Hey guys, so I have put some time and money into my 11’ GT500. I need some help figuring out what to do next. Took the car to Do some drag racing over the weekend ..with a not so impressive outing. I bought a set of used m/t street rears ( 28x12.5 x15) and some sve wheels and threw them on. Gotta a 104 octane tune , bp93 and some boostane and hit the strip ( local airport they have drags at. Not a legit track, only 120 ft traction compound. 1 second slower than other tracks) Yes bias in the back radials up front...sketchy on the big end. 18 lbs in the rear tires. Didnt want to go lower because of sway, launching around 4000 and spun alot. Best run was a 12.8 and the rear was moving around alot. Times seemed really slow to me... Mods: Gen2r, 2.42 pulley,67mm tb, jlt 123 cai, 56 lb injectors, 3” side exhaust, 3.73 gears, vmp bap, 170 stat. Koni sports and sportline springs up front and stock svt pp shocks and bmr drag springs in rear. Steeda LCA and UCA. BMR DS loop. (Also have Ford performance alum DS and JBA xpipe cat delete , but not installed) Questions: 1) Do I spend $700 for the sve front wheels and m/t 27.5 tires or do I just buy 20 inch drag radials? I see many guys running killer times with the same mods on DRs. I hear about guys braking parts on DRs on stick cars but i see stock rear set ups running 10s on 20” DR. 2)As far as power Should I buy 72 or 100 lb injectors and put on my JBA x pipe cat/delete to get the most power out of my setup? I believe my injectors are a limiting factor? Any and all advice is appreciated! Thanks in advance!
