9. Race motor noise: Participant noise levels must be strictly
observed. A maximum of 110 dbA will be permitted with a 108
dbA warning level. All vehicles MUST run mufflers. No race
engines may be started before 7:30 AM or after 6:00 PM.

Whew, I should be good with a street motor running pump gas with 2 mufflers and all.

All true!

The key is which side of the track going the typical configuration is the sound meter on?

Piece of cake!

I'll be there to support you.........

I'm going to do gather dB intel and I'll report back.

Ouch. I can see why it wasn't triple digits. Besides you can do that legally on a track.

Fuel mileage report.......434 miles 15.124 mpg.

Not what I had hoped, but the car resides at 450' asl and most of the trip was between 2,400-5,000' asl. It was fat in the cruise range (12.3-12.9 afr) but altitude was not the primary factor. I'm shooting for mid 14's at cruise.

I need to find a source that can help me identify the 4150 circuit overlaps and influences in the just off idle cruise range.

I'm going to start with leaning the idle feeds in metering blocks and see what happens.

Fuel milage and performance -- with a carb? Isn't that a bit oxymoronic?? LOL

Now with EFI -- you can get that lean A:F mix and performance... But carbs just have their limits with all the transitions. I think 15 mpg with "spirited" driving is pretty dang good. Only takes a couple WOT pulls to knock your average way down.

NO!

I've been researching and reading a bit today........I have direction!
IFR and PVCR will be on order and should get the idle/transfer AFR and WOT AFR in the pro tinkering ballpark. If I can get the cruise in the 14's consistently and WOT at 12.2 - 12.5 it should deliver more power and mileage. H*ll it might even take the Miata at ORP.

I've got over 18 mpg with my carb before...including some autocross runs in those tanks. I regularly average over 15 mpg with a mix of city and highway driving.

Of course, I run a Quadrajet...so that's kind of like cheating at this game.
