need help in an estimate 1/4 mile

shelbycs6 · August 14th, 2011, 09:45 AM

well guys plan to hit the 1/4 mile this coming wednesday and wanted to see what you guys mostly think i should probably hit.

My car is a 2008 shelby cs6 mustang my mods consist of:

4.0 motor
magna mp90 supercharger on 2.6 pulley(14psi)
intercooled by afco gt500 pro series heat exchanger
roush 3x supercharger coolant reservoir tank
k&n cold air intake
jba stainless steel shorty headers
ford racing mufflers with h pipe along with hollow cats on resonators
ford racing limited slip differenital trac with motive 4.10 gears
riding on 18x9,18x9.5 aluminum wheels with goodyear f1 eagle supercar tires
tuned by 6.0dis on 93 octane
dyno numbers 348rwhp 359rwtq

the track elevation is 70feet above sea level

appreciate if you guys could give me a estimate on what i should hit, my tuner said i should see anywhere between 12.4-12.9 at 107-110mph

Street tires are gonna kill your times. 12.9's@109 is my guess if you can launch it ok.

last time i took the car to the track it was on stock 3.31 gears and one legger..and spun all the way down the track with no air taken out from the tires...i hit 14.7 at 103mph..i want to put drag radials later on but want to see how it should hook if i let air out from the goodyear tires..what psi would you guys recommend so it can hook decently dont plan to rev at the launch cause of the 4.10 gears might be to aggressive on street tires

Don't go lower than 22 psi on street tires. You won't hook on street tires man thats just to much power for hard rubber.

i know bro thats why i want to get some drag radials like micky thompson but low on cash..but thought it should hook a little since i read in the fast ford magazine they got a gt500 to hook on the goodyear stock tires which has 100hp over mine so maybe i can hook it a bit without revving it and launch it hard..plann to baby it from the start then hammer it around 20-30mph
