1.89 stock everything irs. im on drs and have to pedal because it either spins or hops, and this is my only car as of right now. still runs 11.70s all the time. sra is coming soon.
i have seen many 1.5s out of stock IRS. I launched my car at 4k and cut 1.6 with slipping clutch. 1.5 is very doable but you need some tq to get that pig rolling.
went out again
1st time ----1.88 60 ft on 18 inch BFG DG(315) 11.8 at 119 little better, but had to get out of it the cap for the intercooler poped off. It was f$cking hot outside waiting in line.
2nd time----no traction
