I ran the mark for the first time to get a baseline. I went to an 1/8 mile. i am loking for input to see if i ran good time for stock. only mod it the silencer and snorkle remove no k&n. i called jeff (sierra3) the next day he said that they were pretty good. he said he was in the 10 when he first ran his mark. i clould never beat him with my monte carlo so a traded up and went mark
60ft - 2.3264
330 ft 6.5535
1/8 - 9.9585
mph 72.46
based on thousands of passes at the track, I have come up with an 1/8th mile to 1/4 mile conversion by dividing the 1/4 mile et by the 1/8th mile et..from all those passes, when I do the math the conversion ratio comes out to 1.53 or 1.54
Using that conversion ratio multiplying your 9.95 X 1.54=15.32
Using the 1.53 ratio multiplying your 9.95 X 1.53=15.22
Those are fairly aligned with "advertised" stock Mark 8 numbers.
I can see .2-.3 improvement can be had in the 60' which is where you really want to concentrate on improvments because any "time" you pick up on the 60' multiplies as you go down the track.. meaning if you can turn that 2.32 60 foot into a 2.20 60' your going to pick up more than .12 on the big end, .12 in the 60 could easily be .2-.3 in the full run.
Work on your launch, get your 60's down in the 2.2 range or LOWER and your ET will FALL LIKE A ROCK.
the first 60 feet is FAR more important than the last 1/8th mile, Far more gains to be had in the first 60' than from the 1/8th mile to the 1/4.
9.90's for a baseline is a very good starting point!
Keep us posted!
