All,
I am installing a 123ignition distributor (laptop programmable) into my =
"project" TR6 race car. Wondering if anyone has this installed on their TR6=
(or 250) race car with triple weber 45 DCOEs. I thought about downloading=
the tuning curves from the 123 disti in my running #95 TR6 race car as a =
starting point:.
I realize the camshaft would make a difference in the settings, so my specs=
below. Both have 1.55 roller rockers. Thoughts?
The "project" car engine has a Racetorations race camshaft, triple Weber 45=
DCOE and a CR of about 12.5:1. The camshaft specs are:
Peak Diff: Exh / Intake / LCA - 108.0 / 107.0 / 106.0
Duration: Intake / Exhaust - 336
Cam Lift: Intake / Exhaust - 370
Checking Clearance: Intake / Exhaust - 0.010"
Valve timing (at checking clearance) - Exhaust: Opens 96 BBDC / Closes 60 =
ATDC, Intake: Opens 62 BTDC / Closes 94 ABDC
The camshaft specs in my running TR6 are:
Peak Diff: Exh / Intake / LCA - 105.0 /103.0 / NA
Duration: Intake / Exhaust - 320
Cam Lift: Intake / Exhaust - 340
Checking Clearance: Intake / Exhaust - 0.010" (I think, but not certain)
Valve timing (at checking clearance) - Exhaust: Opens 87 BBDC / Closes 53 =
ATDC, Intake: Opens 57 BTDC / Closes 83 ABDC
Thanks,
Mark Cook
