timing advance

[The Don]

Im looking to find out how much the computer advances timing.The car has 14 initial with the spout in and runs 15 lbs. of boost with the btm set at 1.Also what kind of fuel pump do you recommend on a somewhat seroius car with a supercharge to drive everyday and on occassional long trips.Any help would be appreciated.

total timing with the factory base of 10 is 26...so at 14 base you are running 30 total before the btm kicks in...I would suggest a dual walbro setup on a car like yours..something like this:

I recommend total timing in the neighborhood of 17-18 degrees with 93 or 94 octane pump gas with that amount of boost. Im with Eric on the fuel system setup, I run that setup he has pictured with the dual Walbro 255 inline pumps, they are very reliable pumps on a hot street S/C car :wink: BTW be very careful with those BTMs they have a tendacy to not be very accurate in the amount of timing they pull

not to steal your post but what timing should I run with 12psi and I also have a btm what should that be set at. I'm just trying to get a base tune to make the car driveable to the dyno.

and I also run the twin inline walbro setup i'm very happy with it.

Im running 32 deg of timing till 3500 and then backs down to 22 degs. (custom tune)
16 pounds of boost stock fuel lines, 255 intake, trex pusher, and 42# inj.

i'd run 14 base and 1 on the btm with that setup..

test that btm with a fixed air source. you will know exactly how much timing it is pulling out. like eric said the eec will add 16 on top of the base at wot.
