MAP is measured against PSIA, not RPM. Depending on conditions, atmospheric pressure is 14.7 PSIA. Vacuum "pressure" is lower (I.E. 15" vacuum = 7.3 PSIA) and naturally, boost (if applicable) is higher. For instance, a "2 BAR" manifold pressure = 14.7 PSIG = 29.4 PSIA.

Are you counting the start and stop points? I think I have 6 with those in the mix...

I have about 40 at idle and cruse down the highway. with the map as soon as it sees load it knocks it down to 29.

Big thing with running more timing is it will drive nicer and MPG should go up some. Just need to make sure when it sees load you kill some so you don't rattle it.

I have 40 in it as high was 3000 with no load.

Does anyone else think this thread should be a sticky?

Here's what I have right now...probably going to actually back off 1-2* across the curve...


Idle-2000 - 20*
2000-3000 - 24*
3000-4000 - 26*
4000-5000 - 27*
5000-5500 - 28*
5500-6000 - 29*



Specs:
383 LS1
238/244 Hyd. Roller
MTI Stg 3 241 Cast Heads
Edelbrock Performer Dual Plane Intake
850 Carb
11.5:1 Compression (I think, could be a little higher)

In a jet boat...

BTW - that timing curve is what my motor liked the best when it was dyno tuned while still injected and in a car (although it preferred 27-28* in the upper rpm, but I forgot until I posted this).

put it all in at 2000 rpm and you need more timing than 29 degrees, i made best mph at 34 degrees, some guys run up to 36 on their combos.

What is your CR?


When this was in my Firebird, I couldn't get more than 30* timing in it with 91 oct. The boat runs the same fuel - only change is EFI to carb...

Hard to make that leap for me - scared to have a "bad day"...remember it's in a jet boat so it's always under load.

I would be willing to bet you will gain MPH and have a quicker ET if you lower total timing.

What kind of fuel are you running?

That sounds similar my setup I was running a few years ago. Mine was a stock 6.0 with 226/228 cam, 850dp, TH350, 3600 stall, 4.56 gears, slicks, and running 32* of timing from 1500 up. My best run that night was 12.8@107 or 109. I was happy with the 12.8 so I didn't bother playing with the timing or carb tune. 32* seemed to work great on that setup and my new setup(different cam, newer heads).

thanks for the thread here.. was having a run on issue with a new l92 carb engine with a bunch of cam.. i am running 20 at idle and ramping up to 31 to be conservative.. but it fixed all. .i am able to run the idle lower .. the AED carb really digs it and all problems solved except the law enforcement ones surely to come.. thank you
