Ran the Merc at the strip
« on: September 21, 2018, 07:33:30 PM »
13.85 at 102mph

83* and 65% humidity so not great air.  Online calculator said 103mph so seems about right.  Car is 4290 with driver

Short time was 2.20, still running open rear so lots of pedaling in 1-2

I’m fairly happy, it’s either running out of fuel or floating valves at top of fourth, just flattened out last 200ft or so

 Lots of oil downs so been a slow night

63 merc, 390 with BBM heads 224/230 .563 hydraulic roller with 9.2:1, performer rpm and 750dp.  1 3/4 tri us into crush bent 2.5” exhaust.  Tremec TKO 500 with 4.10 gear

103mph is enough to hit 12’s I believe so power seems ok

On second thought it has to be fuel, it’s only turning 5000 or so at the top end so that really can’t be Val float

Maybe to much gear. How tall are tires. Had the same thing went 4.11s to 3.70s now
pulls all the way through and then some. And I have more compression, cam, and motor.
Just thinking out load. ::) ;)
