I realize there are many variables such as prop pitch, twin vs single, cam, CR, etc... But I am just curious what rpm's you guys idle in and out of gear with your Bravo setups with 540-598ci carb motors.

Approximate cam specs, ci, carb setup would be helpful

Thanks,

Dave,
Call me this weekend and I will tell you what ours does. But as you know the computer is playing with the spark advance so it will not be a fair comparision.

Yea, your right Rick... That won't be a fair comparison as I've taken a step back in time with the carb setups

I haven't even tried it yet and the hatch is being modified for clearance so I just have too much time to ponder things.
It does idle pretty nicely at 900 on the trailer though

Just curious how the other carb guys are doing with idle control.

Have fun this weekend! The hatch won't be done til next week so I'll probably be doing yard work

When I had carb it would idle at 850-900 & 750 in gear.

900-950 RPM out of gear
800 in gear

Dont have the cam specs with me right now.

I have a 540 9:5 cr Aluminum heads .672 lift cam. I can idle in gear and shift at 600 rpm. I am set at 800 RPM. Most think this is a EFI 502. This is the best setup I have had. To me your two best friends are a good carb guy and engine tempature.

I had Doug from Braswell do my carb 995cfm 4150 flange demon (yes I know thats a little small)
I used a fresh water cool kit from Monitor Marine and Jerry Sellahowski (sp) at competion products formerly Mercury Racing built the engine.
If you have heat in your engine it helps greatly I am 170 F at idle. 180 wot

Very nice....
I just had Jerry prep me a block and pistons for a build ;o)
He does very nice work!!

Sound like plenty or carb, I am running a ProSystems HP4150 that flows 900 wet on my 588s.

Very encouraging again on the idle...

Thanks,
Dave
