LOL:lol: ummm , you do realize a 106mph trap speed is not gonna come anywhere near what a stock 03-04 cobra or a shelby traps, even the slowest time is mid to low 13's for stock shelby and 03-04 cobras, but even then they still trap in the 107-111+mph range, and good driven 03-04 cobras have trapped 112-114, and shelbys have trapped 115-120 bone stock lol for example heres some cars some people I kno.
Bone stock 2010 shelby gt500
best time stock 12.4@118
stock with tire only 12.15@115
bone stock 2003 cobra
12.8@112
pulley intake exaust,tires,suspension 10.8@124

13.8@103
those are times of 3 people I kno with similar cars, im sorry but even if ur friend runs mid to low 13's esp from a roll with 106 trap isnt gonna cut it, he should race bone stock mach 1's or ls1's.:bash:
he runs 13.5's @ 106 on a 75 shot and pump gas on street tires
he wont run the 100 shot and race gas at the strip untill he gets slicks
