at. The earlier you turn it on will make the most difference in ET.
