[SOSO5.0]

oh yeah i do have a btm sorry

[RdRunnr]

I'd set the base timing at 14 degrees and set the btm at 1.

[SOSO5.0]

i set the base at 14 and btm on 2 car ran a slow 14.79 and never shifted into 4th so i set timing at 20 and btm on 2 and car baked the tires 1st and second and went 12.39 any suggestions?

18psi and 9.75:1 compression, is this a pump gas car? I would keep the total to no more than 16 degrees @WOT with ATLEAST 93 octane. what kinda trap speeds are you seeing with that 12.39????? be careful running that much timing advance with a BTM, they are known to fail and not enough timing and sometimes dont pull ANY timing.

cars is seeing 113mph been best of 10.28 at 133 with previous owner and nothing has changed with set up. pump gas when driven daily raced with race fuel

[blown1989saleen]

20 mph trap difference with no changes????????? something isnt right here, have you checked the mechanical condition of the motor real well? something is way off here, do a leak down and a compression test, check all the blower connections and vacuum lines.
